Scientists at the Department of Energy’s Oak Ridge National Laboratory used carefully planned chemical design, neutron scattering and high-performance computing to help develop a new catalytic recycling process. The catalyst selectively and sequentially deconstructs multiple polymers in mixed plastics into pristine monomers. The new organocatalyst has proven to efficiently and quickly deconstruct multiple polymers — in around two hours. Such polymers include those used in materials such as safety goggles (polycarbonates), foams (polyurethanes), water bottles (polyethylene terephthalates) and ropes or fishing nets (polyamides), which together comprise more than 30% of global plastic production. Until now, no single catalyst has been shown to be effective on all four of these polymers.

Researchers at McMaster and the University of Guelph have discovered a convenient new way to track levels of omega-3 fatty acids in the bloodstream, making it much easier to access information that is critical to cardiovascular and cognitive health, but which has previously been challenging to gather. While the human body can generate most of the fats it needs, it cannot produce adequate levels of omega-3 fatty acids and must obtain them from dietary sources. Two key omega-3 fatty acids, called EPA (eicosatetraenoic acid), and DHA (docosahexaenoic acid), can be derived only from certain sources, such as fish, seafood, enriched foods, and supplements, but measuring how much gets into the blood has been both difficult and invasive.
