Аннотация: The properties of field electron emission for diamond/pyrocarbon nanocomposites produced from diamond particles surrounded by a pyrocarbon matrix were studied. Low-threshold emissions at fields of ?1 V/?m with no activation or hysterisis in the current versus voltage (I/V) behaviour were observed for the materials. Scanning tunneling-field emission microscopy was used to study the mechanisms of low-field electron emission from the composites, and a model based on quantum well effect at the diamond/graphite interface was proposed and discussed.

Аннотация: The thermal conductivity, k, of diamond/carbon composites with different ratios of sp 2/sp 3-bonded carbon is measured by the laser flash technique. The thermal conductivity of nanocomposites containing 6 nm diamond particles falls within the range of k=0.003-0.017 W/cmK at room temperature. The thermal conductivity increases while nanopores are gradually filled with pyrolytic carbon (pyrocarbon/diamond mass ratio variation of 0.0-0.5). Transmission electron microscopy data reveal a fairly uniform mixture of two carbon phases, the diamond and matrix having similar grain sizes. Estimates show that the phonon free path is limited by dimensions of carbon matrix layer. Thermal data for coarse-grain (1-2 ?m) composites are also given for comparison.

Аннотация: The physical properties of bulk composite materials consisting of nanodiamond, pyrolytic carbon, and nanopores were investigated. Samples were irradiated in a channel of the reactor by fast neutrons (E 0.5MeV) in ampoules with helium and in an aqueous medium. The dependences of the electrical transport properties of materials with different compositions on the dose of irradiation with fast neutrons were studied. A nonmonotonic change in the electrical resistivity with an increase in the neutron fluence was revealed. Possible explanations were offered for the observed dependence of the electrical resistivity on the neutron fluence, in particular, those related to the physical processes occurring in surface states of the three-phase system of the nanocomposite.

Аннотация: Properties of the field electron emission for diamond/pyrocarbon nanocomposites produced from diamond particles surrounded by an sp(2)-bonded pyrocarbon matrix are considered as functions of a size of diamond particles selected in the range of 5 nm - 5 mum, and of an average thickness of the pyrocarbon shell controlled by the pyrocarbon/diamond mass ratio varied from 0 to 0.5. The low-threshold emission at fields of greater than or equal to1 V/mum with ''no activation/no hysteresis'' I-V behavior was observed for these materials using tungsten tip microprobes as well as a fluorescent screen. A specially designed scanning tunneling-field emission microscope was used for simultaneous mapping of field emission intensity, topography, work function, and electrical resistivity to study the mechanisms of the emission from the composites and well-emitting chemical vapor deposition diamond films. It was found that for both of the materials emission centers are associated with interfaces between diamond and sp2-bonded carbon phases. Possible mechanisms of the low-field electron emission for the diamond/graphite composites including local field enhancement are analyzed. A model of the low-field emission based on quantum well effect at the diamond/graphite interface is proposed and discussed. (C) 2001 American Vacuum Society.

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: 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.
