Optically‐Coupled X‐Ray Computed Laminography System for High‐Speed Inspection of Lithium‐Ion Batteries

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
This study presents an optically coupled X‐ray computed laminography system for high‐speed inspection of lithium‐ion batteries. A scintillator serving as a virtual detector decouples spatial resolution from the X‐ray focal spot size, enabling defect detection even with large‐spot, high‐power X‐ray tubes.

Optimized reconstruction of undersampled Dixon sequences using new memory‐efficient unrolled deep neural networks: HalfVarNet and HalfDIRCN

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1189-1204, February 2026.
Abstract Purpose Fat fraction (FF) quantification in individual muscles using quantitative MRI is of major importance for monitoring disease progression and assessing disease severity in neuromuscular diseases. Undersampling of MRI acquisitions is commonly used to reduce scanning time. The present paper introduces novel unrolled neural networks for the

Novel Insights on Ocean Internal Waves: Quantitative Surface Manifestations and Upper Ocean Layer Displacements From the Surface Water Ocean Topography Mission (SWOT) Measurements

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

Large‐Scale Flow Toward Low‐Velocity Anomalies Reconciles Seismic and Geodynamic Constraints in the Deepest Mantle Beneath Alaska

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Deep mantle downwellings are typically located away from the two Large Low‐Velocity Provinces (LLVPs) in Earth's mantle. Geodynamic models based on global seismic tomography generally predict that convective flow at the core‐mantle boundary spreads laterally away from downwelling regions and toward LLVPs.

Investigation of the printability of ethyl 2‐[4‐(1,3,4‐oxadiazol‐2(3H)‐thion‐5‐yl)phenylhydrazono]‐3‐oxobutyrate on coated and uncoated papers

open access: yesColoration Technology, Volume 142, Issue 1, Page 67-74, February 2026.
Abstract There is a growing demand in the printing industry for pigment‐based inks with excellent lightfastness and rub resistance qualities. In this work, a novel ink with the formulation ethyl 2‐[4‐(1,3,4‐oxadiazole‐2(3H)‐thione‐5‐yl)phenylhydrazono]‐3‐oxobutyrate (OXKT) was prepared as a pigment and its printability was investigated for use in ...

Generalized Surface Conductivity Model for Anisotropic Phonon Polaritons in van der Waals Slabs

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
Herein, we report a generalized surface conductivity model which includes all waveguide polariton branches, by taking into account the out‐of‐plane dimension. Using this generalized 2D model can separate and examine each individual polaritonic mode in van der Waals slabs and further clarify their contributions in near‐field light matter interactions ...

An Epsilon‐Near‐Zero‐Based Nonlinear Platform for Ultrafast Re‐Writable Holography

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
We show that an unstructured, sub‐wavelength thick epsilon‐near‐zero material, such as ITO, can be efficiently used for ultrafast re‐writable holography over a broad bandwidth range. We showcase two powerful applications of our scheme, that is, spatial structuring of light and optical computation.

Water‐Induced Local Redox Reactions on Individual Ti3C2Tx MXene Flakes in Aqueous Environment

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
The local chemistry of individual Ti3C2Tx MXene flakes and confined water are investigated by in situ Scanning Transmission X‐ray Microscopy (STXM) in aqueous environment. We reveal water‐induced redox reactions non‐uniformly distributed over the MXene flakes upon sequential exposure to acidic and neutral aqueous solution containing alkali cations ...
