AB  - Cholesterol as very important biomolecule is the precursor of many biologically significant compounds which give strength and flexibility to the biological membranes. It is also a crucial component in lipoproteins, and has an important role to transport hydrophobic molecules in hydrophilic media such as blood [1, 2]. The analytical performance of carbon paste electrodes (CPE) bulk modified with ionic liquid 1-allyl-3-methylimidazolium dicyanamide ([AMIM][DCA]), and surface modified with platinum on graphitized carbon (Pt-C) or platinum-ruthenium alloy on graphitized carbon (Pt,Ru-C) for analysis of hydrogen peroxide (H 2O2) were compared. The prepared working electrodes were characterized using scanning electron microscopy–energydispersive X-ray spectrometry, together with electrochemical impedance spectroscopic, cyclic voltammetric, and amperometric techniques. After method optimization, an enzyme cholesterol oxidase (ChOx) was immobilized on the surface of Pt,Ru-C/IL-CPE by Nafion®. The improved cholesterol amperometric determination was achieved in phosphate buffer solution pH 7.50 at a working potential of 0.60 V. Under the optimized experimental conditions, a linear relationship between oxidation current and cholesterol concentration was in the concentration range from 0.31 to 2.46 µM, with an estimated detection limit of 0.13 µM and relative standard deviation (RSD) below 4.2%. The optimized amperometric method in combination with the developed ChOx/Pt,Ru-C/IL-CPE biosensor showed good repeatability and high selectivity towards cholesterol biosensing despite the presence of possible interferences. The ChOx/Pt,Ru-C/IL-CPE was tested for the determination of the free cholesterol, by its enzymatic reaction product H 2O2, in a human blood serum sample. The percentage recovery ranged from 99.08 to 102.81%, while RSD was below 2.0% for untreated, as well as for spiked human blood serum sample.

AB  - The increasing popularity of luminescent nanothermometry in recent years can be attributed to its application potential in biomedicine. In response to this need, we describe a biocompatible bimodal luminescent thermometer that operates in ratiometric and luminescence lifetime modes based on particles of MgTiO3:Cr3+,Nd3+@SiO2. The introduction of Cr3+ and Nd3+ dopants enabled the luminescence of Ti3+ ions to be observed, and the difference in the thermal quenching rates of Cr3+ (4T2→4A2), Ti3+ (2T2→2E) and Nd3+ (4F3/2 → 4I11/2) ions enabled the ratiometric thermometers. The highest sensitivity reaching SR = 1.00%K−1 was obtained for MgTiO3:0.1 % Cr3+, 0.1 % Nd3+ at 203 K. The shortening of the lifetime of the 4T2 level of Cr3+ ions associated with its thermal depopulation allows to develop a lifetime-based thermometer with a relative sensitivity reaching 0.85–1.18%K−1 in the physiological temperature range. The deposition of a SiO2 shell on a MgTiO3:Cr3+,Nd3+ did not introduce significant changes in the shape of the emission spectrum and slightly elongates the lifetime by reducing the probability of surface-related nonradiative processes. More importantly, the thermometric performance of this luminescence thermometer was preserved. The low cytotoxicity of the obtained materials underlines their potential in bioapplications of the described luminescent thermometers.

AB  - Carbon quantum dots (CQDs) are well known as a promising therapeutic agent due to their excellent pro-oxidant, antioxidant, antibacterial and anticancer properties under visible light irradiation. This material is easy to produce by several bottom-up or top-down methods. In this study, we used citric acid as starting precursor to synthesize aqueous carbon quantum dots dispersion by pyrolysis at 210 ◦C. Atomic force microscopy and XPS analyses revealed that CQDs synthesized are quasi-spherical with typical diameter of 9 nm and lots of C–O and C––O functional groups distributed over the basal plane and edges of the dots. Here, we investigated the antiviral properties of CQDs against cytomegalovirus (CMV). The pre-treatment with CQDs upregulates interferonstimulated genes (ISG), resulting in better virus control. Cellular defence against cytomegalovirus of CQDs pre-treated cells is increased in a dose-dependent manner. Our results reveal high biocompatibility and potent in vitro antiviral properties of CQDs.

