Enabling Singlet Fission Exothermicity by Tuning the Solvent in a High Energy Triplet Formyl‐Fluorene Derivative

ChemPhotoChem, Volume 10, Issue 8, August 2026.
Solvent polarity/viscosity coupled with the concentration effect on the INTRA + INTERmolecular singlet fission of a formyl‐fluorene derivative are explored by ultrafast spectroscopy. Small changes in solvent dielectric constant/polarizability are very effective in modulating the S1‐1TT energy gap pointing to a slightly endothermic SF in toluene and ...

Kinetic Control of Crystal Polymorphism via Flash Photonic Heating: Reversible α ↔ β‐Bi2O3 Phase Cycling in Thin‐Film Photoelectrodes

Small Structures, Volume 7, Issue 8, August 2026.
Flash photonic heating achieves unprecedented heating rates of 106–107 °C/s, enabling kinetic control of bismuth oxide polymorphism on FTO–glass substrates. Ultrafast thermal pulses drive melt‐recrystallization pathways that kinetically trap metastable β‐Bi2O3, while conventional processing yields thermodynamically stable α‐Bi2O3.

Decoding Superconductivity in La3Ni2O7−δ Thin Films via Ozone‐Driven Structure and Oxidation Tuning

Small Structures, Volume 7, Issue 8, August 2026.
We demonstrate that superconductivity in La3Ni2O7‐δ thin films correlate with the LNO‐2222 polytype, which must extend coherently across the layer. Conversely, the LNO‐1313 phase disrupts superconductivity, as confirmed by recent studies. Our work highlights the need to stabilize the 2222 phase through optimized growth to achieve robust and ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Petrogenesis and Tectonic Evolution of Cenozoic Magmatism in the Southernmost Northern Andes: Insights From Zircon Petrochronology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study integrates new zircon U–Pb ages, zircon εHf(t)–δ18O isotopic data, and whole‐rock geochemistry to refine the temporal and spatial framework of magmatism in the southern Northern Andes (SNA) from ∼65 to 6 Ma. The San Lucas, Catamayo, Portachuela, and Gonzanamá batholiths and magmatic suites, along with Late Miocene plutons, display ...

Vanadium Isotopic Compositions of the High‐3He/4He Baffin Island Lavas

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The isotopic composition of vanadium (V) in hotspot lavas provides new insight into the source of deep mantle heterogeneities. We measured V isotopic compositions in Paleogene Baffin Island lavas, which erupted above the Iceland plume head, to constrain the mantle plume source. These lavas have V isotopic compositions that are lighter (−0.96 ±

Distinct Transcrustal Evolutions of Komatiitic Primitive Magma: Implications for the Compositional Dichotomy of Continental Flood Basalts

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The origin of the compositional dichotomy between high‐Ti and low‐Ti basalts in continental flood basalt provinces remains debated. Most existing studies attribute this dichotomy directly to variations in primitive magma composition to circumvent the complexities of significant evolutionary processes, such as multiphase fractional ...
