Researchers found that twisting 2D layers at atypically large angles opens up potentially useful energy gaps in the material’s band structure. The results suggest a new way to tune materials for optoelectronic applications and provides a platform for exploring novel “moiré” phenomena beyond those observed at small twist angles. Read more »

New Insights Lead to Better Next-Gen Solar Cells
Perovskites show great promise to reduce the costs of solar power but are not yet durable enough to be commercially viable. Researchers used simultaneous characterization techniques to understand why a simplified fabrication process works so well, providing key insights to nudge perovskites closer to commercialization.

Case Study of Aerosol Particles Influenced by Wildfire
Researchers studied atmospheric aerosols influenced by wildfires in the Pacific Northwest. They examined the connection between particle size, chemical composition, and phase state, in particles collected during the day and at night. The information is important for modeling the effects of wildfire smoke on atmospheric properties. Read more »
