Researchers develop technique for enhanced reversibility of a phase-transforming material

(Phys.org) —A team of researchers at Minnesota State University has created a martensitic metal alloy that degrades very little after application of more than 16,000 thermal cycles. In their paper published in the journal ...

Shape-shifting alloys hold promise

Imagine untwisting a finger-size spring, then holding the flame from a lighter underneath the unraveled section. Like magic, it twirls itself into a spring again because the metal alloy remembered its original shape.

Using 'bacteria-eaters' to prevent infections on medical implant materials

They're ba-ack! But in a new disease-fighting role. Viruses that infect and kill bacteria—used to treat infections in the pre-antibiotic era a century ago and in the former Soviet Union today—may have a new role in preventing ...

Zinc: The perfect material for bioabsorbable stents?

(Phys.org) —In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked ...

Bioinspired material mimics squid beak

(Phys.org) —Researchers led by scientists at Case Western Reserve University have turned to an unlikely model to make medical devices safer and more comfortable—a squid's beak.

How do bacteria clog medical devices? Very quickly

A new study has examined how bacteria clog medical devices, and the result isn't pretty. The microbes join to create slimy ribbons that tangle and trap other passing bacteria, creating a full blockage in a startlingly short ...
