AB  - The interaction between charge carriers and phonons is the primary mechanism through which charge carriers exchange energy with the crystal lattice. A proper understanding of the electron-phonon interaction is of great importance. We conducted a comprehensive investigation to examine the electron-phonon interaction in semiconductor crystals of Zn1-xCdxGeAs2 (0 ≤ x ≤ 1). For this objective, X-ray diffraction, far-infrared reflection, and Raman scattering studies were employed. In addition to the two primary phases, namely ZnGeAs2 and CdGeAs2, four component phases were also identified: ZnAs2, CdAs2, GeAs, and GeAs2. A spatially inhomogeneous distribution of charge carriers was detected, with the highest concentration in the vicinity of the formed GeAs. Analysis of the Far-infrared reflection spectrum of ZnGeAs2 (x = 0) revealed that plasmon-4 phonon interaction occurs, while in CdGeAs2 (x = 1), there is a plasmon-3 phonon interaction. All other samples have both of these interactions, according to their percentage in the composition. Raman measurements revealed that due to the influence of free charge carriers, there is an increase in the intensity of phonon modes, their displacement, or their splitting into two modes. The intensity and the way the electron-phonon interaction vary depending on the local concentration of free carriers, and it is the strongest in the areas around the formed GeAs.  The obtained results and performed analyses revealed the existence of different phases in the material, inhomogeneous charge distribution, and electron-phonon interaction, which are essential properties of thermoelectric materials.

AB  - In this paper, the coordination of 4-methylpyrazole (L) to Ni(II) and Zn(II) ions is studied through the reactions of Ni(OAc)2·4H2O and Zn(OAc)2·2H₂O with 4-methylpyrazole in a 1:2 metal-to-ligand molar ratio in ethanol at room temperature. From the reaction mixtures, new complex compounds of formulae: [Ni(OAc)2L4] and [Zn(OAc)2L2] were crystallized. The crystal and molecular structure of the synthesized complexes were determined by single-crystal X-ray structure analysis. The coordination environment of Ni(II) in its complex is octahedral, while that of Zn(II) is tetrahedral. The compounds are characterized by IR spectra and elemental analysis. Their thermal stability, a crucial property, is analyzed by thermogravimetry. To get a better insight into the decomposition mechanism coupled TG-MS measurements were carried out, too. The tests of the antioxidative activity of the new complexes on DPPH radical showed that the Zn(II) complex is more effective than the Ni(II) complex.

AB  - In this work, Cu(II) complexes with meso‑HMPAO and d,l-HMPAO were synthesized. The structural characterisation of the isolated compounds has been done by single-crystal X-ray diffraction analysis, FTIR, and mass spectroscopy. Redox properties of complexes and binding to deoxyribonucleic acid (DNA) molecule have been analysed in detail by cyclic voltammetry and DFT calculations. The results of cyclic voltammetry fully agree with the data obtained by DFT calculations and indicate that the first electron removal takes place from the metal, while the second electron is removed from the ligand. The formation of the complex leads to the shift in oxidation peaks of the ligand from ‒0.29 V to 0,47 V and from 1.18 V to 1,24 V, indicating that ligand in the complex is much more difficult to oxidize. Electrochemical data confirmed the binding between the complex and DNA molecules through guanine. DFT calculations show that the complex is suitable not only for binding purine and pyrimidine bases through a coordination bond but also for additional hydrogen and CH-π interactions of the bases with the ligand. The fluorescence titration experiments revealed a moderate binding affinity of the [Cu-HMPAO]ClO4 complex to human serum albumin (HSA). Molecular docking revealed that this ligand preferentially binds to drug binding site 3 of HSA. Therefore, the novel compounds could be of great interest for further investigation, considering the potential anticancer activity, and as a model for the development of radiopharmaceutical with 64Cu.

