Nanostructured Screen-Printed Electrodes Modified with Self-Assembled Monolayers for Determination of Metronidazole in Different Matrices
(Sociedade Brasileira de Quimica, 2014)
Acceso abierto
This paper describes the development of a sensor for the determination of metronidazole using a simple method involving the creation of nanoporous structures on gold electrodes followed by modification with self-assembled ...
Synthesis and Characterization of ZnO Nanorod Films on PET for Photocatalytic Disinfection of Water
(Science & Technology Network, Inc., 2015)
Acceso abierto
ZnO nanorods (ZnO NRs) were grown on ZnO seeded polyethylene tert-phtalate (PET) substrates obtained from
recycled soda bottles at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO
seeds ...
Design and construction of a fresnel linear distiller
(Allerton Press, Inc., 2014)
Acceso restringido
It was designed a Fresnel linear distiller based on optical calculations obtained from taking into account Lima's latitude value, Earth inclination angle and heat absorber cavity's dimensions. The 5.6 m^sup 2^ reflective ...

Desalination using a parabolic-trough concentrator
(Allerton Press Inc., 2012)
Acceso abierto
There are presented desalination results by using a parabolic-trough concentrator (PTC) device of 5.5 m2, 0.7 m of line focal distance and aligned in the East—West direction. The length of the PTC is 2.5 m and its rectangular ...
Adsorption of antipyrine by activated carbons from FeCl3-activation of Tara gum
(Elsevier BV, 2018)
Acceso restringido
Activated carbons were synthesized by FeCl3-activation of Tara gum at different temperatures (400–1000 °C).
The activating agent and the precursor were physically mixed at different ratios (r= FeCl3:precursor,
0.5–3.0 ...
Elimination of Escherichia coli in Water Using Cobalt Ferrite Nanoparticles: Laboratory and Pilot Plant Experiments
(Multidisciplinary Digital Publishing Institute, 2019)
Acceso abierto
This paper focuses on the synthesis of cobalt ferrite nanoparticles by the sol–gel method
and their photocatalytic activity to eliminate bacteria in aqueous media at two di erent scales: in a
laboratory reactor and a ...
Elimination of chemical oxygen demand from domestic residual water by electrocoagulation with aluminum and iron electrodes
(Instituto de Pesquisas Ambientais em Bacias Hidrograficas, 2018)
Acceso abierto
This research determined the efficiency of removal of chemical oxygen demand (COD) by an electrocoagulation process. An electrocoagulation reactor with aluminum and iron electrodes was used to treat water from the treatment ...
