Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material on top of it. Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing.
Physicists at the University of Arkansas have discovered a unifying framework in the dipolar patterns of two-dimensional ferroelectrics, a finding which could help advance the development of high-density information coding systems in computers and other electronics. Ferroelectric films are atomically thin materials that hold promise for dense information storage at the nanoscale.

Scientists at Rice University have extended their technique to produce graphene in a flash to tailor the properties of other 2D materials. The scientists have successfully “flashed” bulk amounts of 2D dichalcogenides, changing them from semiconductors to metallics. Such materials are valuable for electronics, catalysis, and as lubricants.

Researchers at Oregon State University have developed a battery anode based on a new nanostructured alloy that could revolutionize the way energy storage devices are designed and manufactured. The zinc- and manganese-based alloy further opens the door to replacing solvents commonly used in battery electrolytes with seawater, which is safer, inexpensive, and abundant.

Researchers at Lawrence Livermore National Laboratory have discovered that carbon nanotube membrane pores could enable ultra-rapid dialysis processes that would greatly reduce treatment time for hemodialysis patients. The researchers found that carbon nanotube pores might provide a solution to the permeability vs. selectivity tradeoff, which is well-known for synthetic membranes. When using a concentration gradient as a driving force, small ions were found to diffuse through these tiny pores more than an order of magnitude faster than when moving in bulk solution.

Chemists at Emory University, the U.S. Department of Energy’s Argonne National Laboratory, and Paul Scherrer Institut in Switzerland have developed a nanomaterial that can be triggered to shape-shift – from flat sheets to tubes and back to sheets again – in a controllable way. The nanomaterial holds potential for a range of biomedical applications, from controlled-release drug delivery to tissue engineering.
