Sulfur dioxide is one of the major components of acid rain emitted into the atmosphere resulting from fuel combustion and ore roasting process. The need for sulfur dioxide removal has been demonstrated, but the high cost of existing processes has prevented the wide application of sulfur dioxide remo.....

The present invention relates to the construction of hyperbranched polytriazoles and linear and hyperbranched poly(aroyltriazole)s by Huisgen 1,3-dipolar polycycloaddition. The polymers were prepared by A2 + B3 methodology to avoid self-polymerization during monomer preparation and storage. A new cl.....

A method for the fine-pitch stencil mask design for stencil printing bumping technology for eutectic Sn/Pb and lead-free solder material is described. In the method, a reflowing enhancement layer is introduced to improve the solder quality and reduce the pitch of solder bumps. The method of forming .....

Thin film transistors (TFTs) fabricated on polycrystalline silicon (polysilicon) have gained much attention in flat panel displays such as active matrix liquid crystal displays (LCDs) and in static random access memory (SRAM) units. In comparison with thick film devices TFT devices made with a thin .....

Almost all soil slopes on land are initially unsaturated in nature. In order to determine the factor of safety of unsaturated slopes accurately, it is essential to calculate transient seepage and hence pore water pressures in the soil. To do so, one has to measure the so-called soil-water characteri.....
