Long-term spatiotemporal features of aerosol optical characteristics and relative humidity in China’s offshore areas

ABSTRACT Marine aerosols are crucial for ocean–atmosphere interactions. However, there is a lack of analysis on the long-term aerosol optical characteristics and relative humidity (RH) based on large-scale ocean regions. This paper addresses this issue by analyzing the spatiotemporal variations of aerosols in China’s offshore waters from 2007 to 2022 using Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and European Centre of Medium-range Weather Forecasts Reanalysis v.5 (ERA5) data. The results show that in the sea area, the aerosol backscatter coefficient at 532 nm and extinction coefficient at 532 nm increase with increasing RH; the aerosol depolarization ratio decreases with increasing RH. The optical properties of aerosols are generally lower in summer, while they fluctuate with rising RH in other seasons. Notably, the values recorded in 2014–2019 were markedly lower than those in 2007–2013. Nevertheless, from 2020 to 2022, the proportion of aerosol types remained largely stable compared to that of 2014–2019, suggesting a negligible impact of the COVID-19 pandemic on emissions, but the near-shore waters’ aerosol optical properties were more sensitive to minor changes than those of far-off waters. After dividing the China’s offshore waters, the overall optical properties of aerosols decreased in order of the Bohai Sea and Yellow Sea, the East China Sea, and the South China Sea, due to the proportion of marine aerosols increase toward the south. After dividing the altitude layer in the sea area, within the range of 0–7 km, the higher the altitude, the less oceanic aerosols and the more terrestrial aerosols. The aerosol depolarization ratio rises, while the aerosol backscatter coefficient at 532 nm and extinction coefficient at 532 nm alternate downwards. We speculate this is linked to the steep decline in total aerosol content as altitude rises. Our results could provide theoretical references for further deepening the understanding of aerosol generation mechanisms in China’s offshore waters.

Local Gradients of Functional Connectivity Enable Precise Fingerprinting of Infant Brains During Dynamic Development.

Brain functional connectivity patterns exhibit distinctive, individualized characteristics capable of distinguishing one individual from others, like fingerprint. Accurate and reliable depiction of individualized functional connectivity patterns during infancy is crucial for advancing our understanding of individual uniqueness and variability of the intrinsic functional architecture during dynamic early brain development, as well as its role in neurodevelopmental disorders. However, the highly dynamic and rapidly developing nature of the infant brain presents significant challenges in capturing robust and stable functional fingerprint, resulting in low accuracy in individual identification over ages during infancy using functional connectivity. Conventional methods rely on brain parcellations for computing inter-regional functional connections, which are sensitive to the chosen parcellation scheme and completely ignore important fine-grained, spatially detailed patterns in functional connectivity that encodes developmentally-invariant, subject-specific features critical for functional fingerprinting. To solve these issues, for the first time, we propose a novel method to leverage the high-resolution, vertex-level local gradient map of functional connectivity from resting-state functional MRI, which captures sharp changes and subject-specific rich information of functional connectivity patterns, to explore infant functional fingerprint. Leveraging a longitudinal dataset comprising 591 high-resolution resting-state functional MRI scans from 103 infants, our method demonstrates superior performance in infant individual identification across ages. Our method has unprecedentedly achieved 99% individual identification rates across three age-varied sub-datasets, with consistent and robust identification rates across different phase encoding directions, significantly outperforming atlas-based approaches with only around 70% accuracy. Further vertex-wise uniqueness and differential power analyses highlighted the discriminative identifiability of higher-order functional networks. Additionally, the local gradient-based functional fingerprints demonstrated reliable predictive capabilities for cognitive performance during infancy. These findings suggest the existence of unique individualized functional fingerprints during infancy and underscore the potential of local gradients of functional connectivity in capturing neurobiologically meaningful and fine-grained features of individualized characteristics for advancing normal and abnormal early brain development.

The influence of model position, attractiveness, and consumer body image on consumer attitudes in fashion advertising

Sensory marketing recognizes the significance of physical experiences in product evaluation and consumer decision-making. This study examined the effects of model features in fashion advertising and consumer physical characteristics on consumer attitudes, drawing on embodied cognition theory. In Study 1, consumers completed a Go/NoGo task, recognition task, and product evaluation. Results showed that model position significantly affects consumer attitudes: right-handed people rated the right position better. Additionally, trait body image can influence this position effect. In Studies 2 and 3, we activated and manipulated state body image, respectively, and discovered the interactive effects of model position, model attractiveness, and consumer body image. Individuals with high body image responded positively to highly attractive models on the right, while those with low body image favored right-positioned less attractive models. These findings provide empirical evidence that body image shapes how people’s bodies interact with the world, and provide practical guidance for sensory marketing.

