Topological semimetals A3Sn (A = Pt, Pd), exhibiting nontrivial band inversion and weak topological Dirac/Weyl band crossings, are investigated for the first time with a focus on their thermoelectric (TE) performance through electronic band structure calculation from the viewpoint of spin-orbit coupling (SOC) and finite temperature (T) anharmonicity. Both compounds show semimetallic character with flat or near-flat bands along the Gamma-X line of the L12 structure Brillouin zone, promoting carrier asymmetry and improved Seebeck coefficient. A sharp feature in the total electronic density-of-states (e-DOS) near the Fermi level (E F) induces a subtle thermal redistribution of occupancies at low temperatures, producing changes in electronic pressure and affecting transport. SOC splits Pt/Pd d and p orbitals, respectively, into j = 3/2, 5/2 and j = 1/2, 3/2 (in terms of & hbar;) sublevels, smoothing out e-DOS features. Beyond perturbative effects, SOC also modulates anharmonicity, where directional Pt/Pd d orbitals and spin (S) interact to modulate the nonharmonic character of interaction potential, which at elevated temperatures enhances TE performance. These observations are analyzed and confirmed by systematic study of projected electronic density-of-states (PDOS) and various TE parameters. The ZT and power factor (PF) maxima of Pt3Sn occur within a narrow energy window around E F, reflecting its more metallic character. For Pd3Sn, ZT is almost zero in the vicinity of E F and has finite values deep in conduction and valence bands, reflecting its broader energy range for effective carrier asymmetry. At 1000 K, the ZT and PF values reach 3.326 and 7.912 for Pt3Sn and 4.030 and 7.071 for Pd3Sn, respectively, at optimal carrier concentrations, highlighting the superior performance of p-type Pd3Sn. These findings demonstrate that SOC, orbital hybridization, and anharmonicity collectively govern electronic transport and TE efficiency, making these L12-type intermetallics promising candidates for high-T TE applications.

While examining electronic literature as post comparative media, Astrid Ensslin and Samya Brata Roy characterised electronic literature as a "pluralistic, fluid phenomenon that challenges the established norms and analytical frameworks of traditional literary practices". (Ensslin & Brata Roy [2023]. Electronic literatures as post comparative media. Complit Journal of European Literature, Arts and Society, 1(5), 145-171) This perspective underscores the need to examine electronic literature within specific socio-cultural contexts. Therefore, this paper contextualises the Electronic literary praxis within a creative writing workshop conducted with postgraduate English language and literature students at the Department of English, Maharaja Krishnakumarsinhji Bhavnagar University, Gujarat, India; through which the students were introduced to the process of building a hypertext using Twine, a free and open-source tool, to construct interactive narratives, drawing on the learning experiences of the primary author of this manuscript. Following the instruction, students engaged in a creative writing assignment, developing their own hypertextual stories. The paper reviews student feedback received through feedback forms completed by all participants and interviews with those who created hypertexts after the workshop. It argues that electronic literature in pedagogy promotes innovative narrative exploration while developing creativity, critical thinking, reading, and writing skills in digital contexts. Concluding, it recommends a creative writing-based, practice-oriented framework for teaching electronic literature in the Indian academic context.

This study examines the physicochemical behaviour of a system composed of the anionic azo dye Fast Sulphon Black F (FSB F) and the nonionic micelle-forming species Polysorbate 80 (P80). Density, viscosity, and acoustic measurements were performed at 303.15, 313.15, and 323.15 K over surfactant concentrations of 0.002-0.020 mM in a 2.0 mM dye solution. From these data, the critical micelle concentration (CMC) and related interaction parameters were evaluated. UV-vis spectroscopy indicates the formation of dye-surfactant ion-pair complexes in the pre-micellar region, followed by predominant dye solubilization within micelles above the CMC. Dynamic light scattering (DLS) confirmed changes in aggregate size and solution stability upon dye incorporation. FTIR analysis further supports functional group interactions between the dye and micellar environment. Variations in acoustic parameters highlight the contributions of pi-pi stacking and hydrophobic forces to dye-micelle association. Overall, the results demonstrate significant structural and energetic interactions between FSB F and micellar assemblies, as quantified by Gibbs free energy of phase interaction, offering broader insight into solubilization mechanisms relevant to formulation and solution chemistry.

Background Iron-deficiency anemia (IDA) is a leading cause of adverse maternal and neonatal outcomes, particularly in resource-limited settings where nutritional deficits and late antenatal presentation are common. When diagnosed in late gestation, oral iron therapy is often insufficient for timely hematologic correction. Methods This retrospective observational study reviewed medical records of 75 pregnant women between 26 and 32 weeks of gestation with hemoglobin <9 g/dL who had received intravenous iron sucrose as part of routine clinical care. Baseline and six-week post-treatment hematologic parameters, along with maternal delivery outcomes and neonatal indicators, were extracted from existing hospital records. Statistical analyses included paired t-tests, chi-square tests, and effect size estimation. Results Intravenous iron sucrose produced a substantial and statistically significant improvement in hematologic parameters, with clear correction of microcytic indices by the six-week follow-up. The therapy was well tolerated, with only minor infusion-related events and no serious adverse reactions. Maternal delivery patterns were largely favorable, and neonatal outcomes - including birthweight distribution and need for intensive care - were consistent with improved perinatal stability following effective anemia correction. The observed hematologic improvements were consistent across recorded demographic profiles, reinforcing the reliability of the findings in nutritionally vulnerable populations. Conclusion Intravenous iron sucrose provides rapid, clinically meaningful correction of IDA in late pregnancy. No serious adverse events were documented in the available medical records. These findings support its integration into antenatal anemia management, particularly where oral iron is inadequate or poorly tolerated, and highlight its potential to reduce anemia-associated maternal-fetal morbidity. The retrospective design further reflects the real-world clinical effectiveness of iron sucrose in late-gestation anemia.

A series of indole–pyrazole Schiff base conjugates was synthesized and biologically evaluated, revealing notable antioxidant and antibacterial activities. In free radical scavenging assays, several derivatives exhibited concentration-dependent efficacy, with specific fluorinated, nitrated and methoxy substituted analogues demonstrating the strongest antioxidant performance in both DPPH and hydrogen peroxide scavenging assays, achieving high levels of radical inhibition at 5 mg/mL relative to standard ascorbic acid. Antibacterial screening against S. aureus, E. coli, P. polymyxa, and P. aeruginosa identified key active derivatives exhibiting substantial growth inhibition across multiple strains, with P. aeruginosa displaying exceptional sensitivity. Molecular docking studies corroborated the experimental findings, demonstrating favorable binding interactions of the lead compounds within the active sites of bacterial DNA gyrase targets. Notably, the 4-fluorobenzylidene derivative displayed the highest binding affinity toward both S. aureus DNA gyrase and P. aeruginosa DNA gyrase B, driven by strong and stable ligand–protein interactions. Validation of the docking protocol via self-docking of co-crystallized ligands yielded acceptable root-mean-square deviation (RMSD) values (<3 Å), confirming the predictive reliability of the computational model. Overall, the integrated biological and computational insights underscore the lead fluoro-substituted hybrid as a promising multifunctional candidate, demonstrating that strategic aryl ring substitutions on the indole–pyrazole framework critically modulate both antioxidant and antibacterial potency.
