Síntese de furanos trissubstituídos via reações de oxopaladação aeróbica
(Universidade Federal de São Carlos, 2019-02-25)
Furans are important heterocyclics with broad application in synthesis as a building block, frequently presented in a wide range of compounds that exhibit biological activity, including natural products. Intramolecular ...
Prospecção química do metabolismo de fungos endofíticos isolados de maçã (Malus domestica) e goiaba (Psidium guajava)
(Universidade Federal de São Carlos, 2014-10-31)
Few studies are targeted concerning the chemistry of the secondary metabolism from endophytic fungi associated to edible fruits. In this sense, it is worth to explore the the microbial metabolic skills, particularly from ...
Estudo fitoquímico e bioatividade de espécies de Meliaceae sobre Spodoptera frugiperda e análises espectroscópicas do inseto sob a ação da cedrelona
(Universidade Federal de São Carlos, 2014-10-23)
Spodoptera frugiperda is a major pest of maize and its damage may lead to reduction of agricultural production. The use of synthetic insecticides has been the primary method of pest control, but their indiscriminate use ...
Estudos cristaloquímicos e teóricos de derivados do decahidrofenantreno
(Universidade Federal de São Carlos, 2012-08-24)
This work is a contribution to the study of the crystal, molecular and supramolecular structures as well as the conformation in vacuum of
decahydrophenantrene derivatives.

Estudo químico e histoquímico das glândulas metapleural e labial de formigas cortadeiras e a influência destas nas relações simbiontes presentes nos jardins de fungo
(Universidade Federal de São Carlos, 2015-02-18)
Leaf-cutting ants are considered the most derived insects on the planet. The
performance in maintaining the aseptic conditions of the colonies is a key factor
of the ecological success of these ants. Several defenses are ...
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, ...
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 ...
Estudo da eletrodeposição dos sistemas Mo-Zn-Cu e Ni-Mo-Cu com aplicação na reação de desprendimento de hidrogênio
(Universidade Federal de São Carlos, 2018-02-27)
Molybdenum compounds and alloys have large applicability due to its great properties such as: corrosion protection and electrocatalytic activity. This work reports the electrodeposition study of Mo-Zn-Cu and Ni-Mo-Cu ...
Estudo da eletro-oxidação de moléculas orgânicas pequenas sobre multicamadas metálicas Ptpc/Rh/Pt e Ptpc/Ru/Pt utilizando FTIR in situ
(Universidade Federal de São Carlos, 2018-09-06)
The modification of platinum-based electrodes for the efficiency optimization of the fuel cells has generated a great scientific interest, due to the problems associated with the poisoning of the catalytic surface. In ...
Complexos contendo bases de Schiff simétricas e não-simétricas: I – Complexos mono- e trinucleares de Níquel(II) e de Cobre(II) com ligantes do tipo salen para oxidação de catecóis; II – Complexos de Zinco(II) com aminotroponiminatos para polimerizações
