Directional Liquid Transport Enabled pH‐Responsive Hierarchical Composite for Enhanced Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
A hierarchical composite with a gradient architecture transitioning from hydrophobic to hydrophilic layers integrates diode‐like liquid transport, efficient water absorption, breathability, and mechanical robustness. This device enables a multifunctional therapeutic platform with pH‐responsive dual‐drug release, providing synergistic anti‐inflammatory ...

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Resolving the Structural Duality of Graphene Grain Boundaries

open access: yesAdvanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Evaluation of the time–temperature superposition by comparing neat and glass-fibre-reinforced epoxy using dynamic mechanical thermal analysis

open access: yesPolymer Testing
Dynamic mechanical thermal analysis is a well-established method to determine the influence of temperature and frequencies on polymers. One challenge inherent to this method is the potential for significant changes in material properties, which can ...

Self‐Cooling Molecular Spin Qudits

open access: yesAdvanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.
