The total oxidation of toluene at a wide temperature range (200–500 oC) over micro/mesoporous platinated catalysts has been investigated about activity, selectivity to CO2 and CO, catalyst's stability versus coke deposition and reaction kinetics. Kinetic of toluene oxidation was measured under various oxygen and toluene pressures and als...

abstract microbial contaminants transport to groundwater is a serious environmental problem that can result in large outbreaks of waterborne diseases. some of bacteria can travel from vadose zone and cause contamination of groundwater resources. thus, an accurate prediction of transport and fate of pathogenic microorganisms in unsaturated soil is needed to protect groundwater resources. the mai...

The formation of Au microbump arrays for flip-chip bonding was investigated using an electroless Au plating bath. Generally, electroless Au deposition gives a low deposition rate, preventing the fabrication of Au bumps with heights of more than 5 μm. To overcome this problem, we developed a new electroless Au deposition process that employs a non-cyanide bath. This process delivers a high depos...

Secondary-treated municipal wastewater (MWW) is a promising alternative to freshwater as power plant cooling system makeup water, especially in arid regions. A prominent challenge for the successful use of MWW for cooling is potentially severe mineral deposition (scaling) on pipe surfaces. In this study, theoretical, laboratory, and field work was conducted to evaluate the mineral deposition po...

Vapor-phase synthesis techniques of polymeric nanostructures offer unique advantages over conventional, solution-based techniques because of their solventless nature. In this work, we report the fabrication of coaxial polymer nanotubes using two different chemical vapor deposition methods. The fabrication process involves the deposition of an outer layer of the conductive polyaniline (PANI) by ...

In the second half of the 20th century, scientists have been attracted to the design of thin solid films at the molecular level because of their potential for applications in the fields of biology and medicine. Two techniques dominated research in this area: Langmuir–Blodgett deposition and self-assembled monolayers (SAMs). Both Langmuir–Blodgett deposition, invented by Langmuir and Blodgett, a...

Organic solid/solid wetting deposition (OSWD) is an easy, low cost method to prepare epitaxial monolayers of organic semiconductors under ambient conditions. This chapter describes various approaches to induce complexity into highly ordered monolayers with Scanning Tunnelling Microscopy (STM): nanomanipulated self-assembly aiming towards molecular data storage, locally guided selfassembly to ac...
