In this way, the material mimics the excitatory response of pressure-sensing neurons in the human skin. The composites, formed of silicone and graphitic nanoparticles, were prepared in several allotropic forms and functionalized with naphthalene diimide molecules. A systematic study is presented of the negative differential resistance (NDR) region of the current-voltage curves, which is responsible for the material’s active properties. This study was conducted as a function of temperature, graphite filling fraction, scaling to reveal the break-up of the samples into electric field domains at the onset of the NDR region, and an electric-field induced metal-insulator transition in graphite nanoparticles. The effect of molecular functionalization on the miscibility threshold and the current-voltage curves is demonstrated. Room-temperature and low-temperature measurements were performed on these composite films under strains using a remote-controlled, custom-made step motor bench.Springer theses.SiliconesNanoparticlesGraphiteSilicones.Nanoparticles.Graphite.530.41Littlejohn Samuel David1062869MiAaPQMiAaPQMiAaPQBOOK9910300382703321Electrical Properties of Graphite Nanoparticles in Silicone2528831UNINA01896nam 2200457z- 450 9910346721203321202102111000073722(CKB)4920000000094489(oapen)https://directory.doabooks.org/handle/20.500.12854/49886(oapen)doab49886(EXLCZ)99492000000009448920202102d2017 |y 0gerurmn|---annantxtrdacontentcrdamediacrrdacarrierIm Orbit einstellbare Ausgangsfilter und -multiplexerKIT Scientific Publishing20171 online resource (VIII, 203 p. p.)Karlsruher Forschungsberichte aus dem Institut für Hochfrequenztechnik und Elektronik3-7315-0722-6 Generally, communication satellites do not allow to flexibly react to changes in demand. This work presents theoretical and practical principles allowing to flexibly reconfigure the frequency plan of an output multiplexer. Particularly, based on the investigations performed in this work for the first time it is possible to realize manifold-based multiplexers with multiple channels which can be reconfigured in orbit for both center frequency and bandwidth during the life-time of the satellite.Technology: general issuesbicsscBandbreitebandwidtheinstellbarfilterFiltermultiplexerMultiplexerreconfigurablesatellite communicationSatellitenkommunikationTechnology: general issuesArnold Christianauth1227258BOOK9910346721203321Im Orbit einstellbare Ausgangsfilter und -multiplexer3022275UNINA
