Super-plasticity of inorganic semiconductors (Prof. Yu. Tveryanovich)

Nowadays, flexible electronics is developing rapidly. This is due not only to the convenience of using flexible devices, but also to the possibility of placing them (including various sensors) directly on controlled moving objects, for example on human body. Because of their high fragility, classical semiconductors cannot be used in flexible electronics. Indeed, crystalline semiconductors can be formed only by covalent bonds, which are short-range and directional, and thus determine their fragility. There is fairly large number of organic semiconductors, various kinds of "ink" for printing electronic circuits, etc. However, using them is associated with various difficulties, including rapid degradation of their properties, problems in controlling their electrical properties, and a number of other difficulties. Overcoming them would require much effort and time. This is why the possibility of creating crystalline inorganic semiconductors with high ductility is extremely attractive. This problem also has another aspect.

We are talking about fragility of glassy semiconductors or chalcogenide glasses that are also covalent substances. They are used in IR optics, particularly in the form of optical fibers and waveguides, and are also used in devices for optical recording, storage and reading of information. Giving them plasticity would significantly expand the scope of their application. Therefore, the discovery the plasticity in crystalline semiconductor, comparable to that in metals, launches a new direction in the development of semiconductor materials for flexible electronics.

Laser-induced modification (Dr. Povolotskiy A.V.)

To date, organic materials treated with laser radiation have been increasingly used in the design and manufacture of optical elements. PMMA is one of the widely used polymeric materials in optics and optoelectronics. The main advantages of PMMA are a wide transparency window, the possibility of forming both bulk and film materials. Laser modification of PMMA allows creating color centers with radiation in a wide spectral range. Laser-assisted modification of PMMA thin films lead to the white-light color centers formation with quantum efficiency up to 38 %. Wide spectral range of PMMA luminescence excitation, allows creating a white light source based on LEDs with any wavelength in UV-vis region.

Molecular-plasmon nanostructures for biomedical application (Dr. Povolotskiy A.V.)

The development of modern nanotechnology opens new opportunities in the design of hybrid structures. This work is devoted to the general view on hybrids, which are based on metal nanoparticles and molecules. Functional properties of nanostructures that have a biomedical application are presented, including singlet oxygen generation for photodynamic therapy, photo-induced heating for photothermal therapy, photo-induced reactions for chemotherapy, luminescent thermometry and surface enhanced Raman scattering for drug delivery control etc. The association of nanostructures into hybrids allows to combine their functional properties and create universal preparations for controlled complex therapy.

(SJR=4,224) Q1(2018)

Nonlinear optical (NLO) crystals are widely used in advanced photonic technologies for second harmonic and difference frequency generation (SHG and DFG, respectively), producing coherent light at frequencies where existing lasers are unavailable. Isotropic glasses do not exhibit SHG or DFG, except temporarily induced anisotropy under external stimuli. However, recent reports on glasses with chiral structural motifs show promising permanent NLO properties. We propose an alternative solution: hybrid molecular/network glasses with noncentrosymmetric HgI₂ monomers. Mercury-(II) iodide consists of linear HgI₂ triatomic molecules in the vapor phase and in the yellow orthorhombic polymorph stable above 400 K. At lower temperatures, the tetragonal red form is composed of corner-sharing HgI_4/2 tetrahedra forming a layered extended framework. There is a gap in the molecular evolution; direct structural measurements of the liquid HgI₂ phase are missing. Using high-energy X-ray scattering, pulsed neutron diffraction, and Raman spectroscopy supported by structural and vibrational modeling, we show that the mercury(II) iodide melt and HgI₂-containing sulfide glasses are built up by bent HgI₂ monomers (the bond angle ∠I−Hg−I = 156 ± 2° in the melt). The noncentrosymmetric entities imply intrinsic optical nonlinearity of the second order, confirmed by a strong SHG response.

Nikolaev, D.M., Shtyrov, A.A., Mereshchenko, A.S., Panov, M.S., Tveryanovich, Y.S. and Ryazantsev, M.N., 2020. An assessment of water placement algorithms in quantum mechanics/molecular mechanics modeling: the case of rhodopsins’ first spectral absorption band maxima. Physical Chemistry Chemical Physics, 22(32), pp.18114-18123. DOI: 10.1039/D0CP02638G (Ph.D. Ryasantsev M.N.)

