Effect of minor Co additions on the crystallization and magnetic properties of Fe(Co)NbBCu alloys
Torrens Serra, Joan; Bruna Escuer, Pere; Roth, Segmar; Rodríguez Viejo, Javier; Clavaguera Mora, Maria Teresa (2010)
Article
Accés obertThe effect of partial replacement of Fe by Co (up to 8 %) on thermal stability, structure and magnetic properties of FeNbBCu alloys has been explored in this paper. The results indicate that Co reduces the stability against ... -
Electron spin resonance on single-walled carbon nanotubes obtained from different sources
Ferrer Anglada, Núria; Abiad Monge, Aida; Roth, Segmar (2010-12)
Article
Accés restringit per política de l'editorialWeused electron spin resonance (ESR) to analyze several kinds of single-walled carbon nanotubes (SWNTs) synthesized by different methods. We observed that ESR is a sensitive probe that can be used to observe major differences ... -
Flexible, transparent electrodes using carbon nanotubes
Ferrer Anglada, Núria; Iqbal, Muhammad Zahir; Pérez Puigdemont, Jordi; Figueras, Jordi; Roth, Segmar (2012-12-10)
Article
Accés obertWe prepare thin single-walled carbon nanotube networks on a transparent and flexible substrate with different densities, using a very simple spray method. We measure the electric impedance at different frequencies Z(f) in ... -
Single-walled carbon nanotubes characterization by Electron Spin Resonance spectroscopy
Abiad Monge, Aida; Pérez Puigdemont, Jordi; Ferrer Anglada, Núria; Roth, Segmar (2010)
Text en actes de congrés
Accés restringit per acord de confidencialitatCarbon nanotubes (CNTs) are interesting candidates for the development of new electronic devices and sensors due to their small size and their mechanical, optical and electrical properties [1-6]. Well-characterized ...
