This study demonstrates that sulfuric acid induces greater apparent mass reduction in lithium-bearing ore from Kishi, Nigeria, compared to hydrochloric acid and water under room-temperature leaching conditions, though the results reflect general dissolution rather than specific lithium recovery.
This study demonstrates that optothermal Raman thermometry, combined with multi-modal characterization, enables the preparation-free measurement of intrinsic grain-scale thermal conductivity and aromatic ordering in coal, revealing values significantly higher than bulk measurements and providing new spatially resolved descriptors across the coal rank series.
This study demonstrates that a Hibiscus-assisted SiO₂/TiO₂-stabilized emulsion liquid membrane system can effectively remove up to 96.35% of diazinon from synthetic aqueous solutions under optimized conditions, offering a sustainable extraction method that remains viable for up to three reuse cycles.
This study demonstrates that a room-temperature H₂S sensor based on a polypyrrole/MoO₃ heterojunction, prepared via in-situ polymerization, achieves significantly enhanced sensitivity, selectivity, and stability compared to pure polypyrrole by leveraging interfacial charge transfer and p-type doping to enable efficient hole-dominated transport without the need for high-temperature operation.
This study demonstrates that lightening and colouring conventional black bitumen is achievable through a low-cost, scalable process involving emulsification and the addition of light mineral phases for optical masking, which transforms the binder from black to grey and allows for effective tinting with reduced pigment usage.
This study demonstrates that incorporating 2% nano-silica into paraffin/urea-formaldehyde microcapsules via in-situ polymerization effectively enhances their mechanical strength, reduces supercooling, and mitigates formaldehyde leakage, thereby providing a high-stability solution for thermal energy storage in deep mine backfill applications.
This study demonstrates that a combined advanced oxidation technique utilizing TiO2 nanoparticles, photocatalysis, and photo-ozonation effectively removes organic pollutants from food industry wastewater with 90% efficiency, overcoming the individual limitations of light penetration and energy consumption while optimizing process parameters and assessing eco-toxicological impacts.
This study developed and validated a sensitive, rapid, and reliable high-performance thin-layer chromatography (HPTLC) method for the identification and quantification of β-sitosterol in the ethanolic extracts of *Indigofera cordifolia* aerial parts and roots, confirming its presence with high precision and accuracy.
This study reports the synthesis of CoNi-decorated biomass-derived carbon composites via a hydrothermal and thermal reduction approach, which achieve high-performance electromagnetic wave absorption through synergistic dielectric-magnetic loss mechanisms, yielding a minimum reflection loss of −50.17 dB and an effective bandwidth of 5.01 GHz at a thin thickness of 1.9 mm.
This study utilized FAAS to analyze seven metals in onion and rice samples from three districts in Northern Ethiopia, finding that while essential and toxic metal concentrations varied by location and crop type, all levels remained below WHO permissible limits, indicating a low current public health risk.
