From ocean waves and flowing rivers to the systems used to transport and treat water, vibrations are everywhere. But can vibrations do more than just shake water? Can they split water or drive the production of useful chemicals from water? A research team led by Professor Sai Kishore Ravi from the School of Energy and Environment (SEE) at City University of Hong Kong (CityUHK) has successfully demonstrated how mechanical vibrations can be harnessed to drive the production of useful chemicals from water.
