Aluminium base alloy (Al-Cu-Si) was reinforced with silicon carbide (SiC) particles, in various percentage compositions from 0-20 wt%. Silicon carbide particle size of 20µm was selected. The molten slurry of SiC reinforced base aluminium metal was casted through green and dry sand casting methods and solidification process was carried out under ambient conditions. A selected population...

In this study, some metals (aluminium, chromium, copper, iron, manganese, lead, zinc and vanadium) and metalloid (silicon) were determined in water, sediment and some tissues of fish Cyprinus carpio from Mogan Lake. Fish samples were caught in March 2007. As a result of the examination of metals in the water aluminium has the lowest and silicon has the highest concentration. In sediment samples...

In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...

Porous silicon (PS) samples are obtained by electrochemical anodization of Si wafers in HF+DMF solution. The hydrogen complex components are formed on the inner surface walls of porous silicon. In this work the depth profile of porous silicon is estimated by measurement of hydrogen content in the depth of the sample. Since the well-known ion beam analysis simulation programs are inappropriate f...

In this paper, radiation effects in protection layers of logical cell of the digital gate in the FPGA for electron and proton rays was simulated Using the FLUKA Code. by using of the Monte Carlo simulation, the electron and proton transport into the logical cell of the digital gate in the FPGA will be studied. In this simulation, the maximum energy of the electrons and protons at the entrance o...
