Estudo fitoquímico biomonitorado de Duguetia lanceolata e Lithraea molleoides no controle de pragas agrícolas e processos de nanoencapsulamento
(Universidade Federal de São Carlos, 2016-04-29)
Leafcutter ants and maize weevil are responsible for great losses in Brazilian agriculture due to the difficult control of these pests. Natural products are becoming increasingly important, mainly in the search for non-toxic ...
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 ...
“Catalisadores Au/m-ZrO2 aplicados na conversão direta do etanol em acetato de etila: efeito do grau de recobrimento do suporte nas propriedades catalíticas”
(Universidade Federal de São Carlos, 2018-04-26)
In this present work, the direct formation of ethyl acetate from ethanol was studied using monometallic catalysts of Au supported on m-ZrO2. Other supports, such as MgO and SiO2, as well as Cu-based catalysts were prepared ...
Estudo da produção de nanofibras de carbono por fiação por sopro em solução a partir de poliacrilonitrila e lignina
(Universidade Federal de São Carlos, 2019-10-24)
Carbon nanofibers (NFC) are highly resistant materials and are widely used in the aerospace and battery industry. Methods such as eletrospinning and solution blow spinning (SBS) are used for the production of carbon ...
Metabolic discrimination of citrus species resistant and susceptible to black spot disease using multi-platform-based metabolomic approach
(Universidade Federal de São Carlos, 2020-08-31)
Citrus black spot (CBS) caused by the fungus Phyllosticta citricarpa. CBS causes several economic damages to commercial citrus orchards, such as fruit blemishes and premature fruit drop, leading to yield loss. There are ...
Evaluation of the composition of electronic waste hard disk using spectroanalytical techniques: proposition of fast and simple methods
(Universidade Federal de São Carlos, 2020-12-17)
The electronic waste is a worldwide problem of great magnitude with 53.6 Mt of waste generated in 2019. Unfortunately, the recycling rate is still very low. It is estimated that only 2% of the electronic waste is recycled ...
Modificação covalente de peptideos antimicrobianos e anticancerigenos para a melhoria de suas propriedades farmacológicas
(Universidade Federal de São Carlos, 2019-08-16)
Following the information obtained by a rational design study, cyclic and dimeric helical stabilized analogues of the peptide Cm-p5 were synthetized. The cyclic monomer showed an increased activity in vitro ...
