Comparing MRI and arthroscopic appearances of common knee pathologies: A pictorial review
Authors: Lamour Richard J. , Patel Nikhil N. , Harris Griffin B. , England Jonathan S. , Lesniak Bryson P. , Kaplan Lee D. , Jose Jean
Published: May 2024

Knee pathology, including anterior cruciate ligament (ACL) tears, meniscal tears, articular cartilage lesions, and intra-articular masses or cysts are common clinical entities treated by orthopedic surgeons with arthroscopic surgery. Preoperatively, magnetic resonance imaging (MRI) is now standard in confirming knee pathology, particularly detecting pathology less evident with history and physical examination alone. The radiologist’s MRI interpretation becomes essential in evaluating intra-articular knee structures. Typically, the radiologist that interprets the MRI does not have the opportunity to view the same pathology arthroscopically. Thus, the purpose of this article is to illustratively reconcile what the orthopedic surgeon sees arthroscopically with what the radiologist sees on magnetic resonance imaging when viewing the same pathology. Correlating virtual and actual images can help better understand pathology, resulting in more accurate MRI interpretations. In this article, we present and review a series of MR and correlating arthroscopic images of ACL tears, meniscal tears, chondral lesions, and intra-articular masses and cysts. Short teaching points are included to highlight the importance of radiological signs and pathological MRI appearance with significant clinical and arthroscopic findings.

Published: May 2024

Nonradiative transitions are changes in energy states in atoms, ions or molecules that do not involve the emission or absorption of photons. Despite their importance in understanding luminescent properties and photochemical reaction mechanisms, nonradiative transitions are rarely given more than a qualitative overview in undergraduate and even graduate physical chemistry curricula. To supplement the coverage of nonradiative transition topics, we provide here a set of active learning exercises to help students develop an intuitive understanding of the factors that determine the rate of nonradiative transitions. We start by outlining the theoretical background through the formulation of the Franck-Condon factor and its relation to the rate of nonradiative transition. We then introduce three teaching modules, with associated MATLAB and Python codes, to explore how 1) the excited state nuclear displacement, 2) the electronic energy gap between excited and ground state, and 3) the excited/ground state vibrational mode frequencies affect the magnitude of the Franck-Condon factor and thereby the rate of nonradiative transitions. The wavefunction overlap plots that accompany all teaching modules provide direct visualization of the effect of input parameters on the magnitude of Franck-Condon overlap integral.
Can qualitative non-target data be indicative of PFAS contamination? First evidence by correlation with EOF in environmental samples
Authors: Zweigle Jonathan , Simon Fabian , Meermann Björn , Zwiener Christian
Published: May 2024

We combined and correlated non-target screening (NTS) features and extractable organic fluorine (EOF) data for PFAS analysis in environmental samples. Soils, sediments, and ashes from different locations (Germany, France, Lithuania) (n=34) were extracted and analyzed via liquid chromatography-high-resolution mass spectrometry (LC-HRMS) and high resolution-continuum source-graphite furnace molecular absorption spectrometry (HR-CS-GFMAS). NTS feature prioritization based on the mass to carbon (m/C) and mass defect to carbon (MD/C) ratio was applied to discriminate potential PFAS features from common co-extracted organic matrix. Our results show a high correlation between quantitative EOF data with the prioritized feature number (R2 = 0.87, rPearson = 0.93) as well as with the total peak area of prioritized features (R2 = 0.97, rPearson = 0.98) while commonly applied MD-ranges for filtering showed much weaker correlation with EOF. The observed highly significant correlations highlight that MD/C-m/C prioritization is associated with a good indication of the overall PFAS burden as evidenced by EOF. Also, semi-quantitative data can be extracted from PFAS-specific NTS as shown for the EOF vs. prioritized peak areas. The correlations indicate that lowly fluorinated compounds were negligible and that the EOF was mostly composed of higher fluorinated substances. We recommend further investigation of the unique complementary EOF vs. NTS combination for PFAS screening.

