The first episode of SCIENCE at nanoscale features Dr. Jasmin Kaur, an expert in developing general theory to help study the importance of tuning local work function of metal electrode surface for better electrochemical efficiency. Jasmin, in her PhD work, predicted the effect of size and shape of metal nanoparticles on the local work function in addition to the effect of solvent surroundings. We, in this episode, get into deep dive discussion to further understand the implications of her theoretical results on better catalyst designs for electrochemical systems.
