Beyond scifi: Manipulating liquid metals without contact

In a landmark discovery, FLEET University of Wollongong (UOW) researchers have realised the non-contact manipulation of liquid metal. The metals can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares by using a small voltage and a magnet. The liquid metal used is galinstan, an alloy of gallium, indium and tin, …

Trapping vortices in thin superfluid films

Physicists at the University of Queensland have shed light upon how tiny whirlpools (vortices) get stuck to obstacles in superfluids. Superfluids are a quantum substance that can flow without viscosity and hence do not slow down due to friction. A second defining feature of superfluids is that they only support quantised rotation – the vortices can only spin with strength …
