University of Southampton Scientists are using a pioneering method of 'caging' and cooling water molecules to study the change in orientation of the magnetic nuclei at the centre of each hydrogen atom - a process which transforms the molecule from one form of water to another. By trapping water molecules in carbon spheres and cooling them, scientists at the universities of Southampton, Nottingham and Columbia University in New York, have been able to follow the change in form (or...

Water Caged In Buckyballs Provides Insight Into Spin Isomers
2014-05-21 03:14:35

By Jason Bardi, American Institute of Physics In a new paper in the Journal of Chemical Physics, produced by AIP Publishing, a research team in the United Kingdom and the United States describes how water molecules "caged" in fullerene spheres ("buckyballs") are providing a deeper insight into spin isomers -- varieties of a molecule that differ in their nuclear spin. The results of this work may one day help enhance the analytical and diagnostic power of nuclear magnetic resonance (NMR)...

Some 14 years ago, a family of biological compounds found in sponges in the South Pacific was shown to have very promising effects in fighting leukemia.  Further studies have been stifled for years however by the scarcity of the substance.But a group of researchers at the Scripps Research Institute has recently discovered a way to circumvent this problem.Using a few basic amino acids, acetylene gas and a tremendous bit of ingenuity, the research team has developed a technique for...

To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. The research results will be published in the March 2009 issue of the journal ACS Nano."Our results allow us to control the chemical and physical properties...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
