Abstract
Optical absorption spectra of para-aminothiophenol in n-hexane and methanol solutions have been obtained. The calculation has been carried out using the TDDFT B3LYP/6-311+G(d,p) method taking into account the polarizable continuum model of the electronic spectra of the p-aminothiophenol molecule in n-hexane and its hydrogen-bonded complex with two methanol molecules in a methanol solution. Based on these calculations, the main absorption bands are interpreted and it is shown that the second excited singlet state is formed by a π → σ* electronic transition, which makes a significant contribution to the first absorption band of p-aminothiophenol in these solutions.

Abstract
In this study, the UiO-66-NH2@PMAA metal-organic framework was prepared by using a hydrothermal reaction coupled with the gamma-ray irradiation method. The chemical structure of the product was studied using FTIR and XPS before and after irradiation, indicating the efficient development of the grafting reaction. The DSC results revealed a drop in the melting point of UiO-66-NH2@PMAA material, which might be attributed to PMAM grafting. Following that, different MOF materials were suction-filtered onto the surface of the membrane, and the alteration of their contact angle with time was recorded, indicating the enhancement of UiO-66-NH2@PMAA materials’ hydrophilicity. The modified MOF material has better dispersibility in aqueous solutions, providing reference significance for its application in related fields.

Abstract
Poly(S-bioallethrin) (PSBA) was grafted onto the polyvinylidene fluoride (PVDF) molecular chain through a gamma-ray irradiation method to prepare the PVDF-g-PSBA membrane. Fourier transform infrared spectroscopy (FTIR) of different membranes confirmed the effective progress of the grafting reaction. The microstructure of the membrane before and after irradiation was analyzed by scanning electron microscope (SEM), illustrating that gamma-ray irradiation did not cause damage to the membrane structure. The original PVDF membrane and the modified PVDF-g-PSBA membrane were immersed in an Escherichia coli culture medium, and the antibacterial effects of membranes were tested, confirming the positive effect of the PVDF-g-PSBA membrane on inhibiting bacterial growth. This research could have market application value in terms of altering membrane materials and enhancing membrane performance.

Abstract
Polyvinylidene fluoride (PVDF) membranes were created utilizing the non-solvent-induced phase separation (NIPS) approach in this study, then gamma-ray irradiation was applied to form the PVDF-g-PMAM membrane. FTIR and XPS were used to examine the chemical structure of the membrane before and after irradiation. The DSC curves of membranes showed that grafting poly methylacrylamide (PMAM) caused a drop in the melting point of the modified PVDF-g-PMAM membrane. The SEM characterization showed that gamma-ray irradiation did not damage the microstructure of the membrane cross-section, and the distribution of micropores on the membrane surface was more dense and uniform. The insertion of hydrophilic PMAM greatly accelerates the initial contact angle and contact angle decline rate of the PVDF-g-PMAM membrane, illustrating that the membrane’s hydrophilicity has been effectively improved. Finally, after testing of permeability and rejection of different membranes, the result demonstrated good anti-fouling performance.

Abstract
This work is devoted to numerical simulation of methane conversion to acetylene under plasma jet pyrolysis conditions and to comparison of simulation results with available experimental data. Calculations have been carried out in terms of the plug-flow reactor model for atmospheric pressure. The main processes of methane decomposition and acetylene formation have been analyzed for the case of using either hydrogen or methane as a plasma-forming gas. The results of calculations on the main products of methane decomposition (hydrogen and acetylene) are in good agreement with experimental data.

Abstract
For the first time, nanostructured thin films of the β-Ga2O3−GaN system have been obtained by plasma-enhanced chemical vapor deposition (PECVD) on c-plane sapphire substrates. High-purity gallium metal, as well as high-purity gaseous nitrogen and oxygen, were used as sources of macrocomponents. Low-temperature nonequilibrium plasma of an inductively coupled RF (40.68 MHz) discharge at reduced pressure (0.01 torr) was the initiator of chemical transformations between the reactants. A mixture of oxygen and nitrogen was used as a plasma-forming gas. The plasma-chemical process was studied using optical emission spectroscopy (OES). The resulting β-Ga2O3−GaN thin films with a GaN content of 2 to 7% were characterized by various analytical methods.

Abstract
Using fluorescence spectroscopy, the two-photon absorption cross sections of aqueous solutions of the styryl dye trans-4-[4-(dimethylamino)styryl]-1-methylpyridinium iodide (DASPI) and its inclusion complexes with cucurbit[n]urils (CB[n] n = 6–8) have been measured. A nonmonotonic dependence of the cross section on the excitation wavelength and on the cavitand cavity size has been revealed. Compared to the free dye, a sevenfold increase in the two-photon absorption cross section has been observed in DASPI inclusion complexes with CB[8] at an excitation wavelength of 980 nm.

Abstract
The possibility of using a series of methacrylate-containing N,N-diethyl-4-(phenyldiazenyl)anilines with various para-substituents (–H, –Br, –NO2) relative to the azo group as photoinitiators of radical polymerization is considered. The electrochemical and photoluminescent properties of these compounds have been studied. In the presence of azo dyes, two-photon photopolymerization of pentaerythritol triacrylate was carried out using focused 780-nm radiation from a femtosecond laser. Structures with minimal dimensions of linear elements of 94 ± 5 nm were obtained by means of the DLW nanolithography technique, and 3D microstructures of complex architecture were fabricated.
