Probing Diversity of Type II Supernovae with the Chinese Space Station Telescope

Universe, 2023
Type II supernovae (SNe II), which show abundant hydrogen in their spectra, belong to a class of SNe with diverse observed properties. It is commonly accepted that SNe II are produced by core collapse and explosion of massive stars.

Software design for the control system for Small-Size Telescopes with single-mirror of the Cherenkov Telescope Array

, 2015
The Small-Size Telescope with single-mirror (SST-1M) is a 4 m Davies-Cotton telescope and is among the proposed telescope designs for the Cherenkov Telescope Array (CTA). It is conceived to provide the high-energy ($>$ few TeV) coverage.

Imagining the Heavens: Adam Elsheimer’s Flight into Egypt and the Renaissance Night Sky

Journal for the History of Knowledge, 2021
Adam Elsheimer’s The Flight into Egypt (1609) has triggered a longstanding debate among art historians. For the last five decades, Elsheimer’s novel naturalistic representation of the night sky in his painting on copper has been linked to Galileo’s ...

From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

Advanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.

Alkoxysulfonium Salts Unlock Access to New Aryl Sulfonium Salts for Cross‐Coupling

Angewandte Chemie, EarlyView.
Hard‐to‐access (hetero)aryl sulfonium salts are prepared using stable methoxysulfonium salts in combination with the magnesiation of (hetero)aryl bromides. The approach allows access to aryl sulfonium salts bearing electron‐deficient (hetero)aryl rings, or electron‐rich aryl motifs in which the sulfonium motif resides at an alternative position on the ...