AB  - Eu3+ doped Zirconia coatings were synthesized by the electrochemical plasma electrolytic oxidation method in only 8 min from the pure zirconium substrate. The phase constitution from pure monoclinic to pure tetragonal and exactly in between was achieved by using different concentrations of Na3PO4 and NaAlO2 electrolytes. The complex emission spectra composed of Eu2+, Eu3+, and ZrO2 defect emission greatly depend on the excitation wavelength and phase constitution. Eu3+ photoluminescence properties depend on the phase, which is reflected by the different Stark splitting and different intensities of transitions. Thus, both phase and photoluminescent properties of ZrO2 coatings are fine-tuneable. Judd-Ofelt analysis was performed from the emission and excitation spectra, showing that all 3 intensity parameters depend linearly on the phase constitution, being largest in the pure monoclinic phase. The mixed phase has Judd-Ofelt parameters between those in pure phases. Eu3+ has 2.45 times more preference to get incorporated into the tetragonal than in the monoclinic phase in the mixed phase samples. The general equation for Judd-Ofelt parameters in a compound with mixed constituents and probability of incorporation is introduced, allowing also for a prediction of the spectrum shape based on the Judd-Ofelt parameters of pure-phase compounds. Python software code for estimating the percent of incorporation by multiple linear regression model is also provided.

AB  - We report on the results of the first principles calculations based on density functional theory (DFT) of the electronic structure and mechanical properties of K2LiAlF6, both non-doped and doped with Cr3+ ions. The densities of states of K2LiAlF6 and the K2LiAlF6:Cr3+ phosphor as well as the crystal-field strength 10Dq, the Cr3+ 2E→4A2 emission energy, elastic constants, bulk and shear moduli, sound velocities and Debye temperature as functions of hydrostatic pressure ranging from 0 up to 40 GPa were calculated. The present DFT calculations indicate that, the band gap of non-doped K2LiAlF6 increases quadratically with increasing pressure. Further, the crystal field strength 10Dq and the 2E→4A2 emission energy, the Debye temperature, sound velocities and shear moduli of Cr-doped K2LiAlF6 increase with increasing pressure, while the 2E→4A2 emission energy becomes red-shifted, which indicates potential applicability of the studied system for pressure sensing. Such calculations for the title system were performed for the first time; the obtained results provide a firm basis for a deeper understanding of physical properties of both neat and doped functional materials.

AB  - Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification in order to obtain a highly efficient and sterile sorbent. The characterization of fig pomace before and after pyrolysis, as well as before and after irradiation of the obtained pyrochar, was done using SEM, FTIR, and elemental analysis, while its sorption ability was tested through the removal of examined pollutants by batch sorption experiments. The obtained results suggest that IrrPyrFP could play a significant role in the control of environmental pollutants, as indicated by the maximum adsorption capacities: 42 mg g−1 for BTEX, 0.625 mg g−1 for malathion, 0.495 mg g−1 for chlorpyrifos and 255 mg g−1 for Pb2+. A kinetic study showed that the removal process by IrrPyrFP mainly follows pseudo 2nd kinetics order, while the sorption equilibriums were estimated using the Langmuir and Freundlich model. Overall, the findings of this work suggest that pyrolysis and activation by irradiation of waste biomass is a promising way to produce sterile efficient sorbents for waste-water treatment based on green chemistry. Additionally, the demonstrated application of fig pomace promotes the potential of using this biomass for continual and economical waste management in the rising fig industry.

abstract = "Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification in order to obtain a highly efficient and sterile sorbent. The characterization of fig pomace before and after pyrolysis, as well as before and after irradiation of the obtained pyrochar, was done using SEM, FTIR, and elemental analysis, while its sorption ability was tested through the removal of examined pollutants by batch sorption experiments. The obtained results suggest that IrrPyrFP could play a significant role in the control of environmental pollutants, as indicated by the maximum adsorption capacities: 42 mg g−1 for BTEX, 0.625 mg g−1 for malathion, 0.495 mg g−1 for chlorpyrifos and 255 mg g−1 for Pb2+. A kinetic study showed that the removal process by IrrPyrFP mainly follows pseudo 2nd kinetics order, while the sorption equilibriums were estimated using the Langmuir and Freundlich model. Overall, the findings of this work suggest that pyrolysis and activation by irradiation of waste biomass is a promising way to produce sterile efficient sorbents for waste-water treatment based on green chemistry. Additionally, the demonstrated application of fig pomace promotes the potential of using this biomass for continual and economical waste management in the rising fig industry.",

