According to The Economist, a battery design “being developed by Donald Sadoway of the Massachusetts Institute of Technology would use two sorts of liquid metal, separated by a liquid electrolyte.” Using metals of varying densities, Sadoway’s design would allow the substances to float as separate layers in a container.
Presidential Medal of Freedom recipient Prof. Mildred Dresselhaus speaks with Julianna Goldman of CBS Evening News about her career at MIT and what continues to inspire her to come to work seven days a week. "Every year there's something new that comes along that's too exciting to quit," says Dresselhaus.
A system developed by Prof. Alfredo Alexander-Katz allows microscopic devices to navigate a cell’s surface, reports Alissa Zhu for Popular Science. “Doctors could use them to provide real-time updates on internal structures or distribute drugs to specific targets within a body.”
David Weinberg of Marketplace reports that MIT researchers have developed a formula for concrete that reduces its greenhouse-gas emissions. Dr. Roland Pellenq explains that to make a “greener” cement, researchers examined concrete’s properties at the “sub-micron or big-nano level.”
Forbes reporter Bill Tucker writes about battery innovation, highlighting a liquid battery system developed by MIT researchers. The proposed system would operate at dramatically lower temperatures and would allow renewable energy sources to compete with conventional power plants, reports Tucker.
Mark Peplow writes for Nature about a new molten-metal battery designed by Professor Donald Sadoway’s team: “A battery made of molten metals could help to make sources of renewable energy more viable by storing the excess electricity generated by these intermittent sources.”
Professor Donald Sadoway’s team has designed a battery that makes use of molten metals, which could allow for large-scale power storage, reports Jonathan Webb for the BBC. “Previous battery designs have largely been too expensive to help store energy on the scale of a national power grid,” writes Webb.
MIT scientists have shown recycled lead can be used in solar cells, reports Popular Science’s Emily Gertz. “The group's work demonstrates that the perovskite created from the lead in just one old car battery could provide materials for 30 households-worth of solar energy cells,” writes Gertz.
Martin LaMonica writes for IEEE Spectrum about how MIT researchers have developed a system that uses car batteries to produce solar cells. “The beauty is that this new process is pretty interchangeable with the current production method,” says Prof. Angela Belcher.
Washington Post reporter Rachel Feltman writes that MIT engineers have developed a system that recycles batteries into solar cells. “We think it could be a competitor that’s easy to process, has rapidly increasing efficiency, and can be made in an environmentally friendly way,” says Prof. Angela Belcher.
David Pogue of the PBS show NOVA examines Professor Paula Hammond’s work developing a new type of vaccine that delivers a DNA patch via tiny microscopic needles. Using DNA as the vaccine is a “very unique but also very powerful” approach, Hammond explains.
Cynthia Graber of Scientific American reports on the new MIT technique to use solar energy to generate steam. Graber reports that the new system reaches, “85 percent efficiency in converting the solar energy into steam."
New York Times reporter Colin Nickerson writes about Professor Linn Hobbs’ research into whether the ancient Egyptians used a synthetic material to build the Great Pyramids. "It could be they used less sweat and more smarts," Hobbs told The New York Times.
Writing for Forbes, Neil Kane writes about new technology developed by MIT researchers that allows for solar energy to be captured when the sun is shining and stored for later use.
Atlantic reporter Todd Woody writes about how MIT researchers have developed a way to store solar energy in molecules. The energy inside the molecules can be stored forever and endlessly re-used so that solar power can be accessed even when the sun is not shining, Woody explains.