Quantum mechanics/molecular mechanics (QM/MM) models are a widely used tool to obtain detailed insight into the properties and functioning of proteins. The outcome of QM/MM studies heavily depends on the quality of the applied QM/MM model. Prediction and right placement of internal water molecules in protein cavities is one of the critical parts of any QM/MM model construction. Herein, we performed a systematic study of four protein hydration algorithms. We tested these algorithms for their ability to predict X-ray-resolved water molecules for a set of membrane photosensitive rhodopsin proteins, as well as the influence of the applied water placement algorithms on the QM/MM calculated absorption maxima (λmax) of these proteins. We used 49 rhodopsins and their intermediates with available X-ray structures as the test set. We found that a proper choice of hydration algorithms and setups is needed to predict functionally important water molecules in the chromophore-binding cavity of rhodopsins, such as the water cluster in the N-H region of bacteriorhodopsin or two water molecules in the binding pocket of bovine visual rhodopsin. The QM/MM calculated λmax of rhodopsins is also quite sensitive to the applied protein hydration protocols. The best methodology allows obtaining an 18.0 nm average value for the absolute deviation of the calculated λmax from the experimental λmax. Although the major effect of water molecules on λmax originates from the water molecules located in the binding pocket, the water molecules outside the binding pocket also affect the calculated λmax mainly by causing a reorganization of the protein structure. The results reported in this study can be used for the evaluation and further development of hydration methodologies, in general, and rhodopsin QM/MM models, in particular.

Computational chemistry provides versatile methods for studying the properties and functioning of biological systems at different levels of precision and at different time scales. The aim of this article is to review the computational methodologies that are applicable to rhodopsins as archetypes for photoactive membrane proteins that are of great importance both in nature and in modern technologies. For each class of computational techniques, from methods that use quantum mechanics for simulating rhodopsin photophysics to less-accurate coarse-grained methodologies used for long-scale protein dynamics, we consider possible applications and the main directions for improvement.

Molecular mechanisms of adaptation to the habitat depth in visual pigments of A. subulata and L. forbesi squids: on the role of the S270F substitution. Journal of Integrated OMICS, 9(1), pp.44-50. (Ph.D. Ryasantsev M.N.)

Revealing the mechanisms of animal adaptation to different habitats is one of the central tasks of evolutionary physiology. A particular case of such adaptation is the visual adaptation of marine species to different depth ranges. Because water absorbs more intensively longer wavelengths than shorter wavelengths, the increase of habitat depth shifts the visual perception of marine species towards the blue region. In this study, we investigated the molecular mechanisms of such visual adaptation for two squid species – Alloteuthis subulata and Loligo forbesi. These species live at different depths (200 m and 360 m, respectively) and the absorption maximum of A. subulata visual rhodopsin is slightly red-shifted compared to L. forbesi rhodopsin (499 and 494 nm, respectively). Previously, the amino acid sequences of these two species were found to differ in 22 sites with only seven of them being non-neutral substitutions, and the S270F substitution was proposed as a possible candidate responsible for the spectral shift. In this study, we constructed computational models of visual rhodopsins of these two squid species and determined the main factors that cause the 5 nm spectral shift between the two proteins. We find that the origin of this spectral shift is a consequence of a complex reorganization of the protein caused by at least two mutations including S270F. Moreover, the direct electrostatic effect of polar hydroxyl-bearing serine that replaces non-polar phenylalanine is negligible due to the relatively long distance to the chromophore.

Perspective tools for optogenetics and photopharmacology: from design to implementation. In Progress in Photon Science (pp. 139-172). Springer, Cham. (Ph.D. Ryasantsev M.N.)