AB  - Increased fructose intake via industrial food is associated with metabolic syndrome(MetS). MetS is characterized by chronic low-intensity inflammation caused by oxidativestress and activation of the renin-angiotensin system (RAS). Walnuts are a rich source ofantioxidants and polyunsaturated n-3 fatty acids that exert anti-inflammatory/immunomodulatory effects on cardiometabolic health, which molecularbackground is underexplored.Walnut consumption (2.4 g/day, 6 weeks) reduced systolic blood pressure in ratsfed a fructose-rich diet (10% FRD, 15 weeks), showed a protective effect on theantioxidative axis SIRT1-FoxO3a-MnSOD/catalase and anti-inflammatory cardiac capacity(AA/EPA reduction) and promoted the anti-inflammatory profile of plasma fatty acids(AA/EPA and AA/DHA reduction), which were compromised by FRD. The role of theaxis negative regulators, Nox4 and ChREBP, should be further investigated in the heartbecause the Nox4 level was increased by both, FRD and walnut supplementation, whilethe ChREBP nuclear level was reduced in FRD as well as in control rats subjected towalnuts. FRD activated a signaling pathway that regulated inflammation by increasing thelevels of the transcription factor NF-κB and the key RAS enzyme, ACE, while walnutsupplementation in FRD rats increased ACE2 level, a cardioprotective component of theRAS. The protein/mRNA levels of the RAS receptors, AT1R and AT2R, were not affectedby either of the two nutritional factors.This study confirmed the beneficial effects of walnut consumption oncardiometabolic status and proposed the mechanisms underlying their anti-inflammatoryand antioxidative effects in the heart, indicating the possibility for development of novel,non-pharmacological approaches in cardiometabolic disease therapy.

AB  - Utilization possibilities of solidified fractions of industrial hazardous waste obtained by mixing
with inert materials in construction were investigated. Waste mineral oils, water-hydrocarbon
emulsions mixture, and waste filter cakes from the physico-chemical treatment of wastewater
generated by washing of patterned rollers for a printing machine, were used as models of
industrial hazardous waste in the solidification process. Investigation comprised preparation of
concrete and asphalt mixtures for further testing. The solidified powder was analyzed regarding
the granulometric composition, while the obtained concrete samples were further subjected
to compressive strength determination, whereas the asphalt mixtures were tested in the
context of potential waterproofing materials. According to the obtained leaching test results,
all the samples met the required conditions for further application. Compressive strength test
results were in the range of 8.7 – 22.6 MPa. Still, the measured compressive strength values
were lower than expected, which is explained using solidified powder fractions of smaller grain
size. According to the results, it can be concluded that the investigated mixtures cannot be used
for structural building elements, but their usage is recommended for elements such as
pavements, roadside, path cubes, concrete haberdashery, etc. Asphalt mixtures showed
acceptable properties in terms of mechanical, durability, and waterproofing tests.

Prema dobijenim rezultatima ispitivanja luženja, svi uzorci su ispunjavali potrebne uslove za dalju primenu.
Rezultati ispitivanja čvrstoće na pritisak bili su u opsegu od 8,7 – 22,6 MPa. Izmerene vrednosti čvrstoće na
pritisak bile su niže od očekivanih, što se objašnjava upotrebom solidifikovanih frakcija manje granulacije.
Na osnovu dobijenih rezultata može se zaključiti da se ispitivane mešavine ne mogu koristiti za
konstruktivne građevinske elemente, te se preporučuje njihova upotreba za građevinske elemente kao što
su trotoari, ivičnjaci, kocke za staze, betonska galanterija i dr. Asfaltne mešavine su pokazale prihvatljiva

AB  - Elevation in the electronics industry has experienced a significant increase in the amount of waste generated, resulting in the generation of a substantial amount of electrical waste (E-waste). The excessive usage and production of cathode-ray tubes (CRT), a critical component of older monitors and screens, has become a significant environmental issue globally over the past few decades. With the advent of novel technologies, CRTs have been almost entirely replaced. It is now essential to develop new and renewable methods to manage CRT glass waste. The reuse of CRT waste glass for the manufacturing of new products or as an admixture to existing ones presents a significant opportunity, and thus it is obligatory to find contemporary ways to recycle this waste. Grounded CRT waste glass has been found to have a positive impact when used as a fine aggregate, but it is classified as hazardous due to its high lead content. However, after comprehensive series of cleaning and grinding the utilization of CRT glass can be beneficial in various fields. This paper focuses on reviewing recent developments related to the reuse of CRTs, and the aim is to evaluate the feasibility of its safe application in the art field.

