From medicine to space travel, Chuck Hoberman’s shape-shifting is expanding scientific research. A sneak peek at Hoberman’s latest prototype: a sphere that transforms shape, size and color by turning itself inside out.

Researchers have discovered a way to transform the electronic properties of nanoscale needles of diamond. Credit: MIT News Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a new theoretical model. Long known as the hardest of all natural materials, diamonds are also exceptional thermal […]

Stacking monolayer and bilayer graphene sheets with a twist leads to new collective electronic states, including a rare form of magnetism. Credit: Columbia University Twisting a monolayer and a bilayer sheet of graphene into a three-layer structure leads to new quantum mechanical states. Since the discovery of graphene more than 15 years […]

Injecting calcium into graphene creates a superconductor, but where does the calcium actually end up? Credit: FLEET ‘Floating’ Graphene on a Bed of Calcium Atoms Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go? Adding calcium to a composite graphene-substrate structure creates a high transition-temperature (Tc) superconductor. […]

Researchers led by Katja Nowack, assistant professor of physics, created this micron-scale Hall-effect sensor by sandwiching graphene between sheets of hexagonal boron nitride, resulting in a device that operates over a greater temperature range than previous Hall sensors.

Credit: MIPT While 100-nanometer thin films of vanadium dioxide (VO2) do not normally conduct electricity, their resistance drops up to 100,000 times when slightly heated. This may happen under applied voltage, for example. That property is used to create high-speed switchable devices and sensors for direct current or alternating signal in […]

Researchers have developed electronic artificial skin that reacts to pain just like real skin, opening the way to better prosthetics, smarter robotics and […]

Scientists have developed a method to 3D print structures using local soil. Credit: Aayushi Bajpayee The construction industry is currently facing two major challenges: the demand for sustainable infrastructure and the need to repair deteriorating buildings, bridges, and roads. While concrete is the material of choice for many construction projects, […]
