The discovery could help researchers engineer exotic electrical states such as unconventional superconductivity. |
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 electrical states depending on the voltage, or current of electrons, that is applied.

Overall technique could be applied to other materials |
|
MIT physicists and colleagues have engineered a new property into a well-known family of semiconductors by manipulating ultrathin sheets of the materials only a few atomic layers thick.
The work is important because the new materials themselves could have interesting applications in computing and more. In addition, the overall approach is generic and can be applied to other pre-existing materials, expanding their potential applications as well.

|
Honored for Contributions to the Science of Light |
|
Three principal investigators from the Materials Research Laboratory (MRL) have been named 2022 Fellows of Optica, the leading organization for scientists and engineers interested in the science of light.
Anuradha Murthy Agarwal, Juejun Hu, and Lionel Kimerling are among 106 new members elected by their peers for serving with distinction in the advancement of optics and photonics. The election process is highly competitive because Fellows can account for no more than 10 percent of the total membership.

Faculty leaders detail promising technologies, materials, and methods that could help unlock a low-carbon future in sectors where emissions are hardest to cut. |
|
The industrial sector is the backbone of today’s global economy, yet its activities are among the most energy-intensive and the toughest to decarbonize. Efforts to reach net-zero targets and avert runaway climate change will not succeed without new solutions for replacing sources of carbon emissions with low-carbon alternatives and developing scalable nonemitting applications of hydrocarbons.
In conversations prepared for MIT News, faculty from three of the teams with projects in the competition’s “Decarbonizing complex industries and processes” category discuss strategies for achieving impact in hard-to-abate sectors, from long-distance transportation and building construction to textile manufacturing and chemical refining. The other Climate Grand Challenges research themes include using data and science to forecast climate-related risk, building equity and fairness into climate solutions, and removing, managing, and storing greenhouse gases. The following responses have been edited for length and clarity.
