• Abstract

  Lignin derivatives, obtained from Black liqueur, will be used to prepare columns for adsorption of heavy metals from solutions of our under graduation laboratories. Due the polymeric characteristics of this material, which presents superficial functionalities such as phenol and carboxylic groups, it also will be used to produce chemically modified electrodes beyond active carbon. The last…

• Abstract

  Chagas' disease is endemic for most of Latin America, serioulsy affectinq the health of infected people and shortening their lives. Around 16 to 18 million people are estimated to be infected and about 50 thousands of deaths are registered each year in the 21 endemic countries. The therapeutic armamentarium against the parasitosis is scarce, as only two drugs have been used, none of them …

• Abstract

  Inflammatory processes are present in neurodegenerative diseases such as Alzheimer's disease , cancer and autoimmune diseases whose treatment is the administration of non-steroidal antiinflammatories and flavonoids to the patient. The project aims to characterize the electrochemical behavior of active and potentially bioavailable flavonoids , and their action as inhibitors of the enzyme C…

• Abstract

  The negligible diseases (Chagas, Leishmaniasis and Malaria) still represent nowadays a major public health problem. The biological activity of the compounds with antichagasic properties is closely related to the free radicals action, which are derivative from the monoeletronic reduction of nitro groups in the heterocyclic compounds. The electrochemical behavior of three new compounds with…

• Abstract

  This project will consist of Synthesis, characterization and applications of nanoporous silicas and ordered carbon reply, obtained from the nanocasting strategy using lignin as modifying agent and source of carbon. SBA-15 and FDU-1 materials, with hexagonal and cubic structures, respectively, will be synthesized in acid medium, using tetraethylorthosilicate (TEOS) as silica source and, P-…
