Sachês compósitos biodegradáveis à base de amido visando o acondicionamento de nutrientes para aplicação como fertilizantes
(Universidade Federal de São Carlos, 2020-07-31)
The Brazilian agrarian system is responsible for a large part of the national GDP, even though agricultural production is dependent on foreign trade. In addition, many producers prioritize the use of NPK-type fertilizers ...
Caracterização das interações químicas entre os microrganismos simbiontes das formigas cortadeiras
(Universidade Federal de São Carlos, 2021-01-13)
The complex symbiosis in Attini ant nests inspires curiosity in different fields of research from Microbiology to Chemical Ecology. These ants cultivate their mutualist fungus for approximately 50 million years in structures ...
Estudo de distintos processos oxidativos avançados eletroquímicos (e-POA) e teste de um reator solar em escala semi-piloto
(Universidade Federal de São Carlos, 2021-02-12)
In this work, two different advanced oxidation processes (AOP) were investigated: i) electrochemical processes (electro FeredFenton and photoelectro Fered-Fenton with BDD and DSA® electrodes under UVA/UVC irradiation (9 ...
UVC-based advanced oxidation processes for water treatment: laboratory and pilot plant scale studies
(Universidade Federal de São Carlos, 2020-09-21)
The challenge of providing good-quality water free from contaminants of emerging concern (including organic microcontaminants; OMCs) and pathogens is one of the main hot topics worldwide. Thus, the efficiency of different ...
Imagens espectrais do processo de agregação da insulina por complexos metálicos luminescentes
(Universidade Federal de São Carlos, 2021-03-01)
Insulin is a protein hormone synthesized by β cells in the pancreas, which regulates the level of glucose in the blood. This protein was the first biopharmaceutical produced on an industrial scale for the treatment of ...
Avaliação in vitro da ação fotodinâmica antimicrobiana e antitumoral do complexo cis-[Ru(phen)2(pPDIp)]2+
(Universidade Federal de São Carlos, 2021-02-19)
Photodynamic therapy (PDT) activates a photosensitizer by visible or infrared light to generate cytotoxic oxygen species that lead to cell death. PDT is generally used in applications in superficial lesions and can be used ...
Calibração multivias em Laser-Induced Breakdown Spectroscopy (LIBS) para determinação de Ca, K e Mg em amostras de suplemento mineral para humanos
(Universidade Federal de São Carlos, 2021-03-25)
This work intends to present a new approach for modeling LIBS data resolved in time using multiway algorithms, aiming to achieve the advantage of second order. The algorithms evaluated in this study were: Multivariate Curve ...
Co-cultivo fúngico como estratégia para obtenção de metabólitos biologicamente ativos
(Universidade Federal de São Carlos, 2021-02-23)
In this work, the bactericidal, antiprotozoal, and inhibition of cathepsin V proteolytic activity of extracts from the axenic cultivation of six fungal species (Fusarium guttiforme, Pestalotiopsis diospyri, Phoma ...
Flow chemistry applied to hazardous reactions, and fluorophores synthesis with photophysics studies
(Universidade Federal de São Carlos, 2020-02-20)
Two distinct cases of continuous flow conditions applied to dangerous reactions are described. The first example is the continuous photooxygenation of a series of dienes that produces endoperoxides and / which are potentially ...
Desenvolvimento de dispersões sólidas e membranas baseadas em praziquantel-poli(álcool vinílico) na terapêutica de esquistossomose
(Universidade Federal de São Carlos, 2021-03-23)
Schistosomosis is a parasitic disease considered neglected and endemic in 75 countries. It is estimated that 240 million people are infected and 700 to 800 million people are at risk. Despite that, there is no effective ...
