Newly discovered phenomenon could affect materials in batteries and water-splitting devices.
When one type of an oxide structure called perovskite is exposed to both water vapor and streams of electrons, it exhibits behavior that researchers had never anticipated: The material gives off oxygen and begins oscillating, almost resembling a living, breathing organism. The phenomenon was ...
Technique for calculating elasticity could aid design of new materials
All polymers have a distinctive degree of elasticity — how much they will stretch when a force is applied. However, for the past 100 years, polymer scientists have been stymied in their efforts to predict polymers’ elasticity, because the materials usually have structural flaws at the molecular ...
Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that "remember" their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures -- from small coils and multimaterial flowers, ...
Using electricity rather than heat can reduce both energy costs and greenhouse gas emissions.
The MIT researchers were trying to develop a new battery, but it didn’t work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony — and potentially a new way of smelting other metals, as well. The ...
New lithium metal batteries could make smartphones, drones, and electric cars last twice as long.
An MIT spinout is preparing to commercialize a novel rechargable lithium metal battery that offers double the energy capacity of the lithium ion batteries that power many of today’s consumer electronics. Founded in 2012 by MIT alumnus and former postdoc Qichao Hu ’07, SolidEnergy Systems has ...
Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight. But such batteries have some pretty serious drawbacks: They waste much of the injected ...
In the world of quantum, infinitesimally small particles, weird and often logic-defying behaviors abound. Perhaps the strangest of these is the idea of superposition, in which objects can exist simultaneously in two or more seemingly counterintuitive states. For example, according to the laws of ...
Method uses readily available tools to quickly determine materials’ properties.
Researchers at MIT and elsewhere have developed a new combination of methods that can provide detailed information about the microstructure of polycrystalline metals. Such materials — composed of a random matrix of multiple small crystals rather than one single large crystal — are widely used for ...
Inexpensive sensors could be worn by soldiers to detect hazardous chemical agents
MIT researchers have developed low-cost chemical sensors, made from chemically altered carbon nanotubes, that enable smartphones or other wireless devices to detect trace amounts of toxic gases. Using the sensors, the researchers hope to design lightweight, inexpensive radio-frequency ...
September ozone hole has shrunk by 4 million square kilometers since 2000
Scientists at MIT and elsewhere have identified the "first fingerprints of healing" of the Antarctic ozone layer. The team found that the September ozone hole has shrunk by more than 4 million square kilometers -- about half the area of the contiguous United States -- since 2000, when ozone ...
