Researchers have designed a device that delivers two medications that help stop HIV transmission.

Although condom usage is the best strategy for preventing HIV transmission, the researchers are working to design a device that can be used by sex workers and in situations where women are not in a position to negotiate condom use.

Metal catalysts used for environmental sustainability found to degrade and become less effective

New research is showing that some tiny catalysts being considered for industrial-scaled environmental remediation efforts may be unstable during operation.

Chemists from the University of Waterloo studied the structures of complex catalysts known as “nanoscale electrocatalysts” and found that they are not as stable as scientists once thought. When electricity flows through them during use, the atoms may rearrange. In some cases, the researchers found, electrocatalysts degrade completely.
