The natural compounds of boron have many applications, primarily as a dietary supplement. research is based on the discovery that diester chlorogenoborate complex can be detected and quantified from green coffee beans. study reports such molecule also synthesized in stable form via direct reaction boric acid chlorogenic mixture acetonitrile–water (1:1, v/v) left to evaporate over period 48 h at...

OBJECTIVE The purpose of this study was to analyze clinic and radiologic features of the 69 odontoma cases and present a rare case of erupted compound odontoma in the oral cavity. MATERIAL AND METHODS The 69 cases were analyzed with regard to the following parameters: age, gender, location, associated unerupted teeth, missing teeth, radiological and histopathological features and treatment pr...

introduction: developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. in this work, sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. methods: sm-153 chloride was obtained by thermal neutron flu...

A symmetric complex [NiL2(H2O)2]Cl2, where L = 2-picolylamine was synthesized and characterized by spectroscopic and structural methods. Single crystal X-ray studies reveal that the Ni(II) center located in a pseudo-octahedral N4O2 environment with bidentate ligands L positioned in basal and two water molecules in the apical position. The complex is solvatochromic, ionochromic and thermochromic...

The synthesis and single-crystal X-ray structure determination of the title compound (phen)Pb(02CMe) is described. The complex crystallizes in the monoclinic space group P2 /c, a = 7.823(3), b = 12.421(4), c = 9.262(2) ?, ? = 79.92(3)", Z = 4, yielding R 0.048 for 3210 independent reflections. The coordination number around the lead atom is six. [Pb-N 2.54(2), 2.56(4)],[Pb-0, 2.19-2.22]
