New findings could reveal mechanism behind zero-energy-loss current-carrying capability

In the search for understanding how some magnetic materials can be transformed to carry electric current with no energy loss, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have made an important advance: Using an experimental technique they developed to measure the energy required for electrons to pair up and how that energy varies with direction, they've identified the factors needed for magnetically mediated superconductivity - as well as those that aren't.

New record efficiency for dye solar cells

Announced today in the prestigious scientific journal, Nature, is a paper by a team led by Professor Michael Graetzel describing a new deposition process to create the light harvesting pigment for solid-state dye solar cells. Cells fabricated using this technique have established a new world record efficiency of 15% for a solid-state Dye Solar Cell.

Department of Energy lab field study will sample aerosols from biomass burning

Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL), working with colleagues from Pacific Northwest National Laboratory (PNNL), will conduct a field campaign this summer and fall in the skies over the Pacific Northwest and Tennessee to measure the evolution of aerosols in wildfires and prescribed agriculture burns, respectively.

Crystal clear solutions for low-cost and efficient solar power

The CRYSTAL CLEAR (Crystalline silicon photovoltaic: low-cost, highly efficient and reliable modules) project focused on crystalline silicon modules, which are used in around 9 out of 10 solar energy systems sold worldwide. The project partners focused on developing state-of-the-art manufacturing technologies that reduced the production cost of solar modules to around EUR 1 for each watt produced.

Prototype for the CO2 vacuum cleaner

ETH-Zurich spin-off Climeworks is looking to filter carbon dioxide out of the ambient air and sell it to major customers such as greenhouses at competitive prices. The first pilot plant is up and running and the equipment is expected to filter up to 1,000 tons of carbon dioxide out of the air a year by 2014.
