The fruits of the species studied from the Plateaux des cataractes were purchased in Brazzaville, specifically at the Plateau des 15 ans and PK markets. Drying was carried out at temperatures of 40, 70 and 105°C in a Memmert brand UN30 oven. Mass measurements were taken every 30 minutes for several hours until the moisture content was almost constant. The modeling of the drying kinetics of citrus seeds was carried out by the Origin Pro 2018 software while following seven models, namely: the models Diffusional, Modified Page I, Lewis, Henderson and Pabis, Page, Avhad and Marchetti, Peleg. The observations of this study on the drying kinetics of seeds highlighted two distinct phases: a rapid temperature increase phase and a gradual decrease phase. Temperature impacted the drying kinetics. As the temperature increases, the drying period decreases. Between 40 and 70 °C, bitter orange seeds are the first to dry out, followed by pomelo seeds, and finally mandarin and orange seeds. For each of the temperatures examined, the Avhad and Marchetti model was the most appropriate to represent the experimental drying data of the different citrus seed species studied.]]> Eliane Thérèse Biassala, Célestine Kiminou Ngounga, Bob Wilfrid Loumouamou, Judelvie Léovic Matimbou, Jean-Mathurin Nzikou, Thomas Silou 2025-01-15 Science and Education Publishing 2025-01-15 1 10 1 7 10.12691/ces-10-1-1 http://pubs.sciepub.com/ces/10/1/2 Anethum graveolens. This study evaluates the inhibitory effect of essential oil extracted from the seeds of this plant on the corrosion of C38 steel in 1M HCl medium. The essential oil was extracted from seeds using a Clevenger apparatus, achieving an average yield of 3.5% via hydrodistillation. Characterization by chromatography (GC/FID and GC/MS) identified 12 constituents representing 98% of the oil's global composition, with carvone (43.5%), dillapiol (26.7%), and limonene (15.4%) being the main components. Gravimetric tests revealed a remarkable inhibitory effect on steel corrosion, with increased concentration and temperature achieving an inhibition efficiency of 82.54% at 0.5 g/L and 338 K. Thermodynamic parameters determined show that the inhibitor's adsorption on the metallic surface follows the Langmuir model. The results indicate a mixed adsorption behavior of this essential oil. DFT calculations correlate the inhibitory activity with the electronic properties of the main constituents of the essential oil.]]> Malick Bathily, Khaly Cissé, Baba Ngom, Mohamed Znini, Diadioly Gassama 2025-08-01 Science and Education Publishing 2025-08-01 1 10 8 17 10.12691/ces-10-1-2
