Stress-Induced Depolarization Of Single-Layer Pzt 95/5 Ferroelectric Films,

Stress-Induced Depolarization Of Single-Layer Pzt 95/5 Ferroelectric Films, Sergey I. Shkuratov, Jason Baird, Vladimir G. Antipov, Jay B. Chase, Wesley Hackenberger
Mining Engineering Faculty Research & Creative Works
Ferroelectric (FE) films are widely used in electronic devices and low-power FE transducers. There is significant interest in expanding the usage of FE films to ultrahigh-power systems. The results are reported herein on experimental investigations of stress-induced depolarization of single-layer PbZr0.95Ti0.05O3 doped 2% Nb (PZT 95/5) poled FE films subjected to uniaxial adiabatic compression perpendicular and antiparallel to the direction of polarization. It was found that at a stress of 2.4 GPa, the 32-μm-thick films underwent a pressure induced transition to a nonpolar antiferroelectric phase and became completely depolarized in both modes of high strain …

The contrast in the emissivity spectra of phosphorite and associated carbonate rock can be used as a guide to delineate phosphorite within dolomite. The thermal emissivity spectrum of phosphorite is characterized by a strong doublet emissivity feature with their absorption minima at 9 µm and 9.5 µm; whereas, host rock dolomite has relatively subdued emissivity minima at ~9 µm. Using the contrast in the emissivity spectra of phosphorite and dolomite, data obtained by the thermal bands of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor were processed to delineate phosphorite within dolomite. A decorrelation stretched ASTER radiance composite could …

Investigation Of Properties Alternation During Super-Critical Co2 Injection In Shale, Sai Wang, Kouqi Liu, Juan Han, Kegang Ling, Hongsheng Wang, Bao Jia
Petroleum Engineering Faculty Publications
The low recovery of oil from tight liquid-rich formations is still a major challenge for a tight reservoir. Thus, supercritical CO2 flooding was proposed as an immense potential recovery method for production improvement. While up to date, there have been few studies to account for the formation properties' variation during the CO2 Enhanced Oil Recovery (EOR) process, especially investigation at the micro-scale. This work conducted a series of measurements to evaluate the rock mechanical change, mineral alteration and the pore structure properties' variation through the supercritical CO2 (Sc-CO2) injection process. Corresponding to the time variation (0 days, 10 days, 20 …

Velocity dictates the destructive potential of a landslide. A combination of synthetic aperture radar (SAR), optical, and GPS data were used to maximize spatial and temporal coverage to monitor continuously-moving portions of the Portuguese Bend landslide complex on the Palos Verdes Peninsula in Southern California. Forty SAR images from the COSMO-SkyMed satellite, acquired between 19 July 2012 and 27 September 2014, were processed using Persistent Scatterer Interferometry (PSI). Eight optical images from the WorldView-2 satellite, acquired between 20 February 2011 and 16 February 2016, were processed using the Co-registration of Optically Sensed Images and Correlation (COSI-Corr) technique. Displacement measurements were …

Wall Control Blasting At The Orphan Boy Mine – Butte, Montana, Jewel Sakyi
Graduate Theses & Non-Theses
Blasting is often conducted to produce desirable fragment sizes to minimize production cost and energy consumption in downstream processes, including loading, hauling, and crushing. However, the venting of explosive energy in the rock formation sometimes causes unwanted damage beyond the desired perimeter of the blast area. Control blasting has mainly been used in surface mining operations to minimalize blast damage. To explore the applicability of control blasting in underground mining operations, protect the safety of students, faculty, and staff, prevent overbreak, and to ensure the stability of openings and workings, four experimental control blasts, comprising of three smooth blasts and …

Graduate Theses & Non-Theses
The project discussed in this thesis is part of a larger project developing trees that can tolerate and withstand heavy metals and acidic soils from historic mining operations in Butte Montana as a solution to re-establishing long-term tree growth on those sites. The project involved growing tree seedlings native to Butte, Montana and planting them on degraded mine soils, tailings, and processing wastes (mine waste) located within the Butte Priority Soil Operable Unit (BPSOU). The seedlings were grown for 34 weeks in a greenhouse located on Montana Tech’s campus before being transplanted to a contaminated site (the Clark Mill site) …

The social responsibility of corporate mining has been challenged by a significant socio-political risk from local communities. These issues reduce shareholder value by increasing costs and decreasing the market perception of corporate social responsibility. Community engagement is the process of understanding the behavior and interests of a group of targeted mining communities through surveys and data analysis, with the purpose of incorporating mining community acceptance into the mining sustainability. While mining organizations have discussed community engagement to varying degrees, there are three main shortcomings in current studies, as concluded in the authors' previous research. This paper presents a framework to …