AB  - In this study, the applicability of construction and demolition waste (C&DW) in geopolymerization technology was investigated. The C&DW components, concrete and solid bricks, were collected from demolition sites in Belgrade, Republic of Serbia. The concrete sample came from a demolished fifty-year-old construction road, while the remains of solid bricks originated from a 1930s building. Prior to mechanical testing, the C&DW components were characterized by XRD analysis for their mineralogical composition. The results showed that the concrete waste consisted mainly of quartz (SiO2) and calcite (CaCO3), while the brick waste sample contained anorthite from the feldspar group (CaAl2Si2O8), wollastonite (Ca0.957Fe0.043O3Si) and mullite (Al2.4O4.8SiO6). The mechanical properties were examined using the screening method on three geopolymer mixtures, one of each mixture of concrete and brick powders and a mixture of both C&DW components. According to the standard SRPS EN 12390-3:2010 for cubic samples, the geopolymer samples were prepared with alkaline activators for testing the compressive strength as the dominant parameter in the mortar and concrete evaluation. The compressive strength values increased in the range of 2.4 MPa for concrete, 10.2 MPa for brick, and 10.8 MPa for the mixed geopolymer sample. The low compressive strength result of the concrete sample was the consequence of the mineral composition, i.e., the absence of aluminosilicate. However, the brick and the sample with a combination of both types of waste showed moderately satisfactory compressive strength, which could be the starting point for further investigations.

AB  - Direct application of heavy metals as antibacterial agents can cause skin irritations and discoloration of the tissue and it can result in short-term applicability. One of the ways to solve these problems is to immobilize these agents on bentonite. Treatment of textile materials with such activated bentonite for use in various branches of industry has attracted the attention of many researchers in recent years. The objective of the present study was to develop a potential use of Cu- and Zn-modified bentonites as antibacterial finishing agents for two textile materials, non-woven textile (NT) and knitted fabric (PL). The bentonite samples were characterized using ED-XRF (energy dispersive X-ray fluorescence spectrometry), XRPD (X-ray powder diffraction), SEM (scanning electron microscopy), FTIR (Fourier-transform infrared spectroscopy), and BET (N2 adsorption-desorption) analyses. SiO2 and Al2O3 oxides were the main components of all bentonite samples indicated by ED-XRF analysis, while the XRPD analysis confirmed that the natural bentonite (NB) consisted of montmorillonite (Mnt) as the dominant mineral (peaks at 6.94, 19.94, 35.09, and 54.09°2θ) and small amounts of quartz and calcite. A reduction in the basal plane spacing, d 001, of Mnt occurred in Cu/Zn-B1, Cu/Zn-B3, and CuB, while in Cu/Zn-B2 and ZnB the basal spacing increased. Also, the size and form of particles and porosity changed, which was confirmed by the BET analysis. Modified bentonite samples experienced a reduction in the specific surface area and total pore volume, as well as movement of the middle mesopore diameter toward the larger diameters. The Zn-modified bentonite demonstrated a greater antibacterial effect on Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus cereus than Cu- and Na-modified bentonite samples with a MIC (minimum inhibitory concentration) of 0.94 mg/mL, while among Cu/Zn bentonite samples, Cu/Zn-B2 had the strongest antibacterial effect (MIC 0.47 mg/mL). Cu/Zn-B2 was integrated on NT and PL using a screen printing method and showed good antibacterial activity. The printed NT showed better activity than printed PL, and increasing the concentration of applied Cu/Zn-B2 also increased the antibacterial properties.

