Energy Efficiency
Flexible lithium batteries have been incorporated into dental braces as part of efforts to increase the efficiency of corrective orthodontics.
Los Alamos National Laboratory Chemist Jaehoon Lim works on an apparatus that synthesizes quantum dots along with Los Alamos researcher Young-Shin Park (also with the University of New Mexico Center for High-Technology Materials). In a paper published in Nature Nanotechnology, Los Alamos colleagues Kaifeng Wu and Victor Klimov worked with Lim and Park to demonstrate that negatively charged quantum dots show promise for low-power laser applications or quantum dot laser diodes.
Anders Nordelöf believes that the much-discussed environmental issues associated with electric cars should be taken seriously, but thinks that more focus is needed on solving the issues -- not on discussing whether electric cars should exist at all. Here, life cycle assessment is an important tool.
This image shows an energy diagram of the WSe2-MoSe2 device. When a photon (1) strikes the WSe2 layer, it knocks loose an electron (2), freeing it to conduct through the WSe2 (3). At the junction between the two materials, the electron drops down into MoSe2 (4). The energy given off in the drop catapults a second electron from the WSe2 (5) into the MoSe2 (6), where both electrons are free to move and generate electricity.

This is the direct conversion of CO2 and CH4 into liquid fuels.
Artist's impression of the role of a quantum observer: depending on where the observer is positioned, and what part of the figure is seen, the water will be seen to flow differently.
These are crystal structures of crystalline solvates.
Scanning electron microscope images show an anode of asphalt, graphene nanoribbons and lithium at left and the same material without lithium at right. The material was developed at Rice University and shows promise for high-capacity lithium batteries that charge up to 20 times faster than commercial lithium-ion batteries.
Sorghum is a unique crop in that most varieties are both drought and heat tolerant. The development of a low input, environmentally safe and highly productive sorghum germplasm will help establish a lignocellulosic energy economy that can provide jobs to rural communities, ensure energy security and benefit the environment.
