Crown ether exhibits a high separation coefficient for lithium isotope separation owing to its precise size selectivity to cations. A crown ether-based solid–liquid extraction method for the lithium isotope separation with a high extraction efficiency is regarded as a valid alternative to the classic liquid–liquid method.

Abstract. Studying complex molecules of organic and biological interest usually demands the employment of molecular mechanical methods.

Unlike first principle quantum mechanical electronic structure methods, molecular mechanical methods (e.g. 1) require that chemical bonds in the system be specified and these are present throughout the : Peter Kollman.

Non-covalent interactions between metal ions and an aromatic ring, which are considered strong cation-aromatic interactions, are increasingly being recognised as an important binding force relevant to structural biology [Meyar et al., ; Elguero et al., ].

However, in many cases, the cation is the side chain protonated nitrogen of a. NMR and stopped-flow studies of metal ion binding to α-lactalbumins James M.

Aramini, Toshifumi Hiraoki, Michael R. Grace, Thomas W. Swaddle, Emilia Chiancone, and Hans J. ogel Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology,VolumeNumber 1. Introduction Metal ions play a major role in biological processes, whether it be structural (e.g.

stabilizing various protein or nucleic acid configurations) or functional (e.g. being second messengers, or being the active site of metalloenzymes).Of particular interest to the concepts described within this review is the biology of the late first row transition metals Fe, Cu and Zn.

The interaction of metal ions with mitochondrial proteins that might be responsible for these toxic effects was investigated in vitro using IMAC to trap metal-binding proteins.

Initial studies used Ca 2+, Co 2+, Cu 2+, Fe 3+, Mg 2+, Mn 2+, or Zn 2+ to charge the IMAC resin (Fig. 1A). Today studies of non-covalent interactions, mainly by artificial model structures and receptors, have led to a far better understanding of many biological processes.

Moreover, they are often the inspiration for supramolecular research, including self-assembly, mechanically-interlocked molecular architectures and molecular recognition in host.

Mobile Li + ions between supertetrahedra: The phosphidosilicates Li 2 SiP 2 and LiSi 2 P 3 form interpenetrating covalent networks of T2 or T4 and T5 supertetrahedra with diamond‐ or sphalerite‐type topologies. 7 Li solid‐state MAS NMR analysis indicates the high mobility of the Li + ions with small activation energies of – eV.

This concise and modern book provides a complete overview of both solvent extraction separation techniques and the novel and unified competitive complexation/solvation theory.

This novel and unified technique presented in the book provides a key for a preliminary quantitative prediction of suitable extraction systems without experimentation.

The sensing mechanism of fluorescent ion-selective nanosensors incorporating solvatochromic dyes (SDs), with K+ as model ion, is shown to change as a function of dye lipophilicity. Water-soluble SDs obey bulk partitioning principles where the sensor response directly depends on the lipophilicity of the SD and exhibits an influence on the phase volume ratio of nanosensors to aqueous solution.
