Influence Of The Preparation Technique On The Magnetic Characteristics Of Ε-Fe2o3-Based Composites, Dmitriy O. Testov, Kamil G. Gareev, Ivan K. Khmelnitskiy, Andrei Kosterov, Leonid Surovitskii, Victor V. Luchinin

Michigan Tech Publications

ε-Fe2O3 is an iron(III) oxide polymorph attracting an increasing interest due to its unique magnetic properties combining extremely high coercivity and relatively large saturation magnetization. We review existing methods for the ε-Fe2O3 synthesis focusing on synthesis speed, repeatability, manufacturability and purity of the final product. Samples of ε-Fe2O3 have been synthesized using the two methods that appear the most promising: silica gel impregnation and microemulsion. In both cases, ε-Fe2O3 and α-Fe2O3 are present in the final product as attested by X-ray diffraction patterns and magnetic properties (maximum coercive force at 300 K~1 Tesla). Two different precursors, iron(III) nitrate and iron(II) …

Mantle Dynamics Of The North China Craton: New Insights From Mantle Transition Zone Imaging Constrained By P-To-S Receiver Functions, Lin Liu, Stephen S. Gao, Kelly H. Liu, William L. Griffin, Sanzhong Li, Siyou Tong, Jieyuan Ning

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Cratons are generally defined as stable continental blocks with a strong cratonic root that typically is at least ∼200 km thick. Many cratons have undergone little internal tectonism and destruction since their formation, but some of them, such as the eastern part of the North China Craton (NCC), the Dharwar Craton and the Wyoming Craton, have lost their thick cratonic root and become reactivated in recent geological history, leading to widespread Meso-Cenozoic volcanisms. The mechanisms responsible for such decratonization remain debated. To provide new constraints on models leading to decratonization, in this study we stack 612 854 source-normalized P-to-S conversions …

Theses and Dissertations

As the world pushes for ‘greener’ technologies and carbon neutrality, efforts have focused on creating novel ways to mitigate humankind’s carbon footprint. Carbon capture and storage (CCS) has become a prevalent technique that has proven to be an effective long-term method to safely relocate excess carbon dioxide (CO₂) into subsurface formations. However, CCS is a newer technique which requires constant monitoring due to potential leakage pathways present in CO₂ storage sites; therefore, a preventive approach to seal leakage pathways is recommended. This dissertation explores the potential of CO₂-sensitive polyacrylamide (CO₂-SPAM) as a novel …

A Novel Approach To Estimate Rock Strength Parameters From Multistage Triaxial Tests (The A-Has Method), Abo Taleb T. Al-Hameedi, Husam H. Alkinani, Shari Dunn-Norman, Munir Aldin, Sudarshan Govindarajan

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Rock strength parameters are vital to creating robust geomechanical models for wellbore stability, sand production, and hydraulic fracturing. Static rock strength parameters can be estimated from single stage triaxial tests (SST) or multistage triaxial tests (MST). Although SST tests are the most accurate way to estimate rock strength parameters, SST tests require at least four to five core plugs to estimate rock strength parameters. Thus, MST tests are used as an alternative method to estimate rock strength parameters from only one core plug to overcome the limitation of materials and save time and money. However, the currently used method to …
