Soft material is powered by light and rotating magnetic fields.

Northwestern University researchers have developed a first-of-its-kind life-like material that acts as a soft robot. It can walk at human speed, pick up and transport cargo to a new location, climb up hills and even break-dance to release a particle.

Nearly 90% water by weight, the centimeter-sized robot moves without complex hardware, hydraulics or electricity. Instead, it is activated by light and walks in the direction of an external rotating magnetic field. More

Four takeaways from research could help scientists working to develop safe and effective vaccine.

A team from Northwestern including Northwestern Engineering’s Michael Jewett and Samuel Stupp has created guidelines to assist in developing a safe and effective vaccine for COVID-19.

Published July 21 in ACS Central Science, the principles were gleaned from early research on COVID-19 and data from the 2003 SARS outbreak, caused by SARS-CoV, a very similar virus to SARS-CoV-2, which causes COVID-19. More

Northwestern, MIT Researchers Develop Novel Materials for Energy and Sensing

Strategically varying composition of organic layers can "tune" color of light absorbed by perovskites.

A team of researchers from Northwestern University and the Massachusetts Institute of Technology (MIT) has demonstrated the ability to fine-tune the electronic properties of hybrid perovskite materials, which have drawn enormous interest as potential next-generation optoelectronic materials for devices such as solar cells and light sources.
 
The materials are classified as “hybrid” because they contain inorganic components like metals as well as organic molecules with elements like carbon and nitrogen, organized into nanoscale layers. In the paper “Tunable exciton binding energy in 2D hybrid layered perovskites through donor–acceptor interactions within the organic layer,” published July 6 in the journal Nature Chemistry, the researchers showed that by strategically varying the composition of the organic layers, they could tune the color of light absorbed by the perovskite and also the wavelength at which the material emitted light. Importantly, they accomplished this without substantially changing the inorganic component. More
