The past October marked an exciting time for those in the field of isotopic science. Two brand new approaches to isolate and enrich light elements have been reported. Although a variety of elements ...

An international team of researchers have found a better way to separate two rare and important gases—xenon and krypton—that ...

On November 27, the New Energy and Industrial Technology Development Organization (NEDO) and the National Institute of Advanced Industrial Science and Technology (AIST) announced that, as a part of ...

CROSS-LINKED dextran (‘Sephadex’) has been shown to possess properties of a molecular sieve 1. The size limits for effective molecular sieving depend on the degree of cross-linking. Molecules or ions ...

The effects of global warming are becoming more serious, and there is a strong demand for technological advances to reduce carbon dioxide emissions. Hydrogen is an ideal clean energy which produces ...

The outcome of this project will be large-scale energy saving in separation processes of chemical industry. One of the two targets of this project is to develop advanced molecular-selective membrane ...

Deuterium is the heavy twin brother of hydrogen; however, it is more than 20 times rarer than identical twins. It accounts for only 0.015 percent of natural hydrogen and is twice as heavy as the light ...

(Nanowerk Spotlight) The petrochemical industry relies on separating chemicals that differ by just fractions of a nanometer in size. Methanol must be purified from similarly-sized molecules in the ...

A simple method for sieving benthic macrofauna samples aboard ship is described. The method is based on an inexpensive set of nested sieves that efficiently screens macrobenthic species from bottom ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 87, No. 23 (Dec., 1990), pp. 9193-9196 (4 pages) Multisurface pattern separation is a mathematical method for ...
