Photocatalysis has become a fast wastewater treatment technology. Herein; ternary mixed oxide catalyst, phenol pollutant and visible light were used. The new MnO2/Al2O3/Fe2O3 nanocomposite was synthesized by sol-gel method using Fe(NO3)3.9H2O, Al(NO3)3.9H2O, MnO2, 1-C4H9OH and 68 % HNO3 precursors in aqueous solution…
It is found that the Kerr constant of the aged transformer oil increases relative to that observed in the fresh one. Moreover, the temperature dependence of the Kerr constant of the aged oil is found to be stronger than in the fresh one. The results obtained allow to consider the use of Kerr effect measurements in mon…
Electrospinning technique was used for the fabrication of poly （ vinyl alcohol ） （ PVA ） / regenerated silk fibrnin （ SF ） composite nanofibers, loaded with ciprofloxacin HCI （CipHCI） as a wound dressing. Electrospun PVA/SF/CipHCI composite nanofibers were stabilized against dissolving in water by heating in an oven a…
Abstract: This work introduces important properties of some new derivatives of nitrotetrazolyl-imidazole as high nitrogen energetic compounds, which are evaluated and discussed using some reliable models. The predicted properties are also compared with 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX). It is shown…
In this paper five TiO2 powders prepared by sol-gel technique were analyzed being into consideration the modification of method of synthesis applied. As a precursors titanium (IV) buthoxide (TBOT) or titanium (IV) isopropoxide (TIPO) were used. The size of obtained pure TiO2 particles (called in paper TiO2-1 ÷ TiO2-5)…
The Mechanistic-Empirical Pavement Design Guide (M-E PDG) is becoming the state-of-the-practice in both newly constructed and rehabilitated pavement designs. The M-E PDG utilizes semi-mechanistic and semi-empirical models to predict the distresses such as fatigue cracking, rutting and thermal cracking in asphalt pavem…
CuO thin films have been growth on to heated glass substrates by varying substrate temperatures from 280 to 400°C. The effect of the pyrolysis on structural, optical and electrical proprieties of CuO films has been investigated in the present work. Phase analysis was carried out using Micro-Raman scattering. The optic…
The cosmetics industry covers a very wide spectrum of products: body lotions, shower gels, hand creams, shampoos and conditioners, after shave balsams, shaving foams, foot gels, antiperspirants, moisturizing creams, lip balms, eye care creams, and so on. Then there is the whole range of make-up products: eye shadows,…
Optimization of factors influencing the experiments on reactions involving 8 different chelating agents and sol- uble Fe (III)/Fe (II) salts was carried out to yield chelated iron complexes. A combination of optimized influencing factors has resulted in a Fe chelating capacity of the iron-based desulfurization solutio…
Abstract. Among the requirements of a mechatronic system those related to its smart functions are crucial for an effective design. Smartness is associated to the system capability of self–adapting when the operating conditions change and usually it resorts to the action of the control system. The occurrence of the ‘Sy…
The main neutron shield for the neutron beam line and neutron spectrometer at J-PARC consists of multilayers of iron and ordinary concrete or boric acid resin and ordinary concrete. However, the available space inside the shield will become limited since a multilayer shield must have sufficient thickness to guarantee…
In this paper we have prepared yttrium-doped M-type strontium ferrite SrYxFe(12-x)O19 (x = 0, 0.25, 0.5, 0.75, 1) calcined materials by solid-phase sintering method at 1150 °C for 3 h. Then the calcined materials were pressed for magnets under the condition of oriented magnetic field and sintered in 1295 °C for 3 h. W…
Polyepoxysuccinic acid derivative was synthesized from L-cysteine and polyepoxysuccinic acid a condensation polymer formed by cyclization and polymerization with maleic anhydride.The structure of polyepoxysuccinic acid derivative was characterized by means of FTIR and 13 C NMR.The scale inhibition and corrosion inhibi…

铌离子培植被发现显著地减少磨擦系数并且改善穿 NiTi 形状记忆的抵抗合金。扫描电子显微镜(SEM ) 观察显示在机械擦亮期间在 NiTi 上形成的表面沟在 Nb 离子培植以后被移开。干燥磨擦测试证明植入的 NiTi 取样的 Nb 展出一个更低的磨擦系数，更狭窄穿轨道，少数穿产生的碎片， 46 ?% 62 ?% 减小在穿宽度，并且 29 ?% 49 ?% 减小在与未经治疗的 NiTi 相比穿深度。穿抵抗与事件参数有关，并且 Nb 与 2.5 的事件剂量植入 NiTi ????? 鑟 ? ??? 顥魃 ?????? 鞪? 箖鄮 ?? 苐??????? u ????? “
Ceria was investigated as a catalyst for selective catalytic reduction of NO by NH3.The ceria catalysts were prepared by citric acid method with different calcination temperature.Experimental results showed that the selective catalytic reduction activity of ceria catalyst decreases with increasing calcination temperat…
Fundamental understanding of the complex interactions governing structureproperty relationships in iron-based alloys is necessary to advance ferrous metallurgy. Two key components of alloy design are carbide formation and stabilization and controlling the active deformation mechanism. Following a first-principles meth…
Polymer matrix composites have been applied in components such as helmets and shielding for which toughness is a major requirement. A natural fiber presents interfacial characteristics with polymeric matrices that favor a high impact energy absorption by the composite structure. The objective of this work was then to…
In this paper, the site occupations of H under different mole ratios in interstitials of α -Fe and γ -Fe are studied by the first principles method based on the density functional theory.
