Аннотация: In this study, electrospinning was used to prepare ultrafine fibers from PHAs with different chemical compositions: P(3HB) and copolymers: P(3HB-co-4HB), P(3HB-co-3HV), and P(3HB-co-3HHx). The main process parameters that influence ultrafine fiber diameter and properties (polymer concentration, solution feeding rate, working distance, and applied voltage) have been investigated and their effects evaluated. The study revealed electrospinning parameters for the production of high-quality ultrafine fibers and determined which parameters should be varied to tailor the properties of the products. This study is the first to compare biological and physical-mechanical parameters of PHAs with different chemical compositions as dependent upon the fractions of monomers constituting the polymers and ultrafine fiber orientation. Mechanical strength of aligned ultrafine fibers prepared from different PHAs is higher than that of randomly oriented ones; no significant effect of ultrafine fiber orientation on surface properties has been found. None of the fibrous scaffolds produced by electrospinning from PHAs had any adverse effects on attachment, growth, and viability of NIH 3T3 mouse fibroblast cells, and all of them were found to be suitable for tissue engineering applications.

Аннотация: Magnetic Ni2+-zeolite/ferrosphere and Ni2+-silica/ferrosphere beads (Ni-ferrosphere beads - NFB) of a core-shell structure were synthesized starting from coal fly ash ferrospheres having diameters in the range of 0.063-0.050 mm. The strategy of NFB fabrication is an oriented chemical modification of the outer surface preserving the magnetic core of parent beads with the formation of micro-mesoporous coverings. Two routes of ferrosphere modification were realized, such as (i) hydrothermal treatment in an alkaline medium resulting in a NaP zeolite layer and (ii) synthesis of micro-mesoporous silica on the glass surface using conventional methods. Immobilization of Ni2+ ions in the siliceous porous shell of the magnetic beads was carried out via (i) the ion exchange of Na+ for Ni2+ in the zeolite layer or (ii) deposition of NiO clusters in the zeolite and silica pores. The final NFB were tested for affinity in magnetic separation of the histidine-tagged green fluorescent protein (GFP) directly from a cell lysate. Results pointed to the high affinity of the magnetic beads towards the protein in the presence of 10 mM EDTA. The sorption capacity of the ferrosphere-based Ni-beads with respect to GFP was in the range 1.5-5.7 mg cm-3. © The Royal Society of Chemistry.

    Biodegradable poly-3-hydroxybutyrate as a fertiliser carrier / T. G. Volova, S. V. Prudnikova, A. N. Boyandin // J. Sci. Food Agric. - 2016. - P4183-4193, DOI 10.1002/jsfa.7621 . - ISSN 0022-5142

biodegradable polymers -- controlled delivery systems -- fertilisers -- polyhydroxyakanoates
Аннотация: BACKGROUND: Increasing use of mineral fertilisers can lead to accumulation of fertilisers in soil, water and foodstuffs. One of the approaches to preventing these problems is to develop controlled release forms of fertilisers. RESULTS: Experimental formulations of the nitrogen fertiliser urea loaded in a degradable matrix of the natural polymer poly-3-hydroxybutyrate (P3HB) in the form of films, pellets and coated granules were constructed and investigated. Nitrogen release into soil occurred as the polymer was degraded, and it was dependent on the geometry of the carrier and the amount of nitrogen loaded in it, showing that nitrogen release can last for 30 days or longer and that release rates can be controlled by varying the fabrication technique employed. P3HB/urea formulations have a favourable effect on the soil microbial community. The use of embedded urea has a beneficial influence on the growth of creeping bentgrass (Agrostis stolonifera) and lettuce (Latuca sativa) and reduces removal of nitrogen with drain water. CONCLUSION: The slow-release nitrogen formulations developed in this study can be buried in soil together with seeds preventing nitrogen deficiency. The use of such slow-release formulations can decrease the amounts of chemicals in the environment and prevent their adverse effects on the biosphere. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry

Аннотация: Substrates pretreatment in suspensions of a detonation nanodiamond is widely used for nucleation of diamond growth by chemical vapor deposition (CVD). We found that iron inclusions in the nanodiamond provide catalytical growth of carbon nanotubes during CVD in a hot filament reactor (HF CVD). Carbon nanotubes grow in the area between two adjacent Si wafers. The diameters of such obtained nanotubes were in the range of 10-100 nm and the length of the tubes reaches about 10 mu m. The proposed HF CVD method has convincing potential for the fabrication of carbon nanotube coatings on a large surface area.

