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 ...
In vitro antiproliferative activity of palladium(II) thiosemicarbazone complexes and the corresponding functionalized chitosan coated magnetite nanoparticles

This work reports the synthesis and characterization of palladium(II) complexes Pd(L1)2 (1), Pd(L2)2 (2), Pd(L3)2 (3) and Pd(L4)2 (4), where L1H: 1-naphthaldehyde thiosemicarbazone; L2H: 4-phenyl-(1-naphthaldehyde)thiose ...
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 ...

Nanostructured Sensors for Determination of 3-(3,4-Dichlorophenyl)-1,1-Dimethylurea Based in Molecularly Imprinted Polymers (MIPs) Deposited in Screen Printed Carbon Nanotubes
(The Electrochemical Society, 2015)
Acceso abierto
A sensor based on molecularly imprinted polymers (MIP) was
developed for determination of 3-(3,4-Dichlorophenyl)-1,1-
dimethylurea (diuron). The MIP were synthesized by free radical
polymerization in wich diuron acted ...
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 ...
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 ...

(Sociedad Química del Perú, 2013)
Acceso abierto
Un problema de la enseñanza – aprendizaje del análisis químico instrumental es el alto costo de la instrumentación comercial, incluyendo aspectos de mantenimiento y servicio. Esto limita el acceso de los estudiantes a la ...
The role of seeding in the morphology and wettability of ZnO nanorods films on different substrates
(Elsevier BV, 2013)
Acceso restringido
Spray pyrolysis (SP) and spray-gel (SG) techniques were used to deposit ZnO seeds on Fluor doped tin oxide glasses (FTO), heated at 350 ¿C or 130 ¿C, and PET heated at 90 ¿C. The effect of seeding on the morphology and ...
Desalination using a parabolic-trough concentrator
(Allerton Press Inc., 2012)
