AB  - Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the air
atmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessed
using UV/Vis DR spectroscopy, structural and morphological parameters of two materials are
obtained using XRD, TEM, and FTIR. Flat-band potentials were determined from Mott-Schottky
plots, and combined with corresponding band-gap energies, to estimate conduction and valence
band potentials of both materials. Photocatalytic efficacy of both semiconductors in photocatalytic
degradation of three textile dyes under simulated solar light irradiation is compared, with the
conclusion that n-C3N4 expressed higher photocatalytic ability in the studied systems. Finally, in
order to provide reusability of the semiconductors in multiple consecutive photocatalytic cycles,
both photocatalysts were drop-coated on the jute-based post industrial waste. Reusability of juten-C3N4 material is probed in three consecutive photocatalytic cycles, and the obtained results
showed that this material can have a future in solving real-life environmental problems.

AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

AB  - Intensified oil exploitation accompanied with frequent oil spills having a detrimental impact on ecosystems are seeking efficient, environmentally and economically feasible solutions. In an attempt to develop an efficient, reusable, biodegradable and cheap sorbent for oil clean-up non-woven sorbents based on recycled jute post-industrial textile waste were fabricated. The influence of area density of non-woven sorbents and hydrophobicity of fibers on overall oil sorption performance was the focus of this research. All sorbents showed a good reusability after five sorption cycles and buoyancy in water even after 24 h independently of sorbent structure. The area density of sorbents and viscosity of studied oils (crude oil, diesel oil and two types of motor oils) highly affected the oil sorption capacity and oil retention. The sorbent with the lowest area density exhibited the best oil sorption performance. The esterification of jute with stearic fatty acid contributed to decrease in water uptake of sorbents but also to negligible change of oil sorption behavior indicating that the structure of the sorbent in this case plays a crucial role.

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  - Polyaniline (PANI) is a promising conducting polymer for surface modification and sensitizing of TiO2 to achieve extended photoresponse to visible light and increased photocatalytic efficiency [1]. Reducing the level of e-/h+ recombination in TiO2 and photosensitized properties of PANI was the basis for creation of new functional PANI/TiO2 nanocomposites. Carbonization process additionally contribute improving photoactivity of TiO2 due to formation of new structures. Namely, after carbonization process of PANI component, graphene-like structures are formed [2]. On the other hand, temperature treatment during carbonization caused appearance of rutile beside anatase crystal structure of TiO2, so combination of mentioned crystal phases induced better photocatalytic activity. In this study, we report the synthesis of a carbonized PANI/TiO2composite with different initial weight ratios of PANI, which was subsequently employed for photocatalytic degradation of methylene blue (MB), Rhodamine B (RB) and Acid Orange 7 (AO7) under white-light irradiation. Molecular and crystal structure, morphology, and photocatalytic response of the synthesized nanocomposite were characterized by Raman spectroscopy, XRD measurements, field-emission scanning electron microscopy, and UV visible spectroscopy, respectively. Obtained results showed significant enhance of photocatalytic properties of synthesized nanocomposites in comparison to neat titania nanotubes.

AB  - Removal of the β-blocker atenolol from an aqueous solution was studied using TiO2/zeolites, prepared by a simple and cost-effective solid-state dispersion method. Synthetic zeolites 13X and ZSM-5 (Si/Al = 40) and natural zeolite clinoptilolite were used as one component of the hybrid materials, whereas TiO2 nanocrystals obtained from TiO2 nanotubes and P25 TiO2 nanoparticles were used as the other. The synthesized materials were characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transformed infrared spectroscopy, ultraviolet–visible diffuse reflectance spectroscopy and scanning electron microscopy with energy-dispersive spectroscopy. The photocatalytic activity for the degradation of atenolol was investigated under simulated solar light. Additionally, the effect of initial pH on atenolol removal and the reusability of prepared catalysts were tested. The best loading of TiO2 was 20 wt% over all investigated zeolites. The degradation of atenolol followed the pseudo-first-order kinetics. The photocatalytic degradation of atenolol after 70 min of irradiation was ~ 50% for TiO2/13X materials, ~ 45% for clinoptilolite combined with P25 TiO2 and ~ 57% for clinoptilolite combined with TiO2 nanocrystals obtained from TiO2 nanotubes. The results showed the highest removal efficiency after 70 min of irradiation for ZSM-5 combined with P25 TiO2 (~ 94%), followed by ZSM-5 combined with TiO2 nanocrystals obtained from TiO2 nanotubes (~ 88%) at near-neutral pH (~ 6.5). The total removal of atenolol from an aqueous solution for TiO2/ZSM-5 materials resulted from two processes: adsorption and photocatalytic degradation. The TiO2/ZSM-5 photocatalysts can be easily recovered and reused as their activity was preserved after four cycles.

