The bidirectional switch (Bi-Sw) is a power device widely used by power conversion systems. This paper presents a novel modular design of a Bi-Sw with the purpose of providing to beginner researchers the key issues to design a power converter. The Bi-Sw has been designed in modular form using the SiC-MOSFET device. The Bi-Sw uses the advantages of SiC-MOSFET to operate at high switching

Boron carbide is an ultrahard ceramic material that has many useful appliions, most notably as body armor. This is due to the material’s high hardness (>30 GPa), coupled with its low density (2.52 g/cm 3) [1,2,3].The boron carbide (B 4 C) structure is predominantly made up of (B 11 C) icosahedra, with the carbon atom residing in a polar site and the CBC chain connecting the icosahedra
For the synthesis of Ag-based alysts, Ag foils (99.97% purity and 125 μm thickness) were mechanically polished with silicon carbide paper (400 grit) and subsequently rinsed in deionized water and dried with argon (Ar).

A silicon carbide furnace will do very well for the manufacture of the carbides, since the zirconium carbide remains in the core of the charge and the silicon carbide forms in the cooler outer zone. Thomson, ~ and more recently Kinzie, 1
2020/8/17· Silicon carbide grit blast media is brittle, sharp, and suitable for grinding metals and low-tensile strength, non-metallic materials. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing.
