Exploring the in‐situ Development of A 1 D/2 D Gadolinium Iron Oxide/Tungsten Disulfide Photocatalyst to Improve Tetracycline Degradation Mediated by Visible Light
Authors: Preetha Rajaraman , Bosco Aruljothy John 
Published: May 2024

AbstractIn the field of photocatalysis, heterojunction photocatalysts have garnered a lot of attention due to their high‐efficiency interfacial charge‐transfer property and their nanoarchitecture. Herein, GdFeO3/WS2 is successfully synthesized by the in‐situ growth method and holds significant catalytic properties and efficient degradation for tetracycline. Using WS2 as a co‐catalyst could reduce e‐ and h+ recombination, improving GdFeO3’s photocatalytic performance. The GdFeO3/WS2 possesses a bandgap of 1.9 eV, 178.9 m2 g−1 specific surface area, 0.2 nm pore size, and a lifespan of 6 ns. The optimal GdFeO3/WS2 photocatalyst exhibits a maximum removal of 96.2 % at a tetracycline concentration of 10 mg/L, a pH of 3, and 40 mg of photocatalyst in an irradiation time of 90 min. Tetracycline has a higher photocatalytic efficiency in visible light (96.2 %) than in sunlight (72.6 %). Trapping tests revealed that the major reactive species for tetracycline removal in an aqueous solution are ⋅⋅OH, and ⋅⋅O2‐. The recycle experiment shows no deactivation of the GdFeO3/WS2 photocatalyst after 5 recycles. This study sheds light on the rational design of the GdFeO3/WS2 photocatalyst as a potential material for treating wastewater.

Published: May 2024

SummaryThe ability of facial expression recognition, the ability to decipher human emotions from facial features, and we can judge the emotional state of human beings by analysing facial expressions. Empowered by this technology, the related research of student sentiment analysis has become a focal point in the realm of educational technology. Teachers can now read the emotional state of their students and estimate the effectiveness of their teaching strategies, enabling them to implement appropriate intervention techniques to enhance teaching outcomes. However, facial expression recognition techniques are currently limited by their shortcomings. Network performance degradation and loss of feature information are key issues that hinder the effectiveness of sentiment analysis of student feedback. To overcome these limitations, in this paper, we propose RFMNet, a novel network model based on deep learning theory. RFMNet, with its higher extraction capability, is designed to accurately analyse student expressions. It introduces a relation‐aware global attention (RGA) module, which facilitates the integration of more discriminative expression features in the image, leading to more refined sentiment analysis. This innovative model also employs a Mish activation function and a focal loss function. The Mish activation function is of particular interest because it helps to avoid the loss of feature information due to neuron deactivation when the ReLU gradient is . This approach results in a more robust and accurate facial expression recognition model. Our model was tested on the FERPlus public dataset. The model achieved an average recognition accuracy of 89.62%, which is a testament to its performance in decoding the facial expressions of students. This precision allows for intelligent processing of teaching information and real‐time feedback, enabling teachers to adapt their teaching strategies to better suit the needs of their students.
Mediation as a 21st century conflict resolution mechanism: Exploring procedural fairness experiences of mediation users in Ghanaian courts
Authors: Benson George Hika , Asaah‐Junior Stephen Kwabena 
Published: May 2024

AbstractMediation has become a contemporary conflict resolution mechanism in the 21st century that offers an alternative to traditional legal processes. This qualitative study explores the experiences of mediation users in three courts in the Central Region of Ghana, with a focus on procedural fairness. Grounded in the theory of procedural fairness, the study examines how Ghanaian and African conceptions of fairness influence mediation practice. The study found that the Ghanaian and African understanding of procedural fairness is rooted in specific situations—taking into account parties' demands in generating settlement agreements, allowing parties to select their mediators, involving important personalities in mediation, ensuring the fair settlement of cases, and deciding who should speak first. Participants evaluated procedural fairness within the context of confidentiality, neutrality, party empowerment, and the assurance of being heard. These evaluations align with what has been reported in Western literature. This research contributes to the growing body of literature on conflict resolution by providing insights into the significance of procedural fairness within mediation practice, with specific reference to Ghana. The findings underscore the importance of aligning mediation processes with principles of procedural fairness, offering valuable lessons for practitioners, policymakers, and researchers who seek to optimize the efficacy and fairness of mediation as a conflict resolution mechanism.
Research on the impact and mechanisms of lean management on the green development of traditional small and micro manufacturing enterprises
Authors: Qianqiu Yang , Baoli Song 
Published: May 2024