Dancing robots: aesthetic engagement is shaped by stimulus and knowledge cues to human animacy.

Artificial intelligence (AI) and robots are increasingly shaping the aesthetic preferences of art consumers, influencing how they perceive and engage with artistic works. This development raises various questions: do cues to the humanness of the origin of an artwork or artist influence our aesthetic preferences?. Across two experiments, we investigated how the perception and appreciation of dance is influenced by cues to human animacy. We manipulated Agent Form (human-like or robot-like dancer), Belief about Movement Source (human motion capture or computer animation), Source of Choreography (human- or computer-generated), and Belief about Choreography Source (believed to be human- or computer-generated). Results pointed toward agent congruence: In Experiment 1, robot agents were preferred when the movement source was believed to be computer animation. In Experiment 2, robot agents were preferred when the choreography was believed to be computer-generated, while choreographies believed to be human-generated were generally preferred. Participants could not accurately identify the actual source of choreography. These results persisted beyond the effects of age, dance expertise, technological expertise, attitudes toward AI, and perceived familiarity, complexity, evocativeness, technical competence, or reproducibility of the dance. Dance expertise, technological expertise, and attitudes toward AI independently impacted aesthetic judgments. These findings provide insights into the design of robotic dance, highlighting features of dance choreography and audience characteristics that influence aesthetic engagement. To enhance AI-driven creative productions, shaping perceptions will be crucial for better audience reception and engagement.

Enhancing detection of high-level axillary lymph node metastasis after neoadjuvant therapy in breast cancer patients with nodal involvement: a combined approach of axilla ultrasound and breast elastography.

To develop a combined approach using shear wave elastography (SWE) and conventional ultrasound (US) to determine the extent of positive axillary lymph nodes (LNs) following neoadjuvant therapy (NAT) in breast cancer patients with nodal involvement. This prospective, multicenter study was registered on the Chinese Clinical Trial Registry (ChiCTR2400085035). From October 2018 to February 2024, a total of 303 breast cancer patients with biopsy-proven positive LN were enrolled. The conventional US features of axillary LNs and SWE characteristics of breast lesions after NAT were analyzed. The diagnostic performances of axilla US, breast SWE, and their combination in detecting residual metastasis in axillary level III after NAT were assessed. Pathologically positive LN(s) in axilla level III were detected in 13.75% of cases following NAT. The kappa value for the axilla level with positive LN confirmed by surgical pathology and detected by US is 0.39 (p < 0.001). The AUC of conventional axilla US to determine the status of axilla level III LNs after NAT was 0.67, with a sensitivity of 51.52%, a specificity of 74.36%. The breast SWE displayed moderate performance for detecting residual metastasis in axilla level III following NAT, with an AUC of 0.79, sensitivity of 84.85%, and specificity of 74.36%. Compared to axilla US and breast SWE alone, the combination of axilla US with breast SWE achieved a stronger discriminatory ability (AUC, 0.86 vs 0.67 vs 0.79, p < 0.05, Delong's test) and precise calibration (X2 = 13.90, p = 0.085, HL test), with an improved sensitivity of 93.94% and a comparable specificity of 75.64%%. SWE outperformed conventional US in identifying the axilla levels with nodal metastasis following NAT in patients with initially diagnosed positive axilla. Furthermore, combining breast SWE with axilla US showed good diagnostic performance for detecting residual metastasis in axilla level III after NAT.

Mechanical behaviour and subsurface characteristics of Ti-6Al-4V subjected to electropulsing-assisted multiple laser shock processing impacts

Electropulsing (EP)-assisted laser shock peening (LSP), involving the synchronous application of EP and LSP to Ti-6Al-4V samples, represents an innovative surface strengthening technology. A comprehensive series of evaluations and examinations were conducted to thoroughly investigate the effects of EP-assisted multiple laser shock processing impacts on the mechanical behaviour and subsurface characteristics of the Ti-6Al-4V sample. The strength and ductility properties, fatigue performance, microstructure features in subsurface regions and deformation characteristics at various depths of the treated Ti-6Al-4V samples were investigated. The results revealed that as the number of impacts increased, a prominent multilayered structure, including a remelting layer, a severe plastic deformation region, and a plastic deformation-affected zone in the subsurface developed. The observed increase in strength can be attributed to grain refinement, an increase in dislocation density and the presence of high-density nanotwins within the subsurface layer. A high fatigue life was achieved by EP-assisted multiple LSP, with a ∼328.1 % increase compared with that of the as-received sample.The improvement in durability is mainly related to the enhanced subsurface structure acted as a barrier to crack propagation.

