Asteroid impacts create diamond materials with exceptionally complex structures

Posted by in categories: asteroid/comet impacts, energy, engineering, existential risks

Shockwaves caused by asteroids colliding with Earth create materials with a range of complex carbon structures, which could be used for advancing future engineering applications, according to an international study led by UCL and Hungarian scientists.

Published today in Proceedings of the National Academy of Sciences, the team of researchers has found that formed during a high-energy shock wave from an around 50,000 years ago have unique and exceptional properties, caused by the short-term high temperatures and extreme pressure.

The researchers say that these structures can be targeted for advanced mechanical and electronic applications, giving us the ability to design materials that are not only ultra-hard but also malleable with tunable electronic properties.

Lockheed Martin gets $59 million order for Stryker cyber and electronic warfare suite

Posted by in categories: energy, engineering, military, space

Lockheed Martin has been busy this year. In April of 2022, the Defense Advanced Research Projects Agency (DARPA) and its U.S. Air Force partner announced that they had completed a free flight test of the Lockheed Martin version of the Hypersonic Air-breathing Weapon Concept (HAWC).

Then just last month, the U.S. Department of Defense (DoD) awarded the company a contract to construct the nation’s first megawatt-scale long-duration energy storage system. Under the direction of the U.S. Army Engineer Research and Development Center’s (ERDC) Construction Engineering Research Laboratory (CERL), the new system, called “GridStar Flow,” will be set up at Fort Carson, Colorado.

In the same time frame, General Motors and the firm announced their plans to produce a series of electric moon rovers for future commercial space missions. The companies said they plan aim to test the batteries developed by GM, in space later this year. They also set the ambitious goal of testing a prototype vehicle on the moon by 2025.

MIT Professor Wins European Inventor Award for Liquid Metal Batteries

Posted by in categories: chemistry, energy, sustainability

For his work on liquid metal batteries that could enable the long-term storage of renewable energy, MIT Professor Donald Sadoway has won the 2022 European Inventor Award, in the category for Non-European Patent Office Countries.

Sadoway is a longtime supporter and friend of MIT’s Materials Research Laboratory and is the John F. Elliott Professor of Materials Chemistry in MIT’s Department of Materials Science and Engineering.

“By enabling the large-scale storage of renewable energy, Donald Sadoway’s invention is a huge step towards the deployment of carbon-free electricity generation,” says António Campinos, President of the European Patent Office. “He has spent his career studying electrochemistry and has transformed this expertise into an invention that represents a huge step forward in the transition to green energy.”

A new measurement record for strongest magnetic field in universe

Posted by in categories: energy, space

Breaking the previous record by 60 percent.

The team behind the first Chinese X-ray astronomy satellite, Insight-HXMT, has discovered the strongest magnetic field directly measured in the universe hitherto.

It is a known fact that neutron stars generate the strongest magnetic fields in the universe. These magnetic fields, close to a neutron star’s surface, can only be measured accurately and directly by looking for cyclon resonance scattering features (CRSF). The Insight-HXMT team discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary Swift J0243.6+6124, which translates to a surface magnetic field of more than 1.6 billion Tesla.

Future Smart Homes Powered With Electronics Built on Stones

Posted by in categories: energy, food

What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with these materials, researchers have fabricated microsupercapacitors onto the surface of stone tiles. The devices, reported in ACS Nano, are durable and easily scaled up for customizable 3D power supplies.

It would be convenient if the surfaces in rooms could charge smart home devices or other small electronics without being connected to the electrical grid. And although stone is a widely used material for floors, countertops and decorative backsplashes, it hasn’t been integrated with energy storage devices, such as batteries and capacitors. But stones, even those that are polished and seem smooth, have microscopic bumps and divots, making it difficult to adhere electrical components to them. Researchers have recently figured out how to place microsupercapacitors, which have fast charging and discharging rates and excellent power supply storage, onto irregular surfaces with lasers. So, Bongchul Kang and colleagues wanted to adapt this approach to build microsupercapacitors on marble. For further information see the IDTechEx report on Supercapacitor Materials and Formats 2020–2040.

US witnesses 40-year-high spike in customer prices

Posted by in categories: energy, government

Since April 1980, the overall yearly growth in energy prices is at its highest level. Gasoline prices increased by 11.2 per cent last month and a startling 59.9 per cent over the previous year, accounting for half of the monthly rise.

As per Government data released on Wednesday (July 13), in June, the United States saw a new peak of 9.1 per cent inflation. This faster-than-expected increase in the consumer price index (CPI) was driven by significant increases in gasoline prices, reports AFP. The US Labor Department has reported that this 9.1 per cent CPI spike over the past 12 months to June was the fastest increase in 40 years, the last such increase was witnessed in November 1981.
