Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Unveiling a Young Thick Disk in the Milky Way

open access: yesThe Astrophysical Journal Letters
The thickness of a galaxy’s disk provides a valuable probe of its formation and evolution history. Observations of the Milky Way and local galaxies have revealed an ubiquitous disk structure with two distinctive components: an old thick disk and a ...

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Measuring Dust Masses of Protoplanetary Disks in Serpens and L1641/L1647 with ALMA

open access: yesThe Astrophysical Journal
Protoplanetary disks are an essential component of the planet formation process. The amount of dust and gas in the disk constrains the number and size of planets that can form in a system.

Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.

Electrochemically Driven Dissipative Growth of Affinity Hydrogels for Bioresponsive Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Voltage pulses drive the growth and reinforcement of hydrogel films under dissipative conditions. This biocompatible strategy enables efficient integration of affinity ligands into the hydrogel matrix, enhancing the selective capture of growth factors and allowing precise temporal control over their release, making them well‐suited as adaptive ...
