Abstract: This study reports on the synthesis, characterization, and water release kinetics of a sample of deliquescent acrylamide hydrogel imbibed in activated carbon powder using thermal analysis and FT-IR spectroscopy. It was synthesized by the radical polymerization of acrylamide and N, N'-methylene-bis-acrylamide in the presence of potassium persulfate, calcium chloride, and activated carbon powder. The kinetics of water desorption were evaluated with a pseudo-single component model applied to the isoconversional method using thermogravimetric analysis (TGA) thermograms at heating........

Abstract: Résumé : La ville de Tahoua a connu ces dernières années une augmentation démographique et une expansion urbaine importantes, et donc certaines zones urbaines ou péri-urbaines ne sont toujours pas raccordées au réseau. Pour leurs besoins quotidiens, les habitants de ces quartiers s'approvisionnent à des puits ou des forages, qui peuvent être contaminés. A cela s'ajoute un certain nombre des compagnies ou des particuliers qui conditionnent les eaux des forages en sachets avant leur mise........

Abstract: The widespread use of plastic has led to the pervasive presence of microplastics or plastic particles ranging from 1 to 5 mm in various environments such as freshwater, agricultural soil, and oceans. A significant portion of plastic waste comprises these microplastic fragments, posing emerging threats to ecosystems. Urgent action and comprehensive analysis are essential to track and understand the distribution of microplastics in the environment. Due to their polymeric nature, irregular morphology, and minuscule dimensions, quantifying microplastics presents significant challenges. This review delves into various analytical techniques employed for microplastic assessment, encompassing Fourier transform infrared spectroscopy, Raman spectroscopy, laser diffraction particle analysis, thermal........

Abstract: A series of novel coumarin hybrids (compounds 6a–j) was synthesized using piperidine and its acetamide derivatives. The chemical structures of the newly developed products were elucidated through FTIR, 1H NMR, 13C NMR spectroscopy, and mass spectrometry techniques. Evaluation of the synthesized compounds for antibacterial, antifungal, and antioxidant activities was carried out using ampicillin, Nystatin, and Ascorbic acid as reference standards. The compounds exhibited noteworthy activity against the tested microorganisms, ranging from good to moderate......

Abstract: The development of industrial activity, subject to rapid growth in recent years, has successfully met multiple societal needs while making products and services more accessible to the population. However, the high use of raw materials, consumption of substantial amounts of energy, and the generation of byproducts, waste, and pollutants have created significant imbalances in the economy and the environment. In response to these negative changes, the circular economy emerges as an imperative need in the production of goods and services. Therefore, it is important to identify processes that utilize both waste and byproducts from other industrial processes, allowing the integration.....
