Double-walled nanotubes have electro-optical advantages

01-Apr-2020

One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when ...

Water-free way to make MXenes

Discovery could mean new uses for the promising nanomaterials

18-Mar-2020

Ten years after producing the first sample of the now widely studied family of nanomaterials, called MXenes, Drexel University researchers have discovered a different way to make the atom-thin material that presents a number of new opportunities for using it. The new discovery removes water from ...

Fast-charging damages electric car batteries

Just 25 industry-standard fast charging cycles can ruin a car's batteries

16-Mar-2020

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, write engineers at the University of California, Riverside in a new study published in Energy Storage. To remedy this, the ...

A possible end to 'forever' chemicals

Excess electrons could help break the strong chemical bonds in products that contaminate water supplies

13-Mar-2020

Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across ...

Chemists create new artificial enzyme

Triple-stranded molecule may help put chemistry's holy grail in reach

12-Mar-2020

Enzymes are nature's powerhouses. Found in the cells of all animals, plants, and every other living organism, they accelerate the chemical reactions that trigger thousands of biological functions--from forming neurons to digesting food. They perform their jobs so selectively and so ...

Manipulating atoms to make better superconductors

05-Mar-2020

Scientists have been interested in superconductors - materials that transmit electricity without losing energy - for a long time because of their potential for advancing sustainable energy production. However, major advances have been limited because most materials that conduct electricity have ...

'Smart water' may aid oil recovery

04-Mar-2020

Now there's evidence that oil and water do mix. Sort of. Scientists at Rice University's Brown School of Engineering show that microscopic saltwater droplets emulsify crude oil when each has the right composition. Understanding how they combine is important to enhanced oil recovery. Rice chemical ...

Unique material could unlock new functionality in semiconductors

New ferroelectric material can be manipulated using light in previously impossible ways

03-Mar-2020

If new and promising semiconductor materials are to make it into our phones, computers, and other increasingly capable electronics, researchers must obtain greater control over how those materials function. In an article published in Science Advances, Rensselaer Polytechnic Institute researchers ...
