An alloy that retains its memory at high temperatures

Using computer simulation, Alberto Ferrari calculated a design proposal for a shape memory alloy that retains its efficiency for a long time even at high temperatures. Alexander Paulsen manufactured it and experimentally ...

Additive manufacturing and Ni/Ti metal bolster cooling technology

Scientists at the University of Maryland (UMD) have developed a novel elastocaloric cooling material, comprised of a nickel (Ni)-titanium (Ti) alloy and sculpted using additive technology, that is highly efficient, eco-friendly ...

Robot arms with the flexibility of an elephant's trunk

Unlike conventional robot arms with hinged and swivel joints, new flexible arms being developed by Professor Stefan Seelecke and his research group at Saarland University are constructed using muscles made from shape-memory ...
