The Adiwiyata program is a government implemented in 2006 due to Indonesia’s declining environmental quality. As part community, students need be educated about caring for the environment that can grown through education. Much research has been described on program, but information role of developing character still limited. This study aims create innovation care characters elementary schools S...
The search for new materials is a very intense task in many technological areas. In 2015, variant of graphene was proposed, the pentagraphene, which followed by propose pentagonal boron nitride structure called penta-BN2. Based on these structures, we investigated electronic, magnetic, and optical properties penta-BN2 nanoribbons (p-BNNRs) considering four different kinds edges, carefully closi...
Natural myo-inositol phosphate antioxidants containing the 1,2,3-trisphosphate motif bind Fe(3+) in the unstable penta-axial conformation.
The title compound, [Fe4(C10H15)2(C8H10O4S2)2S4], contains a twisted Fe4S4 cubane-like core. A twofold rotation axis passes through the Fe4S4 core, completing the coordination of the four Fe atoms with two penta-methyl-cyclo-penta-dienyl ligands and two chelating dithiol-ate ligands. There are three short Fe-Fe and three long Fe⋯Fe contacts in the Fe4S4 core, suggesting bonding and non-bonding ...
