TOOLS & TECHNIQUES UPDATE

Working in the cold The fourth edition of Experimental Techniques in LowTemperature Physics by Guy White and Philip Meeson has taken into account all the changes in the past 20 years in cryogenic technology. It aims to provide a resource enabling physicists, materials scientists, engineers, physical chemists, and biologists to carry out low temperature investigations. It is targeted at both graduate students and professionals, combining information on basic physics, techniques, and commercially available products. This edition also includes comprehensive tables of the physical properties of metals, polymers, and ceramics.

Pressure controller MKS Instruments, Inc. is producing a new digital pressure controller for use in semiconductor processing applications. The MKS Type PC10A is a self-contained system that uses the DeviceNet™ communications protocol. Its applications include chemical vapor deposition source gas delivery, wafer cooling, and loadlock pressure control. The device consists of a MKS Baratron® capacitance manometer, a proportioning

First of four The Handbook of Polymer Blends and Composites, Volume One, edited by Anand K. Kulshreshtha and Cornelia Vasile, is the first in a series of four volumes. The volume includes both theoretical and practical investigations on the fundamental nature of polymer composites and the thermodynamics of mixing multicomponent systems. The book is aimed at students, academic researchers, and workers in industry. Later volumes will cover polymer blends.
