Quantitative Comparison of 3D Pore Space Properties With Magnetic Pore Fabrics—Testing the Ability of Magnetic Methods to Predict Pore Fabrics in Rocks
Autor: Y. Zhou, M. Pugnetti, A. Foubert, P. Lanari, C. Neururer, A. R. Biedermann
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 23, Iss 10, Pp n/a-n/a (2022)
Abstract Pore fabrics characterize the anisotropy of pore space in rocks and influence the direction of fluid flow. This is important in reservoir characterization, and petroleum and geothermal energy exploitation. X‐ray computed micro‐tomography

A revised map of volcanic units in the Oman ophiolite: insights into the architecture of an oceanic proto-arc volcanic sequence
Autor: T. M. Belgrano, L. W. Diamond, Y. Vogt, A. R. Biedermann, S. A. Gilgen, K. Al-Tobi
Publikováno v: Solid Earth, Vol 10, Pp 1181-1217 (2019)
Numerous studies have revealed genetic similarities between Tethyan ophiolites and oceanic “proto-arc” sequences formed above nascent subduction zones. The Semail ophiolite (Oman–U.A.E.) in particular can be viewed as an analogue for this proto

Tough metal-ceramic composites with multifunctional nacre-like architecture
Autor: Erik Poloni, Florian Bouville, Christopher H. Dreimol, Tobias P. Niebel, Thomas Weber, Andrea R. Biedermann, Ann M. Hirt, André R. Studart
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-12 (2021)
Abstract The brick-and-mortar architecture of biological nacre has inspired the development of synthetic composites with enhanced fracture toughness and multiple functionalities. While the use of metals as the “mortar” phase is an attractive opti

Explaining the large variability in empirical relationships between magnetic pore fabrics and pore space properties
Autor: Andrea R. Biedermann, Yi Zhou, Michele Pugnetti
Publikováno v: Biedermann, Andrea R.; Pugnetti, Michele; Zhou, Yi (2021). Explaining the large variability in empirical relationships between magnetic pore fabrics and pore space properties. Geophysical journal international, 227(1), pp. 496-517. Oxford University Press 10.1093/gji/ggab230
SUMMARYThe magnetic anisotropy exhibited by ferrofluid-impregnated samples serves as a proxy for their pore fabrics, and is therefore known as magnetic pore fabric (MPF). Empirically, the orientation of the maximum susceptibility indicates the averag

Publikováno v: Neuropediatrics. 52:383-389
Background Cerebral palsy (CP) is the most common motor impairment in childhood and often accompanied by a broad spectrum of comorbidities. Data are sparse concerning visual impairment (VI) and functional classification among CP children. Objective T

Ferrofluid Impregnation Efficiency and Its Spatial Variability in Natural and Synthetic Porous Media: Implications for Magnetic Pore Fabric Studies
Autor: Michele Pugnetti, Yi Zhou, Andrea R. Biedermann
Publikováno v: Pugnetti, Michele; Zhou, Yi; Biedermann, Andrea R (2022). Ferrofluid Impregnation Efficiency and Its Spatial Variability in Natural and Synthetic Porous Media: Implications for Magnetic Pore Fabric Studies. Transport in porous media, 144(2), pp. 367-400. Springer 10.1007/s11242-022-01809-0
Magnetic pore fabrics (MPF) are an efficient way to characterize pore space anisotropy, i.e., the average pore shape and orientation. They are determined by impregnating rocks with ferrofluid and then measuring their magnetic anisotropy. Obtaining ev

Magnetic Pore Fabrics: The Role of Shape and Distribution Anisotropy in Defining the Magnetic Anisotropy of Ferrofluid‐Impregnated Samples
Autor: Andrea R. Biedermann

Pore fabrics define physical properties of a rock, such as permeability and elasticity, both of which are important to many geological, hydrological and environmental applications. Minerals and hence pores are often preferentially aligned, leading to
