Vogel-Fulcher analysis of relaxor dielectrics with the tetragonal tungsten bronze structure : Ba6MNb9O30 (M = Ga, Sc, In)
No full textIn-depth analysis of the relaxor behaviour of Ba6MNb9O30 (M= Ga, Sc, In) tetragonal tungsten bronze (TTB) ceramics was carried out. Powder x-ray diffraction and scanning electron microscopy were performed in order to confirm the formation of desired phases and to determine the microstructure. Low-temperature dielectric spectroscopy was used in order to characterise the dielectric properties of these materials; the degree of relaxor behaviour were investigated in relation with the increase of ionic radius of the M-cation on the B-site of the TTB structure. The dynamics of dielectric relaxation of dipoles was studied by fitting the dielectric permittivity data to the Vogel-Fulcher (VF) model in order to monitor the reproducibility and validity of the physical results. Restrictions to the VF fit were attempted besides the regular “free-fit” by constraining some of the fundamental relaxation parameters to physically sensible values. We show that Vogel-Fulcher fits are very sensitive to the fitting range resulting in a large range of fundamental parameters for the dielectric relaxation processes, and that the restriction of the frequency domain due to experimental noise or to instrumentation limits has a dramatic influence on the values obtained.Peer reviewe

Vogel- en Habitatrichtlijn: Consequenties voor Rijkswaterstaat
No full textRijkswaterstaat heeft als bevoegd gezag met betrekking tot de rijkswateren en als initiatiefnemer van (grootschalige) projecten de verantwoordelijkheid om zorgvuldig om te gaan met de Europese Vogel- en Habitatrichtlijn. Binnen Rijkswaterstaat zijn in de afgelopen periode vele vragen gesteld met betrekking tot deze richtlijnen, die zowel procesmatig als inhoudelijk van aard zijn. Veel van deze vragen hebben betrekking op activiteiten van Rijkswaterstaat in de kustzone. Om aan deze vragen tegemoet te komen heeft het RIKZ op verzoek van het hoofdkantoor van Rijkswaterstaat dit document opgesteld. Het document geeft een overzicht van de verplichtingen die voortvloeien uit beide richtlijnen en op welke manier (regionale) directies van Rijkswaterstaat hiermee om kunnen gaan bij de uitvoering van hun activiteiten. De nadruk wordt hierbij gelegd op het toetsen van plannen en projecten aan beide richtlijnen. De toetsing aan beide Europese richtlijnen wordt in twee schema\u92s gepresenteerd. Deze schema\u92s kunnen binnen bestaande procedures (b.v. vergunningverlening) worden toegepast. Iedere stap in het schema wordt expliciet toegelicht. Dit document kan geen antwoord geven op alle vragen, maar is bedoeld om medewerkers van Rijkswaterstaat die betrokken zijn bij toetsing aan de Vogel- en Habitatrichtlijn de juiste weg te wijzen. Een drietal activiteiten waarbij Rijkswaterstaat in de kustzone te maken krijgt met toetsing aan de Vogel- en Habitatrichtlijn worden als voorbeeld nader toegelicht