Аннотация: In the present study, we demonstrate the use of a disposable luciferase-based microfluidic bioassay chip for environmental monitoring and methods for fabrication. The designed microfluidic system includes a chamber with immobilized enzymes of bioluminescent bacteria Photobacterium leiognathi and Vibrio fischeri and their substrates, which dissolve after the introduction of the water sample and thus activate bioluminescent reactions. Limits of detection for copper (II) sulfate, 1,3-dihydroxybenzene and 1,4-benzoquinone for the proposed microfluidic biosensor measured 3 ?M, 15 mM, and 2 ?M respectively, and these values are higher or close to the level of conventional environmental biosensors based on lyophilized bacteria. Approaches for entrapment of enzymes on poly(methyl methacrylate) (PMMA) plates using a gelatin scaffold and solvent bonding of PMMA chip plates under room temperature were suggested. The proposed microfluidic system may be used with some available luminometers and future portable luminescence readers. © 2018 John Wiley & Sons, Ltd.

Аннотация: Industrial sea food residues, mainly crab and shrimp shells, are considered to be the most promising and abundant source of chitin. In-depth understanding of the biological properties of chitin and scientific advancements in the field of nanotechnology have enabled the development of high-performance chitin nanomaterials. Nanoscale chitin is of great economic value as an efficient functional and reinforcement material for a wide range of applications ranging from water purification to tissue engineering. The use of polymers and nanochitin to produce (bio) nanocomposites offers a good opportunity to prepare bioplastic materials with enhanced functional and structural properties. Most processes for nanochitin isolation rely on the use of chemical, physical or mechanical methods. Chitin-based nanocomposites are fabricated by various methods, involving electrospinning, freeze drying, etc. This review discusses the progress and new developments in the isolation and physico-chemical characterization of chitin; it also highlights the processing of nanochitin in various composite and functional materials.

Аннотация: A procedure has been developed to fabricate polymer tubes using solution casting inside template tubes. Polyester solution placed inside the vertically fixed template evaporated forming a hollow tube on the inner walls of the template. Silicone tubes used as the templates were permeable to solvent vapors and had relatively low adhesion to materials of the fabricated tubes, enabling their effortless removal. Parameters of the polymer tubes were determined by a type of the polymer, its concentration in the solution, and the inner diameter of the template. In the first method, a clamp was placed on the lower end of the template tube. A thickness of the new tube walls gradually increased from the open to the clamped end of the template tube. In another method viscous polymer solution without clamping was used; in this case, a polymeric bulkhead was formed in the middle of the tube. Two microbial polyesters, poly-3-hydroxybutyrate and poly-3-hydroxybutyrate-co-3-hydroxyvalerate, and also synthetic poly-L-lactide were used as model polymers. © 2020 Elsevier B.V.

