In chemistry, deposition is the settling of particles (atoms or molecules) or sediment from a solution, suspension mixture or vapor onto a pre-existing surface. Deposition generally results in growth of new phase and is of fundamental importance in a...

SYNTHESIS OF 4-AMINO DERIVATIVES OF 5,7-DICHLOROKINURENIC ACID THAT LED TO UNEXPECTED PRODUCTS VIA DETOSYLATION. Stephen Craig, Al Nichols, and Nagarajan Vasumathi, Dept. of Physical and Earth Sciences, Jacksonville State Univ., Jacksonville, AL 36265. Starting with ethyl 5,7-dichloro-4-{[(4-methylphenyl)sulfonyl]amino}quinoline-2-carboxylate prepared by a previously reported...

A team of materials researchers at Rice Univ., Houston, have developed what looks to be a relatively simple method of diamond-film deposition. The new method, called halogen-assisted chemical vapor deposition (CVD) appears to be more efficient and less complex than conventional processes....
