Evidence of random magnetic anisotropy in ferrihydrite nanoparticles based on analysis of statistical distributions
N. J. O. Silva, V. S. Amaral, L. D. Carlos +7
We show that the magnetic anisotropy energy of antiferromagnetic ferrihydrite depends on the square root of the nanoparticles volume, using a method based on the analysis of statis…
Matrix Assisted Formation of Ferrihydrite Nanoparticles in a Siloxane/Poly(Oxyethylene) Nanohybrid
Nuno J. O. Silva, Vitor S. Amaral, Veronica de Zea Bermudez +4
Matrix-assisted formation of ferrihydrite, an iron oxide hydroxide analogue of the protein ferritin-core, in a sol-gel derived organic-inorganic hybrid is reported. The hybrid netw…
Amine Functionalized Cross-Linked Hybrid Full Color Phosphors Lacking Metal Activator Ions
L. D. Carlos, R. A. Sa Ferreira, V. De Zea Bermudez +1
White light tunable phosphors are obtained from a sol-gel derived siliceous network to which oxyethylene units are covalently grafted by means of urea or urethane cross-linkages. T…
Ion-Chain Dynamics in Polymer Electrolytes
L. D. Carlos, A. L. L. Videira
Representing polyether-salt systems by chains of interacting coordination shells, defined by the cation and by its nearest ligands, we derive the interaction potential between clos…
