Thermal, pressure and light switchable spin-crossover materials
2005
This article reviews the most relevant chemical and structural aspects that influence the spin-crossover phenomenon (SCO). Special attention is focussed on the recent development of SCO coordination polymers. The different approaches currently being explored in order to achieve multifunctionality in SCO materials are discussed.
Spin Crossover – Quo Vadis?
2013
This retrospective essay is an attempt to span the bridge over eight decades of research on spin crossover (SCO), one of the most fascinating dynamic electron structure phenomena of inorganic coordination chemistry. The occurrence of SCO compounds of 3d transition metal ions and their characterization regarding magnetic, optical, vibrational, structural, and thermodynamic properties are briefly addressed. Selected case studies of chemical influences and physical effects (pressure, magnetic field, light) on SCO behavior are discussed. Particular attention is paid to the importance of Mossbauer spectroscopy in SCO studies. Light-induced excited spin state trapping (LIESST) and related photoph…
Temperature dependence of desolvation effects in hydrogen-bonded spin crossover complexes
2021
The synthesis, crystal structure and (photo)magnetic properties of the anhydrous spin crossover salt of formula [Fe(bpp)2](C6H8O4) (1) (bpp = 2,6-bis(pyrazol-3-yl)pyridine; C6H8O4 = adipate dianion), obtained by desolvation at 400 K of the original tetrahydrate in a single-crystal-to-single-crystal (SC–SC) transformation, are reported. This work offers a comparison between this compound and the previously reported hydrated material ([Fe(bpp)2](C6H8O4)·4H2O, 1·4H2O), highlighting the significance of the thermal conditions used in the dehydration-rehydration processes. In both compounds, a hydrogen-bonded network between iron(II) complexes and adipate anions is observed. The original tetrahyd…
Insertion of a [Fe II (pyimH) 3 ] 2+ [pyimH = 2‐(1 H ‐Imidazol‐2‐yl)pyridine] Spin‐Crossover Complex Inside a Ferromagnetic Lattice Based on a Chiral…
2015
The insertion of the [FeII(pyimH)3]2+ [pyimH = 2-(1H-imidazol-2-yl)pyridine] spin-crossover complex into a ferromagnetic bimetallic oxalate network affords the hybrid compound [FeII(pyimH)3][MnIICrIII(ox)3]2·X (ox = C2O42–). This spin-crossover complex templates the growth of crystals formed by a chiral 3D oxalate network. The magnetic properties of this hybrid magnet show the coexistence of long-range ferromagnetic ordering at 4.5 K and a spin crossover of the intercalated [FeII(pyimH)3]2+ complex above 250 K. The compound presents a light-induced excited spin-state trapping (LIESST) effect below 60 K although with limited photoconversion (less than 8 %).
Extended View Angle Integral Imaging 3D Display using Smart Pseudoscopic-to-orthoscopic Conversion with Head Tracking
2016
We overview a head tracking integral imaging display using the smart pseudoscopic-to-orthoscopic conversion method. The crosstalk for a large viewing angle in integral imaging is eliminated by generating a new set of elemental images.
An overview of head tracking integral imaging three-dimensional display using smart pseudoscopic-to-orthoscopic conversion
2017
We overview a previously reported head tracking integral imaging three-dimensional (3D) display to extend viewing angle accommodated to a viewer's position without the crosstalk phenomenon. A head detection system is applied to obtain the head position and rotation of a viewer, and a new set of elemental images is then computed using the smart pseudoscopic-to-orthoscopic conversion (SPOC) method for head tracking 3D display. Experimental results validate the proposed method for high quality 3D display with large viewing angle.
Kjønn, likestilling og makt i #MeToo
2018
Masteroppgave samfunnskommunikasjon KOM500 - Universitetet i Agder 2018 Bakgrunnen for denne oppgaven har vært egen interesse for #MeToo-kampanjen og hvilken virkning den har hatt på samfunnet. Det har derfor vært av interesse å bruke en kritisk diskursanalyse om fenomenet som ser på problemstillingen om hvordan mediediskursen rundt #MeToo-kampanjen fremstiller kjønn, likestilling og makt i norske medier. Gjennom en næranalyse av tre artikler har denne oppgaven sett på hvordan #MeToo-kampanjen blir fremstilt i disse artiklene. Hvilke virkemidler journalistene bruker for å få frem sine poeng, bruk av kilder og språkbruk. Tekstene er hentet fra Aftenposten, NRK og Klassekampen. Fremgangsmåten…
Crosstalk of the plasma contact system with bacteria.
2012
Activation of the plasma contact system triggers several cascade systems such as the kallikrein-kinin system, the intrinsic pathway of coagulation, the classical complement cascade and the fibrinolytic system. Recent studies have shown a critical role of the contact system for arterial and venous thrombus formation and thromboembolic disease. In contrast, the function of the contact system for host-defense reactions and its physiological functions have remained enigmatic. Experimental animal studies and clinical data have linked the contact system to bacterial infections with implications for sepsis disease. The present review summarizes the role of the contact system and its activation for…
Der Gerichtshof der reinen Vernunft
2021
Die verschiedenen Urteilsstufen des Gerichtshofes der reinen Vernunft bieten einen privilegierten Zugang zur Erfassung des kantischen Begriffs menschlicher Vernunft in seiner vollen Komplexität. Wenn „menschliche Vernunft“ einerseits ein Vermögen benennt, das zur Grundausstattung unserer Erkenntnisanlagen gehört und als solches „subjektiv als ein menschliches Erkenntnisvermögen“ angesehen wird, dann ist andererseits der Mensch aufgrund eines Besitzes der Vernunft Zeuge von Entwürfen und Ansprüchen, bei deren Entsprechung er angesichts seiner Natur und seiner spezifischen Fähigkeiten nicht entscheidend ist. Die Kritik erfüllt also ihre ureigenste Aufgabe. Und das nicht nur, weil sie den Legi…
