aThe stationary phase is cation-exchange or anion-exchange resins that have fixed charges which attract the ions of opposite charge. Separation is effected by the strength of attraction of the analyte to the resin, which in turn is based on the size and charge on the analyte. 固定相是有...
A sterilizing method and apparatus in which neutral atoms and anions are coupled to produce a sterilizing substance which is, in turn, used to remove an object to be removed by sterilization. The sterilizing apparatus includes a cation generator and an anion generator, which are separate from ...
aan anionic chelating agent which increases the degree of swelling effected by said cation, with the proviso that said chelating agent is not citrate anion 增加程度膨胀的负离子螯合剂由说的正离子影响了,以说的螯合剂不是枸橼酸盐阴离子为条件[translate]...
Which of the following is not an ion? a.H+ Br− O2 Mg2+ Ion An ion is a particle that has a net electrical charge. An ion with a positive charge is called a proton and an ion with a negative charge is called an anion. When a stable atom gains or loses electr...
Kokufuta, Polyampholyte gels of a cross-linked polyanion or polycation network into which an oppositely charged polyanion is immobilized, Colloid Polym. Sci. 291 (2013) 669-681.Masaki, M.; Kokufuta, E. Polyampholyte gels of a cross-linked polyanion or polycation network into which an ...
To determine which cation has the maximum polarizing power, we can follow these steps: Step 1: Understand Polarizing PowerPolarizing power refers to the ability of a cation to distort the electron cloud of an anion. According to Fajan's rule, the polarizing power of a cation is directly prop...
S1), leading us to hypothesise that heparin is incorporated into these polymers. In a two-stage experiment, we found that SYTOX itself is not involved in the polymerization process (e.g. through cation-anion interactions). First, we allowed platelet aggregates to form in heparinised whole ...
Which cation in each set is expected to have the larger (more negative) hydration energy? I Be2+ or Ca2+ Which one of these ions has the largest ionic radius? a. Cl^- b. K^+ c. S^{2-} d. Na^+ e. O^{2-} For a pair, which ...
For example, in ion exchange chromatography (usually anion exchange chromatography), it is possible to separate the cellulase components by eluting with a pH gradient, or a salt gradient, or both a pH and a salt gradient. As used herein, the term "cellulase composition substantially free of ...
is well known24,25, in order to aid the interpretation of the results with EngU. The first detectable intermediate products of β-glucan cleavage by EngU were oligosaccharides with degree of polymerization (DP) ranging from 6 to 9 hexose moieties and larger, suggesting anendo-mechanism for β...