AB  - The development of energy-efficient and low-carbon geopolymer-based paving blocks made from waste, as an environmental-friendly material, was evaluated. Ground concrete (GC) and solid brick (SB) powder, as the representatives of construction and demolition waste (C&DW), with the addition of fly ash (FA) and silica fume (SF), were used. Waste samples were characterized in terms of surface functional groups and radioactivity. The FT-IR spectra showed the required amorphous or semi-crystalline alumino-silicate structure. The gamma spectrometry confirmed waste samples' radiological safety. Hardened geopolymer samples were subjected to physical-mechanical investigation comprising of density, water content, compressive and flexural strengths determination. Based on strength characteristics, the three best prototype mixtures were selected and subjected to further compressive strength determination and durability assessment. Prototype sample SBFASFp1, with a compressive strength of 18.7 MPa, was shown the highest value of all samples, almost the same as the corresponding SBFASF1 sample. Freeze-thaw and the subsequent carbonation tests, as durability indicators, showed that the SBFASF1 sample had the slightest strength decrease, making it most durable in these conditions. These satisfactory test results showed the favorable effects of alternatives to cementitious materials, encouraging their utilization and contributing to the sustainability of the construction sector.

AB  - The rapid progress of the electronic industry has led to the generation of a large amount of electrical waste before the end of its useful life. Illegal disposal of old monitors and TV screens, i.e. their Cathode-Ray Tubes (CRT), represents a major concern for the environment being CRT waste is classified as hazardous due to its high lead content. Therefore, the final disposal of this waste must be preceded by treatment in a smelter in order to separate the lead from the glass. The current practice in the Republic of Serbia (RS) is additionally complicated by the lack of such facilities, which requires the export of CRT to Western Europe at an additional cost. Previous research indicates the possibility of CRT glass utilization in the production of bricks, ceramic tiles, and special rooms for the disposal of nuclear waste or as an aggregate in construction. Also, the partial substitution of cement with fine ground CRT glass reduces the amount of its consumption, increasing the level of sustainability of this process. This paper deals with the investigation of CRT glass usage in cement materials, in order to evaluate the possibility of its use in mortar-matrix for the immobilization of liquid radioactive waste.

AB  - Broj pretnji od kriminalnih ili neovlašćenih radnji koje uključuju nuklearne i druge radioaktivne materijale značajno je porastao u poslednjih 30 godina. Različiti nedržavni akteri poput terorističkih organizacija i organizovanih kriminalnih grupa pokušavaju da dođu do ovog materijala u okviru permenentnih pokušaja da proizvedu oružje za masovno uništenje. Nezakonita trgovina radioaktvinim materijalima podrazumeva namerno, ilegalno kretanje radioaktivnih materijala, uključujući nuklearni materijal, radi terorističkog, političkog ili nezakonitog profita. S tim u vezi, fokus bezbednosnih napora je na sprečavanju nedozvoljene trgovine nuklearnim i drugim radioaktivnim materijalima. Borba protiv ilegalne trgovine radioaktivnim materijalima putem opšte prevencije je odgovornost svake države. Države realizuju čitav spektar bezbednosnih mera kao odgovor na pokušaje ilegalne trgovine i nenamernih kretanja radioaktivnih materijala kao deo nacionalnih aranžmana države. Otkrivanje radioaktivnih materijala na granicama predstavlja ključnu komponentu ukupne strategije kako bi se osiguralo da takvi materijali ne dođu u ruke terorističkih grupa i drugih kriminalnih organizacija.
AB  - Studies have shown that threats of criminal or unauthorized acts involving nuclear and other radioactive materials have increased significantly in the last 30 years. Numerous non-state actors as terrorist groups have permanently tried to acquire this material as a part of their attempts to produce a weapon of mass destruction. Deliberate, illegal movements of radioactive materials, including nuclear material, for terrorist, political, or illegal profit is generally understood to be illicit trafficking. In this regard, the focus of security efforts is on the prevention of illicit trafficking of nuclear and other radioactive materials. Combating illicit trafficking of radioactive materials through general prevention is the responsibility of each State.

