    • Core–shell behavior and exchange bias of Fe-doped CuO nanoparticles 

      Oliveira, Aline Alves; Valerio-Cuadros, Marlon Ivan; Brito, Alex Soares de; Tupan, Lilian Felipe da Silva; Ivashita, Flávio Francisco; Geshev, Julian Penkov; Paesano Junior, Andrea (2020) [Artículo 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 

      Simon, Ícaro Ariel; Medeiros, Natália Goedtel; Garcia, Ketlin Correia; Soares, Rosane Michele Duarte; Rosa, Aline Tais da; Silva, Jacqueline Arguello da (2015) [Artículo 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 

      Brandt, Iuri Stefani; Tumelero, Milton André; Martins, Cesar Augusto; Campos, Cristiani Silveira; Faccio, Ricardo; Pasa, Andre Avelino (2018) [Artículo 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 

      Pelegrini, Silvia; Tumelero, Milton André; Brandt, Iuri Stefani; Della Pace, Rafael Domingues; Faccio, Ricardo; Pasa, Andre Avelino (2018) [Artículo 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 

      Wang, Zhaosheng; Qureshi, Navid; Yasin, Shadi; Mukhin, Alexander; Ressouche, Eric; Zherlitsyn, Sergei; Skourski, Yurii; Geshev, Julian Penkov; Ivanov, Vsevolod; Gospodinov, Marin; Skumryev, Vassil (2016) [Artículo 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 ...