Interface engineering remains a largely underexplored area and yet it holds the keys to high performance Li-ion batteries. It is the charge transfer across electrode-electrolyte interfaces, its inefficient energetics and sluggish kinetics that are oftentimes significant obstacles for achieving fast charging and high power regimes without compromising battery lifespan. This work propose a Boltzmann-averaged first principles workflow based on constant potential and constrained density functional theory for estimation of atomic scale factors influencing coupled ion-electron charge transfer kinetics across battery electrode-electrolyte interfaces. The approach estimates diabatic Li+ interface energy landscapes as function of the interface character and operational conditions, needed to simulate charging/discharging currents. Experimental trends for the LixCoO2 (0.5≤x≤1.0) electrode in varied organic electrolytes with LiPF6 and LiClO4 salts are reproduced, identifying Li+ transfer energy and Li+ adsorption energy as decisive factors influencing the enhanced kinetics in LiClO4-based electrolytes over LiPF6, rationalized by a stronger surface interaction of ClO4-.
Large Language Models as Molecular Design Engines
Authors: Bhattacharya Debjyoti , Cassady Harrison , Hickner Michael , Reinhart Wesley
Published: May 2024

The design of small molecules is crucial for technological applications ranging from drug discovery to energy storage. Due to the vast design space available to modern synthetic chemistry, the community has increasingly sought to use data-driven and machine learning approaches to navigate this space. Although generative machine learning methods have recently shown potential for computational molecular design, their use is hindered by complex training procedures, and they often fail to generate valid and unique molecules. In this context, pre-trained Large Language Models (LLMs) have emerged as potential tools for molecular design, as they appear to be capable of creating and modifying molecules based on simple instructions provided through natural language prompts. In this work, we show that the Claude 3 Opus LLM can read, write, and modify molecules according to prompts, with an impressive 97% valid and unique molecules. By quantifying these modifications in a low-dimensional latent space, we systematically evaluate the model’s behavior under different prompting conditions. Notably, the model is able to perform guided molecular generation when asked to manipulate the electronic structure of molecules using simple, natural-language prompts. Our findings highlight the potential of LLMs as powerful and versatile molecular design engines.
Cathodic Decomposition Electrodes (CDEs) As Standard Reference Electrodes for Molten Salts: Example of the Lithium Eutectic Electrode (LEE) for the LiCl-KCl Eutectic
Authors: Lichtenstein Timothy , Schvaneveldt Mark , Gesualdi Jarrod , Hawthorne Krista
Published: May 2024

Alternatives to the widely-used standard anodic decomposition reference electrodes in molten salts are necessary to enable more easily reproduced thermochemical and electrochemical data in molten salt electrolytes. The class of standard reference electrodes called cathodic decomposition electrodes (CDEs) are easily constructed and can be used to make thermochemical measurements in molten salts more directly compared to anodic decomposition electrodes. The lithium eutectic electrode (LEE) was chosen as a sample test case for validation and was applied to thermochemical measurements of electroactive species in molten LiCl-KCl eutectic. Transient measurements were made to measure the Li+ /Li reduction potential at zero current in pure LiCl-KCl eutectic relative to a Li-alloy reference electrode to validate the reference potential of the LEE. Literature-reported electromotive force (emf) measurements against Li-alloy reference electrodes were used to generate a relationship between the LEE and the standard chlorine electrode (SClE) and this relationship was used to evaluate measured and reported formal potential measurements for the LiCl-KCl-GdCl3 system. This work demonstrates the general framework for defining CDEs for any molten salt system and a method for calibrating external reference electrodes against a CDE standard reference electrode, improving the ease of obtaining thermochemical and electrochemical measurements in any molten salt system.

Published: May 2024

We demonstrate that 2-alkenylarylaldimines and ketimines undergo thermal 6pi-azaelectrocyclization to generate a wide range of azabicyclic o-quinodimethanes (o-QDMs). These o-QDMs exist as a hybrid of a diene and a benzylic diradical. The diradical nature was confirmed by their ability to undergo dimerization and react with H-atom donor, TEMPO and O2. In addition, the interception of the diradicaloid o-QDMs by H-atom transfer was used to synthesize five tetrahydroisoquinoline alkaloids and related bioactive molecules. The diene form can undergo [4 + 2] cycloaddition reactions with different dienophiles to generate bridged azabicycles in high endo:exo selectivity. The azabicyclic o-QDMs can be generated for [4 + 2] cycloaddition from a wide range of electronically and sterically varied 2-alkenylarylimines, including mono, di, tri and tetrasubstituted alkenes, and imines derived from arylamine, alkylamine (1°, 2°, 3°), benzylamine, benzylsulfonamide and Boc-amine.

