    Enantioselective HS-SPME-GC-MS for Authentication of Natural and Synthetic Strawberry Flavour in Syrups by Karolína Průchová, Adéla Grégrová, Hana Helísková, Vojtěch Kružík, Helena Čížková

    Published 2022-09-01
    “…Demand for a reliable distinction of the strawberry flavour naturalness stood in the beginning of this research. An efficient chiral column with CP-Chirasil-Dex CB stationary phase was involved in headspace solid-phase microextraction-gas chromatography-mass spectrometry analysis of strawberry flavour in 6 strawberry cultivars, 7 samples of strawberry flavourings and 14 samples of strawberry syrups to evaluate the authenticity of flavour naturalness and reveal adulteration. …”

    RS, S (+) - and R (−)-ibuprofen cocrystal polymorphs: Vibrational spectra, XRD measurement and DFT calculation studies by Yaqi Jing, Qiuhui Zhao, Jiale Zhang, Jiadan Xue, Jianjun Liu, Jianyuan Qin, Zhi Hong, Yong Du

    Published 2025-02-01
    “…In this paper, cocrystal polymorphs of RS-ibuprofen (RS-IBU), S (+)-ibuprofen (S(+)-IBU), R (−)-ibuprofen (R(−)-IBU) with nicotinamide (NIC) were synthesized by different methods. RS-IBU is a chiral drug with only one chiral center in the molecule, which has two enantiomers (S (+)-IBU and R (−)-IBU). …”

    Geometric phase analysis of magnetic skyrmion lattices in Lorentz transmission electron microscopy images by Thibaud Denneulin, András Kovács, Raluca Boltje, Nikolai S. Kiselev, Rafal E. Dunin-Borkowski

    Published 2024-05-01
    “…Here, we show that GPA can be applied quantitatively to Lorentz TEM images of two-dimensional skyrmion lattices obtained from a chiral magnet of FeGe. First, GPA is used to map deformation fields around a 5–7 dislocation and the results are compared with the linear theory of elasticity. …”
