For a system of two spatially separated monoatomic graphene layers encapsulated in hexagonal boron nitride, we consider the drag effect between charge carriers in the Fermi liquid regime. Commonly, the phenomenon is described in terms of an interlayer Coulomb interaction. We show that if an additional electron--electr…
Graphene oxide nanoribbons (GONRs) with a high aspect ratio and high gravimetric density of their edges relative to those of graphene flakes are promising platforms for graphene-based devices. Since the edge chemistry of GONRs determines their final electronic and transport properties, it is important to understand th…
Abstract Typical electrospun polylactic acid (PLA) membranes revealing potential hydrophobicity and inflammation from acid release during degradation are major drawbacks as an ideal guided tissue regeneration (GTR) barrier. This study investigated the in vitro degradation properties of electrospun PLA/beta‐tricalcium…
Lead‐free ( Na 0.53 K 0.45 Li 0.02 )( Nb 0.8 Ta 0.2 ) O 3 ( NKLNT ) was prepared using a conventional cold‐pressing method. A commercial piezoresponse force microscope ( PFM ) was applied to observe the domain structures of NKLNT ceramics. The typical configuration of the ferroelectric domain was analyzed in abnormal…
Transparent films of PMMA (poly methyl methacrylate), PVAc (polyvinyl acetate) and their blends, have been prepared by using a solution-casting technique. The dielectric properties and the electrical conductivity are reported. The frequency and temperature dependence of the dielectric constant, ε′ and tan δ, have been…
Exciton dynamics within the band-edge state manifold of CdSe/ZnS and CdSe/CdS quantum dots (QDs) have been investigated. Low-temperature time-resolved photoluminescence (PL) experiments demonstrate that exciton relaxation is mediated by LO phonons, whereas an acoustic phonon bottleneck is observed for splitting energi…
An extruded Mg–1Mn–1Nd (wt%) (MN11) alloy was tested in tension in an SEM at temperatures of 323 K (50°C), 423 K (150°C), and 523 K (250°C) to analyse the local deformation mechanisms through in situ observations. Electron backscatter diffraction was performed before and after the deformation. It was found that the te…
We evaluated a solvent vapor-sensitive, non-woven fabric made from a biodegradable, poly(lactic acid) (PLA) polymer loaded with multi-walled carbon nanotubes. The sensory properties of the fabric were obtained by optimizing the process parameters for manufacturing the melt-blown, non-woven fabric composed of 98% PLA 4…
In this study, we have developed for the first time a fast and energy-efficient method for the synthesis of PbS nanocrystals with systematic shape evolution from cubic to truncated cubic, cuboctahedral, truncated octahedral, and octahedral structures. The method involves the addition of a small volume of preheated lea…
We report the synthesis of two-dimensional (2D) dendritic Au nanowires (DNWs) with diameters of 100-200 nm in an aqueous solution of long-chain amidoamine derivative (C18AA), which acted as both capping and reducing agent, and the preparation of large 2D DNWs with diameters of 400-700 nm by seeded growth of the origin…
Work in impermeable protective clothing leads to a significant thermal load on its user. Limited heat and moisture transport, which is an effect of using air- and moisture-impermeable coated fabrics in protective clothing, causes a significant increase of the temperature and relative humidity in the undergarment micro…
The acid soluble collagen (ASC) and pepsin soluble collagen (PSC) were extracted from the outer skin of Sepiella inermis and further characterized partially. The yield of ASC was low (0.58% on dry weight basis); whereas the yield of PSC was comparatively more (16.23% on dry weight basis). The protein content in ASC an…
Hagfish slime threads, which make up the fibrous component of the defensive slime of hagfishes, consist primarily of proteins from the intermediate filament family of proteins and possess impressive mechanical properties that make them attractive biomimetic models. To investigate whether solubilized intermediate filam…
Abstract Sisal whiskers (SW) were prepared by acid hydrolysis for subsequent evaluation as reinforcing material for biodegradable matrices of thermoplastic starch (TPS) and TPS/polycaprolactone (TPS/PCL) blends. The acid hydrolyzed SW had dimensions of 5 ± 2 nm in diameter and 210 ± 60 nm in length and 78% crystallini…
The electrical properties of carbon nanostructures have been greatly stimulating to use in the nanotechnology for electronic components. In this paper, we study the AC and DC electrical conductivity responses of multi-walled carbon nanotube films, prepared by the vacuum filtration methods, with noncontact terahertz ti…
High Performance PET/Carbon Nanotube Nanocomposites: Preparation, Characterization, Properties and Applications
A strategy to achieve balanced properties using functionalized carbon nanotubes has been investigated, and its nanocomposite exhibited good performance in mechanical and electrical properties. Polybutyl acrylate (PBA) has been utilized to functionalize multiwalled carbon nanotubes (MWNTs) by in situ atom transfer radi…
We performed first-principles calculations of Co2VAl to determine its electronic and magnetic properties. For this, the density functional-based full potential linearized augmented plane wave method is used. Firstly, volume optimization is done based on generalized gradient approximation to determine the equilibrium l…
A chiral organic nanosheet spontaneously assembled under mild conditions from N, N ′, N ″-tris( n -octyl)benzene-1,3,5-tricarboxamide, which is a C 3 -symmetric supramolecular atropisomer. Similar to the β-pleated sheets of polypeptides, the hydrogen bonded backbone of the chiral sheet does not involve side chains. Th…
Abstract The work deals with the preparation and characterization of elastomer/multiwalled carbon nanotube (CNT) composites. Nitrile‐butadiene‐rubber (NBR), emulsion styrene‐butadiene‐rubber (E‐SBR) with random segment distribution, and solution styrene‐butadiene‐rubber (S‐SBR) having a blocked styrene content were us…