AbstractTo achieve the “dual carbon” goals, manufacturing businesses must pursue green development. Compared to larger enterprises, the path towards green development is fraught with difficulties for the numerous traditional small and micro manufacturing enterprises. Lean thinking offers new solutions to the pain points and challenges of green development for these enterprises. However, existing research primarily focuses on large enterprises, with limited studies on traditional small and micro manufacturing enterprises; moreover, the conclusions on lean green development remain contentious and fail to effectively guide these enterprises through their green development bottlenecks. Therefore, this paper constructs a lean green development mechanism model for traditional small and micro manufacturing enterprises based on the grounded theory research method and the “resource‐behavior‐performance” model. It validates the model with empirical data from 333 traditional small manufacturing enterprises in China. The results show that in the actual development process of traditional small and micro enterprises, implementing lean organization and lean production significantly improves environmental performance, but the impact on economic performance is complex. Additionally, the influence of lean strategies on green development performance is not significant, not fully realizing their potential guiding role. Further in‐depth analysis of traditional small and micro manufacturing enterprises with a mature level of lean management reveals that as the level of lean management improves, the guiding effect of lean strategies begins to emerge; both lean organization and production have a significantly positive impact on economic performance. The findings are theoretically and practically significant for overcoming the green development challenges faced by traditional small and micro manufacturing enterprises, help to broaden the research scope of lean green development, and provide decision‐making and theoretical support for promoting the seamless implementation of lean green development in the traditional manufacturing sector.
Rare heterozygous genetic variants of NRXN and NLGN gene families involved in synaptic function and their association with neurodevelopmental disorders

Published: May 2024

AbstractThe interaction of neurexins (NRXNs) in the presynaptic membrane with postsynaptic cell adhesion molecules called neuroligins (NLGNs) is critical for this synaptic function. Impaired synaptic functions are emphasized in neurodevelopmental disorders to uncover etiological factors. We evaluated variants in NRXN and NLGN genes encoding molecules located directly at the synapse in patients with neuropsychiatric disorders using clinical exome sequencing and chromosomal microarray. We presented detailed clinical findings of cases carrying heterozygous NRXN1 (c.190C > T, c.1679C > T and two copy number variations [CNVs]), NRXN2 (c.808dup, c.1901G > T), NRXN3 (c.3889C > T), and NLGN1 (c.269C > G, c.473T > A) gene variants. In addition, three novel variants were identified in the NRXN1 (c.1679C > T), NRXN3 [c.3889C > T (p.Pro1297Ser)], and NLGN1 [c.473T > A (p.Ile158Lys)] genes. We emphasize the clinical findings of CNVs of the NRXN1 gene causing a more severe clinical presentation than single nucleotide variants of the NRXN1 gene in this study. We detected an NRXN2 gene variant (c.808dup) with low allelic frequency in two unrelated cases with the same diagnosis. We emphasize the importance of this variant for future studies. We suggest that NRXN2, NRXN3, and NLGN1 genes, which are less frequently reported than NRXN1 gene variants, may also be associated with neurodevelopmental disorders.

AbstractLithium metal batteries (LMBs) are recognized to be crucial for secondary battery technology targeting electric vehicles and portable electronic devices. However, the undesirable growth of lithium dendrites would result in reduced capacity, short‐circuit, and overheating, seriously hindering the practical applications of LMBs. To address this issue, a neoteric lithiophilic interlayer on a commercial polypropylene separator is presented for the first time, which is constructed by amorphous CoB nanoparticles decorated reduced graphene oxide nanosheets (CoB@rGO). Density Functional Theory calculations and experimental analysis reveal remarkable lithiophilicity features for CoB@rGO and provide multiple Li deposition sites and improved electrolyte wettability, which facilitates the formation of durable solid electrolyte interphase (SEI), reduces side reactions, and improves Li+ flux regulation for long‐term cycling stability in LMBs. Taking advantage of these merits, the symmetric Li//Li cell with CoB@rGO/PP separator exhibits stable cycling for up to 1600 h at 1 mA cm−2 with 1 mAh cm−2. Employed with CoB@rGO separator, the Li//LiFePO4 full cell with a high LiFePO4 loading of 11 mg cm−2 delivers a high initial specific capacity of 115.3 mAh g−1 and a low decay rate of 0.08% per cycle after 200 cycles even at a high rate of 2C.

