Caracterização óptica de nanopartículas de CuCl e CuBr sintetizadas em filmes ORMOSILs
(Universidade Estadual Paulista (Unesp), 2017-03-15)
A incorporação de nanopartı́culas em matrizes hı́bridas produz materiais com grande potencial para aplicações em diversas áreas de estudo. Na óptica, sua funcionalidade surge quando elétrons confinados em estruturas ...
Pd growth on Cu(111): stress relaxation through surface alloying?
(Elsevier Science BvAmsterdamHolanda, 2004)
A Cu2+-Cu/glassy carbon system for glyphosate determination
(Elsevier Science SA, 2019-04)
Cu° electrocrystallization onto glassy carbon (GC) at potentials between −0.4 V and −0.7 V is consistent with a 3D progressive nucleation mechanism and diffusion-controlled growth. Cu/GC electrode prepared at −0.6 V is ...
Photoelectrochemical reduction of CO2 on Cu/Cu2O films: Product distribution and pH effects
(Elsevier B.V., 2015-03-15)
This work focuses on photoelectrochemical CO2 reduction at a Cu/Cu2O electrode (1 x 1 cm(2)). The formation of methanol, ethanol, formaldehyde, acetaldehyde, and acetone was monitored during UV-visible radiation for 3 h ...
Estudio Electroquímico de electrodos de Carbón Vítreo modificados con el sistema Cu-ZSM5 inmovilizados con PMMA/MA
(2011-09-01)
In this work the commercial zeolite NH4-ZSM5 (Zeolite Molecular Sieve of porosity-5) was calcined in air to produce the protonated zeolite H-ZSM5, the copper incorporation into H-ZSM5 was performed by ion exchange obtained ...
Pleistocene recycling of copper at a porphyry system, Atacama Desert, Chile: Cu isotope evidence
(Springer, 2011)
We present Cu isotope data of hypogene and
supergene minerals from the Late Paleocene Spence Cu-Mo
porphyry in the Atacama Desert of northern Chile.
Chalcopyrite displays a restricted range of δ65Cu values
within the ...