Informer-FDR: A short-term vehicle speed prediction model in car-following scenario based on traffic environment

Drivers’ car-following behaviors on urban roads are influenced by various factors, including pedestrians, cyclists, adjacent vehicles, and roadside parking. However, few models consider these factors’ influence on drivers’ speed selections during car-following, limiting the human-like driving capability of advanced driver assistance systems (ADAS). This paper proposes a vehicle speed prediction model in car-following scenario that considers the influences of the traffic environment. The vehicle speed is predicted using Informer-FDR (Informer with fusion features, dilated causal convolution, and residual connection), which adopts an improved encoder-decoder structure based on the Informer model. Fusing features of traffic environment characteristics and vehicle dynamics parameters enables the dynamic interaction characteristics between drivers and the traffic environment and potential traffic conflicts to be effectively reflected, which enhances the model’s understanding of the complex driving environment. Moreover, the high computational complexity is reduced by using the ProbSparse self-attention mechanism, which will help to address the difficulty of applying Transformer class models to on-board platforms. Totally 3,980 car-following cases were extracted from naturalistic driving data (NDD), vehicle dynamics parameters and traffic environment characteristics in the car-following scenarios were obtained through target detection and ranging algorithm. The optimal feature set was mined using the combined feature selection method. The dilated causal convolution and average pooling layer are introduced to expand the receptive field of the model, enhance global feature extraction, and ensure the causality of temporal predictions. Furthermore, the residual connection was added to the encoder, realizing the direct deep transfer of cross-layer information. Verifications on the test set show that Informer-FDR has the lowest MAE (0.583), MSE (2.942), RMSE (1.715), and the highest speed prediction accuracy (97.76%), spacing gap accuracy (94.27%), acceleration accuracy (95.35%), which outperforms other baseline models in terms of prediction performance. The ablation study confirms the importance of the improved distilling layer module, residual connection module, and fusion features for predictive performance improvement. Additionally, the road-type experiment reveals performance differences of the model on different road types, emphasizing the importance of incorporating traffic environment on urban road.

Two New 2p–3d Metal Complexes with a Nitronyl-Nitroxide Ligand Derived from o-Vanillin: Synthesis, Crystals Structures and Magnetic Properties

Two new 2p–3d complexes, (Et3NH)[ML(hfac)2], have been obtained using the nitronyl-nitroxide radical (HL) derived from 2-hydroxy-3-methoxy-5-nitrobenzaldehyde (M = Mn 1; Co 2). The two compounds are isomorphous and their structures consist of anionic mononuclear species, [M(hfac)2L]−, M = Mn 1; Co 2, and triethylammonium cations, Et3NH+. The metal ions adopt an octahedral geometry, being coordinated by phenoxido and aminoxyl oxygen atoms from the ligand and four oxygen atoms from the hexafluoroacetylacetonato (hfac−) ligand. The cryomagnetic behaviors of the two compounds reveal relatively strong antiferromagnetic M(II)-Rad interactions (JMnRad = −191 cm−1, JCoRad = −166 cm−1 with H = −JSMSRad). The EPR spectra (X- and Q-band) of compound 1 below 70 K show the characteristical features of a S = 2 spin system with zero field splitting terms of D = 0.26 cm−1 and E = 0.031 cm−1.

Tertiary lymphoid structures and B-cell infiltration are IPF features with functional consequences.

