In fact aluminum is famous for not occurring natively: Despite being the third most abundant element in the earth's crust, accounting for over 8% of the total weight of the crust, it was completely unknown as a
Some commodities—most notably, steel—will also play an enabling role across technologies requiring additional infrastructure.Rare-earth metalsThe required pace of transition means that the availability of certain raw materials will need to ...
Most of the survival knives I own are made from a single type of steel, but that’s not the case with Fallkniven’s fixed blade outdoor knives. The A1 uses a laminate featuring 420J outer cladding with a VG-10 core. The VG-10 core is hardened to 59 HRC, and the geometry of the...

freedom. For example, giant magnetoresistance82—an effect that depends on the magnetic degrees of freedom—is widely used in computer memory (MRAM). Arguably the materials with the most promise of multi-functional behavior are those with strongly interacting electrons, which can lead to enhanced ...
We will support the development of firefighting and rescue equipment and materials in regional central cities, the central and western regions and the three northeastern provinces, and support the firefighting and rescue stations in the most impoverished "three regions and three autonomous prefectures" ...
These data suggest that most chitin is produced in Stage II and not the FZ, while most chitinase activity occurs in Stages II-III. The lack of chitinase activity in the FZ, concomitant with high expression of different chitinase genes there may suggest a lack of translation, or the generation...
The drummer was phenomenal, and of course Matthias Sollak was incredible on lead guitar, and while they aren’t the most engaging live band, they managed to translate what is an incredibly dense, layered sound into the live setting rather well. As for Swallow the Sun, this was maybe my ...
