A theoretical method named as quantitative structure and property relationship (QSPR) was used to investigate corrosion inhibition efficiency of benzimidazole and its derivatives on mild steel in 1 M hydrochloric acid. Some electronic, spatial and thermodynamic properties were selected as descriptors to build relation…
The study reports the thermal and growth investigation of binary alloys represented by nicotinamide with -naphthol. The solid-liquid equilibrium data determined by Thaw-melt method with their corresponding compositions construct the solid-liquid phase diagram which suggests simple eutectic behaviour is followed by the…
The mesh interconnection network has been preferred by the Network-on-Chip (NoC) community due to its simple implementation, high bandwidth and overall scalability. Most existing mesh-based NoC designs operate the mesh at the same or lower clock speed as the processing elements (PEs). Recently, a new source synchronou…
Barium metatstannate (BaSnO3) nanoparticles were synthesized successfully using a facile microwave solvothermal route followed by further heat-treatment. Well-crystallized BaSnO3 nanoparticles were formed after heat-treatment at 800 ºC for 3 h showing a fine and homogeneous morphology with particle sizes of 60-80 nm.…
Through the study of three grades of low polymerization degree poly(vinyl chloride) resins, the molecular weight distribution of low polymerization degree PVC resins was influenced by the particle size. The number of sub micro particles in low polymerization degree poly(vinyl chloride) resin is related to the molecula…
Hydroxyethyl cellulose (HEC) grafting poly(caprolactone) (PCL) copolymer (HEC-g-PCL) was successfully synthesized by the protective technology of trimethylsilyl group. The poly(caprolactone) was grafted onto hydroxyethyl cellulose after the partial hydroxyl groups were firstly protected with trimethylsilyl group, then…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
Electrochemical capacitors use activated carbons for both positive and negative electrodes that show a non-faradaic, double-layer charge-discharge mechanism in a symmetric configuration. Thus electrochemical capacitors are efficient energy storage devices that exhibit long lifespans and extremely rapid charge-discharg…
A series of novel blue light-emitting 1-alkyl-2-substituted benzimidazoles (4a-4g) were synthesized by reactions of the 2-substituted benzimidazoles (3a-3e) with ethyl bromide or n-butyl bromide as electrophilic reagent. Compounds 3a, 3c, 3e were synthesized by the condensation of 1a-1c with 1,2-diamino benzene o-phen…
Les prises de position des organisations syndicales, européennes ou françaises, sur les nanotechnologies permettent de mettre au jour un déplacement de l’agir syndical. Le syndicalisme a classiquement inscrit son approche des risques au travail dans l’espace des relations professionnelles en accompagnant le « progrès…
x Ga 1-x N, Si substrate, wafer curvature Device-oriented GaN layers have been grown with Al x Ga 1-x N buffer structures as a bottom layer on 8 in. Si substrates using a commercial high-throughput metal organic chemical vapor deposition (MOCVD) system. The effect of the V/III ratio on the growth of AlN nucleation lay…
In this video we show how to enumerate polyominoes on twisted cylinders, and explain how to use them for setting lower bounds on the asymptotic growth rate of polyominoes in the plane.
An unexpected space debris population was recently identified as being very high area-to-mass ratio (HAMR) \ndebris in geostationary orbit (GEO). Scientists hypothesised about their origins, consensus is that these objects are \nmulti-layer insulation (MLI), separated from the spacecraft due to fragmentation events or…
In this study functionalized SBA-15 mesoporous silica materials have been synthesized through a simp le co-condensation approach of bis-(3-(t rimethoxyosily l)propyl) amine (BTPA) and tetraethyl orthosilicate (TEOS) using xy lene like swelling agent, amphih ilic trib lock-copolymer (PEO-PPO-PEO) Pluronic P123 as struc…

We studied the relationship between microstructural change and the evolutions of two nonlinear acoustic characterizations with electromagnetic acoustic resonance (EMAR) during creep in Cr-Mo-V steels and the correlation between two nonlinear acoustic characterizations. One was higher harmonic generation and other reso…
表面增强拉曼散射（surface enhanced Raman scattering，SERS）是通过吸附在粗糙金属表面或金属纳米结构上的分子与金属表面发生的等离子共振（SPR）相互作用而引起的拉曼散射增强现象，是一种高灵敏的探测界面特性和分子间相互作用的光谱手段。文章归纳总结了近年来常用的SERS衬底的制备方法（溶液中的金属溶胶（MNPs in suspension）、金属纳米粒子的自组装（self-assembly）、模板法（Template method）和纳米光刻法（Nanolithographic）等；综述了这些衬底的表面增强拉曼特性；着重介绍了SERS增强在环境监测和生物医学应用上的最新国内外研究动态。目前已经能够实现…
The measurement and evaluation of carbon budget of marine industry is the basis for promoting green and efficient development of marine economy under the goal of carbon neutrality. We constructed a carbon accounting system for the marine industry in Jiangsu Province, and assessed carbon efficiency and neutrality. The…
Ceria-zirconia-terbia solid solutions were synthesized by co-precipitation method. The powders were characterized by XRD, colorimetric assessment and UV-Vis diffuse reflectance. A solid solution phase structure was obtained for all of the samples heated at 900°C and belongs to cubic fluorite structure or distorted flu…
The phase diagrams of CdSe1-xSx alloys were calculated for three different crystal structure types: wurtzite (B4); zinc-blende (B3); and rocksalt (B1). Ab initio calculations of supercell formation energies were fit to cluster expansion Hamiltonians, and Monte Carlo simulations were used to calculate finite temperatur…
