WebApr 25, 2024 · Molecular adsorption on mineral surfaces has been a prominent research area in the field of surface chemistry. Among minerals, calcium carbonate (Ca 2 + CO 3 2 −) has attracted significant attention because it is the most abundant mineral in nature, constituting 4% by weight of the Earth’s crust [1,2,3,4,5,6].Calcium carbonate has three … WebNov 1, 2024 · The adsorption of l-gramicidin, a chiral pentadecapeptide, on D/L-methionine modified chiral surfaces was studied by Humblot and coworkers [112]. In their work, not only the chirality, but also the charge of the surface was considered. The cationic, zwitterionic and anionic chiral surfaces were used to adsorb l-gramicidin.

WebAlternatively, we can impart chirality onto surfaces by attaching irreversibly adsorbing chiral organic species on otherwise achiral surfaces. Understanding and ultimately controlling enantiospecific interactions of molecules on this kind of surfaces requires detailed insight into the adsorption geometries and energies of these complex interfaces. WebApr 13, 2024 · Selective adsorption of molecules on the surface of minerals has been suggested as one of many mechanisms for biohomochirality. 1. Bonner W.A. Kavasmaneck P.R. Martin F.S. ... The mechanism for the unexpected bias in the achiral solid-to-chiral solid phase transition is not fully understood. Two factors probably assist the effect. south trail hyundai reviews
