Baratos, pequenos, brilham quando expostos a um campo magnético, eis um novo tipo de écrans:
Tiny iron oxide particles promise big benefits for display technology
By Steven Hondrogiannis
Chemists at the University of California, Riverside, are developing a future display technology using nanoscale-sized iron oxide rods that shine when exposed to an external magnetic field. Though in its early stages, the research could pave the way for producing magnetically responsive, ultra high-res displays with significantly reduced dimensions and power demands.
The researchers have shown in the past that by using a simple magnet, the color of iron oxide particles suspended in water can be manipulated in response to the strength and orientation of a magnetic field.
The latest development is the application of silica to the iron oxide particles to form chains of light emitting particles that refract the visible light into brilliant colors when magnetically charged.
