Authors: Kausthubha Prabhu , Kannan N.
Published: May 2024

Exopolysaccharides (EPS) are bio-molecules produced by variety of microorganisms by both eukaryotes and prokaryotic. EPS are high molecular weight molecules available in both homopolysaccharide and heteropolysaccharide. Plants are the primary source of exopolysaccharides (EPS); however, microbiological EPS have a diverse range of structures and functions that enable them to endure harsh environmental conditions. Studying the structure and composition of exopolysaccharides is crucial for understanding their beneficial functions and potential applications in different fields such as food, dairy, medical, pharmaceutical, cosmetics and other industries. This review briefly describes how extremities trigger microbes to produce EPS with unique properties. In addition, it covers optimization and strain improvement methods to increase the productivity of microbes, extraction and purification methods. Similarities and differences of solid-state fermentation and submerged fermentation for EPS production from Bacteria and Fungi are sighted in this review. Applications of EPS in different fields owing to their various physicochemical properties are also discussed in this review. This review provides explanations with respect to microbial habitats, fermentation scales, purification methods and recent research on their potential applications.
Characterisation and toxins analysis of symbiotic bacteria Photorhabdus luminescens isolated from Heterorhabditis indica ICRI-18 strain
Authors: Augustine Joel , Muthuprakash Siva K.M. , Abraham Jayanthi
Published: May 2024

Entomopathogenic nematodes are proven alternatives to pesticides in crop protection as they belong to the Heterorhabditidae and Steinernematidae families. The role of entomopathogenic nematodes has expanded considerably in the recent past for their efficacy as biopesticide which is influenced by nematode species and strain. Members of the genus Heterorhabditis have been found to harbor a symbiotic bacteria Photorhabdus sp. When the nematode is ingested by the insect, Photorhabdus sp. is released into the host haemocoel where they multiply rapidly and kill the insect. The main objective of our research was to examine the insect killing toxin property of symbiotic bacteria isolated from the entomopathogenic nematodes Heterorhabditis indica. The antagonistic potential of insecticidal toxin from Photorhabdus sp. was investigated. The results prove that toxic components produced by these bacteria could kill pests either through ingestion or injection. The broad-spectrum antimicrobial property produced by Photorhabdus sp. was analysed by conducting both antibiogram and antibiosis studies.
Isolation and screening of microplastics from Nodularia spumigena and Phaeodactylum tricornutum and determining the efficacy of biodegradation of microplastics obtained using the synergistic consortium
Authors: Kushbu R. , Malleshappa Madhu
Published: May 2024

Microplastics are a form of plastics which are less than 5mm in size. They are the major threat for the environment and mankind, as they critically influence the food chain. The best way to extinct them from the environment is to degrade them in eco-friendly manner where biodegradation is the optimal therapy. Phytoplanktons play a vital role in phytoremediation. They are capable of in taking certain water pollutants such as micro plastics. Nodularia spumigena and Phaeodactylum tricornutum were screened and the microplastics were extracted using optimized enzymatic or alklanized digestion process and then dried. The micro plastics obtained were weighed and the concentration of microplastic present per gram of the sample was calculated. UV- VIS spectroscopy and FTIR instrumental analysis were used to analyse the digestion process. In order to formulate a synergistic consortium to degrade the thus obtained microplastic, plastic undergoing the natural degradation process from the dump yard was collected and crowded plate technique was performed and the strains involved in the degradation were thus isolated and identified and sequenced. Synergistic consortium was formulated and then incubated with the microplastics screened. The incubation period was of about 60 days. UV- Spectroscopic analysis was done on 0th day, 30th day and 60th day. The graph evidently illustrates the difference as the incubation time progresses. The peak depicts the microplastic degradation based on the turbidity. As the microplastic gets degraded, the growth of the organism in the consortium also gets limited because the microplastics are the only source of carbon.

