AB  - Hydrogels with oligo(ethylene glycol) (OEG), oligo(propylene glycol) (OPG), and for the first time with combined OEG/OPG pendant chains within the methacrylate (MA) network, were synthesized and the swelling behavior, thermal properties, microstructure, and genotoxicity were investigated. Prior to hydrogel fabrication, an optimized method was developed for oligo(propylene glycol) methacrylate (OPGMA), i.e., oligomer with an LCST below a temperature at which synthesis occurs, indicating that proper preparation and tuning of reaction conditions were required. PEG6MA and PPG5MA homopolymers, as well as P(EG6/PG5)MA copolymer hydrogel, were produced by gamma radiation-induced polymerization and crosslinking of OEG and OPG monomers from the monomer-solvent mixture by using different water/ethanol composition as a solvent and by exposing the reaction mixture to various radiation doses. The combination of OEG and OPG pendant chains within the same network was advantageous in that it allowed an easy tuning of the phase transition temperature. Thus, the volume phase transition (VPT) at temperatures above 70 °C observed in the case of PEG6MA, and in the case of PPG5MA at temperatures below 15 °C, could easily be tuned close to physiological temperatures for P(EG6/PG5)MA hydrogel. Finally, all obtained thermoresponsive hydrogels showed non-genotoxic and non-cytotoxic properties, which indicate promising potential for biomedical applications.

AB  - Magnesium (Mg) is an essential element in the human body primarily stored in bones. Mg ions have many potential benefits for bone tissue showing excellent osteogenic inductivity [1]. The aim of this study was to synthesize Mg substituted hydroxyapatite (Mg-HAP) for application in bone tissue engineering and to assess its behaviour in conditions mimicking physiological ones. Mg-HAP was synthesized using reflux method and its structural and morphological characterization was performed by XRD, FTIR and SEM. The changes in local structure and composition after irradiation and immersion in physiological solution and simulated fluid were assessed by electron paramagnetic resonance (EPR) spectroscopy. The results of EPR analysis pointed out that irradiation did not change the composition and structure of Mg-HAP. After immersion in model media (simulated body fluid and saline solution), the small amount of by-product of synthesis disappeared after 24 h and Mg-HAP remained the only phase. Also, the radical signals in EPR spectra faded away after 28 days in model media, showing that the structure and composition of Mg-HAP both went through a kind of stabilization in simulated physiological conditions. These results make the investigated Mg-HAP promising material for application in bone tissue engineering.

AB  - In this study, zinc phthalocyanine was evaluated as a possible chemical dosimeter for gamma rays at low-medium dose ranges in solution form and PVA film. The zinc phthalocyanine was successfully synthesized with a high yield under microwave irradiation at 200 °C. The calibration curves of absorbance versus dose of gamma irradiation show excellent linearity over a wider dose range (1 - 25kGy). After being irradiated, the samples' color changed from blue to yellow.

AB  - For many years now, thermally actuated hydrogels have been the ones most studied and employed in the field of polymeric biomaterials. The monomers, N-isopropyl acrylamide (NiPAM), and oligo(propylene glycol) methacrylate (OPGMA) were selected based on the sharp temperature response of their corresponding hydrogels in a known range of temperatures.1,2 This research was performed in order to create a new class of P(NiPAM/OPGMA) temperature-responsive hydrogels, and to analyze the influence of different content of monomers on the volume phase transition temperature (VPTT) of the obtained hydrogels. One of the objectives of this study was to provide insight into the effects of applied radiation dose on the swelling and mechanical properties of the hydrogels.  In further work, P(NiPAM/OPGMA) hydrogels were synthesized for the first time by γradiation crosslinking of monomers from water/ethanol solution. After the high sol-gel conversion was established, xerogels were subjected to swelling analysis and tested for the mechanism of water diffusion within the hydrogels. The obtained results indicated that new hydrogels based on NiPAM and OPGMA show promising potential for water treatment application due to the relatively high swelling degree of hydrogels and the ability to combine their VPTT close to annual river water temperatures in Serbia.

