Effect of Cassava Starch and Tree Gum Binders on the Physical Properties of Onion Leaves Briquettes

Onion leaves can be seen lying as a waste which also littered houses, markets, walk ways, and gardens of the study area. Briquetting of onion leaves is relatively new. The effect of a binder on the physical properties of onion leaves briquettes using two different binders of Cassava Starch and Tree Gum was studied. Three of each sample was produced with a different binder to briquettes ratio of 90:10, 85:15, and 80:20 using a manual press briquetting machine. The result of a water resistance measurement shows that all the sample of briquettes produced can resist water for more than 3 minutes, the result of compressed density, dimensional stability, relaxation ratio shows that samples binded with tree gum has the highest value compare to the samples binded with cassava starch. Based on the results obtained, it can be concluded that the briquette from onion leaves with cassava starch as binders can be used as a substitute for biogas

Review on Y-type hexaferrite: Synthesis, characterization and properties

Ferromagnetic properties of hexaferrites induce magnetisation inside their crystal structure, separating them into uniaxial and ferroxplana hexaferrites. Y-type is the first observed ferroxplana ferrite with spontaneous magnetization in the basal c-plane perpendicular to the c-axis. Y-type is a material class that exhibits a more comprehensive range of adjustable characteristics. This article provides a comprehensive overview of the synthesis methods to produce Y-type hexaferrite (A2Me2Fe12O22, where A can be Ba or Sr and Me is any divalent metal ion) and techniques used to characterize its properties. Due to the potential applications of Y-type hexaferrites, numerous authors synthesized several kinds of Y-type hexaferrite using a variety of metal substitutions for Me, Fe, and A. Most research on Y-type hexaferrite has concentrated on its structural and magnetic characteristics to investigate magnetoelectric and microwave (MW) device applications. In this review, we reported the suitability of Y-type hexaferrite for multiple applications in current information and communication processing equipment according to the previous findings
