When first responders are tending to accident victims with lacerations, it goes without saying that one of their primary goals is to control the bleeding. It may someday be possible for them to do so ...

A fluid that retains its magnetic structure when an external magnetic field is removed can form the basis of liquid bioelectronics 1. A ferrofluid is a substance consisting of nanometre-sized magnetic ...

Ferrofluids provide hermetic sealing when mechanical seals won't do. Magnetic fluids, also called ferrofluids, are advanced materials that can solve complex engineering problems — in particular ...

A microfluidic system with channels lined with magnetic liquids can ease the flow of samples and safely transport delicate cells, possibly helping to miniaturize microfluidic devices (Nature 2020, DOI ...

An electric field transforms an iron oxide nanoparticle suspension into a model for the emergence of complex dissipative structures. Researchers at Aalto University have shown that a nanoparticle ...