Optogenetics and photopharmacology are two perspective modern methodologies for control and monitoring of biological processes from an isolated cell to complex cell assemblies and organisms. Both methodologies use optically active components that being introduced into the cells of interest allow for optical control or monitoring of different cellular processes. In optogenetics, genetic materials are introduced into the cells to express light-sensitive proteins or protein constructs. In photopharmacology, photochromic compounds are delivered into a cell directly but not produced inside the cell from a genetic material. The development of both optogenetics and photopharmacology is inseparable from the design of improved tools (protein constructs or organic molecules) optimized for specific applications. Herein, we review the main tools that are used in modern optogenetics and photopharmaclogy and describe the types of cellular processes that can be controlled by these tools. Although a large number of different kinds of optogenetic tools exist, their performance can be evaluated with a limited number of metrics that have to be optimized for specific applications. We classify these metrics and describe the ways of their improvement.

Controlled liquid-phase synthesis of new metal-organic frameworks. Project leader – Dr. Andrey S. Mereshchenko

The synthesis and study of the properties of metal-organic frameworks is one of the most rapidly developing areas of modern coordination chemistry. The synthesis of metal-organic frameworks is affected by numerous factors, such as the nature of organic linkers, properties of metal ion, pH value, duration of the synthesis, temperature, solvent, and the ratio of reagents.

In our laboratory, we develop a number of methods for the synthesis of these substances, such as the slow evaporation method, the solvothermal autoclave method, and the direct precipitation method. We study metal-organic frameworks based on ions 3d- (Co, Cu, Zn) and 4f-elements (Eu, Tb, Gd, Lu) coordinated with organic linkers (1,2- and 1,4-benzenedicarboxylate anions and corresponding acids, 4,4'-bipyridine) in individual (water, ethanol, dimethylformamide, dimethyl sulfoxide, dimethylacetamide) and mixed solvents. In addition to synthesis, our group is actively studying the equilibrium processes of complex formation, the kinetics and mechanisms of nonequilibrium processes in solution that lead to the formation of metal-organic frameworks. Particular attention is paid to the synthesis and analysis of luminescent metal-organic framework structures based on complexes of europium (III) and terbium (III) with aromatic carboxylic acids (for example, terephthalic acid).

Synthesis of new nanocrystalline luminescent materials based on rare earth compounds. Project leader – Dr. Andrey S. Mereshchenko

Nowadays, luminescent materials are widely used in science, technology, and medicine. Nanocrystalline luminescent materials are actively used in medicine and biotechnology as luminescent labels for studying the structure of cells and diagnosing diseases. Particularly, upconverting luminescent materials (substances that emit light at a higher frequency than the absorbed light) are used as biomarkers, fluorescent sensors, infrared visualizers, luminescent security signs for documents and banknotes. Many rare earth compounds have pronounced luminescent properties. It is known from the literature that among the compounds of rare-earth elements, fluorine-containing compounds, for example, ReF₃ or NaReF₄, exhibit the brightest luminescence, and the crystalline phase and morphology of particles critically affect the luminescence properties.

In our laboratory, we synthesize nanocrystalline phosphors with mixed crystal matrix including down-converting (NaY_xGd_yEu_zF₄, NaY_xLu_yEu_zF₄, NaY_xGd_yTb_zF₄, NaY_xLu_yTb_zF₄) and up-coverting (NaY_xGd_yYb_zTm_kF₄, NaY_xLu_yYb_zTm_kF₄, NaY_xGd_yYb_zEr_kF₄, NaY_xLu_yYb_zEr_kF₄) luminescent materials and study the effect of concentration of the initial reagents and the synthesis conditions on the luminescence intensity. Synthesis is usually carried out by the hydrothermal method in an autoclave at the temperature of 180 degrees Celsius. We study the qualitative and phase composition of the materials as well as the size and shape of the particles.

Ultrafast photochemistry and spectroscopy of coordination compounds. Project leader – Dr. Andrey S. Mereshchenko

Photoactive complexes of transition metals play important roles in biological processes and are actively used in various branches of science and technology. For example, copper-containing proteins play a key role in the process of photosynthesis. Compounds of platinum, iridium, osmium, and other metals of the second and third transition series are often used for anti-cancer photodynamic therapy.