Authors: Ootahara Takuto , Hatakeyama-Sato Kan , Thomas Morgan L. , Takeoka Yuko , Rikukawa Masahiro , Yoshizawa-Fujita Masahiro
Published: May 2024

Ionic plastic crystals (IPCs), which are soft crystals with plasticity and ionic conductivity, are expected to be applied as solid electrolytes in battery applications. Further improvement of ionic conductivity is necessary for practical use as an electrolyte for energy storage devices. Materials Informatics (MI) is a method of incorporating information science in materials development. In this research, MI is being used to develop IPCs with high ionic conductivity. By using informatics science in addition to chemical knowledge, this research can be carried out efficiently and innovatively. The synthesis of eight new compounds resulted in six of them being solid at room temperature, while two of them were in a liquid state, namely ionic liquids. We evaluated the phase transition temperatures and ionic conductivity for each compound. Notably, N-ethyl-N-methylpyrrolidinium trifluoromethyltrifluoroborate ([C2mpyr][CF3BF3]) exhibited a high ionic conductivity of 1.75×10-4 S cm-1 at 25 oC, which is one of the highest values reported among IPCs to date. The combination of an experimental and MI based approach revealed an improved understanding of the relationship between ion size and ionic conductivity for a series of pyrrolidinium-based IPCs, and it is expected that further improvements to this approach will yield greater understanding of structure-property relationships.
Assessing the domain-based local pair natural orbital (DLPNO) approximation for non-covalent interactions in sizable supramolecular complexes
Authors: Gray Montgomery , Herbert John
Published: May 2024

The titular DLPNO approximation {\red is the most widely used method} for extending correlated wave function models to large molecular systems, yet its fidelity for intermolecular interaction energies has not been thoroughly vetted. Non-covalent interactions are sensitive to tails of the electron density, involving parts of the wave function that are far from the nuclei and may be discarded in some local correlation treatments. Meanwhile, the accuracy of the DLPNO approximation is known to deteriorate as molecular size increases, and questions have been raised regarding the accuracy of benchmark calculations for large van der Waals complexes. We test the DLPNO approximation at the level of second-order Moller-Plesset perturbation theory (MP2) in systems containing as many as 240 atoms, for which canonical MP2 calculations can be performed for comparison. For small dimers with <~ 10 heavy atoms, DLPNO-MP2 interaction energies are within 3% of canonical values. However, the approximation is quite poor for larger systems unless the results are extrapolated to the limit where the threshold for discarding PNOs is taken to zero. For a sequence of nanoscale graphene dimers up to (C96H24)2, extrapolated DLPNO-MP2 interaction energies agree with canonical values to within 1%, independent of system size, provided that the basis set does not contain diffuse functions. The presence of diffuse basis functions causes oscillatory behavior as a function of the PNO threshold, making it impossible to extrapolate the results in a meaningful way. The significance of these results for higher-level coupled-cluster benchmarks is also addressed, via calculations in small dimers.
Roadmap for the development of transition metal oxide cathodes for rechargeable zinc-ion batteries
Authors: Miliante Caio , Gourley Storm , Adams Brian , Higgins Drew , Rubel Oleg
Published: May 2024

Rechargeable zinc-ion batteries (RZIBs) are a promising multivalent battery technology for grid-scale energy storage applications, thanks to their abundant materials, lower environmental impact, and higher safety due to the use of aqueous electrolytes as compared to lithium-based batteries. However, there is still a lack of cathode materials with suitable stability and performance for reliable implementation in these energy storage applications. In this study, we have utilized readily available thermodynamic properties obtained from first-principle atomistic simulations to calculate the intercalation potential of zinc in numerous potential candidate cathode materials. We confined our chemical space to simple transition metal oxides (MxOy, where M is a transition metal). While some materials in this class were previously experimentally studied (e.g., MnO2, V2O5, MoO3), a literature survey revealed multiple oxides for which no prior investigation on their use as cathodes for RZIBs had been performed. We considered previously reported structures with similar atomic arrangements for the charged and discharged phases, the feasibility of experimental realization of the materials, the electrochemical stability of the charged cathode in an aqueous environment, and the potential degradation of aqueous electrolytes in our analysis. We mapped the zinc intercalation potential for over 50 redox pairs involving oxides of 12 different elements. These calculated theoretical potentials were then compared to previously obtained experimental results, with the relatively small difference between them (approximately 0.2 V) demonstrating the predictive capabilities of the utilized methodology. Previously overlooked materials with high intercalation potential (above 1.6 V vs Zn/Zn2+) were then proposed as cathode materials for RZIBs. The Zn2+ intercalation potential mapping for the oxide redox pairs achieved in this study provides a roadmap for future experimental investigations of novel cathode materials for RZIBs.
Global Aromaticity in Neutral Porphyrin Nanobelts
Authors: Vitek Marco , Deng Jie-Ren , Anderson Harry L. , Rončević Igor
Published: May 2024

