Mathematically designed graphene has improved electrocatalytic activity

An international research group has improved graphene’s ability to catalyze the ‘hydrogen evolution reaction,’ which releases hydrogen as a result of passing an electronic current through water. They designed a mathematically predicted graphene electrocatalyst, and confirmed its performance using high resolution electrochemical microscopy and computational modelling.

Engineered bacteria could be missing link in energy storage

One of the big issues with sustainable energy systems is how to store electricity that’s generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution.

Artificial photosynthesis transforms carbon dioxide into liquefiable fuels

Chemists have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess carbon dioxide to store solar energy — in the form of chemical bonds — for use when the sun is not shining and in times of peak demand.

Good vibrations: Using piezoelectricity to ensure hydrogen sensor sensitivity

Researchers have developed a new method that uses piezoelectric resonance to improve the manufacture of highly sensitive hydrogen sensors. By optimizing the gaps between palladium nanoparticles in the devices, they were able to increase the sensitivity by a factor of 12 over palladium nanoparticles fabricated by previous methods. The work in this study is important for the development of new sensing devices that are capable of detecting hydrogen at low concentration.
