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

open access: yesJournal 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 ...

Influence of Rare Earth Elements on Prebiotic Reaction Networks Resembling the Biologically Relevant Krebs Cycle

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Rare earth elements can act as mediators in a prebiotic reaction network, producing various intermediates of the citric acid cycle starting from glyoxylate and pyruvate. The ionic radius and the resulting variation in Lewis acidity has a significant influence on the observed product scope.

Coupled Experimental Study and Thermodynamic Modeling of GeO2 and GeO2–CaO and GeO2–SiO2 Binary Systems

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Mono‐Materials Created by Engineering a Continuum of P3HB Stereomicrostructures in a One‐Step Catalytic Process

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
Diastereomeric mixtures of diolide were polymerized to P3HB mono‐materials that behave like thermoplastics, thermoplastic elastomers, and pressure‐sensitive adhesives, which were then combined to create all‐P3HB mono‐material tapes. Abstract Multi‐material products that combine multiple complementary polymers can create products with desired ...

Evaluation of shear bond strength based on substructure materials and ceramic veneering techniques

open access: yesJournal of Prosthodontics, Volume 35, Issue 2, Page 160-168, February 2026.
Abstract Purpose Bilayered restorations have both the strength of the substructure material and the esthetics of the veneer material; however, they should have appropriate bonding between the two materials. This study aimed to evaluate the shear bond strength (SBS) according to the substructure material and veneering technique used in bilayered ...
