Efeito dos íons Ni2+ nas propriedades estruturais, ópticas e morfológicas do tungstato de prata
(Universidade Federal de São Carlos, 2015-07-17)
The tungstates are important compounds and known for their optical properties. In this work, solid solutions with nickel silver tungstate, 𝐴𝑔2−2𝑥𝑁𝑖𝑥𝑊𝑂4, ...
Acilação e alquilação fotoquímica de heteroarenos utilizando diacetil
(Universidade Federal de São Carlos, 2018-11-01)
N-heterocycles are important building blocks in the synthesis of bioactive compounds, besides that many of them are present in natural products. Most of the methodologies for heteroarene functionalization requires several ...
Nanomateriais semicondutores aplicados na fabricação de dispositivos eletroquímicos
(Universidade Federal de São Carlos, 2019-03-22)
This dissertation was subdivided into 3 different studies. In the first study, it was proposed the development of a photo-electrochemical system for the removal of caffeine in natural water samples. Photo-anodes made with ...
Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
Biotransformação de cicloadutos de Diels-Alder por células intactas de Penicillium brasilianum, endofítico de Melia azedarach
(Universidade Federal de São Carlos, 2014-03-27)
Endophytic microorganisms have a great enzymatic potential to biotransformate substances of natural and synthetic origin due to strategies developed during colonization to coexist with the plant in an initial hostile ...

belong to the family of ADAM (A disintegrin and ...
Obtenção e caracterização bioquímica de xilanases nativas e recombinante do fungo Leucoagaricus gongylophorus
(Universidade Federal de São Carlos, 2013-08-30)
Xylanases are enzymes which randomly cleave the main chain of xylan, the most abundant non-cellulosic polysaccharide of plants cell wall. Xylanases are commonly produced by a wide range of organisms including bacteria, ...
Estudo In vitro de nanocompósitos para a liberação lenta de nitrogênio sobre a alimentação animal
(Universidade Federal de São Carlos, 2016-03-29)
Supplementation with nonprotein
nitrogen (NPN) has been widely used in ruminant feeding in diets of low
quality forages. This is because these animals have a number of microorganisms
in the rumen able to use ammonia for ...
