This study reports the synthesis and characterization of a novel curcumin–isoniazid bis-hydrazone conjugate that demonstrates potent, concentration-dependent inhibition of HIV-1 reverse transcriptase with an IC₅₀ of 10.6 µM and favorable binding interactions, positioning it as a promising scaffold for further antiretroviral drug development.
This study investigates a two-stage catalytic pyrolysis process using an Fe/Al₂O₃ catalyst to simultaneously convert waste polypropylene into hydrogen-rich gas and high-quality carbon nanotubes, aiming to optimize reaction parameters for a sustainable waste-to-resource technology that transcends conventional fuel production.
This study demonstrates that fabricating all-bamboo paper with a multiscale network of untreated bamboo fibers and mechanically prepared microfibrillated cellulose yields high-strength materials capable of replacing plastic in durable packaging boxes that withstand significant impact without structural failure.
This study compares calcined (CI) and sulfonated calcined (SCI) iron catalysts derived from waste iron filings for cow tallow biodiesel production, finding that while CI offers more consistent yields across varying methanol-to-oil ratios, SCI achieves a higher maximum yield of 62.159% at the optimal 5:1 ratio due to its superior surface area and pore volume.
This study reveals that solvated bromide ions disrupt interfacial proton transfer and reduce surface hydroxide density by altering water orientation at the electrode interface, thereby causing rapid poisoning of the oxygen evolution reaction on Ni-based catalysts in alkaline media.
This study demonstrates the green synthesis of Mn-doped ZnO nanoparticles using *Bos indicus* cow dung extract, which exhibit enhanced antibacterial activity against specific bacteria and improved selective cytotoxicity against MCF-7 breast cancer cells compared to pure ZnO.
This study develops and validates a simplified Surface Model for the Ni(OH)₂/NiOOH reaction on a nickel rotating disk electrode, demonstrating that composition-dependent activity coefficients are the dominant factor in accurately simulating cyclic voltammetry and establishing a robust foundation for modeling organic electrooxidation.
This study demonstrates that blending multiwalled carbon nanotubes (MWCNTs) and polytetrafluoroethylene (PTFE) as additives in jatropha oil significantly enhances friction reduction and anti-wear performance under steel-steel contact compared to using the base oil or individual additives alone.
This mini-review synthesizes recent advances in the direct aqueous carbonation of calcium carbide residue (CCR) and ferrous slag, highlighting how their combination overcomes individual passivation and kinetic barriers to enable CO₂ sequestration while evaluating the resulting products' potential as supplementary cementitious materials and identifying durability verification as a critical research priority.
This study demonstrates that ultrasound-assisted extraction (UAE) is particularly effective for recovering high phenolic content and antioxidant activity from yellow onion peels, while the optimal green extraction method for antimicrobial activity depends on both the onion variety (red or yellow) and the target bacterial type.
