The calculation of the adsorption energy distribution (AED) was recently introduced as an important tool for the chromatographic community for characterization of modern phases. The AED-calculations, provides model-independent information about the numbers of different adsorption sites and their respective energy-levels

Host-guest interactions of permethylated β-cyclodextrin (PM-β-CD) with methyl mandelate enantiomers ((R/S)-MMA) were simulated using semiempirical PM3 and ONIOM (B3LYP/6-31G(d):PM3) method. The chiral recognition mechanism of (R/S)-MMA enantiomers on PM-β-CD was investigated. The binding energies for all orientations considered in this

Enantiomer separation of mandelates and their analogs, which are important intermediates in asymmetric synthetic and pharmaceutical chemistry, was investigated by capillary gas chromatography using different cyclodextrin derivative chiral stationary phases (CD CSPs). The used cyclodextrin derivatives included permethylated beta-CD (PMBCD)

Flash photolysis of methyl phenyldiazoacetate in aqueous solution produced phenylcarbomethoxycarbene, whose hydration generated a short-lived transient species that was identified as the enol isomer of methyl mandelate. This assignment is supported by the shape of the rate profile for decay

Despite directed evolution being a practical and efficient method of improving the properties of enzymes, a trade-off between the targeted property and other essential properties often exists which hinders the efficiency of directed evolution. In our previous work, mutant CVH