Recent literature has shown the presence of B cells and autoantibodies in idiopathic pulmonary fibrosis (IPF) which would imply the presence of tertiary lymphoid structures (TLS, sites where the immune response is triggered), yet TLS are not considered features of the histological characteristics of IPF. This study aims to quantify the presence, size, and degree of activation of TLS in biopsied and explanted lungs from patients with early- and late-IPF, never treated with antifibrotics, and relate their presence and activity to the clinical course, disease progression, and lung inflammation. Immunohistochestry for B cells and CD4, CD8, and CD45 cells was performed in lung tissue from IPF patients: 18 at diagnosis (early), 39 explanted (end-stage), and 12 smoking controls. TLS activation was assessed by CD40 expression. Spirometry along 31 (12-72) months of follow-up was used to characterize end-stage IPF as slow progressors or rapid progressors. B cells, along with other inflammatory cells, were higher in early- and end-stage IPF than in controls (p < 0.001). In rapid progressors, all inflammatory cells were higher than in slow progressors (p < 0.05). TLS were present in 100% of early- and end-stage IPF and in 50% of controls. In end-stage IPF, the TLS area and activation score were higher than in early IPF (p < 0.0001; p = 0.005) and controls (p < 0.04; p < 0.002). TLS activation score correlated with FVC decline during follow-up in rapid progressors (r = 0.73; p = 0.007) but not in slow progressors. A prominent B-cell infiltration, along with the presence of TLS, the activity of which correlates with FVC decline, is an important component of IPF from the beginning of the disease, likely playing an important role on its mechanism and progression.

Age-Related Features of Clinical and Neurological Characteristics and Pathogenetic Therapy in Patients with Multiple Sclerosis

INTRODUCTION: Multiple sclerosis (MS) is a neurological demyelinating disease of the central nervous system manifested by pronounced heterogeneous symptoms. Peculiarities of the onset, progression rate, and severity of syndromes are different in different age groups. An increase in the frequency of exacerbations, high degree of disability of patients in different age groups evidence insufficient effectiveness of the conducted pathogenetic therapy. Due to a wide choice of multiple sclerosis disease modifying drugs (MSDMDs), it is important to study the clinical and neurological characteristics of patients with MS in different age groups with the aim of further developing an individual approach to treatment. AIM: To study clinical and neurological features and effectiveness of pathogenetic therapy of MS in patients of different age groups. MATERIALS AND METHODS: A prospective analysis of the data of neurological examination and results of magnetic resonance imaging of 100 patients of different age groups with relapsing-remitting MS, who received outpatient treatment in Kursk Regional Multidisciplinary Clinical Hospital, was conducted in the period of stable remission. RESULTS: The leading syndromes in patients with relapsing-remitting course of MS were cerebellar (78%) and pyramidal (70%) syndromes, besides, dysfunction of the cranial nerves (71%) was also observed. A quantitative parameter of explicitness of pelvic disorder syndrome predominated in middle-aged and elderly patients compared to young ones (p 0.001). Cognitive disorders were more often (14%) recorded in middle-aged and elderly patients (p 0.001). The use of glatiramer acetate permitted to reduce the degree of disability in young subjects (p 0.05); in patients of the middle age group, the most effective was a timely transition from interferon beta to ocrelizumab (p 0.05). The use of first-line MSDMDs (interferon-beta) in elderly patients demonstrated low effectiveness (p 0.05). CONCLUSION: In middle-aged and elderly patients with equal timing of MS onset, the neurological deficit is more expressed than in young ones. First-line pathogenetic therapy, in particular, glatiramer acetate, is more effective in young patients, while patients of middle age are recommended an early transition to second-line MSDMDs.

Technological features of production and quality characteristics of restructured poultry ham with lentil isolate

The article presents the results of research on the technological aspects of producing restructured hams from poultry meat, specifically samples “Chicken Ham” No. 1 and “Turkey Ham” No. 2. The primary objective was to determine the impact of raw material composition and technological parameters on the physicochemical, functional-technological, and organoleptic properties of the final products. The recipe included lentil isolate, starch, mechanically deboned meat (MDM) from chicken and turkey, as well as auxiliary ingredients: salt, coloring agent, sodium tripolyphosphate, sodium nitrite, pepper, and nutmeg. The study found that active acidity (pH) significantly affects the water-binding capacity of the meat mixtures. Sample No. 1 had a 1.6 % higher pH level compared to sample No. 2 and the control, which resulted in lower water- and fat-binding capacities. Meanwhile, sample No. 2 demonstrated the best yield (93.9 %) and the lowest mass loss (6.1 %), indicating the effectiveness of using turkey meat in the formulation. The research also showed an increase in the protein content by 32.44 % (No. 1) and 36.48 % (No. 2) compared to the control. Organoleptic evaluation confirmed the high taste quality of the products, making them suitable for market implementation. Microbiological studies confirmed that the products meet the requirements of regulatory documentation. The results of functional-technological indicators confirmed that sample No. 1 had a higher fat-binding capacity, while sample No. 2 exhibited better moisture retention and product yield. The yield and loss calculations for the restructured hams revealed that sample No. 2 had the highest yield (93.9 %) and the lowest losses (6.1 %), while sample No. 1 showed slightly lower values (90.04 % yield and 9.96 % losses). The study also demonstrated that lentil isolate used in the formulation positively influenced the product yield and its moisture retention ability. Sample No. 1, which contained more starch and lentil isolate, showed a higher moisture retention level but was inferior to sample No. 2 in fat-binding capacity. This suggests that recipe modifications, such as the use of different meat types and auxiliary components, have a decisive impact on the functional-technological characteristics of the hams. Additionally, significant attention was given to the microbiological safety of the test samples, as the production process for hams involves thermal processing. The results of microbiological analysis confirmed that all samples met established regulatory requirements, indicating the safety of production and the feasibility of applying this technology in industrial settings.

