Nanoparticle gel unites oil and water in manufacturing-friendly approach

Novel gel-creation method could open applications in water filtration, other applications

15-Feb-2021

Oil and water may not mix, but adding the right nanoparticles to the recipe can convert these two immiscible fluids into an exotic gel with uses ranging from batteries to water filters to tint-changing smart windows. A new approach to creating this unusual class of soft materials could carry them ...

Magic in metal could help put excess carbon dioxide to good use

01-Jun-2018

The chunk of metal sitting on a table in Joel Rosenthal's office at the University of Delaware looks like it should belong in a wizard's pocket. Shiny silver with shocks of pink and splashes of gold, it's called bismuth, and it's currently used to make products ranging from shotgun pellets to ...

Coastal water absorbing more carbon dioxide

02-Feb-2018

As more carbon dioxide enters the atmosphere, the global ocean soaks up much of the excess, storing roughly 30 percent of the carbon dioxide emissions coming from human activities. In this sense, the ocean has acted as a buffer to slow down the greenhouse gas accumulation in the atmosphere and, ...

A sweeter way to make green products

12-Sep-2017

The shampoo you washed your hair with this morning. The balloons for the party. Refrigerators and sunglasses, medicine and mosquito repellent, guitar strings and fishing lures. These -- and thousands of other products we use every day -- contain chemicals made from petroleum. But researchers at ...

Small scale, big improvements

Molecular scale science may inform water purification methods, battery improvements

15-Jun-2017

Methods to improve water purification or build better batteries are problems that have challenged scientists for decades. Advances have inched forward, but rising demand moves the finish line further and further away. At the same time, the chemical reactions that make these improvements possible ...
