Based on the antimicrobial action of nano-silver, a number of “active” FCMs have been developed that are claimed to extend the shelf-life of food by inhibiting the growth of microorganisms. As commercialization of nano-silver grows, the public and the governments become more concerned about the safety and environmental effects of the widespread use of products containing nano-silver [2]. Severa...
Non-conductive film with Zn nano-particles (Zn-NCF) is an effective solution for fine-pitch Cu-pillar/Sn– Ag bump interconnection in terms of manufacturing process and interfacial reliability. In this study, NCFs with Zn nano-particles of different acidity, viscosity, and curing speed were formulated and diffused Zn contents in the Cu pillar/Sn–Ag bumps were measured after 3D TSV chip-stack bon...
One of the most important goals in the medicine, pharmacology, pharmaceutical, physiological, clinical, biological, medical and medicinal sciences, biochemistry, pharmacogenomics and pharmacoproteomics of anti-cancer Nano drugs such as phosphodiesterase-5 (PDE5) inhibitors and paclitaxel albuminstabilized nanoparticles is the treatment. The present methods and techniques of Nano-structuring ant...
Synthesis and characterization of nano-crystalline silicon grown by atom beam sputtering technique are reported. Rapid thermal annealing of the deposited films is carried out in Ar + 5% H2 atmosphere for 5 min at different temperatures for precipitation of silicon nano-crystals. The samples are characterized for their optical and structural properties using various techniques. Structural studie...
Using two nano-porous pseudo carbon paste electrodes (Nano-PPCPEs) as the working electrodes, a saturated calomel electrode as the reference electrode, and a Pt electrode as the counter electrode to form a four-electrode system, a novel type of glutamate-acetylcholine electrochemical biosensor array was successfully fabricated. It was shown that the biosensor array displayed a high selectivity ...
فرآیند ماشینکاری به روش تخلیه الکتریکی( edm)، یکی از فرآیندهای نوین ماشینکاری است که کاربردهای متنوعی در ساخت و تولید محصولات میکرومتری دارد. رشد و توسعه نانوتکنولوژی و نیاز به بهره گیری از روشهای جدید موجب شده است که جذبه زیادی برای استفاده از فرآیند edm در ساخت و تولید محصولات نانومتری ایجاد شود. فرآیند nano-edm یک فرآیند ماشینکاری حرارتی است که در آن از انرژی حرارتی حاصل از جرقه الکتریکی برا...

We have prepared a series of nano-sized aluminium nitride (nano-AlN)/cycloaliphatic epoxy/trimethacrylate (TMPTMA) systems and investigated their morphology, thermal conductivity, thermal stability and curing behavior. Experimental results show that the thermal conductivity of composites increases with the nano-AlN filler content, the maximum value is up to 0.47 W/(m!K). Incorporation of a smal...
در این مطالعه، فرمولاسیون¬های نانوی نور تخریب¬پذیر و زیست¬سازگار ایمیداکلوپرید و ایندوکساکارب، به واسطه¬ی کپسوله کردن مستقیم هر کدام ازآنها با کوپلیمرهای خطی- دندریتیک پلی¬سیتریک¬اسید-پلی¬اتیلن¬گلیکول-پلی¬سیتریک¬اسید (pca-peg-pca) تهیه شدند. سنتز این نانوآفت¬کش¬ها به دو صورت بدون کاربرد نانوذرات tio2 (nano-ind و nano-imi) و با کاربرد نانوذرات tio2 (nano-ind/tio2 و nano-imi/tio2) انجام شد. فرمول...
