A stable colloidal suspension of nanostructured lipid carriers (NLCs) was synthesized from natural source of lipid. The toxicity and insolubility of drugs in water remain a significant problem and has led to the development of food-grade drug delivery systems such as nanostructured lipid carriers (NLCs). NLCs composing various amount of beeswax (BW), rosemary oil (RO) and poloxamer 188 (P188) were prepared by melt-emulsification combined with ultrasonication method. The physicochemical properties of NLC also were determined. Optimization of the formulation (F) was performed based on the criteria of stability. Formulation with the smallest particle size and highest magnitude of zeta potential …

New Ag(I) and Au(I) mixed ligand complexes were synthesised using thiosemicarbazone and phosphine in search of a new biologically active compounds. CHN elemental analysis, powder X-ray diffraction (PXRD), single crystal X-ray diffraction as well as several spectroscopic techniques such as FT-IR, Energy-dispersive X-ray (EDX), 1H, 13C, and 31P{1H} NMR were performed to elucidate the structure of these complexes. Elemental analysis suggested that the stoichiometry of the complexes formed by the reaction of Ag nitrate with thiosemicarbazone in the presence of phosphine was indeed 1:2:1 molar ratio, while for the Au to be in 1:1:1 molar ratio. The Ag and Au …
