Polylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, researchers have developed an eco-friendly process to make large amounts of lactic acid from glycerol, a waste by-product in the production of biodiesel.
The building sector accounts for 40 percent of primary energy consumption in Europe. Home owners seeking for energy efficiency are faced with confusing and sometimes contradictory information. Now, researchers have developed a smartphone app in the EU project ENBUS! that helps home owners calculate the tangible benefits of energy efficiency measures before investing.
The basic idea behind HYDRACT is to replace compressed air with water pressure as the power source for operating process valves. The water hydraulic technology can potentially be used for many other applications as a replacement for compressed air.
The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to 'match' different forms of alternative energy systems that provide an overall more steady flow of electricity, researchers say in a new report.
A report published today shows how electrons hop across otherwise electrically insulating areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of electrically conductive 'stepping stones'.
