But what happens when you get covered in poison ivy and can't stop scratching? Jennifer Novotney, winner of the 2014 Chemistry Champions science communications competition, breaks down what it is about that dreaded vine that makes us so itchy. Reactions also offers up a remedy for the poison ivy's itch using the power of chemistry. Check out the video here: http://youtu.be/SJEU3PT0O5g. ### The American Chemical Society (ACS) is looking for the next great science communicator. We're bringing back the Chemistry Champions contest for 2015! The first round asks scientists to explain their research to the general public in a fun two-to-three-minute video. If you think you're the Carl Sagan of chemistry, check out http://www.acs.org/chemchamps for more details.

IMAGE:Can individual components be precisely detected in the crowd of chemicals that make up a mixture? At the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw,... view more Credit: IPC PAS, Grzegorz Krzy?ewski Elements and their compounds will no longer be able to hide in mixtures, even if the latter are made up of many components. The end of chemical incognito is a result of the development at Warsaw's Polish Academy of Science's Institute of Physical Chemistry of a new, much more accurate method of identifying the "fingerprints" of chemical substances, imprinted in the light dispersed by the mixtures. Elements and chemical compounds exist in their pure form only in laboratories. The world of nature is a world of multi-component additives and mixtures. Can individual components be precisely detected in the crowd of chemicals that make up a mixture? Can this be done purely by examining the light scattered by the mixture? To date, not only did current methods of spectral analysis not determine all of the components, but they even suggested the presence of compounds that were simply not there. However, now detection of the components of a mixture will be much more reliable - … Continue reading →

Calvin Giddings Award for Excellence in Education. view more Credit: UT Arlington ARLINGTON, Texas -- Purnendu "Sandy" Dasgupta, the Jenkins Garrett Professor of Chemistry at The University of Texas at Arlington, has received the 2015 American Chemical Society Division of Analytical Chemistry J. Calvin Giddings Award for Excellence in Education. The national award recognizes a scientist who has enhanced the professional development of analytical chemistry students, developed and published innovative experiments, designed and improved equipment or teaching labs and published influential textbooks or significant articles on teaching analytical chemistry. "I am a third generation university teacher. So, much of this honor I can credit to my father and grandfather -- I am merely carrying on that tradition," Dasgupta said. "I am especially honored by this award. I have been recognized for some research accomplishments or other in the past but this one recognizes for the first time my commitment to and love for teaching and that is why it is so gratifying." UT Arlington President Vistasp M. Karbhari said Dr. Dasgupta's newest honor demonstrates the high quality of University faculty as exceptional models for advanced … Continue reading →

IMAGE:An antibacterial dressing with gold nanocomposites is presented by Dr. Katarzyna Wybranska from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, Poland. view more Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, will in future help to improve the hygiene of sportswear, and used in medicine, will reduce the rate of infections and shorten the times of in-patient hospital admissions. How do you speed up wound healing? How do you shorten the minimum in-patient stay in hospital and cut down the associated cost? Here's one answer: dressings with antibacterial coatings, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw. The new method of producing nanocomposite antibacterial coatings is universal and can be used to modify the surfaces of various materials. After modification, the materials exhibit excellent antiseptic properties, whilst remaining very friendly to human cells. The coatings' usefulness is not limited to the field of medicine: they can be used, for example, to improve the level of hygiene of everyday items of clothing such as socks, insoles, … Continue reading →

Young chemist receives prize for her outstanding research on zoom-time-of-flight mass spectrometry IMAGE:Elise Dennis is the recipient of the Analytical and Bioanalytical Chemistry Best Paper Award 2014. view more Credit: Elise Dennis Elise Dennis (27) is the recipient of the Best Paper Award 2014, presented by the Springer journal Analytical and Bioanalytical Chemistry (ABC). In a paper published in ABC, lead author Dennis and her colleagues demonstrate the performance of a new concept called zoom-time-of-flight mass spectrometry (zoom-TOFMS). The award, accompanied by 1,500 euros, was created by Springer to honor exceptional young scientists and to stimulate their research careers. The ABC Best Paper Award has been given since 2005. Dennis's study demonstrates the unique advantages of alternating between constant-momentum acceleration and conventional, constant-energy acceleration, which include an improvement in mass resolution without a loss in instrument sensitivity. The new method is expected to be amenable to retrofitting onto existing time-of-flight mass spectrometers. Elise Dennis received her B.S. with honors from the College of William and Mary (USA) and is currently a Ph. D. candidate in analytical chemistry at Indiana University Bloomington (USA) under the direction of Prof. Gary M. Hieftje. Her work pushes the boundaries of time-of-flight mass spectrometry with … Continue reading →
