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, ...

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 ...

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.

When COVID-19 spread to the United States, the pandemic exposed two conflicting realities: a healthcare system that excels at high-cost, complex treatments while failing to provide sufficient access ...
