Advanced electrochemical characterization of copper deposition
The electrodeposition of copper metal in a concentrated sulfuric acid solution is reported to occur through a four-step mechanism: (I) the dehydration of Cu2+ (H2O)6, (II) the reduction of Cu2+ to cu+, (III) the dehydration cu+ (H2O)6-x, (IV) the reduction of Cu+ to copper metal. The dehydration …

Chemical vapor deposition of antimicrobial polymer coatings
… surfaces antimicrobial. Initiated chemical vapor deposition (iCVD), a solventless low-temperature process, is used to form thin films of polymers on fragile substrates. To improve research efficiency, a new combinatorial iCVD system was fabricated and used to efficiently determine the deposition …

Initiated chemical vapor deposition of functional polyacrylic thin films
Initiated chemical vapor deposition (iCVD) was explored as a novel method for synthesis of functional polyacrylic thin films. The process introduces a peroxide initiator, which can be decomposed at low temperatures (<200⁰C) and initialize addition reaction of monomer species. The use of low …

Investigation of the role of dietary myo-inositol hexakisphosphate (phytate) on the relative risk of calcium oxalate kidney stone formation in black and white male South African subjects
… to measure the CaOx metastable limit, "C-oxalate deposition kinetics and inhiOition of CaOx crystal aggregation. The results showed that while on their free diets, rural blacks excreted significantly less IPs than urban whites despite their previously reported higher dietary intake of this …

Ocular compatibility of hydrogel contact lenses:deposition and clinical performance
… which over 75% wear hydrogel lenses. Significant deposition occurs in approximately 80% of hydrogel lenses and many contact lens wearers cease wearing lenses due to problems associated with deposition. The contact lens field is not alone in encountering complications associated with interactions …

Polymeric thin films by chemical vapor deposition for the microelectronics industry
… much greater than by CVP. A specially modified deposition system was constructed to study deposition kinetics. A model was developed which allowed quantification of the order of initiation of paraxylylene (PX), which is the initiation system for all the work reported here. This model suggests a …
