MIT Circuit Design Simplifies Superconducting Circuits

MIT researchers present a new circuit design that could unlock the power of experimental superconducting computer chips and make simple superconducting devices much cheaper to manufacture. Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing […]

Silicon Qubits Are Ready for Large Scale Quantum Computers

Two newly published studies show that the accuracy and lifetime of silicon qubits are now suitable for large-scale quantum computers. A dramatic increase in the amount of time data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers. The silicon chip revolutionized […]

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Researchers Control Nanoparticles with Light and Magnets

A team of researchers has developed particles that can glow with color-coded light and be manipulated with magnets, improving the likelihood of tracking the position of the nanoparticles as they move within the body or inside a cell. A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, […]

New Mechanism of Photoconduction Could Lead to Next Generation Excitonic Devices

Physicists at MIT have discovered that shining light on a single layer of molybdenum disulfide (MoS2) can make the material less conductive. It’s a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered that […]

Nanoparticles Break the Symmetry of Light

Using an unusual kind of coupling between spin and the direction of propagation, physicists from the Vienna University of Technology are able to select the direction that nanoparticles can emit light into ultra-thin glass fibers. How can a beam of light tell the difference between left and right? At the Vienna University of Technology (TU […]

New Technology Enables Fast and Cheap Nanomanufacturing

A newly published study from MIT details how arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply. Luis Fernando Velásquez-García’s group at MIT’s Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: […]

Crumpled Graphene Forms Stretchable Supercapacitors

New research from engineers at MIT details how two-dimensional carbon “paper” can form stretchable supercapacitors to power flexible electronic devices. When someone crumples a sheet of paper, that usually means it’s about to be thrown away. But researchers have now found that crumpling a piece of graphene “paper” — a material formed by bonding together […]

Scientists Addvance Solar Power with New Gold Nanocluster Technology

Using approximately 10,000 times less gold than in previous studies, researchers from Western University improve solar power performance with new “gold nanocluster” technology. Scientists at Western University have discovered that a small molecule created with just 144 atoms of gold can increase solar cell performance by more than 10 per cent. These findings, published recently […]
