عملیات دوگانه مهندسی سطح (نیتروژن دهی پلاسمایی _ رسوب فیزیکی بخار) نسل نوینی را تشکیل می دهند که کارایی آنها از دو دیدگاه در فرایندهای آهنگری مطرح است. دیدگاه اول استفاده از این پوشش ها با هدف افزایش عمر قالب های آهنگری است و دیدگاه دوم مربوط به قابلیت جایگزینی این پوشش ها با روانکار است تا از اثرات مخرب زیست محیطی روانکارها جلوگیری شود. هدف از این پژوهش بررسی کارایی نسل نوین پوشش های با عملیات...
In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This analyzed use a Spectrophotometry spectral region 200-800 nm. The absorption enhances when added TiN NPs polymeric matrix which may be for various applications such as optoelectronic detector. optical ener...
A hydrothermal method based on the use of hydrogen peroxide is described to grow a homogeneous layer of tungsten oxide (WO3) on a platinum (Pt) film supported on a silicon wafer. WO3 growth is highly selective for Pt when present on silicon in a patterned arrangement, demonstrating that Pt catalyzes decomposition of the WO3 precursor in solution. The obtained Pt/WO3 interface yields high photoc...
The selection of an appropriate substrate is an important initial step for many studies of electrochemically active materials. In order to help researchers with the substrate selection process, we employ a consistent experimental methodology to evaluate the electrochemical reactivity and stability of seven potential substrate materials for electrocatalyst and photoelectrode evaluation. Using cy...
We demonstrate a novel optoelectronic tweezer using light induced dielectrophoresis mechanism to optically trap and transport micro particles with optical power in the μW range. This device consists of two pattern-less surfaces: a bottom glass substrate coated with photoconductive material and a top transparent indium-tin-oxide (ITO) glass. To achieve optical trapping, we sandwich the liquid-im...
A multisensor based on tin and tin–titanium oxides has been utilised to detect pollutant gases (NO2, CO, toluene and octane). The sensitive layers are deposited by r.f. reactive sputtering. Some tin oxide sensors are doped with Pt. Measurements are carried out with single gases and gas mixtures (two and three gases) in dry air at 250 ◦C. An exhaustive analysis of several networks and feature ex...

A lab-on-a-disc (LOAD) is a centrifugal microfluidic set-up based on centrifugal force without using micro-pumps to drive reagents and cells to various chambers through channels and valves for reactions. A LOAD coated with conductive transparent indium tin oxide (ITO) for thermal control was developed to screen allergy-blocking agents. When the acridine orange (AO)-loaded KU-812 human basophili...
