Mechanisms of Ions Adsorption by Nanodiamonds in Aqueous Suspensions
This work is devoted to the study of adsorption properties and adsorption mechanisms of the original (I6), modified (I6COOH) nanodiamonds and charcoal dispersed in water, with respect to dissolved ions (Cu2 +, Pb2 +, NO3 β, CH3COO β) using optical spectroscopy methods: Raman and IR spectroscopies, absorption, dynamic light scattering. Mechanisms of anions and cations adsorption were studied.

In this study, we considered the problem of determining the concentrations of ions dissolved in water by the spectra of Raman scattering of light. At the moment, there are no adequate mathematical models describing the studied object, so in fact the only way to solve this problem is the use of machine learning methods based on experimental data. As any data resulting from experimental measurements contain noise, there is a need to develop specific approaches to improving the resilience of the solution to noise in the data. Regarding the studied problem, experimental data may contain distortions of three types: variations in the concentrations of ions, error in the determination of the intensity in the channels of the spectra, and frequency shift of the channels of the spectrum. This study is devoted to the development of approaches to improve the resilience of the neural network solution to the distortions caused by the shift of the spectral channels.Π Π°Π±ΠΎΡΠ° Π²ΡΠΏΠΎΠ»Π½Π΅Π½Π° Π·Π° ΡΡΠ΅Ρ Π³ΡΠ°Π½ΡΠ° Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠ³ΠΎ Π½Π°ΡΡΠ½ΠΎΠ³ΠΎ ΡΠΎΠ½Π΄Π° (ΠΏΡΠΎΠ΅ΠΊΡ β 14-11-00579)

develop a new method for monitoring the excreted nanocomposite carriers of drugs and their
components from the fluorescence spectra. The situation of removal of nanocomposites
consisting of fluorescent carbon dots covered with copolymers and ligands of folic acid and
their components with urine was modeled and the problem of classification of all nanoparticles
was solved. Various architectures of neural networks were used for solving this problem, as
well as compression of input features: cross-correlation, cross-entropy, standard deviation, use
of the analysis of the neural network weights. The best results of the classification of
nanocomposites and their components in urine are provided by a perceptron with 8 neurons in
a single hidden layer, trained on a set of significant input features identified by crosscorrelation.
The percentage of correct recognition, averaged over all possible five classes of
nanoparticles, is 75.8%.Π Π°Π±ΠΎΡΠ° Π²ΡΠΏΠΎΠ»Π½Π΅Π½Π° Π·Π° ΡΡΠ΅Ρ Π³ΡΠ°Π½ΡΠ° Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠ³ΠΎ Π½Π°ΡΡΠ½ΠΎΠ³ΠΎ ΡΠΎΠ½Π΄Π° (ΠΏΡΠΎΠ΅ΠΊΡ β 17-12-01481)
