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

Tailored Reconstruction of Polycrystalline CuO Nanorods Promotes C─C Coupling in CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the polycrystallinity of CuO nanorods enables directional reconstruction into rod‐like structures that stabilize Cu(OH)2 and increase Cu+ ratios, while modulating interfacial water dynamics to enhance C─C coupling and boost C2+ product formation in CO2 electroreduction.

Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...

Sequence and function of the two P domain potassium channels: implications of an emerging superfamily. [PDF]

open access: yes, 1998
A new superfamily of K+ channels has emerged in the past 2 years. Notable for possessing two pore-forming P domains in each subunit, members of the superfamily have been recognized through phylogeny from micro-organisms to humans. Four subfamilies of two

Role of Crosslinking and Backbone Segmental Dynamics on Ion Transport in Hydrated Anion‐Conducting Polyelectrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Thermally crosslinked poly(2‐vinylpyridine)‐based anion conducting polyelectrolytes have been synthesized. The segmental dynamics of these polyelectrolytes have been systematically modified by varying the degree of crosslinking. Both the experimental and simulation results indicate that segmental dynamics have a limited influence on ion transport in ...
