Journal ArticleDOI
Influence of Electronegative Substituents on the Binding Affinity of Catechol-Derived Anchors to Fe3O4 Nanoparticles
Esther Amstad,Andreas U. Gehring,Håkon Fischer,Venkatamaran V. Nagaiyanallur,Georg Hähner,Marcus Textor,Erik Reimhult +6 more
TL;DR: In this article, the authors investigated mechanistic binding aspects of five different anchors from this study that showed radically different efficiencies as dispersant anchors, namely nitroDOPA, nitrodopamine, DOPA, dopamine, and mimosine, using electron paramagnetic resonance, Fourier transform infrared spectroscopy, and UV−vis spectrograph.
Journal ArticleDOI
Thermal alteration of the magnetic mineralogy in ferruginous rocks
Ann M. Hirt,Andreas U. Gehring +1 more
TL;DR: The Northampton ironstone contains the paramagnetic minerals siderite and berthierine and a trace of the ferrimagnetic mineral magnetite as mentioned in this paper, and the magnetic fabric of this sedimentary rock, as defined by the anisotropy of magnetic susceptibility, is controlled by bedding compaction but is inverse (i.e., the maximum susceptibility axes are normal to the bedding plane).
Journal ArticleDOI
Ferromagnetic resonance and magnetic characteristics of intact magnetosome chains in Magnetospirillum gryphiswaldense
H. Fischer,Giovanni Mastrogiacomo,Jörg F. Löffler,Rolf Warthmann,Peter G. Weidler,Andreas U. Gehring +5 more
TL;DR: The magnetic properties of intact magnetosome chains in magnetospirillum gryphiswaldense bacteria were investigated by means of static and dynamic magnetic analyses and ferromagnetic resonance spectroscopy as mentioned in this paper.
Journal ArticleDOI
High temperature stability of natural maghemite: a magnetic and spectroscopic study
TL;DR: In this article, a combined magneto-mineralogical approach is used to diagnose maghemitization in magnetic grains of basaltic rock fragments from sand dunes in the Namibian desert in SW Africa.
Journal ArticleDOI
Simulation of ferromagnetic resonance spectra of linear chains of magnetite nanocrystals
TL;DR: In this paper, the authors have simulated FMR spectra of dilute suspensions of linear chains oriented randomly in space by modeling the chain as a Stoner−Wohlfarth-type rotation ellipsoid whose long axis coincides with an easy [111] axis of the cubic magnetocrystalline anisotropy system.
