Migration - N000141210542 -Simulation of Metals in Aggressive Environments
Abstract
Funds are provided to characterize the effect of aggressive environments on metal behavior.The group typically has 4 PhD students, 1 MS student, and 4 undergrads working in the laboratory. The investigator plans to recruit these people in cohorts so that he may teach them more efficiently. Once they join the group, they have committed to working on the theme of Corrosion and Electrochemical Energy Storage. The investigator spends about 6 months to one year meeting with each student ?? hour per week, discussing what specifically they will do for their particular PhD project. He gives them ideas, they go do suggested reading and literature searching and come back the next week. Over time, they arrive at a specific topic. Before the investigator approves the topic, they must convince him that it is viable. The investigator generally wants all students to choose topics that support the work statements of the ONR program. He also encourages students to seek outside support to allow augment ONR support. Thus taken together, the output of our laboratory is strongly supportive of the missions of ONR and specifically the mission of the specific ONR grant.The previous cohort of students worked on several topics:Na+ transport and the design and characterization of membranes that transport ions which is important to understand ion transport in surface films and in separator films of batteries.Catalysis of the oxygen evolution and oxygen reduction processes which are critical in corrosion and in batteries.Simulation of thin film properties and simulation of ion formation properties using advanced molecular dynamicsExperimental characterization of corrosion in situations where the volume of electrolyte is vanishingly small.---important to understanding cracksThe previous cohort of students worked on crack growth measurement of 5083 in various salt concentrations, the effect of polarization and salt solutions on creep, and the simulation of chemical reactions on surfaces. This latter simulation was applied to free electrons in metals to solve the distribution of electrons in a metal in response to surface irregularities and the present of point charges (ions in solution). This was published in Phys Rev B.
