Silica is very often the catalyst support of choice for transition metal oxides such as titania, and specially anatase. Titania is an excellent absorber and photocatalyst for many organic molecules degradation. In order ...

Formation of Cu–C composite is a difficult technological problem: carbon is practically insoluble in copper. We show that the heat treatment of the Cu–C composite leads to the formation of a thin (approximately 50 nm) ...

Evaluation is an important activity during solution design. Although there are specific evaluation methods for digital design, little is investigated about their effects on design process. This work presents a case study ...

Os meios de comunicação digitais presenciaram a emergência das interfaces culturais a partir da última década do século XX. Fruto do desenvolvimento de pesquisa em ciência computacional, especificamente sobre a questão da ...

The effect of dextran sulfate (DS) on distearoyl phosphatidyl glycerol (DSPG) and distearoyl phosphatidic acid (DSPA) films formed in the presence of Ca2Cl, LiCl or KCl as aqueous electrolytes, was analyzed by cyclic ...

Thin films of tin dioxide (SnO2) are deposited by the sol-gel-dip-coating technique, along with GaAs layers, deposited by the resistive evaporation technique. The as-built heterojunction has potential application in ...
