Lindsay explored the interactions between a protein, called an integrin (alphaVbeta3), and its target, called a ligand (RGDfC). Lindsay's team was able to manufacture a nanodevice to more finely control a series of experiments with a carefully sized gap to control the protein, an electrode holding the ligand in position, and control the amount of voltage that can be applied to it.

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 is the reduction of CO2.
Two floating wind turbines being prepared to sail to Hywind Scotland Pilot Park off the coast of Aberdeenshire.
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.
The Italian President congratulate Jens Nielsen at an official ceremony in the Quirinal Palace in Rome with winning an Eni award for his research on the production of fuels from renewables.
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.
The blue and red cones show the energy and momentum of surface electrons in a 3D topological insulator. The spin structure is shown in the blue and red arrows at the top and bottom, respectively. Light promotes electrons from the blue cone into the red cone, with the spin direction flipping. The orderly spinning leads to the chiral spin mode observed in this study.
This is a schematic representation of Ti4O7 (a) and γ-Ti3O5 (b).
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.
