3. Síntese de derivados do fulereno-C60
Presently, C60 fullerene and its derivatives are of great importance in chemistry, mainly due to their physical properties and biological activities. One of the main problems related to C60 is its low solubility in the commonly used solvents, which limits its application. Aiming to study their physicochemical properties, 17 new C60 derivatives with appropria

8. Propriedades e aplicações recentes das ciclodextrinas
Cyclodextrins (CDs) are cyclic oligosaccharides comprised of six or more glucose units connected by alpha-1,4 bonds. They have hydrophobic cavities with a hydrophilic exterior, and are versatile receptors for a variety of substrates. This ability allows them to be applied in many fields, as distinct as supramolecular chemistry, nanotechnology, pharmaceutical
