IMAGE:This is a pictorial representation of the main idea of click chemistry used at the Institute of Physical Chemistry of the Polish Academy of Sciences, Warsaw, Poland, to bond gold... view more Nanoparticles of various types can be quickly and permanently bonded to a solid substrate, if one of the most effective methods of synthesis, click chemistry, is used for this purpose. The novel method has been presented by a team of researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences, Warsaw, Poland. A small movement of the hand, the characteristic 'click!' - and the snap fastener quickly and securely fastens our clothes. One of the newest methods of synthesis in modern chemistry, click chemistry, works on a similar basis. Here, molecules are combined to form new chemical compounds by means of chemical 'snaps'. The method has so far been used mainly for the synthesis of more complex organic compounds. Now at the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw, Poland, they have managed to show that click chemistry chemical snaps can quickly, effectively and permanently bond much larger structures: gold nanoparticles to a glassy carbon substrate. The main … Continue reading →

Findings on patent-pending HER catalyst Ni5P4 reported in Royal Society of Chemistry's Energy & Environmental Science; operating stability and efficiency to be tested over extended time periods in commercial electrolyzers and fuel cells IMAGE:Shown are Rutgers University chemistry professors Martha Greenblatt and Charles Dismukes in a laboratory on the Busch Campus in Piscataway. view more PISCATAWAY, N.J. (March 18, 2015) - New research published by Rutgers University chemists has documented significant progress confronting one of the main challenges inhibiting widespread utilization of sustainable power: Creating a cost-effective process to store energy so it can be used later. "We have developed a compound, Ni5P4 (nickel-5 phosphide-4), that has the potential to replace platinum in two types of electrochemical cells: electrolyzers that make hydrogen by splitting water through hydrogen evolution reaction (HER) powered by electrical energy, and fuel cells that make electricity from combining hydrogen and oxygen," said Rutgers Chemistry Professor Charles Dismukes. "Platinum is the benchmark material for both devices as it has the best conversion efficiency. However, while platinum may be acceptable for making jewelry and low volume specialty applications, it is too expensive for large-scale applications such as energy storage and conversion. Our new HER catalyst, Ni5P4, has the … Continue reading →

Glen Ridge's three sets of brothers, from left: Max Thompson, Julian Thompson, Ryan Liddy, Tyler Liddy, David Weissenberger and Jack Weissenberger. The Glen Ridge boys basketball teams success this season relied a lot on the chemistry its three sets of brothers brought to the table. Julian and Max Thompson, Jack and Dave Weissenberger, and Ryan and Tyler Liddy all brought a family mentality to this years squad. The fact that this was one of the best seasons the program has had shows that chemistry goes a long way. "Being on the court with my brother made it easier to know where everyone else on the court was," said Julian, one of the teams senior captains. "It was helpful because we played together for a long time. I knew which passes he can catch, his speed ability and when hed be open." "Were all friends outside of the team as well," said senior Jack Weissenberger, who was also a captain along with Julian and Zach Thomas. "We hang out and get lunch together all the time. Its especially good with players like Julian and Max because we grew up playing basketball with them since middle school. So its all about being … Continue reading →

WALTHAM, MA--(Marketwired - March 19, 2015) - Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the publication of Food, Energy, and Water: The Chemistry Connection, edited by Dr. Satinder Ahuja. It is being introduced at the upcoming American Chemical Society's Annual Meeting and Exposition, where this year's theme is "Chemistry of Natural Resources." Elsevier is displaying this book and three other just-published chemistry titles at booth #211 at the Colorado Convention Center in Denver, March 22-24, 2015. Food, Energy, and Water examines the challenges of the food-energy-water nexus from a chemistry perspective within a multi-disciplinary domain. It includes the latest research on critical topics such as fracking, water use conflicts, and sustainability in food production cycles. The book offers today's scientists the background information necessary to fully understand the inextricable link between food, energy and water. It also discusses how this conceptual framework should form the basis for all contemporary research and development in chemistry in particular, and the sciences in general. Dr. Ahuja is an expert on improving water quality and has organized numerous global symposia on this topic. He worked for Novartis Corp. in various leadership positions for more than 25 … Continue reading →
