Seletividade da Clinoptilolita natural por metais tóxicos em sistemas aquosos.
(Universidade Federal de São Carlos, 2004-12-13)
Natural zeolites are the most important inorganic cationic exchangers exhibiting high
ion exchange capacity, selectivity and environment compatibility.
Heavy metals are well known for toxicity and their disposal is a ...
Secagem convectiva de folhas visando a obtenção de compostos bioativos via extração supercrítica
(Universidade Federal de São Carlos, 2019-04-11)
In this work, an investigation through experimentation and mathematical modeling was carried out with the intention of evaluating the drying process of pitangueira (Eugenia uniflora L.) and olive tree (Olea europaea L.) ...
Análise do desempenho de meios filtrantes na filtração de nanopartículas durante o aumento de sua queda de pressão
(Universidade Federal de São Carlos, 2019-02-27)
The performance of filter media in filtration is the main factor in choosing a material that meets the requirements for a filtration process. It takes into consideration the collection efficiency, permeability, pressure ...
Desenvolvimento e avaliação de meios filtrantes com nanofibras eletrofiadas e agentes bactericidas aplicados na filtração de ar
(Universidade Federal de São Carlos, 2019-03-29)
Filtration processes using fibrous filter media are very used to retain microparticles in a stream air due to its simple use, low operational cost and high collection efficiency. However, the study of submicron particles ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
Avaliação de adsorventes obtidos a partir de resíduos agroindustriais para a remoção dos inibidores gerados no pré-tratamento da biomassa lignocelulósica
(Universidade Federal de São Carlos, 2019-02-26)
The pretreatment of lignocellulosic biomass generates phenolic compounds and furaldehydes that inhibit the enzymes and yeast used in the process of hydrolysis of cellulose and alcoholic fermentation. In this context, the ...
Modificação de meios filtrantes com nanomateriais para controle de bioaerossóis
(Universidade Federal de São Carlos, 2018-06-15)
People are increasingly wasting their time in indoors environments, in these locations there is a risk of contagion from diseases transmitted by the airways, due to low rates of air exchange. Thus, the number of causative ...
