Transistors are tiny switches that form the bedrock of modern computing; billions of them route electrical signals around inside a smartphone, for instance. Quantum computers will need analogous hardware to manipulate quantum information. But the design constraints for this new...
For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3D printing. The innovative approach might one day be used with an endoscope...
Correlation between cryo-transmission electron microscope (TEM) images and the crystal structure. (l) TEM image showing three colliding clusters. The scale bar is 10 nm. (r) Relative positions of molecules derived from the X-ray diffraction crystal structure are overlaid (brown)...
Credit: Georgia Institute of Technology Researchers at Georgia Institute of Technology have developed a new process for treating metal surfaces that has the potential to improve efficiency in piston engines and a range of other equipment. The method improves the ability...
In the Standard Model of particle physics, there is almost no difference between matter and antimatter. But there is an abundance of evidence that our observable universe is made up only of matter -- if there was any antimatter,...
At Karlsruhe Institute of Technology (KIT), physicist Professor Thomas Schimmel and his team have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the...
The research team was able to make the azo-LCN film ascend a 15° incline. Credit: Wie, J. J. et al. Photomotility of polymers. Nat. Commun. 7, 13260 doi: 10.1038/ncomms13260 (2016). One of the impediments to developing miniaturized, "squishy" robots is...
The X-ray crystal structure of a 192-atom-loop molecular 819 knot featuring iron ions (shown in purple), oxygen atoms (red), nitrogen atoms (dark blue), carbon atoms (shown in metallic grey, with one of the building blocks shown in light blue)...
This first version of a new layered perovskite solar cell already achieves an efficiency of more than 20 percent, rivaling many commercial solar cells. Flexible and easy to make, it can produce more than half a volt of electricity....