abstract = "Broj pretnji od kriminalnih ili neovlašćenih radnji koje uključuju nuklearne i druge radioaktivne materijale značajno je porastao u poslednjih 30 godina. Različiti nedržavni akteri poput terorističkih organizacija i organizovanih kriminalnih grupa pokušavaju da dođu do ovog materijala u okviru permenentnih pokušaja da proizvedu oružje za masovno uništenje. Nezakonita trgovina radioaktvinim materijalima podrazumeva namerno, ilegalno kretanje radioaktivnih materijala, uključujući nuklearni materijal, radi terorističkog, političkog ili nezakonitog profita. S tim u vezi, fokus bezbednosnih napora je na sprečavanju nedozvoljene trgovine nuklearnim i drugim radioaktivnim materijalima. Borba protiv ilegalne trgovine radioaktivnim materijalima putem opšte prevencije je odgovornost svake države. Države realizuju čitav spektar bezbednosnih mera kao odgovor na pokušaje ilegalne trgovine i nenamernih kretanja radioaktivnih materijala kao deo nacionalnih aranžmana države. Otkrivanje radioaktivnih materijala na granicama predstavlja ključnu komponentu ukupne strategije kako bi se osiguralo da takvi materijali ne dođu u ruke terorističkih grupa i drugih kriminalnih organizacija., Studies have shown that threats of criminal or unauthorized acts involving nuclear and other radioactive materials have increased significantly in the last 30 years. Numerous non-state actors as terrorist groups have permanently tried to acquire this material as a part of their attempts to produce a weapon of mass destruction. Deliberate, illegal movements of radioactive materials, including nuclear material, for terrorist, political, or illegal profit is generally understood to be illicit trafficking. In this regard, the focus of security efforts is on the prevention of illicit trafficking of nuclear and other radioactive materials. Combating illicit trafficking of radioactive materials through general prevention is the responsibility of each State. There are a number of response measures to the illicit trafficking and inadvertent movements as part of a State’s national arrangements. Detection of radioactive materials at borders is an essential component of an overall strategy to ensure that such materials do not fall into the hands of terrorist groups and other criminal organizations that could supply them.",

AB  - In recent years, due to economic and political instability around the world, there has been growing concern over the possible infiltration of counterfeit, fraudulent and suspect items (CFSIs) into the nuclear supply chain. CFSIs do not undergo the same rigorous quality assurance procedures as legitimate items, and deviate from prescribed specifications. Within the nuclear supply chain, CFSIs can diminish the integrity of equipment, systems, structures, components or devices that contribute to nuclear safety and/or nuclear security. The inadvertent introduction or malicious insertion of CFSIs within the nuclear supply chain could lead to the occurrence of a nuclear security event. Prevention and risk assessment are essential in containing the security consequences of illicit trade, and technology could play a central role in monitoring – with the aim of reducing the resources available to politically motivated and terrorist actors. Therefore, it is necessary to develop measures to mitigate the nuclear security implications of CFSIs that have infiltrated the nuclear supply chain, or prevent their introduction altogether. Quality Assurance requirements for each supplier category and the quality classification of the procured item or service should be part of CFSI Program as an integral part of the Integrated Management System and Quality Assurance Program. It is of great importance to make comprehensive review of existing international legislations and regulations which refers to CSFIs and to look into procurement process in the light of nuclear security implications of CFSIs.

AB  - Problem u korišćenju stručne terminologije je u poslednje vreme sve izraženiji. Jedan od uzroka za takvo stanje leži u činjenici da je engleski jezik ušao u svakodnevnu upotrebu. Pored toga, činjenica da se srpski standardi objavljuju na engleskom jeziku preuzimanjem međunarodnog ili evropskog standarda još više doprinosi produbljivanju ovog problema. Korišćenje različitih termina za isti pojam može se razrešiti uvođenjem Rečnika stručnih termina. U radu su diskutovane opcije za nekoliko često korišćenih termina.
AB  - The issue of using professional terminology has been more apparent in recent times. One of the reasons for such occurrence is the fact that English language has been widely used on regular basis. In addition, the fact that the Serbian standards have been adopted in English language additionally contributes to deepening this issue. The use of varying terms for the same notion can be overcome by introducing the Dictionary of Professional Terminology. This paper looks into the options for several frequently used terms.

