ChemPhysChem, Volume 27, Issue 8, 28 April 2026.The electrochemical dissolution of synthetic dolomite mixtures and reconstitution into hydroxide precursor phases suitable for Portland cement and Mg‐based cements is investigated. Adjustments of the experimental parameters during electrolysis allow for adjustments in product phase distribution, shedding insight into mixture separation techniques in ...

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

Eclipse radius measurements [PDF]
Methods for predicting the path edges and reducing observations of total solar eclipses for determining variations of the solar radius are described. Analyzed observations of the 1925 January eclipse show a 0.7 (arc second) decrease in the solar radius ...

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole‐Derived Squaraine
ChemPhysChem, Volume 27, Issue 7, 14 April 2026.Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...

Efficient and Durable Photochemical CO2 Reduction by TiO2‐Immobilized Metal Porphyrin Catalysts
ChemSusChem, Volume 19, Issue 7, 14 April 2026.A dye‐sensitized TiO2 scaffold bearing IrP and 3d‐metalloporphyrin catalysts (M‐TCPP; M = Fe, Co, Ni, Cu) drives efficient CO2‐to‐CO conversion and H2 evolution. Robust TiO2 immobilization and rapid interfacial electron transfer within the ternary architecture underpin the markedly enhanced activities relative to the mixed homogeneous systems.
