Síntese de nanopartículas semicondutoras de seleneto de zinco (ZnSe) aquoso e análise dos subprodutos decorrentes dessa síntese
(Universidade Federal de São Carlos, 2012-07-20)
Zinc selenide (ZnSe) is a semiconductor material, which band gap is about 2.7 eV. It has many applications as blue light emission diode, data storage devices, laser diodes and waveguides optical fibers. Despite these several ...
Técnicas de bioinformática aplicadas ao estudo de poligalacturonases de fungos
(Universidade Federal de São Carlos, 2012-04-18)
Plant cell walls are composed of approximately 65% cellulose microfibrils and pectin. The latter is proteolytically degraded by the so-called pectinases enzymes (also known as pectinolytic enzymes). Pectinases may be either ...
