Hiden Analytical DEMS Conference at Pennsylvania State University
A Short History of Hiden DEMS: From Poitiers to Penn State
Jim Melling, Hiden Analytical: Jim is Senior Applications Specialist for Gas Analysis at Hiden UK – specializing in multi fermenter biogas, syngas analysis, membrane inlet MS and of course DEMS and OEMS. He also advises on software development and cross system integration.
Insights into the Electrochemical Reduction of Carbon Dioxide with Differential Electrochemical Mass Spectrometry
Professor Ezra Clark, Penn State University: Ezra is the Thomas K. Hepler Early Career Professor of Chemical Engineering at the Pennsylvania State University. His research group focus on the development of electrocatalytic technologies for sustainable fuel and chemical production. Currently, his group is focused on the development of electrochemical isotopic transient measurements, the design of intermetallic electrocatalysts, and the exploration of thermo-electrocatalytic synergy.
Elucidating the Origins of Electrocatalytic Phenomena using Steady State Isotopic Transient Kinetic Analysis
Abigail R. Circelli, Penn State University: Abby is a fourth-year chemical engineering graduate student at Penn State University, advised by Prof. Ezra Clark. Abby’s doctoral thesis focuses on fundamental electrocatalytic activity measurements.
Dynamic Electrochemistry: Unraveling Electrochemical Processes with In-Situ DEMS
Dr. Moon Park, Argonne National Laboratory on behalf of Professor Mohammad Asadi. Illinois Institute of Technology, Chicago: Dr. Park’s research interests include fundamental understandings of materials science and electrochemical reactions such as oxygen reduction (ORR), oxygen evolution (OER), and hydrogen evolution reactions (HER) on electrocatalyst materials applied in non-aqueous Li-Oxygen batteries, aqueous Zn-air batteries, and water electrolysis system. Prof. Asadi’s research interests are experimental studies of surface chemistry in catalytic and electrocatalytic reactions, electrochemical energy storage (e.g., metal-ion and metal-air batteries) and energy conversion (e.g., CO2 reduction reaction) systems as well as design, synthesis, and characterization of advanced materials for energy-related applications.
Enhanced calibration techniques and design considerations for accurate differential electrochemical mass spectrometry (DEMS)
Mark Kazour, Sietz Group, Northwestern University, Illinois: Mark is a third-year graduate student in Professor Linsey Seitz’s lab at Northwestern University. His research focuses on halogen-mediated styrene epoxidation with antimonate catalysts for the chlorine evolution reaction as well as hydrogen peroxide production in a membrane electrode assembly.
Theoretical and practical considerations for rigorous on-line mass spectrometry for electrochemical kinetics
Todd Whittaker, University of Colorado, Boulder: Todd is a 5th year PhD student at the University of Colorado Boulder, working under the supervision of Professor Adam Holewinski. His research has primarily focused on developing a deeper connection between computational and experimental techniques in electrocatalysis, specifically as it relates to mechanism discrimination.
Laboratory Demonstration
Prof. Ezra Clark and Abigail R. Circelli, Penn State University: Ezra talks us through the DEMS technique and Abby gives us a lab tour and demonstrates the Hiden Analytical HPR-40 DEMS instrument and applications.
