The spectacular reaction of alkali metals with water was poorly understood despite being a staple of chemistry classes The neurologist and celebrated author Oliver Sacks, who is also a chemistry enthusiast, described the phenomenon as chemistry with a vengeance. Credit: Tor Paulin/Flickr Its the classic piece of chemical tomfoolery: take a lump of sodium or potassium metal, toss it into water and watch the explosion. Although this piece of pyrotechnics has amazed generations of chemistry students, until now it has been misunderstood, a paper inNature Chemistryreveals. The explosion, say Pavel Jungwirth and his collaborators at the Czech Academy of Sciences in Prague, is not merely a consequence of the ignition of the hydrogen gas that the alkali metals release from water. That may happen eventually, but it begins as something far stranger: a rapid exodus of electrons followed by explosion of the metal driven by electrical repulsion. The neurologist and celebrated author Oliver Sacks, who is also a chemistry enthusiast, described the phenomenon as chemistry with a vengeance in his bookUncle Tungsten.He wrote of how, as a boy, he and his friends bought a lump of sodium from the local chemicals supplier and dumped it into the Highgate Ponds in … Continue reading →

Canadian Society of Chemistry's 2014 Fred Beamish Award was awarded to Professor Juewen Liu The 2014 Fred Beamish Award was awarded to Professor Juewen Liu (Department of Chemistry, University of Waterloo). The Award Lecture titled "Lanthanide-dependent RNA-cleaving DNAzymes as metal biosensors" is published today in the Canadian Journal of Chemistry. Sponsored by the Canadian Society of Chemistry (CSC) Analytical Chemistry Division, the Fred Beamish Award is presented to an individual who demonstrates innovation in research in the field of analytical chemistry, where the research is anticipated to have significant potential for practical applications. Dr. Juewen Liu is a professor of chemistry at the University of Waterloo. He is also affiliated with the Waterloo Institute for Nanotechnology (WIN) and his current research involves biosensor development using DNA for target recognition. Professor Juewen Liu's lab has successfully accomplished the task of carrying out combinatorial selection to isolate lanthanide-dependent RNA-cleaving DNAzymes. They have developed a group of new DNA probes that are highly sensitive and specific to lanthanide ions. Lanthanide ions are known as "industrial vitamins" and they increase materials performance with a small amount of doping. These new DNA probes can potentially be used to develop a biosensor array for lanthanide and … Continue reading →
