What new materials are there?

Interesting quote:

Although the technology behind this discovery—atom interferometry—might seem arcane, atom interferometry may one day be used to detect gravitational waves and help us navigate better than GPS, researchers have said.

In a First, an 'Atomic Fountain' Has Measured the Curvature of Spacetime

The atom interferometry technique uses the effects of time dilation to reveal subtle changes in gravity’s strength

Wonder if that could work in Space:
- energy would be harvested from solar energy
- Separation could be eased by the fact that particles will remain in suspension after the Zap procedure (low gravity) easing the sorting process through momentum sorting.

The City University of Hong Kong has two heat-busting claims to fame: Elinvar alloys that retains stiffness at 726 Celsius and Structured Thermal Armor that prevents the Leidenfrost effect up to 1,150 C.

Just what Raptor 2 and film cooling need. A nice blurb about using ice to boil water at phys.org too.

New hydrogen storage material steps on the gas

The real problem is all the other problems that hydrogen loves to cause, like the various forms of hydrogen attack (aka 'hydrogen literally infiltrates molecules at various temperature ranges', one example of the 'high-temperature hydrogen attack' caused a massive explosion at a refinery a while back).

The wonder material graphene may have found its killer app

It will help decarbonise industry, produce greener concrete and make hydrogen
www.economist.com www.economist.com

Yet despite this promise, apart from a few niche uses in electronics, water filtration and some specialist sports equipment, graphene remains largely unemployed. Certainly, no killer application of the sort predicted when the stuff was discovered has emerged. But that could be about to change. Concrete is as far from superconductivity on the technological sexiness spectrum as it is possible to get. Yet it is an important material and of great concern to those attempting to slow down global warming, because the process of making it inevitably releases carbon dioxide. And graphene may hold the key to reducing that contribution considerably.

The idea is that loop can be used to strip carbon from methane gas flows, such as those found in various industrial processes, water-treatment plants and biogas reactors, as well as oil wells and landfill sites. That gets rid of methane, a potent pollutant, without generating CO2—which would be an inevitable outcome if the methane were, instead, burned. The hydrogen that is made can then be burned as fuel without producing any greenhouse gases and the graphene sold for other applications, such as an additive to toughen anti-corrosion paint—in exactly the same way that the grey paint used to protect Levidian’s shipping container from the elements has been treated.

Today's phys.org was quite good. Electron whirlpools observed...a 'quantum flute' made to influence light-an upside down design expands wide spectrum super camera abilities...a 'four stroke engine for atoms.' But here is the capper: "Mathematical calculations show that quantum communication across interstellar space should be possible."
 
Tsinghua University's Kai Liu has developed what phys.org calls a "Supramolecular adhesive with usable temperature range of 400 degrees Celsius." It was said that 'steel plates glued together withstood high shear forces at room temperature, in liquid nitrogen and at 200 degrees Celsius.' Hey, ELON!

Highly Transparent Solar Cell with 2D Atomic Sheet Successfully Fabricated

These near-invisible solar cells achieved an average visible transparency of 79%, meaning they can, in theory, be placed everywhere - building windows, the front panel of cars, and even human skin.

A research group has fabricated a highly transparent solar cell with a 2D atomic sheet. These near-invisible solar cells achieved an average visible transparency of 79%, meaning they can, in theory, be placed everywhere - building windows, the front panel of cars, and even human skin.

"The way in which we formed the solar cell resulted in a power conversion efficiency over 1000 times that of a device using a normal ITO electrode," pointed out Toshiaki Kato, corresponding author of the paper and associate professor at Tohoku University's Graduate School of Engineering.
