This review comprehensively examines the extraction of lithium from lepidolite via the sulfate roasting method. As demand for lithium, particularly for lithium-ion batteries, continues to grow, the exploitation of lithium-bearing minerals like lepidolite has become increasingly important. The sulfate roasting process, involving mixing, roasting, water leaching, purification, and precipitation, is highlighted as a promising industrial method due to its high lithium recovery efficiency and relatively low environmental impact compared to alternatives like acid digestion or chlorination roasting. Notably, the process allows for the effective management of toxic by-products such as fluorine (via fixation) and thallium (via targeted removal), which is crucial for sustainable operation. The review details the critical factors affecting lithium yield, such as the particle size of lepidolite, the type and ratio of sulfates (e.g., Na₂SO₄, K₂SO₄, CaSO₄, FeSO₄), roasting temperature and duration, and leaching conditions, and discusses the underlying mechanisms, primarily ion exchange and mineral decomposition. Furthermore, it addresses the potential for co-extraction of valuable by-products like rubidium and cesium and identifies future research directions, including reducing energy consumption and optimizing additives for improved efficiency and sustainability.

Nosocomial infections caused by Pseudomonas aeruginosa (P. aeruginosa) display a significant threat with high levels of multi-drug resistance against current antibiotic treatments. Beta-lactamases (BLs) are major contributors to resistance acquisition against beta-lactams. Pseudomonas-derived cephalosporinase (PDC-3) and New Delhi Metallo beta-lactamases (NDM-1) are frequently occurring BLs in Carbapenem Resistant P. aeruginosa (CRPA) population, in India. The study evaluates phytocompounds for their beta-lactamase inhibitory potential against PDC-3 and NDM-1 of P. aeruginosa, employing an in-silico approach. Phytocompounds were screened for their drug likeness based on pharmacokinetic and toxicity parameters, followed by molecular docking, molecular dynamics simulations, and density functional theory analyses. Carotol emerged as the most promising candidate, possessing favourable docking scores of −5.92 kcal/mol and − 5.94 kcal/mol with PDC-3 NDM-1, respectively. Molecular dynamics simulations further confirmed stable and consistent interactions of carotol with both enzymes. Although the in vitro validations would strengthen the proposal of carotol as a potent beta-lactamase inhibitor.

Pesudopolymorphism/polymorphism significantly impacts the physical properties of crystalline materials, making the discovery and characterization of new pesudopolymorphs/polymorphs crucial for material science. This study aimed to characterize a newly discovered pseudopolymorph of 3,3′-(4-amino-4H-1,2,4-triazole-3,5-diyl)diphenol (β-3OH) obtained from ethanol crystallization, compare its structural and physicochemical properties with the known methanol-derived polymorph (α-3OH), and determine their relative stability. The novel β-3OH was characterized using single-crystal X-ray diffraction (SCXRD), infrared (IR) spectroscopy, ultraviolet-visible (UV–vis) spectroscopy, powder X-ray diffraction (PXRD), and differential scanning calorimetry (DSC). Hirshfeld surface analysis and energy framework calculations were employed to understand intermolecular interactions and lattice energies. SCXRD revealed β-3OH crystallizes in the monoclinic I2/a space group. Structural analysis showed different hydroxyl group orientations and molecular conformations (cis/trans isomers) compared to α-3OH. β-3OH exhibited a higher luminescent emission maximum (428 nm vs. 414 nm for α-3OH). Hirshfeld surface analysis correlated larger stacking distances and phenyl-triazole dihedral angles in β-3OH with specific C⋯H/C⋯C contacts. DSC data and fusion rules determined β-3OH shows a monotropic relationship. Energy framework calculations demonstrated significantly stronger intermolecular interactions (electrostatic, dispersion, polarization, repulsion, total) in β-3OH. Comprehensive characterization confirms the successful isolation of a new pseudopolymorph, β-3OH. The combined structural, spectroscopic, thermal, and computational analyses consistently demonstrate that β-3OH is thermodynamically more stable than α-3OH, attributed to its enhanced network of intermolecular interactions.

