3D X-ray of chip interiors Researchers from the Paul Scherrer Institute, EPFL Lausanne, ETH Zurich, and the University of Southern California used X-rays to take non-destructive, three-dimensional images of the inside of a microchip at 4 nanometer resolution. To create the images, the researchers relied on a technique called ptychography, in which a computer combines many individual images ... » read more

Okinawa Institute of Science and Technology proposed a new EUV litho technology using only four reflective mirrors and a new method of illumination optics that it claims will use 1/10 the power and cost half as much as existing EUV technology from ASML. Applied Materials may not receive expected U.S. funding to build a $4 billion research facility in Sunnyvale, CA, due to internal government... » read more

Long-term solar energy storage Researchers from Chalmers University of Technology and Universidad de La Rioja created a system capable of storing solar energy for extended periods of time. The system, called Molecular Solar Thermal Energy Storage (MOST), hinges on a molecular photoswitch made from carbon, hydrogen and nitrogen. When the molecule is hit by sunlight, it turns into an energy-rich... » read more

Asphalt anode Scientists at Rice University developed an anode for lithium metal batteries enabling them to charge 10 to 20 times faster than commercial lithium-ion batteries. The anodes are a porous carbon made from asphalt mixed with conductive graphene nanoribbons and coated with composite with lithium metal through electrochemical deposition. The lab combined the anode with a sulfurized... » read more

Healing perovskites A team from the University of Cambridge, MIT, University of Oxford, University of Bath, and Delft University of Technology discovered a way to heal defects in perovskite solar cells by exposing them to light and just the right amount of humidity. While perovskites show promise for low-cost, efficient photovoltaics, tiny defects in the crystalline structure, called traps,... » read more

From sun to hydrocarbon fuel Researchers at the University of Illinois at Chicago have engineered a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device converts atmosph... » read more
