Submission + - SPAM: World's strongest glass that's as hard as diamond discovered

Submitted by Hmmmmmm
Hmmmmmm writes: Scientists in China have developed the hardest and strongest glassy material known so far that can scratch diamond crystals with ease.

The researchers, including those from Yanshan University in China, noted that the new material – tentatively named AM-III – has “outstanding” mechanical and electronic properties, and could find applications in solar cells due to its “ultra-high” strength and wear resistance.

Analysis of the material, published in the journal National Science Review, revealed that its hardness reached 113 gigapascals (GPa) while natural diamond stone usually scores 50 to 70 on the same test.

According to the scientists, AM-III has tunable energy absorption properties comparable to semiconductors commonly used in solar cells such as hydrogenated amorphous silicon films.

While in diamond crystals, the organised internal structure of its atoms and molecules contribute to their immense strength and hardness, in AM-III the researchers found that a combination of order and disorder of its molecules give rise to its strange properties.

Using fullerenes, which are materials made of hollow football-like arrangements of carbon atoms, the researchers produced different types of glassy materials with varying molecular organisation among which AM-III had the highest order of atoms and molecules.

Increasing the order further, the scientists observed, could potentially kill the semiconductivity and other properties that required the atoms and molecules to be chaotic.

Where's the outrage at the billions of devices that already have front facing cameras? This isn't about that, it's about ensuring a minimum user experience - especially with Teams being baked into the OS. The requirement is only for mobile devices (tablets, laptops), desktops are exempt...

In this case, though, it's just normal people who don't understand markets at all but are trying to make some money. Yet they don't know to look and see why prices are being driven up.., with actors who heavily invested millions when DOGE in '19 driving up the price with large buys and multiple small sells (that is just one wallet).

DOGE is a joke - when over 70% of it is held by 100 wallets, with majority of the largest holders all buying millions $ worth of DOGE all in the same time frame (Jan - July 2019). You can literally look up the block transactions and see which wallets are manufacturing volume to drive up the price in this pump and dump.

Downstream components may come from China, and final assembly of certain components may happen in China - but actual fab happens in Taiwan, Korea, Singapore, Japan, US etc. China has struggled for several decades to break into the semiconductor industry and has failed to do so - it's not exactly something that can be copied and fabricated, while simultaneously having the ability to design and fab the next generation. China will catch up, but it won't be anytime soon.
