The interaction between graphene and substrates may destroy the intrinsic properties of graphene, and reduce the potential applications of graphene in electronic devices. Here, we use first-principles calculations to explore the possibility of a graphitic ZnO layer as an ideal substrate for graphene. Taking graphitic…
INTRODUCTION: Plant latex is a natural source of biologically active compounds and several hydrolytic enzymes responsible for their diverse health benefits. Recent past has witnessed substantial progress in understanding their supplementary industrial and pharmaceutical utility. Calotropis gigantea is one of the impor…
A nanostructural thin film is one of the highly exploiting research areas particularly in applications in sensor, photocatalytic, and solar-cell technologies. In the past two decades, the integration of glancing-angle deposition (GLAD) technique to physical vapor deposition (PVD) process has gained significant attenti…
The present study investigated the potential of a novel micropatterned substrate for neocartilage formation. Articular chondrocytes were cultured on poly( ɛ-caprolactone) materials whose surfaces were either flat or honeycomb-patterned. The latter was prepared using a novel self-organization technique, while the forme…
Synthesis of a graphene hydrogel, in which the elastic modulus can be changed from ∼10 to ∼105 Pa and the electrical conductivity can be controlled in a range from ∼0.01 to ∼6 S cm−1 by carefully adjusting the graphene content, allowing for direct processing and patterning of graphene for many electrical applications.
O presente trabalho busca avaliar o comportamento de compósitos que contêm em sua formulação um biopolímero originário de indústrias da agricultura sustentável. O biopolímero selecionado, poli(ácido lático), (PLA) e um polímero termoplástico (poliuretano), (TPU), foram misturados a fibras naturais (madeira e coco). Em…

A porous fiber of AIE-active PMMA fabricated through the electrospinning technique shows exceptional fluorescence. The green fluorescence of porous fibers can be switched off and on by the adsorption and desorption of silicon or bean oil.
A mesoporous manganese oxide/carbon nanotube composite was successfully synthesized <italic>via</italic> interfacial surfactant assembly. The electrochemical utilization of MnO <sub>2</sub> was greatly improved due to the synergetic effect of the mesoporous structure and the CNTs.
In order to create a new mechanofluorochromic material, title compound (BMAAP) was designed and synthesized. BMAAP was found to readily form an amorphous glass with a glass transition temperature of 9 °C and exhibit solvatofluorochromism in solution. BMAAP was also found to exhibit fluorescence both in crystalline sta…
The Kubo formula for the electrical conductivity of per stratum of few-layer graphene, up to five, is analytically calculated in both simple and Bernal structures within the tight-binding Hamiltonian model and Green's function technique, compared with the single-layer one. The results show that, by increasing the laye…
A quantum dot conjugated to a dye through an experimentally simple process of self-assembly exhibits an enhanced emission when the dye is attached, and this effect is pH-sensitive.
A series of coordination compounds Htpim (1), {[Zn(Htpim)2(H2O)2]·(NO3)2·7.5H2O}n (2), {[Zn(Htpim)2(H2O)2]·(CH3COO)2·5H2O}n (3), {[Cd(Htpim)2(NO3)2]·9H2O}n (4), {[Cd(Htpim)2(CH3COO)(H2O)]·(CH3COO)·3H2O}n (5) were assembled from different metal(II) ions (ZnII for compounds 2 and 3, and CdII for compounds 4 and 5) and a…
Thermal coagulation therapy using powdered magnetic materials in an alternating (AC) magnetic field has been expected as a treatment of cancerous tissues. For nano-sized superparamagnetic particles, the magnetic energy is mainly converted to a heat generation ability by the rotation of the magnetic moment (Néel relaxa…
Vitrification is one of the recommended immobilization routes for nuclear waste, and is currently implemented on an industrial scale in several countries, notably for high-level waste. To optimize and extend the scope of nuclear waste vitrification, research is being conducted to specify suitable glass formulations an…
The effects of five types of metal nanoparticles, gold (Au), silver (Ag), platinum (Pt), Au-polyvinylpyrrolidone (PVP) colloid, and Pt-PVP colloid, and two types of hydrophilic carbon black on cell behavior were examined. Stable nanoparticle dispersions were prepared and applied to the culture medium of human keratino…
The molar volumes of binary M–Si (M=Fe, Ni, and Ge) alloys in a liquid state were obtained from their densities measured using electromagnetic levitation coupled with a static magnetic field. We have systematically analyzed the molar volume as a function of composition. Although the concentration dependence of the mol…
In this study, effects of operating conditions on the electrochemical reduction of CO2 on solid oxide electrolysis cell (SOEC) were systematically investigated. Experimental results revealed that the reducing gas can influence the behavior of Ni–YSZ cermet cathode. Supply of hydrogen as a reducing gas was found to be…
Single component nanofiller has shown some limitations in its performance, which can be overcome by hybrid nanofillers with two different components. In this work, montmorillonite (MMT)/graphene oxide (GO) hybrid nanofillers were formed by self‐assembly and then incorporated into the polyacrylonitrile (PAN) nanofibers…
The extrusion of ultra high molecular weight polyethylene (UHMWPE) fibres cannot be achieved by conventional extrusion processes due to its very high melt viscosity. To overcome this limitation, UHMWPE is first dissolved in a petrochemical to form a gel before extrusion. The petrochemicals used to dissolve the polymer…
