Scientists make battery electrodes from waste eggshells

(Phys.org)—Americans consume 76 billion eggs per year, and while some of the eggshell waste is used for fertilizer or dietary supplements, the majority of these eggshells are thrown away. In a new study, researchers at ...

Scientists grow ultrahigh-purity carbon nanotubes

(Phys.org) —Single-walled carbon nanotubes (SWCNTs) are being widely studied for their potential applications in many areas; for example, as electrode materials for energy storage, as transparent conductive films, and as ...

Wires turn salt water into freshwater

(Phys.org) -- As a rising global population and increasing standard of living drive demand for freshwater, many researchers are developing new techniques to desalinate salt water. Among them is a team of scientists from The ...

Building a better microbial fuel cell—using paper

The concept behind microbial fuel cells, which rely on bacteria to generate an electrical current, is more than a century old. But turning that concept into a usable tool has been a long process. Microbial fuel cells, or ...

3D graphene: Solar cells' new platinum?

One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.
