Potentiation of acetylcholinesterase by a series of quaternary ammonium compounds

Journal of Pharmacy and Pharmacology, 1968
Abstract Eleven spiran, and two non-spiran, quaternary ammonium compounds have been examined and some of these compounds found to potentiate the hydrolysis of acetylcholine by acetylcholinesterase at high substrate concentrations. The experiments were made in three reaction media, each differing in its ionic composition.

Tailoring the Solid Electrolyte Interphase Composition on Lithium Metal Anodes by the Choice of Ionic Liquid during Mechanochemical Modification

Advanced Materials Interfaces, EarlyView.
Roll‐pressing lithium foil in contact with ionic liquids is used to produce modified lithium anodes. The differences in performance, composition, and evolution upon cycling of the anodes depending on the ionic liquid used are highlighted, when used in combination with a classical Li‐ion electrolyte.

Effective Molecular Alignment of Semiconducting Polymer and Its Application to Photopatterned Stretchable Transistors

Advanced Materials Technologies, EarlyView.
Excellent mobility is achieved in intrinsically stretchable, fine‐patterned organic thin‐film transistors (OTFTs) through well‐aligned molecular arrangements. Abstract Intrinsically stretchable organic transistors are promising solutions for realizing stretchable electronic systems, such as skin‐like wearables and next‐generation displays. Nevertheless,

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

Advanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals
