New type of sensor material developed

29-Mar-2017 - Hokkaido University scientists have succeeded in developing a nickel complex that changes color and magnetism when exposed to methanol vapor. The new material can potentially be used not only as a chemical sensor, but also with future rewritable memory devices. The phenomenon of color changes in ...

Understanding properties of nanoparticles and quantum dots using Hansen Solubility Parameters

16-Nov-2016 - Devices based on quantum dots and smart nanoparticles are currently getting a lot of attention. For instance, the colours, contrast and brightness of displays based on quantum dots provide benefits for users of TVs and phones. In addition, such particles can create value when incorporated into ...

How solvent molecules cooperate in reactions

10-Oct-2016 - Molecules from the solvent environment that at first glance seem to be uninvolved can be essential for chemical reactions. This has been shown by researchers studying the formation of an ether in pure solvents and in their mixtures. They explained the underlying mechanisms in detail using ...

Measuring chemistry: local fingerprint of hydrogen bonding captured in experiments

21-Mar-2016 - A team from Helmholtz-Zentrum Berlin has been able for the first time to measure how new bonds influence molecules: they have reconstructed the “energy landscape” of acetone molecules using measurement data from the Swiss Light Source (SLS) of the Paul Scherrer Institut, and thereby empirically ...

A breakthrough for organic reactions in water

01-Jul-2014 - Green-chemistry researchers at McGill University have discovered a way to use water as a solvent in one of the reactions most widely used to synthesize chemical products and pharmaceuticals. The findings mark a potential milestone in efforts to develop organic reactions in water. Chao-Jun Li and ...

New labs sprouting up to test cannabis — and the law

13-Dec-2013 - Grandaddy Purple, Blueberry Yum Yum and other pot products may now be legal for medical use in 20 states and the District of Columbia, but how do patients know what dose they’re really getting and whether it’s safe? Small labs are setting up shop — some at their own legal peril — to help patients ...

Help from the Dark Side

Using “dark channel” fluorescence, scientists can explain how biochemical substances carry out their function

09-Aug-2010 - Spectroscopic techniques are among the most important methods by which scientists can look inside materials. They exploit the interaction of light waves with a given sample. Now, using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) have ...

SGE Analytical Science: eVol Wins prestigious R&D100 Technology Innovation Award

20-Jul-2010 - eVol®, the world’s first automated analytical syringe created and manufactured by SGE Analytical Science, has been selected as a 2010 R&D100 Award winner. eVol® is a unique laboratory tool that removes the human limitation of manual liquid handling delivering significantly improved levels of ...

Boron-Oxygen Triple Bonds stabilized for the first time ever

20-Apr-2010 - World first: chemists from the University of Würzburg have, for the first time ever, succeeded in creating a stable triple bond between the elements boron and oxygen. This success is reported in the journal "Science". Why is this renowned scientific magazine so enthusiastic about the work of the ...

Chemist monitors nanotechnology's environmental impact

31-Mar-2010 - Interest in 'green' innovation means not just thinking big but also very, very, very small. At least that's the way Omowunmi Sadik, director of Binghamton University's Center for Advanced Sensors and Environmental Systems, sees it. She's working to develop sensors that would detect and identify ...
