A liquid crystal polymer (LCP) was used to improve the physical properties of glass fiber reinforced polypropylene (GFRPP). The LCP was beneficial to improve the mechanical and heat resistant properties of the GFRPP/LCP composite. Compared with the GFRPP with 30% (w%) glass fiber (GF), the yield strength and the impac…
Abstract The presented study is the original analysis of hydrogen flow in channels with heterogeneous physical‐chemical reactions. It provides the possibility to evaluate, calculate and predict unknown constants of heterogeneous reactions, using experimental data on dissociation at low pressures. It can be the base of…
ABSTRACT Soft and tacky mass recognized as whole coagulum (Cog) and its toluene soluble fraction (TE) obtained through coagulation of latex of Euphorbia caducifolia Haines has been investigated in this article as green tackifier cum multifunctional agent in natural rubber (NR) based gum compounds. It was observed that…
Abstract Shape memory polymers represent a class of polymers that display properties of shape change under stimulus. The presented research focused on material characterization of thermally stimulated shape memory polymers, more specifically heat shrinkable bands often used as packaging in the food and the medical ind…
The present manuscript is aimed at the development of the protective layer for metal components for outdoor applications such as telecommunication components. Multiwalled carbon nanotubes at varying weight (from 0.5% to 5.0% by weight) were incorporated into newly developed 50/50 blend of acrylonitrile styrene acrylat…
Oxalate exists in plant tissue in the form of soluble and insoluble salts. Determination of the oxalate content in a raw material is important for controlling oxalate scaling during the pulping and papermaking processes. In this study, oxalate extraction and determination of the total and soluble oxalate contents in s…
We developed sandwich ultraviolet photodetectors by a radio frequency magnetron sputtering method. As expected, the performances of the optimized ZnO/Au/ZnO sandwich photodetectors are much better than that of a metal-semiconductor-metal structure through combing high responsivity (enlarged ~60 times) and low dark cur…
Chemical graphene nanoribbons (CGNRs), a new type of quantum-confinement graphene nanostructure with tunable electrical conduction channels and bandgaps, are fabricated by chemically narrowing the conduction channels of the graphene based on an edge-selective covalent reaction. Such CGNRs behave as semiconductors with…
This review highlights recent interests and applications of disulphide and thiol chemistry in creating contemporary macromolecular designs. Due to the chemical nature of disulphides and thiols a wide range of chemical species react with these functional groups to yield a variety of polymers extending their application…
Aerosols created by the vaporization of simulated spent nuclear fuel (simfuel) were produced by laser heating techniques and characterised by a wide range of post-analyses. In particular attention has been focused on determining the fission product behaviour in the aerosols, in order to improve the evaluation of the s…
The effect of Ce substitution for (Nd,Pr) on structure, microstructure, and magnetic properties of [(Nd0.75Pr0.25)1-xCex]11.65Fe82.75B5.6(x = 0-0.5) melt-spun powders has been studied. It has been found that all Ce-substituted powder samples retain the R2Fe14B (R = Nd, Pr, Ce) single-phase structure with a similar gra…
Borates are among a class of compounds that exhibit rich structural diversity and find wide applications. The formation of edge-sharing (es-) BO4 tetrahedra is extremely unfavored according to Pauling's third and fourth rules. However, as the first and the only es-borate obtained under ambient pressure, es-KZnB3O6 sho…
An imidazole-based antifungal drug, namely ketoconazole (KETO), was evaluated as a corrosion inhibitor for steel in 1 M hydrochloric acid by electrochemical impedance spectroscopy (EIS) and gravimetric method. Atomic force microscope was also utilized to investigate the corrosion inhibition properties and film formati…
Density functional theory was employed to design enhanced amorphous NbO 2 thermoelectrics. The covalent-ionic nature of Nb–O bonding is identical in amorphous NbO 2 and its crystalline counterpart. However, the Anderson localisation occurs in amorphous NbO 2 , which may affect the transport properties. We calculate a…
Manganese vanadate nanobelts have been synthesised by a simple hydrothermal process using polymer polyvinyl pyrrolidone as the surfactant by adjusting the pH value. The X-ray diffraction, selected area electron diffraction and the high-resolution transmission electron microscopy (TEM) show that the manganese vanadate…
Elaboration in a controlled way of large-area and efficient plasmonic substrates is achieved by combining sputtering of silver nanoparticles (AgNPs) and plasma polymerization of the embedding dielectric matrix in an axially asymmetric, capacitively coupled RF discharge maintained at low gas pressure. The plasma parame…
The Cu-doping effect on the lattice and magnetic properties in Mn3Ni1−xCuxN (x = 0, 0.3, 0.5, 0.7, 1.0) was extensively investigated. We observed that the Cu-doping at the Ni site complicated the magnetic ground states, which induced the competition of antiferromagnetic and ferromagnetic interactions. Spin-glass-like…
Isotropic acoustic cloaking is proposed using density-near-zero materials for extraordinary sound transmission. The cloaking cell is made by single-piece homogeneous elastic copper, which can be detached and assembled arbitrarily. We theoretically and numerically demonstrate the cloaking performance by deploying densi…
A new technique for the fabrication of arrayed waveguide gratings on upconversion luminescent layers for flexible transparent displays is reported. Ho 3+ ‐ and Yb 3+ ‐codoped NaYF 4 nanoparticles are synthesized by hydrothermal techniques. Transparent films consisting of two transparent polymers on the NaYF 4 nanopart…
Current evidence of engineered nanomaterials' (ENM) toxicity has led to a latent concern about hazards for both humans and the environment. For this reason, some efforts have been made to suggest frameworks or other guidance to regulate ENM handling; however, the real exposure risk to humans has not been well establis…