AB  - Structural, conductive and dielectric properties of hybrid Polypyrrole (PPy)-TiO2 nanocomposite-coated polyamide fabric (PA-PPy/TiO2) synthesized by in-situ oxidative polymerization of pyrrole on the surface of polyamide in the presence of colloidal TiO2 NPs (d ~ 4.5 nm) have been studied. Raman spectra confirmed salt form of PPy in both neat PPy and PPy/TiO2-coated PA fabric and indicated its complete coverage. SEM/EDX analysis confirmed presence of TiO2 NPs and changes in granular structure of PPy deposited on the surface of PA fiber depending on the amount of TiO2 NPs. The PA-PPy/TiO2 nanocomposite sample with lowest content of TiO2 NPs (6.79 At.% Ti) showed highest conductivity (~10−6 S/cm) and dissipation factor (tan δ) in the entire frequency range. The lowest amount of TiO2 NPs in the PA-PPy/TiO2 nanocomposite induced two to four orders of magnitude higher tan δ value, compared to neat PPy covered PA fabric, depending on the frequency range. Frequency dependence of real (ϵ′) and imaginary part (ϵ″) of the complex permittivity for neat PA and PPy/TiO2-coated PA fabrics follow the trend of changes in dissipation factor for the same TiO2 NPs concentrations. The presence of TiO2 NPs could be exploited for tuning the conductive and dielectric properties of a conductive layer.

The PA-PPy/TiO2 nanocomposite sample with lowest content of TiO2 NPs (6.79 At.% Ti) showed highest conductivity (~10−6 S/cm) and dissipation factor (tan δ) in the entire frequency range. The lowest amount of TiO2 NPs in the PA-PPy/TiO2 nanocomposite induced two to four orders of magnitude higher tan δ value, compared to neat PPy covered PA fabric, depending on the frequency range. Frequency dependence of real (ϵ′) and imaginary part (ϵ″) of the complex permittivity for neat PA and PPy/TiO2-coated PA fabrics follow the trend of changes in dissipation factor for the same TiO2 NPs concentrations. The presence of TiO2 NPs could be exploited for tuning the conductive and dielectric properties of a conductive layer.",

AB  - TiO2 prolatenanospheroids (PNSs) may be photosensitizers (PSs), which act by catalyzation of hydroxyl radical (∙OH) formation upon light illumination. ∙OH might, in turn, contribute to killing of cancer cells. On the other hand, there is great concern about toxicity in the dark of TiO2 nanoparticles in general. In this work, we have investigated the biocompatibility of TiO2 PNSs of the anatase crystal form (length between 100 and 300 nm and width 50 nm) in the dark with immune cells and light-induced cytotoxicity on several cancer cell lines. The effects of the treatment of different cell lines with several concentrations of TiO2 PNSs suspensions showed the specifics of cells’ viability and the intracellular localization. The results of in vitro studies obtained by cytotoxicity assays adjusted to individual cell lines’ metabolism point towards the biocompatibility of TiO2 PNSs at low and moderate concentrations in the dark, which neither kill the cells, nor induce activation of the immune system cells. Laser scanning confocal microscopy revealed that PNSs are taken up by cells, and insight into the intracellular distribution was obtained in this study.

