Pushing material boundaries for better electronics

Undergrads, take note: The lessons you learn in those intro classes could be the key to making your next big discovery. At least, that’s been the case for MIT’s Jeehwan Kim. A recently tenured faculty member in MIT’s departments of Mechanical Engineering and Materials Science and Engineering, Kim has made numerous discoveries about the nanostructure […]

Technique could improve the sensitivity of quantum sensing devices

In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image the brain with unprecedented detail, for example, or air traffic control systems with precise positioning accuracy. As many real-world quantum […]

Benchtop test quickly identifies extremely impact-resistant materials

An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What’s more, the specific structure matters, with some being more resilient to impacts than others. That’s what MIT engineers are finding in experiments with microscopic metamaterials — materials that are intentionally printed, assembled, […]

A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets, MIT study finds

Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical feature in their atmospheres. The researchers propose that if a terrestrial planet has substantially less carbon dioxide in […]

A mineral produced by plate tectonics has a global cooling effect, study finds

MIT geologists have found that a clay mineral on the seafloor, called smectite, has a surprisingly powerful ability to sequester carbon over millions of years. Under a microscope, a single grain of the clay resembles the folds of an accordion. These folds are known to be effective traps for organic carbon. Now, the MIT team […]

MIT physicists turn pencil lead into “gold”

MIT physicists have metaphorically turned graphite, or pencil lead, into gold by isolating five ultrathin flakes stacked in a specific order. The resulting material can then be tuned to exhibit three important properties never before seen in natural graphite. “It is kind of like one-stop shopping,” says Long Ju, an assistant professor in the Department […]

Bringing the environment to the forefront of engineering

In a recent podcast interview with MIT President Sally Kornbluth, Associate Professor Desirée Plata described her childhood pastime of roaming the backyards and businesses of her grandmother’s hometown of Gray, Maine. Through her wanderings, Plata noticed a disturbing pattern. “I was 7 or 8 when I caught wind of all the illness,” Plata recalls. “It […]

From a five-layer graphene sandwich, a rare electronic state emerges

Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire of carbon atoms linked in a hexagonal lattice. Despite its […]

Physicists coax superconductivity and more from quasicrystals

In research that could jump-start interest into an enigmatic class of materials known as quasicrystals, MIT scientists and colleagues have discovered a relatively simple, flexible way to create new atomically thin versions that can be tuned for important phenomena. In work reported in a recent issue of Nature, they describe doing just that to make […]

Study suggests energy-efficient route to capturing and converting CO2

In the race to draw down greenhouse gas emissions around the world, scientists at MIT are looking to carbon-capture technologies to decarbonize the most stubborn industrial emitters. Steel, cement, and chemical manufacturing are especially difficult industries to decarbonize, as carbon and fossil fuels are inherent ingredients in their production. Technologies that can capture carbon emissions […]
