3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

Advanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

Advanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

Ion‑Mediated Structural Engineering of Hydrogel Interfaces for Tunable Mechanical and Analyte Diffusion Properties in Electrochemical Biosensors

Advanced Materials, EarlyView.
An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...

Electrically Assisted Thermal Stamping of Tunable Carbon‐Based Nanofilms for Direct Fabrication of Hydrophobic, Energy Harvesting, and Sensing Devices

Advanced Materials, EarlyView.
Schematic illustration of the electrically assisted thermal stamping (EATS) method for direct fabrication of carbon‐based nanofilms and their multifunctional applications. Localized Joule heating triggers simultaneous exfoliation, reduction, and fluoropolymer incorporation under ambient conditions, yielding tunable carbon‐based thin‐film coatings ...

Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

Advanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

Ownership and Control in Outsourcing to China: Estimating the Property-Rights Theory of the Firm [PDF]

In this paper, we develop a simple model of international outsourcing and apply it to processing trade in China. We observe China's processing exports broken down by who owns the plant and by who controls the inputs the plant processes.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.
