Interconnected materials containing networks are ubiquitous in the world around us—rubber, car tires, human and engineered tissues, woven sheets and chain mail armor. Engineers often want these ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting graphite to extreme pressure and heat, researchers synthesized a rare ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...

at least some of the austenite is transformed into the hexagonal martensite structure. When the steel is put under increasing stress, the hexagonal lattice switches to the final, body-centered cubic ...

because while diamond forms with a tetrahedral arrangement in its carbon lattice (known as diamond cubic), lonsdaleite forms a hexagonal one that increases thermal stability and hardness.

Lonsdaleite is an allotrope of carbon that has a hexagonal crystal structure, rather than the cubic lattice of conventional diamond. It was first identified in 1967 from the Canyon Diablo meteorite, ...

Synthetic hexagonal diamond surpasses natural diamonds in hardness Developed using high-pressure graphene heating for improved stability Potential applications in drilling, machining, and thermal ...

As opposed to ice I’s hexagonal crystalline structure, ice VII has a cubic structure. Plastic ice VII has the same cubic structure as regular ice VII, but as the name suggests it’s a little ...
