Transportation: maglev rail, subways

Article Abstract:

Asia's Pacific Rim extends over more than 60 degrees of latitude and 45 degrees of longitude, making it a principal market for air, land and water transportation. The first bullet train debuted in Japan in 1964, and while the current speed record is held by France's Train a Grande Vitesse (TGV) at 515.3 kilometers per hour (kph), Japan Railways hopes to use magnetic levitation (maglev) to approach that speed with its Shinkansen train running between Tokyo and Osaka. South Korea and Taiwan are also preparing bullet train projects. Japan, South Korea, Singapore and Hong Kong have modern subway systems, each of which is described briefly. Japan's four international air carriers and four domestic airlines are led by All Nippon Airways Co and Japan Airlines Co; air transportation in Hong Kong and Korea is also described.

Nanoporous carbon membrane transportation measured and modeled

Article Abstract:

Researchers at the University of Delaware's Chemical Engineering Dept have successfuly measured and modeled the single component permeances of six gases on three different support nanoporous carbon membranes. The finding relates to a study on the transport behavior of a set of small molecules in a thin layer of a nanoporous carbon molecular sieve derived from polyfurfuryl alcohol, that was prepared on a porous stainless steel structure. The researchers say that experimental results will elucidate the underlying mechanism by which shape-selective transport occurs in membranes and by which small molecules are separated.

Membrane speeds water refrigeration

Article Abstract:

Smart Chemical Co. has developed a zeolite refrigerator which uses water as the working fluid. A DTI SMART Award assisted the company in building a demonstration twin-bed zeolite refrigeration system which uses stainless steel vessles and 80W electric heaters to regenerate the membranes. The company now plans to develop inexpensive and highly efficient refrigeration systems for cooling to five deg C.
