Portable point-of-use photoelectrocatalytic device provides rapid water disinfection
Portable water purification devices are needed to provide safe drinking water in rural communities, developing communities with low quality centralized water distribution, and military or recreational applications. Filtration, ...
TiO2:Cex onto Al Clays for Photocatalytic Solar Water Disinfection
A novel methodology was employed to prepare new nanocomposites with photocatalytic properties based on Ce-doped TiO2 nanoparticles arranged over a layered silicate. The catalysts were porous materials formed by exfoliated ...
Water treatment plant prototype with ph control modeled on fuzzy logic for removing arsenic using fe(VI) and fe(III)
(Multidisciplinary Digital Publishing Institute, 2020)
This study proposes a fuzzy control strategy embedded in a Siemens IoT2040 gateway developed for removing inorganic arsenic from synthetic underground water in a treatment plant prototype. The prototype is used to dose a ...
Synthesis, Spectroscopic Characterization, Structural Studies, and in Vitro Antitumor Activities of Pyridine-3-carbaldehyde Thiosemicarbazone Derivatives
Eight new thiosemicarbazone derivatives, 6-(1-trifluoroethoxy)pyridine-3-carbaldehyde thiosemicarbazone (1), 6-(4'-fluorophenyl)pyridine-3-carbaldehyde thiosemicarbazone (2), 5-chloro-pyridine-3-carbaldehyde thiosemicarbazone ...
Physicochemical characterization and oxidative stability of microencapsulated edible sacha inchi seed oil by spray drying
(Consejo Superior de Investigaciones Científicas, 2020)
The aim of this work was to obtain sacha inchi oil (SIO) microcapsules from two different spe-cies, Plukenetia volubilis L. (SIVO) and Plukenetia huayllabambana L. (SIHO), using different biopolymers as wall materials and ...
Development of a Fuzzy Logic-Based Solar Charge Controller for Charging Lead–Acid Batteries
The design and implementation of a solar charge controller for lead–acid batteries is intended to supplement a component of the water purification module of the water treatment unit for natural disaster relief. This unit ...
Role of empowerment and identification with work teams in innovation climate
(Fundacao Getulio Vargas, Escola de Administracao de Empresas de Sao Paulo, 2020)
Several studies argue that an organizational climate oriented to promote innovation generates greater competitiveness in companies. However, very few researchers have explored the factors that lead to the formation of ...
Confined benzene within InOF-1: Contrasting CO2 and SO2 capture behaviours
(Royal Society of Chemistry, 2020)
The confinement of small amounts of benzene in InOF-1 (Bz@InOF-1) shows a contradictory behavior in the capture of CO2 and SO2. While the capture of CO2 is increased 1.6 times, compared to the pristine material, the capture ...
Treatment of irrigation water infested with nematodes using a solar photoreactor
(Desalination Publications, 2020)
The objective of this study was to assess the efficacy of the disinfection of irrigation water loaded with the plant-parasitic nematode Meloidogyne incognita using a solar photoreactor. The photoreactor was comprised of a ...
Ultraviolet concentration factor of a truncated compound parabolic concentrator under different weather conditions
(Pleiades Publishing, 2020)
This study presents the results of ultraviolet radiation measurement in a truncated compound parabolic concentrator. The measurements were performed by using of a portable ultraviolet sensor both inside and outside the ...