The ability of a ring-shaped molecule to sustain a global ring current, when placed in a magnetic field, indicates that its electronic wavefunction is coherently delocalized around its whole circumference. Large molecules that display global ring currents are attractive components for molecular electronic devices because it should be possible to control charge transport through these molecules using quantum interference. Here, we use theoretical methods to investigate how the global ring currents in molecular nanobelts built from edge-fused porphyrins evolve with increasing ring size. Our predictions were validated by using coupled clusters to construct a density functional approximation (denoted OX-B3LYP) that is specifically tailored to accurately describe these nanobelts. The results indicate that a global ring current persists in neutral belts consisting of up to about 22 porphyrin units, with Hückel circuits of 220 electrons (circumference 18.6 nm), which is surprising because global ring currents have not previously been reported in neutral macrocycles of this size.
pKa Prediction in Non-Aqueous Solvents
Authors: Zheng Jonathan W. , Al Ibrahim Emad , Green William H.
Published: May 2024

Acid dissociation constants (pKa) are widely measured and studied, most typically in water. Comparatively few datasets and models for non-aqueous pKa values exist. In this work, we demonstrate how the pKa in one solvent can be accurately determined using reference data in another solvent, corrected by solvation energy calculations from the COSMO-RS method. We benchmark this approach in ten different solvents, and find that pKa values calculated in six solvents deviate from experimental data on average by less than 1 pH unit. We observe comparable performance on a more diverse test set including amino acids and drug molecules, with higher error for large molecules. The model performance in four other solvents is worse, with some MAEs exceeding 3 pH units; we discuss how such errors arise due to both model error and inconsistency in data calibration. Finally, we demonstrate how this technique can be used to estimate the proton transfer energy between different solvents, and use this to report a value of the proton’s solvation energy in formamide, a quantity that has does not have a consensus value in literature.

Published: May 2024

Native mass spectrometry (nMS) is increasingly popular for studying intact protein quaternary structure. When coupled with ion mobility, which separates ions based on their size, charge, and shape, it provides additional structural information on the protein complex of interest. In this study, we present a novel prototype TIMS (trapped ion mobility spectrometry)-Quadrupole-SID (surface-induced dissociation)-Time of Flight, TIMS-Q-SID-TOF, instrument for nMS. The modifications include changing the TIMS cartridge from concave to convex geometry electrodes and operating TIMS at 425 kHz to improve the trapping efficiency for high mass-to-charge (m/z) ion mobility analysis, such as 3 and 4 MDa hepatitis B virus capsids. The quadrupole radiofrequency driver was lowered to 385 kHz, which extends the isolation range from 3,000 to 17,000 m/z and allows isolation of a single charge state of GroEL at 16,200 m/z with an isolation window of 25 m/z. Finally, a 6-mm thick, 2-lens SID device replaced the collision cell entrance lens. SID dissociated 801 kDa GroEL into all combinations of subcomplexes, and the peaks were well-resolved allowing for confident assignment of product ions. This is the first time a novel prototype timsTOF Pro for nMS has been introduced with high resolving power ion mobility separation coupled to high m/z quadrupole selection and SID for protein complex fragmentation with product ion collection and detection across a broad m/z range of 1,500 to 40,000.
Chemography-guided analysis of a reaction path network for ethylene hydrogenation with a model Wilkinson’s catalyst
Authors: Gantzer Philippe , Staub Ruben , Harabuchi Yu , Maeda Satoshi , Varnek Alexandre
Published: May 2024

Visualization and analysis of large chemical reaction networks become rather challenging when conventional graph-based approaches are used. As an alternative, we propose to use the chemical cartography (“chemography”) approach, describing the data distribution on a 2-dimensional map. Here, the Generative Topographic Mapping (GTM) algorithm – an advanced chemography approach – has been applied to visualize the reaction path network of a simplified Wilkinson’s catalyst-catalyzed hydrogenation containing some 105 structures generated with the help of the Artificial Force Induced Reaction (AFIR) method using either Density Functional Theory or Neural Network Potential (NNP) for potential energy surface calculations. Using new atoms permutation invariant 3D descriptors for structure encoding, we’ve demonstrated that GTM possesses the abilities to cluster structures that share the same 2D representation, to visualize potential energy surface, to provide an insight on the reaction path exploration as a function of time and to compare reaction path networks obtained with different methods of energy assessment.