In our laboratory, we the study of the photochemistry of transition metal complexes in solution with a high temporal resolution (10^-13-10^-6 s). The dynamics of excited states and photochemistry of complexes of copper, chromium, platinum, iridium, and other transition metals are studied using time-resolved transient absorption spectroscopy. Using this method, photo-initiated physical and chemical processes are with a time resolution of up to 15 fs, a time comparable to the period of molecular vibrations. In addition, the thermodynamics and kinetics of complex formation processes in solution are studied. To explain the experimental data, we also perform quantum chemical calculations.

Mikhaylov, V.N., Panov, M.S., Khairullina, E.M., Melnik, M.V., Kochemirovsky, V.A., Balova, I.A. “Copper-based nanocatalysts produced via laser-induced ex situ generation for homo- and cross-coupling reactions”, Chemical Engineering Science, 2020, 14, 115940, DOI: 10.1016/j.ces.2020.115940. (Ph.D. Panov M.S.)

In this work, we propose the promising approach that provides conditions for laser-induced ex situ synthesis of Raney-like copper-based nanostructured catalysts. Their catalytic activity and selectivity were investigated in Cu-catalyzed acetylene homo-coupling, Pd/Cu-catalyzed the Sonogashira cross-coupling and Cu-catalyzed azide-alkyne cycloaddition (CAAC). It was found that the growth of particles generated within the focus of the laser beam can last even if laser irradiation is off and can be controlled by adding phenanthroline to the reaction mixture as the stabilizing ligand or by increasing its temperature and concentration. Particle size of the synthesized copper-based catalysts significantly affects the reaction selectivity. Thus, it is possible to manage the course of the catalytic reaction towards formation of either homo-coupling or cross-coupling products by changing the size of the catalytically active copper-containing particles produced during laser-induced synthesis.

A simple approach for in situ laser-induced modification of iridium-based materials to increase their electrocatalytic activity towards enzyme-free glucose sensing was proposed. For this purpose, we deposited gold and platinum separately and as a mixture on the surface of pre-synthesized iridium microstructures upon laser irradiation at a wavelength of 532 nm. Then, we carried out the comparative investigation of their morphology, elemental and phase composition as well as their electrochemical properties. The best morphology and, as a result, the highest sensitivity (~9960 µA/mM cm²) with respect to non-enzymatic determination of D-glucose were demonstrated by iridium-gold-platinum microstructures also showing low limit of detection (~0.12 µM), a wide linear range (0.5 µM–1 mM) along with good selectivity, reproducibility and stability.

(Ph.D. Panov M.S.)

In this work, we reported in situ laser-induced synthesis of sensor-active copper‑silver microcomposite. This bimetallic microelectrode exhibits highly developed surface area and good electrical conductivity, and can be successfully used for glucose and alanine sensing demonstrating decent sensitivity (31,000 μА cm⁻² mМ⁻¹ for d-glucose and 11,177 μА cm⁻² mМ⁻¹ for l-alanine) and low limit of detection (2.8 μM for d-glucose and 0.83 μM for l-alanine). High sensor activity and good electrochemical characteristics of the synthesized material can be associated with the eutectic type of the Cu-Ag system. The implemented technique is quite useful for fabrication of new promising small size sensors for enzymeless determination of different biological analytes.

(Ph.D. Panov M.S.)

In the current paper, in situ laser-induced synthesis of gas sensing microcomposites based on molybdenum and its oxides is discussed. The influence of pH of the solutions used for deposition and optical characteristics of a dielectric substrate on electrical conductivity and sensor properties of the synthesized microdeposits is also studied. It was shown that the phase distribution in the obtained materials is consistent with temperature level in the thermal zones of the laser beam focused on the surface of a dielectric substrate of different type. In turn, highly developed surface area of these microsensors is directly responsible for their high sensitivity, short response time, and low temperature of regeneration with respect to hydrogen sulfide and ammonia. Indeed, the highest sensitivity was observed for detection of small concentration (≤50 ppm) of hydrogen sulfide at temperatures of 300–350 °C, whereas at temperatures of 300 °C or less, the deposited molybdenum-containing microstructures are applicable for the ammonia sensing. Thus, this work demonstrates that the method of laser-induced metal deposition is a promising and perspective approach for fabrication of new effective standalone micro-sized gas sensors.
