H-Bond Acceptor Parameters for Anions.

Journal of the American Chemical Society, 2017
UV/vis absorption titrations have been used to investigate the formation of H-bonded complexes between anionic H-bond acceptors (HBAs) and neutral H-bond donors (HBDs) in organic solvents. Complexes formed by three different HBDs with 15 different anions

Salt Tolerance and Ion Accumulation in Several Halophytic Plant Species Depending on the Type of Anion

International Journal of Plant Biology, 2023
The question of the effect of the anion type on halophyte salt tolerance and ion accumulation is still far from the necessary generalization due to the lack of comparative studies.

Positron and positronium affinities in the work-formalism Hartree-Fock approximation

, 1999
Positron binding to anions is investigated within the work formalism proposed by Harbola and Sahni for the halide anions and the systems Li^- through O^- excluding Be^- and N^-.

Negative ions formed in N₂/CH₄/Ar discharge – a simulation of Titan's atmosphere chemistry [PDF]

, 2009
The formation of negative ions produced in a negative point-to-plane corona discharge fed by a Ar/N2//CH4/ gas mixture has been studied using mass spectrometry.

A readily accessible multifunctional probe: simultaneous recognition of the cation ZN²⁺ and the anion F⁻ via distinguishable wavelengths [PDF]

, 2017
The probe 1 was readily prepared via condensation of 8-formyl-7-hydroxy-coumarin and carbonic dihydrazide in a one-step procedure. Probe 1 exhibited high sensitivity and selectivity towards Zn²⁺ and F⁻ through a “turn-on” fluorescence response and/or ...

A Comparative Study on Removal of Hazardous Anions from Water by Adsorption: A Review

, 2018
This paper presents a comparative review of arsenite (As(III)), arsenate (As(V)), and fluoride (F−) for a better understanding of the conditions and factors during their adsorption with focus on (i) the isotherm adsorption models, (ii) effects of pH ...

Stabilizing electrodeposition in elastic solid electrolytes containing immobilized anions

Science Advances, 2016
Elastic deformation in solid electrolytes with immobilized anions suppresses dendritic electrodeposition of metals. Ion transport–driven instabilities in electrodeposition of metals that lead to morphological instabilities and dendrites are receiving ...

Anion Inhibition Profile of the β-Carbonic Anhydrase from the Opportunist Pathogenic Fungus Malassezia restricta Involved in Dandruff and Seborrheic Dermatitis

Metabolites, 2019
Carbonic anhydrases (CAs, EC 4.2.1.1) are ubiquitous metalloenzymes, which catalyze the crucial physiological CO2 hydration/dehydration reaction (CO2 + H2O ⇌ HCO3− + H+) balancing the equilibrium between CO2, H2CO3, HCO3− and CO32−.