AB  - The synthesis represents a crucial step for achieving the unique properties of nanomaterials. Gamma (γ) - radiation-induced synthesis possesses several advantages over other conventional synthetic routes such as production of clean materials, the possibility of simultaneous synthesis and sterilization, in-situ generation of radiolysis products and the lack of necessity for initiators and crosslinking reagents in the case of polymer-based materials fabrication. γ-radiation induced synthesis has been utilized in the development and modification of various types of systems, including metal, metal oxide and alloyed nanoparticles, carbon-based nanomaterials, polymer based nanomaterials and nanocomposites etc. In this lecture, fundamentals of radiation chemistry will be given with an emphasis on the synthesis of nanomaterials in aqueous solutions. The effects of the total dose, dose rate, and the addition of different solutes to tailoring the synthesized materials’ composition, form, shape, size and size distribution will be demonstrated. The possible applications of so obtained materials in industry and biomedicine will be presented.

AB  - As magnesium is an important trace element in bone and teeth, and plays a key role in bone metabolism, the aim of this study was to obtain magnesium substituted hydroxyapatite (MgHAP) and to assess its application potential. Upon synthesis, the changes in local structure and composition after irradiation and immersion in physiological solution and simulated fluid were followed by electron paramagnetic resonance (EPR) spectroscopy. Samples were also characterized by XRD, FTIR, SEM, EDS, AAS and TGA. The results showed that irradiation did not affect the composition and structure of Mg-HAP. After immersion in model media, the small amount of by-product of synthesis disappeared already after 24 h and Mg-HAP remained as the only phase. Also, the radical signals in EPR spectra faded or completely disappeared after 28 days in model media, which could indicate that the structure and composition of Mg-HAP both went through a kind of stabilization in conditions mimicking physiological ones. All these indicate that investigated Mg-HAP has good potential for biomedical application considering its behaviour in model media which imitate physiological conditions.

AB  - Due to its similarity with biological apatite found in vertebrate hard tissues, calcium hydroxyapatite is one of the most investigated materials in bone tissue engineering. As the biological apatite is not stoichiometric, ion substituted hydroxyapatites attract much atention since they more closely mimic the composition of natural bone. Although there are many investigations of the influence of foreign ions on the structure and physico-chemical properties of ion-substituted hydroxyapatites, there is scarse information on their behaviour in different media. In the present study, magnesium (Mg), that plays a key role in bone metabolism and silicon (Si), that is necessary for normal skeletal development, were used as ion substitutes. The behaviour of Mg and Si substituted hydroxyapatite in simulated body fluid was investigated by XRD, FTIR and SEM. Obtained results confirmed great potential of these substituted hydroxyapatites for biomedical applications.

AB  - Oligo (ethylene glycol) oligo (propylene glycol) methacrylates (OEGOPGMA) with diferent numbers of ethylene glycol (EG) and propylene glycol (PG) units in backbone were used for the preparation of new thermoresponsive POEGOPGMA hydrogels; EG6PG3MA and EG3PG6MA monomers were used; and three diferent POEGOPGMA hydrogels (PEG6PG3MA, PEG3PG6MA and P(EG6PG3/EG3PG6) MA copolymer with equal mol% of previous two) were fabricated from mono‑ mer–solvent (OEGOPGMA–water/ethanol) mixture by gamma radiation. Charac‑ terisation of the hydrogels was conducted by swelling, UV–Vis, scanning electron microscope, diferential scanning calorimetry and in  vitro biocompatibility (cyto‑ compatibility and haemolytic activity) investigations. The modelling of drug release and difusion characteristics was tested using cephalexin drug. For the frst time, it was shown how to efectively tune the volume phase transition temperature (VPTT) values of the hydrogels by changing the ratio of more hydrophilic (EG) and more hydrophobic (PG) units in (EGPG) “block” pendant chains. The obtained hydrogels revealed the great potential for diferent biomedical applications not only due to the possibility to tune VPTT in the desired way but also due to the good biocompatibil‑ ity and controlled drug delivery within the target temperature range.

