Charge and spin transfer dynamics in a weakly coupled porphyrin dimer
Authors: Kopp Sebastian , Redman Ashley , Roncevic Igor , Schröder Lisa , Bogani Lapo , Anderson Harry , Timmel Christiane
Published: April 2024

The dynamics of electron and spin transfer in the radical cation and photogenerated triplet states of a tetramethylbiphenyl-linked zinc-porphyrin dimer were investigated, so as to test the relevant parameters for the design of a single-molecule spin valve, and the creation of a novel platforms for the photogeneration of high-multiplicity spin states. We used a combination of multiple techniques, including variable-temperature continuous wave EPR, pulsed proton electron–nuclear double resonance (ENDOR), transient EPR, and optical spectroscopy. The conclusions are further supported by density functional theory (DFT) calculations, and comparison to reference compounds. The low-temperature cw-EPR and room-temperature near-IR spectra of the dimer monocation demonstrate that the radical cation is spatially localized on one side of the dimer at any point in time, while the EPR spectra at 298 K reveal rapid hopping of the radical spin density between both sites of the dimer via reversible intramolecular electron transfer. The hyperfine interactions are modulated by electron transfers and can be quantified using ENDOR spectroscopy. This allowed simulation of the variable- temperature cw-EPR spectra with a two-site exchange model and provided information on the temperature-dependence of the electron transfer rate. The electron-transfer rates range from about 10.0 MHz at 200 K to about 53.9 MHz at 298 K. The activation enthalpies ∆‡H of the electron transfer were determined as ∆‡H = 9.55 kJ mol−1 and ∆‡H = 5.67 kJ mol−1 in a 1:1:1 solvent mixture of CD2Cl2:toluene-d8:THF-d8 and in 2-methyltetrahydrofuran, respectively, consistent with a Robin–Day class II mixed-valence compound. Investigation of the spin-density distribution of the photogenerated triplet state of the Zn-porphyrin dimer reveals localization of the triplet-spin density on a nanosecond time scale on one half of the dimer at 20 K in 2-methyltetrahydrofuran and at 250 K in a polyvinylcarbazole film. We highlight how these results impact the design of single-molecule spintronic devices, quantifying fundamental parameters for relevant building blocks, and offer the first step towards a novel platforms for photogenerated high-multiplicity spin states.
Deciphering Spin-Activity Relationships of FeN4 Moieties Bridged in Halogenated MXenes for Oxy-gen Reduction
Authors: Zhang Shuren , Sun Genban
Published: April 2024

pin control of the FeN4 moieties is critical for enhancing the electrocatalytic oxygen reduction reaction (ORR). The relationship between the spin state transitions of the FeN4 moieties and ORR activity is complex and remains debatable due to the discrepancies between the theoretical models and experi-mental catalyst structures, along with potential misinterpreting the characterization data. In this study, we utilized Ti3C2Tx MXenes with various terminations (−I, −Br, −Cl, −F, and −O) integrated with iron phthalocyanine (FePc) to form model catalysts with defined FeN4-Tx-Ti structures; this enabled the pre-cise modulation of the FeN4 spin states, established a clear correlation between the intermediate spin states, and improved the ORR performance. Specifically, compared FePc with a 17.1% intermediate spin state, Ti3C2Brx/FePc with an 88.1% intermediate spin state exhibited superior electrochemical per-formance, showing an ORR half-wave potential of 0.94 V versus RHE and doubled power densities in Zn-air batteries (252.5 mW cm-2) and H2-O2 fuel cells (350.7 mW cm-2). Theoretical studies confirmed that the intermediate spin state led to electron filling in the antibonding orbital composed of the Fe 3dz2 and O2 π* orbitals, significantly improving the O2 activation and ORR activity. This research advances our understanding of the spin-related origins of catalytic activity and facilitates the design and optimiza-tion of advanced ORR catalysts.

