AB  - Purpose:Even though various types of scaffolds have been used lately as a complement to microfracture, the exact mechanism of reported cartilage repair improvement when using scaffolds is still unclear. In this study, an effort has been made to identify the specific effects that scaffolds may have on the cells of reparation when using this technique.Methods:A 3‑D model in vitro, representing microfracture and containing both chondrocytes and bone marrow‑derived cells in different experimental conditions was made, and the cells were cultured for eight weeks. Subse‑quently, the constructs containing our 3‑D model were removed from the cell culture medium, fixed in paraffin and analyzed with immunohistochemistry.Results:Bone marrow – derived cells migrated to the upper compartment of the construct through a perforated nylon membrane containing both enzymatically digested‑ and non‑digested particulated cartilage. The histological sections were stained with hematoxylin, eosin, S‑100, SOX‑9, Gomori, and procollagen type I and II. When minced cartilage wasn’t pretreated with collagenase, exclusively bone‑derived cells have created new extracellular matrix as showed by the histological analysis.Conclusions:In this model of microfracture, bone‑derived cells but not chondrocytes have shown to have an active role in new cartilage formation without predigestion with collagenase. Moreover, it seems that the addition of a chitosan‑based scaffold may lead to the improvement of a new cartilage matrix synthesis and integration. This effect hasn’t been seen without the use of scaffold or when a fibrin‑ or a collagen‑based scaffold have been used.

AB  - Producing green and efficient energy sources is a major challenge. As a consequence, the use of photovoltaic devices for conversion of light into electricity is growing worldwide. A lot of effort had been invested to create high-efficient solar cells, but their durability, stability, flexibility and efficiency at low light intensities are still unexplored. Here, we built a flexible solar cell made of p-doped, amorphized a-undoped and n-doped Sb2S3 solid carrier loaded with electrolyte. Indium tin oxide glass was the working electrode, and aluminium was the counter electrode. Every (p-a-n) flexible Sb2S3/solid carrier layers were obtained using a cheap casting/solvent evaporation technique, from a blend consisted of chitosan, polyethylene glycol and electrolyte containing 0.5 M potassium iodide and 0.05 M iodine, and corresponding synthesized amorphized a-undoped and p and n-doped Sb2S3 semiconductor. Results show that flexible Sb2S3 solar cell possesses good stability and efficiency of about 10% at 5% sun. Overall, our findings demonstrate for the first time that flexible solar cell can be made and used for low light intensity applications.

With spraying technique, the layers were deposited and the thickness of films was 1m. A new solid carrier of electrolyte was a blend consisted of chitosan (low MW), polyethylene glycol and electrolyte. X-ray diffraction was recorded to confirm the amorphous nature of the blend. Information about the surface appearance and roughness of a solid carrier dry and soaked in the electrolyte was given by atomic force microscopy. The solar cell was examined at very low and low light intensity (5% and 35% of sun, respectively), and at standard test conditions (100% of sun) using different light sources. The whole cell surface was 7.5cm(2) while the illuminated part was 3cm(2). Obtained results expressed for the illuminated surface showed the highest efficiency of 23.1% at 5% of sun while the efficiency of the cell was 2.9% at 35% of sun and only 0.75% at intensity of 100% of sun.

AB  - Monitoring bromides (Br-) is of crucial importance since bromates, potential human carcinogens, are formed during ozonation of water containing bromides in concentrations GT 100 mu gL(-1). Within this study, silver (Ag) and four carbon-supported Ag catalysts were synthesized by the gamma-radiation method and their morphology and structure examined using transmission electron microscopy, X-ray diffraction, and UV-Vis analysis. The nanocatalysts were tested for Br- sensing in aqueous media using cyclic voltammetry. All five Ag materials exhibited electroactivity for sensing of Br- ions, with pure Ag catalyst giving the best response to Br- ions presence in terms of the lowest limit of detection. Sensing of bromides was also explored in tap water after addition of bromides suggesting that herein prepared catalysts could be used for bromides detection in real samples. Furthermore, sensing of other halogen ions, namely, chlorides and iodides, was examined, and response due to chloride presence was recorded.

AB  - To produce well-defined metal clusters stabilized in protective matrix, poly(N-isopropylacrylamide) (PNi-PAAm) hydrogel with different initial concentration of polymer was used as nanoreactor. The in situ synthesis of well dispersed silver nanoparticles (AgNPs) was performed by gamma irradiation. The obtained AgNPs are spherical in shape with the diameter less than 20 nm. Crystalline properties of nanoparticles such as size, texture coefficient, strain, stress, lattice parameter, d-spacing, and dislocation density have been calculated using XRD data. Results confirm that the changes of lattice parameter of crystalline AgNPs sensitively reflect their state of strain and stress depending on the formation conditions (i.e., on the concentration of PNiPAAm) and on the diameter of AgNPs. The negative lattice strain and compression stress were observed for the smaller AgNPs (lattice contraction), while for the larger AgNPs are positively strained and under tensile stress (lattice expansion). XPS spectra revealed the donor-acceptor type of interaction between carbonyl oxygen from PNiPAAm and AgNPs (positive shift of high BE component of O 1s and negative shift of Ag 3d BE). The greater dislocation density of smaller AgNPs incorporated in more concentrated PNiPAAm, resulted in more binding sites and stronger interaction with polymer.

XPS spectra revealed the donor-acceptor type of interaction between carbonyl oxygen from PNiPAAm and AgNPs (positive shift of high BE component of O 1s and negative shift of Ag 3d BE). The greater dislocation density of smaller AgNPs incorporated in more concentrated PNiPAAm, resulted in more binding sites and stronger interaction with polymer.

