Ceramic/metal Nanocomposites by Lyophilization: Processing and Hrtem Study
This work describes a wet-processing route based on spray-freezing and subsequent lyophilization designed to obtain nanostructured ceramic/metal powders. Starting from the ceramic powder and the corresponding metal salt, a water-based suspension is sprayed on liquid nitrogen. The frozen powders are subsequently freeze-dried, calcined and reduced. The material was analyzed using X-ray diffractio...
متن کاملQUANTITATIVE STUDY OF Au CATALYTIC NANOPARTICLES BY STEM AND HRTEM
The highly dispersed metal (e.g. Au) nanoparticles have exhibited exceptional catalytic activity for several reactions, including CO oxidation. Their high catalytic activity has been attributed to nanoparticles nano-structural effects (including cluster thickness, shape, chemical information, and number of atoms of the cluster). The three dimensional exact structure and chemical bonding state o...
متن کاملStudy on Mechanical and microcrystalline on hybrid nanocomposites by WAXS
The aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. A series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of TS viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. The microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...
متن کاملa comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation
هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولClay-Epoxy Nanocomposites: Processing and Properties
The work described in this paper is focused on evaluating the effect of the processing method and nanoclay (montmorillonite) content on the tensile, compressive, and impact properties of clay-epoxy nanocomposites. Nanocomposites are synthesized by two methods: mechanical mixing and shear mixing. Both these methods are capable of producing bulk quantities of clay-epoxy nanocomposites. X-ray diff...
