Spectroscopic Fingerprinting of Coordination‐driven Spin States in Metal‐organic Architectures

Chemistry – A European Journal, EarlyView.
Coordination geometry controls spin states in Co‐TCNQ frameworks. Combined theory and XAS confirm the high‐spin Co2+ on graphene and establish a direct approach for spin‐state assignment in metal‐organic systems. ABSTRACT Determining the local geometry of metal‐organic architecture on substrates is challenging, as substrate interactions can alter the ...

Multiepoch Observations of the Nearby Spiral Galaxy NGC 3938 with the Chandra X-Ray Observatory

The Astronomical Journal
We present an analysis of two epochs of ACIS observations of the SA(s)c spiral galaxy NGC 3938 with the Chandra X-ray Observatory. The total exposure time of the observations was 95 ks, with a limiting unabsorbed luminosity of ≈10 ^38 erg s ^−1 assuming ...

Crispant analysis in zebrafish as a tool for rapid functional screening of disease-causing genes for bone fragility

eLife
Heritable fragile bone disorders (FBDs), ranging from multifactorial to rare monogenic conditions, are characterized by an elevated fracture risk. Validating causative genes and understanding their mechanisms remain challenging.

Dual‐Mode Thio‐MacMillan Organocatalysts: Stereoselective Diels–Alder Reactions or Sacrificial Self‐Cyclization to N‐Bridged Bicyclic Lactams

Chemistry – A European Journal, EarlyView.
The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

Phosphorus‐Structured Gel Electrolytes Enable Dual Protection for Thermal Runaway‐Resistant Lithium Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The PD‐VI GPE synthesized via in situ γ‐ray polymerization facilitates formation of a dense F/P‐rich SEI layer, enabling stable Li deposition while suppressing interfacial side reactions. The phosphorus‐containing framework enhances separator thermal stability and effectively mitigates O2 release from cathodes, demonstrating improved safety under the ...