AB  - Hydrogels possess distinctive characteristics that can be tailored to meet specific needs, especially in the field of biosciences, which is continuously expanding and advancing. Adjustability of gel porosity, followed by tunability of swelling properties, environmental responsiveness, and stability, are properties that are easily adjusted, offering researchers and engineers the flexibility to fine-tune these properties to suit the specific requirements of diverse applications. As a result of environmental responsivity, one class of these materials emerged, referred to as stimuli-responsive or smart hydrogels. Such hydrogels can change their properties in response to specific external stimuli or environmental conditions in a controlled and reversible manner. Depending on the specific type of smart hydrogel, this feature can enable targeted drug delivery, tissue engineering, and controlled release systems while maintaining their biocompatibility. Poly(N-isopropylacrylamide) (PNiPAAm) is a thermosensitive polymer with a well-defined volume phase transition temperature (VPTT) around 32°C. Conversely, silver nanoparticles (AgNPs) continue to preserve academic interest due to their size-dependent optical, catalytic, and electronic properties, as well as their significant antimicrobial potential. One of the primary obstacles encountered by scientists is establishing the broader range of practical applications of AgNPs as well as improving the existing ones. Optimizing their properties often involves controlling size and shape, stability, and surface properties. In order to determine how anizotropic Ag NPs alter and influence the physicochemical properties of PNiPAAm we present a simple, straightforward two-step synthesis of AgNPs/PNiPAAm hydrogel nanocomposites. This method involves the chemical synthesis of both spherical and triangular AgNPs, followed by the crosslinking of PNiPAAm through gamma irradiation in the presence of nanoparticles. The validation of employing gamma irradiation is based on the fact that this technology integrates the processes of sterilization and synthesis, resulting in a consolidated technical step that enhances efficiency and enables the exploration of numerous innovative biomedical applications. The porous sponge-like structure was observed by SEM analysis, while the formation of stable and uniformly distributed AgNPs in the polymer was confirmed by UV-VIS spectroscopy. Swelling and deswelling processes were performed in water at 25C and 48C, respectively. In addition, AgNPs were shown to influence VPTT values. The primary objective of this study is to examine the correlation between various morphologies of AgNPs and the physicochemical characteristics of nanocomposite samples. This investigation considers the possible uses and the current demand for the extensive utilization of biocompatible materials.

AB  - Differently-shaped TiO2 photo-nanocatalysts play a principal role in the remediation of environmental and pollution challenges considering their proven potential for treating organic contaminants in wastewaters [1]. However, increasing the photoactivity of TiO2 i.e. its optical response from UV into visible region is a constant challenge of many ongoing researchers [2]. An proceed towards this demand may be the creation of hybrid functional nanocomposites by coating the TiO2 nanocrystals (NCs) with electronically coupled conductive polymers (e.g., polyaniline (PANI), polypyrrole, etc.) [3]. By the carbonization process of mentioned conductive polymers at high temperatures, obtained final material possess carbon-like structure which impart additional properties [4]. Thus, the evolution of carbonized PANI (CPANI)- coated TiO2 NCs opens up the possibility for tailoring the photocatalyst with distinctive properties. This study implies development of new nanocomposites based on CPANI and colloidal TiO2 nanoparticles (NPs) (TPC) and CPANI and TiO2 nanotubes (NTs) (TTPC). Sol- gel and hydrothermal synthesis paths were used to obtain TiO2 NCs. The influence of their size and shape on the photocatalytic activity of formed carbonized nanocomposites was estimated. TPC and TTPC nanocomposites were synthesized according to the steps: 1) the non-carbonized PANI/TiO2 class was firstly prepared by the chemical oxidative polymerization of aniline with ammonium peroxydisulfate in the presence of TiO2 NPs or NTs and 2) the subsequent carbonization process was applied (650 °C). Developed hybrid nanocomposites were morphologically and structurally characterized by TEM measurements and Raman spectroscopy, while their functionality was estimated through the photocatalytic degradation processes of Methylene blue and Rhodamine B. All TPC and TTPC nanocomposites showed excellent photocatalytic properties, however, shape-depending of used TiO2 NCs.

