Evolutional History Of Metal Chalcogenide Supertetrahedral Clusters (Material Science)

Leave a comment

Nanoclusters, which consist of several or even thousands of atoms, represent an important intermediate state between microscopic atoms and macroscopic matter. A profound comprehension of the composition, structure, and properties of nanoclusters is crucial for exploring or extending their functional applications. Among the numerous types of nanoclusters, metal chalcogenide supertetrahedral clusters (MCSCs) have attracted great … Continue reading Evolutional History Of Metal Chalcogenide Supertetrahedral Clusters (Material Science) →

Charting the Expansion History of the Universe with Supernovae (Astronomy)

Leave a comment

An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven correct with future, higher-quality data from the Subaru Telescope and other observatories, these results could indicate still unknown … Continue reading Charting the Expansion History of the Universe with Supernovae (Astronomy) →