AB  - This work presents a new multilayered microfluidic platform, manufactured using a rapid and cost-effective xurography technique, for the detection of drug concentrations in sweat. Textile fabrics made of cotton and polyester were used as a component of the platform, and they were positioned in the middle of the microfluidic device. In order to obtain a highly conductive textile, the fabrics were in situ coated with different amounts of polyaniline and titanium dioxide nanocomposite. This portable microfluidic platform comprises at least three layers of optically transparent and flexible PVC foils which were stacked one on top of the other. Electrical contacts were provided from the edge of the textile material when a microfluidic variable resistor was actually created. The platform was tested in plain artificial sweat and in artificial sweat with a dissolved cytostatic test drug, cyclophosphamide, of different concentrations. The proposed microfluidic device decreased in resistance when the sweat was applied. In addition, it could successfully detect different concentrations of cytostatic medication in the sweat, which could make it a very useful tool for simple, reliable, and fast diagnostics.

AB  - This research paper focuses on doped TiO2  nanocrystals of different shape, size and structures, in addition to nanocomposites consisting of TiO2  nanocrystals and conductive polymers (Polyaniline (PANI)). The primary objective of this research paper is to ensure understanding of the influence of size, shape, structure and doping level on optical and magnetic properties of TiO2  nanoparticles, as well as the interaction between nanoparticles and PANI due to the creation of desired photocatalytic properties of nanocomposites. The doping of TiO2  nanocrystals with rare earth ions opens up the possibility of controlling their optical properties. The Sm3+ doped TiO2  faceted nanocrystals exhibited red photoluminescence, associated with 4 G5/2-6 HJ  (J=5/2, 7/2 and 9/2) f–f transitions of Sm3+ in the 4f5  configuration, after band-to-band excitation, confirming the accomplishment of energy transfers. The Ni2+ doped TiO2  nanocrystals enabled the synthesis of optically transparent nanostructured films that showed room-temperature ferromagnetism with almost closed loop (HC ~ 150-200 Oe) and saturation magnetization in the range of 10-3-5x10-2 μB/Ni depending on dopant concentration. Ni2+ ions that substitute core Ti atoms were found to participate in the light excitation processes, too. The improvement of photocatalytic efficiency of TiO2  nanocrystals by surface modification with carbonized form of PANI was tested in degradation processes of Rhodamine B and Methylene blue. The carbonized PANI/TiO2  nanocomposites showed significantly higher photocatalytic efficacy compared to the bare TiO2 and the non-carbonized PANI/TiO2  nanocomposites. Their photocatalytic activity is influenced by their surface and crystalline structures, absorption coefficient in the visible part of the spectrum, high mobility of charge carriers and finally by the molecular structures of the organic dyes used.

Испитивања утицаја величине, облика, структуре и нивоа допираности наночестица ТiО2  на њихове оптичке, магнетне и фотокаталитичке особине, као и разумевање интеракције наночестица и полимерне матрице (ПАНИ) у циљу креирања нанокомпозита одговарајућих фотокаталитичких својстава представљају главне правце овог истраживања. Обзиром на структуру енергетског процепа наночестица TiO2 , допирање јонима ретких земаља отвара могућност за контролу њихових оптичких карактеристика.

Допирање наночестица TiO2  јонима Ni2+ отвара могућност за синтезу транспарентних наноструктурних филмова који показују феромагнeтно уређење на собној температури (HC ~ 150-200 Oe) и сатурациону магнетизацију у опсегу 10-3- 5x10-2 μB/Ni, у зависности од концентрације допанта. Следећи циљ ових истраживања био је повећање фотокаталитичке ефикасности/активности наночестица TiO2  површинском модификацијом проводним ПАНИ полимером у карбонизованој форми, уз дефинисање механизма процеса фотокаталитичке деградације модел молекула метиленско плавог (Methylene blue) и родамина Б (Rhodamine B). У поређењу са немодификованим наночестицама TiO2 , ПАНИ/TiO2  нанокомпозити, ексцитовани белом светлошћу, показали су значајно већу фотокаталитичку ефикасност. Процес карбонизације полианилина у ПАНИ/TiO2  нанокомпозитима је довео до даљег повећања њихове фотокаталитичке ефикасности. Фотокаталитичка активност нанокомпозита је условљена њиховом површинском структуром, високом мобилношћу носилаца наелектрисања и апсорпционим коефицијентом полианилина у видљивом делу спектра, као и молекулском структуром испитиваних боја.

