ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 6, November 2025.We use AI‐enhanced intensity modulation two‐photon excited fluorescence microscopy (ml‐IM2PM) to investigate defect properties and charge carrier recombination in MAPbBr3 films. Mapping exciton generation rate, trap concentration, and trap energy barriers and correlating spatially resolved charge carrier recombination pathways, we identify the ...

Fast Tissue Clearing and Volume Imaging Techniques for Anatomy
Microscopy Research and Technique, Volume 88, Issue 11, Page 2851-2864, November 2025.Tissue clearing and volume imaging techniques have revolutionized our ability to visualize large biological samples, but they face obstacles related to speed, tissue preservation, complexity, and the need for fluorescence labels that make them difficult to implement in anatomy and preclinical research.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.ABSTRACT In this paper, we numerically examine the precision challenges that emerge in automatic differentiation and numerical integration in various tasks now tackled by physics‐informed neural networks (PINNs). Specifically, we illustrate how ill‐posed problems or inaccurately computed functions can cause serious precision issues in differentiation ...

Rapid Communications in Mass Spectrometry, Volume 39, Issue 19, 15 October 2025.ABSTRACT Rationale Aromatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs) pose significant risks to human health and the environment due to their toxic and carcinogenic properties. These depend strongly on molecular structure, with even isomers exhibiting different characteristics.

Extensive TDDFT Benchmark Study of the Resonance Raman Spectra of Lumiflavin
Journal of Computational Chemistry, Volume 46, Issue 26, October 5, 2025.An extensive computational TDDFT resonance Raman study of lumiflavin is presented including forty‐two different DFT functionals, benchmarked against the experimental spectra of FMN. The inclusion of resonance enhancements improved the agreement for most functionals.

Advanced Functional Materials, Volume 35, Issue 40, October 1, 2025.The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.

Standalone Integrated Magnonic Devices
Advanced Materials, Volume 37, Issue 40, October 9, 2025.A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

Nonlinear Optical Properties of Mono and Multilayer MoWSe2 Alloys
Advanced Optical Materials, Volume 13, Issue 29, October 13, 2025.We employ second‐harmonic generation and two‐photon photoluminescence to probe the excitonic resonances and exciton binding energy in Mo(1x)WxSe2 alloys as a function of composition and layer number. Our work lays the groundwork for understanding the optical and electronic properties of TMD alloys, a crucial step toward next‐generation optoelectronic ...