AB  - Photoelectrochemical (PEC) cells for solar-energy conversion have received huge interest as a promising technology for renewable energy production. For the efficient application of such cells, it is necessary to develop adequate photoelectrodes. Recently, bismuth vanadate (BiVO4) has emerged as a promising photoanode due to its visible light harvesting properties, band edge positions and low-cost of synthesis. In this study, the effects of N5+ ion irradiation (75keV, 2 × 1014 and 4 × 1014 ions/cm2 ) on physicochemical properties of hydrothermally synthesized BiVO4 thin films were examined. From X-ray diffraction (XRD) study can be concluded that initial monoclinic material didn’t sustain any phase transition after irradiation. Also, preferential orientation remained dominantly along [010] direction with a slightly increasing share of [121] oriented growth, especially after irradiation with 2 × 1014 ions/cm2 . XRD measurements showed shift towards the higher 2θ after irradiation which indicates that interplanar distances decreases. The highest level of crystallinity was observed for the sample irradiated with fluence of 4 × 1014 ions/cm2 . Scanning electron microscopy (SEM) revealed prismatic morphology of all samples with an average grain size of 600 nm without visible traces of irradiation.Raman spectroscopy confirmed presence of bands that correspond to the monoclinic scheelite phase. X-ray photoelectron spectroscopy (XPS) analysis of V 2p confirmed presence of V5+ and V4+ while analysis of O 1s confirmed presence of oxygen in the form of lattice oxygen and in the form of hydroxide. UV-Vis Diffuse Reflectance spectroscopy revealed that calculated band gap decreases with the increase of fluence.

AB  - In recent years, drug delivery systems have been one of the most investigated solutions for safer and more efficient therapy. Among many investigated materials, hydrogels with incorporated drugs and/or active substances can be produced in different ways to meet the criteria of biocompatibility, non-toxicity, continuous drug delivery, etc. In our previous work, the Ag- P(NiPAAm/IA) hydrogel nanocomposites were produced by radiolytic method, which enabled the synthesis and sterilization of materials in one technological step. Because of silver ions release, these hydrogel nanocomposites showed good antibacterial potential against both gram- positive and gram-negative bacteria. In this study, we go a step forward and investigate the silver release mechanism by fitting experimentally obtained data with several commonly used kinetics models of drug release.

AB  - Radioaktivni izotop barijuma Ba-133 (t1/2 = 10,55 god.), generisan u nuklearnim reaktorima, testiranjem nuklearnog oružja, drugim nuklearnim aktivnostima i akcidentima, dospeva u životnu sredinu atmosferskom emisijom, putem kontaminiranih voda i izluživanjem iz otpada.

Rezultati su pokazali da se joni Ba preferentno vezuju u odnosu na Sr nezavisno od tipa zeolita, ali su kapaciteti i efikasnost sorpcije Ba, kao i oba katjona u uslovima kompeticije, značajno veći primenom Z4A.

AB  - The radioactive barium isotope Ba-133 (t1/2 = 10.55 y), generated in nuclear reactors, nuclear weapons testing, other nuclear activities, and accidents, reaches the environment through atmospheric emission, contaminated water and leaching from waste. Considering that the efficiency of pollutant separation from aqueous media using zeolites depends on many process factors, tests are necessary to ensure their optimal use in specific conditions. This work studied the removal of Ba ions by natural clinoptilolite and synthetic zeolite 4A from one-component solutions and two-component mixtures of Ba and Sr ions, under equilibrium conditions. The results showed that Ba ions bind preferentially compared to Sr regardless of zeolite type. However, the capacity and efficiency of Ba sorption and sorption of both cations under competing conditions are significantly higher with the use of Z4A. The total ion sorption capacity increases in two-component systems, indicating the participation of additional active zeolite centers in the presence of Sr ions.

AB  - Due to their wide application in industry, medicine, agriculture, and various research fields, the number of sealed radioactive sources (SRS) in the world is constantly increasing. In SRS, the radioactive material is hermetically sealed in a suitable capsule to prevent contact with the environment under normal conditions of use. In cases where such a source is replaced by another technique, becomes obsolete, has insufficient activity or is damaged, it is declared as a disused sealed radioactive source that can still be highly radioactive and potentially dangerous for human health and the environment. A large number of accidents have been recorded worldwide, so adequate management is a priority with the aim of preventing accidents of this type. The disused sealed radioactive source is not necessarily radioactive waste, so other options are considered before declaring it as such.
