Defined Matrices Reveal Epithelial‐ and Mesenchymal‐Specific Responses to Stiffness and Adhesion in Human iPSC‐Derived Intestinal Organoids

Advanced Materials, EarlyView.
Defined PEG hydrogels enable human iPSC‐derived intestinal organoid culture without Matrigel. PEG‐ and Matrigel‐cultured organoids both support duodenal‐like epithelial identity, but direct comparison reveals subtle epithelial differentiation‐marker shifts and stronger mesenchymal ECM‐remodeling/integrin programs in PEG.

Experimental and Numerical Study on Dynamic Response of PVC Foam Sandwich Beams Under Ice Impact

Journal of Marine Science and Engineering
This paper mainly investigates the ice-impact resistance of PVC foam sandwich beams for polar ship protective structures through low-velocity impact experiments and nonlinear finite element simulations. An experimentally validated elastic–plastic coupled

An Engineered Thio‐Amino Polymer Achieves Potent, Safe, and Broad Cell Type Delivery in the Lung Mapped by Spatial Transcriptomics

Advanced Materials, EarlyView.
Synthesis and screening of a polymer library produced a versatile and inhalable mRNA vehicle for the lungs (P81). Compared to a published LNP, P81 provides increased delivery efficacy, achieving widespread expression in broad cell types, with no toxicity.

Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

Advanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

Advanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.
