Pablo Jarillo-Herrero receives the Lise Meitner Distinguished Lecture and Medal - MIT - Carbon (Nov 06, 2020) |
|
Nov 06, 2020 · Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics, was awarded the Lise Meitner Distinguished Lecture and Medal, for his groundbreaking work on “twistronics,” a technique that adjusts the electronic properties of graphene by rotating adjacent layers of the material.
His breakthrough research in twisted bilayer graphene research discovered unique electrical properties with the potential to create innovative superconducting materials and novel quantum devices for advanced quantum sensing, photonics, and computing applications.
The medal, sponsored by the Royal Swedish Academy of Sciences through its Nobel Committee for Physics, recognizes the work by ... Read more ...

Antarctic sea ice may not cap carbon emissions as much as previously thought - MIT - Carbon (Oct 01, 2020) |
|
Oct 01, 2020 · The Southern Ocean surrounding Antarctica is a region where many of the world’s carbon-rich deep waters can rise back up to the surface. Scientists have thought that the vast swaths of sea ice around Antarctica can act as a lid for upwelling carbon, preventing the gas from breaking through the ocean’s surface and returning to the atmosphere.
However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global carbon cycle as scientists had suspected.
In a study published in the August issue of the journal Global Biogeochemical Cycles, the team has found that indeed, sea ice in the Southern ... Read more ...

Peatland drainage in Southeast Asia adds to climate change - MIT - Carbon (Jun 04, 2020) |
|
Jun 04, 2020 · Media can only be downloaded from the desktop version of this website.
In less than three decades, most of Southeast Asia’s peatlands have been wholly or partially deforested, drained, and dried out. This has released carbon that accumulated over thousands of years from dead plant matter, and has led to rampant wildfires that spew air pollution and greenhouse gases into the atmosphere.
The startling prevalence of such rapid destruction of the peatlands, and their resulting subsidence, is revealed in a new satellite-based study conducted by researchers at MIT and in Singapore and Oregon. The research was published today in the journal Nature Geoscience, in a paper by ... Read more ...

Researchers map tiny twists in "magic-angle" graphene | MIT News - MIT - Carbon (May 07, 2020) |
|
May 07, 2020 · Media can only be downloaded from the desktop version of this website.
Made of a single layer of carbon atoms linked in a hexagonal honeycomb pattern, graphene's structure is simple and seemingly delicate. Since its discovery in 2004, scientists have found that graphene is in fact exceptionally strong. And although graphene is not a metal, it conducts electricity at ultrahigh speeds, better than most metals.
In 2018, MIT scientists led by Pablo Jarillo-Herrero and Yuan Cao discovered that when two sheets of graphene are stacked together at a slightly offset "magic" angle, the new "twisted" graphene structure can become either an insulator, completely blocking electricity ... Read more ...

How growth of the scientific enterprise influenced a century of quantum physics | MIT News - MIT - Carbon (Apr 29, 2020) |
|
Apr 29, 2020 · Austrian quantum theorist Erwin Schrödinger first used the term "entanglement," in 1935, to describe the mind-bending phenomenon in which the actions of two distant particles are bound up with each other. Entanglement was the kind of thing that could keep Schrödinger awake at night; like his friend Albert Einstein, he thought it cast doubt on quantum mechanics as a viable description of the world. How could it be real?
And yet, evidence keeps accumulating that entanglement exists. Two years ago MIT Professor David Kaiser and an international team used lasers, single-photon detectors, atomic clocks, and huge telescopes collecting light that had been released by distant ... Read more ...

Understanding how fluids heat or cool surfaces | MIT News - MIT - Carbon (Apr 28, 2020) |
|
Apr 28, 2020 · Whether it's water flowing across a condenser plate in an industrial plant, or air whooshing through heating and cooling ducts, the flow of fluid across flat surfaces is a phenomenon at the heart of many of the processes of modern life. Yet, aspects of this process have been poorly understood, and some have been taught incorrectly to generations of engineering students, a new analysis shows.
The study examined several decades of published research and analysis on fluid flows. It found that, while most undergraduate textbooks and classroom instruction in heat transfer describe such flow as having two different zones separated by an abrupt transition, in fact there are three ...

Dirty carbon reveals a sophisticated side | MIT News - MIT - Carbon (Apr 27, 2020) |

Tar, the everyday material that seals seams in our roofs and driveways, has an unexpected and unappreciated complexity, according to an MIT research team: It might someday be useful as a raw material for a variety of high-tech devices including energy storage systems, thermally active coatings, and electronic sensors.
And it's not just tar. Professor Jeffrey Grossman has a very different view of other fossil fuels as well. Rather than using these materials as cheap commodities to burn up, seal cracks with, or dispose of, he sees potential for a wide variety of applications that take advantage of the ... Read more ...

New model of the GI tract could speed drug development | MIT News - MIT - Carbon (Apr 27, 2020) |
|
Apr 27, 2020 · MIT engineers have devised a way to speed up the development of new drugs by rapidly testing how well they are absorbed in the small intestine. This approach could also be used to find new ways to improve the absorption of existing drugs so that they can be taken orally.
Developing drugs that can be easily absorbed in the gastrointestinal tract is a particular challenge for treating neglected tropical diseases, tuberculosis, and malaria, says Giovanni Traverso, an assistant professor of mechanical engineering at MIT and a gastroenterologist at Brigham and Women's Hospital.
"Many of the drugs that are being developed today for neglected tropical diseases are insoluble and ... Read more ...

Study analyzes contamination in drug manufacturing plants | MIT News - MIT - Carbon (Apr 27, 2020) |
|
Apr 27, 2020 · Over the past few decades, there have been a handful of incidents in which manufacturing processes for making protein drugs became contaminated with viruses at manufacturing plants. These were all discovered before the drugs reached patients, but many of the incidents led to costly cleanups and in one instance a drug shortage.
A new study from an MIT-led consortium has analyzed 18 of these incidents, most of which had not been publicly reported until now. The report offers insight into the most common sources of viral contamination and makes several recommendations to help companies avoid such incidents in the future.
While the study focused on biopharmaceuticals ... Read more ...
