Chiral chromatography and surface chirality of carbon nanoparticles. [PDF]
Chirality, 2022 AbstractChiral carbon nanoparticles (CNPs) represent a rapidly evolving area of research for optical and biomedical technologies. Similar to small molecules, applications of CNPs as well as fundamental relationships between their optical activity and structural asymmetry would greatly benefit from their enantioselective separations by chromatography ...

Polarimetric Measurements of Surface Chirality Based on Linear and Nonlinear Light Scattering [PDF]
Frontiers in Chemistry, 2021 A molecule, molecular aggregate, or protein that cannot be superimposed on its mirror image presents chirality. Most living systems are organized by chiral building blocks, such as amino acids, peptides, and carbohydrates, and any change in their ...

High-throughput chiral copper foils by curved-surface confinement recrystallization [PDF]
Nature CommunicationsChiral metal surfaces play a pivotal role in enantioselective catalysis, sensing, and spintronics, yet their scalable fabrication remains challenging due to a reliance on chiral templates or molecular precursors, which limits both throughput and precise ...

Breaking of Odd Chirality in Magnetoelectrodeposition
Magnetochemistry, 2022 Electrodeposition under magnetic fields (magnetoelectrodeposition; MED) can induce surface chirality on copper films. The chiral signs of MED films should depend on the magnetic field polarity; namely, the reversal of the magnetic field causes the ...

Buckling of chiral elastic rings spanned by fluid films
Vietnam Journal of Mechanics, 2022 We use variational method to examine buckling of chiral elastic rings spanned by fluid films. We find that the critical surface tension of the fluid film at which buckling occurs depends on the degree of chirality, regardless whether the ring possesses ...

Breaking of Odd Chirality in Magnetoelectrodeposition of Copper Films on Micro-Electrodes
Magnetochemistry, 2021 The surface chirality was investigated in magnetoelectrodeposition (MED) of copper films on micro-disc electrodes with the diameters of 100 and 25 µm. The MED was conducted in the magnetic fields of 1–5 T, which were parallel or antiparallel to the ionic

Dynamic Diastereomerism on Chiral Surfaces
The Journal of Physical Chemistry C, 2022 Adsorption of chiral molecules on chiral surfaces implies diastereomerism, evident in the adoption of distinct adsorption geometries. We show here that this diastereomerism produces a signature in the motion of chiral molecules desorbing from a chiral surface. The rotations of S- and R-alanine molecules are analyzed upon desorption from R-Cu{531} using

Chiral Surface Lattice Resonances [PDF]
Advanced Materials, 2020 AbstractCollective excitation of periodic arrays of metallic nanoparticles by coupling localized surface plasmon resonances to grazing diffraction orders leads to surface lattice resonances with narrow line width. These resonances may find numerous applications in optical sensing and information processing.
