The paper presents the experimental results of nanostructures formation under the influence of femtosecond laser radiation on carbon samples at liquid nitrogen temperatures. Two femtosecond laser systems were used to study the processes of laser action on highly oriented pyrolytic graphite and glassy carbon samples in liquid nitrogen: titanium-sapphire laser system with wavelength 800 nm, pulse duration 50 fs, energy 1 mJ, and repetition frequency of 1 kHz; ytterbium laser system with wavelength 1030 nm, pulse duration 280 fs, energy 150 µJ, and repetition frequency of 10 kHz. Cryostats, including those with the possibility of observing the laser action process, were collected for the experiments. As a result of laser action on the surface of the processed carbon samples, sheets of exfoliated graphene of various sizes and shapes (sheets, tapes, crumpled graphene), as well as nanostructures in the form of nanopeaks, were obtained. The mechanisms of graphene exfoliation under femtosecond laser action in liquid nitrogen, consisting in intercalation and further heating of nitrogen molecules in the interplanar space of graphite, were proposed. The possibilities of further research and development of technologies for graphene formation using laser radiation are presented.

The proposed review represents the systematic analysis of modern methods and approaches for the characterization and structural evaluation of fluorinated polymers that have found a wide application as materials for chemical processing, chemically resistant components and coatings, pharmaceutical and electrical packaging, biomedical equipment, etc. The chemical composition of the polymers (fluorine content, its distribution inside the fluorinated materials, chemical bonds, presence of oxygen-containing groups) substantially influences on the operation properties (chemical resistance, adhesive, cohesive, optical, dielectrical, thermal, barrier, gas permeation) of the final polymeric products. Hence, it was of particularly importanсe to bond the emergence of specific features with the presence of fluorine in the chemical structure of polymer by means of related analytical techniques. Namely, we focused on spectral (IR, UV-VIS, NMR, XPS, EPR), chemical (elemental analysis), Secondary-ion mass spectroscopic (SIMS) and microscopic (AFM, SEM-EDX) methods emphasizing their general consideration and limitations as well as application for the in-depth characterization.

In the early 1980s, French physicist G. Mourou and his Canadian collaborator D. Strickland solved the problem of power drop by dispersing in time and space the processes of amplification and compression: a method of obtaining super-powerful chirped laser pulses (CPA – chirped pulse amplification). The paper presents brief biographical references to Mourou and Strickland. The 2018 Nobel Prize in Physics was awarded “for groundbreaking inventions in the field of laser physics”: Artur Isidorovich Ashkin (Ashkinazi, born 02.09.1922, USA), half of the prize “for the optical tweezers and their application to biological systems”; Gerard Albert Mourou and Donna Theo Strickland (became the third woman to be awarded the Nobel Prize in Physics) (quarterly premium) “for their method of generating high-intensity, ultra-short optical pulses”. Since that time all lasers have been built on a new principle: after the amplifiers place a compressor from diffraction bars. Instead of simply amplifying the pulse, it is first spread out on spectral components spread over time, then they are amplified separately, then again assembled into a single pulse. At each point in time, only a fraction of the pulse is amplified, not the entire pulse, allowing for a much higher peak intensity of laser light flow.

The paper studies the oxidation laws of multiwalled carbon nanotubes (MWCNTs) of various types, which differ in geometric parameters (diameter, length, specific surface), using nitric acid. In different experiments, the duration of oxidation, the concentration of nitric acid, and the consumption of HNO3 per 1 g of MWCNTs were varied. The qualitative composition of the formed oxygen-containing functional groups and the changes occurring with the graphene layers of nanotubes were established by the methods of IR and Raman spectroscopy, and transmission electron microscopy. The total oxygen content in the samples was determined by energy dispersive analysis. The degree of MWCNTs functionalization with acidic functional groups was determined by Boehm titration. An X-ray structural analysis of the obtained samples was carried out and their specific surface area was estimated. It was determined that the most serious changes in the functionalization degree occurred during the first 1–3 hours of oxidation. During this time interval, the achieved values of the functionalization degree were determined mainly by the shape of the MWCNTs graphene layers. At 7–10 hours of treatment, regardless of the initial parameters, MWCNTs have the functionalization degree in the range of 0.5–0.7 mmoLg–1. At the initial stage of oxidation, the amorphous phase is removed. Using dilute solutions of nitric acid does not allow obtaining oxidized nanotubes with the high functionalization degree. It is expedient to reduce the consumption of 65 % HNO3 to 40 mL per 1 g of MWCNTs.

Catalysts of carbon monoxide oxidation were synthesized by deposition of platinum on titanium nitride (TiN). Two substrates with an average particle size of 18 and 36 nm were obtained by hydrogen reduction of titanium tetrachloride in a stream of microwave plasma of nitrogen. The surface of the catalysts was studied by X-ray photoelectron spectroscopy (XPS). The data obtained by us in the present work indicate the presence of oxynitride as a transition layer between nitride and oxide. It was found that the CO oxidation rate on the 9–15 wt. % Pt loaded TiN catalysts is 120 times higher than that on the platinum black with a specific surface of 30 m2g–1. Increase in the reaction rate of CO oxidation on Pt/TiN catalysts as compared to platinum black can be associated with both an increase in the concentration of CO molecules adsorbed and a decrease in the activation energy of the reaction. Catalysts are promising for use in catalytic air purification systems.

Currently, soft hydrogels with antimicrobial properties are widely used in biomedical applications as dressings and wound healing agents. In the present work, Cu–Fe nanoparticles with different component ratios were obtained by the joint electric explosion of iron and copper wires in an argon atmosphere. Bimetallic nanoparticles had a clear interface between the iron and copper phases at the particle level. Cu–Fe nanoparticles had high antibacterial activity against a wide bacterial spectrum. In connection with dusting and entrainment of nanoparticles, for the convenience of biomedical application, compositions were created based on non-toxic biocompatible polymers – polyvinyl alcohol, polyacrylic acid, and polyacrylamide. The suspension of nanoparticles was pretreated with ultrasound for 5 min at a frequency of 22.4 kHz. Polyvinyl alcohol was used as a nanoparticle stabilizer. The stability of the suspension was investigated by the sedimentation method. The resulting compositions effectively inhibited the growth of Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538, methicillin-resistant Staphylococcus aureus ATCC 43300 (MRSA), and Pseudomonas aeruginisa ATCC 9027.
