Researchers develop a paper-thin loudspeaker

MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source. This thin-film loudspeaker produces sound with minimal distortion while using a fraction of the energy required by a traditional loudspeaker. The hand-sized loudspeaker the team demonstrated, which weighs about as much as a dime, can generate high-quality sound […]

Providing hands-on photonics education across Massachusetts

Photonics — the science of guiding and manipulating light — enables applications ranging from telecommunications, artificial intelligence, and quantum computing to medical imaging, lidar, and augmented reality displays. But despite the importance of this growing field, the nation faces a shortage of photonics and electronics technicians and engineers. The Lab for Education and Application Prototypes […]

MIT scientists develop low-cost, high-precision fabrication method for thin mirrors and silicon wafers

Technologies that depend on lightweight, high-precision optical systems, like space telescopes, X-ray mirrors, and display panels, have developed significantly over the past several decades, but more advanced progress has been limited by seemingly simple challenges. For example, the surfaces of mirrors and plates with microstructures that are necessary in these optical systems can be distorted […]

MIT.nano Immersion Lab Gaming Program awards third annual seed grants

MIT.nano has announced its next round of seed grants to support hardware and software research related to sensors, 3D/4D interaction and analysis, augmented and virtual reality (AR/VR), and gaming. The grants are awarded through the MIT.nano Immersion Lab Gaming Program, a four-year collaboration between MIT.nano and NCSOFT, a digital entertainment company and founding member of […]

MIT to name Building 12, home of MIT.nano, in honor of Lisa Su

Building 12, the home of MIT.nano, will soon be named in honor of Lisa T. Su ’90, SM ’91, PhD ’94, chief executive officer and chair of the Board of Directors of AMD. Su is the first MIT alumna to make a gift for a building that will bear her own name.  Lisa Su led […]

Featured video: L. Rafael Reif on the power of education

MIT President L. Rafael Reif recently joined Raúl Rodríguez, associate vice president of internationalization at Tecnológico de Monterrey, for a wide-ranging fireside chat about the power of education and its impact in addressing global issues, even more so in a post pandemic world.  “When I was younger, my parents used to always tell me and my […]

Physicists find direct evidence of strong electron correlation in a 2D material for the first time

In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These materials, which include “magic-angle” graphene and other synthesized two-dimensional materials, can shift […]

How to clean solar panels without water

Solar power is expected to reach 10 percent of global power generation by the year 2030, and much of that is likely to be located in desert areas, where sunlight is abundant. But the accumulation of dust on solar panels or mirrors is already a significant issue — it can reduce the output of photovoltaic […]

Toward batteries that pack twice as much energy per pound

In the endless quest to pack more energy into batteries without increasing their weight or volume, one especially promising technology is the solid-state battery. In these batteries, the usual liquid electrolyte that carries charges back and forth between the electrodes is replaced with a solid electrolyte layer. Such batteries could potentially not only deliver twice […]

Gina Raimondo: “Let’s get back to the business of building microchips in America”

The global semiconductor shortage, a major driver of ballooning U.S. inflation, is as much a national security issue as an economic issue, U.S. Secretary of Commerce Gina Raimondo said during a recent visit to MIT. Speaking at MIT.nano, a shared 214,000-square-foot research center for nanoscale science and engineering located in the heart of campus, Raimondo […]

More sensitive X-ray imaging

Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They’re also used for night-vision systems and for research, such as in particle detectors or electron microscopes. Researchers at […]

Size matters in particle treatments of traumatic injuries

Traumatic injuries are the leading cause of death in the U.S. among people 45 and under, and such injuries account for more than 3 million deaths per year worldwide. To reduce the death toll of such injuries, many researchers are working on injectable nanoparticles that can home in on the site of an internal injury […]

Solar-powered system offers a route to inexpensive desalination

An estimated two-thirds of humanity is affected by shortages of water, and many such areas in the developing world also face a lack of dependable electricity. Widespread research efforts have thus focused on ways to desalinate seawater or brackish water using just solar heat. Many such efforts have run into problems with fouling of equipment […]
