Nanotechnologists have succeeded in controlling the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution. The discovery has ...
Using doped polymers, researchers have made magnetic nanoparticles in a rainbow of colors, including white (ACS Appl. Polym. Mater. 2020, DOI: 10.1021/acsapm.0c00038). This broad range of colors has ...
A researcher from the University of Essex has succeeded in inducing the experience of colour in the blind part of a partially sighted patient’s visual field. Using a magnetic coil to stimulate the ...
