Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Enhancing the Photocatalytic Performance of Carbon Nitrides Through Controlled Local Structure Modification

open access: yesAdvanced Functional Materials, EarlyView.
This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

Catalytic TiO2 with Self‐Assembled Monolayer for Highly Sensitive, Selective, and Non‐Invasive Monitoring of Sweat L‐Cysteine

open access: yesAdvanced Functional Materials, EarlyView.
A self‐assembled monolayer of 3‐mercaptopropyltrimethoxysilane (MPTS) molecular receptor and titanium oxide‐modified carbon cloth (MPTS/TiO2/CC) was synthesized for the specific detection of sweat L‐cysteine, which is associated with the precision neutrition, cardiovascular system and neuro system.

Supramolecular Liquid Crystal Elastomer Adhesives: Role of Internal Damping and Hydrogen Bonding

open access: yesAdvanced Functional Materials, EarlyView.
The adhesion strength can be significantly enhanced through the molecular design of supramolecular liquid crystal elastomers (LCEs) that combine high internal damping from mesogen reorientation with abundant hydrogen‐bonding moieties. Solvent vapor annealing enables reversible, non‐thermal control of adhesion, offering potential for heat‐sensitive ...

Unveiling Phonon Contributions to Thermal Conductivity and the Applicability of the Wiedemann—Franz Law in Ruthenium and Tungsten Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.
