Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

3D Hydrodynamic Flow Lithography

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Causal association between periodontitis and oral cancer: a two-sample Mendelian randomization study

open access: yesDiscover Oncology
Objectives Reports suggest an association between periodontitis and oral cancer. Therefore, this study used a Mendelian randomisation analysis to investigate whether a causal relationship exists between periodontitis and oral cancer and whether ...

Confinement‐Engineered Thermally Programmed Ion‐Gating Separator for Decoupling Thermal–Electrochemical Feedback in High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A new phase‐change material encapsulated membrane offers more thermal resilience stability and safety than the conventional separators for batteries. ABSTRACT Thermal runaway in lithium‐ion batteries arises from the intrinsic coupling between heat generation and ion transport, yet conventional shutdown separators primarily rely on passive pore collapse
