New technique builds super-hard metals from nanoparticles

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...

Ученые из Ярославля разработали инновационный полимерный материал (runews24.ru)

"Specialists from the Yaroslavl Research Institute of Space and Aviation Materials (NIICAM) presented their innovative polymer material aristide. According to the creators, its weight is 10 times less than aviation aluminum, and it is also able to withstand temperatures up to 1300 degrees.

The innovative development is positioned not only as a potential replacement for aviation aluminum and epoxy polymers used in the space industry, but also can have a wide military application. So, according to the Yaroslavl authorities, the new material is able to withstand a hit from a small-caliber combat weapon and "gradually regenerate".

Sounds pretty badass for a new generation aircraft.

NIF experiments probe carbon at record pressures

Carbon is one of the most ubiquitous elements in existence. As the fourth most abundant element in the universe, a building block for all known life and a material that sits in the interior of carbon-rich exoplanets, the element has been subject to intense investigation by scientists.

"With its huge energy storage density, POWERPASTE is also an interesting option for cars, delivery vehicles and range extenders in battery-powered electric vehicles. Similarly, it could also significantly extend the flight time of large drones, which would thereby be able to fly for several hours rather than a mere 20 minutes"

Hydrogen-powered drives for e-scooters

Hydrogen is regarded by many as the future of propulsion technology. The first hydrogen-powered cars are already in action on German roads. In the case of e-scooters, however, installation of a high-pressure tank to store the hydrogen is impractical. An alternative here is POWERPASTE. This...

NOVA--Beyond the Elements: Indestructible

Glass so strong you can jump on it, a rubber-like coating tough enough to absorb a bomb blast, endless varieties of plastic. Scientists and engineers have created virtually indestructible versions of common materials by manipulating the chains of interlocking atoms that give them strength—but have they made them too tough? Host David Pogue explores the fantastic chemistry behind the everyday materials we depend on, and how the quest for durability can be balanced with products’ environmental impact.

Coca-Cola Begins Testing a Paper Bottle - Slashdot

"Coca-Cola is to test a paper bottle as part of a longer-term bid to eliminate plastic from its packaging entirely," reports the BBC: The prototype is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner. But the goal is to create a 100% recyclable...

NOVA--Beyond the Elements: Reactions

Just about every solid, liquid, or gas in the world as we know it begins with reactions between individual atoms and molecules. Host David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that’s allowed farmers to feed a global population by the billions—a reaction that when reversed, unleashes the powerful chemistry of high explosives.

MIT creates a camera lens that can change focus without moving parts

Modern zoom lenses work wonderfully, but crack one open and you'll be greeted by a truly terrifying degree of micro-mechanical complexity, with 20 or more polished glass elements set to move in different directions at varying rates when you work the zoom or focus rings. The fact that these things…

Artificial magnetic texture induced in graphene could boost spintronics

Graphene has a lot of useful properties, but magnetism isn’t one of them – at least, not usually. In a new study led by the University at Buffalo, researchers have managed to induce an “artificial magnetic texture” in the material, which could have major implications for the emerging field of…

New concrete recipe improves its carbon capture efficiency

Concrete is one of the world’s most commonly used materials, and unfortunately its production is a major source of carbon dioxide in the atmosphere. Now, engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fast as usual, hopefully turning it into a useful…

Without even reading the article first, weathering related absorption is significant even in "normal" concrete over a longish period of time. Not enough to offset production emissions but appreciable still, but there's also work being done on that end as well. For some years already there's been a steady stream of news proclaiming breakthroughs in this area but nothing truly revolutionary that I know of is being widely used yet. Don't know what the hold-up is, probably high initial capital investment inertia, lack of long term data, small profit margins and such.

Looks interesting, though scaling such things up always bring fresh challenges.

It's a pity that when mentioning the Sumitomo Fluidized Bed Reactor at around the 9 minute mark, he couldn't bring himself to mention that it's burns not only "low grade coals, which are incombustible, but also other diverse range of non-fossil fuels (wood base biomasses, scrap tires, scrap plastics, sludge, etc.)"

In at least some respects arguably another example of what was old being new again.
