Changing fuel cell catalyst shape would dramatically increase efficiency, lower cost
May 25, 2017
An international team led by researchers at UCLA and Caltech has demonstrated how altering the form of platinum nanoscale wires from a smooth surface to a jagged one could dramatically reduce the amount of precious metal used as catalysts in fuel cells and lower the cost.

New spectroscopy technique provides unprecedented insights about the reactions powering fuel cells
May 25, 2017
Researchers at UCLA’s California NanoSystems Institute have developed a dramatically advanced tool for analyzing how chemicals called nanocatalysts convert chemical reactions into electricity. Current spectroscopy methods require large laboratory machines to measure chemical reactions, but the new technique uses a nanoelectronic chip to do the same thing while the reactions are taking place — which previously was very difficult — with better accuracy, and while gathering a completely new set of data.

2D semiconducting transistor breaks new record
May 25, 2017
Researchers at the University of California, Los Angeles, have succeeded in minimizing both the contact resistance and channel length in transistors made from the 2D semiconductor molybdenum disulphide, so making a device that has a high ON current of 0.83 mA/µm at 300K. This new work shows for the first time that 2D semiconducting transistors can compete with silicon-based ones in terms of performance – as defined by the International Technology Roadmap for Semiconductors (ITRS).
