A Bi-Functional Electrolyte Design for Long Lasting Batteries
April 24, 2014 — An innovative design of a bi-functional electrolyte defies the theoretical maximum energy capacity of conventional lithium carbon fluoride (Li-CFx) batteries. This novel design has the potential of enabling the creation of long lasting batteries for implantable medical devices, wearable electronics and other applications.
Light-emitting diodes from monolayer WSe2 p-n junctions
April 24, 2014 — Light emitting diodes (LEDs) with improved efficiency have been realized using monolayers of WSe2 carefully cleaved from high-quality bulk single crystals. This new development has the potential for applications in novel optoelectronic devices, such as on-chip lasers.
Phonon localization drives nanoregions in a relaxor ferroelectric
April 11, 2014 — Neutron scattering measurements reveal that phonon localization drives the generation of polar nanoregions (PNRs) in a relaxor ferroelectric. PNRs facilitate the ability of relaxor ferroelectrics to convert between electrical and mechanical forms of energy, which is used in applications ranging from medical ultrasound to military sonar devices.
