Yuta Watanabe; Shoichi Katsuta * A nonintuitive observation of monovalent anion‐induced ion current rectification inversion at polyimidazolium brush (PimB)‐modified nanopipettes is presented. The rectification inversion degree is strongly dependent on the concentration and species of monovalent anions. The results suggest that bicarbonate is an essential anion which, together with the other major salivary inorganic monovalent anions, plays an active role in the lysis and ultimate elimination of cariogenic bacteria.

Generally, AEMs with monovalent selectivity are based on sieving and electrostatic repulsion mechanisms [ 12 ]. The monovalent selectivity is also influenced by membrane surface morphology and membrane surface hydrophilic–hydrophobic property [ 13 ]. Chaotropic Monovalent Anion‐Induced Rectification Inversion at Nanopipettes Modified by Polyimidazolium Brushes Dr. Xiulan He Beijing National Laboratory for Molecular Sciences, Key Laboratory of Analytical Chemistry for Living Biosystems, Institute of Chemistry, the Chinese Academy of Sciences (CAS), Beijing, 100190 China The monovalent anion permselectivity and fouling of the prepared membranes in the presence of humic acid (HA) through mass transport experiments is also assessed.

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. 2020-04-01 · This can be attributed to the following factors: (1) the suitability of the ion channel size for the monovalent anion (Cl −) (from the well-defined nano-phase separation structure of AEM) as a result of the polar disparity between alkyl spacers and (i) aromatic backbones and (ii) ion-conductive groups; (2) the enhanced hydrophobicity of membrane surface architecture, which helps to lower affinity of anions with higher hydration energy for the polymer matrix; (3) the discrepant 2013-03-15 · The monovalent anion selectivity of the modified membrane with negative surface charge (PSS top layer) increased with increasing numbers of layers, becoming constant above 15 layers. This was attributed to an increase in the total excess areal negative charge. We used dye-quenching halide assays and stopped-flow spectrometry to determine intrinsic permeability of three small monovalent halide anions (chloride, bromide, iodide) and one pseudohalide anion (thiocyanate) through narrow 0.8 nm diameter carbon nanotube porins (CNTPs).

structure Oct 17, 2016 Divalent ions have a stronger bond than monovalent ions.

From: Desalination , 2011 2013-03-15 2020-06-01 In general, the selectivity for monovalent anions can be realized through MASM with the mechanisms of: (1) Pore-size sieving effect (the different hydrated ionic radii) (2) Electrostatic repulsion (the difference in electrostatic repulsion between mono-/multi-valent anions) (3) Hydration energy difference (the different Gibbs hydration energy) etc. [5,9] Figure 2 illustrates the possible mechanisms of MASMs in ED … A new bio-inspired method was applied in this study to simultaneously improve the monovalent anion selectivity and antifouling properties of anion exchange membranes (AEMs). Three-layer • A monovalent molecular cation: the ammonium ion NH4 • A monovalent atomic anion: the chloride ion Cl — • A monovalent molecular anion: the nitrate ion NO 3 Monovalence or Monovalent may refer to: . Monovalent ion, an atom, ion, or chemical group with a valence of one, which thus can form one covalent bond; Monovalent vaccine, a vaccine directed at only one pathogen; Monovalent antibody, an antibody with affinity for one epitope, antigen, or strain of microorganism; Monovalent verb or Intransitive verb, a verb that takes no direct object and has The monovalent anions such as F(-), Cl(-), Br(-), I(-), and NO(3)(-) are essential for its exo-beta-1,4-glucanase activity but have no effect on the activity for xylan, while I(-) higher than 5mM would inhibit the exo-beta-1,4-glucanase activity. The monovalent anions Cl(-) and Br(-) activate its endo-beta-1,4-glucanase activity.