The green synthesis of Zinc Oxide Nanoparticles (ZnO NPs) has garnered significant attention due to its eco-friendly nature and the versatile applications of ZnO NPs in various fields. This review delves into the latest advancements in green synthesis methods, emphasizing plant extracts, microorganisms, and biomacromolecules (notably proteins and peptides). By integrating bibliometric analysis of Web of Science data (2015–2025), it pinpoints global research hotspots like “green synthesis,” “antibacterial activity,” and “photocatalysis.” Key insights include: plant-mediated synthesis offers cost-effectiveness but is affected by seasonal variability; microorganism-driven approaches allow for scalability yet require strict sterility; and biomacromolecules-mediated methods. Critically, we highlight how artificial intelligence (AI), particularly machine learning (ML), is being integrated across these methods—from predicting optimal plant extract compositions and microbial culture conditions to designing peptide templates—to enhance reproducibility, yield, and functionality of green-synthesized ZnO NPs. The bibliometric analysis reveals India and China as research hubs, with “Good Health and Well-Being” being the dominant sustainable development goal (4720 publications). The synthesis of sustainable chemistry and AI promises future breakthroughs in large-scale, tailored ZnO NPs production for applications in biomedicine and environmental protection. This review provides a comprehensive analysis integrating green synthesis techniques with scientometric insights, offering a critical assessment of ZnO NPs sustainability and its role in advancing global health solutions.

This study explores the physicochemical properties, nanoscale characteristics, and biological activity of ultra-diluted homoeopathic medicines (Ocimum sanctum and Curcuma longa) at different potencies using advanced analytical techniques. Our purpose of this work was to examine the presence of nanoparticles which present inside the medicines even at the ultra-dilutions. The medicinal efficacy of ultra-high diluted homoeopathic medicines remains a contentious issue in the scientific community. Because dilutions beyond Avogadro's limit are believed to lack active molecules. Two widely used homoeopathic medicines—Ocimum sanctum (OS) (3×, 6×, and 3CH) and Curcuma longa (CL)—at potencies of 3×, 6×, and 6CH were investigated using advanced analytical techniques including UV–Visible spectroscopy, FT-IR spectroscopy, Transmission Electron Microscopy (TEM), and artificial intelligence (AI)-based analysis. These methods identified distinct absorption peaks, functional groups, and the presence of nanoparticles in all potencies, confirming the structural integrity and preservation of medicinal fingerprints even at high dilutions. Additionally, acoustic and physicochemical studies were conducted by measuring density, ultrasonic velocity, and viscosity of the medicines in 90 % ethanol–water at temperatures ranging from 293.15 K to 318.15 K. These measurements allowed derivation of thermodynamic and acoustic parameters to understand solute–solvent interactions. The results revealed strong molecular interactions between the medicinal compounds and water–ethanol aggregates, indicating the role of potentization in preserving active structures. AI-based data analysis confirmed presence of nanoscale particles across all potencies. Furthermore, antibacterial assays against both Gram-positive and Gram-negative bacteria demonstrated significant inhibitory activity for all OS and CL medicines, while control samples showed no antibacterial effect. This study provides strong physicochemical and biological evidence for the presence of active constituents in ultra-diluted homoeopathic medicines.

The effect of the bimetallic Zn(Cr, Y)SiBEA zeolite (Si/Al = 1000) compositions on the preferred pathway of the CO2-PDH process, as well as the catalysts' activity and selectivity in direct propane dehydrogenation (PDH) and reverse water-gas shift reaction (RWGS), has been examined. Analysis of the surface functional (redox and acid-base) characteristics reveals that balanced acid-base properties determine the catalysts' activity and selectivity in both the main process and the component reactions—direct propane dehydrogenation and RWGS. High propene selectivity is observed on Zn2.0SiBEA (94 %) and Cr1.0/Zn1.0SiBEA (89.5 %) catalysts, due to alkane activation at acid-base sites and CO2 activation on base sites. This suggests that the primary pathway of the CO2-PDH process on these bifunctional catalysts involves PDH combined with RWGS.

Antimicrobial textiles have gained noteworthy attention due to their prospective applications in healthcare, hygiene, and everyday use. This study explores the efficacy of ZnO/SnO2/rGO nanocomposite coated on cotton fabrics pre-treated with argon plasma for enhanced antibacterial as well as anticancer activity. X-ray diffraction (XRD) was employed to determine the crystalline structure and phase composition, providing insights into the materials crystallinity and potential phase transitions. Fourier transform infrared (FTIR) spectroscopy was used to identify the functional groups present in the samples. Scanning electron microscopy (SEM) was conducted to examine the surface morphology and microstructural features. Additionally, energy-dispersive X-ray (EDX) analysis was integrated with SEM to assess the elemental composition and distribution across the sample surface. The wettability characteristics were evaluated using Contact Angle (CA) measurements, which provided information on wettability. To assess the mechanical properties, tensile strength testing was performed. Lastly, air permeability measurements were carried out to evaluate the breathability of the material, which is crucial factor of antimicrobial fabrics. Current research explores the antibacterial properties as well as anticancer activity (A549).
