thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
PURPOSE Rapid development of nanotechnology has recently brought significant attention to the extraordinary biological features of nanomaterials. The objective of the present investigation was to evaluate morphological characteristics of the assembles of gold and platinum nanoparticles (nano-Au and nano-Pt respectively), with Salmonella Enteritidis (Gram-negative) and Listeria monocytogenes (Gr...
Environmental, health, and safety (EHS) concerns are receiving considerable attention in nanoscience and nanotechnology (nano) research and development (R&D). Policymakers and others have urged that research on nano's EHS implications be developed alongside scientific research in the nano domain rather than subsequent to applications. This concurrent perspective suggests the importance of early...
روش تولید بیودیزل ازروغن پسماند، استفاده از روش دو مرحله ای استریفیکاسیون اسیدی وترانس استریفیکاسیون است.در این تحقیق به منظور کاهش هزینه های تولید و کاهش مقدار کاتالیست و افزایش راندمان بیو دیزل، از سنتز نانو کاتالیستهای معدنی در دسترس نظیر اکسیدهای فلزات قلیایی خاکی (اکسید کلسیم و اکسید باریم) سنتز شده در فرآیند مورد استفاده قرار گرفته است. در نهایت با انجام آزمایشات ،بهینه ترین بازده برای تو...
Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...
the level of dental and oral hygiene on elementary school age children is very low, so it can be increasing the incidence of dental and oral diseases which caused by various microorganisms. moutwash can keep dental and oral hygiene, but many commercial mouthwash is still used alcohol as their ingredients, which can be giving side effects, therefore, we still needed used alternative mouthwash, w...
objective: curcumin is extracted from curcuma longa and regulates the intracellular signal pathways which control the growth of cancerous cell, inflammation, invasion and apoptosis. curcumin molecules have special intrinsic features that can target the intracellular enzymes, genome (dna) and messengers (rna). a wide range of studies have been conducted on the physicochemical traits and pharmaco...