Dioscorea bulbifera is commonly known as air potato present in the tropical and subtropical regions. It is a perennial climber traditionally used for various therapeutic purposes by traditional healers. This review explores various medicinal uses of D. bulbifera and its active ingredients, as well as describes its nanoparticle synthesis for medical applications. The Google Scholar search engine was used to conduct this comprehensive review along with the databases of the following publishers: Elsevier, Springer, Taylor and Francis, Bentham, and PubMed. D. bulbifera contains several bioactive compounds that are responsible for its pharmacological properties, such as antioxidant, anti-inflammatory, neuroprotective, anticancer, and antidiabetic properties. It is also used as a nutritive functional food. D. bulbifera-mediated nanoparticle synthesis has been established by the scientific communities for various medicinal applications. D. bulbifera contains numerous active ingredients, including diosbulbins, bafoudiosbulbin, β-sitosterol, diosgenin, dioscin, pennogenin, myricetin, quercetin, and stigmasterols with numerous biological activities. In addition, it has a vital role in synthesizing nanoparticles with good pharmacological applications, especially in drug delivery systems. However, its potential characteristic features and functional properties of the active molecules present in this tuber need to be further explored in clinical trials. We suggest that using this edible tuber, we may formulate the valueadded food with good medicinal applications.

Effects of chickpea grain feeding on the growth and carcass features of growing lambs.

An investigation was conducted to find out how diet formulation of chickpea grains (CHPE) rather than soybean meal and barely grain affected the performance, blood metabolites, carcass, and meat quality features of Awassi lambs. Thirty lambs, with an average age of 73 ± 0.85 days and an initial body weight of 21.0 ± 1.29kg, were randomly assigned into one of three diets, with 10 lambs per treatment diet. The diets were designed to replace a portion of the barley grain and soybean meal and included no CHPE (CON), 7.5% CHPE (CHPE7.5), and 15% CHPE (CHPE15). Lambs were individually housed, fed every day, and weighed every two weeks to measure performance characteristics over the 60-day study period. Four lambs per treatment were chosen at random on day 42 to participate in an N balance study and assess diet digestibility. All lambs were slaughtered at the termination of the trial period to measure the features of the carcass characteristics and meat quality. As the amount of CHPE included in the diets increased, the cost of diets reduced. As the amount of CHPE in the diets increased, so did the intake of ether extract (EE). The CON group's cost per kilogram of increase was higher (P = 0.017) than that of the CHPE7.5 and CHEP15 groups. The digestibility of EE was higher (P = 0.024) in the CHPE15 diet as opposed to the CHPE7.5 and CON diets. The various treatments did not impact blood metabolites, carcass features, or meat quality. Therefore, the present study suggested that chickpeas might be added to the diets of finishing lambs up to 15% of dry matter.

