Synthesis, structure and spectroscopic characterization of Ni(II), Co(II), Cu(II) and Zn(II) complexes with saccharinate and pyrazole
Four mononuclear mixed-ligand complexes of Co(II), Ni(II), Cu(II) and Zn(II), with saccharin (sac) and pyrazole (Hpz) were synthesized and characterized on the basis of elemental analysis, FT-IR spectroscopy, magnetic ...
Microwave assisted synthesis: A Mn/Ni reaction system affording Mn5Ni4, Mn2Ni2 and Mn7 complexes
Following our interest in microwave assisted synthesis in coordination chemistry; we report here the results of the study of a mixed metal Mn/Ni system under common bench-top conditions and using the microwave reactor. ...

Structural Characterization of Chitosan Modified Vesicles
Caracterização estrutural de vesículas modificadas com quitosana
Vesículas a base de L-α-fosfatidilcolina (PC) y mezclas de PC/fosfogliceroles fueron caracterizadas por medio de dispersión de luz dinámica (DLS), microscopía electrónica de barrido-criogénico (Cryo-SEM) y calorimetría de ...
Influence of nanosilica and diatomite on the physicochemical and mechanical properties of binder at unaged and oxidized conditions
Modification of binders helps address common distresses in pavements by changing their essential properties. In order to further characterize the role of additives in these changes, a set of nanosilica and diatomite modified ...
