Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Drying‐Driven Microstructural Reorganization as a Key Origin of Rate Limitation in Multi‐Walled Carbon Nanotube‐Based Thick Electrodes for Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study shows drying‐driven microstructural reorganization as a key origin of rate limitations in multi‐walled carbon nanotubes (MWCNT)‐based thick electrodes. By decoupling transport properties, the work reveals that rapid evaporation can amplify thickness‐dependent CNT agglomeration, generating coupled electronic and ionic bottlenecks. Importantly,

Triboelectric nanogenerators for vehicle intelligent cockpits

FlexMat, EarlyView.
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

The Orbital Evolution of Planet-Disk Solar Systems. [PDF]

, 2008
The extrasolar planets discovered to date possess larger eccentricities and smaller semi-major axes than similar planets in our solar system. It is not thought possible for these planets to form in situ; we propose they result from a combination of ...

Recent advances and clinical applications of 3D printing for female reproductive organ regeneration and gynecological disease

Interdisciplinary Medicine, EarlyView.
This comprehensive review highlights the transformative role of 3D printing and bioprinting technologies in the regeneration of female reproductive organs and the treatment of gynecological diseases. Unlike previous overviews that focus narrowly on isolated applications, this work provides an integrative analysis of recent clinical and preclinical ...

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

A Bridge between Young Stars Formed by Gravitational Interaction

The Astrophysical Journal Letters
The majority of stars are born in clustered environments. In these environments, close encounters between young stars with planet-forming disks are expected to occur frequently. However, direct evidence of such interactions remains rare.
