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

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.

Robotic soft matter’ bends, rotates and crawls when hit with light.
Northwestern University researchers have developed a family of soft materials that imitates living creatures.
When hit with light, the film-thin materials come alive — bending, rotating and even crawling on surfaces.
Called “robotic soft matter" by the Northwestern team, the materials move without complex hardware, hydraulics or electricity. The researchers believe the lifelike materials could carry out many tasks, with potential applications in energy, environmental remediation and advanced medicine. More
