Abstract: The use of contaminated drinking water by some villagers results in the spread of waterborne diseases such as diarrhea, cholera, and other long-term illnesses. This present study aims to produce ceramic water filter pot blend biomass as an alternative water purifier for rural areas. Clay and bimass samples were obtained from Kaura Namoda Zamfara. The physical properties of clay, namely moisture content (10.54%), specific gravity (1.74%), dry density (1.61%), liquid limit (32.84%), and shrinkage (12.70%), and proximate analysis of the biomass were determined using standard analytical methods.......

Abstract: Hybrid polymer is formed by Combining two distinct polymers. The resulting polymer has properties of both components that were not achievable in a polymer alone. By reacting with another substance, one resin can improve certain of its properties without sacrificing the original resin's qualities. For adhesives, sealants, and coatings, silylated polyester and polyether hybrids are essential to the industry. They are low toxic compared to solvent-based goods, silicones, and polyurethanes. The synthesis, characteristics, and uses of these silylated hybrid system are thus covered in a large body of literature........

Abstract: The synthesis of a novel nanoparticle Co3BaNiO6, utilizing co-precipitation method is carried under controlled conditions. Structural and morphological properties of the as synthesized material are meticulously characterized through X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) etc. techniques. Furthermore, we investigated the impact of calcination temperature on the morphology of the nanomaterial. UV–Vis spectroscopy revealed a peak absorbance at 232nm, with an optical bandgap estimated to be ≈4.3eV.Subsequently, the synthesized nanoparticles (NPs) are then employed as catalyst for the photodegradation.......
