Produção e caracterização de mantas de nanofibras poliméricas eletrofiadas contendo proantocianidinas e sua potencial aplicação no tratamento de lesões cutâneas
(Universidade Federal de São Carlos, 2018-11-23)
The development of novel biodegradable and biocompatible nanofibrous membranes are highly desirable for biomedical applications, including drug delivery and wound dressing. Thus, the present thesis focused on the development ...
Desenvolvimento de procedimentos para a síntese e caracterização de catalisadores e de biodiesel
(Universidade Federal de São Carlos, 2017-06-08)
ABO3 basic catalysts were synthesized by the nitrate-b-alanine solution combustion method. The catalysts powders were produced by self-combustion in times up to 5 min, presenting high crystallinity and single-phase, without ...
Estratégias para a determinação de minoxidil
(Universidade Federal de São Carlos, 2005-07-25)
Methods for the determination of minoxidil in commercial samples are presented. The minoxidil is a pharmaceutical whose dilation blood vessel property is used in the treatment of the Arterial Hypertension and in the treatment ...
Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
