Experiments into amorphous carbon monolayer lend new evidence to physics debate

Jan. 8, 2020—Plastic, glass and gels, also known as bulk amorphous materials, are everyday objects to all of us. But for researchers, these materials have long been scientific enigmas – specifically when it comes to their atomic makeup, which lacks the strict ordered structure of crystals found in most solids such as metals, diamonds and salts. Although...

Quantum mechanics work lets oil industry know promise of recovery experiments before they start

Sep. 28, 2018—Sokrates Pantelides (Joe Howell / Vanderbilt University) With their current approach, energy companies can extract about 35 percent of the oil in each well. Every 1 percent above that, compounded across thousands of wells, can mean billions of dollars in additional revenue for the companies and supply for consumers. Extra oil can be pushed out...

Multitasking monolayers lay groundwork for devices that can do two things at once

Jul. 25, 2017—Illustration of the triangular pattern formed by the two-dimensional material chalcogenide that allows the creation of dual-function devices. (Yu-Yang Zhang / Chinese Academy of Sciences) Two-dimensional materials that can multitask. That is the result of a new process that naturally produces patterned monolayers that can act as a base for creating a wide variety of...
