Core–shell behavior and exchange bias of Fe-doped CuO nanoparticles
(2020) [Artigo de periódico]Cu1−xFexO nanoparticles were prepared using a freeze-drying process followed by heat treatment. The particles were then characterized using Mössbauer spectroscopy and magnetization techniques. The results revealed complex ... -
CuO nanofibers immobilized on paraffin-impregnated graphite electrode and its application in the amperometric detection of glucose
(2015) [Artigo de periódico]1-D nanostructures are promising materials for development of electrochemical devices offering benefits such as fast electron transfer rates and large surface areas. Copper oxide nanofibers (CuONFs) synthesized by ... -
Defects controlling electrical and optical properties of electrodeposited Bi doped Cu2O
(2018) [Artigo de periódico]Doping leading to low electrical resistivity in electrodeposited thin films of Cu2O is a straightforward requirement for the construction of efficient electronic and energy devices. Here, Bi (7 at. %) doped Cu2O layers ... -
Electrodeposited Cu2O doped with Cl : electrical and optical properties
(2018) [Artigo de periódico]For understanding the electrical and optical properties of electrodeposited Cl-doped Cu2O thin films, we have studied layers with increasing thickness and Cl concentrations of 0.8 and 1.2 at. %. The deposits were characterized ... -
Magnetoelectric effect and phase transitions in CuO in external magnetic fields
(2016) [Artigo de periódico]Apart from being so far the only known binary multiferroic compound, CuO has a much higher transition temperature into the multiferroic state, 230 K, than any other known material in which the electric polarization is ...
