One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or ‘doped,’ with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.
A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a safe, clean and abundant source of energy for generating electricity from power plants around the world.
A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.
Researchers have determined how electrocatalysts can convert carbon dioxide to carbon monoxide using water and electricity. The discovery can lead to the development of efficient electrocatalysts for large scale production of synthesis gas — a mixture of carbon monoxide and hydrogen.
LG is opening Europe’s largest factory for building lithium-ion batteries destined for use in electric cars, the company announced. Its LG Chem division is going to open the doors for the facility in 2019 in Poland near Wroclaw, per Reuters, and the facility will be able to supply as many as 100,000 EV batteries per year beginning next year.

Toyota has hydrogen fuel cell transport trucks that generate no local emissions, and that have 670 horsepower and an 80,000-pound total weight capacity. The powertrain includes two of Toyota’s Mirai fuel cells, and a 12kWh battery charged by the cells. Toyota is now running a concept version of the truck along pilot routes that run around 200 miles per day, moving goods between depots in… Read More
The same electrostatic charge that can make hair stand on end and attach balloons to clothing could be an efficient way to drive atomically thin electronic memory devices of the future, according to a new study. Scientists have found a way to reversibly change the atomic structure of a 2-D material by injecting it with electrons. The process uses far less energy than current methods for changing the configuration of a material’s structure.
At Nvidia’s GTC Europe conference today, one of the company’s partners detailed plans to bring an autonomous delivery fleet to operating status starting in 2018. Deutsche Post DHL Group wants to put trucks on the road in partnership with auto supplier ZF by that time frame, using electric light transport vehicles equipped with ZF’s Nvidia-based ProAI self-driving system.… Read More
Chemically stabilizing atomically flat materials improves their potential for commercial application, report scientists.
Puerto Rico’s power grid has been practically demolished in the wake of hurricane Maria. It now has a once in a lifetime opportunity to rebuild and the island’s governor Ricardo Rossello wants to have a chat with Elon Musk about his recent offer to use Tesla batteries and solar power for the the job.
