Abstract The effects of hole doping and strain on the electronic and magnetic properties of a single layered TiO 2 nanosheet were investigated here. It is found that the spontaneous magnetism can be introduced in all systems doped with low valence metal, indicating holes are the key fact to trigger local magnetic mome…
Abstract Unlike traditional catalysts, a Cu(II) catalyst incorporated onto a new pyridine based porous organic polymer linked by carboxamide functionality has been developed by impregnation method. Materials are characterized using FT‐IR, solid‐state NMR, PXRD, SEM, TEM techniques. The uniform confinement effect of th…
Looking ahead to final disposal of high-level radioactive waste arising from further utilization of nuclear energy, the effects of high burn-up of light-water reactors (LWR) with UO2 and MOX fuel and extended cooling period of spent fuel on waste management and disposal were discussed. It was assumed that the waste lo…
Commercial purity Mg, Mg-RE alloys ZE10A (UNS M11600), and EV31A (UNS M12310) were evaluated in the as-received condition for potential application as anode for Mg-air battery. Anodic and cathodic polarization studies were performed in 0.6 M NaCl, 0.5 M NaNO 3 and 0.1 M Na 2 SO 4 electrolytes. Hydrogen evolved during…
This study investigated the effect of moisture absorption on the mechanical performance of polyurethane sandwich composites. The core material was a closed cell polyurethane foam. Face sheets were made of E-glass/polyurethane composite laminates. Vacuum-assisted resin transfer molding process was used to manufacture s…
Ever since the more-than-decade-old discovery of application of mechanical exfoliation to obtain graphene, this 2-dimensional material was known for its soaring promise in various applications, owing to its excellent properties. Graphene, most popularly grown on metallic substrates by chemical vapour deposition, needs…
Mechanical properties of polymer nanocomposites depend primarily on nanointerphases as transitional zones between nanoparticles and surrounding matrices. Due to the difficulty in the quantitative characterisation of nanointerphases, previous literature generally deemed such interphases as one-dimensional uniform zones…
Syntheses and applications of mussel-inspired polymeric materials have gained a foothold in research in recent years. Mussel-inspired chemistry coupled to Michael addition and Schiff’s base reactions was the key success for this intensive research. Unequivocally, The basic building brick of these materials is catechol…
In this study, a Ti-diamond-Ti structured ultraviolet photodetector was fabricated on a homoepitaxial diamond layer with an oxygen-terminated surface. The properties of the Ti/diamond schottky contact were measured using X-ray photoelectron spectroscopy, and the barrier height was found to be 1.15 eV. At a bias of 3 V…
Carboxymethyl cellulose (CMC) was prepared from Gliricidia sepium and Cola gigantea cellulose with yields of 1.59 g/g and 1.76 g/g, respectively. The pH of the products were weakly acidic (6.47 and 6.54, respectively). The sodium chloride content was 0.22 for C. gigantea CMC and 0.27 for G. sepium CMC, while the degre…
Abstract A well‐defined interface between CuO x film and TiO 2 is constructed as a model for elucidating the interfacial charge transfer (IFCT) process that occurs during photocatalysis. Spectroscopic analysis revealed strong blue light absorption at 2.7 eV in this film system. Based on photoemission spectroscopy and…
Abstract The ever‐growing global energy demand and rapid depletion of fossil fuels on day‐to‐day life drive researchers to think about an alternate and efficient storage system. Supercapacitors have drawn considerable attention due to their moderate energy and power densities than batteries and capacitors respectively…
Abstract Two‐dimensional (2D) carbon nanomaterials possessing promising physical and chemical properties find applications in high‐performance energy storage devices and catalysts. However, large‐scale fabrication of 2D carbon nanostructures is based on a few specific carbon templates or precursors and poses a formida…
Abstract In this paper, polyaniline‐zinc oxide (PANI‐ZnO) nanocomposites (NCPs) were prepared by in‐situ chemical polymerization process. The prepared PANI‐ZnO was characterized by FTIR, XRD, SEM, laser size tester, XPS, UV‐Vis DRS and PL. The photocatalytic ability was evaluated for the degradation of methylene blue…
The structures of the liquid crystal (LC) molecules have a key role in impacting the electro-optical performance of a polymer dispersed liquid crystal (PDLC) film. In this paper, the relationship between the LC molecular structures and the electro-optical properties of PDLC films is investigated based on an unexplored…
Room temperature electron mobility of >100 cm 2 V –1 s –1 is achieved for a few-layer MoS 2 transistor by use of a polyanionic proton conductor as the top-gate dielectric of the device. The use of a proton conductor that inherently exhibits a cationic transport number close to 1 yields unipolar electron transport in t…
ABSTRACT: Surface chemistry of regenerated all-wood-biopolymer fibers that are fine-tuned by composition of cellulose, lignin and xylan is elucidated via revealing their surface energy and adhesion. Xylan additive resulted in thin fibers and decreased surface energy of the fiber outer surfaces compared to the cellulos…
Fe supported catalysts show great promise for enabling practical environmental catalysis, exemplified by the catalytic wet peroxide oxidation (CWPO) process. In order to mitigate the Fe leaching issue, a strategy of assembling zeolitic coatings with intraframework Fe (ferrisilicate) on SiC foams was developed, showing…
Mucins, the main component of the mucus secretions of goblet and epithelial cells, are known for exhibiting a different behaviour in accordance with their surrounding environment (i.e. among others the environmental pH), which induces a drastic change in their measured mechanical properties. In this work, we have firs…
In this work, an azido-modified dopamine derivative was synthesized and subsequently used to postfunctionalize the surface of nanoporous poly(styrene)- block -poly(4-vinylpyridine) diblock copolymer membranes. On the basis of this layer a continuative modification was realized by performing a “Click” reaction, namely,…
