Estudos de separação de lignina do licor negro kraft em diferentes condições experimentais: caracterização e fracionamento
(Universidade Federal de São Carlos, 2016-04-19)
The processes of separation and isolation of Kraft lignin obtained have been insufficiently resear ched, since much of the lignin of liqueurs obtained industrially is burned for energy recovery ...
Desenvolvimento de biossensor amperométrico baseado em monoamina oxidase-b para detecção de neurotransmissores
(Universidade Federal de São Carlos, 2015-02-27)
This work focuses on the production of nanostructured films of poly (ethyleneimine) PEI together with MAO-b free and encapsulated in liposomes constructed by the layer-bylayer technique (LbL), for application in biosensors. ...

(Universidade Federal de São Carlos, 2017-03-13)
In a technology-driven society, the increase of electrical and electronic equipment consumption has been a matter of concern in relation to its management, since the expectation is that the quantity of electrical and ...
Obtenção de nanocelulose via hidrólise ácida a partir dos resíduos da produção de cerveja
(Universidade Federal de São Carlos, 2016-04-01)
The industrial waste usage for technological application has been gaining ground in different segments and applications. One of the prominent sectors is Material technology, where these residues can be used to obtain the ...
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 ...
