Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

Journal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Electrical Conductivity of Amorphous and Molten CaCO3 at High Pressures and Its Implications for Mantle Conductivity Anomalies

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Impedance spectrometry experiments have been conducted on CaCO3 up to 15 GPa and 2,100 K to identify its state under high pressure. The melting temperature of CaCO3 was also determined by the falling of a Re sphere observed via X‐ray radiography. The phase transition from aragonite to the amorphous phase does not cause a leap in the Electrical

Polyurethane Cascade Depolymerization by a Combination of Thermal Pretreatment and Enzymatic Hydrolysis

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...

Biocatalytic Epoxidation Pathway of Oils in Sponge‐Like Ionic Liquids Toward CO2‐Derived Cyclic Carbonate Synthesis

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
A sustainable chemo‐enzymatic synthesis of poly(cyclic carbonate)s from CO2 and renewable oils is reported for the first time using sponge‐like ionic liquids as reaction media by two sequential steps: epoxidation and CO2 cycloaddition. A sustainable chemo‐enzymatic synthesis of poly(cyclic carbonate)s from CO2 and renewable oils is reported for the ...
