Extracellular divalent cations in excitation–contraction coupling: hypertonic solution effects

, 1982
It is the purpose of this article to point out that the membrane-bound Ca plays an important role in excitation–contraction (E–C) coupling of skeletal muscle fibers and that other divalent cations are unable to substitute for this role of membrane-bound

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

Advanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

Divalent Cations in the Envelope of a Psychrophilic Achromobacter [PDF]

Journal of General Microbiology, 1976
The function of Ca2+ in a psychrophilic Achromobacter, previously found to bind large amounts of these ions to its envelope, has been studied. Bacteria suspended in media of low ionic content showed decreases in wet weight, dry weight and growth capacity, and increases in light scattering and in the release of u.v.-absorbing substances into the medium.

Breaking Bottlenecks in Solid Electrolyte Discovery With Large Artificial Intelligence Models

Advanced Materials, EarlyView.
Large AI models are presented as a route to break key bottlenecks in solid electrolyte discovery by linking materials databases, machine‐learning interatomic potentials, large language models, and autonomous experiments. This perspective highlights how AI can accelerate the identification of solid electrolytes with fast ion transport, stable interfaces,

Modulation of Na+/alanine cotransport in liver sinusoidal membrane vesicles by internal divalent cations [PDF]

, 1990
Rat liver basolateral plasma membrane (bILPM) vesicles resuspended in 5 mM Mg2+-, Ca2+-, Mn2+- or Co2+-containing media exhibited a markedly lower rate of Na+-stimulated -alanine transport. Divalent cation inhibition of -alanine uptake was dose dependent,
