Profile

Dr. Yamada is a Senior Research Scientist in UDRI's Kinetics and Process Engineering group. He has over 20 years of experience in Environmental, Combustion, and Renewable Energy fields. He is highly experienced in both Experimental and Computational studies, and deals with a wide range of research from basic to applied, from ab initio Molecular Orbital (MO) calculations and Molecular Dynamics (MD) simulations to pilot- and commercial-scale system design and development.

He manages multiple projects funded by both government agencies and private sector businesses. Government agencies include the Department of Defense (DoD), Department of Energy (DoE), National Science Foundation (NSF), Environmental Protection Agency (EPA), and Ohio Coal Development Office (OCDO). Private sector businesses include many Fortune 500 companies in chemical production.

Research

  • Fuel Desulfurization Process --- Familiar with both Hydrodesulfurization (HDS) and Oxidative Desulfurization (ODS). Recently successfully achieved reduction of a sulfur concentration from 2000 ppm to fewer than 15 ppm using ODS process.
  • Application of Ozone (O3) Microbubble (MB) Technology --- Recently demonstrated the effectiveness of O3 MB technology to treat microorganisms in water. Also demonstrated O3 MB’s capability to decompose organic pollutants.
  • Low Cost Electrolyzer Development --- Successfully developed low cost alkaline electrolyzer to generate hydrogen at 2.5 kg/day (~21 L/min.) rate at over 70% energy efficiency.
  • Aircraft Paint Stripping Process --- The chemical paint stripping mechanism by major solvents was successfully elucidated by experiment and ab initio Molecular Orbital (MO) calculation, and potential environmentally benign chemicals were proposed.
  • Incineration Byproduct Analysis --- Using System for Thermal Degradation Studies (STDS), incineration byproduct analysis study was conducted at UDRI for more than 20 years. Numerous Fortune 500 companies requested we analyze the off-gas when their products are incinerated.
  • Computational Gas-Surface Reaction Study --- Using VASP Density Functional Theory (DFT) package and ReaxFF Force Fields, the reaction mechanisms and their rate of formaldehyde decomposition on Iron surface was successfully elucidated. The computational method established in this study can be applicable for other gas-surface reaction study.
  • Reaction Kinetics Studies Using Laser Photolysis – Laser Induced Fluorescence (LP-LIF) technique and ab initio Computational Approach --- Reaction kinetics of OH radical with a number of organic compounds were studied using LP-LIF technique. The reaction rates were also derived by ab initio MO calculations and Transition State Theory (TST), and the results were compared with experimental results.
