(Universidade Federal de São Carlos, 2007-12-07)
Enzymatic hydrolyzed proteins present some advantages over the pool of
amino acids obtained after a chemical hydrolysis: lower osmolality (easier absorption by the
organism) and better sensorial characteristics. The removal ...
Propriedades estruturais e eletroquímicas de espinélios de lítio e manganês dopados para uso em baterias de lítio.
(Universidade Federal de São Carlos, 2005-09-01)
The spinels investigated in the present work
were obtained by solid state reaction at 750 ºC for 72 h among the precursors
ε-MnO2, LiOH and the respective oxides/salt of the doping ions. In order to control
the particles ...
