Scientists capture colliding organic nanoparticles on video for first time

20-Nov-2017

A Northwestern University research team is the first to capture on video organic nanoparticles colliding and fusing together. This unprecedented view of "chemistry in motion" will aid Northwestern nanoscientists developing new drug delivery methods as well as demonstrate to researchers around the ...

Surface polarization in mixed media increases attraction among elements

16-Oct-2017

Despite their name, rare earth elements actually aren't that rare. Abundant in mines around the world, rare earths are used in many high-tech products, including visual displays, batteries, super conductors, and computer hard drives. But while they aren't necessarily tricky to find, the elements ...

Simultaneous design and nanomanufacturing speeds up fabrication

08-Aug-2017

Design and nanomanufacturing have collided inside of a Northwestern University laboratory. An interdisciplinary team of researchers has used mathematics and machine learning to design an optimal material for light management in solar cells, then fabricated the nanostructured surfaces ...

Tiny particles increase in air with ethanol-to-gasoline switch

18-Jul-2017

The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to a new study by a Northwestern University chemist, a National University of ...

Targeting PFOA threat to drinking water

12-Jun-2017

A highly toxic water pollutant, known as perfluorooctanoic acid (PFOA), last year caused a number of U.S. communities to close their drinking water supplies. Because of its historical use in Teflon production and other industrial processes as well as its environmental persistence, PFOA ...

Mystery of colloidal chains solved

17-May-2017

When Northwestern Engineering's Erik Luijten met Zbigniew Rozynek, they immediately became united by a mystery. Presenting at a conference in Norway, Rozynek, a researcher at Adam Mickiewicz University in Poznan, Poland, demonstrated something that looked almost like magic. When he poked a ...

Serendipity uncovers borophene's potential

24-Feb-2017

Almost one year ago, borophene didn't even exist. Now, just months after a Northwestern University and Argonne National Laboratory team discovered the material, another team led by Mark Hersam is already making strides toward understanding its complicated chemistry and realizing its electronic ...

Designing new materials from 'small' data

21-Feb-2017

Finding new functional materials is always tricky. But searching for very specific properties among a relatively small family of known materials is even more difficult. But a team from Northwestern Engineering and Los Alamos National Laboratory found a workaround. The group developed a novel ...

New design strategy for longer lasting batteries

24-Jan-2017

It's always exciting to bring home a new smartphone that seems to do anything, but it can be all downhill from there. With every charge and discharge cycle, the device's battery capacity lowers a little bit more -- eventually rendering the device completely useless. "Why does this degradation ...