Authors: Rojas-Luna Raul , J. Romero-Salguero Francisco , Esquivel Dolores , Roy Souvik
Published: April 2024

The catalytic activity towards CO2 photoreduction, including reaction rate, product selectivity, and longevity, is highly sensitive to the coordination structure of the catalytic active sites, and the precise design of the active site remains a challenge in heterogeneous catalysts. Herein, we report modulation of the coordination structure of MNx-type active sites (M = Co or Ni; x = 4 or 5) anchored on a periodic mesoporous organosilica (PMO) support to improve photocatalytic CO2 reduction. The PMO was functionalised with pendant 3,6-di(2′-pyridyl)pyridazine (dppz) groups to allow immobilisation of molecular Co and Ni complexes with polypyridine ligands. A comparative analysis of CO2 photoreduction in the presence of an organic photosensitizer (4CzIPN, 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) and a conventional [Ru(bpy)3]Cl2 sensitiser revealed strong influence of the coordination environment on the catalytic performance. CoN5-PMO demonstrated a superior CO2 photoreduction activity than the other materials and displayed a cobalt-based turnover number (TONCO) of 92 for CO evolution at ~75% selectivity after 3 h irradiation in the presence of 4CzIPN. The hybrid CoN5-PMO catalyst exhibited better activity than its homogeneous [CoN5] counterpart, indicating that the heterogenisation promotes the formation of isolated active sites with improved longevity and faster catalytic rate.

Published: April 2024

In this work, we build a computationally inexpensive, data-driven model that utilizes only atomistic structure information to predict the reactivity of interfaces between any candidate solid-state electrolyte material and a Li metal anode. This model is trained on data from ab initio molecular dynamics (AIMD) simulations of the time evolution of the solid electrolyte-Li metal interface for 67 different materials. Predicting the reactivity of solid state interfaces with ab initio techniques remains an elusive challenge in materials discovery and informatics, and previous work on predicting interfacial compatibility of solid-state Li-ion electrolytes and Li metal anodes has focused mainly on thermodynamic convex hull calculations. Our framework involves training machine learning models on AIMD data, thereby capturing information on both kinetics and thermodynamics, and then leveraging these models to predict the reactivity of thousands of new candidates in the span of seconds, avoiding the need for additional weeks-long AIMD simulations. We identify over 300 new chemically stable and over 780 passivating solid-electrolytes that are predicted to be thermodynamically unfavored. Our results indicate many potential solid-state electrolyte candidates have been incorrectly labeled unstable via purely thermodynamic approaches using density functional theory (DFT) energetics, and that the pool of promising, Li-stable solid-state electrolyte materials may be much larger than previously thought from screening efforts. To showcase the value of our approach, we highlight two borate materials that were identified by our model and confirmed by further AIMD calculations to likely be highly conductive and chemically stable with Li: LiB13C2 and LiB12PC.
Effects of Substituted Triarylphosphine Ligands on Electron Transfer in [(p-cymene)Ru] Complexes
Authors: Micci Anthony , Lionetti Davide
Published: April 2024

The consequences of electron transfer in ruthenium-arene catalysts supported by triarylphosphine ligands has not been fully elucidated in coordinating solvents, which are known to engender further transformations in analogous Ru species upon oxidation and may reveal new modes of reactivity in these compounds. Herein, we report the electrochemical characteriza-tion of (p-cymene)RuCl2(PArX3) complexes containing substituted triarylphosphine ligands (PArX3) and investigate the ef-fects of the ligand substituents on ET processes. These complexes undergo ET at potentials that depend on the phosphine ligand substituents (X); in coordinating solvents, electrochemically-generated Ru(III) species are converted into new prod-ucts whose formation and ET behavior also show dependence on the nature of these substituents. Based on literature prece-dent and on evidence for loss of cymene in these transformations, the products of these reactions are formulated as the tris(nitrile) complexes (PArX3)RuCl2(NCCH3)3.

