Shape memory effects were studied in a NiTi / Kapton composite produced by deposition of thin layer on substrate electronic beam evaporation. It was shown that after preliminary deformation bending at room temperature, the demonstrated strain recovery heating. An increase increased recoverable maximum value which 2.1 %. The two-way shape effect not observed due to small thickness did exceed 300...
Rice is only second to wheat as a major food for Iranians. It has to be dried for processing and/or storing due to excessive moisture content after harvesting. In most parts of Iran, rice is sun-dried by spreading it on the ground under solar radiation which leads to excessive losses such as attacking birds and rodents, grain contamination, wind and rainfall hazards, as well as thermal and mois...
introduction evaporation is a phenomenon of hidrological cycle that is particularly important in studies of water. much of the annual rainfall in arid and semi-arid weather characteristics that iran immediately returns to the atmosphere. so it will be important to estimate and predict the amount of evaporated to estimate of water. dez basin in south-west iran, where the country's main cent...
VO2 (M) STF through reduction of V2O5 STF was prepared. The results illustrate that V2O5 STF can be successfully obtained by oblique angle thermal evaporation technique. After annealing at 550 °C/3 min, the V2O5 STF deposited at 85° can be easily transformed into VO2 STF with slanted columnar structure and superior thermochromic properties. After deposition SiO2 antireflective layer, Tlum of VO...
Indium-tin-oxide (ITO) nanowhiskers with attractive electrical and anti-reflection properties were prepared by the glancing-angle electron-beam evaporation technique. Structural and crystalline properties of such nanostructures were examined by scanning transmission electron microscopy and X-ray diffraction. Their frequency-dependent complex conductivities, refractive indices and absorption coe...

We report on the fabrication of an enhancement mode p-GaN/AlN/GaN high electron mobility transistor with selective area sublimation under vacuum p-GaN cap layer. The GaN evaporation selectivity is demonstrated thin 2 nm AlN barrier Furthermore, regrowth AlGaN a major key to increase maximum drain current in transistors and enables co-integration depletion devices.
As silicon photovoltaics evolve towards thin-wafer technologies, efficient optical absorption for the near-infrared wavelengths has become particularly challenging. In this work, we present a solution that employs combined micro- and nano-scale surface textures to increase light harvesting in the near-infrared for crystalline silicon photovoltaics, and discuss the associated antireflection and ...
Evaporation is one of the most important components of hydrologic cycle.Accurate estimation of this parameter is used for studies such as water balance,irrigation system design, and water resource management. In order to estimate theevaporation, direct measurement methods or physical and empirical models can beused. Using direct methods require installing meteorological stations andinstruments ...