AB  - The oligo(ethylene glycol) dimethacrylate (OEGDMA), one of the most commonly utilized crosslinking monomers, was used to tailor thermoresponsive POEGDMA hydrogels by varying the monomer/solvent feed ratio (from 10 to 100 wt% of monomer). For the first time, synthesis of different POEGDMA homopolymeric networks was performed by gamma radiation, and due to the expected thermoresponsiveness their temperature-dependent properties were extensively analysed. The sol-gel study was performed as the first step after radiation-induced synthesis. The swelling properties were investigated over the wide pH (2.2–9.0) and temperature (5–80 °C) range. Characterization of structure and properties was additionally conducted by SEM, DSC, FTIR, and UV–Vis spectroscopy. The results indicated that all POEGDMA hydrogels showed a high gel content, inverse thermoresponse and volume phase transition temperature (VPTT) with no respect to initial preparation. On the other hand, by altering the monomer/solvent ratio in the prepolymerisation mixture a large diversity in the microstructure, swelling capacity and VPTT was obtained. © 2019 Elsevier Ltd

AB  - New hydrogels based on different oligo(alkylene glycol) methacrylate (OAGMA) with inverse thermoresponse and volume phase transition temperature (VPTT) were obtained and characterised in this paper. Synthesis was performed from monomer-solvent (OAGMA-water/ethanol) mixture by simultaneous radiation-induced polymerisation and crosslinking; three different OAGMA (EG(6)MA, EG(6)PG(3)MA, and PG(5)MA) were used. The main focus was made on PEG(6)PG(3)MA hydrogel based on ethylene glycol (EG) propylene glycol (PG) pendant chains with EG (6) and PG (3) block units, since in the case of POPGMA and POEGMA homopolymers (i.e. hydrogels with pure PG and EG pendant chains) the VPTTs were observed far below and far above the human body temperature, respectively. Characterisation of the hydrogels was performed by swelling, UV-Vis, FTIR, SEM, DSC and in vitro biocompatibility (cytocompatibility and haemolytic activity) investigations. Due to the possibility to combine VPTT close to human body temperature with good biocompatibility, new hydrogel based on EGPG block pendant chains showed promising potential for different biomedical applications.

AB  - New hydrogels based on different oligo(alkylene glycol) methacrylate (OAGMA) with inverse thermo-response and volume phase transition temperature (VPTT) close to human body temperature were investigated in this work. Synthesis was performed from monomer-solvent mixture by gamma radiation; four different OAGMA (EG6MA, EG6PG3MA, EG3PG6MA and PG5MA) were used. The main focus was made on hydrogels based on EGxPGy pendant chains with different number of ethylene glycol and propylene glycol units in “block” backbone since in the case of POPGMA and POEGMA homopolimers (e.g. hydrogels with pure PG and EG pedant chains) the VPTTs were observed far below and far above the human body temperature, respectively. Characterisation of the hydrogels was performed by swelling, UV-Vis, FTIR, SEM, DSC and in vitro biocompatibility investigations. Due to the possibility to combined VPTT close to human body temperature with good biocompatibility, new hydrogels based on EGPG “block” pedant chains show great potential for biomedical applications.

Synthesis was performed from monomer-solvent mixture by gamma radiation; four different OAGMA (EG6MA, EG6PG3MA, EG3PG6MA and PG5MA) were used. The main focus was made on hydrogels based on EGxPGy pendant chains with different number of ethylene glycol and propylene glycol units in “block” backbone since in the case of POPGMA and POEGMA homopolimers (e.g. hydrogels with pure PG and EG pedant chains) the VPTTs were observed far below and far above the human body temperature, respectively. Characterisation of the hydrogels was performed by swelling, UV-Vis, FTIR, SEM, DSC and in vitro biocompatibility investigations. Due to the possibility to combined VPTT close to human body temperature with good biocompatibility, new hydrogels based on EGPG “block” pedant chains show great potential for biomedical applications.",

AB  - The purpose of this study was to attain oligo(propylene glycol) methacrylate (OPGMA) based hydrogels for different biomedical applications. Since the volume phase transition temperature (VPTT) of poly(oligo(propylene glycol) methacrylate) (POPGMA) homopolymer was below room temperature, it was necessary to tune the thermoresponsiveness and the VPTT to higher temperatures; radical copolymerisation of OPGMA with more hydrophilic and/or pH responsive monomers was used to adjust these values. A series of copolymeric hydrogels with different ratios of OPGMA, 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) was synthesised by gamma radiation. The swelling properties were preliminarily investigated over a wide pH (2.2-9.0) and temperature (4-80 degrees C) ranges. Additional characterization of their structure and properties was conducted by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The presented results revealed temperature/pH dual responsive P(OPGMA/IA) and P(OPGMA/HEMA/IA) copolymers with large diversity in swelling properties, as a result of the addition of OPGMA thermoresponsive units with a lower critical solution temperature (LCST) and IA pH responsive units. It was demonstrated that VPTT can be significantly shifted to higher (e. g. body) temperatures at higher pH values (pH = 4) by increasing the IA content in the hydrogel composition. Due to the possibility of making dual responsive copolymers in the manner explained in this paper, OPGMA based hydrogels show potential for different biomedical applications.

