Hydrogenation has been recently developed as an approach to improve the visible-light response of titanium dioxide(TiO2);however,the effect of hydrogenation on the electronics and optical absorption of anatase TiO2has been widely debated.In this work,the electronic structures and optical properties of hydrogenated TiO…
Strip-like FeCo films were patterned by a traditional lithograph process from intrinsically isotropic continuous FeCo films. The strip-patterned FeCo film shows a strong in-plane uniaxial magnetic anisotropy with easy axis along the length direction of the strip. The angular dependences of remanence ratio, switching f…

The EPDM(EPDM) zinc ionomer(EPDM-g-MAZn) grafted with maleic anhydride(MAH) was used as modifying agent in the PP/IFR system.The flame retardant mechanism of the EPDM-g-MAZn and its effects on the mechanical properties of PP/IFR were studied.Flame retardancy was good and tensile strength remained the same with the add…
在扶手椅和之字形边 graphene 带子的短暂的热传导由与 1 的持续时间的本地加热搏动了 ? ps 用 nonequilibrium 被学习分子的动力学模拟。结果证明热脉搏使显示 non-Fourier 热传导的二个波浪激动。二个波浪之一是声波(第一个声音) ，它有宏观的动量并且以声音的速度宣传。其它是一个热波浪(第二个声音) ，其繁殖速度是 \(1/\sqrt 3 \) 健全速度。热脉搏激动的声波是一个纵的波浪，其精力仅仅在纵的方向被搬运。热脉搏激动的热波浪被横向的格子颤动产生，与仅仅有横向的部件的精力。短暂的热传导的观察 anisotropy 建议系统在热脉搏的繁殖期间处于一个非平衡状态。进一步统计的分析证明热脉搏精力的排…
The corrosion inhibition effect of the Bohea leaves exctrative on carbon steel in 1. 0 mol /L HCl solution was investigated by using potentiodynamic polarization and electrochemical impedance spectroscopy. The results indicate that the Bohea leaves extractive exhibits good corrosion inhibition effect on carbon steel.…
WS2 and WS2/Zr self-lubricating soft coatings were produced by medium-frequency magnetron sputter- ing, multi-arc ion plating and ion-beam-assisted deposition technique on the cemented carbide YT15 (WC ? 15 % TiC ? 6 % Co) substrates. Microstructural and funda- mental properties of these coatings were examined. Slidin…

A general, rapid and solvent-free approach is proposed to fabricate nanostructured polymer surfaces by coupling ultrasonic vibration and anodized aluminum oxide templating. With our approach, hollow nanorods or nanofibers with controlled diameter and length are prepared on polymer surfaces. The whole fabrication proce…
Rhodium- and iron phosphate-based catalysts are by far the most promising catalysts for oxy-bromination of methane(OBM) reaction. However, most literature reported either Rh- or FePO4-based catalysts, and the results were rarely studied in a uniform environmental condition. In this report, comparative study was conduc…
A bifunctional organic-inorganic mesoporous titanium phosphonate hybrids containing acidic and alkali centers, which could simultaneously remove multiple hazardous compounds in mainstream cigarette smoke, was synthesized by an autoclaving process combined with the evaporation-induced self-assembly(EISA) strategy. The…
粒子和更好的热转移的更同类的分发从低压力落下和高热的电导率发源原文如此起泡沫支持的结构化的催化剂可能能说明他们的改进效率和稳定性。鉴于他们的极大地减少的费用和许多延长生活，这些新奇结构化的 C/Au 催化剂能潜在地在 VCM 工业化被使用，这被相信。
Reaction of [MoO2(Acac)2] (Acac = acetylacetonate) with two similar hydrazone ligands in methanol yielded two mononuclear molybdenum(VI) oxocomplexes with general formula [MoO2(L)(CH3OH)], where L = L 1 = (4 nitrophenoxy)acetic acid [1 (3 ethoxy 2 hydroxyphenyl)meth ylidene]hydrazide (H2L 1) and L = L2 = (4 nitropheno…
Nickel and silver particles were prepared by using sol-gel auto-combustion method under N2 atmo- sphere where lactic acid was applied as chelating agent. The synthesis of nickel particles was carried out at various pH conditions (2-7), resulting in the face-centered-cubic or hexagonal-close-packed crystalline nickel p…
