Every two years the IEEE DEIS selects an individual in recognition of sustained leadership, support, and contributions to the advancement of the field of electrical insulation. This award, which was first given in 1992, is named in honor of the late Eric O. Forster, for his distinguished service on behalf of DEIS. The…
A bureta é um tubo graduado, estreito, com a extremidade inferior alongada, na qual existe uma torneira. É utilizada em posição vertical, para transferir porções de líquido de volume rigorosamente conhecido para outros recipientes, geralmente durante operações de titulação.

Corrosão é a degradação de materiais quando estes são expostos a ambientes reativos (líquidos ou gasosos). Embora o ataque possa ocorrer em metais, semicondutores, isoladores ou polímeros orgânicos, a designação está tradicionalmente associada ao desgaste de metais. Os compostos que resultam de tal degradação são seme…
This research article contains process of RMPA modification into triple band feeler using negative media or metamaterial. The metamaterial structure contains amalgamation of rectangular and circular shapes to form a design which improvise the patch results to a great extent. The centre of interest in this letter is to…
The neutron absorption section of gadolinium atom is very high, so that the K2GdF5 crystals doped with Tb3+ ions have been studied for neutron dosimetry by the thermoluminescence (TL) method. The K2GdF5 crystals doped 2%, 3% and 5% concentrations of Tb3+ ions were synthesized by solid state reaction method. The TL pro…
Degradation of chitosan in swollen state with hydrogen peroxide solution (5% w/v) by γ-irradiation was investigated. Molecular weight (Mw) of irradiated chitosan was determined by gel permeation chromatography (GPC). Fourier transform infrared (FT-IR) and ultraviolet-visible (UV-vis) spectrawere analyzed to study the…
Binuclear cobalt phthalocyanine was synthesized by microwave method and characterized by infrared spectroscopy, UV-visible spectroscopy and thermogravimetry; its catalytic performance in the oxidative desulfurization of dibenzothiophene (DBT) was investigated. The results showed that the binuclear cobalt phthalocyanin…
Seasonality of freshwater ascomycetes was studied in Nile Delta region from February 2010 to December 2011. One hundred and ten ascomycetes were identified through this investigation. The most common ascomycetes recovered during fluctuation study of Delta region were Zopfiella latipes, Microthelia sp. 1, Helicascus ae…
Multi-wall carbon nanotubes(MWCNT) exhibit extraordinary mechanical and electronicproperties. However, the preparation and processing of MWCNT cpmposites has been limited by their dispersity. The presence of hydroxy groups formed by the surface oxidation of MWCNT increases the dispersion of MWCNT in polytetrafluoroeth…
We prepared aromatic diaminoanthraquinone derivatives a1, b1, a2, b2, a3, and b3 by the reaction of 1,5- and 1,8-dichloroanthraquinone by using aniline, 2-aminobenzothiazole, and 1-aminonaphthalene in order to know the effect on the maximum absorption wavelength due to changes in the aromatic group. The optical proper…
以化学气相渗透(CVI)技术制备的 2D C/ SiC 复合材料为研究对象,探讨复合材料在 700、1000 和 1300°C空气环境中发生不同形式和不同程度氧化损伤后的阻尼行为变化。 采用扫描电子显微镜(SEM)观察和分析复合材料的微结构损伤, 采用动态力学分析仪(DMA)测试复合材料损伤前后的阻尼性能。 结果表明:在700°C和1000°C空气环境中,随着氧化时间的延长,2D C/ SiC 复合材料的阻尼性能先增大后降低;而在 1300°C空气环境中,阻尼性能变化较小,且随氧化时间的延长未表现出明显的规律性。 这是由于 C/ SiC 复合材料的阻尼由炭纤维、热解炭界面和碳化硅基体,以及它们之间的相互作用共同形成。 炭纤维和热解…
In this communication, I present the review on the reported work on gas sensing properties of nanostructured Zinc Oxide (ZnO) thin films and particles. Effect of sintering temperature on structure and granular morphology of nanoparticles is discussed in the context of gas sensing. In case of thin films, effect of 'In'…
In this communication, I present the review on the reported work on colossal electroresistance and resistive switching observed in manganite based heterostructures. Role of inert and active top electrode is discussed in detail. Interface related modifications in resistive switching are explained. Mott transition at in…
Soap is a substance that dissolves in water to remove dirt from surfaces such as skin, textiles and other solids. Soaps are mainly used as surfactants for washing, bathing and cleaning. They are also used in textiles spinning and are important components of lubricants. The present study was carried out to assess the v…
The synthesis and characterization of Al2O3 pillared bentonite have been done and its application as catalyst for esterification reaction were studied. The effect of temperature treatment on the synthesis of Al2O3 pillared bentonite towards its characters were studied by calcinations methods with temperature variation…
