Desenvolvimento de nanocompósitos baseados em hidrogéis aplicados à liberação de nutrientes agrícolas
(Universidade Federal de São Carlos, 2014-03-21)
Nanocomposites were developed based on polyacrylamide hydrogels (PAAm) and methylcellulose (MC) reinforced with montmorillonite (MMT), undergoing the materials to subsequent hydrolysis process and evaluating their loading ...
Estudo teórico computacional dos sistemas micelares de alquilbenzenos em diiodometano
(Universidade Federal de São Carlos, 2014-02-28)
The surfactant-like behavior of the alkylbenzenes in diiodomethane is experimentally verified, being observed, in addition to the characteristic effects on the surface tension, evidences of clusters formation. The main ...
Síntese de porfirinas contendo grupos do tipo uracil fundidos nas posições β-pirrólicas
(Universidade Federal de São Carlos, 2014-07-28)
In this work the synthesis of new porphyrin derivatives were proposed. The preparations of new compounds containing uracil groups at β-pirrolic position were studied based on their interest in organics synthesis. We ...
Estrutura cristalina e eletrônica do CaS: teoria do funcional de densidade aplicada a modelos periódicos
(Universidade Federal de São Carlos, 2014-02-26)
The incessant search for better materials with diverse applications and increasingly smaller size has been performed by numerous research groups. The calcium sulfide semiconductors have been the focus of study for applications ...
Reforma a vapor de acetona sobre catalisadores de Ni e Co/MgAl2O4: efeito das propriedades redox dos reagentes e dos catalisadores nos caminhos de reação
(Universidade Federal de São Carlos, 2014-12-12)
The Steam reforming of Acetone (SRA) reaction was studied on magnesium aluminate (MgAl2O4) supported nickel (Ni) and cobalt (Co) catalysts. The catalysts with 8 wt.% of Ni, Co or Ni-Co were prepared by dry impregnation and ...