AB  - Development of nuclear technology for clean energy and scientific research presents increasing challenge for radiation protection. At the same time, development of robotic technology and new materials presents an opportunity to solve many of the problems by using robots in all situations where the risk for the operator, whether it is caused by not knowing the potential level of exposure, or where the exposure would be prohibitively high, can be reduced or completely avoided. In this paper, proof of concept for a robot, constructed for in situ localization of the contamination and consequent decontamination and a protocol for its operation, is presented. A real robot with a localization capability was constructed and its performance tested in a simulated contamination event. The idea for the upgrade of the robot adding a decontamination capability is presented also.

AB  - Tritium, hydrogen isotope, with a half-life of 12.3 years, is produced in two ways: naturally and artificially. Naturally, tritium is generated through the interaction of cosmic radiation protons and neutrons with gases in the upper atmosphere. Artificially, tritium origins from the atmospheric nuclear tests, production from nuclear reactors, future fusion reactors, fuel reprocessing plants, heavy water production facilities and commercial production for medical diagnostics, radiopharmaceuticals, luminous paints. Elevated concentrations of tritium in the environment are of great public concern. Considering the fact that nuclear power plants are located on rivers, knowing the activity concentration of this isotope in rivers is of great importance. This work presents the results for tritium determination in Danube and Sava River in Belgrade, Serbia. The origin of tritium was estimated using a mathematical parameter, symmetrical index.

AB  - This study deals with the design of the checkpoint system for monitoring the environmental radioactivity in the vicinity of the nuclear reactors. As the design site was selected the Vinča Institute of Nuclear Sciences in the capital city of the Republic of Serbia. There are situated two former nuclear research reactors with potential hazardous materials in controlled conditions. Due to the high risk of ecosystem contamination in the vicinity of various nuclear facilities such as reactor, radiological analyses of coastal soils, sediments and stream/river water were performed at the selected checkpoints. The investigation included determination of gross alpha and gross beta activities, gamma spectrometric analysis and analysis of 90Sr content in the collected environmental samples, as well as determination of 3H activity concentration, but only in water samples. Gross alpha activity ranged from 0.013 Bq/L to 0.057 Bq/L for water samples, from 130 Bq/kg to 280 Bq/kg for soil samples, and from 120 Bq/kg to 270 Bq/kg for sediment samples. Gross beta activity ranged from 0.128 Bq/L to 0.332 Bq/L for water samples, from 850 Bq/kg to 1600 Bq/kg for soil samples, and from 660 Bq/kg to 1200 Bq/kg for sediment samples. The main contribution to gamma radiation in water samples was made by 40K and 137Cs. The 226Ra/238U ratio ranged from 0.37 to 1.24 in soil and from 0.51 to 1.16 in sediment. 90Sr and 3H were detected in all studied samples. The presented results and the increased radiation risk in the above mentioned area show that the surrounding of the nuclear reactors and the exposure of the population to ionizing radiation must be constantly monitored.

AB  - This study provides insight into benefits of thermo-chemical conversion of coal slag as recovery process into value-added products. This research involves kinetic analysis of process conducted through non-isothermal thermal analysis measurements, with additional raw material characterization. Kinetic results showed that decomposition proceeds through two consecutive reactions steps (first one, including anorthite P1‾ → I1‾ phase transition, and then production of incongruent melting product (ternary system: CaO⋅Al2O3⋅2SiO2 (CAS2), where viscosity of slag changes), and second one including dehydration and formation of meta-muscovite, and subsequently, thermal disruption of muscovite de-hydroxylated phase, which proceeds with breaking of octahedral Al–O bonds), and one single-step reaction (attributed to CO-reduction of hematite to magnetite). Thermodynamic results showed an existence of physically meaningful isokinetic temperature (Tiso), which corresponds to active vibrational frequency of surroundings of SiO2 reaction site, manifested through Si‒O bond weakening by catalytic reaction of freed hydroxide ion (OH􀀀 ). It was concluded that at temperature T = Tiso, the course of process loses its dependence on temperature and pressure, regulating changes between thermodynamic parameters, through enthalpy-entropy compensation (EEC) effect.

