You’ve likely heard of Nitinol wire before, but we suspect the common base knowledge doesn’t go much beyond repeating that it’s a shape-memory alloy. [Bill Hammack], the Engineer Guy, takes us on a ...

A new material that once deformed will automatically return to its original shape when heated has been developed by researchers in the US. While this is not the first such “shape-memory metal”, the ...

A rover on the Moon has metal wheels that can flex around rocky obstacles, then reshape back to their original form. On Earth, surgeons install tiny mesh tubes that can dilate a heart patient’s blood ...

A good tire means a lot when the nearest roadside assistance is 34 million miles (55 million kilometers) away. For future rovers that will explore the surface of Mars, NASA scientists have created a ...

Another Kickstarter, another opportunity for people to get mad at delayed and poorly functioning (if delivered at all) gadgets. This project aims to make airless tires for bikes and scooters using ...

A German research team has prototyped an extraordinary heating/cooling system that stresses and unloads nickel-titanium "muscle wires" to create heated and cooled air at twice the efficiency of a heat ...

A new class of materials known as "magnetic shape-memory foams" has been developed. The foam consists of a nickel-manganese-gallium alloy whose structure resembles a piece of Swiss cheese with small ...

Here’s an idea for a surgical procedure that would be right at home as a plot device in a science fiction film long before it receives FDA approval. It combines robot technology with a metal alloy ...

A Shape-Memory, Metal–Polyphenol–Coated Scaffold for Sequential Repair of Infected Bone Defects. Schematic illustration of the design and therapeutic mechanism of the PT/CHA@TA-Mg scaffold. Citric ...