Published: May 2024

AbstractIn the past, the use of nitrogen ylides focused primarily on cycloadditions, where the 1,3‐dipole was used as a building block for the formation of heterocycles such as pyrroles or pyrrolinones. In this work, we present a new perspective on imidazolium dicyanomethylides with their synthesis and utilization as anionic N‐heterocyclic carbenes (NHCs). The values of relative carbene formation energies (CREF) for a wide range of substituted imidazolium ylides unknown in the literature showed promising properties. In situ trapping reactions of these anionic NHCs with selenium led to anionic, water‐soluble compounds that exhibited remarkable coordination behavior according to X‐ray structure analyses. In addition, the 77Se shifts of the investigated compounds were measured to draw conclusions about their π‐acceptance.
EDA Complex from BCP‐Thianthrenium Salt: A Catalyst‐Free Strategy To Access 1‐Trifluoromethyl‐3‐quinoxaline Derivatives Bicyclo[1.1.1]pentanes
Authors: Zhang Guofu , Luo Zijin , Mei Guangyao , Wang Haibo , Ding Chengrong 
Published: May 2024

AbstractThe construction of bicyclo[1.1.1.]pentanes (BCPs) typically require the cumbersome use of labile [1.1.1.]propellane in solution and involve multicomponent radical reactions, which commonly produce undesired by‐products that hinder the efficient construction of BCPs. In this paper, we present a catalyst‐free strategy by constructing an electron donor‐acceptor (EDA) complex utilizing the naturally electron‐deficient nature of BCP thianthrenium salt, which were irradiated with visible light to obtain trifluoromethyl‐BCP radicals through a SET process, subsequently reacted with various substituted quinoxalines. Moreover, the successful structural modification of drug molecule derivatives confirm the utility of this scheme in the field of drug discovery.

Published: May 2024

AbstractThe viability detection of microalgae with the electrokinetic (EK) technique shows vast applications in the biology and maritime industry. However, due to the slight variations in the EK properties between alive and dead microalgae cells, the accuracy and practicability of this technique is limited. In this paper, the light illumination pretreatment was conducted to modify the EK velocity of microalgae for enhancing the EK difference. The effects of the illumination time and light color on the EK velocities of Chlorella vulgaris and Isochrysis galbana were systematically measured, and the EK differences between alive and dead cells were calculated and compared. The results indicate that under light illumination, the photosynthesis of the alive cells leads to the amplification of the zeta potential, leading toward increase in the EK difference along with the illumination time. By using light with different color spectra to treat the microalgae, it was found that the EK difference changes with the light color according to the following order: white light > red light > blue light > green light. The difference in EK potential with exposure to white light treatment surpasses over 10‐fold in comparison to those without such treatment. The light pretreatment technique, as illustrated in this study, offers an advantageous strategy to enhance the EK difference between living and dead cells, proving beneficial in the field of microalgae biotechnology.

Published: May 2024

AbstractNatural gas pipelines are exposed to complex production and transportation environments, leading to blockages of varying compositions and forms due to various factors. This paper proposes a pressure pulsing wave‐based pipe blockage detection method, and a series of pipeline blockage detection experiments of different materials are carried out, including hydrate blockage, ice blockage, paraffin blockage, and water blockage. Through the blockage detection calculation theory and the reflection and transmission characteristics during pressure wave emission, the blockage position, length, and section blockage rate under different blockage materials are obtained, and the influence of different blockage materials on the reflection and transmission signal characteristics of the pressure pulse wave is analyzed. The results show that the solid blocking material does not noticeably impact the reflectivity and reflective properties of pressure waves, and different cross‐sectional shapes have a noticeable impact on the reflectivity of the pressure wave. The reflected wave waveform of the liquid blockage material is visible but irregular. The average error of blockage location is 0.78%.
Pore morphology changes and quantitative analysis and evaluation of high‐rank coal samples after impact
Authors: Wang Yixian , Han Qijun , Yue Jiwei 
Published: May 2024