Аннотация: Porous films have been prepared from degradable polymers-poly-3-hydroxybutyrate (PHB), poly-epsilon-caprolactone (PCL) and a blend of these polymers (1:3)-by adding porogen (camphor) to the polymer solution at 10%, 30% or 50% of the total mass of the polymer and porogen, and leaching it out afterwards. After the rinse, camphor content in films decreased to about 0.025%. The structure, physical/mechanical and biological properties of the films were investigated as dependent on their composition and porosity, which varied depending on the amount of camphor added. The surface of PHB films was porous, the PCL films were relatively smooth, and the PHB/PCL films had an intermediate structure. The addition of camphor increased the thickness (from 35 to 45 mu m, from 40 to 80 mu m and from 20 to 65 mu m for PHB, PCL and PHB/PCL, respectively) and porosity (from 4.2(+/- 3.6)% to 50.0(+/- 12.8)%, from 6.4(+/- 5.5)% to 54.5(+/- 6.0)% and from 4.9(+/- 4.8)% to 51.5(+/- 5.8)%, respectively) of the films. The introduction (and removal) of 10% camphor into the PHB and PHB/PCL films led to an approximately twofold increase in the polar component of the free surface energy (from 5.4 +/- 0.38 to 11.8 +/- 1.33 and from 2.7 +/- 0.13 to 5.2 +/- 0.09 mN/m, respectively) but in other cases, on the contrary, a decrease in this indicator was registered. The increase of camphor addition from 0% to 50% gradually impaired mechanical properties of the films: so, Young's modulus decreased from 3.6 to 1.8 GPa, from 0.30 to 0.12 GPa and from 0.50 to 0.20 GPa for PHB, PCL and PHB/PCL, respectively. At the same time, the water vapor transmission rate considerably increased from 197.37 +/- 23.62 to 934.03 +/- 114.34 g/m(2)/d for PHB films; from 1027.99 +/- 154.10 to 7014.62 +/- 280.81 g/m(2)/d for PCL films; and from 715.47 +/- 50.08 to 4239.09 +/- 275.54 g/m(2)/d for PHB/PCL films. Results of biocompatibility testing in the culture of NIH 3T3 mouse fibroblast cells showed that for the most of experimental samples cell adhesion and proliferation were comparable or superior to the corresponding parameters on the initial nonporous films. The best results were obtained for PHB films where at Day 3 of the experiment the registered cell density for experimental samples arrived at 2.66(+/- 0.26) x 10(5) cells/cm(2) versus 1.29(+/- 0.33) x 10(5) cells/cm(2) in the control. So, the proposed method can be used to construct highly porous cell scaffolds for cellular engineering.

Аннотация: The research on cellulose fiber-reinforced nanocomposites has increased by an unprecedented magnitude over the past few years due to its wide application range and low production cost. However, the incompatibility between cellulose and most thermoplastics has raised significant challenges in composite fabrication. This paper addresses the behavior of plasma-modified polyethylene (PE) reinforced with cellulose nanofibers extracted from isora plants (i.e., isora nanofibrils (INFs)). The crystallization kinetics of PE–INF composites were explained using the Avrami model. The effect of cellulose nanofillers on tuning the physiochemical properties of the nanocomposite was also explored in this work. The increase in mechanical properties was due to the uniform dispersion of fillers in the PE. The investigation on viscoelastic properties confirmed good filler–matrix interactions, facilitating the stress transfer. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

Аннотация: The research on cellulose fiber-reinforced nanocomposites has increased by an unprecedented magnitude over the past few years due to its wide application range and low production cost. However, the incompatibility between cellulose and most thermoplastics has raised significant challenges in composite fabrication. This paper addresses the behavior of plasma-modified polyethylene (PE) reinforced with cellulose nanofibers extracted from isora plants (i.e., isora nanofibrils (INFs)). The crystallization kinetics of PE-INF composites were explained using the Avrami model. The effect of cellulose nanofillers on tuning the physiochemical properties of the nanocomposite was also explored in this work. The increase in mechanical properties was due to the uniform dispersion of fillers in the PE. The investigation on viscoelastic properties confirmed good filler-matrix interactions, facilitating the stress transfer.

Аннотация: Single-crystal diamonds in the form of micrometer-scale pyramids were produced using a combination of hot-filament (HF) chemical vapor deposition (CVD) and thermal oxidation processes. The diamond pyramids were compared here with similar ones that were manufactured using plasma-enhanced (PE) CVD. The similarities revealed in the morphology, Raman, and photoluminescent characteristics of the needles obtained using the hot-filament and plasma-enhanced CVD are discussed in connection with the diamond film growth mechanism. This work demonstrated that the HF CVD method has convincing potential for the fabrication of single-crystal diamond needles in the form of regularly shaped pyramids on a large surface area, even on non-conducting substrates. The experimental results demonstrated the ability for the mass production of the single-crystal needle-like diamonds, which is important for their practical application.