Published: April 2024

Background: Persistent, Mobile and Toxic (PMT), or very Persistent and very Mobile (vPvM) substances are a wide class of chemicals that are recalcitrant to degradation, easily transported, and potentially harmful to humans and the environment. Due to their persistence and mobility, these substances are often widespread in the environment once emitted, particularly in water resources, causing increased challenges during water treatment processes. Some PMT/vPvM substances such as GenX and perfluorobutane sulfonic acid have been identified as substances of very high concern (SVHCs) under the European Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation. With hundreds to thousands of potential PMT/vPvM substances yet to be assessed and managed, effective and efficient approaches that avoid a case-by-case assessment and prevent regrettable substitution are necessary to achieve the European Union's zero-pollution goal for a non-toxic environment by 2050. Main: Substance grouping has helped global regulation of some highly hazardous chemicals, e.g., through the Montreal Protocol and the Stockholm Convention. This article explores the potential of grouping strategies for identifying, assessing and managing PMT/vPvM substances. The aim is to facilitate early identification of lesser-known or new substances that potentially meet PMT/vPvM criteria, prompt additional testing, avoid regrettable use or substitution, and integrate into existing risk management strategies. Thus, this article provides an overview of PMT/vPvM substances and reviews the definition of PMT/vPvM criteria and various lists of PMT/vPvM substances available. It covers the current definition of groups, compares the use of substance grouping for hazard assessment and regulation, and discusses the advantages and disadvantages of grouping substances for regulation. The article then explores strategies for grouping PMT/vPvM substances, including read-across, structural similarity and commonly retained moieties, as well as the potential application of these strategies using cheminformatics to predict P, M and T properties for selected examples. Conclusion: Effective substance grouping can accelerate the assessment and management of PMT/vPvM substances, especially for substances that lack information. Advances to read-across methods and cheminformatics tools are needed to support efficient and effective chemical management, preventing broad entry of hazardous chemicals into the global market and favouring safer and more sustainable alternatives.
Energetic landscape and terminal emitters of phycobilisome cores from quantum chemical modeling
Authors: Cupellini Lorenzo , Gwizdala Michal , Kruger Tjaart
Published: April 2024

Phycobilisomes (PBs) are giant antenna supercomplexes of cyanobacteria that use phycobilin pigments to capture sunlight and transfer the collected energy to membrane-bound photosystems. In the PB core, phycobilins are bound to particular allophycocyanin (APC) proteins. Some phycobilins are thought to be terminal emitters (TEs) with red-shifted fluorescence. However, the precise identification of TEs is still under debate. In this work, we employ multiscale quantum-mechanical calculations to disentangle the excitation energy landscape of PB cores. Using the recent atomistic PB structures from Synechoccoccus PCC 7002 and Synechocystis PCC 6803, we compute the spectral properties of different APC trimers and assign the low-energy pigments. We show that the excitation energy of APC phycobilins is determined by geometric and electrostatic factors, and is tuned by the specific protein-protein interactions within the core. Our findings challenge the simple picture of a few red-shifted bilins in the PB core and instead suggest that the red-shifts are established by the entire TE-containing APC trimers. Our work provides a theoretical microscopic basis for the interpretation of energy migration and time-resolved spectroscopy in phycobilisomes.

Published: April 2024

Clickbait is a sensationalized headline prevalent online, aiming to entice people to click a link, an advertisement, or a headline. The study intends to find out how such a phenomenon is perceived by consumers and the extent of its influence on purchasing decisions through the combined approaches of structured survey questionnaires containing factors of clickbait and an interview using unstructured questionnaires inquiring about how it has influenced purchasing decisions. Fifty (50) respondents were conveniently selected for the survey, while ten (10) were similarly selected for the interview. The results gathered through the statistical application of Pearson-r correlation suggested that consumers consider the visual and psychological aspects of clickbait and are influenced by their purchasing decisions. Interview responses implied the apparent influence of a sensationalized headline in their purchases through various factors such as convenience, visually pleasing images or content, and the credibility and adequacy of the information being presented. The researcher recommended that online shops focus more on improving their virtual advertisements and utilize online survey questionnaires containing questions assessing customer satisfaction regarding their product, experience, and visual presentations. It is also advised that online shops conduct thorough research and in-depth application of the current trends. Consumers should be reminded and aware of those enticing advertisements that provide fake content.

