Most of the traditional photocatalytic hydrogen productions were conducted under room temperature. In this work, we selected nonplasmonic Pt metal anchored on TiO2 nanoparticles with photothermal activity to explore more efficient hydrogen production technology over the whole solar spectrum. Photothermal experiments w…
Zinc Oxide nanoparticles were synthesized by microwave assisted hydrothermal method using Zinc Nitrate Hexahydrate (ZnNO3.6H2O) as a starting material. Polyaniline / Zinc Oxide (PANI/ZnO) nanocomposite
The paper refers to structural and magnetic properties of the (Fe80Nb6B14)1−xDyx (x = 0.08, 0.10, 0.12, 0.16) bulk nanocrystalline alloys prepared by making use of the vacuum suction casting technique. The samples are in a form of rods with different diameters d = 1.5, 1, and 0.5 mm. The phase structure was investigat…
The aim of this study was to investigate and compare the surface characteristics and initial bioactivity of ceria-stabilized zirconia/alumina nanocomposite (NANOZR) with those of yttria-stabilized zirconia (3Y-TZP) and pure titanium (CpTi) following the use of three surface modification methods; polishing, sandblastin…
Abstract We present studies of the enhancement of spin-wave intensity and thickness dependence of spin-wave frequency in V 2 O 3 thin films using Raman spectroscopy. Our results show that the intensity of spin-wave at ~450 cm −1 can be enhanced with a 633 nm laser rather than a 514 nm laser. The enhancement of spin-wa…
We report improvement of terahertz (THz) wave radiation for Si-based catalyst-free InAs nanowires (NWs) by simple dipping into tap water (DTW). In addition, the possibility of using InAs NWs as a cost-effective method for biomedical applications is discussed by comparison to bulk InAs. The peak-to-peak current signals…
The dielectric property and percolated behaviour of polymer matrix composites largely depend on the morphology of conductive fillers and external stimulations especially when the composites are processed by melting blending and extrusion‐injection way. In this study, the poly(methyl methacrylate) (PMMA) matrix composi…
Abstract Solution‐state Overhauser dynamic nuclear polarization (ODNP) at moderate fields, performed by saturating the electron spin resonance (ESR) of a free radical added to the sample of interest, is well known to lead to significant NMR signal enhancements in the steady state, owing to electron–nuclear cross‐relax…
Abstract Charge‐transfer (CT) complexes of near‐infrared absorbing systems have been unknown until now. Consequently, structural similarities between donor and acceptor are rather important to achieve this phenomenon. Herein, we report electron donors such as non‐fused diporphyrin‐anthracene (DP), zinc diporphyrin‐ant…
A new series of symmetrical S-shaped oligomers 4,4′-bis[(5-cholesteryloxycarbonylpentyl alkoxy)hexyloxy]biphenyl consisting of outer spacers –(COCH2)n– as well as an inner spacer –(CH2)6– has been synthesised. Their liquid crystalline properties and phase transition temperatures with associated enthalpy changes are re…
2‐Hydrazinobenzothiazole and 2‐furaldehyde diethyl acetal were connected to complementarily functionalized tin sulfide clusters, with coupling of an acetal to a hydrazine‐functionalized cluster being so far without precedence. Neither ethers nor an N,S combination of heteroatoms has so far been present in the ligand s…
We propose a promising method to fabricate controllable anisotropic morphologies in which the slit-based spatial focusing of femtosecond laser is used to create an elliptical-shaped intensity distribution at focal plane, inducing elliptical-shaped morphology with micro/nano-dual-scale structures. Our study shows that…
This work evaluates the efficiency of sugarcane bagasse-based sorbents in the sorption of oil from engine washing wastewater. The sorbents were obtained from sugarcane bagasse in the natural form (SB-N) and modified with either acetic anhydride (SB-Acet) or 3-aminopropyltriethoxysilane (SB-APTS). The results showed th…
Maintaining low and smooth impedance over a wide range of frequency is one of the main issues in designing high-speed digital systems or mixed signal integrated circuits. Cavity resonances of a printed circuit board coupled with discontinuous return current paths, series inductance of the power distribution network, a…
Numerical study of atmospheric ice accretion on circular cylinder is carried out to understand the relation between cylinder diameter and resultant ice accretion. To validate the numerical model, results are compared with the experimental data and a good agreement is found. Numerical study shows that change in cylinde…
Abstract Dilatometry is widely used in the investigation of phase transformation in steels, not only by research laboratories but also by most steel makers. Its application includes the determination of CCT and TTT diagrams, and more generally the investigation of phase transformation kinetics under controlled tempera…
Form fluctuations of microemulsion droplets are observed in experiments using dielectric spectroscopy (DS) and neutron spin echo spectroscopy (NSE). Previous work on dioctyl sodium sulfosuccinate based water in oil microemulsions in the droplet phase has shown that adding a water soluble polymer (Polyethylene glycol M…
Abstract The optimization of the reaction conditions (solvent, reaction time, and aminating agent) for the synthesis of 1‐amino‐2,4‐dinitroimidazole (3) by monitoring the reaction with online infrared spectroscopy is reported in this study. First, the thermal characteristics of 3 were studied by using differential sca…
Antithrombin deficiency is associated with increased risk of venous thrombosis. In certain families, this condition is caused by pathogenic polymerization of mutated antithrombin in the blood. To facilitate future development of pharmaceuticals against antithrombin polymerization, an improved understanding of the poly…
We reported the characteristics of p‐type tin‐oxide (SnO) thin film transistors (TFTs) upon illumination with visible light. Our p‐type TFT device using the SnO film as the active channel layer exhibits high sensitivity toward the blue‐light with a high light/dark read current ratio (Ilight/Idark) of 8.2 × 103 at a ve…
