Amyloid-ß-peptide reduces copper(II) to copper(I) independent of its aggregation state
(Sociedad de Biología de Chile, 2000)
Preparation and characterization of Zno/CuO semiconductor and photocatalytic activity on the decolorization of direct red 80 azodye
(2015-12-01)
Zinc oxide, an n-type semiconductor, has been used as photocatalyst for contaminated water purification by organic compounds. The addition of a p-type semiconductor as copper oxide could increase the catalytic efficiency ...

(2020-01-01)
The preparation of graphene oxide and the modification of its surface directly with copper pentacyanonitrosylferrate (III) nanoparticles are presented in this work, as well as the characterization of the materials using ...
On the electrochemical behavior of Cu-16%Zn-6.5%Al alloy containing the β'-phase (martensite) in borate buffer
(2013-07-11)
In this work, the electrochemical behavior of Cu-16(wt.%)Zn-6.5(wt.%)Al alloy containing the β'-phase (martensite) was studied in borate buffer solution (pH 8.4) by means of open-circuit potential (EOC), electrochemical ...

Oxidation of copper nanoparticles in water: mechanistic insights revealed by oxygen uptake and spectroscopic methods
(Royal Society of Chemistry, 2013-02)
Oxidation of aqueous ∼8 nm unprotected copper nanoparticles takes place under air in approximately 2 hours at 30 °C to give Cu2+ as a final product through an intermediate Cu+ species. At 5 °C the process is about 5 times ...
Copper nanoparticles grown under hydrogen: Study of the surface oxide
(Elsevier, 2011)
Copper nanoparticles with sizes between 10nm and 50nm were grown by condensation in hydrogen
at pressures from 10 Pa to 1200 Pa. The crystallite size ranged from 10nm to 25nm using the Scherrer
method. X-ray diffraction ...
Antioxidant effect of 5-amino salicylic acid on copper-mediated LDL oxidation
(Society of Biology of Chile, 2007)
The antioxidant effect of 5-Aminosalicylic acid (5-ASA) on copper-mediated LDL oxidation was followed either by the emitted chemiluminiscence (CL) or by UV-vis spectroscopy. 5-ASA addition extends the lag phase in a ...
