Resonance Raman intensity analysis of ClNO2 dissolved in methanol
(2013)Halogens such as chlorine are converted from halides, including ClNO 2, to reactive radicals by UV solar radiation. These radicals can affect ozone production and destruction in the stratosphere. Recently, it became clear ...

Synthesis of Tin nitride Sn xN y nanowires by chemical vapour deposition
(2009)Tin nitride (Sn xN y) nanowires have been grown for the first time by chemical vapour deposition on n-type Si(111) and in particular by nitridation of Sn containing NH 4Cl at 450 °C under a steady flow of NH 3. The Sn xN ...

Topic 1: Support tools and environments
(2008)The spread of systems that provide parallelism either "in-the- large" (grid infrastr-uctures, clusters) or "in-the-small" (multi -core chips), creates new opportunities for exploiting parallelism in a wider spectrum of ...