Burn out, coaching philosophy, and why the end does not justify unethical means – here’s why sport coaches should follow a deontological ethical approach
Authors: Huddleston Alex , Crisp Philippe , Bright Dave
Published: May 2024

The cultural importance of sport across the world is well established, with meaningful significance given to policies that promote participation for health and psychosocial reasons, strong narratives, nation-building, and entertainment formed through the consumption, both contemporary and historical, of performance sport. In this commentary, we argue and provide evidence that any examination of sports culture inevitably ties to ideologies of performance, and that oftentimes this results in approaches to the development of athletes and sportspeople that overemphasize profoundly unethical means of achieving a variety of performance ends. Because of this, our position in this commentary uses a philosophical perspective to justify our proposition, one that espouses a more holistic approach for sport coaches, organizers, and architects that, through supporting athletes and focusing on development, actually mirrors scientific principles for sport performance, more so, we believe, than any ‘win at all costs’ approach.

Published: May 2024

Objective: To explore the application effect of oral care combined with psychological intervention on improving patients’ oral hygiene and alleviating negative emotions. Methods: A total of 78 patients admitted to the hospital between January and December 2023 were recruited and divided into two groups using a random number table method, each group consists of 39 cases. The control group received routine care, while the study group received oral care combined with psychological intervention. Oral health scores and the patients’ negative emotional states were compared between the two groups. Results: The oral health score of the study group (35.66 ± 5.69) was significantly better than that of the control group (26.36 ± 6.21; P < 0.05). Additionally, the depressed mood and anxiety scores of the study group (27.69 ± 6.12 and 26.36 ± 6.21, respectively) were significantly lower than those of the control group (36.23 ± 5.98 and 35.66 ± 5.69, respectively; P < 0.05). Conclusion: Clinical research combining routine care, psychological intervention, and oral care has revealed that the combined approach significantly enhances patients’ treatment adherence, alleviates negative emotions, and improves their quality of life.
Emotions in economic activity: a case study of Polish entrepreneurs in the SME sector
Authors:   Jan Kochanowski University in Kielce, Faculty of Law and Social Sciences, Department of Economics and Finance, Banaszek Marcin
Published: May 2024

Purpose: The aim of this article is to comprehend the role of emotions in the business decision making process and to identify the influence of emotions on the economic behaviors of entrepreneurs, considering their satisfaction levels and ability to manage emotions in the workplace. Design/methodology/approach: The theoretical part of the study draws on a critical literature review, whereas the empirical one employs a diagnostic survey based on a questionnaire as a research tool. To analyse the data, descriptive statistics were obtained and a correlation study was performed. Findings: The study revealed that most of the entrepreneurs surveyed are satisfied with the conduct of business activities and that satisfaction is related to various economic behaviours. Entrepreneurs experience both positive (satisfaction, enthusiasm) and negative (anxiety, embarrassment) emotions. Positive emotions correlate with positive economic behaviors, while negative emotions have the opposite effect. Most entrepreneurs assess their emotional management abilities at least at an average level, but there are areas for improvement. There are differences in self-assessment of emotional control abilities before making business decisions among entrepreneurs. The presented conclusions suggest the necessity for ongoing enhancement of emotional competencies to bolster the positive development of enterprises. Research limitations/implications: Study limitations include the absence of longitudinal analysis, hindering the assessment of satisfaction and economic behavior dynamics. Future research should consider exploring external factors' impact on the relationship between satisfaction and economic behaviors, providing a more comprehensive analysis of contextual influences on entrepreneurs' decisions. Practical implications: Research results reveal significant connections between entrepreneurs' satisfaction and economic behaviors, emphasizing the role of emotions in business decisions. Practical implications recommend conscious emotion management, achieving work-life balance, and diversifying support. Entrepreneurs can benefit from implementing emotion management strategies, which can improve business efficiency, encourage innovation, and improve the handling of business challenges. Originality/value: This article introduces a holistic perspective on the interplay between entrepreneurs' satisfaction and economic behaviours, emphasising emotions' role in decision making. Its value lies in combining research on satisfaction, emotions, and their management, offering practical recommendations for both business practitioners and researchers interested in the psychological aspects of corporate functioning. Keywords: Emotions in business, economic behaviors, emotional management, behavioral finance. Category of the paper: Research paper.

