Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.
Uranium mining for the nuclear industry causes immense environmental damage, which becomes more severe as reserves are depleted. The isolation of uranium from seawater would be a much more environmentally friendly alternative. In the journal Angewandte Chemie, American researchers have now introduced a process by which they can produce tailored, highly effective adsorption agents to do this job.
12 billion aerosol sprays, gels and foams are manufactured annually; over 500,000 tons of gas (used as a propellant in aerosols) contribute to the expensive packaging and environmental danger of today's aerosol canisters. An Israeli company, GreenSpense, has developed an eco-friendly solution to the challenges and dangers presented by aerosol containers.
The U.S. Photovoltaic Manufacturing Consortium (PVMC), an industry-led collaboration headquartered at SUNY’s College of Nanoscale Science and Engineering (CNSE) in New York that is designed to accelerate next-generation solar photovoltaic (PV) technologies, has released the first-ever U.S. CIGS PV Roadmap reports.
A discovery at the University of Wisconsin-Madison may represent a significant advance in the quest to create a "hydrogen economy" that would use this abundant element to store and transfer energy.
Thomas Swan are hoping their plans to have an Anaerobic Digester (AD) plant on the site the company has occupied since 1926 are given the green light. Designs for this safe, clean and unobtrusive way to produce low carbon sustainable energy have been submitted and local residents were given the opportunity to ask questions and voice any concerns at a ‘drop-in’ sessions in Crookhall Community Centre.
The Photovoltaics-Laboratory (PV-Lab) of EPFL's Insitute of Microengineering (IMT), founded in 1984 by Prof. Arvind Shah and now headed by Prof. Christophe Ballif, is well known as a pioneer in the development of thin-film silicon solar cells, and as a precursor in the use of microcrystalline silicon as a photoactive material in thin-film silicon photovoltaic (TF-Si PV) devices.
FoodChek Systems Inc. ("FoodChek" or the "Corporation") is very proud to announce that the AOAC Research Institute, the approval body for all U.S. food safety tests, has validated and certified as a Performance Tested Method ("PTM"), FoodChek's patent pending Actero(tm) Listeria Enrichment Media (License #111201) and the FoodChek(tm) Listeria spp. Assay Cassette (License #111202).
“Exceeding Expectations: Cleantech Entrepreneur Roundtable”
Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.