AB  - he knowledge about behavior of 90Sr in environment is of importance to prevent and control contamination. A large number of analytical methods have been developed for the determination of 90Sr in environmental samples. The conducted study was focused on interpretation and evaluation of the results obtained using three radiochemical procedures for the separation of 90Sr and/or 90Y including the classical procedures based on a series of semi-selective precipitations, the ion-exchange procedure and the use of fuming nitric acid. The acquired results showed a good agreement between the compared methods within the terms of accuracy and precision.

AB  - This work examined the possibilities and limitations of model-free and model-based methods related to decrypting the kinetic complexity of multi-step thermo-oxidative degradation processes (as a testing system, a [4-(hydroxymethyl)phenoxymethyl] polystyrene resin was used), monitored by thermal analysis (TGA-DTG-DTA) techniques. It was found that isoconversional methods could successfully determine the correct number of process stages and presence of multiple reactions based on derived Ea(α) profiles and identify the negative dependence of the rate constant on the temperature. These methods could not overcome the problem that arose due to mass transfer limitations. The model-based method overcame more successfully the problem associated with mass transfer because its calculation machinery had capabilities for the correct solution of the total mass balance equation. However, a perfect fit with the experimental data was not achieved due to the dependence on the thermal history of the contribution (ctb.) of a given reaction step inside a fitting procedure cycle. On the other hand, through this approach, it was possible to estimate the rate-controlling steps of the process regarding the influence of the heating rate. It was found that for consecutive reaction mechanisms, the production of benzaldehyde and gases in high yields was controlled by the heating rate, where low heating rates were strongly recommended (≤10 K/min). Also, it was shown that the transport phenomenon may be also the rate-determining step (within the set of “intrinsic” kinetic parameters). It was also established that external heat transfer controls the overall rate, where the “pure” kinetic control regime had not been reached but was approached when lowering the temperature and size of the resin particles.

AB  - The aim of this study is to explain the consequences of the occurrence of enthalpy–entropy compensation (EEC) and isoequilibrium relationship during slow pyrolysis of cigarette butt filters (CBFs), consisting cellulose acetate (AC) as the main component. By using model-free and model-based kinetic methods and thermodynamic calculations, the complete reaction mechanism and extrathermodynamic issues about investigated process are completely resolved. It was established that compensation phenomenon where isoequilibrium temperature occurs is a consequence of formation of low-entropy molecular structure (cellulose II) and breaking of hydrogen bonds. Consequently, it was concluded that mechanisms which include a formation of low-entropy molecular structure and H-bonds breakage enter the changes in both enthalpy and entropy, which compensate each other. For the cellulose II generation, it was necessary to invest energy which represents use up energy. This “wasted” energy turns into work for creation of cellulose II molecular structures, whereby additional energy was provided from “local” decomposition reactions (which were identified in the established process mechanism) that arise from pyrolysis of starting material. Therefore, it was concluded that for “local reactions”, a negative ΔS° value was identified, but for the global process, the entropy change retained a positive value. Considering thermodynamic effects manifested through compensation temperature found below glass transition temperature (Tg) in the undercooling conditions, it was concluded that small amounts of plasticizers affect reduction of free volume in the glassy state. Obtained results indicated a decrease in β-relaxation mode of cellulose acetate by an abatement of the polymer free volume.

AB  - The radioactive fission product 90Sr has a sufficient half-life (28.8 years) to be detected long after its appearance in the environment. After its uptake into the soil-edible plant system, it enters the food chain and represents a potential source of contamination that threatens human health. Due to these facts, tracking the distribution of the artificial radionuclide 90Sr in the soil–edible plant system is a subject of intense research. The tracking of the 90Sr radionuclide distribution in the soil profile, as well as in the crops on the long-term experimental fields was carried out using beta radiation spectrometry. The radiochemical analytical method was used to analyze the 90Sr content in cultivated soil and crops. The conducted study focused on the experimental substantiation of the developed model for predicting the behavior of 90Sr in the cultivated soil–crop system. The results of using the applied radioecological model for the transfer of 90Sr from the soil to the above-ground part of crops showed a relatively good agreement with the experimentally determined values of the soil–crop transfer factor, which indicates that the used model can be successfully applied for the prediction of the behavior of 90Sr in the soil–soil solution–crop system.

