Temperature-dependence Of Stress-related Phenomena
(Materials Science & Engineering, 2014-07-14)Efforts have been made to develop a simple but physically sound model. The model was specifically proposed to capture, explain, and estimate the temperature sensitivity and strengthening mechanism phenomena in small volume ... -
Templated Synthesis And Characterizations Of High Moment Magnetic Nanoparticles For Bioapplications
(Materials Science & Engineering, 2011-07-14)Magnetic nanoparticles have been widely used for biomedical applications such as drug and gene delivery, hyperthermia treatment of cancer, MRI contrast enhancement, cell labeling and magnetic separation. We present two new ... -
THE CHARACTERIZATION OF SECONDARY LITHIUM-ION BATTERY DEGRADATION WHEN OPERATING COMPLEX, ULTRA-HIGH POWER PULSED LOADS
(2016-09-12)The US Navy is actively developing all electric fleets, raising serious questions about what is required of onboard power supplies in order to properly power the ship’s electrical systems. This is especially relevant when ... -
The Effects of SnAgCu Solder Interconnect Package’s Parameters on Electromigration Failure Mechanisms
(2021-12-17)The primary concern of this dissertation is the electromigration (EM) failure mechanism found in Sn-Ag-Cu (SAC) solder alloys integrated in WCSP (wafer-level chip scale package) packaging structure and factors affecting ... -
Thermal Failure Mechanism And Voltammetry Metrology For Cu/barrier/low K Integration
(Materials Science & Engineering, 2007-08-23)The present study investigates the thermal stability of Cu/barrier/porous low κ (PLK) integration first, and then a new characterization method based on voltammetry is developed to characterize quality of diffusion ... -
Tribological And Antiwear Mechanisms Of Fluorinated Zinc Dialkyl Dithiophosphate In Comparison To Zinc Dialkyl Dithiophosphate In Engine Oils
(Materials Science & Engineering, 2008-08-08)Tribofilms generated in wear tests using lubricants containing fluorinated ZDDP and ZDDP were studied. Fluorinated ZDDP demonstrated superior wear performance compared to ZDDP under tribological conditions even at lower ... -
Tribological Performance Of Ashless Antiwear Additives Under Extreme Pressure Conditions
(Materials Science & Engineering, 2010-07-19)Zinc diakyl dithiophosphate (ZDDP) has been used in engine oil for several decades as an antiwear additive. However, ZDDP is the primary source of P, S and Zn in the exhaust, which results in frequent maintenance or ...
