Thin-Layer Chromatography

open access: yesMethods in molecular biology, 2021
Lipid extracts from plants represent a mixture of polar membrane lipids and nonpolar lipids. The main constituents of the polar lipid fraction are glycerolipids, that is, galactolipids, sulfolipid, and phospholipids. In addition, betaine lipids are found in pteridophytes, bryophytes, and algae. Nonpolar lipids include the storage lipid triacylglycerol,

Thin layer axion dynamo [PDF]

open access: greenEuropean Physical Journal C: Particles and Fields
We study interacting classical magnetic and pseudoscalar fields in frames of the axion electrodynamics. A large scale pseudoscalar field can be the coherent superposition of axions or axion like particles. We consider the evolution of these fields inside

Superconductivity in infinite-layer nickelate La1−xCaxNiO2 thin films [PDF]

open access: yesScience Advances, 2021
We report the observation of superconductivity in infinite-layer Ca-doped LaNiO2 (La1−xCaxNiO2) thin films and construct their phase diagram. Unlike the metal-insulator transition in Nd- and Pr-based nickelates, the undoped and underdoped La1−xCaxNiO2 ...

Thin-Layer Chromatography [PDF]

open access: yesJournal of Chromatographic Science, 2008
AbstractTLC is used extensively in nucleic acid chemistry to monitor the progress of chemical reactions, to assay fractions collected from a larger chromatographic separation (e.g., column chromatography), and to determine optimal conditions prior to column chromatography.

Longitudinal waves in an elastic rod caused by sudden damage to the foundation [PDF]

open access: yesTheoretical and Applied Mechanics, 2021
We study the problem of propagating longitudinal waves in an elastic rod connected to a locally damaged foundation through a thin elastic layer. The motion of the rigid foundation blocks is considered predetermined.

Influence of Geometry on Thin Layer and Diffusion Processes at Carbon Electrodes.

open access: yesLangmuir, 2021
The geometric structure of carbon electrodes affects their electrochemical behavior, and large-scale surface roughness leads to thin layer electrochemistry when analyte is trapped in pores.

Porosity prediction by geophysics technology at low-porosity and low-permeability reservoir of the Yinggehai Basin

open access: yes地质科技通报, 2022
The moderate deep and deeplayers of the Ledong area in the Yinggehai Basin is regarded as the main districts in recent exploration. The reservoirs in L10 zone are generally characterized by low-porosity and low-permeability, suggesting that the high ...

Critical transitions in thin layer turbulence [PDF]

open access: yesJournal of Fluid Mechanics, 2017
We investigate a model of thin layer turbulence that follows the evolution of the two-dimensional motions $\boldsymbol{u}_{2D}(x,y)$ along the horizontal directions $(x,y)$ coupled to a single Fourier mode along the vertical direction ( $z$ ) of the form