AB  - Poslednjih nekoliko decenija sve se već i značaj pridaje iskorišć avanju otpadnih materijala koji se uz adekvatnu modifikaciju koriste u cilju izdvajanja različitih polutanata iz industrijskih otpadnih voda. Korišćenje otpadnog materijala iz jedne industrije za rešavanje problema zagađenja u drugoj industriji ultimativno vodi ka održivim i cirkularnim pristupima u inženjerstvu životne sredine. Na ovaj način, u jednom koraku mogu se rešiti dva goruć a problema, upravljanje otpadom i tretman otpadnih voda. Trend prenamene industrijskog otpada kao prekursora za formiranje sorbenata koji bi imali širok spektar primene je evidentan. Crveni mulj često se naziva nusproizvodom koji nastaje tokom proizvodnje aluminijuma. Ovaj boksitni ostatak se sve više posmatra kao resurs sa potencijalom za korisnu ponovnu upotrebu, umesto da se strogo označava kao otpad. Najčešći vid odlaganja ove visoko alkalne suspenzije jeste deponovanje na posebnim lokacijama čime se zauzimaju velike površine tla, a moguća je i migracija razli čitih potencijalno toksičnih materija u medijume voda-vazduh-zemljište. Zbog visoke alkalnosti i moguć eg ispiranja teških metala, njegovo odlaganje može biti opasno po životnu sredinu. Jedna od potencijalnih upotreba crvenog mulja, s obzirom na njegov specifičan hemijsko-mineraloški sastav, je u tretmanu industrijskih otpadnih voda u cilju uklanjanja polutanata.

AB  - In the last few decades, increasing importance has been placed on waste materials utilization with the necessary modification in order to extract various pollutants from industrial wastewater. Using the waste material from one industry to solve the pollution problem in another industry ultimately leads toward sustainable and circular approaches in environmental engineering. In this way, two pressing problems, waste management and wastewater treatment, can be solved in one step. The trend of repurposing industrial waste as a precursor for the formation of sorbents that would have a wide range of applications is evident. Red mud is often referred to as a byproduct generated during the production of alumina. This bauxite residue is increasingly being viewed as a material with the potential for beneficial reuse rather than being labeled strictly as waste. The most common type of this highly alkaline suspension disposal is deposition at special sites, which occupies large areas, and the migration of various potentially toxic substances in the water-air-soil medium is possible. Due to its high alkalinity and possible leaching of heavy metals, its disposal can be hazardous to the environment. One of the potential uses of red mud, given its specific chemical-mineralogical composition, is in the treatment of industrial wastewater in order to remove pollutants. Based on the literature review, this study summarizes the red mud’s potential usage as an adsorbent for industrial wastewater treatment, emphasizing techno-economic analysis and pollution removal efficiency. An overview of existing research includes a critical evaluation of the adsorption performance, factors influencing efficiency rather than efficacy, and the potential for specific pollutant removal such as heavy metals and radionuclides from aqueous solutions. This review provides a new approach to a circular economy implementation in wastewater treatment while guiding future research directions for sustainable and cost-effective solutions.

abstract = "Poslednjih nekoliko decenija sve se već i značaj pridaje iskorišć avanju otpadnih materijala koji se uz adekvatnu modifikaciju koriste u cilju izdvajanja različitih polutanata iz industrijskih otpadnih voda. Korišćenje otpadnog materijala iz jedne industrije za rešavanje problema zagađenja u drugoj industriji ultimativno vodi ka održivim i cirkularnim pristupima u inženjerstvu životne sredine. Na ovaj način, u jednom koraku mogu se rešiti dva goruć a problema, upravljanje otpadom i tretman otpadnih voda. Trend prenamene industrijskog otpada kao prekursora za formiranje sorbenata koji bi imali širok spektar primene je evidentan. Crveni mulj često se naziva nusproizvodom koji nastaje tokom proizvodnje aluminijuma. Ovaj boksitni ostatak se sve više posmatra kao resurs sa potencijalom za korisnu ponovnu upotrebu, umesto da se strogo označava kao otpad. Najčešći vid odlaganja ove visoko alkalne suspenzije jeste deponovanje na posebnim lokacijama čime se zauzimaju velike površine tla, a moguća je i migracija razli čitih potencijalno toksičnih materija u medijume voda-vazduh-zemljište. Zbog visoke alkalnosti i moguć eg ispiranja teških metala, njegovo odlaganje može biti opasno po životnu sredinu. Jedna od potencijalnih upotreba crvenog mulja, s obzirom na njegov specifičan hemijsko-mineraloški sastav, je u tretmanu industrijskih otpadnih voda u cilju uklanjanja polutanata. Na osnovu pregleda literature, ova studija sumira potencijalnu upotrebu crvenog mulja kao adsorbenta za prečišć avanje industrijskih otpadnih voda, naglašavajuć i tehno-ekonomsku analizu i efikasnost otklanjanja zagađenja.

