Gas chromatographic enantiomer separation on single and mixed cyclodextrin derivative chiral stationary phases

, 2000
Capillary gas chromatographic enantiomer separation of some polar compounds, including alpha-phenylethylamine, styrene oxide, pyrethroid insecticides and other carboxylates, was investigated on modified cyclodextrin (CD) chiral stationary phases.

Holographic description of the QCD phase diagram and out of equilibrium dynamics

, 2014
Holography provides a powerful tool to model QCD and other strongly coupled gauge dynamics. As examples of its power to compute in novel environments I review some recent results: these include models of the phase structure of QCD at finite temperature ...

Thiooxamide chiral stationary phase for liquid chromatography

, 2005
A new chiral stationary phase was prepared by reaction of aminopropylsilica with N-(α-phenylethyl)chloroacetamide in the presence of sulfur and used for the high performance liquid-chromatographic separation of 1,1′-binaphthyl-2,2′-diol and Tröger ...

Chiral separation by capillary electrochromatography with physically adsorbed stationary phase and dynamically modified stationary phase

, 2001
A novel mode of chiral separation in electrochromatogaphy (CEC) with dynamically modified stationary phase (DMS-CEC) was presented. The capillary column was packed with strong anionic exchange stationary phase, the sulfated beta -cyclodextrin (S-CD ...

Simultaneously molecular imprinting chiral stationary phase

, 2000
Molecular imprinting chiral stationary phases against amino acid derivatives were preparted by utilizing two template molecules simultaneously and evaluated in high performance liquid chromatographic mode. It was found that when both of the two molecular

Dynamic Generation of Spatially Variable Vector Beams Using Cascaded Moiré Metasurfaces

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A three‐layer cascaded moiré metasurface dynamically generates vector beams with tunable polarization order and controllable lateral focal positions. Relative rotation of the first two layers adjusts the conjugate OAM components that form the vector beam, whereas the third layer steers its focus across the transverse plane, preserving the dominant OAM ...

Misaligning Cascaded Liquid Crystal Elements for Continuously Tunable Axial Spin‐Dependent Splitting

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Continuously tunable axial spin splitting is achieved by controlling the lateral misalignment of cascaded Pancharatnam‐Berry phase liquid crystal elements. The displacement generates a spin‐dependent quadratic phase, enabling linear, sign‐reversible focal adjustment and dynamic focus interchange for orthogonal circular polarizations.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, Volume 600, Issue 17, Page 2564-2578, September 2026.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...
