Abstract Optical technologies in the long‐wave infrared (LWIR) spectrum (7–14 μm) offer important advantages for high‐resolution thermal imaging in near or complete darkness. The use of polymeric transmissive materials for IR imaging offers numerous cost and processing advantages but suffers from inferior optical prop…
The paper describes the magnetoelectric (ME) effect in a gradient laminate structure consisting of a LiNbO 3 /Ni/metglas multilayer based on a bidomain lithium niobate single crystal with a Y + 128° cut. The main purpose of the work is to obtain a self‐biased structure. A theoretical and experimental study is conducte…
Carbon microfibers (CMF) has been used as an adsorbent material for CO2 and CH4 capture. The gas adsorption capacity depends on the chemical and morphological structure of CMF. The CMF physicochemical properties change according to the applied stabilization and carbonization temperatures. With the aim of studying the…
Hot deformation behaviors of the Twin-roll Casted (TRCed) AZ31 magnesium alloy were studied by uniaxial compression tests under a temperature range of 473–673 K and strain rate of 0.001–1s−1. The effects of the temperature on activation energy and recrystallization were discussed, and the degree of DRX had also been d…
arrest, and inhibited TNF-α and IL-2 production.
Single‐walled carbon nanotubes (SWCNTs) with a mean diameter of 1.4 nm are filled with rubidium iodide. The filling of nanotubes is proved by high‐resolution scanning transmission electron microscopy. The chemical composition of the filler is confirmed by X‐ray photoelectron spectroscopy (XPS). The electronic properti…
Composites with high density polyethylene (HDPE) and poly(lactic) acid (PLA) matrix have been tested to analyze the effect of natural fillers (wood flour, recycled wastepaper and a mix of both fillers) and temperature on polymer degradation. Composting tests have been performed in both mesophilic (35 °C) and thermophi…
To investigate the H2 purification mechanism of V membranes, we studied the adsorption, dissociation, and diffusion properties of H in V, an attractive candidate for H2 separation materials. Our results revealed that the most stable site on the V (1 0 0) surface is the hollow site (HS) for both adsorbed H atoms and mo…
Silk fibroin, which is derived from sericin through degumming, is mainly used as a biomaterial. However, interest in functional verification and industrial applications of sericin has been growing for several years. We used ultrasonication to simplify the extraction process of the silk peptide under low salt condition…
Three constructional solutions of coulters used in cultivators were assessed with regard to their wear resistance in soil. The coulters were installed on a four-beam cultivator used for cultivation of loamy-sandy soils with humidity typical for the summer season. It was found that the amount of thickness reduction of…
A detailed theoretical study, based on density functional theory (DFT) with GGA-PBE, of electronic, optical and structural properties of calcium (Ca) and barium (Ba)-doped SrZrO3, is presented. The doping influence on the electronic structure and consequently optical properties are analysed and explained with TDOS and…
This work demonstrates a kind of lignin-derived carbon/zinc oxide (LDC/ZnO) composite prepared through a facile electrostatic self-assembling carbonization process. Solidification of the lignin/zinc oxalate precursor results in zinc oxalate (ZnC 2 O 4 ) crystalizing in lignin. The crystalized ZnC 2 O 4 particle acts a…
Abstract This review looks at the main types of magnetic Barkhausen noise (BN) probes that have been developed. The aim of this review is to summarize the existing knowledge of magnetic Barkhausen noise probes and the magnetic modelling of them. The BN probes have been the focus of many previous studies, but no suffic…
This article presents the effects of pineapple leaf (PALF), napier, and hemp fibres as filler on the scratch resistance of epoxy composites. In particular, it explores the effect of these natural fillers on the horizontal load, coefficient of friction (COF), penetration depth, fracture toughness, scratch hardness, bri…
Understanding nucleation phenomena is crucial across all branches of physical and natural sciences. Colloidal nanocrystals are among the most versatile and tunable synthetic nanomaterials. While huge steps have been made in their synthetic development, synthesis by design is still impeded by the lack of knowledge of r…
A complementary split-ring resonator (CSRR) based metamaterial is designed and investigated in this paper for microwave applications with effective medium ratio. This CSRR is the modification of the conventional split-ring resonator. Three square split-ring resonators (SSRR) are interconnected with a strip line as wel…
We develop intuitive metrics for quantifying complex nucleating systems under confinement. These are shown to arise naturally from the analysis of the topological ring network, and are amenable for use as order parameters for such systems. Drawing inspiration from qualitative visual inspection, we introduce a general…
The abstract of Phys. Rev. Lett. 121, 157001 (2018) claims to "demonstrate, using ab initio computations, a new trend suggesting that the cuprates with stronger out-of-CuO$_{2}$-plane chemical bonding between the apical anion (O, Cl) and apical cation (e.g., La, Hg, Bi, Tl) are generally correlated with higher $T_{c\,…
The conducting states, recently discovered at the surface of two special class of insulators -- topological insulators and topological crystalline insulators - are distinguished by their insensitivity to local and non-magnetic surface defects at a level of disorder, sufficiently small to be described within the pertur…
The acoustic phonons in the organic-inorganic lead halide perovskites have been reported to have anomalously short lifetimes over a large part of the Brillouin zone. The resulting shortened mean free paths of the phonons have been implicated as the origin of the low thermal conductivity. We apply neutron spectroscopy…
