A radical cation salt of new aromatic compound produced a molecular conductor with three-dimensional conduction pathways. The conduction pathways were based on intermolecular interactions via ethyl groups, which demonstrated that unpaired electrons move in various directions in the solid passing through both aromatic rings and ethyl groups. Such features were related to doubly degenerated narrow bands at the Fermi level, making it a totally different conductor from any known conductors.

Osaka Metropolitan University researchers discovered why chemical reactions slow down under high-power ultrasound. Excessive ultrasonic output distorts waveforms, reducing active bubble formation and reaction rates. The study classifies three reaction regions, offering guidance for optimizing sonochemistry in applications like nanoparticle synthesis and PFAS degradation.

Using a combination of telescopes, including the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, and the SOAR telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab, astronomers have characterized the closest supernova linked to a fast X-ray transient. The observations reveal that these bright blasts of X-rays may be the result of a ‘failed’ explosive death of a massive star.

Rice’s Lei Li wins NSF CAREER Award to develop a new generation of wearable medical imaging technology capable of visualizing deep tissue function in real time.

“Space ice” contains tiny crystals and is not, as previously assumed, a completely disordered material like liquid water, according to a new study by scientists at UCL (University College London) and the University of Cambridge.
