A new wrinkle in the control of waves. Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to sound suppression, and could […]
The battery is the biggest limitation for electric vehicles (EV). Tesla, General Motors, Nissan and others install heavy batteries that limit vehicle range and performance. The batteries take up as much as 15% of the vehicle’s total weight.
Prieto Battery’s copper foam. Power plants, wind farms, and smartphones all suffer from the same basic ailment — they lack cheap, reliable, long-life batteries to store large amounts of energy for when the sun goes down, the wind stops blowing, or the device is unplugged for a long time.
Researchers unveil the first working computer built entirely from carbon nanotube transistors. A group of researchers at Stanford University have moved a step closer to answering the question of what happens when silicon, the standard material in today’s microelectronic circuits, reaches its fundamental limits for use in increasingly small transistors.
UCLA smartphone virus scanner Scientists have finally developed a technology that makes it possible to avoid a trip to the doctor. The UCLA Henry Samueli School of Engineering and Applied Science scientists have created a lightweight, virus-detecting device that attaches to a common smartphone and is able to scan the human body for human cytomegalovirus (HCMV) […]
Hybrid optoelectronic nanostructures with controlled variation in photoconduction properties. University of Pennsylvania reasearchers have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.
University of Rochester researchers recently demonstrated how beams of light can actually levitate nanoscale diamonds. And while they’re not actually suggesting that we construct a light-driven hoverboard made of the precious gems, the things we might be able to do with floating diamonds are pretty cool in their own right.
University of Maryland engineers are currently working on a battery made of wood, an innovative, low-cost, environmentally friendly idea. The research team used tiny wood fibers from yellow pine trees to make test batteries — and we mean seriously tiny, the tree fibers are a thousand times thinner than a piece of paper. They use sodium rather […]
The research effort will attempt to design a vaccine conferring immunity to nicotine, using nanotechnology. At Arizona State University’s Biodesign Institute, Yung Chang and her colleagues have launched an ambitious new project designed to attack nicotine dependence in a radically new way.
