Research performed in Guy Bertrand's lab offers vast family of new catalysts for use in drug discovery, biotechnology Chemists at the University of California, Riverside have accomplished in the lab what until now was considered impossible: transform a family of compounds which are acids into bases. As our chemistry lab sessions have taught us, acids are substances that taste sour and react with metals and bases (bases are the chemical opposite of acids). For example, compounds of the element...

Guy Bertrand's lab shows metal-free 'abnormal N-heterocyclic carbenes' are stable, allowing their use in numerous catalytic chemical reactions Researchers at the University of California, Riverside have successfully created in the laboratory a class of carbenes, highly reactive molecules, used to make catalysts "“ substances that facilitate chemical reactions. Until now, chemists believed these carbenes, called "abnormal N-heterocyclic carbenes" or aNHCs, were impossible to make....

RIVERSIDE, Calif. "“ Aug. 18, 2005 "“ Chemists at the University of California, Riverside have synthesized a new class of carbenes "“ molecules that have unusual carbon atoms "“ that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs. Called cyclic alkyl amino carbenes or CAACs, the molecules attach themselves to metals, such as palladium, to form highly efficient catalysts that allow...

Word of the Day
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
