Spin Switching in Electronic Devices Based on 2D Assemblies of Spin‐Crossover Nanoparticles

02.01.2015 | Julien Dugay, Mónica Giménez‐Marqués, Tatiana Kozlova, Henny W. Zandbergen, Eugenio Coronado, Herre S. J. van der Zant, Advanced Materials, 2015

Two‐dimensional assemblies of triazole‐based spin‐crossover nanoparticles (SCO NPs) presenting different morphologies are prepared and electrically characterized. The thermal hysteresis loop in the electrical conductance near room temperature correlates with the NP morphologies and their 2D ...

Kinetics of dispersion of nanoparticles in thin polymer films at high temperature

24.12.2014 | Nafisa Begam; Sivasurender Chandran; Nupur Biswas; Jaydeep Kumar Basu, Soft Matter, 2014

We report the first detailed study of the kinetics of dispersion of nanoparticles in thin polymer films using temperature dependent in-situ X-ray scattering measurements. We show a comparably enhanced dispersion at higher temperatures for systems which are otherwise phase segregated at room ...
