Surface spin disorder in nickel ferrite nanomagnets studied by in-field Mossbauer spectroscopy
(SPRINGER, 2008)
The magnetic structure of NiFe(2)O(4) nanoparticles has been investigated by means of Mossbauer spectra at T=4.2 K in applied fields up to 12 T. Four samples were studied, with mean particle diameters ranging from 4.3 to ...
A Comparative Analysis of In-Medium Spectral Functions for N(940) and N (au)(1535) in Real-Time Thermal Field Theory
(Springer, 2014-12-01)
In the real-time thermal field theory, the nucleon self-energy at finite temperature and density is evaluated where an extensive set of pion-baryon (pi B) loops are consider. On the other side, the in-medium self-energy ...
Strain relaxation and stress-driven interdiffusion in InAsInGaAsInP nanowires
(2007-08-17)
The authors have investigated strain relaxation in InAsInGaAsInP nanowires (NW's). Transmission electron microscopy images show an additional stress field attributed to compositional modulation in the ternary layer, which ...

Estimating hardness of eucalyptus wood with a portable hardness tester
(2012-12-01)
More than 80% of the 29600 km of the Brazilian railroad mesh employs wooden sleepers. The problem of hard availability of native wood for this purpose leads to the alternative use of reforestation species to produce sleepers. ...