AB  - Hydrothermal synthesis of Mn2+ doped titanate nanotubes (TNTs), which exhibited room temperature ferromagnetism (RTFM), is reported. Dispersions of 1 and 5 at.% Mn2+ doped anatase TiO2 nanocrystals were used as precursors. Size and shape of Mn2+ doped TNTs and precursor nanocrystals were studied by transmission electron microscopy (TEM). The relatively uniform size distribution of transverse dimension of nanotubes of about 10 nm was observed while their lengths varied up to few hundred nanometers. The X-Ray Diffraction (XRD) analysis and Raman spectroscopy of resultant powder confirmed the hydrogen dititanate (H2Ti2O5 x H2O) crystal phase of Mn2+ doped TNTs with the presence of small amount of sodium titanates. Electron paramagnetic resonance (EPR) experiments were performed to probe the local atomic and electronic structure of Mn in the nanotubes. Room temperature ferromagnetic ordering with saturation magnetic moment (Ms) in the range of 0.6–1.5 μB per Mn atom was observed. © 2019 Elsevier Masson SAS

The relatively uniform size distribution of transverse dimension of nanotubes of about 10 nm was observed while their lengths varied up to few hundred nanometers. The X-Ray Diffraction (XRD) analysis and Raman spectroscopy of resultant powder confirmed the hydrogen dititanate (H2Ti2O5 x H2O) crystal phase of Mn2+ doped TNTs with the presence of small amount of sodium titanates. Electron paramagnetic resonance (EPR) experiments were performed to probe the local atomic and electronic structure of Mn in the nanotubes. Room temperature ferromagnetic ordering with saturation magnetic moment (Ms) in the range of 0.6–1.5 μB per Mn atom was observed. © 2019 Elsevier Masson SAS",

AB  - There has been a growing demand for development and improvement of cancer treatment in order to overcome disadvantages and limitations of traditional chemotherapy such as resistance, toxicity, and activity against a small number of tumor types. Photodynamic therapy is a rapidly developing cancer treatment that utilizes the combination of photoactive drug and/or carrier and light as an external stimulus to destroy tumors, achieve a maximum concentration of the drug on tumor site, reduce side effects of drug onto the healthy tissue, enable dosage control, and more effective treatment which could improve outcome of therapy [1]. We investigated possibility to use ТiО2 nanoparticles as a carrier for potential antitumor drug [Ru(II)(dcbpy)2Cl2], cis-dichlorobis (2, 2'-bipyridyl-4, 4'-dicarboxylicacid) ruthenium(II). Nanocomposite system has been formed by binding of ruthenium complex to the ТiО2 nanoparticles. Components of the system are selected according to their preferences, such as biocompatibility, photo activity, and easy surface modification for ТiО2, and less toxicity, significant activity against cancer metastases, and activity on tumors that were resistant to a variety of standard chemotherapeutic agents for Ru-complexes. Both components of the system are also photoactive, therefore potential for system manipulation and use in photodinamic therapy has been investigated by irradiation with UV and visible light. Additionally, the feasibility of using this system as a light-triggered drug delivery system was shown on amelanotic melanoma cancer line. The experimental results revealed a potential of nanocomposite system for long-term constant release of complex which is suitable for clinical practice. The further investigation of nanocomposite system indicated that it exhibited UV and red light susceptible drug release behavior [2]. More precisely, the system demonstrated slower complex release upon visible and increased release rate upon UV light illumination which was also in good correlation with the light–dependent cytotoxicity of the system demonstrated on amelanotic melanoma cancer line. The melanoma cancer cell death is enhanced by UV and reduced by red light in the presence of investigated nanocomposite system [3]. All obtained results suggested that nanocomposite system may have a potential use as a light sensitive drug delivery system in photodynamic therapy which could significantly contribute to development of more efficient and less invasive therapy of melanoma which is highly aggressive and deadliest form of skin cancer.

