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, ...

A method can produce large quantities of pristine single-walled carbon nanotubes in select shades of the rainbow. The secret is a fine-tuned fabrication process -- and a small dose of carbon dioxide.

Because nanoscale objects are so incredibly small, they don't reflect enough light for even the best microscopes to discern details such as their color. A new lighting system, however, addresses that ...

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 ...

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 ...

Soil color can be used as a simple, inexpensive method to predict measurements of soil organic content to assess soil quality and better understand global carbon cycles. According to Iowa State ...

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, ...
