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...

About thirty years ago, the problem of the localization of rapid plastic deformation of a number of polycrystalline metals into adiabatic shear bands began to receive considerable attention, mainly due to its connection with military applications, such as armor penetration. However, the phenomenon had been observed much earlier in metal machinin...