Published: May 2024

Fullerenes, with well-defined molecular structures and high scalability, hold promise as fundamental building blocks for creating novel carbon materials. The fabrication and transfer of large-area films with precisely controlled thicknesses and morphologies on desired surfaces are crucial for designing and developing new fullerene-based materials and devices. In this work, for the first time, we present strategies for solid-state transferring C60 molecular nanometre-thin films, with dimensions of centimetres in lateral size and thicknesses controlled in the range of 1–20 nm, onto various substrates. Furthermore, we have successfully fabricated centimetre-wide graphene/C60/graphene heterostructures through layer-by-layer stacking of C60 and graphene films. This transfer methodology is versatile, allowing for the complete transfer of chemically modified C60 films, including oxygenated C60 films and C60Pdn organometallic polymer films. Additionally, direct solid-state transfer of C60 and C60Pdn films onto electrode surfaces has enabled their electrocatalytic performance for the hydrogen evolution reaction to be probed directly. This thin-film transfer strategy facilitates the facile preparation and transfer of large-area C60 films, offering a distinct platform for fullerene chemistry and experimental synthesis of novel carbon structures.

Authors: Rachmawati Nur Layli
Published: May 2024

PT Gagas Energi Indonesia is a company engaged in the trading and natural gas business, one of which is Gaslink C-Cyl. Route determination for Gaslink C-Cyl distribution is carried out subjectively based on the proximity of locations between customers, thus creating inefficient routes, affecting the number of vehicles needed, and causing high transportation costs. Based on this problem, this study aims to minimize transportation costs by determining the optimal route and number of vehicles needed using the Multi-Trip Vehicle Routing Problem Time Windows Simultaneous Pickup and Delivery (MTVRPTW-SPD). This problem is solved using Geographic Information System (GIS) based optimization. To evaluate GIS-based optimization performance, comparison between existing condition and optimization are done for 50 demand points. Then, two scenario was developed, 100 and 200 demand points to explain the decision implication related to demand uncertainty. Based on the optimization process for 50 demand points gives better solution than existing condition in term of number of fleets needed, total distance travelled, and total transportation cost which result 3 units, 46,5%, and 43,5% respectively.

Authors: Daniel Christian Gerald , Firdaus Fadhil M. , Imanuella Mazmuria Irene
Published: May 2024

This paper compares the life cycle costs (LCC) of various asphalt mixture technologies added with polymeric substances that modify either the binder or the whole mix and evaluates the hotspot of each mix type with the scope of cradle-to-gate from the raw materials purchase to the production of 7 kg samples. The polymer-modified binder yields the largest total cost of IDR 12,197, followed by the polymer-modified warm and hot asphalt mixture with a difference of up to 3% and 14.5%, and the standard hot mix gives the lowest result (IDR 9,344) of 23.4% smaller than the largest. Raw material price holds the major contribution with approximately 82.7%, while electricity consumption accounts for 30%. Oven heating contributes the most to the calculated impact from the lab production by 40 to 60%, followed by the mixing activity by a 10 – 30% difference. Conclusively, the LCC of bituminous mixture production is heavily influenced by raw materials price and electricity consumption, and the standard hot mix asphalt generates the lowest total cost, despite having a higher cost than the warm mix in the production stage.
A study on financial literacy of students
Authors: Shanmugha Priya P.
Published: May 2024

One of the causes of financial crises is identified as lack of financial literacy. India, a developing country, is entering the second phase of financial sector reforms. The integration of the economy with the world economy will increase further, with the risk of a world crisis impacting the Indian economy. In India, there is a large unorganized sector, and the government is withdrawing from pension schemes even in the organized sector. In the absence of any social security scheme, the Indian economy will be in a state of major instability after the demographic dividend starts decreasing after 20 or 25 years. Thus, the improvement of financial literacy in the country is imperative for the financial well-being of individuals and for the economy. The significance of financial literacy as a transformation agent on the financial inclusion agenda of the nation is undisputed in academic and practitioner circles. This paper provides a review of the definitional and measurement aspects of financial literacy, and an attempt is made to identify the various aspects involved in defining and measuring financial literacy in India. The researcher examined the level of financial literacy of collegegoing students and analyzed their financial behavior using mean score analysis. The research found that the borrowing behaviors of the students are high, and their interest in learning the life skill of financial management is also high.

