New magnetic Mn3O4/g-C3N4 and Ag2MnO4/g-C3N4 nanocomposites have been synthesized based on Mn(II) Schiff base complex and used for sonodegradation of methylene blue (MB) and methyl orange (MO) dyes in aqueous solution. Ag2MnO4 nanoparticles (NPs) have been synthesized from Mn3O4 NPs and AgNO3 under ultrasonic irradiation for the first time. The results indicate that the sonodegradation method of dyes in the presence of Mn3O4/g-C3N4 and Ag2MnO4/g-C3N4 nanocomposites is better than solar degradation processes. The better photodegradation rates for MB and MO dyes observed in the presence of Ag2MnO4/g-C3N4 (k= 0.0916 min-1) and Mn3O4/g-C3N4 (k= 0.0381 min-1), as compared to pure Mn3O4 and Ag2MnO4 compounds The synthesized nanocomposites are good fluorescent materials.

PPMANC1 and PMMANC2 nanocomposites have been fabricated using two reactive clays by two methods and characterized in order to estimate the impact of the different dispersion states on the mechanical properties. A simple and economical process of polymerisation is adopted to develop PMMANC nanocomposites using an Algerian clay, trying to optimize the distribution of PMMA in the clay layers. Two distinct types of organic clays have been mined, labelled as (i) benzyltrimethyl ammonium chloride (BTBA-Mag (1CEC)) and (ii) hexadecyltrimethylammonium bromide (HDTAB-MagCTA (2.5CEC)). Evaluation of the properties of the PMMANC1 and PMMANC2 nanocomposites are carried out using different physicochemical techniques. The results obtained by XRD, transmission electron microscopy reveal that the modified maghnite are well dispersed in the matrix and significant improvements in thermal properties are observed from thermal analysis. The Young module, impact resistance and tensile strength of the nanocomposites incorporating 5% organoargile are the most effective compared to the two synthesis processes.

Mucilage is a natural polysaccharide with a variety of physicochemical and structural properties. Plant-derived mucilage has a wide range of applications, such as binding agent, stabilizer, emulsifying agent, thickening agent, and gelling agent. This study investigated the potential of underutilized cereals’ mucilage and further explored their application by synthesizing mucilage-based hydrogels. For this purpose, we have explored four new sources of mucilage, namely adzuki beans (A b ), amaranth (A m ), proso millet (P r ), and little millet (L m ). The underutilized cereals’ mucilage application has been examined by developing hydrogels through the free radical co-polymerization technique. Mucilages are confirmed to be a natural thickening and a substitute for synthetic polymers after being evaluated physically and phytochemically. Structural analysis of mucilages and their hydrogels (A b H, A m H, P r H & L m H) were characterized by using FTIR-ATR, XRD, 1 H & 13 C NMR techniques. It confirms that all four mucilages are rich in polysaccharide residues and grafting of sodium acrylate has been successfully done on mucilages. Thermal gravimetric analyses represent the better thermal stability of the synthesized hydrogels than their respective mucilages. SEM confirms the porous structure of the mucilages and their hydrogels. All of these studies demonstrated that the underutilized mucilage from cereals might be a good feedstock for a hydrogel-forming agent, which can be explored in the food, cosmetics, and pharmaceutical industries.
粘液是一种天然多糖，具有多种物理化学和结构特性。植物源性粘液具有广泛的用途，如粘合剂、稳定剂、乳化剂、增稠剂、胶凝剂等。本研究探讨了未充分利用的谷物粘液的潜力，并通过合成粘液基水凝胶进一步探索其应用。为此，我们探索了四种新的粘液来源，即小豆(A b)、苋菜(A m)、小小米(P r)和小小米(L m)。利用自由基共聚合技术制备水凝胶，考察了未充分利用的谷物的黏液应用。经过物理和植物化学评价，胶浆是一种天然增稠剂和合成聚合物的替代品。采用FTIR-ATR、XRD、1h和13c NMR等技术对胶浆及其水凝胶(A b H、A m H、P r H和L m H)进行结构表征。证实了四种胶浆均含有丰富的多糖残基，并成功地在胶浆上接枝丙烯酸钠。热重分析表明，合成的水凝胶的热稳定性优于它们各自的黏液。扫描电镜证实了黏液及其水凝胶的多孔结构。所有这些研究都表明，未充分利用的谷物粘液可能是水凝胶形成剂的良好原料，可以在食品，化妆品和制药工业中进行探索。
