Mechanical and thermodynamical properties of β Cu Al Mn alloys along the Cu3Al → Cu2AlMn compositional line
(Pergamon-Elsevier Science Ltd, 2020-10)
The elastic properties of Cu − Al − Mn alloys with compositions along the Cu3Al → Cu2AlMn line and bcc-based structures, are studied by means of first-principles calculations. From the calculated elastic constants, the ...
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 ...
