A group of researchers at National Taiwan University, National Applied Research Laboratories in Taiwan, and the Research Center for Applied Sciences in Taiwan have found a potential novel use for old music CDs. They coated disks with zink oxide (ZnO) nanorods that can function as a photocatalyst, a substance which can promote the reaction without… »

While lithium-ion batteries present the most dominant rechargeable battery on the market, their limited energy density (energy stored per unit volume), high cost and safety problems drives various research groups to invent a battery with better performance. Stanford University researchers have developed an advanced zinc-air battery which could serve low-cost alternative to conventional lithium-ion batteries…. »

Current traditional methods used to produce hydrogen rely on natural gas which releases carbon dioxide during conversion. There are alternative ways that are yet to be improved, such as MIT’s Artificial Leaf and other artificial photosynthesis systems, and researchers from University of Delaware (UD) came up with a different approach by designing a reactor that… »

Even though silicon is one of the most abundant elements, the energy required to make silicon from sand is immense. A group of researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) developed a new nanopatterning technique which boosts the output of the cells, thus enabling manufacture of solar cells that are one… »
