Item type:Publication, Growth Responses and Regression Analysis of Zinc Oxide Nanoparticles in Indica Rice (Oryza sativa L.)(2022-01-01); The use of metal nanomaterials to promote plant growth and inhibit plant pathogenic microorganisms is gaining interest. In this study, zinc oxide nanoparticles (ZnONPs) were evaluated for effects on growth and productivity of indica rice plants (Oryza sativa L.). The rice plant was exposed to ZnONPs with different concentrations i. e. 0, 200, 600 and 800 mg/l. The plant height, weight and the number of panicles per clump were investigated. The result showed that 200 mg/l of ZnONPs induced the highest enhancement of plant height, weight and the number of panicles per clump with a significant difference compared to other groups. The mathematical model of the height, weight and the number of panicles per clump was analyzed by linear regression, and the determination coefficient (R<sup>2</sup>) of the linear regression model was 0.86, 0.84 and 0.52, respectively. This linear regression model could be potentially extended to the indica rice plant cultivation process in practical applications to predict the rice plant growth and productivity in commercial cultivation. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Characterization and proximate analysis of composite biochar briquette from oil palm frond and red clay(2025-01-01); Sutjaritvorakul, ThanawatThe ultimate goal of this research is to create effective and environmentally friendly biochar briquettes from oil palm frond (OPF) waste. Red clay, a plentiful local resource, has been demonstrated to improve the properties of fuel briquettes. In this study, the tested composite briquettes (biochar:red clay:starch by weight) were prepared in the following ratios: 40:55:5 (T2), 50:45:5 (T3), 60:35:5 (T4), and 70:25:5 (T5), while the control sample (T1) consisted of 95:5 (biochar:starch). All of the different ratios were analyzed using proximate analysis. The results showed moisture content ranging from 7.35% to 8.47%, ash content from 29.75% to 49.82%, volatile matter from 15.63% to 17.47%, and fixed carbon from 25.31% to 46.48%. Among them, T4 exhibited the lowest moisture and ash content and the highest calorific value at 5,650 cal/g, making it the optimal candidate for further investigation. A comprehensive analysis of T4 was conducted using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The techniques revealed the morphological structure and inorganic components that contribute to the energy efficiency of T4. The study also examined air pollutant emissions. T4 produced lower emissions of pollutants such as carbon monoxide (CO), carbon dioxide (CO<inf>2),</inf> total volatile organic compounds (TVOCs), formaldehyde (HCHO), and particulate matter (PM<inf>1.0</inf> and PM<inf>2.5</inf>) compared to the OPF biochar briquette without red clay (T1). Composite biochar briquettes made from OPF and red clay (T4) are safe and suitable for use as a fuel source for household applications like cooking and heating. This research contributes to the development of the green bioeconomy and supports sustainable energy initiatives. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Process Optimization and Kinetics Study of Metals Leaching from Spent Hydrocracking Catalysts by Cell-free Medium Filtrate of Aspergillus aculeatus(2026-10-01); Sutjaritvorakul, ThanawatHydrocracking catalysts (HCC) are widely used in petrochemical refinery catalytic processes. Although these catalysts are frequently reusable, the efficacy of HCC gradually declines. This procedure leads to the production of a large amount of spent hydrocracking catalyst (SHCC), which contains valuable metals as well as hazardous chemical wastes. The pyro-hydro-metallurgical approach for metal restoration from catalyst waste is insufficient for environmental sustainability. The application of biological techniques is a more environmentally friendly strategy. Fungal leaching has emerged as an alternative method for the recovery of metals. Although metal recoveries were moderate, the use of cell-free fungal filtrate enabled rapid leaching under mild conditions, highlighting its potential as a greener and operationally simpler alternative to conventional whole-cell bioleaching. Aspergillus aculeatus was isolated from contaminated soil of a gold mine located in Thailand. The filtrate of the fungal culture medium was utilized for metal leaching, and this experiment was carried out using a Box-Behnken experimental design. The optimum processes included a spent catalyst density of 10% (w/v), a temperature of 50 °C, and a shaking rate of 148 rpm for 180 min, with the catalyst powder size being less than 150 µm. The predicted highest metal recovery rates of 7.98% for Al, 5.27% for Ni, 24.55% for Mo, 11.92% for Fe, and 0.93% for Zn aligned precisely with the actual experimental results. The comprehension of kinetics through the application of the shrink core model indicates that the mechanism of reactions is predominantly influenced by the surface chemical control reaction rather than the diffusion process. The leaching rates of Mo, Fe, Al, Ni, and Zn followed a descending order from highest to lowest. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, MYCO-MEDIATED SYNTHESIS AND α-GLUCOSIDASE INHIBITORY ACTIVITY OF SILVER NANOPARTICLES PRODUCED BY XYLARIACEOUS FUNGI(2023-01-01); Metal nanomaterials could be applied in various fields and could be synthesized via living organisms such as plants, bacteria and fungi. Here, the ability of Xylaria sp.5 to produce silver nanoparticles (AgNPs) and α-glucosidase inhibitory activities by the AgNPs produced by Xylaria sp.5 were investigated. The culture broth of Xylaria sp.5 was used to synthesize AgNPs by using 0.1 M of silver nitrate (AgNO3) solutions. The mycogenic crystals were investigated for the morphological characteristics and chemical composition by scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDS), Fourier-transform infrared spectroscopy (FTIR) and X-ray powder diffraction (XRD). The results showed that AgNPs were successfully produced. Moreover, AgNPs were tested for α-glucosidase inhibitory activities. The crude enzyme derived from rat intestine consisted of maltase and sucrase. The percentage of inhibition at 50 mg/ml of maltase and sucrase was 63.21 ± 0.67 and 54.42 ± 0.11, respectively. This study demonstrated that the supernatant culture broth of Xylaria sp.5 can be used to synthesize AgNPs which possess α-glucosidase inhibitory activities. Collectively, this method could be a promising alternative for low cost and non-polluting production of AgNPs which could be potentially utilized for the treatment of type 2 diabetes mellitus. - Some of the metrics are blocked by yourconsent settings
