US scientists have observed metal cracking and fusing back together, in a discovery that could pave the way for self-healing machines, vehicles and bridges.
Scientists described how pieces of pure platinum and copper spontaneously healed cracks caused by metal fatigue during nanoscale experiments that had been designed to study how such cracks form and spread in metal placed under stress.
The extraordinary material has set a new record for exhibiting magnetoresistance at room temperature.
An alloy of chromium, cobalt, and nickel has just given us the highest fracture toughness ever measured in a material on Earth.
Physicists observed a strange new type of behaviour in a magnetic material when it's heated up. The magnetic spins 'freeze' into a static pattern when the temperature rises.
Scientists have found a new way to structure carbon at the nanoscale, making a super-light material that's superior to diamond on the strength-to-density ratio.
Scientists have found naturally occurring superconducting materials in extraterrestrial objects for the first time, discovering superconductive grains embedded inside two distinct meteorites that crash-landed on Earth.
A team of U.S. scientists has observed a new state of matter at the interface between two oxide materials. The discovery shows electrons can bind together in ways similar to how quarks combine to form neutrons and protons.
Researchers long ago theorized that if hydrogen gas were exposed to enough pressure, it would transition into a metal. Recent results indicate that hydrogen does become a solid at 425 gigapascals.
Cement production is one of the world’s leading contributors of CO2 emissions. Now, US researchers have combined sand, a hydrogel, and bacteria into a living material that has similar strength to cement-based mortar.
Harry Potter’s ‘invisibility cloak’ appears closer to reality as Canadian camouflage manufacturer Hyperstealth Biotechnology has applied for patents on its ‘Quantum Stealth’ material.
Engineers have cooked up a material made of carbon nanotubes that is 10 times blacker than anything that has previously been reported.
Swiss researchers have now identified an unusual way to prevent water from forming ice crystals, so even at extreme sub-zero temperatures it retains the amorphous characteristics of a liquid.
U.S. researchers have discovered that a high-strength polymer called "PBDT" has a rare double helix structure, opening possibilities for use in a variety of applications, for instance lightweight aerospace materials.
Hexagonal Boron Nitride ( hBN ) which is sometimes referred to as ‘white graphene’ and graphene itself are very compatible when layered together, providing advantages in bonding strength.
