New polymer mesophase structure discovered

Polymers, large molecules made up of repeating smaller molecules called monomers, are found in nearly everything we use in our day-to-day lives. Polymers can be natural or created synthetically. Natural polymers, also called biopolymers, include DNA, proteins, and materials like silk, gelatin, and collagen. Synthetic polymers make up many different kinds of materials, including plastic, […]

Pentacene derivative has 100 times more light durability than conventional products

Due to high hole mobility, pentacene and its derivatives have been the representative organic semiconductor and have been the subject of much research, both basic and applied. In particular, they are expected to be applied to semiconductor devices, such as field-effect transistors. In addition, organic semiconductors have the advantage of being inexpensive to produce through […]

These tiny marsupials survived wildfires only to face extinction from feral cats

Few marsupials have gone from miraculous survival to the brink of extinction as quickly as the Kangaroo Island dunnart. In 2019 and 2020, devastating fires burned nearly 10 million hectares of southeastern Australia. The flames threatened hundreds of species with extinction, but the Kangaroo Island dunnart (Sminthopsis aitkeni) — which already numbered less than 500 […]

Watching the death of a rare giant star

Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. By tracing molecular emissions in the outflows around the red hypergiant star VY Canis Majoris, astronomers obtained the first detailed map of the star’s envelope, which sheds light on the mechanisms involved in the final […]
