Scientists at Iowa Sate University recently discovered that simply looking at soil color is reasonably as accurate as time-consuming and expensive laboratory tests. Soil color can be used as a simple, ...

Single-walled carbon nanotubes, or sheets of one atom-thick layers of graphene rolled up into different sizes and shapes, have found many uses in electronics and new touch screen devices. By nature, ...

Processors who package meat want it to be free of pathogens and to have an attractive color in the display case. Use of the right elements for packaging can assist processors in reaching that goal.

The optical properties of carbon nanotube at visible wavelengths can be controlled electrically. Smart glass can change color or even go from opaque to transparent with just the flick of a switch.

Fluorescent carbon nanoparticles known as carbon dots could be a low-cost, biologically friendly alternative to quantum dots for sensing chemicals inside cells. Until now, carbon dots typically have ...

October 20, 2008 Electronic paper is one of those technologies that offers obvious benefits. It provides highly visible displays in direct sunlight due to its reliance on reflected light to view text ...
