What new materials are there?

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.

Enjoy flat lenses from Metalenz

“Metalenz is commercializing a revolutionary flat optical technology and transforming optical sensing in consumer electronics and automotive markets. Built on a foundational innovation in meta-optics from Harvard University, Metalenz’s technology enables significant reduction in the complexity and size of optical modules while improving system performance.”

"A new startup out of Harvard Labs has invented a way to print camera lenses 10,000 at a time just like computer chips in the same semiconductor foundries that make chips for computers and phones."

"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"

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.

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.

I wonder how well it would work in practice...

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.)"
