While titanium hip and knee implants do restore mobility to a great many people, they’re still subject to failure. A new alloy could help change that, simply by adding a smidge of bendy, bacteria-killing gallium to the mix.Continue ReadingCategory: Med… Continue reading A dash of gallium may make for stabler hip and knee implants
MIT scientists have discovered an intriguing new way to produce hydrogen fuel, using just soda cans, seawater and coffee grounds. The team says the chemical reaction could be put to work powering engines or fuel cells in marine vehicles that suck in se… Continue reading Seawater-slurping hydrogen reactor able to power a sub for 30 days
While titanium implants such as artificial hips can greatly improve patients’ lives, they’re also subject to serious bacterial infections. An experimental new antibacterial titanium alloy, however, could make such problems a thing of the past.Continue … Continue reading Special titanium alloy lets implants fight off bacterial infections
Researchers have created a new family of nanomaterials by alloying phosphorus with arsenic to create single-atom-thick ribbons that are highly conductive, making them ideal candidates for use in next-generation batteries, solar cells and quantum comput… Continue reading Novel nanoribbons could improve battery & solar cell efficiency
Strength and flexibility are two opposites that usually need to be balanced in steel. But now engineers at Purdue University and Sandia National Labs have developed a new treatment that can be applied to steel alloys to make them both stronger and more… Continue reading New treatment makes steel alloys both stronger and more flexible
At the level pursued by many Hackaday readers, the advent of affordable 3D printing has revolutionised prototyping, as long as the resolution of a desktop printer is adequate and the …read more Continue reading 3D Print For Extreme Temperatures (But Only If You’re NASA)
One factor limiting the output of today’s power stations is the metals used in the blades, bearings and seals of their steam turbines, which tend to soften and elongate well before their melting point. Solve these problems, and you could conceivably ra… Continue reading Heat-loving lightweight superalloy promises higher turbine efficiency
Researchers in New Zealand and Australia have grown tiny metal snowflakes, cubes, rods and other shapes. The nanocrystals form like snow out of a liquid metal, demonstrated an intriguing new potential method for manufacturing nanoscale structures.Conti… Continue reading Tiny metal snowflakes demonstrate new nanoscale manufacturing methods
A simple alloy has claimed the crown for toughest material ever recorded. In a new study, a team led by researchers at Berkeley Lab ran the alloy through a series of tests and discovered not only its incredible toughness, but high strength and ductilit… Continue reading Simple alloy claims crown of toughest material ever recorded
While most metals feature some degree of elasticity, some respond better than others to being bent out of shape. Scientists experimenting with the makeup of these materials have developed a novel, copper-based alloy they say would be simple to produce … Continue reading Novel alloy boasts unparalleled elasticity at room temperature