AB  - The nuclear industry generates significant radioactive waste (RW) amounts, with its safe disposal being a primary safety and environmental issue. RW management involves solidification and disposal, often in deep underground facilities. Cement mortar is commonly used for liquid RW solidification due to its cost-effectiveness and simplicity. However, Portland cement concrete production raises environmental concerns, such as CO2 emissions and natural resource depletion. Additionally, RW storage and disposal costs drive research into low-cost matrices, especially those made from final waste products. The main requirements for matrix materials for liquid RW immobilization, which accept the role of primary barrier, are compatibility with RW material, good mechanical properties, and resistance to chemical and biological agents. However, partially substituting cement with waste materials can reduce strength and durability, increase susceptibility to cracking, porosity, and corrosion, further leading to harmful substance release. The matrix material must demonstrate longterm stability under various environmental conditions, including changes in temperature, humidity, and exposure to radiation ensuring that RW remains stable and safe within the matrix for decades or centuries. In addition, factors such as groundwater infiltration and seismic activity should also be considered when evaluating the long-term effectiveness of a protective structure. To manage these hazards, the selection, treatment, and preparation of recycled waste are crucial, alongside with proper design and utilization of such concrete. Monitoring concrete performance over time and implementing maintenance measures are necessary to ensure the long-term durability and reliability of structures. This work aims to assess the overall impact of recycled materials utilized in liquid RW solidification matrix.

AB  - Radiotherapy affects not only malignant, but also a healthy tissue adjacent to tumor by increasing reactive oxygen species generation, with consequent damage to biomolecules, such as the oxidation of membrane lipids, known as lipid peroxidation. The end product of lipid peroxidation is malondialdehyde. Radioprotectors are compounds that could significantly protect normal cells from radiation, without changing the tumor cell radiosensitivity. Synthetic radioprotectors usually have side effects and are toxic. Natural radioprotectors exert protection without adverse effects. In this study, we examined the radioprotective ability of linden honey in rat blood, by detecting alterations in the activities of antioxidant enzymes catalase and glutathione peroxidase and malondialdehyde concentration after the exposure to a therapeutic dose of gamma rays. Sixteen rats were randomly divided into Control and Honey groups. Honey group received honey (1.5 mL(kgd-1)) orally for four weeks, while at the same time Control group were given distilled water. After four weeks, blood was sampled from all animals. Samples were halved, and one series of samples were gamma irradiated (2 Gy). Radiation induced decreased glutathione peroxidase activity and increased malondialdehyde level, while honey treatment attenuated those alterations, keeping glutathione peroxidase and malondialdehyde at physiological levels. These findings confirm radioprotective properties of linden honey.

