Via CNET’s Green Tech blog, we bring you a video about some nifty power conversion technology for photovoltaic applications that Freescale Semiconductor unveiled this week at the Applied Power Electronics Conference and Exposition. This is about high efficiency, ultra-low-voltage DC-to-DC converter technology. It enables IC startup thresholds to be reduced to 0.32 V (ICs typically can’t…
Read More(the following is a guest post from Abdul-Majeed Azad, associate professor, chemical engineering, University of Toledo) As we know, the ultimate chemical fate of the conventional fossil fuel combustion is always CO2 and H2O, two well-known greenhouse gases responsible for contributing considerably to the global warming. In 2007 the global level of CO2 was 30…
Read More(corrected, courtesy of the comments from Dale Bentz, below) The “verdict” is in – engineers at the National Institute of Standards and Technology say they have developed a technique that promises to double the service life of concrete. The soon-to-be patented method is the result of a project called VERDiCT – Viscosity Enhancers Reducing Diffusion…
Read MoreBack in August, we noted the work Daniel Nocera a professor of chemistry at MIT, who is leading has developed an unprecedented electrolysis process that uses the sun’s energy to split water molecules into oxygen and hydrogen gases. The gases can then be stored and later run through a fuel cell to produce electricity as…
Read MoreThe American Ceramic Society has now posted videos of four lectures presented last October as part of the Society’s annual meeting. Each of the lectures is approximately one-hour in length and presented in a “YouTube” level of quality to provide the most ease in viewing. Each of the lectures is presented by a luminary in…
