Praseodymium‐Modulated NiFe Layered Double Hydroxide with Enhanced Oxygen Evolution Activity and Extended Durability

Advanced Science, EarlyView.
Pr doping of NiFe‐LDH simultaneously tunes Ni 3d electronics and mesopore architecture. The optimized Ni2Fe0.88Pr0.12‐LDH switches the OER rate‐determining step, delivers 407 mV at 500 mA cm−2, and sustains 2190 h in half‐cell tests. An AEM electrolyzer with this anode operates over 1000 h at industrial current density, offering a durable rare‐earth ...

The influence of hypothetical exomoons on planetary thermal phase curves

Astronomy & Astrophysics
Context. More than 200 moons exist in our Solar System, yet no exomoon has been confirmed to date. While the innermost two planets of the Solar System lack natural satellites and most studies favour the existence of exomoons around long-period planets ...

Long‐Lifespan Polyorganosiloxane‐Based Silicone Evaporator for High‐Efficiency Seawater Desalination

Advanced Science, EarlyView.
Conventional evaporators suffer from salt crystallization and degradation. We design a white polyorganosiloxane evaporator with a reflector, achieving 4.344 kg m−2 h−1 at 1 sun in 3.5 wt.% NaCl. It shows over 53‑day cycling stability and 197‑day seawater resistance.

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.

Quenching Photo‐Induced Free Radicals Endows Superomniphobic Atmospheric Water Harvesting Hydrogels With UV Resistance for Durable Bifacial Photovoltaic Cooling

Advanced Science, EarlyView.
A hygroscopic hydrogel layer functionalized with fullerene C60 tackles heat and dust challenges in bifacial photovoltaics (PV) panels. It resists soiling and photo‐aging, maintains high transparency, absorbs water vapor from the air during the night, and delivers strong evaporative cooling power during daytime, significantly lowering PV panel ...

Enriched Soil Organic Carbon Underpins Long‐Term Stable Crop Productivity Across China's Croplands

Advanced Science, EarlyView.
Quantifying the nonlinear relationships and causal effects of soil organic carbon (SOC) on crop stability reveals specific critical thresholds and saturation points. This partitions the national SOC spectrum into three functional phases. Integrating these spatial delineations with high‐resolution maps of marginal gains pinpoints regions with the ...
