Research Bits: Nov. 1


Atomic-level rare earth manipulation Scientists from Ohio University, Argonne National Laboratory, and the University of Illinois at Chicago have rotated a single, charged rare earth molecule on a metal surface without changing the charge. The team used scanning tunneling microscopy (STM) system to rotate a positively charged Europium base molecule with negatively charged counterions as a p... » read more

Characterizing 2D borophene Researchers at Rice and Northwestern universities collaborated on a method to view the polymorphs of 2D borophene crystals, providing insights into the lattice configurations of the two-dimensional material. Boris Yakobson, a materials physicist at Rice’s Brown School of Engineering, and materials scientist Mark Hersam of Northwestern led a team that not only d... » read more

Power/Performance Bits: Dec. 18


Solar storage Engineers at MIT, Georgia Institute of Technology, and the National Renewable Energy Laboratory designed a system to store renewable energy in vast amounts and deliver it back to the grid when power generation is low. The system stores excess electricity from solar or wind installations as heat using tanks of white-hot molten silicon, and then converts the light from the glowi... » read more

Lithium-air battery Researchers at the University of Illinois at Chicago and Argonne National Laboratory designed a new lithium-air battery that works in a natural air environment and still functioned after 750 charge/discharge cycles, a record for this battery type. In theory, lithium-air batteries work by combining lithium present in the anode with oxygen from the air to produce lithium p... » read more

Power/Performance Bits: Aug. 2


From sun to hydrocarbon fuel Researchers at the University of Illinois at Chicago have engineered a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device converts atmosph... » read more

Contender emerges for 3D IC semiconductor material While silicon has few serious competitors as the material of choice in the electronics industry, transistors cannot keep shrinking to meet the needs of next-gen devices given the significant physical limitations of energy consumption and heat dissipation. To address this, researchers at Harvard University have achieved a reversible change in e... » read more

Cooper Pairs Researchers at the University of Illinois at Chicago, Cornell University and Brookhaven National Laboratory say they have unlocked what they’re calling quantum glue—the underlying basis for creating energy conduits without current loss. In superconductors, electrical resistance vanishes below a critical temperature and conduction electrons form ordered pairs, known as Coop... » read more
