Dual‐Site Ru Single‐Atoms and RuP Nanoclusters on N, P, and B Co‐Doped Porous Carbon for Efficient Alkaline HER and AEM Water Electrolysis

Advanced Functional Materials, EarlyView.
Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Colloidal Silica-Stabilized Subgrade for Self-Sensing Vehicle Stress Affected by Unsaturation and Crack

Journal of Marine Science and Engineering
Colloidal silica can seep through calcareous sand in the subgrade, forming colloidal-silica-cemented sand with self-sensing ability—that is, it is sensitive to stress changes caused by vehicle loading.

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

Advanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Time-dependent universal conductance fluctuations in mesoscopic Au wires: implications

, 2007
In cold, mesoscopic conductors, two-level fluctuators lead to time-dependent universal conductance fluctuations (TDUCF) manifested as $1/f$ noise. In Au nanowires, we measure the magnetic field dependence of TDUCF, weak localization (WL), and magnetic ...

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Influence of Phosphoramidites in Copper-Catalyzed Conjugate Borylation Reaction [PDF]

, 2012
Copper(I) has become the preferred metal to catalyze the β-boration of α,β-unsaturated carbonyl compounds, and now we demonstrate that easily accessible monodentate chiral ligands, such as phosphoramidites and phosphites, can be convenient alternative ...

Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

Advanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

Back Analysis of Rainfall-Induced Landslide in Cimanggung District of Sumedang Regency in West Java Using Deterministic and Probabilistic Analyses

Geosciences
Rainfall-induced landslides are widespread in Indonesia, particularly in West Java, where volcanic residual soils are typically stable but may become unstable during heavy rainfall. This study aims to back analyze the geotechnical factors contributing to
