'Artificial leaf' converts harmful carbon dioxide into useful alternative fuel
07-Nov-2019
Scientists have created an "artificial leaf" to fight climate change by inexpensively converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology, outlined in a paper published in the journal Nature Energy, was inspired by the way plants use energy from sunlight to ...
Rocket fuel that's cleaner, safer and still full of energy
09-Apr-2019
Research published in Science Advances shows that it may be possible to create rocket fuel that is much cleaner and safer than the hypergolic fuels that are commonly used today. And still just as effective. The new fuels use simple chemical "triggers" to unlock the energy of one of the hottest ...
Powder could help cut CO2 emissions
20-Dec-2018
Scientists at the University of Waterloo have created a powder that can capture CO2 from factories and power plants. The powder, created in the lab of Zhongwei Chen, a chemical engineering professor at Waterloo, can filter and remove CO2 at facilities powered by fossil fuels before it is released ...
Albemarle’s ribbon cutting ceremony
17-Dec-2018
Malvern Panalytical announced that a ribbon cutting ceremony marking the successful installation of the Claisse® rFusion system for Albemarle Corporation was held on May 2, 2018 in Bayport, TX (USA). This event celebrates the achievement of a major project that will provide customers with ...
The Secret Contamination of Polar Bears
Hundreds of unrecognized halogenated contaminants discovered in polar bear serum
05-Dec-2018
Using a new approach to measure chemical contaminants in polar bears, scientists from Canada and the United States found a large variety of new chlorinated and fluorinated substances, including many new polychlorinated biphenyl metabolites. Worryingly, these previously unrecognized contaminants ...
Advance ability to control chemical reactions
Discovery offers a taste of the 'forbidden fruit' of reaction dynamics
09-Oct-2018
Scientists at the University of Toronto have found a way to select the outcome of chemical reaction by employing an elusive and long-sought factor known as the 'impact parameter'. The team of U of T chemists, led by Nobel Prize-winning researcher John Polanyi, have found a means to select the ...
Household cleaning products may contribute to kids' overweight by altering their gut microbiota
19-Sep-2018
Commonly used household cleaners could be making children overweight by altering their gut microbiota, suggests a Canadian study published in CMAJ (Canadian Medical Association Journal) . The study analyzed the gut flora of 757 infants from the general population at age 3-4 months and weight at ...
Not too wet, not too dry: plasma-treated fuel cell gets it just right
11-Sep-2018
Fuel cells hold promise as a clean, renewable source of energy. But keeping them dry has long been a challenge, as they produce water during the process of converting hydrogen and oxygen into electricity. Now University of British Columbia researchers say they may have found a solution: ...
Antibacterial Polymers
Surprising antibacterial activity and selectivity of hydrophilic phosphonium polymers
10-Sep-2018
Artificial polymers, like antibiotic peptides, need both hydrophobic and hydrophilic domains in their molecular structure to exert antibacterial activity. Now, researchers from Canada have synthesized a phosphonium polymer that challenges this view. As outlined in the journal Angewandte Chemie, ...
Bacteria-powered solar cell converts light to energy, even under overcast skies
06-Jul-2018
University of British Columbia researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright ...
