New technique builds super-hard metals from nanoparticles

Posted by in category: nanotechnology

Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal’s grain structure—the microscopic crystalline domains that form a bulk piece of metal. Smaller grains make for harder metals.

Now, a group of Brown University researchers has found a way to customize metallic grain structures from the bottom up. In a paper published in the journal Chem, the researchers show a method for smashing individual nanoclusters together to form solid macro-scale hunks of solid metal. Mechanical testing of the metals manufactured using the technique showed that they were up to four times harder than naturally occurring metal structures.

“Hammering and other hardening methods are all top-down ways of altering , and it’s very hard to control the you end up with,” said Ou Chen, an assistant professor of chemistry at Brown and corresponding author of the new research. “What we’ve done is create nanoparticle building blocks that fuse together when you squeeze them. This way we can have uniform grain sizes that can be precisely tuned for enhanced properties.”

DARPA program seeks night-vision goggles as light and compact as glasses

Posted by in category: military

DARPA is starting a program to develop a new multispectral Enhanced Night Vision (ENVision) system for the military that replaces today’s heavy night-vision goggles with ones that are as light and compact as a pair of eyeglasses.

Night-vision devices were first developed before the Second World War, but only became practical in the 1960s. Since then, they have revolutionized warfare by effectively eliminating the cover of darkness as protection for a hostile force. Where once aircraft and ground troops were effectively nullified by the fall of night, pilots and soldiers can now operate as if it was high noon.

However, the technology is far from mature even after four or five development generations. The devices have become more sophisticated and sensitive, with the capability to see across more of the infrared spectrum as well as seeing heat signatures, but night-vision goggles remain bulky and heavy, with a field of vision that’s a third that of the naked eye.

Experts Warn Civil Rights Fallout from COVID Could be Far Worse Than the Pandemic Itself

Posted by in categories: biotech/medical, health, law

Ditto for Canada…


As US President Biden signs a national mask mandate into law, measures being imposed in the name of protecting public health could create a humanitarian crisis that sees Americans sued by the state and forced into detention camps for breaking pandemic protocols.

The very first executive order Joe Biden signed upon becoming the forty-sixth President of the United States was the national mask mandate he promised at the Democratic National Convention back in August. The order makes face coverings and social distancing mandatory on all federal property and a legal requisite for interstate commerce.

MIT develops method for lab-grown plants that eventually lead to alternatives to forestry and farming

Posted by in categories: food, materials

Researchers at[ MIT have developed a new method for growing plant tissues in a lab](https://news.mit.edu/2021/lab-grown-plant-tissue-0120) — sort of like how companies and researchers are approaching lab-grown meat. The process would be able to produce wood and fibre in a lab environment, and researchers have already demonstrated how it works in concept by growing simple structures using cells harvested from zinnia leaves.

The process would be able to produce wood and fibre in a lab environment, and researchers have already demonstrated how it works in concept by growing simple structures using cells harvested from zinnia leaves.

This work is still in its very early stages, but the potential applications of lab-grown plant material are significant, and include possibilities in both agriculture and in construction materials. While traditional agricultural is much less ecologically damaging when compared to animal farming, it can still have a significant impact and cost, and it takes a lot of resources to maintain. Not to mention that even small environmental changes can have a significant effect on crop yield.

New high-tech spray-on coating can make buildings, cars, and even spaceships cooler

Posted by in categories: climatology, space travel

This coating might prove useful for several sorts of applications.


Managing temperatures in particularly hot and sunny climates can be very difficult even today. You can use air conditioning to displace the heat from inside structures and vehicles, but it sucks up so much power and can generate pollution that ultimately makes temperature problems even worse.

China debuts train prototype that can hit speeds of 620 kilometers per hour

Posted by in categories: energy, transportation

China has revealed a prototype for a new high-speed Maglev train that is capable of reaching speeds of 620 kilometers (385 miles) per hour.

The train runs on high-temperature superconducting (HTS) power that makes it look as if the train is floating along the magnetized tracks.

The sleek 21-meter-long (69 feet) prototype was unveiled to media in the city of Chengdu, Sichuan Province, on January 13. In addition, university researchers constructed 165 meters (541 feet) of track to demonstrate how the train would look and feel in transit, according to state-run Xinhua News.

Groundbreaking New Laser System Cuts Through Earth’s Atmosphere Like It’s Nothing

Posted by in category: futurism

To artists and romantics, the twinkling of stars is visual poetry; a dance of distant light as it twists and bends through a turbulent ocean of air above our heads.

Not everybody is so enamoured with our atmosphere’s distortions. To many scientists and engineers, a great deal of research and ground-to-satellite communication would be a whole lot easier if the air simply wasn’t there.

Losing our planet’s protective bubble of gases isn’t exactly a popular option. But Australian and French researchers have teamed up to design the next best thing – a system that guides light through the tempestuous currents of rippling air with the flick of a mirror.
