Cellulose nanomaterials isolated via enzymatic and mechanical routes for application in hydrogels
(Universidade Federal de São Carlos, 2021-11-10)
The integrated production of different bioproducts has been considered essential to make biorefineries economically viable. Among the bioproducts, cellulose nanomaterials (CNs) have attracted significant attention due to ...
Estudo de catalisadores bimetálicos de platina ou paládio e cobre suportados em céria para a reação de PROX-CO
(Universidade Federal de São Carlos, 2016-10-13)
In the present work, catalysts were prepared xCuO / CeO2 (x = 1.0 and 3.0% by mass)
doped with Pt or Pd for application in the preferred oxidation reaction of carbon
monoxide, also known as PROX-CO reaction. The catalysts, ...
Modelagem e otimização da cromatografia de troca aniônica no processo de produção de proteína de pneumococo
(Universidade Federal de São Carlos, 2019-12-12)
Pneumococcus surface protein A (PspA) is a lactoferrin-binding protein that can be found on the surface of Streptococcus pneumoniae. The use of this protein as a carrier in the formulation of conjugate vaccines contributes ...
Catalisadores de CuO/CeO2 promovidos com Au e Pt - estudo do impacto da interface e das propriedades eletrônicas do Cu no desempenho catalítico na reação de CO-PROX
(Universidade Federal de São Carlos, 2020-05-06)
The copper-ceria system has been extensively investigated to be used as a catalyst in the preferential oxidation of CO reaction (CO-PROX), aiming the purification of H2 streams from reformed fuels, due to its oxygen storage ...
