Anode materials with high specifi c capacity and rate capability are one of the key components of such batteries. Traditional carbon-based anode materials exhibit acceptable overall performance with respect to the energy/power requirements of existing portable electronic devices, but have a relatively low specifi c capacity, poor Li + insertion/extraction kinetics, and documented safety issues....

Creation of synthetic catalysts with enzyme-like behavior is challenging despite strong interest in such systems. Extraction of tetrachloroaurate into the hydrophilic core of an interfacially cross-linked reverse micelle (ICRM) produced an artificial "metalloenzyme" with highly unusual catalytic properties. The ICRM pulled the substrate toward the catalytic metal, which converted it efficiently...

In advanced very-large-scale integration (VLSI) circuits, the planarity of each metal layer and interlayer dielectric (ILD) is essential to avoid significant yield losses. The primary technique used to attain high levels of planarity is chemical-mechanical polishing (CMP). Several studies of CMP process impact on electrical parameters [1] and planarity [2] are available. In order to reduce the ...

A new simple and reliable method for rapid and selective extraction and determination of trace levels of Zn(II) ion is developed. Zn(II) ions are adsorbed quantitatively during passage of aqueous samples through PET-AA/AAm nano fiber modified. Almost all matrix elements were found to pass through the nano fiber to drain. Modified Poly (ethylene terephthalate)-grafted-Acrylic acid/Acryl amide Na...