Living in a Condominium Regime: Neighborhood Conflicts in Low-Income Housing, Tijuana, Baja California – A Secondary Publication
Authors: Zárate López M. , Almejo Ornelas A. , Sahagún Valenzuela M.
Published: May 2024

This paper analyzes neighborhood conflicts arising from the condominium property regime, under which social housing promoted by Mexican government institutions and private developers is acquired. This regime has facilitated access to housing for the salaried population, but it is far from contributing to the attainment of the right to housing. The research takes as case studies housing complexes located in the city of Tijuana, Baja California, Mexico. The analysis included a mixed methodology. Firstly, similar case studies were analyzed; secondly, a review of the Condominium Property Regime Law was carried out in order to understand its implications. In view of the pandemic situation, a virtual survey was applied to the inhabitants of these areas, as well as interviews with presidents of neighborhood committees of these complexes. From the above, it was found that this form of ownership generates conflicts, reflected in the dissatisfaction of the inhabitants with their housing, disagreements and controversies in their organization and coexistence. The inhabitants have to collectively solve the problems they face, related to the maintenance and use of common areas, insecurity, and cleanliness, among others. In addition, there is a lack of support from local authorities. With this, it is concluded that although the inhabitants have a space that solves their housing problem, it does not manage to be a space that adequately guarantees their right to housing.

Authors: Karaıbrahımoglu Adnan , Kara Ümit , Kılıçoğlu Özge , Kara Yağmur
Published: May 2024

Objective: The aim of the study is to predict the absorbed radiation dose on thorax CT imaging in geriatric patients with COVID-19.
Materials and Method: The SIEMENS SENSATION 64 CT scanner was performed with real protocols to patients (male/female phantom) using Monte Carlo simulation methods with the patient’s real height and weight nts and the actual parameters CT scanner. Absorbed organ doses have been calculated based on these Monte Carlo results. These results were used to predict the optimal absorbed radiation dose by Artificial Neural Network, Linear Discriminant Analysis, Random Forest Classification, and Naive-Bayes Classification algorithms. The dose values were clustered for genders by the Fuzzy C-Means algorithm.
Results: The ages of the patients were between 60 and 70 years. The Body Mass Indexes of male and female patients were 26.11 ± 4.49 and 25.03 ± 4.86 kg/m2 respectively. All classification algorithms were validated with approximately 100% success. The Fuzzy C-Means technique was found to be successful in clustering the dose values for gender clusters.
Conclusion: While the predicted and the observed values of patients do not change in the organs/tissues around and outside of the thorax, they generally vary in the intra-thoracic organs and tissues. It can be concluded that data-driven techniques are useful to obtain optimal radiation doses for organs/tissues in CT imaging.
A novel method for measuring and improving the dehumidification process inside a direct contact condensation unit
Authors: Kuru Funda , Kumlutaş Dilek
Published: May 2024

This paper reveals some of the experimental results retained during the comprehensive experimental research on the direct contact dehumidification process in a washer dryer machine. Pressurized spray water is injected into the moist air subject to dehumidification; the interplay between the saturated water droplet and process air leads to direct contact condensation occurring on the droplet surface. As a result, latent heat of condensation is released, and saturated water temperature increases. This study investigates the detailed interaction between these two streams and evaluates the effects of temperature distribution with the elapsed time over the moisture removal rates. Results show that numerical results are generally in line with the experimental work, which proves the applicability of the Computational Fluid Dynamic (CFD) solutions to this tedious system modelling process.
ARTE Y GEOLOGÍA.
Authors: Meseguer Mayoral Rosell
Published: May 2024

Resumen
Los métodos sin teoría son impensables en la creación artística; la teoría y la práctica no son contrarias, sino complementarias. En 1878 la fotografía posibilitó la descomposición del movimiento, y con este hecho muchas ideas se revelaron erróneas. Muybridge, pudo comprobar que los cuatro cascos de una yegua despegaban del suelo a la vez, lo que contradecía las ideas vigentes hasta entonces. Estos estudios científicos y técnicos incidieron en artistas como Degas, Puvis de Chavannes o Rodin, evidenciando la estrecha relación entre arte, ciencia y tecnología. A partir de esta introducción el texto describe diversos proyectos de arte que vengo realizando desde 2005, entre artes visuales y geología. Se explican los métodos de investigación artística, la metodología teórica, la idea o el concepto, y la metodología práctica, la materialización de esa idea en las artes plásticas y su estrecho vínculo con la geología y otras ciencias de la naturaleza.
Sí hay trabajo: ejercicios performáticos para la resignificación de lo doméstico
Authors: Rosero Andrade Glenda
Published: May 2024