Early Career Project Managers: Well-being and Life Satisfaction Analysis
Authors: Procházka David A. , Bočková Kateřina
Published: April 2024

The essentials of the presented paper are the psychological well-being and life satisfaction of early-career project managers (maximum 18 months of experience in project management). The primary goal is to determine whether there is a relationship between the psychological well-being and life satisfaction of early-career project managers, and if relationships exist between these variables, to determine their strength. In the theoretical part of the paper, processed using the analysis of relevant information sources, we deal with the concepts of well-being and life satisfaction. As part of the research description, we define an early carrier project manager and describe a sample of respondents consisting of 88 early carrier project managers. To analyze the well-being and life satisfaction variables, we use the Psychological Well-Being Scale questionnaire and the Life Satisfaction Scale questionnaire, where the results of these questionnaires are subsequently subjected to descriptive statistical analysis. We found that there is a moderately strong and statistically significant relationship between the psychological well-being and life satisfaction of early-career project managers. The results of the research can serve as a basis for developing suitable adaptation programs for early carrier project managers, where HR professionals can devote their attention to improving the well-being of early carrier project managers and their life satisfaction and thus reduce the risk of burnout syndrome, which is a very common phenomenon not only among early carrier professions but also project managers. The issue of well-being appears to be relatively well researched and described, even in the context of project managers. However, the life satisfaction of project managers has not been analyzed in such detail, and it is no longer possible to find the issue of investigating the mutual correlation of well-being and life satisfaction of early-career project managers. It is our research that can narrow this gap in the theories of project management, human resource management, and work psychology. Doi: 10.28991/ESJ-2024-08-02-06 Full Text: PDF

Published: April 2024

This study aims to develop an academic integrity scale to help lecturers evaluate the academic integrity of university students with peer-assessment learning experiences using the ADDIE research and development method. Twenty-four items were designed using the concepts of academic integrity; honesty, trust, fairness, respect, responsibility, and courage validated by six raters and tested on 520 students from various universities in Indonesia. Testing content validity using the Aiken-V formula, construct validity testing using discriminant indexes, factor analysis (Exploratory and Confirmatory Factor Analysis), and concurrent validity testing by correlating PAAIS-24 with the developed Academic Integrity Scale. While the reliability test used Cronbach's alpha formula. The study results proved that each item of content validity meets with an Aiken value >0.80; on construct validity testing, the discriminant index value is >0.50, and the EFA and CFA loading factor values are >0.50. In addition, the model is appropriate because the theoretical model of PAAIS-24 is in accordance with empirical data. Whereas in reliability testing, Cronbach's alpha value is 0.95. Lastly, PAAIS-24 is one of the credible instruments. It contributes to developing knowledge that assists lecturers in measuring, assessing, and evaluating student academic integrity based on peer-assessment to promote increased academic performance. Doi: 10.28991/ESJ-2024-08-02-09 Full Text: PDF
Domestic Workers’ Treatment and Rights Issues in Colonial Korea: 1920s~1930s
Authors:   The Association for Korean Modern & Contemporary History, LEE Ari
Published: April 2024

