  • KCC Seminar: Solving Reaction Mechanisms in Batteries and Electrocatalysts using Combined Soft and Hard X-ray based XAFS under Operando and In/Ex-situ Conditions

    Dec 21 2017 10:00 AM - Dec 21 2017 10:00 AM Dr. Faisal M. Alamgir
    School of Materials Science and Engineering
    Georgia Institute of Technology

    Core-hole based X-ray spectroscopies used under ex situ, in situ and operando conditions provide information vital to unraveling the mechanisms of charge transfer and structural re-organization of electrochemical materials. In this presentation, we will specifically look at how the core-hole techniques of X-ray absorption can be used in the study of electrochemically active materials such as in batteries and fuel cells, particularly by tuning to resonances in both the soft and hard x-ray regimes.
    First we will examine the role of oxygen in the charge compensation of LiMO2 compounds and the consequences of such for battery safety and for unprecedented changes to electrical/magnetic properties. The electronic and atomic structure local to oxygen was first examined indirectly using hard x-rays by operando resonant K-level measurements of M atoms in battery cathodes of working batteries. The results were then complemented by direct operando measurements at the K-edge of oxygen atoms in the cathode using soft x-rays. It will be demonstrated that the detailed electrochemical roadmap for the reaction mechanisms in LiMO2 cathodes could only be revealed by a combination of soft and hard x-ray based experiments. Next, we will look at the effects of dimension, strain and charge transfer on the electrochemical activity and durability of electrocatalysts for both low and high temperature fuel cells. Again, it will be demonstrated that a thorough employment of XAFS and its complementary core-hole methods at both soft and hard x-ray regimes is necessary to reveal a detailed story of the reaction mechanisms in working electrocatalysts.

  • KCC Seminar: Enhancing carrier dynamics in metal oxide photoelectrodes through defect control and passivation

    Nov 12 2017 03:00 PM - Nov 12 2017 05:00 PM Dr. Fatwa F. Abdi
    Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Institute for Solar Fuels, Hahn-Meitner-Platz 1, Berlin 14109, Germany

    Metal oxides are attractive photoelectrode materials for photoelectrochemical (PEC) water splitting, due to their aqueous stability and low cost. However, high efficiency is still hindered by the fact that metal oxides possess relatively poor carrier transport properties (i.e., carrier mobility and lifetime). To illustrate this, carrier mobilities can be as high as 8,500 and 1,500 cm2/Vs in GaAs and Si, respectively,[1] while values of ~0.01-0.1 cm2/Vs are typically observed for metal oxide photoelectrodes (e.g., Fe2O3 and BiVO4).[2-4] Carrier lifetimes are also relatively short, in the range of pico- to nano-seconds.[4,5] In this talk, efforts in enhancing the carrier transport properties in metal oxides by controlling the defects—both intrinsic and extrinsic—in the lattice will be discussed. Examples will be shown based on the development of BiVO4 photoanodes, which is one of the highest performing metal oxides for solar water oxidation. First, by exposing as-deposited BiVO4 to high temperature treatment under different atmosphere, we found that the concentration of intrinsic defects (e.g., oxygen and vanadium vacancies) can be modulated. An optimum heat treatment condition resulted in an increase of carrier mobility by as high as one order of magnitude, as evident from our time-resolved conductivity measurements. Although the carrier lifetime was slightly decreased, the overall diffusion length increased by a factor of ~2. Second, extrinsic defects (i.e., dopants) were also found to greatly influence the carrier transport properties of BiVO4: (i) tungsten decreases both carrier lifetime and mobility,[4] (ii) hydrogen increases carrier lifetime and does not affect the carrier mobility,[6] while (iii) sulfur has no effect on carrier lifetime but increases carrier mobility. The exact causes behind these differences (e.g., defect passivation, trapping) will be discussed. Finally, the interplay between these modifications of carrier transport properties to the PEC properties of BiVO4 will be elucidated.

  • KCC Seminar: Difference between iron and ruthenium catalysts for ammonia synthesis

    May 15 2017 10:00 AM - May 15 2017 11:30 AM Prof. Ken-ichi Aika
    Professor Emeritus, Tokyo Institute of Technology

    Ammonia synthesis is one of the most established and mature chemistries in heterogeneous catalysis from both academic and industrial point of views. Ammonia is one of the CO2 free hydrogen carriers and can be used as the direct fuels. The presentation describes how ammonia is important in current society, how the catalyst has been established in the history, and reaction mechanisms have been investigated and discussed in the laboratory scale and translated into industrial scale. Iron and ruthenium catalysts are effectively compared and the essential role of promoter is introduced.

    The lecture is devoted to late Prof. Atsumu Ozaki

  • KCC Seminar: Designer Zeolites: better, smaller, more accessible and… cheap

    May 14 2017 12:00 PM - May 14 2017 01:00 PM Prof. Jean-Pierre Gilson
    Laboratoire Catalyse & Spectrochimie (LCS)


    Zeolites are still fast growing materials, 55 years after their revolutionary introduction in oil refining and petrochemistry. I will concentrate on the "Zeolite Crystal Engineering", i.e. the fine tuning of the properties of known zeolites to meet exacting requirements of modern processes. I will describe fundamental work on nucleation that opened the door to the preparation of inexpensive, template-free, nanosized FAU (X & Y variety) with outstanding catalytic performances. I will describe other fundamental studies on the controlled removal of defects in existing zeolites that lead also to vastly superior catalysts and probably adsorbents. Finally, I will discuss the so-called embryonic zeolites, probably the last frontier between organized and disorganized materials and touch a bit the understudied but critical topic of the chemical interactions between a zeolite and its binder during a shaping process (e.g. extrusion).​

  • KCC Seminar: Thermodynamics and kinetics of drug-target binding through molecular simulations

    May 11 2017 01:30 PM - May 11 2017 02:30 PM Prof. Andrea Cavalli
    University of Bologna and Italian Institute of Technology, Italy

    Drug-target binding represents the first event at the basis of the therapeutic action of drugs. This complex phenomenon needs to be properly described at an atomistic level to identify the major determinants of drug potency and in vivo drug efficacy. Molecular dynamics (MD) is emerging as a powerful tool for investigating protein-ligand binding, and is getting increasing consensus from the drug discovery community. While extensive MD simulations in the microsecond to the millisecond timescale are nowadays able to simulate protein-ligand binding “spontaneously”, enhanced sampling methods, including metadynamics, steered-MD, umbrella sampling, etc., can improve the sampling of that part of free energy landscape that can be relevant for the biological process under investigation.
    In this talk, I will be presenting the use of extensive MD simulations to investigate spontaneous protein-ligand binding. Then, I will show how free energy calculations allow the identification of the minimum free energy path from the bulk of the solvent into the protein-binding pocket, as well as the determination of thermodynamic and kinetic parameters associated to drug-target recognition and binding. The presentation will finally be focused on applications of enhanced sampling methods to accelerate ligand binding and unbinding and to estimate kinetics (kon and koff) and thermodynamics, in simulation timescale more compatible with the requirements of speed and accuracy of the pharmaceutical research. All these simulations will be discussed in the framework of drug design and discovery, highlighting the role of these approaches in real-life drug discovery endeavors.

    ABSTRACT: The chemistry of monovalent phosphorus has known recently a huge development thank to the discovery of simple and versatile methods to generate [RP-W(CO)5]. These tungsten complexes have a singlet ground state contrary to the free species which are triplets. The complexes mimic the chemistry of singlet carbenes. Recent developments include their reaction with boronic acids to create P-C bonds, insertion into P-H bonds to create P-P bonds and regioselective insertion into appropriate C-H bonds.
