Rensselaer Polytechnic Institute has been awarded $2.2 million in funding from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) to develop innovative ion conduction materials for next-generation renewable energy conversion and storage technology.
By doping a thermoelectric material with minute amounts of sulfur, a team of researchers has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture. This approach profoundly alters the electronic band structure of the material – bismuth telluride selenide — improving the so-called “figure of merit,” a ranking of a material’s performance that determines efficiency in applications and opening the door to advanced applications of thermoelectric materials to harvest waste heat from power plants to computer chips.

Nanophotonics expert and physics professor Shawn-Yu Lin will receive a 2016 IEEE award for his role in discovering the darkest nano-material on Earth.
In a collaborative and multidisciplinary study, scientists develop methods to explore phosphorene and its properties. Phosphorene, discovered in 2014, is related to the two-dimensional graphene and has been established to have numerous photonic applications. The majority of these properties, however, is its capacity for anisotropic electron conduction. This means that its electron conduction property changes depending on the crystal orientation.
Researchers have developed a new method to quickly and accurately determine that of phosphorene, a promising new material with potential application in semiconductor transistors.
A new method to control the activity of neurons in mice, devised by scientists at Rensselaer Polytechnic Institute (RPI) and Rockefeller University, uses magnetic forces to remotely control the flow of ions into specifically targeted cells.
Plasmons, quasiparticles arising from the collective motion of electrons on the surface of a metal, can strongly modify the behavior of nearby light, and could be instrumental in building some of the key components of a quantum circuit.
In research published in the journal Science, researchers at Rensselaer have developed a new layered structure for graphene that transforms high-quality 2-D graphene sheets into its 3-D form while maintaining its thermal and electrical properties and mechanical strength.
