At Hokkaido University, researchers have created a layered cobalt oxide that features a record-setting thermoelectric figure of merit, which can be useful to improve the thermoelectric power generation.
Hiromichi Ohta Waste heat is a highly promising source of renewable energy; however, the efficiency of using heat to generate energy has historically been much lower than hydroelectric, wind or solar power. While there are a number of materials that can be used for the generation of energy from waste heat, they all suffer from various issues ranging from low stability to low efficiency. Nevertheless, the fact that a large number of industries generate copious amounts of waste heat have driven research into this field. A team of scientists led by Professor Hiromichi Ohta at the Research Ins...

Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these cables would have less signal loss if it were manufactured under high pressure. "Signal loss means that we have to use amplifiers every 80 to 100 kilometers (50 to 62 miles)," said John C. Mauro, profess...
