Materials scientists typically use solution-phase transmission electron microscopy (TEM) to reveal the unique physiochemical properties of three-dimensional (3-D) structures of nanocrystals. In a new report on Science Advances, ...
By analyzing archival radial velocity data, astronomers have detected a new warm-Neptune alien world. The newfound exoplanet, designated HD 183579b (or TOI-1055b) is about three and a half times larger and almost 20 times ...
For the first time, hard-to-find lithium has been identified and measured in the atmosphere of burned out stars called white dwarfs, according to a study led by the University of North Carolina at Chapel Hill published online ...

Moiré superlattices that are located within van der Waals (vdW) heterostructures can trap long-lived interlayer excitons to form ordered quantum dot arrays, paving the way for unprecedented optoelectronic and quantum information ...
A planet observed crossing in front of, or transiting, a low-mass star has been determined to be about the size of Jupiter. While hundreds of Jupiter-sized planets have been discovered orbiting larger sun-like stars, it is ...
