Modelling of the monitoring and control system of extraction units with nuclear-safe tanks via use of capillary impulse lines with differential low-pressure gages

This paper focuses on the computer-aided simulation of extraction process in the cascade of reverse-flow centrifugal extractors with nuclear-safe tanks. The major objective of this work is to design an advanced control system for enhancement of extracting technology efficiency. The basis of the monitoring and control system is that the systems should be based on non-destructive measuring techniques. Two models of monitoring systems are being considered: the measuring system in nuclear-safe tanks where capillary impulse lines are used for measurement of differential pressure at various points in the process media, and model of spectrometric system. The density measurement in both presented systems is indirect. The experimental studying of monitoring spectrometric system have shown that the accuracy of experimental data less than 1 % in steady-state condition and more than 3 % in a dynamic one. The accuracy degradation is due to air bubbles presents in the solvent stream

Plier Ligands for Trapping Neurotransmitters into Complexes for Sensitive Analysis by SERS Spectroscopy

Catecholamines–dopamine, noradrenaline and adrenaline are important biomarkers of neurotransmitter metabolism, indicating neuroendocrine tumors and neurodegenerative diseases. Surface-enhanced Raman spectroscopy (SERS) is a promising analytical technique with unprecedented multiplexing capabilities. However, not all important analytes exhibit strong SERS signals on stable and robust nanostructured substrates. In this work, we propose a novel indicator system based on the formation of mixed ligand complexes with bispidine-based bis-azole ligands which can serve as pliers to trap Cu(II) ions and stabilize its complexes with catecholamines. Four synthesized ligands with different functional groups: carboxyl, amino, benzyl, and methoxybenzyl, were applied for forming stable complexes to shift maximum absorbance of catecholamines from the ultraviolet region to 570–600 nm. A new absorbance band in the visible range resonates with the local surface plasmon resonance (LSPR) band of metal nanoparticles and most used laser wavelengths. This match allowed use of Molecular Immobilization and Resonant Raman Amplification by Complex-Loaded Enhancers (MIRRACLE) methodology to measure intense Raman signals on a nanostructured silver-based SERS-active substrate. The synthesized plier-like ligands fixed and stabilized catecholamine complexes with Cu(II) on the SERS sensor surface, which facilitated the determination of dopamine in a 3.2 × 10−12–1 × 10−8 M concentration range
