Photovoltaics from any Semiconductor

“It’s time we put bad materials to good use,” says physicist Alex Zettl, who led this research along with colleague Feng Wang. “Our technology allows us to sidestep the difficulty in chemically tailoring many earth abundant, non-toxic semiconductors and instead tailor these materials simply by applying an electric field.”

Forecast: More Than 260 Million Tons of Waste per Year Will Be Converted to Energy by 2022

According to a recent report from Pike Research, a part of Navigant’s Energy Practice, more than 800 thermal waste-to-energy plants operate in nearly 40 countries around the globe – a number that is expected to grow rapidly over the next decade. By 2022, Pike Research forecasts, at least 261 million tons of municipal solid waste (MSW) will be converted to base load power and heat.

Yissum Introduces a Novel Biocontrol Method for Protecting Plants from Pathogens Using Yeast Isolated from Strawberry Leaves

the widespread use of chemical pesticides has resulted in severe environmental pollution, and many pathogens are developing resistance to existing chemicals. In addition, many pesticides are now banned for use, and organic farming is not allowed to rely on such substances at all. A major goal, therefore, is to develop new, environmentally-friendly tools to control pathogens.

Cleaning with Sunlight Using Photocatalytic Plastics

When these titanium dioxide molecules are ‘activated’ by the UV light in the sun’s rays, they act as a kind of catalyst, triggering an electrochemical reaction which produces free radicals. These and other active molecules strike a fatal blow to bacteria, fungi and similar organisms, first destroying the cell walls and then penetrating the cytoplasm – the substance that fills the cell – and damaging the bacteria’s DNA. As a result, the organic substances are destroyed instead of remaining stuck to the surface.
