SYNTHETIC METHODOLOGIES INVOLVING PHOTOCHEMICAL AND ELECTROCHEMICAL REACTIONS IN BOTH BATCH AND CONTINUOUS FLOW CONDITIONS. Initially (Chapter 1), general aspects of the studied reactions were presented and in the chapter ...
Desenvolvimento e aplicação do software HERisk para avaliação espaço-temporal de riscos: estudo de caso do rio Monjolinho e suas águas tratadas com membranas de matriz mistas
(Universidade Federal de São Carlos, 2023-03-27)
This project proposes to develop new software for the spatio-temporal assessment of radiological, ecological, and human health risks, in addition to new mixed matrix membranes (MMMs) based on polyethersulfone (PES) and ...
Desenvolvimento de eletrocatalisadores de sulfeto de molibdênio para produção de hidrogênio via eletrólise da água
(Universidade Federal de São Carlos, 2023-03-31)
The amorphous molybdenum sulfide, MoSx, has shown to be an excellent electrocatalyst for the hydrogen evolution reaction (HER) and can be synthesized by electrodeposition. In this study, the electrodeposition of MoSx on ...
Seleção de padrões internos para análise elementar em métodos instrumentais com plasma induzido
(Universidade Federal de São Carlos, 2023-03-08)
This thesis approaches the challenges and strategies to use the internal standardization calibration method in two instrumental methods, i.e. inductively coupled plasma optical emission spectrometry (ICP-OES) and microwave ...
Avaliação da atividade fotoeletrocatalítica dos filmes de CuO/NiOx, CuO/Cu2O/CuS e WO3/MoO3-x frente a fotoeletrólise da água para a produção de H2 verde
(Universidade Federal de São Carlos, 2023-02-24)
The use of solar energy is essential for the future of humanity. In this context, the conversion of this energy into chemical energy, using low-cost technologies, such as photoelectrochemical cells (PECs), has gained ...
Development of Hematite-based photoanodes
(Universidade Federal de São Carlos, 2023-02-17)
Hydrogen production via Water Splitting has been considered one of the best solutions for energy shortages and environmental pollution. The use of hematite (α-Fe2O3) as a photoanode in photoelectrochemical hydrogen production ...
Material particulado atmosférico de São Carlos: identificação das fontes de emissões e seus impactos à saúde humana
(Universidade Federal de São Carlos, 2023-08-30)
Air pollution by particulate matter (PM) is one of the main environmental risks to human health. PM has different sizes, emission sources, and a wide range of substances may be present in it. Given this scenario, the ...
