The aim of the present work was the study of the viability of a manufacturing route of parts with the Cu-based Shape Memory Alloy (SMA) Cu- 11,3Al-3,2Ni-3Mn-0,5Zr through gas atomization followed by Selective Laser Melting ...
Investigação do desenvolvimento microestrutural de eletrólito sólido β/β’’-alumina visando sua utilização em bateria ZEBRA
(Universidade Federal de São Carlos, 2014-10-09)
The ZEBRA battery (Zero Emission Battery Research Activity) is an efficient electrochemical energy storage device with high energy density and high power. This has been considered one of the key technologies for insertion ...
Preparação de nanocompósitos baseados na intercalação de argilominerais em matrizes ureia-formaldeído para aplicação como fertilizantes de liberação controlada
(Universidade Federal de São Carlos, 2014-02-27)
The increase on the price of fertilizers, and the high Brazilian importing
dependency of this material, raise the cost of cultures. Such cost may be
reduced by more efficient and efficiently used fertilizers. From an ...
Aplicação do método biomimético para o recobrimento da liga AZ91 com apatitas para aumento da resistência à corrosão
(Universidade Federal de São Carlos, 2015-08-28)
In orthopedic medicine and traumatology, the use of implants to help bone reconstitution is very common. They are divided in two groups: Internal and external fixation devices. After bone reconstitution, these components ...
