Journal ArticleDOI
Ternary nanocomposites of reduced graphene oxide, polyaniline and hexaniobate: hierarchical architecture and high polaron formation.
Claudio Silva,Maria Iliut,Christopher A. Muryn,Christian Berger,Zachary Coldrick,Vera R. L. Constantino,Marcia L. A. Temperini,Aravind Vijayaraghavan +7 more
TL;DR: The preparation and characterisation of a new nanocomposite composed of polyaniline (PANI), reduced graphene oxide (rGO) and hexaniobate (hexNb) nanoscrolls presents promising properties for development of new materials in the film form on substrates for sensing or corrosion protection for example.
Journal Article
Antipathetic relationships among adolescents: Exploring prevalence, gender differences, and stability in the United States and Chile
TL;DR: In this paper, a longitudinal study of adolescents in Chile and United States showed that antipathy was unstable as particular rela- tionships (with the same peer over time), even though adolescents who held mutually dislike relations with peers at time 1 were more likely to hold similar interpersonal relations over time per se.
Proceedings ArticleDOI
Track initialization from incomplete measurements
TL;DR: In this article, an analytical approach to initialize the filter from a minimum number of observations is proposed, with the possibility to estimate only sub-sets of parameters, and to reliably model resulting added uncertainties by the covariance matrix.
Journal ArticleDOI
A method for a column-by-column EELS quantification of barium lanthanum ferrate.
Judith Lammer,Christian Berger,Stefan Löffler,Daniel Knez,Paolo Longo,Gerald Kothleitner,Ferdinand Hofer,Georg Haberfehlner,Edith Bucher,Werner Sitte,Werner Grogger +10 more
TL;DR: In this paper , the concentration of two elements within equivalent atomic columns from STEM-EELS elemental maps was determined by using parameters obtained from the actual experiment, and the results were then used as prior information during the Rietveld refinement in XRD measurements in order to differentiate between barium and lanthanum.
