Electrospinning utilizes an electrical force to generate a fine, charged jet from the surface of a viscous liquid. This jet moves straight towards a grounded collector for a certain distance, then bends into spiral coils; finally, the jet solidifies and collects as nonwoven cloth. The onset and development of the electrical bending instability were investigated. Under certain conditions, high applied voltage prohibited the onset of bending and a straight jet reached the collector. Submicron fibers were produced by collecting a straight jet on a moving collector. The diameter,...

This book contains material from the lecture courses conducted at the Theoretical Advanced Study Institute (TASI, Colorado, USA) on high energy physics and cosmology in 2008. Three series of lectures are presented in parallel in the areas of Large Hadron Collider (LHC) phenomenology and experimentation; advanced theoretical topics beyond the standard model; and neutrino oscillation, astroparticle physics and cosmology. The phenomenology lectures cover a broad spectrum of standard research techniques used to interpret present-day and LHC data. The new physics lectures focus on modern...

This book presents the techniques and solutions for enhancing energy efficiency of future mobile networks, and consists of three major parts. The first part presents a general description of mobile network evolution in terms of both capacity and energy efficiency. The second part discusses the advanced techniques to green mobile networks. The third part discusses the solutions that enhance mobile network energy efficiency as well as provides future directions. Whilst the reader is expected to have basic knowledge of wireless communications, the authors present a brief introduction of the...
