Lithium is the lightest metal (6.94 g/mole, specific gravity=0.53 g/cm3) and is highly electropositive (-3.05 V versus standard hydrogen electrode)I. Hence lithium-ion cells have higher specific energy (Wh/kg), higher volumetric energy density (Wh/l), higher specific power (W/kg) and higher volumetric power density (W/l) than other battery chemi...

A PC sold in 2010 had billions of transistors with 32 nm gate-length. In a year, that dimension will shrink to 22 nm. Light is essential to fabrication and quality control of such small semiconductor devices.Integrated circuits are manufactured by repeatedly depositing a film of material and etching a pattern in the deposited film. The pattern i...

In recent years, the structure of complex networks has becomeobject of intense study by scientists from various disciplines;see e.g. [1], [2] and [3], or the book-form paper collection[4]. One often studied mechanism of growth and evolution insuch networks, e.g. social networks, is preferential attachment[2]. In communications network engineerin...
