Mathematically designed graphene has improved electrocatalytic activity

An international research group has improved graphene's ability to catalyse 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. The findings were published in the journal Advanced Science.

MobiKa: A low-cost mobile robot that can assist people in a variety of settings

Researchers at Fraunhofer IPA, in Stuttgart, Germany, have recently developed MobiKa, a low-cost, mobile robot capable of two-modal (voice and text) interactions with humans. Their robot, presented in a paper pre-published on arXiv, could be particularly useful for assisting elderly people.
