Air wins a new role as a refrigerant

Article Abstract:

Air Products and Chemicals Inc is one of the recipients of the 1999 Kirkpatrick Chemical Engineering Achievement Awards. The Allentown, PA- based company is recognized for developing a gas-phase system for low temperature refrigeration using air and other inert gases as its working fluid. Named Closed Cycle Air Refrigeration system, the process employs a reverse Brayton cycle, which was proven efficient for refrigeration at low temperatures.

Ternary hydride releases H2 quickly at low temperatures

Article Abstract:

Researchers from Ford Motor Co. and the University of California, Los Angeles were able to develop a hydrogen compound that could be used as an automotive hydrogen-storage material. The compound is a mix of lithium amide, lithium borohydride, and magnesium hydride in a 2:1:1 ratio which provides faster kinetics, lower desorption temperature and has no dangerous byproducts.
