We report on the synthesis and characterization of a novel cobalt trimesate metal-organic framework, designated as KCL-102. Powder X-ray diffraction pattern KCL-102 is dominated by reflection at 10.2° (d-spacing = 8.7 Å), while diffuse reflectance UV-Vis spectroscopy indicates that divalent centers are in two different coordination geometries: tetrahedral octahedral. Further, material shows low...

Rice requires nitrogen for the growth of plant vegetative organs. Potassium plays a role in regulating osmotic pressure and turgor plants, especially dry land. The purpose this study was to determine effect varieties potassium fertilization on yield upland rice. research conducted Bleberan Village, Kab.
