Nanoparticles accumulate quickly in wetland sediment

(Phys.org) —A Duke University team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indirectly damage ...

Smartgels are thicker than water

Transforming substances from liquids into gels plays an important role across many industries, including cosmetics, medicine, and energy. But the transformation process, called gelation, where manufacturers add chemical thickeners ...

The promise and peril of nanotechnology

Scientists at Northwestern University have found a way to detect metastatic breast cancer by arranging strands of DNA into spherical shapes and using them to cover a tiny particle of gold, creating a "nano-flare" that lights ...

Carbon dioxide paves the way to unique nanomaterials

In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation ...

Gold nanoparticles give an edge in recycling CO2

(Phys.org) —It's a 21st-century alchemist's dream: turning Earth's superabundance of carbon dioxide—a greenhouse gas—into fuel or useful industrial chemicals. Researchers from Brown have shown that finely tuned gold ...
