Prof. Long Ju and his colleagues observed the fractional quantum anomalous Hall effect (FQAHE) when five layers of graphene were sandwiched between sheets of boron nitride, reports Dan Garisto for Nature. The findings are, “capturing physicists’ imagination because they are fundamentally new discoveries about how electrons behave,” writes Garisto.
Writing for Science, Charlie Greenwood spotlights how MIT researchers are building upon their pioneering work twisting sheets of graphene together to create superconductors by using twisted graphene to develop working devices. “Many researchers are excited by the promise of exploring electronic devices without worrying about the constraints of chemistry,” writes Greenwood.
Writing for Quanta Magazine, David Freedman spotlights Prof. Pablo Jarillo-Herrero’s discovery that when twisted to a “magic” angle, graphene can act as a semiconductor. Freedman writes that the “discovery has given scientists a relatively simple platform for exploring exotic quantum effects.”
Prof. Pablo Jarillo-Herrero speaks with Gizmodo reporter Ryan Mandelbaum about his work showing that when twisted to the right angle, graphene can serve as an insulator or semiconductor. “This sort of field of ‘twistronics’ is something with great potential in terms of scientific discovery and intellectual interest,” Jarillo-Herrero explains.
Nature reporter Elizabeth Gibney spotlights Prof. Pablo Jarillo-Herrero’s discovery that graphene can act as a superconductor when twisted to a magic angle. “I haven’t seen this much excitement in the graphene field since its initial discovery,” said ChunNing Jeanie Lau, a professor at Ohio State University, of the impact of Jarillo-Herrero’s findings.
Prof. Pablo Jarillo-Herrero’s discovery that when graphene is rotated to a “magic angle” it can act as a high-temperature superconductor has been named the Physics World 2018 Breakthrough of the Year. Physics World reporter Hamish Johnston writes that the “discovery led to the development of ‘twistronics’, which is a new and very promising technique for adjusting the electronic properties of graphene.”
Researchers from MIT are using the brittle nature of graphene to mass produce cell-sized robots, writes David Grossman of Popular Mechanics. Called “syncells” or synthetic cells, the researchers hope they can be used in biomedical testing. “Inject hundreds into the bloodstreams and let the data fly back into sensors,” explains Grossman.
IEEE Spectrum reporter Mark Anderson highlights how Prof. Jeehwan Kim’s research group has developed techniques to produce ultrathin semiconducting films and harvest the materials necessary to manufacture 2-D electronics. Anderson explains that the group’s advances could make possible such innovations as high-efficiency solar cells attached to a car’s exterior and low-power, long-lasting wearable devices.

MIT researchers have discovered that arranging two stacked layers of graphene at a slight angle makes the material a superconductor, writes Elizabeth Gibney for Nature. After discovering that the graphene had the ability to conduct electrons, researchers applied “a small electric field to feed just a few extra charge carriers into the system, and it became a superconductor.”
IEEE Spectrum reporter Dexter Johnson writes that MIT researchers have developed a technique for producing cheaper semiconductor wafers using graphene. The method could “make the use of exotic semiconductors more accessible to industries by preparing semiconductor thin films without the high cost of using bulk wafers.”
MIT researchers have created a new strong, yet lightweight material by using a 3-D printer to fuse flakes of graphene into a sponge-like object, reports Nick Kwek for BBC News. “The newfangled product could be used in the construction of airplanes or buildings,” says Kwek.
MIT researchers have used computer models to turn flakes of graphene into 3-D structures, creating one of lightest, strongest materials, writes Nicola Davison for CNN. "Once they combine and fuse together, all the flakes contribute to the strength of the overall structure," research scientist Zhao Qin explains.
Researchers at MIT have fused flakes of graphene into a sponge-like shape, creating one of the strongest lightweight materials, writes James Temperton for Wired. Flakes of graphene were compressed using heat and pressure, then 3-D printers were used to create a “strong, stable structure similar to some corals” for stress tests.
MIT researchers have developed a new ultra-light material that is ten times stronger than steel, reports Tia Ghose for CBS News. Ghose explains that in the future, the material could potentially be used to build bridges, “which would be ultrastrong, lightweight, and insulated against heat and cold because of all the myriad air pockets in the material.”