AbstractThe influencing mechanism of impact loads on the pore morphology of high‐rank coal has been extensively investigated since mining safety is greatly determined by the ensuing state of gas occurrence. In this work, we propose a combined use of a scanning electron microscope and Image Pro Plus software to examine the impact‐induced changes in pore characteristics. Impact loads of 0, 28.46, 51.8, and 58.7 MPa were applied to the coal samples in various directions (parallel/vertical/45° oblique). The results show that the pore connectivity of coal samples is enhanced following the impact load, and the number and diameter of pores are significantly increased on the whole. Surface porosity and roundness of the coal body first rise and then fall as the impact load increases. Following the impact load, surface porosity and roundness of the coal body significantly increase in the vertical and oblique bedding directions, while decreasing in the horizontal bedding direction.
A multistage forecasting model for green bond cost optimization with dynamic corporate risk constraints
Authors: Hu Zinan , Yang Ruicheng , Borjigin Sumuya 
Published: May 2024

AbstractThis study develops a multi‐stage stochastic model to forecast the issuance of green bonds using the Filtered Historical Simulation (FHS) method to identify the most cost‐effective conditions for issuing these bonds amid various risk factors. Drawing on historical yield data and financial metrics of corporate green bonds from December 2014 to June 2023, the model considers fluctuating elements such as risk probabilities, financial risks in worst‐case scenarios, and liquidity risks at upcoming issuance moments. Our findings reveal the model's effectiveness in pinpointing the lowest possible costs of issuing new green bond portfolios in the future, while also addressing expected financial risk, risk occurrence probability, and liquidity issues. The results provide issuers with the insights needed to accurately time the market, tailor bond maturities according to a corporation's future risk profile, and enhance liquidity management. Notably, our model indicates that refining the estimated probability of future risk occurrences can lead to significant savings in green bond issuance costs. This approach allows for adaptable bond issuance strategies, addresses inherent debt, and enables detailed risk management, offering substantial benefits for green enterprises navigating the complexities of future financial landscapes.
Time‐varying risk preference and equity risk premium forecasting: The role of the disposition effect
Authors: Qiao Kenan , Xie Haibin 
Published: May 2024

AbstractThis study examines whether the disposition effect can explain time‐varying risk preference and predict the equity risk premium. To do so, we propose an augmented general autoregressive conditional heteroskedasticity (GARCH)‐in‐Mean model unraveling the complex relationship between unrealized gains/losses, realized returns, and the equity risk premium. In our model, the risk aversion coefficient varies with the market state of unrealized gains/losses. Using data from the US stock markets, we show strong evidence that the disposition effect drives time‐varying risk preference: The risk aversion coefficient is significantly positive during periods of unrealized gains, but insignificant during periods of unrealized losses. These findings reconcile the conflicting results of the risk‐return trade‐off in existing literature. Moreover, our model shows significant predictability of the equity risk premium, both in‐sample and out‐of‐sample. Incorporating our model's predictions can yield substantial utility gains for a mean‐variance investor. Our results indicate that the disposition effect leads to time‐varying risk preference and thus induces equity risk premium predictability.

Published: May 2024

AbstractPropolis is widely used as a supplementary food product for its health benefits. The aim of this study was to determine the effects of commercial propolis extracts on the liver and kidney. Propolis extracts (250 mg/kgbw/day) were administered orally to adult male Wistar albino rats in solvents of ethanol, propylene glycol, water, and olive oil. Liver enzyme levels were determined biochemically in blood samples, and histopathological examinations were performed on the liver. Damage rate in both kidney tissue in the propolis‐ethanol extract group increased significantly compared with the other groups after 30 and 90 days of application (p < .05). According to the results, ethanol, used as a common solvent in propolis products, may adversely affect the liver in long‐term use. The data indicate that propolis‐olive oil extract may be an essential alternative due to its effective and reliable properties.

Published: May 2024

AbstractOyster peptide (OP) and Pfaffia glomerata extract (PGE) were used as raw materials. The optimal formulation of the pressed candy (PC) was optimized by one‐way experiment and D‐optimal mixture experiment design, and animal experiment was used to evaluate the effect of PC on male sexual dysfunction. The results showed that PC intervention significantly improved the sexual behavior of male mice with sexual dysfunction, including a significant shortening of the mount latency (ML) and intromission latency, and a significant increase in the mount frequency (MF) and intromission frequency (IF). At the same time, the concentrations of serum testosterone (T) and luteinizing hormone (LH) in mice were restored, and the erectile parameters and pathological changes of penile tissue were improved. Further studies found that PC intervention increased the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH‐Px) and reduced the content of malondialdehyde (MDA) in testicular tissue. In addition, PC intervention improved testicular tissue morphology. In conclusion, the obtained PC has good taste quality, and the relevant quality indicators are qualified. It has a good ameliorative effect on male sexual dysfunction and may be a potential dietary supplement.
