Porous silicon obtained on n-type silicon by photoelectrochemical etching in HF, is formed of a macroporous silicon layer beneath a nanoporous silicon layer. Microstructural investigations and chemical analysis at the aiomic level of the nanoporous silicon film (obtained from a highly doped (Ill) oriented Si substrate) have been done by high resolution transmission electron microscopy (HRTEM) a...

introduction: knee orthosis is used in different cases and can be seen pistoning movement in all orthosis. the purpose of this study was to evaluate the effects of increasing mass knee brace and two kinds of silicon and polyethylene (pe) pad on pistoning movement during walking, on health subject. material and methods: a total of 20 healthy volunteers, including 10 men and 10 women, with an ave...

A metallic coupler is proposed to interface a silicon on insulator (SOI) waveguide with a narrow hybrid plasmonic waveguide (200× 200 nm). The device operation is investigated and optimized to attain the best tradeoff between the mode confinement and the propagation loss. Calculations reveal that a high confinement and low loss of the energy is achieved from a silicon slab waveguide into the di...

Microwave heating is applied for processing different silicon raw materials, based on the size-, shapeand composition-dependent absorption of radiation of 2.45 and 916 MHz frequency by silicon. In model experiments directed towards the improvement of melting technology, Si-fines and chunks of bulk Silicon from Electronic Grade (EG)and Solar Grade (SG)-silicon production are used as raw material...

Silicon thin layers are deposited on glass substrates with the thickness of 103 nm, 147 nm and 197 nm. The layers are produced with electron gun evaporation method under ultra-high vacuum condition. The optical Reectance and the Transmittance of produced layers were measured by using spectrophotometer. The optical functions such as, real and imaginary part of refractive index, real and imaginar...

In animals, silicon is an abundant and differentially distributed trace element that is believed to play important biological functions. One would thus expect silicon concentrations in body fluids to be regulated by silicon transporters at the surface of many cell types. Curiously, however, and even though they exist in plants and algae, no such transporters have been identified to date in vert...

in this study the effect of different concentrations of silicon( 0, 2 , 4 and 6 mm, on expression of some genes involved in resistance and activity of several antioxidan enzymes was investigated: the plants was treated in flowering stage via soil solution. the treated plants were inoculated with 106 spore suspended in 1 ml by injection into the lower part of the spikelets and then were harveste...

An experiment was conducted with rats to determine whether silicon deprivation affects the inflammatory response to the injection of type II collagen, and to compare the effectiveness of the organic complex arginine silicate inositol (ASI) with inorganic silicon (NaSiO(3)) in mitigating any observed change in response. Dark Agouti rats were fed a ground corn-casein-safflower-based diet containi...

this study was conducted to investigate the effects of planting date, foliar application of benomyl fungicide and potassium silicate in improving the quality of soybean (cv. williams) seed in gorgan during 2011 and 2012. in the first year (2011), the experimental treatments were including planting dates (april 20, may 13, june 3, june 29 and july 22) and foliar application of benomyl fungicide ...
