A phase field study of the effect of microstructure grain size heterogeneity on grain growth.
(Rensselaer Polytechnic Institute, Troy, NY, 2017-08)Recent studies conducted with sharp-interface models suggest a link between the spatial distribution of grain size variance and average grain growth rate. This relationship and its effect on grain growth rate was examined ... -
A study of particle generation in sputtering and reactive ion etching of silicon and silicon dioxide
(Rensselaer Polytechnic Institute, Troy, NY, 1993-08)Particle formation in an Ar sputtering plasma and a reactive ion etching plasma of CCl2F2/Ar was investigated using silicon and silicon dioxide substrates. -
Accelerated electromigration study in cobalt by novel in-situ tem technique
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)Electromigration is a phenomenon in which electronic conduction can result in mass transport of the conducting material, resulting in the eventual failure of a device. Momentum transfer from the conducting species to the ... -
Aligned titania nanotube array thin films: growth kinetics, branched structures, and photovoltaic characterization
(Rensselaer Polytechnic Institute, Troy, NY, 2011-08) -
AlN, ScN, and Al-Sc-N ternary alloys : structural, optical, and electrical properties
(Rensselaer Polytechnic Institute, Troy, NY, 2013-12)For the purpose of achieving tilted c-axis texture in AlN, off-axis deposition is temperature. XRD pole figure analysis show that layers deposited from a normal angle (α = 0°) exhibit fiber texture, with the c-axis tilted ... -
An analysis of the drawing of hexagonal bar from round stock

Application of the phase field model towards selective laser melting of Inconel 718, through an integrated multiscale framework
(Rensselaer Polytechnic Institute, Troy, NY, 2021-12)The Selective Laser Melting (SLM) process is a developing additive manufacturing process for metals. This technique allows for very fine details to be produced with minimal post-processing required, and is especially useful ... -
Bias in polycrystal topology caused by grain boundary motion by mean curvature
(Rensselaer Polytechnic Institute, Troy, NY, 2015-05)During heat treatment of polycrystalline materials, grain shape affects the rate of grain growth. In 2-D, the von Neumann-Mullins Law requires grains with fewer than six edges to shrink, greater than six edges to grow, and ... -
Centrifugal jet spinning of polymer nanofiber assembly : process characterization and engineering applications
(Rensselaer Polytechnic Institute, Troy, NY, 2014-12)High surface area together with unique electrical, thermal, and mechanical properties makes polymer nanofibers suitable in various commercial sectors, including but not limited to electronics, energy, mechanical/chemical, ... -
Characterizing Creatinine MIP Functionality Using Spectroscopy Techniques
(Rensselaer Polytechnic Institute, Troy, NY, 2021-12)The availability and timely use of novel diagnostic tools often benefits the prognosis and progression of many common diseases, including chronic and acute kidney disease, through better allotment of scarce treatment ... -
Chromium ion implantation of In625 for in-situ tem molten chloride salt corrosion
(Rensselaer Polytechnic Institute, Troy, NY, 2022-12)Concentrated Solar Power plants (CSP) capture the Sun's thermal energy by concentrating sunlight to a central tower which transfers the heat to a thermal energy storage material (TES) such as molten salts. The TES containers ... -
