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 ...
Making computers interact with physical objects is a favorite of the HCI gurus out there, but these builds usually take the form of image recognition of barcodes or colors. Of course there are new ...
