introduction: widespread medical usage of botulinum toxins has increased the need for the precise analysis of its biological activity. the aim of this study was production and crystallization of the botulinum type a toxins. methods: in this study, clostridium botulinum was grown and inoculated into the tripticase soya broth culture media, under anaerobic condition and toxin production was monit...

The results of synthesizing a novel tridentate Schiff-base ligand and its metal complexes have been given. itself is described as being tridentate. synthesis the has following chemical formula: (E)-2-((2S)-4-(tert-butyl) -2-((S)-(phenylamino) (p-tolyl) methyl) cyclohexylidene) hydrazine -1-carboxamide was produced byproduct reaction between benzoic acid (((4-(tert-butyl)-2-((S)-(phenylamino)(p-...

The synthesis of magnetic nano-sized spinel ferrites has become an important area research, due to their several potential applications. In this work, CoFe2O4 nanoparticles were synthesized by the co-precipitation method. Structural, magnetic, and photocatalytic properties cobalt analyzed based on chemical composition considering biological properties. Structural morphological investigated X-ra...
