3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Ionospheric effects of the extreme solar activity of February 1986 [PDF]

open access: yes
During February 1986, near the minimum of the 11 year Solar sunspot cycle, after a long period of totally quiet solar activity (R sub z = 0 on most days in January) a period of a suddenly enhanced solar activity occurred in the minimum between solar ...

Scalable Solar Evaporator Based on Bandgap Engineered CuMnCrO4 Spinel Oxide with Salt‐Resistant Property for Contaminated Seawater

open access: yesAdvanced Materials, EarlyView.
Incorporating multiple cations (Cu2⁺ and Cr3⁺) into the Mn3O4 spinel lattice strategically tunes the electronic structure, narrowing the bandgap from 2.3 to 1.49 eV. This enhances visible–NIR light absorption and photothermal conversion, enabling a high water evaporation rate of 4.1 kg m−2 h−1 under 1 sun.

Photoresponsive Adaptive Reconfiguration of Single‐Atom Interface With Intermittent Light and Soft Ionic Lattices

open access: yesAdvanced Materials, EarlyView.
We present a photoresponsive platform that integrates SACs with halide perovskite supports, turning perovskite ion mobility, typically a stability concern, into a functional mechanism for light‐regulated self‐repair and reversible atomic reconfiguration. Adaptive metal‐support interactions are established through bandgap‐funnel engineering and the soft

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

open access: yesAdvanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Dynamics of Subsurface Flows in Solar Active Regions during the 2024 May Storm

open access: yesThe Astrophysical Journal
In 2024 May, the Sun exhibited intense magnetic activity, marked by numerous high-intensity flares resulting from the interaction and merging of NOAA active regions (ARs) 13664 and 13668 in the southern hemisphere and AR 13663 in the northern hemisphere.
