Chemistry of the Quantum Kind
Posted by Weizmann Science Writer on October 12, 2012 Today’s post is about some cool chemistry – very cool. About 0.01°Kelvin, as a matter of fact (that is, one hundredth of a degree above absolute zero). Physics experiments conducted at such temperatures are already old hat, but chemistry is another story, altogether. Scientists have been attempting to produce chemical reactions at ultra-low temperatures for…
Not Just the Carbon Cycle
Posted by Weizmann Science Writer on July 24, 2012 You’ve heard of the carbon cycle, maybe even the nitrogen cycle. But have you given much thought lately to the sulfur cycle? New research in last week’s Science suggests that we should be paying a bit more attention to the way this element moves through the atmosphere, biosphere, oceans and land. Over the last 500…
Quasicrystals on Tap
Posted by Weizmann Science Writer on December 12, 2011 If you followed this year’s chemistry Nobel, you know about the quasicrystal design on the ties made for Prof. Dan Schechtman’s 70th birthday. Even the prime minister was seen sporting one last week. But did you know there is also a quasicrystal scarf? While Prof. Schechtman was getting his white tie and tails ready for…
Uncrossing the Wires
Posted by Weizmann Science Writer on August 28, 2011 A recent study by Prof. Ernesto Joselevich and his team, published in Science, features perfectly aligned horizontal arrays of thin, millimeter-long nanowires. We spoke with Joselevich recently to find out why he and others in the field are excited by this advance: WSW: Your lab has produced a fair amount of innovative research in recent…
