Esmalla and published by . This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoporous gold film (NPGF) exhibits extraordinary physical and chemical properties different from the bulk material. NPGF also shows an enhancement in its performance properties and high catalytic. This behavior can be attributed to the high surface-to-volume ratio, high surface energy and easy electron transfer. Indeed, there is a need to modify the gold quartz crystal from bulk into nanoporous gold film. A quartz crystal microbalance with nanoporous gold electrodes was fabricated by electrooxidation and consequent reduction reaction with glucose. SEM and AFM micrograph revealed a nanopore diameter ranges from 69 to 72nm, with an average depth of roughness of 6 nm. Cyclic voltammetry was also conducted on the modified gold quartz crystal. The peak was assumed to be adsorption of OHads from H2O or OH at the gold adatom sites. The modified gold quartz crystal gave a stable response (RSD = 9.40 x 10-50/0, n=3), exhibited good reversibility and repeatability (RSD = 0.125%, n=3), good reproducibility (RSD = 0.985%) and fast response time (tr=2 to 3 minutes). The surface modification of gold quartz crystal also rendered its amplification of frequency shift, enhancement of sensitivity and high linearity.

Book excerpt: The impending crisis posed by water stress and poor sanitation represents one of greatest human challenges for the 21st century, and membrane technology has emerged as a serious contender to confront the crisis. Yet, whilst there are countless texts on wastewater treatment and on membrane technologies, none address the boron problem and separation processes for boron elimination. Boron Separation Processes fills this gap and provides a unique and single source that highlights the growing and competitive importance of these processes. For the first time, the reader is able to see in one reference work the state-of-the-art research in this rapidly growing field. The book focuses on four main areas: Effect of boron on humans and plants Separation of boron by ion exchange and adsorption processes Separation of boron by membrane processes Simulation and optimization studies for boron separation Provides in one source a state-of-the-art overview of this compelling area Reviews the environmental impact of boron before introducing emerging boron separation processes Includes simulation and optimization studies for boron separation processes Describes boron separation processes applicable to specific sources, such as seawater, geothermal water and wastewater