AB  - Nanoparticles (NPs), a distinct class of particles ranging in size from 1 to 100 nm, are one of the most promising technologies of the 21st century, and titanium dioxide NPs (TiO2 NPs) are among the most widely produced and used NPs globally. The increased application of TiO2 NPs raises concerns regarding their global safety and risks of exposure. Many animal studies have reported the accumulation of TiO2 NPs in female reproductive organs; however, evidence of the resultant toxicity remains ambiguous. Since the surface area and chemical modifications of NPs can significantly change their cytotoxicity, we aimed to compare the toxic effects of pristine TiO2 powder with surface-modified TiO2 powders with salicylic acid (TiO2/SA) and 5-aminosalicylic acid (TiO2/5-ASA) on the ovaries, oviducts, and uterus on the 14th day following acute oral treatment. The results, based on alterations in food and water intake, body mass, organ-to-body mass ratio, hormonal status, histological features of tissues of interest, and antioxidant parameters, suggest that the modification with 5-ASA can mitigate some of the observed toxic effects of TiO2 powder and encourage future investigations to create NPs that can potentially reduce the harmful effects of TiO2 NPs while preserving their positive impacts.

The results, based on alterations in food and water intake, body mass, organ-to-body mass ratio, hormonal status, histological features of tissues of interest, and antioxidant parameters, suggest that the modification with 5-ASA can mitigate some of the observed toxic effects of TiO2 powder and encourage future investigations to create NPs that can potentially reduce the harmful effects of TiO2 NPs while preserving their positive impacts.",

AB  - Introduction  Photodynamic therapy (PDT) has gained significant attention due to its superiority over conventional treatments. In the context of skin cancers and nonmalignant skin diseases, topical application of photosensitizer formulations onto affected skin, followed by illumination, offers distinct advantages. Topical PDT simplifies therapy by providing easy access to the skin, increasing drug concentration within the target area, and confining residual photosensitivity to the treated skin. However, the effectiveness of topical PDT is often hindered by challenges such as limited skin penetration or photosensitizer instability. Additionally, the hypoxic tumor environment poses further limitations. Nanocarriers present a promising solution to address these challenges. Areas covered  The objective of this review is to comprehensively explore and highlight the role of various nanocarriers in advancing topical PDT for the treatment of skin diseases. The primary focus is to address the challenges associated with conventional topical PDT approaches and demonstrate how nanotechnology-based strategies can overcome these challenges, thereby improving the overall efficiency and efficacy of PDT. Expert opinion  Nanotechnology has revolutionized the field of PDT, offering innovative tools to combat the unfavorable features of photosensitizers and hurdles in PDT. Nanocarriers enhance skin penetration and stability of photosensitizers, provide controlled drug release, reduce needed dose, increase production of reactive oxygen species, while reducing side effects, thereby improving PDT effectiveness.

AB  - Different organic compounds in aquatic bodies have been recognized as an emerging issue in Environmental Chemistry. The gamma irradiation technique, as one of the advanced oxidation techniques, has been widely investigated in past decades as a technique for the degradation of organic molecules, such as dyes, pesticides, and pharmaceuticals, which show high persistence to degradation. This review gives an overview of what has been achieved so far using gamma irradiation for different organic compound degradations giving an explanation of the mechanisms of degradations as well as the corresponding limitations and drawbacks, and the answer to why this technique has not yet widely come to life. Also, a new approach, recently presented in the literature, regards coupling gamma irradiation with other techniques and materials, as the latest trend. A critical evaluation of the most recent advances achieved by coupling gamma irradiation with other methods and/or materials, as well as describing the reaction mechanisms of coupling, that is, additional destabilization of molecules achieved by coupling, emphasizing the advantages of the newly proposed approach. Finally, it was concluded what are the perspectives and future directions towards its commercialization since this technique can contribute to waste minimization i.e. not waste transfer to other media. Summarizing and generalization the model of radiolytic degradation with and without coupling with other techniques can further guide designing a new modular, mobile method that will satisfy all the needs for its wide commercial application.