AB  - The synthesis of poly(oligo(propylene glycol) methacrylate) (POPGMA) from functionalised oligo(propylene glycol) methacrylate (OPGMA) monomers by gamma radiation-induced radical polymerisation is reported for the first time; POPGMA homopolymeric hydrogel with oligo(propylene glycol) (OPG) pendant chains, as a non-linear PPGMA-analogue, was synthesised from an monomer-solvent (OPGMA(375)-water/ethanol) mixture at different irradiation doses (5, 10, 25, and 40 kGy). Determination of the gel fraction was conducted after synthesis. The swelling properties of the POPGMA hydrogel were preliminarily investigated over wide pH (2.2-9.0) and temperature (4-70 degrees C) ranges. Additional characterisation of structure and properties was conducted by UV-vis and Fourier transform infrared (FTIR) spectroscopy as well as by differential scanning calorimetry (DSC). In order to evaluate the potential for biomedical applications, biocompatibility (cytocompatibility and haemolytic activity) studies were performed as well. Sol-gel conversion was relatively high for all irradiation doses, indicating radiation-induced synthesis as a good method for fabricating this hydrogel. Thermoresponsiveness and variations in swelling capacity as a result of thermosensitive OPG pendant chains with a lower critical solution temperature (LCST) were mainly observed below room temperature; thus, the volume phase transition temperature (VPTT) of POPGMA homopolymeric hydrogel is about 15 degrees C. Furthermore, POPGMA has satisfactory biocompatibility. The results indicate that the hydrogels with propylene glycol pendant chains can be easily prepared by gamma radiation and have potential for different applications as smart and biocompatible polymers.

AB  - Changes in the structure and dielectric properties of low-density polyethylene were created by gamma irradiation in air, deionised water and nitrogen. Role of irradiation media on dielectric and charge trapping behaviour was studied through dielectric loss and thermally stimulated discharge current measurements. Changes in magnitude, position and activation energy of all dielectric relaxations (gamma, beta and alpha) were found to be dependent on crosslinking and oxidative degradation, two competitive processes which can be tuned by radiation dose and media. Largest changes in the position and activation energy were found for the beta relaxation due to its cooperative nature.

AB  - The molecular relaxation behaviour of polyolefins exposed to high-energy radiation has been investigated by dielectric loss (tan delta) analysis. Therefore, low-density polyethylene, high-density polyethylene (HDPE), and isotactic polypropylene (iPP) were gamma-irradiated in air to various absorbed doses (up to 700 kGy). All relaxation zones (alpha, beta, gamma, and delta in the order of decreasing temperature), between 25 K and melting temperature, were studied. The radiation-induced changes observed in the dielectric relaxation spectra were related to the modifications in the structural and morphological parameters attributed to exposure of the polyolefins to radiation. Wide-angle X-ray diffraction, infrared spectroscopy, and gel measurements were used to determine the radiation-induced changes in the crystalline structure, oxidative degradation, and the degree of network formation, respectively. The present study reveals high dielectric and/or relaxation sensitivity of polyolefins to gamma radiation. Disappearance of some relaxations (such as beta relaxation in HDPE and low temperature gamma and delta relaxations in iPP) is clearly observed with irradiation. For the other relaxations, besides the large changes in the relaxation intensity, radiation also induces smaller/larger changes in the distribution of relaxation times, peak position, and activation energy.

