Rice, UIUC researchers find way to separate metallic, non-metallic nanotubes

Researchers at Rice University and the University of Illinois at Urbana-Champaign have discovered the first method to chemically select and separate carbon nanotubes based on their electronic structure. The new process, described in the Sept. 12 issue of Science magazine, represents a fundamental shift in the way scientists think about the chemistry of carbon nanotubes.

“Other than low-cost mass prod

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are using a very small and light ion, the electron, to study the structure and dynamics of ionic liquids and how those properties influence chemical reactivity.

Ionic liquids are made of positive and negative ions that pack so poorly together that they are liquids near room temperature. They offer extremely low volatility, non-flammability, new reactivity patterns, and the formation of separate phases that all

Scientists at the U.S Department of Energy’s Brookhaven National Laboratory are exploring the use of bacteria to increase the recovery of methane, a clean natural gas, from coal beds, and to decontaminate water produced during the methane-recovery process.

Methane gas, which burns without releasing sulfur contaminants, is becoming increasingly important as a natural gas fuel in the U.S. But the process of recovering methane, which is often trapped within porous, unrecovered or waste co

Modern radiometric dating of the Siloam Tunnel in Jerusalem shows that it was excavated about 700 years before the Common Era, and can thus be safely attributed to the Judean King Hezekiah. This is the first time that a structure mentioned in the Bible (Kings II 20:20; Chronicles II 32:3, 4) has been radiometrically dated.

A report on the study of the Siloam Tunnel will be published on Sept. 11 in the scientific journal Nature. The research was conducted by Dr. Amos Frumkin of the Geograp

Dryness in the mouth is not an agreeable sensation and much less so if the condition becomes an illness. Effectively, there are illnesses related to lack of saliva, as is the case of the sicca-sicca disease and the Goujerot-Sjögren syndrome.

The research regarding these uncommon illnesses began to be important in 1976 when new functions of the molecule ATP (adenine triphosphate) were discovered. In that year it was found that the ATP molecule and its derivative controlled a number of biologi

In the VIIth International Conference on Agri-Food Antibodies that is going to be held in September in Uppsala (Sweden), AZTI is going to present immnunosensors to detect pesticides.

AZTI has a great deal of experience in this area, since it has worked several years in projects related to research and development of biosensors adapted to the needs of the food industry. Biosensors or rapid monitoring tools are great potentials for the food industry, because in contrast to conventional analyti
