Article Abstract

Atomic force microscopy (AFM) is extensively applied to measure cell and tissue mechanics but lacks a standardized organoid stiffness assessment. Here, we present a protocol for quantifying the Young's modulus of organoids via AFM, combining force-curve analysis with an optimized probe. We describe steps for preparing organoids, OCT embedding, slicing, AFM detection, and force-curve analysis. By mechanically addressing gaps in organoids, this protocol improves reproducibility and expands the capabilities of biomechanical research.

The effects of pressure on the crystal structure of scheelite-type perrhenates were studied using synchrotron powder X-ray diffraction and density-functional theory. At ambient conditions, the studied materials AgReO, KReO, and RbReO, exhibit a tetragonal scheelite-type crystal structure described by space group 4/. Under compression, a transition from scheelite-to-M'-fergusonite (space group 2/) was observed at 1.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.

Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.

Li-metal batteries promise ultrahigh energy density, but their application is limited by Li-dendrite growth. Theoretically, fluorine-containing anions such as bis(fluorosulfonyl)imide (FSI) in electrolytes can be reduced to form LiF-rich solid-electrolyte interphases (SEIs) with high Young's modulus and ionic conductivity that can suppress dendrites. However, the anions migrate toward the cathode during the charging process, accompanied by a decrease in the concentration of interfacial anions near the anode surface.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.

Hemostatic intervention at the bleeding site during early-phase wound management plays a crucial role in reducing trauma-induced complications and mortality, while advanced wound dressings facilitate hemorrhage control, exudate management, and antimicrobial protection to promote optimal healing outcomes. To address these issues, we developed a multifunctional collagen/silk fibroin/Mg(OH)₂ (Col/SF/Mg(OH)₂) composite sponge combining enhanced mechanical strength, rapid hemostasis, and broad-spectrum antibacterial activity. The incorporation of silk fibroin (SF) through covalent crosslinking increased the elastic modulus by 4.
