Binary oxides with defined hierarchy of pores in the esterification of glycerol
Alves, Nuryana Ferreira; Santiago Neto, Antonio de Brito; Bessa, Bruno dos Santos; Oliveira, Alcemira Conceição; Mendes Filho, JosuéVarious porous binary oxides with elevated textural properties were obtained in this work. The as-synthesized solids were calcined or modified by reflux and extraction processes. Characterizations through SEM, nitrogen physisorption and TEM techniques demonstrated the formation of porous metal oxide networks over all solids. XRD, thermal analyses and FTIR measurements showed the existence of nanosized rutile Ti...

Oliveira, Alcemira ConceiçãoThis study deals with strategies for rational designing of multicomponent solids emtricitabine, and a salt ondansetron hydrochloride based on crystal engineering and polymorphism of efavirenz. The efavienz is a Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTI) with low solubility. In this case, it was investigated the influence of the preparation method of efavirenz (Form I) using a solvent-assisted milli...
