Evolution Mechanism of Interlayer Properties of CRTS III Slab Track during Construction

Applied Sciences
The interlayer properties of the CRTS III slab track during construction directly affect its long-term service condition. This article introduces time-varying coefficients that characterize the early properties of the interface between track slab and SCC

Toward Super‐Resolution Reconstruction of Diffusion–Relaxation MRI Using Slice Excitation With Random Overlap (SERO)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Diffusion MRI probes tissue microstructure, but low SNR and limited resolution hinder detection of features and parameter estimates. We introduce slice excitation with random overlap (SERO), which enables variable repetition times (TRs) and diffusion weighting within a single shot.

Mechanical behaviors of ballastless track under temperature and vehicle loads in high geo-temperature tunnel

Case Studies in Construction Materials
To explore the temperature field, temperature effect and mechanical behaviors of the track structure under combined load in high geo-temperature tunnel, the temperature field test platform is built to simulate the conditions under which the track bottom ...

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

Advanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

F‐Mediated Precise Control Over Amorphous/Crystalline Fe/Ni‐Based Phosphides Heterostructure for Efficient Oxygen Evolution Reaction

Rare Metals, EarlyView.
ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

The Hidden Costs of Coffee Production in the Eastern African Value Chains

Sustainable Development, EarlyView.
ABSTRACT There is increasing recognition that significant hidden costs associated with agrifood systems are not reflected in market prices. Coffee is among the three most traded agricultural commodities in the world and supports the livelihoods of more than 30 million smallholder households.

Boosting 2D Black Phosphorus Ambient Stability: Noncovalent Functionalization Using Viologen Molecules

Small, EarlyView.
Viologen derivatives are employed to tackle BPNS oxidation challenges through a noncovalent strategy. Comprehensive characterization techniques, complemented by DFT calculations, provide detailed insights into these interactions. Notably, XPS analysis reveals that MV‐BPNS hybrids experience minimal oxidation under ambient conditions, highlighting the ...

To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

Small Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging
