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  - One of today's imperatives is the effective removal of pollutants from the biosphere, particularly from natural and wastewater sources. The removal of metal ions from solutions has long been a goal of numerous investigations, and hydrogels have been utilized as sorbent materials for this purpose. [1,2] This research was performed in order to create a new class of poly(oligo(propylene glycol methacrylate)/oligo(ethylene glycol methacrylate))/acid), abbreviated as p(OPGMA/OEGMA/acid), temperature-responsive copolymeric hydrogels and to analyze the influence of different acids on the volume phase transition temperature (VPTT) of the obtained hydrogels and on the efficiency of Mn+2 removal from the water. In this work, three acids were used: itaconic (IA), acrylic (AA), and methacrylate (MA), which were incorporated into the composition of the hydrogel in the monomer feed ratio OPGMA/OEGMA/acid of 95:2:3. Henceforth, the obtained hydrogels p(OPGMA/OEGMA/acid) were synthesized for the first time by γ-irradiation polymerization and crosslinking of monomers from a water/ethanol solution. The hydrogels were put through swelling analysis and testing as potential sorbents once the high level of gel content was confirmed. Taking into account the size of the metal ions, their concentration in the solution, and the porosity of the gel, the results show that hydrogels can be employed to remove manganese ions from solutions.

AB  - Polyolefins (POs) are currently the most widely used engineering plastics due to their
relatively low cost, durability, and ease of processing. A feature such as inertness makes
polyolefins suitable for applications such as food packaging and medical devices. For
the purpose of this study, polyethylene (PE) with good rigidity, hardness, impact
strength, environmental stress cracking resistance, and excellent processability, and
polypropylene (PP), with high fluidity and very good transparency, were selected
polyolefins [1,2]. Knowing that most of the polymer applications are strongly dependent
on the initial state of the products, i.e., their morphology, thermal properties, and
crystallinity, it is possible to obtain a great variety of morphologies and supermolecular
formations by varying different conditions in the preparation process, e.g. cooling
conditions during the crystallization process from the melt.
One of the aims of this work was to compare the results obtained for two different
methods of sample preparation, quenching, and slow cooling. Initial preparation was
performed for selected POs by rapid quenching in ice water and slow air cooling after
compression molding. Further, the prepared samples were characterized by SEM,
WAXD, FTIR, and mechanical measurements.
The obtained results indicated that PP is much more sensitive to the method of sample
preparation than PE, as well as that the initial preparation of samples plays a decisive
role in the final properties of materials for polymeric medical devices.

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 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  - 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.

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  - In this work, we present the results obtained by femtosecond laser processing of AISI D2 steel and the widely applicable titanium-based alloy, Ti6Al4V. Patterning the materials surfaces was done by a Ti: sapphire system at 775 nm wavelength and 200 fs pulse duration, while varying the output pulse energies and the scanning speed. The formation of laser-induced periodical surface structures were found for both materials.

AB  - The aim of this study is to evaluate the size and stability of radiolytically produced silver clusters. The clusters obtained by the gamma irradiation of a mixture of a silver salt and polyvinyl alcohol (PVA) were studied both theoretically and by mass spectrometry. MALDI TOF mass spectrometry of the Ag-n clusters showed the presence of clusters containing between 5 and 29 atoms. Both the theoretical and experimental results of this paper show that the most stable clusters are small clusters with an odd number of atoms. The stability of these clusters is correlated with the clusters electronic configuration. (C) 2012 Elsevier Ltd. All rights reserved.

AB  - A primer is a strand of nucleic acid that serves as a starting point for DNA
synthesis. DNA, as a large molecule, is very difficult for analysis by means of mass
spectrometry. However, primer, as a short sequence of nucleic acid, is much more
convinient for e.g. MALDI TOF MS analysis. Mass spectrometric experiment
resulted in quality MALDI TOF spectra of 3 primers. Compound 3-HPA (3-
hydroxypicolinic acid) showed the best results as matrix. AFM studies were also
conducted, for both pure primer samples and hybrids of primer molecule with
single wall carbon nanotubes (SWNT). Thus, obtained functionalisation of SWNT
with DNA primers was confirmed by AFM imaging. AFM images clearly showed
wrapping of DNA structures around nanotube „template“. Functionalisation of
SWNT is very important for potential applications of nanotubes in biomedical
field. MALDI TOF mass spectrometry, in combination with AFM imaging, proved
its great potential in analysis of short DNA sequences, and indicated the possibility
of investigating more complex DNA structures.

AB  - Collagens, one of the most abundant on the Earth, are family of proteins which constitute the basis of connective tissue (extracellular matrix) in multicellular organisms. We used collagen type II from bovine Achilles tendon. In further work, collagen has been studied by transmission electron microscopy (TEM) and atomic force microscopy (AFM). Using TEM we successfully obtained images of collagen and whole collagen fibrils. Using AFM we captured images of whole collagen as well as images of fragments from collagenase-treated collagen (it was digested with collagenase from Clostridium histolycium). AFM images of collagenase-treated collagen showed many fibrils grouping into large bundles – collagen fiber. Based on obtained images we studied surface morphology, shape and length of fragments from collagenase-treated collagen.

AB  - Collagen is the most frequently occuring fibrillar protein in mammals, which can be found in cartilage, tendon, bone, ligament, skin, etc. The structure of collagen is based on a complicated helix structure of single chains of amino acids (most abundant is glicine-Gly, proline-Pro and hydroxyproline-Hyp) which are connected by hydrogen bonds. We tried to establish MALDI method to get better resolution of collagen’s mass spectra. Digested collagen (type II from bovine Achilles tendon which was digested with collagenase from Clostridium histolycium) has been analysed on MALDI-TOF MS in order to find peptide’s fragments that are characteristic for collagen. In mass spetra we found peaks of peptides, which is highly indicative for collagen (GlyPro-Hyp, Gly-Pro-Asp, Gly-Pro-Glu ect.) We hope that it should be possible to obtain MS analysis and structure characterization of collagen by MALDI-TOF/TOF in future.

AB  - Bone is composed of two phases. The organic phase is made of collagen fibrils assembled in broad fibers acting as a template for mineralization. The mineral phase comprises hydroxyapatite (HAP) crystals grown between and inside the collagen fibers. We have developed a material using functionalized carbon nanotubes, carbon fibers and glasy carbon as scaffold to initiate in vitro mineralization. Mentioned carbon materials are functionalized with carboxylic groups prior to decorating. All samples were dispersed in ultra-pure water and incubated for 2 weeks in a synthetic body fluid with dispersed HAP, in order to induce the calcification of the functionalized carbon materials. Atomic force microscopy (AFM) and transmision electron microscopy (TEM) showed that Ca2+ and PO4 3- ions were deposited as round-shaped nodules. Raman spectroscopic studies confirmed the HAP formation, and image analysis made on TEM pictures showed that HAP were packed around and inside the carbon materials together. All three types of investigated carbon materials leading to successful calcification of collagen. This suggests that it takes the presence of carbon materials to prevent it from calcification of collagen, independent of the structures of the material.
