Livermore and Russian scientists propose new names for elements 114 and 116
— 2 Dec 2011 10:17The International Union of Pure and Applied Chemistry (IUPAC) today recommended new proposed names for elements 114 and 116, the latest heavy elements to be added to the periodic table…
Artificial leaf could debut new era of 'fast-food energy'
— 2 Dec 2011 09:41Technology for making an 'artificial leaf' holds the potential for opening an era of 'fast-food energy,' in which people generate their own electricity at home with low-cost equipment perfect for the 3 billion people living in developing countries and even home-owners in the United States. That's among the prospects emerging from research on a new genre of 'electrofuels' described in the current edition of Chemical and Engineering News, the American Chemical Society's weekly newsmagazine…
Graphene lights up with new possibilities
— 29 Nov 2011 21:40The future brightened for organic chemistry when researchers at Rice University found a highly controllable way to attach organic molecules to pristine graphene, making the miracle material suitable for a range of new applications…
Scientists develop brand new class of small molecules through innovative chemistry
— 20 Nov 2011 18:36Inspired by natural products, scientists on the Florida campus of The Scripps Research Institute have created a new class of small molecules with the potential to serve as a rich foundation for drug discovery. The study, led by Scripps Research Associate Professor Glenn Micalizio, was published 20 November in an advanced online edition of the journal Nature Chemistry…
New 'smart' material could help tap medical potential of tissue-penetrating light
— 16 Nov 2011 21:39Scientists are reporting development and successful initial testing of the first practical 'smart' material that may supply the missing link in efforts to use in medicine a form of light that can penetrate four inches into the human body. Their report on the new polymer or plastic-like material, which has potential for use in diagnosing diseases and engineer new human tissues in the lab, appears in ACS' journal Macromolecules…
Formaldehyde: Poison could have set the stage for the origins of life
— 6 Apr 2011 17:22Formaldehyde, a poison and a common molecule throughout the universe, is likely the source of the solar system's organic carbon solids - abundant in both comets and asteroids. Scientists have long speculated about the how organic, or carbon-containing, material became a part of the solar system's fabric. New research from Carnegie's George Cody, along with Conel Alexander and Larry Nittler, shows that these complex organic solids were likely made from formaldehyde in the primitive solar system. Their work is published online April 4 by the Proceedings of the National Academy of Sciences…
Exploring the possibilities for zeolites
— 6 Apr 2011 15:43Some people collect stamps and coins, but when it comes to sheer utility, few collections rival the usefulness of Rice University researcher Michael Deem's collection of 2.6 million zeolite structures…
Microreactors: Small scale chemistry could lead to big improvements for biodegradable polymers
— 1 Apr 2011 15:27Using a small block of aluminium with a tiny groove carved in it, a team of researchers from the National Institute of Standards and Technology (NIST) and the Polytechnic Institute of New York University is developing an improved 'green chemistry' method for making biodegradable polymers. Their recently published work is a prime example of the value of microfluidics, a technology more commonly associated with inkjet printers and medical diagnostics, to process modelling and development for industrial chemistry…
Small code change, big effect
— 28 Mar 2011 18:02Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have developed a new method which enables researchers to label any protein of their choice with any of a wide variety of previously available compounds, in living cells, by introducing a single reactive artificial amino acid. Published today in Angewandte Chemie, the new technique enables researchers to label even rare proteins very precisely for optical imaging and in the future likely also for Magnetic Resonance Imaging (MRI)…
New imaging technique provides rapid, high-definition chemistry
— 21 Mar 2011 16:32With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM), led a team of researchers from UWM, the University of Illinois at Urbana-Champaign and University of Illinois at Chicago (UIC) to demonstrate these new capabilities…
