35. A brief history of TPEPICO – and the critical features that make it so powerful

Prof. Tomas Baer (University of North Carolina)

29/09/2014, 08:35

Threshold photoelectron photoion coincidence has evolved during the past four decades into a uniquely powerful tool that is ideally carried out at synchrotron radiation facilities. This talk will combine a bit of history with key experimental features that permit the simultaneous optimization of electron resolution, and electron and ion collection efficiencies. A critical aspect for...

38. Physical chemistry with free electron Lasers (FEL) sources: A prospective view on some experiments and concepts

Dr Gregor Knopp (Paul Scherrer Institute)

29/09/2014, 09:10

Talk

The development of elaborate sustainable and regenerative energy concepts has reached a point at which scientist necessarily have to move beyond macroscopic descriptions and take the steps that enable the ability to probe and decode the microscopic quantum world. Chemical processes, involved in combustion, in atmospheric and in surface science have to be understood on a molecular level, at...

3. A Chemical Kinetics Shock Tube for Synchrotron Studies

Dr Robert Tranter (Argonne National Laboratory)

29/09/2014, 09:30

Talk

In recent years many impressive studies have been conducted at synchrotron light sources using X-rays and VUV photons to probe combustion phenomena from chemical mechanisms in low pressure flames and flow reactors to particle formation in flames. Recent developments promise to bring more synchrotron based diagnostics to bear on combustion studies. However, most practical combustion devices...

13. Multiplexed Synchrotron Photoionization Mass Spectrometric Characterization of Fuel Oxidation Reactions

Prof. Giovanni Meloni (University of San Francisco)

29/09/2014, 10:30

Talk

Multiplexed Synchrotron Photoionization Mass Spectrometry has been demonstrated to be a powerful experimental technique for the observation and characterization of important reaction intermediates, such as peroxy radicals in combustion and Criegee intermediates in atmospheric chemistry, and fuels reaction pathways. In this talk the oxidation reactions, carried out at the Chemical Dynamics...

36. Advances and Challenges in Experimental Research of Combustion

Dr Nils Hansen (Combustion Research Facility, Sandia National Laboratories, Livermore, CA 94551)

29/09/2014, 10:55

Talk

Over the last decade the Chemical Dynamics Beamline at the Advanced Light Source (ALS) of the Lawrence Berkeley National Laboratory has been used extensively to provide unprecedentedly detailed insights into the chemical structure of flames. The isomer-resolved, quantitative data has been used world-wide to update and improve chemical kinetic models for the combustion of hydrocarbon fuels and...

48. Disentangling reactive isomers in flames using PEPICO

Dr Tina Kasper (University of Duisburg-Essen)

29/09/2014, 11:20

Talk

One key aspect to the improvement of combustion devices is the knowledge of how a fuel burns. Flame-sampling molecular-beam mass spectrometry (MBMS) has become a standard technique for chemical analysis of reacting gas flows in premixed laminar low-pressure flames. The MBMS measurements typically result in speciation data that contribute as validation data base to the construction and...

58. International (Photo)-Ionization Cross-section Database

Dr Arnas Lucassen (Physikalisch Technische Bundesanstalt)

29/09/2014, 11:45

Talk

Molecular Beam mass spectrometry has developed into a staple technique for the investigation of gas phase reactive systems including for instance kinetics (Sandia: Kinetics Machine, Univ. Colorado: Reactor, Argonne: Shock tubes), Flow and jet stirred reactors (Princeton, Bielefeld University, NSRL, DLR, Sandia, LBL) and flames (Université catholique de Louvain, Bielefeld University, Princeton,...