Published: May 2024

Purpose: The aim of the article is to examine the reasons why organizations do not use the information obtained in the audit process. Design/methodology/approach: For the realization of the work we used the results of our own research of organizations that have certified quality management systems for compliance with the requirements of ISO 9001. The information obtained relates to organizations operating in the territory of Poland. Findings: Organizations conducting quality management system audits acquire a variety of information that should be used for management purposes. Some organizations have serious problems with acquiring data and processing it, and using the information for decision-making and improvement-oriented activities. The paper identifies 10 potential reasons why organizations do not use information from the audit process. A comparison was made between the causes found in internal and external audits. An analysis of each of the identified causes was carried out, paying attention to their origins. Attention was paid to the connections between the causes. Directions for eliminating problems were indicated. Practical implications: The results obtained have practical application. Organizations with an awareness of the causes of problems are able to take, both corrective action and preventive action. In the first case, it is about taking corrective actions to existing problems. In the second case, it is about preventive actions, which should prevent a problem from arising. Social implications: The results obtained have social implications. They draw attention to the need to build a pro-quality and improvement-oriented awareness. Originality/value: The article for the first time identifies the causes of problems arising in organizations in the context of the use of audit information. Attention is paid to the mechanism of disorders and ways to eliminate them are indicated. The article is especially recommended to the top management of organizations that conduct system audits. Keywords: audit, information management, quality management system, improvement. Category of the paper: viewpoint.

Published: May 2024

Purpose: This study aimed to characterise the nutritional behaviour of Gdynia Maritime University students in terms of consuming various types of drinks as a water source. Moreover, the aim was to analyse the determinants of these behaviours in the context of selected socioeconomic parameters that differentiate the studied group of respondents. Design/methodology/approach: The tool used to conduct the study was a survey questionnaire. The questions concerned the nutritional behaviour of students regarding the consumption of beverages as a source of water and the conditions for their diversity. Findings: The main source of water for students was mineral water. Unfortunately, it is associated with environmental pollution related to the packaging of this water (PET bottle). The second important source of water was tap water. This should be considered a manifestation of a developing trend in health-promoting, ecological and economic behaviours among the students. None of the socioeconomic factors differentiated students' behaviours when choosing bottled water. Research limitations/implications: Students constitute a specific group of respondents. It should be expected that their current behaviours will reflect the behaviour of a wider society group, but only in the future. Therefore, the results obtained in this study can be considered limited, especially in the short term. Thus, this study should be conducted in a group of older respondents. Then, the following study should be repeated on older respondents in the distant future. On this basis, it is possible to verify how the change behaviours of respondents over time. The obtained results should allow us to verify the assumption that students' behaviours can be treated as indicators of the behaviours of the future society. Practical implications: Consumers' eating behaviour regarding water consumption has health and environmental consequences. This approach to analysing water consumption is strategic because it concerns the direct and indirect impact on human health and quality of life. Originality/value: The study results were used to formulate conclusions regarding behaviours that determine human health, the state of the environment and, consequently, quality of life. Keywords: eating behaviour, bottled water, tap water, determinants of water choice, impact on the environment, freshwater deficit. Category of the paper: Research paper

Purpose: Contacts with foreigners and their somewhat different ways of thinking and behavior (often incomprehensible to the Polish society), reaching back to the roots of the culture of a given country, region or community, are becoming an everyday reality nowadays. These processes also affect the change of standards in the field of intercultural competencies of managerial staff. The aim of this paper is to discuss the development of cultural competencies in managers that are necessary in the management of intercultural organizations. Design/methodology/approach: The paper uses the desk research method of analysis. The analysis of available subject literature and data obtained from the websites of six Polish agricultural universities enabled establishment of facts, verification of data and presentation of results. Findings: The considerations presented in the article indicate that the key element of the changes taking place in organizations are intelligent human resources with cultural competencies. International cooperation and foreign contacts are important – whether through participation in common projects, conferences, research or student internships. Joint actions are also required rather than individual actions and the initiatives undertaken are consistent with the concept of the society 5.0. Practical implications: A common space for development, modern technology, creative thinking and joint commitment of the managerial staff and the academic community enable the building of a super-intelligent society and universities fit for the 21st century. Social implications: The advances in technology should always be used with consideration of the needs and the good of people, regardless of cultural differences. The world of people, machines and their surroundings should be interconnected and all these elements should be able to communicate with each other. Originality/value: The article is an original approach to searching for solutions that influence the change of standards in the area of key competencies of managerial staff, including intercultural competencies. Keywords: cultural competencies, intercultural manager, changes in organizations. Category of the paper: research paper.