Morphofunctional indicators of the body students of the medical university

Introduction. The period of adolescence accounts for the completion of the growth processes of the body, and the beginning of stabilization of functional indicators, which, as more plastic factors, are more sensitive to environmental conditions. Measuring, evaluating, and predicting morphofunctional parameters of the body of medical university students, taking into account regional standards of physical development, is one of the priorities of modern medicine and scientific research in general.The aim of the study is to study the features of anthropometric and functional characteristics, vegetotype of medical university students in comparison with the current regional standard.Materials and methods. Anthropometric and functional parameters were measured in 300 medical students (77 males, 223 females), aged 19,1±0,88 years.Results. It is shown that anthropometric characteristics of students significantly exceed the regional standard, in boys it is body length (p&lt;0,01), and weight-height ratio (p&lt;0,05), in girls it is body length, chest circumference and weight-height ratio (p&lt;0,01). Cardiointervalography parameters revealed 4,01 % vagotonics, 88,33 % eutonics and 7,62 % sympathotonics, a significant difference (p&lt;0,01) was also found in linear cardiointervalogram parameters in cohorts of these vegetotypes. Functional indices in absolute terms revealed compliance with the regional standard only in vital capacity of lungs, carpal dynamometry is significantly lower than the standard, in girls (p&lt;0,01), boys (p&lt;0,05), haemodynamics in terms of diastolic blood pressure and heart rate significantly (p&lt;0,01) exceeds the reference values. Integral functional indices: vital index, vegetative index, minute volume of respiration differ significantly by sex (p&lt;0,05); Kerdo index, minute volume of blood circulation showed a significant difference by vegetotype (p&lt;0,05); pulse pressure showed a significant difference by sex and vegetotype (p&lt;0,01).Conclusion. The studies showed statistically significant excesses relative to the regional standard in young men in body length (p&lt;0,01) and mass-height ratio (p&lt;0,05), in chest circumference in girls (p&lt;0,01); in diastolic blood pressure and heart rate in boys and girls (p&lt;0,01). Absolute and integral indices of cardio-respiratory system are significantly higher in sympathotonics than in vagotonics. Young men, relative to girls, demonstrate higher absolute, linear values of cardiointervalogram (p&lt;0,01), in the whole population these indices are within the range of norm of the regional standard. Among students the majority 88,33 % have normotonic type of ANS. The obtained results, in our opinion, show the need for systematic monitoring of objective morphofunctional state of modern youth.

GIRLISH SONGS OF THE YOUTH OF THE INHABITANTS OF THE TIMES OF 1900 - 1927 OF THE DARAVATSKY VILLAGE COUNCIL OF KOZHUKHOV VOLOST IN THE PRACTICE OF COMMUNICATIVE AND SPEECH PORTRAITURE THE LINGUISTIC PERSONALITY OF A NATIVE OF THE NORTHERN VILLAGE

The article implements the problems of dialect linguistic personology, it solves the problem of communicative and speech portrayal of the linguistic personality of Vasily Ardalyonovich Morozov (1904-1980) on the basis of a linguistic analysis of his handwritten archive and memories of his children and grandchildren. Considerable attention is paid in this article to the handwritten list of Vologda ditties - one of the significant components of the studied manuscript archive, which is important both for studying the traditional spiritual culture of the Russian North and for describing the cultural life of the Morozov family in rural and urban everyday life. Based on the study of the handwritten list of ditties, the phonetic, lexical and grammatical features of dialect origin characteristic of the author of the manuscript, reflected in written speech, characterizing V.A. Morozov as a native speaker of the northeastern (Vologda) dialects of the northern dialect of the Russian language, are revealed. The list of folk songs represents the distinctive features of the author's graphics and spelling, on the one hand, showing the utmost accuracy in presenting the factual component of the manuscript, and on the other, allowing numerous spelling and punctuation errors, the presence of which reveals a clear lack of education of the informant. The article also comments on the motifs and images of folk ditties closest to V.A. Morozov. This is the motif of playing the accordion, mentioning the attributes of military service, as well as items of men's clothing fashionable in the first quarter of the twentieth century. The identification of motives and images important to the informant became possible by comparing the texts written by his hand with the recordings of texts of this folklore genre performed by his wife A.N. Morozova.

Features of spectral characteristics of phenyl-containing vanadium (III) β-diketonates

Tris-dibenzoylmethanate ([V(dbm)3 ]) and tris-benzoylacetonate vanadium ([V(bac)3 ]) were obtained by electrochemical synthesis. The composition of chelates was determined using elemental analysis and IR spectral data. It was shown that the formation of a quasi-aromatic metallocycle, the main structural element of chelate, occurred as a result of electrolysis. At the same time, the batachromic shift of absorption bands of carbonyl groups was more than 100 cm–1. The overwhelming majority of absorption bands in the IR spectra of both compounds had mixed nature. For ([V(dbm)3 ] the characteristic of absorption bands did not exceed 13.5 %, and for [V(bac)3 ] – 10.3 %. The peripheral groups of ligands (phenyl and methyl) did not undergo transformation when influenced by electric current.
