Designing surfaces that make water boil more efficiently

The boiling of water or other fluids is an energy-intensive step at the heart of a wide range of industrial processes, including most electricity generating plants, many chemical production systems, and even cooling systems ...

How to make bright quantum dots even brighter

Quantum dots are a kind of artificial atom: just a few nanometers in size and made of semiconductor materials, they can emit light of a specific color or even single photons, which is important for quantum technologies. The ...

Cleaning water with 'smart rust' and magnets

Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles they call "smart rust" that actually makes it cleaner. Smart rust can attract many substances, including ...

Confirmed: Global floods, droughts worsening with warming

The intensity of extreme drought and rainfall has "sharply" increased over the past 20 years, according to a study published Monday in the journal Nature Water. These aren't merely tough weather events, they are leading to ...

Sensor detects toxins in drinking water sources

University of Cincinnati researchers have developed a sensor that detects toxins from algal blooms that taint surface water such as rivers, lakes and streams. Early detection of these toxins can aid water treatment plants ...
