Photoelectrochemical cells (PECs) have been shown to be a promising system for H2 generation from photoelectrolysis of water. Among the semiconductors materials that have been studied for PECs, Sb2S3 stands out due to its ...
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 ...
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 ...
Estudo empírico-teórico de compósitos baseados em polímeros condutores para conversão e armazenamento de energia
(Universidade Federal de São Carlos, 2018-10-26)
The fast obsolescence of still functional devices causes an extensive e-waste generation and an exacerbated natural resources consumption for the manufacture of new products. In this sense, the development of abundant ...
