THE MORK FAMILY DEPARTMENT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCE PRESENTS A SEMINAR
BYProfessor Adri van Duin Materials and Process Simulation Center, Beckman Institute
Caltech, Pasadena, CAA transferable computational method for atomistic-scale dynamical simulations of chemical reactionsAbstractCoupling the structures, compositions, and properties at the atomistic level to predictions of macroscopic properties and processes provides an enormous technical challenge for computational chemistry, physics, materials science, and engineering. This lecture will provide an overview of the applications and background of the ReaxFF reactive force field, which provides a method for incorporating chemical reactions in atomistic simulations. ReaxFF is a bond-order dependent force field method that includes a geometry-dependent polarizable charge distribution, allowing reactive, atomistic scale dynamic simulations at a computational expense magnitudes lower than quantum mechanical (QM) simulations. While initially developed for first-row elements, over the last years we found the method to be highly transferable, allowing us to develop ReaxFF descriptions for covalent, metallic, ionic and mixed systems all across the periodic system.Ongoing projects involving ReaxFF include:- Reactions on Ni/Pt/Ru anodes and cathodes in fuel cells
- Hydrogen and oxygen transfer through fuel cell electrolytes
- Carbon deposition and nanotube growth catalyzed by transition metals
- Hydrogen storage in magnesium and magnesium fluorides
- Stress-induced cracking in silicon and aluminium oxides
- Temperature and chemistry-induced failure of silicon polymers
- Nitramine and peroxide-based high-energy material sensitivity
- Energy release of nitramine/metal/metal oxide composite materials
- Enzyme catalysis
- Iron melting at the temperatures and pressures of the Earth's core
- Dielectric breakdown in silicon-based semiconductors
-This lecture will address the highlights from this research and will discuss the concepts behind ReaxFF and its relation to other computational simulation methods, including its implementation in a multiscale simulation environment (CMDF) that allows coupling of different length- and time scales.

The Enduring Consequences and Lesons of the Chernobyl Accident
Fri, Sep 30, 2005 @ 01:00 PM - 02:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Professor Najm Meshkati
Department of Civil & Environmental Engineering
Viterbi School of Engineering
University of Southern CaliforniaAbstractIn the early morning hours of 26 April 1986, a testing error caused an explosion at the reactor number 4 at the Chernobyl nuclear power station in northern Ukraine. The major consequences of Chernobyl fall into three categories: the physical impacts, in terms of health and environmental effects; the psychological and social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide. This accident caused a radioactive fire that burned for 10 days, releasing 190 tons of toxic materials into the atmosphere. The wind blew 70% of the radioactive material into the neighboring country of Belarus and the rest of the world, causing twenty-three percent (23%) of prime Belarusian farmland to become and to this day remains dangerously contaminated. At the time of the accident, about 7 million people lived in the surrounding area.According to a most recent speech on September 6, 2005, by Dr. Mohamed ElBaradei, the Director General of the UN's International Atomic Energy Agency, "the first lesson that emerged from Chernobyl was the direct relevance of international cooperation to nuclear safety" and "nuclear and radiological risks transcend national borders -- that an accident anywhere is an accident everywhere." This presentation covers consequences and lessons of the Chernobyl accidents for the world's nuclear industry. Professor Meshkati, through an invitation from the United Nations, inspected and spent time in the control room of the only operating reactor (No. 3) of the Chernobyl in May 1997, studied the Sarcophagus and its environmental health hand safety problems for the EBRD, and visited the Exclusion Zone and the (deserted, ghost) town of Pripyat.
