Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

To Telescope or Not To Telescope?
With the rapidly growing number of Internet-accessible and Internet-controlled research-grade telescopes becoming available, astronomy educators are rushing to create authentic research-programs for students that leverage these new resources. To date, the most successful programs are those that focus on upper-level science-focused students or highly ...

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].

L’observatoire de Juvisy-sur-Orge, l’« univers d’un chercheur » à sauvegarder
In 1882, Camille Flammarion was given a property at Juvisy-sur-Orge by one of his admirers. He transformed the house into an astronomical observatory and installed what was for its day advanced scientific equipment.

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

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