Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

open access: yesAdvanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Advancing the Co‐Based Anode Catalysts Using Ionomers in Pure‐Water Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
The role of ionomers is investigated in advancing cobalt‐based oxygen evolution catalysts in pure‐water anion exchange membrane electrolysers. Using in situ electrochemical analysis, ex situ material characterization, and membrane potential sensing, it is observed surface reconstruction at high currents and mitigated it via ionomer coating, achieving ...

Resting State Functional Connectivity Patterns Associate with Alcohol Use Disorder Characteristics: Insights from the Triple Network Model [PDF]

open access: yesarXiv
Prolonged alcohol use results in neuroadaptations that mark more severe and treatment-resistant alcohol use. The goal of this study was to identify functional connectivity brain patterns underlying Alcohol Use Disorder (AUD)-related characteristics in fifty-five adults (31 female) who endorsed heavy alcohol use.

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

open access: yesAdvanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...
