Influência da laminação assimétrica nas propriedades mecânicas do alumínio AA 1050
(Universidade Federal de São Carlos, 2017-04-27)
Aluminum sheets are produced by rolling followed by annealing. However when submitted to deep drawing earing appears, caused by the plastic anisotropy resulting from the production process. After annealing the main texture ...
Modificação da molhabilidade da celulose por processos subsequentes de ablação e deposição a plasma
(Universidade Federal de São Carlos, 2017-03-14)
Cellulose is a biopolymer available in abundance in nature, which presents very interesting properties mainly for the textile, packaging and paper industry. However, due to its strongly hydrophilic character, resulting ...
Utilização de resíduos de poliuretano expandido na moldagem por injeção de compósito de matriz de polietileno de alta densidade
(Universidade Federal de São Carlos, 2017-04-03)
For a few years now polymeric materials have been ever present around the whole globe. Polyurethane (PU) for example is the sixth most produced polymer globally, generating with that a considerable amount of scrap due to ...
Desenvolvimento de um biossensor amperométrico baseado em uricase oxidase associado com nanopartículas de platina para detecção de ácido úrico
(Universidade Federal de São Carlos, 2017-03-28)
Uric acid is an endogenous substance produced from the metabolism of purines. The concentration of serum uric acid in the human body considered normal is between 0.24 - 0.52 mmol.L-1 . High levels of uric acid in the body ...
