Triple Point » News http://pontotriplo.org/triplepoint A selection of posts from Ponto Triplo - a Portuguese blog with links to the best chemistry sites, news and events Sun, 19 Apr 2009 23:15:30 +0000 en hourly 1 http://wordpress.org/?v=3.3.2 Prizes and Something More http://pontotriplo.org/triplepoint/2005/11/prizes_and_some.html http://pontotriplo.org/triplepoint/2005/11/prizes_and_some.html#comments Mon, 21 Nov 2005 23:14:00 +0000 Jorge Goncalves http://pontotriplo.org/triplepoint/?p=132 ]]> It is not new that the 2005 Nobel Prize in Chemistry was awarded jointly to Yves Chauvin, Robert H. Grubbs and Richard R. Schrock “for the development of the metathesis method in organic synthesis”. Recently, in recognition of their achievement, American Chemical Society (ACS) decided to provide free access to 101 articles published in ACS journals over the past 10 years by chemistry’s newest Nobel Laureates, namely in Journal of the American Chemical Society, Organometallics, The Journal of Organic Chemistry and Organic Letters. For the papers published prior to 1996 the access to the abstract is provided.

(Almost) Related: The 2005 Ig Nobel Prizes winners are already known. One should remember that “every Ig Nobel Prize winner has done something that first makes people laugh then makes them think”. The Ig Nobel Prize in Chemistry is a confirmation of this statement. The proud winners were Edward Cussler of the University of Minnesota and Brian Gettelfinger of the University of Minnesota and the University of Wisconsin, “for conducting a careful experiment to settle the longstanding scientific question: can people swim faster in syrup or in water?” For the records, the article, named “Will Humans Swim Faster or Slower in Syrup?”, has been published on the American Institute of Chemical Engineers Journal.

Previously, in 2000, the mass of a cluster of gold atoms, near one attogram (10-18 g) was already measured. The next goal, a gigantic step, is to develop devices capable of weighing masses on the yoctogram (10-24 g) scale, meaning measuring the mass of a single hydrogen atom. The article is worth reading as is this one, published on PhysOrg.
