(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...
A research team led by scientists from City University of Hong Kong (CityU) has recently designed a structured thermal armor (STA) that achieves efficient liquid cooling even over 1,000°C, fundamentally solving a 266-year-old ...
