PMID: 33855464
Acta Chim Slov. 2019 Feb;66(1):163-167.

In the present study a kinetic-spectrophotometric method for thiocyanate determination is described. The suggested method for the determination of thiocyanate is based on its "Landolt effect" on the reaction of bromate with hydrobromic acid, which leads to the formation...

Materials (Basel). 2021 Dec 02;14(23). doi: 10.3390/ma14237399.

Thin layers of silver nanowires are commonly studied for transparent electronics. However, reports of their terahertz (THz) properties are scarce. Here, we present the electrical and optical properties of thin silver nanowire layers with increasing densities at THz frequencies....

Dispersive Liquid-Liquid Semi-Microextraction of Сu(II) with 6,7-dihydroxy-2,4-diphenylbenzopyrylium Chloride for its Spectrophotometric Determination.

Acta chimica Slovenica

PMID: 33533449
Acta Chim Slov. 2020 Dec;67(4):1118-1123.

A novel dispersive liquid-liquid semi-microextraction (DLLsME) procedure for copper(II) preconcentration is proposed. The system containing copper(II) and 6,7-dihydroxy-2,4-diphenylbenzopyrylium chloride (DHDPhB), after addition a mixture of chloroform and methanol becomes cloudy and the formation of the organic phase was observed...

Stain-free subcellular-resolution astrocyte imaging using third-harmonic generation.

Optics letters

Pochechuev MS, Lanin AA, Kelmanson IV, Bilan DS, Kotova DA, Chebotarev AS, Tarabykin V, Fedotov AB, Belousov VV, Zheltikov AM.
PMID: 31199407
Opt Lett. 2019 Jun 15;44(12):3166-3169. doi: 10.1364/OL.44.003166.

We demonstrate stain-free, high-contrast, subcellular-resolution imaging of astroglial cells using epi-detected third-harmonic generation (THG). The astrocyte-imaging capability of THG is verified by colocalizing THG images with fluorescence images of astrocytes expressing a genetically encodable fluorescent reporter. We show that...

Multimodal nonlinear microscopy combining third-harmonic generation (THG) with two- and three-photon-excited fluorescence (2PEF and 3PEF) is shown to provide a powerful resource for high-fidelity imaging of nucleoli and nucleolar proteins. We demonstrate that, with a suitably tailored genetically encoded...
