High‐Entropy Ceramic‐Enhanced Deformable Triboelectric Nanogenerator for Noncontact Biomechanical and Raindrop Energy Harvesting

Advanced Materials, EarlyView.
A large‐area, deformable high‐entropy‐ceramic (HEC)‐doped triboelectric nanogenerator with a trilayer architecture is developed, consisting of an HEC‐doped triboelectric layer, a graphite‐like textile charge‐storage layer, and stretchable carbon black electrodes.

Mechanistically Interpretable Artificial Intelligence for Designing Oxygen Electrocatalysts

Advanced Materials, EarlyView.
Mechanistically interpretable artificial intelligence screens nearly seven million perovskite compositions and identifies key descriptors—d‐p hybridization and densification resistance—that govern oxygen electrocatalysis. The discovered BaCo0.8Nb0.1Zr0.1O3‐δ achieves a record 2.68 W cm−2 peak power density at 600°C with over 500 h of durable operation ...

Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

Advanced Materials, EarlyView.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

Advanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Estimating the cross-sectional sizes of potential solar triggers of near-Sun magnetic switchbacks

Astronomy & Astrophysics
Context. The discovery of near-Sun magnetic switchbacks (SBs) represents a key result of the Parker Solar Probe (PSP) mission. Aims. Several theories and models suggest that near-Sun SBs may be triggered by small-scale transient phenomena occurring in ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

X-class Flare on 2023 December 31 Observed by the Solar Ultraviolet Imaging Telescope on Board Aditya-L1

The Astrophysical Journal Letters
We present the multiwavelength study of the ejection of a plasma blob from the limb flare SOL2023-12-31T21:36:00 from NOAA 13536 observed by the Solar Ultraviolet Imaging Telescope (SUIT) on board Aditya-L1. We use SUIT observations along with those from

Radiation‐Matter Interaction in Chemical Vapor Deposition‐Grown Two‐Dimensional Tungsten Disulfide

Advanced Materials Interfaces, EarlyView.
Gamma irradiation tunes the magnetic properties of CVD‐grown WS2 material. Moderate irradiation doses induce low‐temperature ferromagnetic‐like behavior, whereas higher doses suppress the magnetic response because of increased defect formation. These findings provide insight into defect‐mediated magnetism in 2D TMDs and could be relevant to future ...

Unveiling the True Nature of Plasma Dynamics from the Reference Frame of a Superpenumbral Fibril

The Astrophysical Journal
The magnetic geometry of the solar atmosphere, combined with projection effects, makes it difficult to accurately map the propagation of ubiquitous waves in fibrillar structures.
