Article Abstract:
The ab initio molecular orbital method was used in studying the oxidation of dimethylamine borane (DMAB) as a reductant for an electroless deposition process. Reactions through three-coordinate borane molecules or through five-coordinate ones by primary addition of OH- were investigated. Electroless deposition is used in creating metal thin films by reducing metal ions in electrolytes. Results indicated that the five-coordinate compounds are transition states while the five-coordinate molecules have bipyramidal structures.

Article Abstract:
A study was conducted, using electrochemical analyses and in situ attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), to understand the deposition mechanism of Ni on Si(100) in aqueous alkaline solution. The result from the study reveals that the deposition reaction is initiated by the formation of suboxide-covered surface, as the open circuit potential (OCP) shifts negatively.

Article Abstract:
The formation of organosilane monolayers having different operational clusters on silicon oxide surfaces for fabricating on-chip bio-sensing instruments is studied. It was established that the pH sensitivity of these surfaces was significantly influenced by the difference of the operational clusters.
