(Universidade Federal de São Carlos, 2022-12-16)
Dexamethasone is a glucocorticoide, first synthesized in 1957, that is currently part of the World Health Organization's List of Essential Medicines. Thus, as na important drug, its potential for environmental contamination ...
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 ...