AB  - The Ti−45Nb (wt.%) alloy properties were investigated in relation to its potential biomedical use. Laser surface modification was utilized to improve its performance in biological systems. As a result of the laser treatment, (Ti,Nb)O scale was formed and various morphological features appeared on the alloy surface. The electrochemical behavior of Ti−45Nb alloy in simulated body conditions was evaluated and showed that the alloy was highly resistant to corrosion deterioration regardless of additional laser surface modification treatment. Nevertheless, the improved corrosion resistance after laser treatment was evident (the corrosion current density of the alloy before laser irradiation was 2.84×10−8 A/cm2, while that after laser treatment with 5 mJ was 0.65×10−8 A/cm2) and ascribed to the rapid formation of a complex and passivating bi-modal surface oxide layer. Alloy cytotoxicity and effects of the Ti−45Nb alloy laser surface modification on the MRC-5 cell viability, morphology, and proliferation were also investigated. The Ti−45Nb alloy showed no cytotoxic effect. Moreover, cells showed improved viability and adherence to the alloy surface after the laser irradiation treatment. The highest average cell viability of 115.37% was attained for the alloy laser-irradiated with 15 mJ. Results showed that the laser surface modification can be successfully utilized to significantly improve alloy performance in a biological environment.

AB  - This paper presents a study and comparison of surface effects induced by picosecond and nanosecond laser modification of a Ti6Al4V alloy surface under different ambient conditions: air and argon- and nitrogen-rich atmospheres. Detailed surface characterization was performed for all experimental conditions. Damage threshold fluences for picosecond and nanosecond laser irradiation in all three ambient conditions were determined. The observed surface features were a resolidified pool of molten material, craters, hydrodynamic effects and parallel periodic surface structures. Laser-induced periodic surface structures are formed by multi-mode-beam nanosecond laser action and picosecond laser action. Crown-like structures at crater rims are specific features for picosecond Nd:YAG laser action in argon-rich ambient conditions. Elemental analysis of the surfaces indicated nitride compound formation only in the nitrogen-rich ambient conditions. The constituents of the formed plasma were also investigated. Exploring the impact of process control parameters on output responses has been undertaken within the context of laser modification under different environmental conditions. Parametric optimization of the nanosecond laser modification was carried out by implementing an advanced method based on Taguchi’s parametric design and multivariate statistical techniques, and optimal settings are proposed for each atmosphere.

The grain size reduction from 2.76 μm to ~ 200 nm and the appearance of laser-induced morphologically altered and highly oxidized surface led to the significant improvement of alloy corrosion resistance and cell–implant interaction. Moreover, an additional increase of the laser pulse energy from 5 to 15 mJ during the alloy irradiation in the air led to an increase in the surface oxygen content from 13.64 to 23.89% accompanied by an increase of excellent cell viability from 127.18 to 134.42%. As a result of the controlled alloy microstructural and surface modifications, the formation of protective bi-modal mixed Ti- and Nb-oxide external scale was enabled. The presence of this surface oxide scale enhanced the alloy’s resistance to corrosion deterioration and simultaneously boosted cell viability and proliferation.

AB  - Mechanical properties and structure-property relationship of the Ti-45Nb (mass%) alloy with potential applications in biomedicine were investigated using a multidisciplinary approach. Because the biomechanical compatibility of metallic implant materials can be significantly improved by microstructural refinement and laser surface modification (LSM), the present study concentrates on the investigation of the mechanical properties of the Ti-45Nb alloy subjected to extreme processing conditions to evaluate their impact on the alloy improved applicability in the bio-environment. The alloy was therefore subjected to high-pressure torsion (HPT) and LSM processing to obtain favorable alloy characteristics. Crystal structure prediction was conducted using data mining (DM) and evolutionary algorithms (EA). All the obtained potential structure candidates were submitted to the local optimizations at the level of density functional theory (DFT); subsequently, the phonon lattice dynamics and mechanical properties were systematically investigated. The alloy structure progression and mechanical characteristics were examined under the influence of extremely high temperatures induced during the LSM processing and the extreme pressure achieved during the HPT treatment. XRD characterization was performed using experimental and theoretical methods showing the presence of bcc β-Ti and orthorhombic Cmcm Ti4Nb phase. Mechanical properties such as Young's modulus, Vicker's hardness, and plasticity of the most relevant Ti4Nb modifications predicted after DM-EA-DFT were found to corroborate well with the experimental results of nanoindentation measurements. The present study reveals that the additional processing of the Ti-45Nb alloy under extreme conditions leads to significant improvement in the alloy's bio-mechanical compatibility.
