Intelligence in Peru: Students' results in Raven and its relationship to SES.
(Elsevier, 2015)
Acceso restringido
Several studies have tried to estimate the average cognitive ability level in Peru. The results oscillated between IQ 90 (Lynn & Vanhanen, 2002) and 85 (Lynn & Vanhanen, 2006, 2012). Moreover, regional studies conducted ...
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 ...
Influence of Pyrolytic Seeds on ZnO Nanorod Growth Onto Rigid Substrates for Photocatalytic Abatement of Escherichia coli in water
(IWA Publishing, 2014)
Acceso restringido
ZnO nanorods (ZnO NRs) were grown on ZnO seeded fluorine doped tin oxide (FTO) substrates at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO seeds were deposited on the FTO substrate ...
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 ...
