Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have created a composite material that they claim can store hydrogen densely and safely, yet that also allows it to be easily accessed for creating electricity. Some materials that are currently used for hydrogen storage have a relatively small capacity, and need to be superheated or supercooled in order to work at peak efficiency. The new material, however, is said not to have either of these limitations.  Read More

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have come a step closer to the development of a commercially-viable full-spectrum solar cell. Traditionally, due to their limited band gap (energy range), semiconductors used in solar cells have only been able to respond to a certain segment of the solar spectrum – this segment varies, according to the semiconductor. Some cells have been created that respond to everything from low-energy infrared through visible light to high-energy ultraviolet, but these have been costly to produce and thus unfit for common use. The new cell, however, responds to almost the entire spectrum, and can be made using one of the semiconductor industry’s most common manufacturing processes.  Read More

It seems hard to believe that glass could be stronger than steel, but a team of researchers has developed a super-strong metallic glass that has incredible plasticity when placed under stress, making it as strong and tough as metal. Typically, the structure of glass is strong but brittle which can cause cracks to develop and spread. The new metallic glass features palladium which has a high “bulk-to-shear” stiffness ratio. This allows the metallic glass to bend rather than crack – giving it a fracture toughness that goes beyond the limits of some of the strongest and toughest materials known.  Read More

The biofuel industry stands to benefit from the development of a new variety of yeast which produces ethanol from plant products more efficiently. Engineered by combining two existing yeast species, the new strain can simultaneously consume two types of sugar commonly found in plants to produce ethanol.  Read More
