Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Facile Tri‐Metallic Catalyst Fabrication Using the Dynamic Hydrogen Bubble Template method

open access: yesAdvanced Functional Materials, EarlyView.
Porous metal catalysts are prepared using hydrogen bubbles as a natural template. By carefully selecting metal combinations and thermal treatment, the researchers tailored surface composition and structure, boosting catalytic performance. The approach offers a powerful and flexible route to designing advanced materials for green energy Abstract ...

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

open access: yesAdvanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Oxygen Evolution Reaction by Ni‐Hexacyanoferrates Nanocubes Integrated with Trigonal Selenium: Effect, Properties and Performances

open access: yesAdvanced Functional Materials, EarlyView.
This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

Industrial Property Institutions, Patenting, and Technology Investment in Spain and Mexico, c. 1820-1914. [PDF]

open access: yes
This paper explores the nature and implications of nineteenth century patent law in two late-industrializing countries: Spain and Mexico. Both inherited earlier ancien regime monopoly practices, both adopted aspects of modern, codified patent systems in ...

Microstructural Evolution Dominates the Changes in the Thermal Conductivity of Conjugated Polymers Upon Doping

open access: yesAdvanced Functional Materials, EarlyView.
The relationship between the doping induced microstructure and thermal conductivity changes is elucidated for conjugated polymers. Eight conjugated polymers with different doping systems are studied, showing varied thermal conductivity responses based on structural order.
