Separation of specific single-enantiomer single-wall carbon nanotubes in the large-diameter regime [PDF]
ACS Nano, 2019 The enantiomer-level isolation of single-walled carbon nanotubes (SWCNTs) in high concentration and with high purity for nanotubes greater than 1.1 nm in diameter is demonstrated using a two-stage aqueous two-phase extraction (ATPE) technique.

Strong Coupling in Chiral Cavities: Nonperturbative Framework for Enantiomer Discrimination [PDF]
Physical Review X, 2022 The development of efficient techniques to distinguish mirror images of chiral molecules (enantiomers) is very important in both chemistry and physics.

Quantitative Study of Enantiomer-Specific State Transfer. [PDF]
Physical Review Letters, 2021 We here report on a quantitative study of enantiomer-specific state transfer, performed in a pulsed, supersonic molecular beam. The chiral molecule 1-indanol is cooled to low rotational temperatures (1-2 K) and a selected rotational level in the ...

Two-Path Interference for Enantiomer-Selective State Transfer of Chiral Molecules [PDF]
Physical Review Applied, 2020 With a microwave-regime cyclic three-state configuration, an enantiomer-selective state transfer~(ESST) is carried out through the two-path interference between a direct one-photon coupling and an effective two-photon coupling. The $\pi$-phase difference

BCL::EMAS — Enantioselective Molecular Asymmetry Descriptor for 3D-QSAR
Molecules, 2012 Stereochemistry is an important determinant of a molecule’s biological activity. Stereoisomers can have different degrees of efficacy or even opposing effects when interacting with a target protein.

Enantiomer fractions instead of enantiomer ratios [PDF]
, 2000 The use of enantiomer ratios (ERs) to indicate the relative amounts of a pair of enantiomers in a sample has some disadvantages. Enantiomer fractions (EFs) are proposed as all alternative expression to eliminate the difficulties.
