Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

Advanced Energy Materials, Volume 16, Issue 4, 28 January 2026.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.

Hot, Cold, and Multicomponent Accretion Flows around Supermassive Black Hole Binaries

The Astrophysical Journal
We develop a model for supermassive black hole binaries (SMBHBs) accreting below their Eddington limit, focusing on systems where hot, advection-dominated flows become viable.

Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.

Using Faded Changing-look Quasars to Unveil the Spectral Energy Distribution Evolution of Low-luminosity Active Galactic Nuclei

The Astrophysical Journal
The structure of accretion flows in low-luminosity active galactic nuclei (AGNs) at low Eddington ratios (∼10 ^−2 –10 ^−3 ) are poorly understood, and can be probed using the spectral energy distributions (SEDs) of faded changing-look (CL) quasars ...

Subgrain and Cavity Development during Creep of Al‐3.85%Mg

Advanced Engineering Materials, Volume 27, Issue 23, December 2025.
Al‐3.85%Mg does form subgrains if crept at very high strains. This fact allows the unification of the creep description in two different alloys such as pure Al and Al–Mg alloys. It is classically considered that the creep mechanisms for type M (e.g., pure Al) and type A alloys (e.g., Al–Mg alloys) are different.

Millikelvin Intracellular Nanothermometry with Nanodiamonds

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Nanothermometry in living cells is crucial for understanding heat diffusion and advancing cellular biology and drug discovery. Previous studies have reported controversial intracellular temperature variations. Using nanodiamond nanothermometry in macrophages, it is found that, in such experimental setting, apparent temperature changes are actually due ...

A New Classification of In Situ and Anvil Cirrus Clouds Uncovers Their Properties and Interhemispheric Connections

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract The challenge of distinguishing convective anvil cirrus from in situ cirrus has long limited the quantification of their distinct roles in regulating upper‐tropospheric moisture and modulating Earth's energy budget. In this study, we address this ambiguity by introducing a physically constrained classification framework that applies advanced ...

Palagonitization of Volcanic Rocks in Polar Climates: The Case of Deception Island (Antarctica)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract A detailed study of palagonitization in rocks from Deception Island—one of Antarctica's most active volcanoes—has been performed to advance our understanding of this alteration process. A detailed petrographic (optical and SEM), mineralogical (XRD), and mineral and glass spot geochemistry (EDS and EMP) characterization has been conducted on ...