AB  - PVA (Poly(vinyl alcohol)) matrixes were developed for potential application in electrochemical energy conversion devices, like batteries, alkaline fuel cells and electrolyzers. They were prepared by gamma-irradiation of aqueous PVA solutions, followed by different post irradiation treatments. By immersion in an electrolyte they become membranes with high ionic conductivities. The treatments were shown as the key factor determining the conductivity, through affecting their structure. An improved structure has large fractional free volume, and allows high electrolyte uptake and thus high conductivity (0.30 S cm(-1) -0.34 S cm(-1)). The structure, as well as the conductivity, has not been changed even after a period of 14 months, although the membranes have been exposed to strong alkaline medium. Besides high and long-term conductivity of the KOH doped membranes, other important properties for application in the devices were investigated, like thermal stability and gas crossover through the membranes. The 10% PVA(25kGy) membrane doped with saturated LiNO3 solution was tested in a rechargeable aqueous Li-ion battery. Due to its high conductivity it allowed an electrode material to have the same coulombic efficiency as it would have in liquid LiNO3, showing good compatibility with the material. All these properties make the memebranes attractive candidates for possible application in the electrochemical devices. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation induced copolymerization. The copolymer composition was determined by elemental analysis of the dried gels, and was found to be close to that of the feed. The dependence of swelling properties and phase transitions on the IA comonomer content, temperature, pH values and presence of AgNPs were investigated. The hydrogels showed both thermo- and pH responses. By introducing small amounts of IA, swelling capacity increase, and the volume phase transition temperature (VPIT) of P(NiPAAm/IA) copolymers is transferred to higher values. Presence of AgNPs causes decrease of equilibrium swelling degree and VPIT, and allows of fine-tuning of these properties. Both the average values of compressive elastic modulus and Youngs modulus of elasticity were decreased by addition of IA as a consequence of looser structure of the network (increase in molar mass between two neighboring crosslinks and decrease in effective crosslinking density). The introduction of AgNPs promoted not only improvement of these mechanical parameters, but an improvement of stress at failure especially in the systems with the highest content of IA. In addition, Ag-P(NiPAAm/IA) hydrogel nanocomposites showed good antibacterial potentials. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - In this study, the potential of chitosan/poly(vinyl alcohol) (CS/PVA) blends as capping agent for stabilization of Ag-nanoparticles (Ag NPs) during their in situ gamma irradiation induced synthesis was investigated. The UV-vis absorption spectra show the surface plasmon absorption band around 410 nm, which confirms the formation of Ag-nanoparticles. It was found that the composition of CS/PVA blend affected the size of the obtained Ag-nanoparticles, as well as the parameters such as density, molar concentration and effective surface area, calculated from the experimentally obtained UV-vis absorption spectra and spectra obtained by simulation according to the Mie theory. SEM micrograph and XRD measurement indicated a spherical morphology and face centered cubic crystal structure of Ag-nanoparticles, with diameter around 12 nm. The values of optical band gap energy between valence and conduction bands (E-g), calculated from the UV-vis absorption spectra, also show dependence on the blend composition for Ag-CS/PVA colloids as well as for Ag-CS/PVA nanocomposites.

AB  - A nanosilver (nano-Ag)/poly(vinyl alcohol) (PVA) hydrogel device was synthesized with irradiation because it is a highly suitable tool for enhanced nano-Ag technologies and biocompatible controlled release formulations. The amount of the Ag+ ions released in vitro by the nano-Ag/PVA hydrogel device was in the antimicrobial parts per million concentration range. The modeling of the Ag+ ion release kinetics with the elements of the drug-delivery paradigm revealed the best fit solution (R-2 GT 0.99) for the Kopcha and Makoid-Banakars pharmacokinetic dissolution models. The term A/B, derived from the Kopcha model, indicated that the nano-Ag/PVA hydrogel was mainly an Ag+-ion diffusion-controlled device. Makoid-Banakars parameter and the short time approximated Ag+-ion diffusion constant reflected the importance of the size of the Ag nanoparticles. However, it appeared that the cell oxidation potential of the Ag nanoparticles depended on the diffusion characteristics of the fluid penetrating into the Ag/PVA nanosystem.

AB  - Magnetic field sensitive gels, ferrogels, are new promising class of hydrogels. The coupling of hydrogels and magnetic particles has potential application in soft actuators, such as artificial muscles, or for hyperthermia application. In this study, the composite of magnetite particles (Fe3O4) and poly(vinyl alcohol) (PVA) hydrogel is developed using gamma irradiation as a crosslinking agent. PVA and Fe3O4 were chosen due to their well-established biocompatibility, radiation crosslinking potential (PVA), mild magnetic properties and the Curie point near desired heating temperature range (Fe3O4). Physicochemical characteristics of these systems show the effect of the presence of particles in the process of radiation-induced crosslinking. Obtained PVA/Fe3O4 ferrogel composite has greater swelling capacity, activation energy of dehydration and dehydration rate compared to PVA hydrogel, crosslinked under the same conditions.

AB  - In order to obtain nanocrystalline material which can be used in MLCC production, the investigations of the influence of BaTiO3 powder tribophysical activation (TPA) on its structural changes, dielectric and ferroelectric properties have been performed. Microstructure development and crystal structure have been studied by mercury porosimetry method, SEM, EDS and X-ray powder diffraction analyses. The modifications of dielectric and ferroelectric properties of sintered samples have been examined and correlated with observed structural changes induced by TPA of starting powders. It has been found that dielectric and ferroelectric properties of tribophysically activated BaTiO3 could be tuned by controlling the grain size and lattice strain of activated nanostructured material.