This paper explores the discussion on labor rights and human rights for domestic workers during colonial period, revisioning it as the origin of the discussion that has garnered recent attention in Korea.
During the Japanese colonial period when domestic workers first emerged, it brought up social issues regarding their treatment with the angle of labor right, abreast of increasing number of the Korean workers employed in Japanese households. From the mid-1920s onwards, it became noticeable that Korean women, often referred to as 'Omoni', were employed as domestic workers in Japanese households. At that time, Korean media portrayed such inter-racial employment negatively, urging Korean families to treat domestic workers well to keep them in Korean homes. However, despite these negative perceptions, predominantly expressed by Korean male intellectuals in the media, the reality revealed a preference among Korean women for working in Japanese homes due to higher wages and better working conditions.
While discourse on the treatment of domestic workers persisted, leading to the replacement of titles like 'Eomum' with 'Sikmo (housekeeper)' to mitigate lower-class connotations, there was a critical limitation in the discussion.
Specifically, it largely overlooked the plight of underage girls, who comprised the majority of domestic workers at the time, neglecting the genuine human rights issues surrounding them. Such historical traces echoes with the general flaw in discussions on domestic services in today, which still fail to adequately represent the voices of workers in the real world in policy discussions and to protect their rights.

Background: Tropical climate conditions and a lack of public awareness about maintaining environmental cleanliness mean that infectious diseases are still a major health problem in Indonesia. Bacteria, viruses, fungi and parasites are pathogenic organisms that cause infections. Fungal infections receive less attention because they are rarely fatal for the sufferer. Fungal infections in the ear, known as otomycosis, are often caused by Candida fungi. The Dewandaru plant (E. uniflora L) as a type of plant that is widely used for traditional medicine in the community is known to have antifungal potential. This plant contains flavonoids, alkaloids, terpenoids, anthraquinones and tannins which have antifungal properties. Method: The method used in this research was experimental research with a post test only control group design on C. albicans test material. The positive control was 1% Clotrimazole suspension and the negative control was 96% ethanol solution. Result: Research showed that there was an inhibitory effect of E. uniflora L leaf extract in concentrations of 100%, 90% and 80% against the Candida albicans fungus. Average diameter of the inhibitory area of leaf extract E. uniflora L concentrations of 100%, 90% and 80% respectively were 22.2 mm; 19.0mm; and 18.0 mm, while the average diameter of the 1% Clotrimazole inhibition area was 31.8 mm. Conclusion: There is an inhibitory effect of Dewandaru leaf extract (E. uniflora L) in concentrations of 100%, 90% and 80% against the Candida albicans fungus.

Our GraphoMatch project aims to revolutionise forensic handwriting analysis with Convolutional Neural Networks (CNN) and machine learning. Making it simpler and more trustworthy to determine who authored a writing piece or if a signature is authentic or not. We can examine handwriting samples closely using CNNs, which helps us get beyond some arbitrary guessing often used in this industry. Within the world of forensics machine learning, pattern recognition is part of a larger study field. This field has been growing with the help of a newer age framework and machine learning technologies. An average human writing is very predictable with more than 90% of differences that can be predicted using machine learning. Our project aims to improve that difference with more data and image training to make our model near-perfect for classification.

Since the advent of the internet and the digitization of information, more individuals and organizations have gained access to the internet, leading to a significant expansion in the size of our database systems. These databases are relied upon for day-to-day activities by individuals and organizations. Furthermore, the advancements in technology have increased the vulnerability of database management systems and enforcing adequate database security measures is of paramount importance to individuals and organizations. In this study, we deployed a hybrid approach to database security system that integrates two techniques: dynamic time-warping algorithm and voice recognition methods. The implementation follows Object-Oriented Analysis and Design procedures, utilizing SQL Management Studio 2014 for the backend and ASP.NET C# for the frontend. Our hybrid approach demonstrates enhanced database security compared to previously employed authentication measures.

