Comparative Analysis of Work Function Measurement Techniques Based on Scanning Probe Microscopy
Advanced Materials, EarlyView.Non‐contact scanning probe microscopy visualizes the surface topography based on surface electronic properties. The tunneling current, which defines the geometry of the tunnel–junction, has to overcome the effective surface work function barrier to reach the probe from the surface.

Uniform approximation of eigenvalues in Laguerre and Hermite beta-ensembles by roots of orthogonal polynomials [PDF]
We derive strong uniform approximations for the eigenvalues in general Laguerre and Hermite beta-ensembles by showing that the maximal discrepancy between the suitably scaled eigenvalues and roots of orthogonal polynomials converges almost surely to zero

Recent Advances in Ferrite‐Based Materials for Biomedical Applications: A Comprehensive Review
Advanced Materials, EarlyView.Ferrite nanoplatforms are presented as tunable biomedical materials in which synthesis control, cation engineering, defect/morphology regulation, and surface functionalization govern structure–property–bioactivity relationships. These design strategies enable multifunctional applications including MRI contrast, magnetic hyperthermia, targeted drug ...

Operation Limits of Integrated Photo‐Rechargeable Batteries
Advanced Materials, EarlyView.This study elucidates the operational limitations of integrated photo‐rechargeable batteries. We demonstrate that the photo‐charging process is fundamentally restricted not only by material‐to‐material energy level alignment but also by transient capacitive charge accumulation within the cathode framework.

Almost sure convergence of a class of stochastic algorithms [PDF]
In this paper, we establish the almost sure convergence of d-valued sequences generated by a particular class of stochastic algorithms and we apply this result to a stochastic approximation type EM algorithm for the mixture problem.Monte Carlo EM ...

A Hybrid Computational Framework for PCF‐based SPR Sensor With Machine Learning and xAI
Advanced Materials Interfaces, EarlyView.A photonic crystal fiber‐based surface plasmon resonance (SPR) sensor integrating rectangular air holes along with conventional circular air holes achieves exceptional wavelength sensitivity of 15,000 nm/RIU across a broad refractive index range of 1.31–1.39. Integrated machine learning with explainable AI (xAI) models achieves high prediction accuracy

Almost sure convergence of Titterington's recursive estimator for mixture models [PDF]
Titterington proposed a recursive parameter estimation algorithm for finite mixture models. However, due to the well known problem of singularities and multiple maximum, minimum and saddle points that are possible on the likelihood surfaces, convergence ...

Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth
Advanced Materials Interfaces, EarlyView.Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...
