An off-lattice kinetic Monte Carlo method for the investigation of grain boundary kinetic processes
(Massachusetts Institute of Technology, 2016)Kinetic Monte Carlo (Kc) methods have the potential to extend the accessible timescales of off-lattice atomistic simulations beyond the limits of molecular dynamics by making use of transition state theory and parallelization. ... -
On the electrolytic nature of molten aluminum and rare earth oxides
(Massachusetts Institute of Technology, 2018)The electrolytic cell method and its application for Gibbs energy measurement in high temperature, concentrated ionic melts was investigated. Previous challenges related primarily to signal interpretation during decomposition ... -
Once upon a sheep : a SEM analysis of ovine patellar enthesis
(Massachusetts Institute of Technology, 2012)In tendon injury repair, the insertion of the tendon into the bone or enthesis often determines the quality of healing and poor enthesis often leads to treatment failure. However, natural enthesis is not very well understood ... -
Operational and policy implications of managing uncertainty in quality and emissions of multi-feedstock biodiesel systems
(Massachusetts Institute of Technology, 2012)As an alternative transportation fuel to petrodiesel, biodiesel has been widely promoted within national energy portfolio targets across the world. Early estimations of low lifecycle greenhouse gas (GHG) emissions of ... -
Operational sustainability metrics : a case of electronics recycling
(Massachusetts Institute of Technology, 2005)In the past 15 years corporations and governments have developed a growing appreciation of the need for "sustainability" and have worked the term into their goals, strategy and mission statements. Despite extensive efforts ... -
Optical absorption of bismuth silicon oxide (Bi₁₂SiO₂₀) crystals
(Massachusetts Institute of Technology, 2001)The purpose of this work is to characterize the optical absorption in bismuth silicon oxide (Bi₁₂SiO₂₀) crystals grown using the Bridgman technique and to identify electronic transitions responsible for absorption. Optical ... -