Background: Exercise stress testing (EST) is a safe and cost-effective screening test for coronary artery disease (CAD) that does not require invasive procedures. Careful patient selection is essential for accurate results, but not recommended for women in their reproductive years due to a higher rate of false positives. This study aims to determine the gender difference and temporal profile of patients presenting for EST in southern Nigeria. Method: This was a retrospective study of 102 subjects at GoodHeart Medical Consultant Hospital from October 2019 to January 2023 focused on adult patients with low or intermediate pretest symptoms referred for EST. Data on medication, smoking, alcohol, and presenting symptoms was collected. Results: 102 subjects were studied (mean 49±16 years, 72.5% males). Most subjects (57.8%) were aged 41-60. The average duration of the EST was 9 minutes. Chest pain was the main reason for referral, and muscle fatigue was the most common reason for stopping the EST. The highest stage recorded was stage 3 (37.3%), and the lowest was stage 5 (3.9%). Over half of the subjects had a normal result, while 6.9% had ST changes and 3.9% had T wave inversion. Stress-induced ischemia was found in 7.8% and stress-induced arrhythmia in 3.9% of subjects, the study recorded a high prevalence among the males with no significant gender difference. Conclusions: Stress ECG testing had no injuries or deaths, with over half having normal results. Ischemia and arrhythmia were rare, and muscle fatigue was the main reason for stopping.

This study aimed to assess the inhibitory effectiveness of garlic products on fungi associated with cowpea, sorghum, maize, and groundnut seeds. The in-vivo evaluation involved a seed culture bioassay treated with garlic aqueous extract, while the in vitro antifungal activity of the extract on the radial growth of isolated fungi was determined using the agar well diffusion method. The treatments included garlic powder, garlic paste, garlic powder + molasses, garlic aqueous extracts at 100%, garlic aqueous extracts + adjuvant, and Thiram® (a synthetic fungicide). On untreated cowpea seeds, Aspergillus niger was the most frequently isolated fungal species, with an incidence of 61.5%. Cowpea seeds treated with 100% garlic extracts showed zero incidence of fungal colonies, whereas sorghum seeds + garlic aqueous extract displayed only A. niger. The in vitro study revealed that the inhibitory effect of 100% garlic aqueous extracts + adjuvant on the radial growth inhibition of A. niger, A. flavus, and P. chrysogenum was 78.86%, 70.40%, and 67.36%, respectively. In contrast, the inhibition by garlic powder + molasses and the control was significantly lower (p≤0.05) than other treatments. In conclusion, this study suggests that garlic extracts could be a potential source of organically-based natural fungicides for safeguarding crop seeds.

Onychomycosis is a fungal infection caused by dermatophyta and non-dermatophyte groups which infect the toenails or fingernails. Onychomycosis infection can lead to the damage of the nails which causes the nail thickness, brittle, and easily destroyed. Rhizopus sp. is considered to be one of the fungal species in the non-dermatophyte fungal infection group in the disease Onychomycosis. This study aims to determine the differences in the growth of non-dermatophyte fungi that cause onychomycosis infections on SDA and PDA media in samples of toenails from construction workers in Lamongan Regency. The research method used is descriptive, and the sampling technique used is random sampling. The sample size examined was 15 construction workers in duplicate, 15 planted in PDA media and 15 planted in SDA media. The material for this examination is scrapings from the toenails of construction workers which are planted directly on SDA and PDA media, then followed by macroscopic and microscopic examination. Based on macroscopsic examination, it was found that the colonies were white to grayish white, had a cotton-like surface and were spreading. Based on microscopic examination using the addition of 1 drop of LCB dye reagent, fungal elements were obtained which indicated the non-dermatophyte fungus Rhizopus sp. namely there are stolon, rhizoid, sporangiospore, sporangium and apoplysis. From the results of this research it can be concluded that there is growth of the fungus Rhizopus sp. non-dermatophyte group on PDA media and SDA media, there was no difference in the growth of non-dermatophyte fungi that cause onychomycosis in the toenails of construction workers in Lamongan Regency on PDA media and SDA media and there was a difference in the growth of the fungus Rhizopus sp. Non-dermatophyte groups causing onychomycosis based on age.
