Visualizing and Quantifying Indentation‐Induced Densification and Cracking in Vitreous Silica

open access: yesSmall, EarlyView.
A nanofocus X‐ray scattering method maps how vitreous silica densifies and cracks in situ beneath a sharp indenter. Spatially resolved structural measurements reveal the evolving temporary and permanent densification zones, together with load‐dependent crack formation.

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

open access: yesSmart Molecules, EarlyView.
MOFs offer high porosity and tunability for biomedical applications, especially in cancer therapy via ROS generation and targeted delivery. Though toxicity, stability, and scalability remain key clinical challenges. Drug loading in MOFs exceeds 60%–70% with controlled release behavior.

Effect of Vacancy Defect on Mechanical Properties of Single Wall Carbon Nanotube

open access: yesApplied Nano
Carbon nanotubes (CNTs) are cylindrical nanostructures formed by rolling a graphene sheet—a hexagonal lattice of carbon atoms—into a tube. Based on the rolling direction, CNTs are categorized as armchair, zigzag, or chiral.

Rubber‐Glass‐Crystal Triple Phase Transition in Polyacrylamide Hydrogels and Environment‐Adaptive Shape Memory Effect

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 21, 6 November 2026.
By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

Coarse‐Grained Molecular Dynamics and Persistent Homology Analysis of Crosslinker Effects on Polymer‐Film Deformation

open access: yesMacromolecular Theory and Simulations, Volume 35, Issue 6, November 2026.
The crosslinking effect of polymer films on mechanical properties has been studied using coarse‐grained molecular dynamics simulations. Persistent homology analysis captures the characteristic ring structure for crosslinking agents and their stretching behavior during tensile deformation, showing the effectiveness of persistent homology analysis as a ...
