Artificial photosynthesis gets big boost from new catalyst

22-Nov-2017

A new catalyst created by U of T Engineering researchers brings them one step closer to artificial photosynthesis -- a system that, just like plants, would use renewable energy to convert carbon dioxide (CO2) into stored chemical energy. By both capturing carbon emissions and storing energy from ...

Poly-(1-phospha-isoprene): phosphorus-containing natural rubber analogue

11-Jul-2017

Goodyear’s 1839 discovery of the vulcanization of natural rubber obtained from rubber trees marks the beginning of the modern rubber industry. A variety of synthetic rubber products were subsequently developed. Scientists have now introduced a new, interesting variant: a phosphorus-containing ...

A more sustainable way to refine metals

08-Jun-2017

A team of chemists in Canada has developed a way to process metals without using toxic solvents and reagents. The system, which also consumes far less energy than conventional techniques, could greatly shrink the environmental impact of producing metals from raw materials or from post-consumer ...

Cold conversion of food waste into renewable energy and fertilizer

02-Jun-2017

Researchers from Concordia's Department of Building, Civil and Environmental Engineering (BCEE) in collaboration with Bio-Terre Systems Inc. are taking the fight against global warming to colder climes. Their weapon of choice? Cold-loving bacteria. In a study authors Rajinikanth Rajagopal, David ...

Zinc oxide: It's not just for sunscreen and diaper cream!

11-May-2017

For many, zinc oxide conjures images of bright stripes down lifeguards' noses. But for researchers in Concordia's Faculty of Arts and Science, ZnO is an exciting compound with important optical and electrical properties. For a study Concordia physicists Amir Hassanpour and Pablo Bianucci joined ...

Bio-inspired catalysts that work in water open door to greener chemical processes

09-May-2017

Université Laval researchers have developed catalysts that, like enzymes present in living cells, are able to function efficiently in water. This discovery shows that it may be possible to substantially reduce the use of toxic and non-recyclable organic solvents in a host of chemical reactions, ...

Melting snow contains a toxic cocktail of pollutants

07-Apr-2017

With spring finally here and warmer temperatures just around the corner, snow will slowly melt away, releasing us from the clutches of winter. However, that's not the only thing that the melting snow will release. Researchers from McGill University and École de technologie supérieure in Montreal ...

How nanoparticles affect flow through porous stuff in surprising ways

06-Apr-2017

Those who have mixed oil and vinegar may have unknowingly observed a strange fluid phenomenon called fingering instability. A type of this phenomenon, called viscous fingering (VF), occurs in porous media where fluids of differing viscosity converge in finger-shaped patterns as a result of ...

The inner lives of molecules

06-Apr-2017

Quantum mechanics rules. It dictates how particles and forces interact, and thus how atoms and molecules work -- for example, what happens when a molecule goes from a higher-energy state to a lower-energy one. But beyond the simplest molecules, the details become very complex. "Quantum mechanics ...
