Hemispherical array of ultrasound transducers lifts objects off reflective surfaces. Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a […]

The experimental setup and test site at Store Glacier, Greenland. Researchers conceptualized a battery-powered receiver with an antenna placed on the ice that can measure ice thickness using the sun’s radio waves.

ANIMATION Year after year, the explosive growth of computing power relies on manufacturers’ ability to fit more and more components into the same amount of space on a silicon chip. That progress, however, is now approaching the limits of the laws of physics, and new materials are being explored as […]

When Ben Calhoun and Dave Wentzloff co-founded Everactive in 2012, analysts and tech […]

This prototype device creates a warm white light without the blue hues that can cause health problems. Credit: Jakoah Brgoch To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which […]

Researchers have developed a data transfer system that pairs high-frequency silicon chips with a polymer cable as thin a strand of hair. Credit: Courtesy of the researchers, edited by MIT News The advance could improve energy efficiency of data centers and lighten the load for electronics-rich vehicles. Researchers have developed […]

Artist’s representation of the nanoscopic structure of a new ferroelectric material developed by MIT researchers and colleagues. Blue and gold dots represent the boron and nitride atoms in two atomically thin sheets of boron nitride. Between these sheets are two layers of graphene; the whitish/blue dots represent carbon atoms. The […]

STEM (scanning transmission electron microscopy) image of a one-dimensional array of F4TCNQ molecules (yellow-orange) on a gate-tunable graphene device. Credit: Berkeley Lab Removing one charged molecule from a one-dimensional array causes the others to alternately turn ‘on’ or ‘off,’ paving the way for information transfer in tiny circuits. Small electronic […]

Nanosatellite thrusters that emit a stream of pure ions are the first of their kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. A stainless steel version (top) works better overall but is much more expensive to produce. MIT researchers […]

Schematic of light-induced formation of Weyl points in a Dirac material of ZrTe5. Jigang Wang and collaborators report how coherently twisted lattice motion by laser pulses, i.e., a phononic switch, can control the crystal inversion symmetry and photogenerate giant low dissipation current with an exceptional ballistic transport protected by induced […]
