Unlocking Energy Potential: Exploiting Anionic Redox Activity in Na‐Based Layered Oxides

Small, Volume 22, Issue 33, 12 June 2026.
Anionic redox in Na‐based layered oxide cathodes unlocks additional capacity beyond conventional transition‐metal redox limits, enabling high‐energy sodium‐ion batteries. This review elucidates coupled cationicanionic redox mechanisms across P2‐, O3‐, and related structural phases, while critically addressing key challenges such as voltage hysteresis ...

Low‐Dose Electron Total Scattering Analysis Resolves Non‐Crystalline Phase Separation in Polymer Semiconductors and Device Multilayers

Small Methods, Volume 10, Issue 11, 8 June 2026.
The performance of polymer blend semiconductors is governed by both the degree of phase separation and crystallization, but these two aspects have remained unresolved. We report methods for mapping amorphous‐amorphous as well as amorphous‐crystalline phase separation in polyfluorene‐based polymer blends using spatially resolved nanobeam electron total ...

Laser‐Etched Microgroove Structure Induces Superhydrophobic Transition of Electrode Surface to Promote Efficient Reduction of CO2 to Multicarbons at High Current Density

Small Structures, Volume 7, Issue 6, June 2026.
We employ high‐power laser etching to construct a superhydrophobic Cu2O electrode, enabling systematic interrogation of the microenvironment‐activity relationship.This work establishes a framework for tailoring gas diffusion electrode architectures to directionally modulate the CO2RR microenvironment, offering new routes to enhance selectivity and ...

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1851-1866, June 2026.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...
