Correct elucidation of physiological and pathological processes mediated by extracellular vesicles (EV) is highly dependent on the reliability method used for their purification. Currently available chemical/physical protocols sample fractionation are time-consuming, often scarcely reproducible yields low. Immuno-capture based approaches could represent an effective purification alternative to obtain homogeneous EV samples. An easy-to-operate chromatography system was set-up intact EVs a...
Magnetization of a compact alloy sample, prepared by sintering mixture powders 50.0 wt% Fe, 47.0 BaTiO3 and 3.0 TiO2 composed BaFe12O19 nanocrystals amorphous nanoparticles embedded in an matrix, raises with increasing the strength external magnetic field. When heating to up 65°C magnetization does not change, however further from 65 350°C results its slow decline. A rapid drop temperature range 350 500°C is caused transformation directed paramagnetic, ferromagnetic weakly domains into...
Large-scale application of alginate-poly-L-lysine (alginate-PLL) capsules used for microencapsulation living cells is hampered by varying degrees success, caused tissue responses against the in host. A major cause proinflammatory PLL which applied at surface to provide semipermeable properties and immunoprotection. In this study, we investigated whether poly(ethylene glycol)-block-poly(L-lysine hydrochloride) diblock copolymers (PEG-b-PLL) can reduce on alginate-matrices. The PEG-b-PLL was...
Abstract Alginate‐based microcapsules are being proposed for treatment of many types diseases. A major obstacle however in the successes is that these capsules having large lab‐to‐lab variations. To make process more reproducible, we propose to cover surface alginate with diblock polymers can form polymer brushes. In present study, describe stepwise considerations successful application copolymer polyethylene glycol (PEG) and poly‐ L ‐lysine (PLL) on beads. Special procedures had be designed...
Kinetic and operational electrolysis parameters determine the polarization characteristics, electrodeposition current efficiency, morphology, chemical composition microstructure of nickel/iron/tungsten alloy deposits. The alloys electrodeposited at a density 50 mAcm-2 to 1000 contain an amorphous phase nanocrystals FCC solid solution iron tungsten in nickel. During annealing temperatures above 500?C, crystallization, crystalline grain growth reduction both internal microstrain minimum...
Strategies based on the enzyme application are increasingly replacing conventionalchemical procedures because of their efficiency, quicker performance and environmentalprotection. However, natural enzymes can rarely be used in industrysince beneficial features cannot endure industrial conditions. Additionaldrawbacks inhibition by reaction products difficultyto removed from mixture. The most promising techniqueto substantially improve properties, such as activity, pH, thermal...
Nowadays, unsaturated polyester resins (UPR) are mainly obtained from non-renewable resources. The ever-increasing regulations and the continuous demand for more sustainability have led to extensive research towards environmentally suitable alternatives petroleum-based materials. However, one of main disadvantages bio-based UPR is their relatively high viscosity compared petrochemical ones. In order overcome this drawback, in work, we investigated possibility lower resin utilizing a mixture...
Nanostructured nickel-iron-tungsten alloy coatings were electrodeposited from an ammonia citrate bath on steel and copper substrates at current densities in the range of 50 to 300 mA cm−2. The contents iron tungsten increase that nickel decreases with increasing deposition density. At below 100 cm−2, smooth shiny no cracks craters are deposited. Higher result matte developing craters. XRD analysis showed contain nanocrystals FCC structured solid solution embedded amorphous matrix. Increasing...
The synthesis of poly(N-isopropylacrylamide)-b-poly(L-lysine) and poly(N- isopropylacrylamide-co-acrylamide)-b-poly(L-lysine) copolymers was accomplished by combining atom transfer radical polymerization (ATRP) ring opening (ROP). For this purpose, a di-functional initiator with protected amino group successfully synthetized. ATRP N-isopropylacrylamide yielded narrowly dispersed polymers consistent high yields (~80%). Lower (~50%) were observed when random acrylamide where synthesized....
