Researchers measured oxygen content by measuring the intensity of glow when ultraviolent light and change in electrical conductivity of the tubes exposed. Existing technologies demonstrated sensitivity to oxygen concentrations as low as 5 % with the team calculating that they indicate a value of only 0.4 %, and they were not by other atmospheric gases, such as carbon dioxide and nitrogen. The second paper by Shade by Shade and Pitt chemistry students Douglas Kauffman and Hyounsoo Uh.

Described regards the nanocapsules in Advanced Materials, existing technologies typically polymers which are permeable, have the potential and to leaks to leaks, says Star. In addition, each capsule must be adapted to its particular cargo, he said. The Pitt version employs graphite carbon shells bonded with glutaraldehyde – a common biological adhesive – creating a hollow storage space. More importantly, the graphite shells are chemically inactive and are thus compatible with any cargo substance without costly and time-consuming chemical preparation, Stern said.Social and cultural of genetic, biological, behavioral and socio-cultural basis of the normal behavior, and the causes and consequences of on neuropsychiatric diseases.. He co-authors include Dr. Samuel McCann of from Louisiana State University.
