The Spin Physics Detector collaboration proposes to install a universal detector in the second interaction point of the NICA collider under construction (JINR, Dubna) to study the spin structure of the proton and deuteron and other spin-related phenomena using a unique possibility to operate with polarized proton and deuteron beams at a collision energy up to 27 GeV and a luminosity up to 10^32 cm^-2 s^-1. As the main goal, the experiment aims to provide access to the gluon TMD PDFs in the proton and deuteron, as well as the gluon transversity distribution and tensor PDFs in the deuteron, via the measurement of specific single and double spin asymmetries using different complementary probes such as charmonia, open charm, and prompt photon production processes. Other polarized and unpolarized physics is possible, especially at the first stage of NICA operation with reduced luminosity and collision energy of the proton and ion beams. This document is dedicated exclusively to technical issues of the SPD setup construction.

New hybrid materials based on Ag nanoparticles stabilized by a polyaminopropylalkoxysiloxane hyperbranched polymer matrix were prepared. The Ag nanoparticles were synthesized in 2-propanol by metal vapor synthesis (MVS) and incorporated into the polymer matrix using metal-containing organosol. MVS is based on the interaction of extremely reactive atomic metals formed by evaporation in high vacuum (10−4–10−5 Torr) with organic substances during their co-condensation on the cooled walls of a reaction vessel. Polyaminopropylsiloxanes with hyperbranched molecular architectures were obtained in the process of heterofunctional polycondensation of the corresponding AB2-type monosodiumoxoorganodialkoxysilanes derived from the commercially available aminopropyltrialkoxysilanes. The nanocomposites were characterized using transmission (TEM) and scanning (SEM) electron microscopy, X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (PXRD) and Fourier-transform infrared spectroscopy (FTIR). TEM images show that Ag nanoparticles stabilized in the polymer matrix have an average size of 5.3 nm. In the Ag-containing composite, the metal nanoparticles have a “core-shell” structure, in which the “core” and “shell” represent the M0 and Mδ+ states, respectively. Nanocomposites based on silver nanoparticles stabilized with amine-containing polyorganosiloxane polymers showed antimicrobial activity against Bacillus subtilis and Escherichia coli.

A promising method was proposed for the sulfonation of polyphenylquinoxaline films with sulfuric acid. The sulfonation in the films was confirmed by X-ray photoelectron and IR spectroscopies. The thermal characteristics and dielectric properties of the sulfonated films were studied.

Polydimethyl(methylvinyl)siloxane with long-chain hydrocarbon fragments was synthesized at a sequence of chemical reactions. The resulting graft copolymer was used as a compatibilizer of ethylene propylene diene/siloxane rubbers blends of different compositions. It has been established that the introduction of reactive compatibilizer in a concentration not higher than 6 wt.% in the blend of rubbers allows to increase their compatibility due to co-vulcanization of graft copolymer with each of the components under the hydrosilylation conditions and, possibly, due to the formation of chemical bonds between rubber phases, which leads to an increase in the strength properties of the compositions.

In the present study, we report the synthesis of a series of copper(II) complexes with a wide range of ligands and their testing in the copper catalyzed Chan-Evans-Lam (CEL) coupling of aniline and phenylboronic acid. The efficiency of the coupling was directly connected with the ease of the reduction of Cu(II) to Cu(I) of the complexes. The most efficient catalyst was derived from 4-t-butyl-2,5-bis[(quinolinylimino)methyl]phenolate and two Cu(II) ions. Depending on the counter-anion nature and the concentration of the reaction mixture, the reaction can be directed to predominant C-N-bond formation. Forty-three derivatives of diphenylamine were prepared under the optimized conditions. The proposed mechanism of the catalysis was based on the reduction potential of a series of complexes, molecular weight measurements of the catalytic complex in MeOH and the kinetic studies of aniline and phenylboronic acid coupling. In addition, an H-1 NMR experiment in a sealed NMR tube, without external oxygen supply available, proved that no complete Cu(II) to Cu(I) conversion was observed under the condition, ruling out the usually accepted mechanism of the C-N coupling, which included the oxygenation of the intermediately formed Cu(I) complexes after the key step of C-N conversion had already been completed. Instead, a mechanism was proposed, involving an oxygen molecule coordinated to two copper ions in the key C-N bond formation without any detectable conversion of the Cu(II) complexes to Cu(I).

Polyblock butylenoxide-siloxaneurethane elastomers with a specific chemical structure defined by a changed content of butylene oxide and dimethylsiloxane prepolymers with NCO terminal groups are prepared by a directed one-step synthetic procedure. The synthesis is carried out at room temperature in methyl ethyl ketone without catalysts and chain extenders using aromatic diamines as crosslinking agents. The proposed method allows one to obtain copolymers with a different structure. Such copolymers have high deformation and strength characteristics and are promising in medicine.

Nanocrystalline graphite samples obtained by the sonication of TEG in water and glycerol have been investigated by XPS and AES. The ultrasonic treatment of graphite leads to the loosening of its edges, increases the number of defects in layers, and promotes the penetration of a modifying fluid into the interlayer space in the peripheral areas. The dissociation on internal defects with the formation of C–OH groups is possible in the case of water. In friction against a thoroughly polished steel surface, modified graphite particles have demonstrated a lower coefficient of friction but a shorter lifetime than original graphite.

Using the XPS method the possibility of the formation of fluoro-containing polymer brushes based on organofluorosilicon compounds and epoxy matrix has been investigated. The advantages and disadvantages of this approach for the surface modification of solid substrates by fluoro-containing compounds have been discussed.

The morphology and thermal and mechanical properties of siloxane urethane block copolymers based on oligosiloxane- and oligoalkylene diols are investigated. The dependence of morphology on the conditions of synthesis is studied via atomic force microscopy and scanning electron microscopy.

Structures of amorphous polyether urethanes modified with oligomeric organosilicon blocks are studied via AFM, SEM, and TEM. The main structural unit of the investigated polymers is found to be a globule. The effect the silicon modifier has on the polyether urethane structure is determined.

The effects of plasmochemical processing and of Ce, K, and Hf additives on the rate of dehydrogenation for isopropyl alcohol on a 5 wt % Co/SiO2 catalyst is studied under static and flow conditions. Glow discharge plasma in O-2 and Ar and high-frequency electrodeless plasma in H-2 (HF-H-2) are used. Except for one sample containing Hf, an increase in catalytic activity is observed due to the formation of new active centers. The change in the composition of the initial catalyst's surface after treatment with Ce and with oxygen, argon, and HF-H-2 plasmas is determined by means of X-ray photoelectron spectroscopy. The change in the size and shape of Co particles after treating the catalyst with HF-H-2 plasma and Ce is determined via X-ray phase analysis. It is suggested that the new catalytic centers formed after treatment in O-2 and Ar plasma contain carbon atoms with C1s bond energies of 282.1 eV; after treatment with HF-H-2 plasma, active centers contain hydrogen and carbon atoms with C1s bond energies of 282.5 eV; with cerium, the C1s bond energy is 297.7 eV.
