Utilization of subsoil as a growing medium for the nursery is a challenge to replace the role of topsoil as media for oil palm nurseries mainly on main nursery. This research was aimed at studying the effects of organic Guano and inorganic NPK…
The inclusion of metals/alloys inside the pores of zeolite is of a great interest for developing composites with functional materials distributed in the intended fields. Zirconium-containing NaY5.7 zeolite samples with 1 wt% and 3 wt% metal loading…
One of the most promising materials for storing hydrogen in solid state would be included in metal-carbon composites. In order to obtain nanocrystalline metal particles encapsulated by crystalline or amorphous carbon, mechanosynthesis of…
Production of composites was done by mixing the filler and matrix. The common matrix used to produce composite is plastic ore with types of poly propylene, poly ethylene and others. To know the characteristics of composite boards made from recycled…
