This study aimed to optimize the pelleting and coating process for red clover seeds, addressing issue of low success rates. Through theoretical analysis experimental research, pan fill rate, powder supply quantity, time were identified as key factors influencing rate. Single-factor experiments conducted investigate effects these parameters on quality seed coating. Based results, orthogonal trials carried out, response surface was employed reveal influence patterns interactions each factor. The research results indicate that affecting ranked in order importance, are time, quantity. mathematical model optimization, optimal combination determined be rate 35.9%, quantity 160.2 g, 6.9 s. Under conditions, a 94.3% achieved validation experiments. provides foundation practical guidance optimizing which is significant improving promoting cultivation.

In this work, we introduce a new composite material consisting of Mn(1-x)ZnxFe2O4 (MZF) and wasted coffee grounds carbon (C). Crucially, the surface chemistry ‎composite, which lacks Zn2+ ions in octahedral locations, highlights its distinctive structural ‎characteristics. Before integration composite, saturation magnetisation ‎of sample was recorded as 53.073 emu/g. However, it decreased to 45.49 emu/g ‎after formed reaction processes occurred. UV-spectroscopy ‎enabled measurement band gap energies, showed that energies for ‎ferrite were 2.93 eV MZF/C 2.12 eV. By utilising plasmonic ‎photocatalysis, has shown exceptional effectiveness high-temperature photocatalyst, specifically breakdown methylene blue (MB) Eosin (EO) dyes, ‎which are representative basic acidic respectively. The study demonstrated enhanced photocatalytic degradation kinetics under both visible light sunlight, with sunlight showing superior performance. Over 120-min period, ferrite achieved removal efficiency 89% compared 68% artificial light. photocatalysis principles, work clarifies optical ‎properties emphasises capacity tackle environmental ‎issues through effective dye mechanisms.‎