Históricamente, se han ubicado a las tareas domésticas como actividades relegadas del campo de producción. Su territorialización al ámbito de la reproducción, espacio asociado habitualmente con lo femenino, ha determinado el despojo de su valor económico y social. Sin embargo, discursos contemporáneos instan al reconocimiento de la importancia de estas tareas y su redistribución genérica. En este sentido, las artes visuales han sido una plataforma potente para subvertir el discurso tradicional y contribuir con nuevos enfoques. Articulado a ello, el Colectivo Maternas realiza Sí hay trabajo, una propuesta performática que visibiliza la importancia del espacio doméstico a partir de la aplicación de elementos asociados con la productividad, para reubicar simbólicamente las actividades realizadas en este ámbito y legitimarlas como ingreso en especie.
Cuerpo, bioerotismo y ciberespacio en las performatividades ecocríticas de David Crononberg, Julio Huayamave y David Jara

Published: May 2024

Uno de los desafíos fundamentales para asumir las transformaciones de toda índole de cara a una crisis global es cambiar el vínculo que mantenemos con la naturaleza, y ello comporta, en primer lugar, analizar cómo nos relacionamos entre humanos. David Cronenberg, Julio Huayamave y David Jara comparten en común la performatividad de sus poéticas visuales que observan al cuerpo vinculado a una perjudicial noción bio-robótica; sus alegorías tienen un carácter ecocrítico y son nihilistas respecto al supuesto progreso tecnológico. Estos autores abordan la anulación de lo humano ante su contendiente transhumano, así como la desconfiguración de lo comunitario como ámbito donde, en algún momento, imaginamos redimirnos y avanzar.

Poéticas del azul y políticas del color en la obra de Seba Calfuqueo
Authors: Veraguas Caripan Ignacio
Published: May 2024

El color es uno de los elementos formales más relativos en las piezas de arte y, quizás, uno de los aspectos menos atendidos en las prácticas artísticas contemporáneas. En este escrito busco reflexionar sobre el color azul en la obra de Seba Calfuqueo, artista mapuche contemporánea. Kallfü es la palabra en mapudungun que designa el azul y contiene una dimensión sagrada y simbólica, evocada en distintos momentos visuales en las obras de la artista. A partir de esta constatación, propongo una reflexión sobre la poética común e insistente en torno al azul en Calfuqueo. Sugiero que la decisión estética del azul puede ser leída a partir de al menos dos posicionamientos: (1) como relectura del sentido del kallfü a partir de las condiciones históricas actuales; (2) en su sentido performático, como modo de aparición alterna a la coloración de la blanquitud que constituye el ethos moderno.
Lo que el óleo me enseñó sobre epistemología
Authors: Vega de la Torre Hugo Alejandro
Published: May 2024

En este ensayo se expone la relación entre las cualidades materiales de la pintura y su afinidad con la investigación artística. El objetivo es señalar en las características del óleo, en sus manchas imprecisas, irrepetibles e indefinibles, atisbos de una epistemología que lo mismo reconoce a la certeza y a la incertidumbre como elementos que configuran el conocimiento.

Authors: Faria Robson Alves , Tinti Douglas da Silva
Published: May 2024

Trata-se de um estudo cujo objetivo é analisar as repercussões da atuação de um preceptor de Matemática no processo de constituição de sua identidade como formador. Este preceptor leciona Matemática em uma escola estadual e atuou como preceptor no subprojeto de Matemática da Universidade Federal de Ouro Preto. Os dados foram produzidos a partir de uma entrevista semiestruturada. Após a transcrição, a análise foi realizada à luz da caracterização da Identidade Profissional de Professor que Ensina Matemática, proposta por Cyrino (2017). Assim, os eixos que nortearam a análise foram: emoções, crenças e concepções; conhecimento; autoconhecimento; autonomia (vulnerabilidade e o sentido de agência) e compromisso político. Considerando aspectos como a dinamicidade e a experiencialidade, os dados revelaram que o Programa Residência Pedagógica possibilitou ao professor da escola uma atuação nova (preceptor) que mobilizou um deslocamento para constituição da sua identidade como de formador de professores.

The increase in the fleet of motor vehicles circulating in urban centers is one of the main generators of gaseous pollutants harmful to human health and the environment. Pollutants can be economically and effectively monitored through passive sampling. This study aims to estimate NO2 levels on roads of Fortaleza city /CE using the passive sampling method. 12 campaigns covered the rainy (March-June) and the dry (July-November) seasons in 2019. The seasonal averages of NO2 in the rainy season were higher than the dry one, and Almirante Rubim Street showed the greatest difference in the averages: 26.6 µg m-3 in the rainy and 19.3 µg m-3 in the dry season. The principal component analysis applied to the averages of NO2 concentration in the rainy and dry seasons, vehicle traffic and Height of the road/width ratio indicated that components 1, 2 and 3 explain 94.4% of the studied cases. Passive sampling proved to be efficient, contributing to the production of unpublished data about NO2 levels in streets of Fortaleza/Ceará/Brazil from mobile sources.

