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

Advanced 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 ...

Ultrastructural visualization of the transmembranous and cytomatrix-related part of nicotinic acetylcholine receptor of frog motor endplate by means of an immunochemical avidity of IgG for d-tubocurarine.

Folia Histochemica et Cytobiologica, 2008
In the present study, a fine ultrastructural localization of nicotinic acetylcholine receptor (nAChR) was attempted, using d-tubocurarine (d-TC), a quaternary ammonium compound binding to nAChR.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

Advanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans).

Perovskite Light‐Emitting Diodes with Quantum Wires and Nanorods

Advanced Materials, EarlyView.
This review focuses on low‐dimensional perovskite materials and discusses their applications in light‐emitting diodes (LEDs). Special attention is given to the introduction of perovskite quantum wires and nanorods, two unique types of one‐dimensional (1D) materials, and their interesting optoelectronic properties.

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]

, 2017
Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...
