New, Environmentally Friendly Technique For Separating Liquids Invented At UNC-CH
...Chapel Hill and colleagues. "Liquid-liquid separations are an important process in manymanufacturing industries -- pharmaceuticals, textiles, fine chemicals andnatural products such as taxol, an extract from the yew tree that helps fightcancer," said Dr. Joseph M.

Heithoff, USA (California): While pursuing his Ph.D. at the University of California-Santa Barbara, Heithoff identified a "master switch" that allows bacteria to orchestrate the infe...Synthetic clay could assist radioactive waste cleanup
... said Thomas Chapman, manager of NSF's program for separations and purification processes, which funded the research. "With more development, the swelling micas should prove useful in both waste remediation and metals recovery." The swelling mica tested by Komarneni's team, known as Na4, is one of a grou...A genetic basis for behavior in infancy

Three basic, coherently organized patterns of infant behavior after reunion with the parent (secure, insecure-avoidant, insecure-resistant) have been regarded as adaptations to the experienced differences in care giving.

...ion as a separation technique? "Over 90 percent of separations in the industry are done by distillation," or selectively boiling off compounds, said Yang. "That's very energy-intensive. Adsorption isn't. It can also help with boiling points that are too close." Thus the focus of Yang's research team is developin...Pacific Northwest chemist wins national award for studies of biological systems

His separations are based on what is called capillary liquid chromatography, tiny tubes packed with chemically sensitive "beads" that tease apart mixtures according to size, electrical charge and other molecular properties.
