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。

Highly substituted pyrazoles have been prepared by condensing 1,3-diketones and various hydrazine derivatives using silica-phosphoric acid nanoparticles (nano-SPA). This nano solid catalyst has been prepared by the reaction of nano silica chloride with dry phosphoric acid. This green methodology has advantages such as short reaction times, simple work-up, high efficiency, reusability of the catalyst and no use of any solvents.

In this work, thermal and catalytic pyrolysis of waste expanded polystyrene (WEPS) have been investigated in a laboratory designed semi-batch reactor in the temperature range of 400-700℃ and heating rate of 15 ℃/min to produce gasoline range lower paraffins and valuable aromatics i.e., benzene, toluene and ethylbenzene (BTE). Three different type of reactor arrangements i.e., liquid phase/A-type, vapour phase/B-type and multiphase/AB-type have been used to conduct the catalytic pyrolysis of WEPS using nickel on silica-alumina catalyst. The thermal pyrolysis of WEPS produced highest liquid yield of 94.37 wt.% at a temperature of 650℃ and heating rate of 15 ℃/min, whereas, liquid phase/A-type, vapour phase/B-type and multiphase/AB-type catalytic pyrolysis produced highest liquid yield of 88.54 wt.%, 83.21 wt.%, and 81.15 wt.%, respectively, at the same heating rate of 15 o C/min and at the temperature of 600℃, 550℃, and 550℃, respectively. The pyrolysis oil obtained from thermal pyrolysis mainly contains styrene monomer of 84.74 wt.% and very less BTE content of 11.38 wt.%. Among, the all types of catalytic pyrolysis, AB-type/multiphase pyrolysis produced pyrolysis oil with highest amount of BTE content of 28.56 wt.%. Furthermore, the pyrolysis oil obtained from A-type, B-type and AB-type catalytic pyrolysis contains low styrene content of 69.94 wt.%, 65.67 wt.% and 55.55 wt.%, respectively, as compared to thermal pyrolysis (84.74 wt.%).
