We have studied the chemical bonds in pentacoordinated silicon species by means of ab initio molecular orbital calculations. Characteristics of bonds in these species have been examined by transforming the molecular orbitals into several sets of paired interacting orbitals. One can visualize chemical ...

Polyethylene, one of the simplest polymer structures, has a repeatingmerof two covalently bonded carbon atoms having two hydrogen atoms each. The bonding between chains, however, is weak van der Waals type. Most common polymers are based on carbon, however, silicon-based polymers, known assilico...
Adhesion is a technology for assembling carbon fiber (CF) reinforced polymer (CFRP), enabling them to maintain their lightweight and high-stiffness properties. Despite the importance of adhesion, the lack of a molecular-level understanding of the adhesio
A process for preparing silicon carbide by carbothermal reduction is disclosed. This process involves rapidly heating a particulate reactive mixture of a silica source and a carbon source to form a product which shows improved uniformity of crystal size. The product of this process can be used to...
3.2. Characteristics of the Sol with PQXOH Impregnated Figure 4shows the results of DLS measurements. These measurements were performed to determine the particle size in the silica sol (A) and the effect of the dopant PQXOH on the particle size in the doped sol (B). Measurements were carrie...
