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.

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 cation induced actin ring formation

, 2011
In this paper we explored the effect of copper sulphate on the morphology of actin filaments. Actin filaments attain different shapes and structure when exposed to 2 mM concentration of copper sulphate.

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,

Molecular manipulation of polyamide nanostructures reconciles the permeance-selectivity threshold for precise ion separation

Nature Communications
Membrane nanofiltration (NF) has emerged as a prominent technology for efficient separations of ions, but state-of-the-art polyamide (PA) NF membranes are constrained by a pernicious tradeoff between water permeance and selectivity. This work conceives a

Precise Control of Charge-Structure Coupling in Polyamide Membranes for Mono- and Divalent Ion Separation. [PDF]

Adv Sci (Weinh)
A zwitterionic copolymer, Poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐2‐aminoethyl methacrylate hydrochloride) (P(MPC‐co‐AEMA)) copolymers, with tunable MPC/AEMA ratios, is grafted onto the polyamide (PA) selective layer via secondary interfacial polymerization. Balancing reactive anchoring segments (AEMA) and zwitterionic segments (MPC) regulated