AB  - The molecular relaxation behavior of an ice-quenched high density polyethylene (HDPE) subjected to solid-state stretching at elevated temperature (100 degrees C) to various draw ratios (up to lambda=13.7) was examined by means of dielectric spectroscopy. All relaxation zones (alpha, beta and gamma, in order of decreasing temperature) between 25 K and melting temperature were studied in the frequency range from 1 kHz to 1 MHz. The changes observed in different dielectric relaxations were related to the orientation-induced modifications of the structural and morphological parameters. In order to investigate orientation-induced structural changes, optical microscopy (OM), scanning electron microscopy (SEM), wide angle X-ray scattering (WAXS), and differential scanning calorimetry (DSC) were employed. Hermans orientation function (f(c)) was used to quantify the degree of crystal orientation. Complete disappearance of the already weak beta relaxation with orientation is attributed to the increase in crystallinity, but the contribution due to a more restricted chain segment mobility in the interlamellar regions of oriented specimens should also be taken into account. Presented results also reveal two different orientation-induced dynamics in the evolution of the dielectric alpha and gamma relaxations connected with the main transformation stages in the drawing of crystalline polymers. The transformation of the initial isotropic into a fully oriented fibrillar structure introduces large changes in the dielectric relaxation spectra of HDPE, especially in the alpha relaxation zone; by contrast, with further increase in the draw ratio much smaller changes are observed due to the deformation of the fiber structure by longitudinal sliding motions of microfibrils and/or by fibrils slipping past each other.

AB  - A series of copolymeric hydrogels with different mole ratios of 2-hydroxyethyl methacrylate (HEMA), itaconic acid (IA) and oligo(ethylene glycol) acrylate (OEGA) was synthesised by gamma radiation. In our previous paper, the swelling properties of P(HEMA/IA/OEGA) terpolymeric hydrogels were preliminary investigated, showing dual (pH and thermo) responsiveness and large variation in the swelling capacity. In this study, the basic structural parameters of the P(HEMA/IA/OEGA) networks such as the average molecular weight between cross-links ((M) over bar (c),), effective cross-linking density (nu(e)), polymer-solvent interaction parameter (chi) and mesh size (xi) were determined by using swelling and mechanical measurements. Cytocompatibility and hemolytic activity measurements were used to investigate the influence of hydrogel composition (i.e. the influence of different fractions of IA and OEGA) on the biocompatibility of the hydrogels obtained. The microbe penetration test against Staphylococcus aureus and Escherichia coli was performed, too. It was observed that variation in hydrogel composition strongly influenced the smart swelling behaviour and introduced some changes in biocompatibility. The results indicate that P(HEMA/IA/OEGA) terpolymers, as smart and biocompatible hydrogels, have wide diversity and great potential for different biomedical applications, but their optimisation study can give the best candidate for certain biomedical applications.

AB  - Silver nanoparticles were fabricated via in situ reduction of silver nitrate embedded in swollen P(HEMA/IA) hydrogel, using gamma radiolysis method. Copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA), previously synthesised by gamma radiation for wound dressing application, were used as a carrier and a stabilising agent, while ethyl alcohol was used as a free radical scavenger. The influence of different P(HEMA/IA) hydrogels and silver salt concentrations on the size and distribution of nanoparticles was investigated. The Ag/P(HEMA/IA) nanocomposites were characterised by high resolution scanning electron microscopy, energy dispersive spectroscopy, wide-angle X-ray diffraction, UV-Vis spectroscopy and swelling measurements. Escherichia coli (Gram-negative bacterium), Staphylococcus aureus (Gram-positive bacterium) and Candida albicans (fungus) were used to prove the antimicrobial properties of Ag/P(HEMA/IA) nanocomposites. The inhibition kinetics of bacteria growth was investigated by measuring the colony-forming unit. The antimicrobial effectiveness of the Ag/P(HEMA/IA) hydrogel nanocomposite was demonstrated even at small silver concentrations. P(HEMA/IA) hydrogels containing nanosilver particles was found suitable to be used as wound dressing.

AB  - Different polyolefines (low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE) and isotactic polypropylene (iPP)) were oriented via solid-state stretching at an elevated temperature. In order to investigate orientation-induced changes in microstructure and crystallinity, optical microscopy (OM), scanning electron microscopy (SEM), wide angle X-ray scattering (WAXS) and differential scanning calorimetry (DSC) were employed. To quantify the degree of molecular orientation WAXS data were used to calculate Hermans orientation function (f(c)); the results reinforce the morphological picture obtained from OM and SEM confirming Peterlins molecular model of drawing. Furthermore, orientation-induced changes in the crystalline phase, especially in its volume and perfection, were observed by DSC and WAXS. Comparison between these data showed that the biggest change in the degree of crystallinity was achieved during the transformation of the initial lamellar into fibrillar structure. After completion of this transformation further orientation, which occurs through plastic deformation of fibre structure, introduces only minor changes in crystallinity. The overall orientation-induced behaviour hasnt been considerably influenced by the structural differences amongst polyolefins.