Published: May 2024

. In the present work, the spatial and electronic structures of the lowest energy conformation of the carnosine N1H tautomer in the zwitterionic form, which has a wide range of applications, have been studied. The calculations were performed by the DFT quantum-chemical method based on the B3LYP hybrid functional and the 6-31+G(d,p) basis set in gas, water, and DMSO using the Gaussian 09 and GaussView 6.0.16 programs. The geometry parameters, values of electronic energy, dipole moments, values of partial charges on atoms, HOMO and LUMO energies, descriptors of reactivity of a molecule were calculated and NBO analysis is carried out. The molecular electrostatic potential (MEP) maps and frontier orbitals were visualized. The structural and electronic rearrangements in the molecule and changes in various parameters depending on the dielectric constant of the medium were analyzed. It was found that the influence of the solvent does not play a significant role for this structure, very similar results were obtained for the aqueous medium and DMSO. However, the optimization of the geometry of this carnosine zwitterion tautomer in the gas phase, led to the elimination of the hydrogen atom from the terminal NH3+ group and its addition to the COO- group, actually converting the zwitterionic form into a neutral one.
NITRIC OXIDE IS A HIGHLY EFFICIENT ROS TRAP. POSSIBILITY OF CLINICAL USE FOR DIAGNOSTICS
Authors: Titov V. , Osipov A. , Anankina A. , Kochish I.
Published: May 2024

It has been shown that nitrite is normally present in most tissues at a concentration not exceeding 50 nM. But the tissues contain NO donor compounds in concentration dozens of micromoles. Consequently, there are mechanisms in the tissues that prevent the oxidation of NO to nitrite. The NO donor compounds do not spontaneously dissociate with the release of NO. The transformation of NO included in the composition of donor compounds to nitrite and non-thiolate nitroso compounds (NO2- + RNO) occurs under the action of active oxygen species (ROS) and, above all, superoxide that is produced by activated phagocytes. Thus, the content of NO2- + RNO is a very sensitive indicator of phagocyte activation, a process that accompanies any inflammation. In this paper, the possibility of using the NO2- + RNO content as indicator for the early diagnosis of inflammatory diseases is considered. It has been shown that this indicator has greater sensitivity and specificity than all known clinical and biochemical indicators. This makes it especially valuable for monitoring the state of patients in the hospital, monitoring the farm animals. The factor limiting the use of the NO2- + RNO indicator in diagnostics is the permeability of tissue barriers to these compounds. This is especially important for monitoring the condition of the fetus, as well as the state of the central nervous system.
PECULIARITIES OF HEMINE AND ZnII-COMPLEX TETRA(4-PYRIDYL) PORPHYRIN INTERACTION WITH HEXAMOLIBDENICELATE-POLYANION IN AQYEOUS MEDIA
Authors: Klimenko I. , Kitushina E. , Lobanov A.
Published: May 2024

This work presents a method for producing new hybrid supramolecular organic-inorganic systems based on tetrapyrrole compounds (natural and artificially synthesized porphyrins) and hexamolibdenonicelate anion to create highly ordered supramolecular complexes based on porphyrins with the possibility of using them in medicine. In particular, the reaction of natural porphyrin (hemin) and the ZnII-complex of tetra(4-pyridyl)porphyrin with the heteropoly compound sodium hexamolibdenonicelate crystalline hydrate Na4[Ni(OH)6Mo6O18]·8H2O in an aqueous medium is considered. This heteropoly compound due to its physicochemical and biological properties can be considered as a part of photochromic materials and pharmacological agent. The optical absorption spectra of the obtained hybrid supramolecular organic-inorganic systems were investigated with the help of electronic absorption spectroscopy. Both the transformation of the bands which are the characteristics of porphyrins and the appearance of new bands indicating the formation of hybrid supramolecular organic-inorganic complexes are observed in the electron absorption spectra. The work traces the role of structural features of porphyrins in the process of their interaction with the heteropolyanions. Differences in the spectral behavior of the two metalloporphyrins when interacting them with the heteropoly compound have been shown and explained by variability in their structure. The data obtained will be useful when developing new hybrid materials as antibacterial components for medical use.