AB  - A comprehensive study of the removal of selected biologically active compounds (pharmaceuticals and pesticides) from different water types was conducted using bare TiO2nanoparticles and TiO2/polyaniline (TP-50, TP-100, and TP-150) nanocomposite powders. In order to investigate how molecular structure of the substrate influences the rate of its removal, we compared degradation efficiency of the initial substrates and degree of mineralization for the active components of pharmaceuticals (propranolol, and amitriptyline) and pesticides (sulcotrione, and clomazone) in double distilled (DDW) and environmental waters. The results indicate that the efficiency of photocatalytic degradation of propranolol and amitriptyline was higher in environmental waters: rivers (Danube, Tisa, and Begej) and lakes (Moharač, and Sot) in comparison with DDW. On the contrary, degradation efficacy of sulcotrione and clomazone was lower in environmental waters. Further, of the all catalysts applied, bare TiO2and TP-100 were found to be most effective in the mineralization of propranolol and amitriptyline, respectively, while TP-150 appeared to be the most efficient in terms of sulcotrione and clomazone mineralization. Also, there was no significant toxicity observed after the irradiation of pharmaceuticals or pesticides solutions using appropriate catalysts on rat hepatoma (H-4-II-E), mouse neuroblastoma (Neuro-2a), human colon adenocarcinoma (HT-29), and human fetal lung (MRC-5) cell lines. Subsequently, detection and identification of the formed intermediates in the case of sulcotrione photocatalytic degradation using bare TiO2and TP-150 showed slightly different pathways of degradation. Furthermore, tentative pathways of sulcotrione photocatalytic degradation were proposed and discussed. Kinetics, toxicity and intermediates assessment of biologically active compounds (pesticides and pharmaceuticals) in environmental waters.

As potential medicament, we use Ru(II)(dcbpy)2Cl2complex, and in order to achieve better photosensitization properties, the Ru complex was attached to the nano carrier—TiO2nanoparticles. Additionally, this nanocomposite system was encapsulated in the phospholipid vesicles, which could be classified as small unilamellar vesicles, based on the technique of production. The complex-release tests were performed under light illumination, at pH 5, characteristic for tumor cells` interior and compared with the release pattern at pH 7, characteristic for the serum, i.e. physiological solution.

They are, on the one hand, an useful tool in advanced analytical chemistry, in particular for studying of biologically-relevant processes, but also important as functional parts of the systems designed for controlled and targeted delivery of medicaments for treatment of a variety of diseases and for imaging. So far, thousands of compounds and systems have been developed for the above-mentioned purposes, but there are only a few reviews dealing with these topics. The aim of this review is, thus, to summarize recent applications of nano-structured inorganic materials in the field of drug delivery, bioimaging and bioanalytics, and to give a prospective from the standpoint of biology-related applications.

AB  - This study discusses a novel approach for fabrication of floating photocatalyst which can be efficiently exploited for photodegradation of dyes in aqueous solutions. A fabrication of the floating photocatalyst consisted of two steps: transformation of the poly(ε-caprolactone) beads (PCLb) into poly(ε-caprolactone) foam (PCLf) with porous structure in supercritical carbon-dioxide and subsequent loading of PCLf with TiO2 nanoparticles (NPs). Morphological characterization of the PCLf before and after TiO2 NPs loading was carried out by FESEM. The presence of titanium on the surface and inside the PCLf was detected by EDX. Photocatalytical activity of the floating photocatalyst was investigated in aqueous solution of textile dyes C.I. Acid Orange 7 (AO7) and C.I. Basic Yellow 28 (BY28) which were exposed to lamp that simulates the sun light. In addition to sustainable floatability for a long period of time, developed floating photocatalyst exhibited high rate of photodegradation since the complete discoloration of AO7 and BY28 solutions and photocatalysts alone occurred after 300 and 180 min of illumination, respectively. Its photocatalytic activity was preserved after three repeated photodegradation cycles with unchanged chemical structure that was confirmed by FTIR analysis.

AB  - The fabrication of antimicrobial textile nanocomposite by in situ synthesis of Cu-based nanoparticles on cotton fabrics modified with different polycarboxylic acids was discussed in this study. In order to evaluate the influence of carboxyl group content on Cu2+-ions adsorption, their subsequent reduction with sodium borohydride and formation of Cu-based nanoparticles, cotton fabrics were modified with succinic, citric and 1,2,3,4-butanetetracarboxylic acids. It was shown that the larger the number of carboxyl groups in applied acid, the larger the content of free carboxyl groups on the fibers and consequently, the larger the Cu2+-ions uptake and total amounts of Cu-based nanoparticles. On the basis of the XPS and XRD measurements, it was suggested that synthesized nanoparticles were mixture of Cu2O and CuO. Fabricated nanocomposites provided maximum reduction of Gram-negative bacterium E. coli and Gram-positive bacterium S. aureus and controlled release of Cu2+-ions in physiological saline solution which are necessary prerequisites for infection prevention.

