Scientists unveil first method for controlling the growth of metal crystals
Researchers have announced the first ever method for controlling the growth of metal-crystals from single atoms.
Organic crystal demonstrates superelasticity
(Phys.org) —Not only rubber is elastic: There is also another, completely different form of elasticity known as superelasticity. This phenomenon results from a change in crystal structure and was previously ...
Atomic mechanism for historic materials transformation
(Phys.org) —SLAC-led researchers have made the first direct measurements of a small and extremely rapid atomic rearrangement, associated with a class called martensitic transformations, that dramatically ...
Probing metal solidification nondestructively
(Phys.org) —Los Alamos researchers and collaborators have used nondestructive imaging techniques to study the solidification of metal alloy samples. The team used complementary methods of proton radiography ...
Glasses strong as steel: A fast way to find the best
Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel.
Researchers model spent nuclear fuels
(Phys.org) —Lawrence Livermore scientists have modeled actinide-based alloys, such as spent nuclear fuel, in an effort to predict the impact of evolving fuel chemistry on material performance.
Titanium clubs can cause golf course fires, study finds
Titanium alloy golf clubs can cause dangerous wildfires, according to UC Irvine scientists. When a club coated with the lightweight metal is swung and strikes a rock, it creates sparks that can heat to more than 3,000 degrees ...
Metal in the heart is non-hazardous to health
Materials Scientists at the University of Jena examine implants made of nickel-titanium alloy in a long-term study: The team led by Professor Rettenmayr and his colleague Dr. Andreas Undisz report in the ...
3D-printed metal bike frame is light but strong
X-ray diffraction technique 'maps' strain and crack propagation in metallic tubing
A team of researchers exploring the intergranular stress corrosion cracking of a type of metallic tubing used within nuclear power plants has developed a technique to both map and predict its propagation.
What makes superalloys super: Hierarchical microstructure of a superalloy
Materials in high-performance turbines have to withstand not only powerful mechanical forces, they also have to maintain their chemical and mechanical properties almost up to their melting points. For this ...
A new nanomaterial offers hope for better detection and treatment of breast cancer
A collaboration of scientists (from Denmark, Brazil, Germany and the UK) developing a new detection and treatment method for breast cancer have recently published early results from their work in the Journal of ...
Remembrances of things past: Researchers discover nanoscale shape-memory oxide
(Phys.org) —Listen up nickel-titanium and all you other shape-memory alloys, there's a new kid on the block that just claimed the championship for elasticity and is primed to take over the shape memory ...
Artificial heart to pump human waste into future robots
A new device capable of pumping human waste into the "engine room" of a self-sustaining robot has been created by a group of researchers from Bristol.
