Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

Homoleptic Bismuth Alkynes: Isolable Reagents for Selective Alkynyl Radical Transfer

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The first series of fully characterized homoleptic alkynyl bismuth compounds Bi(C≡CR)3 is presented. Facile homolytic Bi–C bond cleavage grants access to alkynyl radicals, which have been employed in selective C–X bond formation (X = C, B, Se, Te). This complements existing strategies for alkynyl radical generation as it proceeds under mild and purely ...

Blue and NIR Upconversion in Tm3+/Yb3+ Co‐Doped Yttrium Pyrogermanate Phosphor for High‐Sensitivity Optical Thermometry

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
Y2Ge2O7:Tm3+/Yb3+ phosphors synthesized via solid‐state method exhibit efficient blue and NIR upconversion luminescence under 980 nm excitation, enabled by cooperative energy transfer from Yb3+ to Tm3+. The system demonstrates excellent optical thermometry performance, achieving a maximum absolute sensitivity of 156.42 × 10−2 K−1 and relative ...

Possible Peierls Distortion Through Re2 Dimer Formation in the LaNiO2‐Type Nitrides LnReN2 (Ln = Pr, Nd)

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
This study presents the high‐pressure synthesis of two new anion‐vacancy‐ordered perovskite‐related nitrides, PrReN2 and NdReN2, featuring distorted LaNiO2‐type structures. X‐ray and neutron diffraction reveal a structural distortion driven by dimerization of Re‐chains, while electronic structure calculations reveal the simultaneous presence of ...

Leveraging 3d‐4f Coordination: Molecular Quantum Spring‐Magnet Behavior in Axial Ni2Ln Complexes

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
We report heterotrimetallic Ni2Ln complexes mimicking exchange spring magnets at the molecular level. CASSCF calculations show collinear anisotropy axes, while µSQUID studies reveal slow relaxation and open hysteresis in Ni2Tb, Ni2Dy, and Ni2Ho. Ferromagnetic 3d–4f coupling and anisotropy alignment enhance bistability, offering promise for quantum, and