AB  - This study discusses the possibility of immobilization of colloidal TiO2 nanoparticles (NPs) onto poly(ε-caprolactone) (PCL) beads and foams that could be utilized for the removal of textile dyes from water by photodegradation. PCL foams were fabricated by environmentally friendly treatment of PCL beads in supercritical carbon dioxide. PCL beads and foams loaded with colloidal TiO2 NPs were used as photocatalysts for the removal of the textile dyes C.I. Acid Orange 7 and C.I. Basic Yellow 28 from aqueous solutions (10 mg L-1) under illumination that simulated sunlight. Unlike the PCL beads, the PCL foams provided complete discoloration of the dye solution within 24 h of illumination. The PCL foams also exhibited excellent floatability that was maintained for more than four weeks. Additionally, their photocatalytic activity was preserved within three repeated photodegradation cycles, indicating that the floating photocatalyst provided superior photocatalytic activity compared to the non-floating PCL beads.

AB  - In a series researches so far, it has been shown that TiO2 nanoparticles have become the focus of intensive exploration in the field of photocatalysis, as a consequence of their unique properties and potential applications. In order to improve photocatalytic and functional properties of TiO2 nanoparticles, different methods should be used. One of the most effective approaches is capping of nobel metal (Pt, Ag, Au) clusters on nanoparticle surface. Namely, metal clusters act as electron traps and they promote interfacial charge- -transfer processes and reduce undesirable recombination processes on TiO2 nanoparticle surface.  As a consequence, photocatalytic efficiency of the system should be improved.  The cotton fabric modified by TiO2/Ag nanoparticles was synthesized by in situ photoreduction of Ag+-ions on alanine modified TiO2 colloidal nanoparticles previously deposited onto cotton fabric. Adsorption of Ag+-ions on TiO2 nanoparticle surface was improved by addition of alanine amino-acid. As a result, separation of photoinduced charges is preferred and recombination process is significantly reduced. In order to further improve the efficiency of the system, methyl alcohol was employed as hole-scavenger. Obtained results confirmed the presence of TiO2/Ag nanoparticles across the surface of cotton fabric (SEM), as well as successful fabrication of metallic Ag on investigated fabric (XRD). Interaction between alanine modified TiO2 and Ag nanoparticles was studied by FTIR, while structural properties of synthesized samples were investigated by Raman spectroscopy. The photocatalytic performance of TiO2/Ag nanoparticles modified cotton fabric was tested in the process of photodegradation of organic dyes under simulated solar light: Rhodamine B, Acid Orange 7 and Methyl Red.

AB  - In situ synthesis of Cu/Cu2O nanoparticles on the cotton fabric discussed in this study relies on adsorption of Cu2+-ions by carboxylate groups generated through the TEMPO-mediated oxidation of cellulose and their subsequent reduction by sodium borohydride. In order to establish the influence of aldehyde and carboxylate groups on the nanoparticles formation, the duration of TEMPO-mediated oxidation was varied. Chemical changes induced by TEMPO-mediated oxidation were evaluated by titrimetric determination of the amounts of aldehyde and carboxylic groups in cotton and FTIR spectroscopy. The presence of Cu/Cu2O nanoparticles on the cotton fabric was confirmed by FE-SEM, AAS and XRD analyses. Antimicrobial activity of synthesized nanoparticles was tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and fungi C. albicans. The extension of TEMPO oxidation time led to an increase of carboxylate group content and consequently, formation of larger amounts of Cu/Cu2O nanoparticles. All fabricated textile nanocomposites provided excellent antibacterial and acceptable antifungal activity. They also ensured a controlled release of Cu2+-ions in physiological solution which is an imperative for infection prevention.

The extension of TEMPO oxidation time led to an increase of carboxylate group content and consequently, formation of larger amounts of Cu/Cu2O nanoparticles. All fabricated textile nanocomposites provided excellent antibacterial and acceptable antifungal activity. They also ensured a controlled release of Cu2+-ions in physiological solution which is an imperative for infection prevention.",
