High‐Resolution Mapping of Discharge Product in Li─O2 Batteries

open access: yesSmall Methods, EarlyView.
Li─O2 batteries promise exceptional energy density, but have several factors limiting performance, such as poor rate performance. To understand rate limitations, scanning electron microscopy with energy dispersive X‐ray spectroscopy and X‐ray nano‐computed tomography were employed to map the distribution of discharge products in discharged air ...

Clarity Without Credibility? Human Versus AI Abstracts in Otolaryngology

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective This study evaluated whether otolaryngologists can distinguish between human‐ and machine‐written abstracts. The primary question was whether large language models (LLMs) produce abstracts comparable in clarity and usefulness to human‐authored work, and whether reviewers can identify authorship with accuracy.

Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.

Subtracting Interferences in X‐Ray Spectra Obtained With Grating Spectrometers

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Higher order diffraction from surface contamination poses a major challenge for soft x‐ray spectral analysis using reflection zone plate spectrometers in electron probe microanalysis. We developed two correction methods applied to the Al L2,3 and Zn M2,3 emissions in AlZn60 alloy spectra: sequential overlay and subtraction of C Kα and O Kα ...
