Gerhard Ertl Lecture & Award

Gerhard Ertl Lecture & Award

The Ertl Lecture Award was established in 2008 by the three Berlin universities (Humboldt University, Technical University and Free University) and the Fritz Haber Institute of the Max Planck Society and is awarded once a year. It commemorates former FHI Director Gerhard Ertl's Nobel Prize in Chemistry, which he received in 2007. The prize honours outstanding personalities and researchers in the field of catalysis where Ertl carried out exceptional research for many decades. The prize, sponsored by BASF, includes a one-week research stay at the participating Berlin institutions and a keynote lecture. The winner is typically announced in Spring, the lecture takes place around the December 10th, the anniversary of Ertl's Nobel Prize reception.

Nanomaterials with their specific properties for applications in biomedicine and electronics

The content of my lecture are the results of my research carried out in recent years and educational activities on the preservation of molecular matter condensed in nano-systems and their practical applications using their specific properties in biomedicine and electronics. [more]

About the birth, life and death of electrocatalysts for CO2 reduction

Correlating activity, selectivity and stability with the structure and composition of catalysts is crucial to advancing the knowledge in chemical transformations which are essential to move towards a more sustainable economy. [more]

Single-molecule chemistry via noncontact atomic force microscopy: ultrahigh resolution imaging and tip-induced switching

Single-molecule chemistry [1] has progressed together with the development of scanning probe microscopy and its related methods. Scanning tunneling microscopy (STM) has been widelyused for the observation and control of configurational changes and reactions for individual molecules on surfaces. [more]

Ultrafast Science and Technologies at ALLS

The Advanced Laser Light Source (ALLS) is located at INRS-ÉMT near Montreal. It is the national laser facility of Canada offering access to a variety of laser systems and secondary sources. [more]

Water Flows in Carbon Nanochannels, from Carbon Memories to Quantum Friction

The emerging field of nanofluidics explores the molecular mechanics of fluids. This world of infinitesimal fluidics is the frontier where the continuum of fluid dynamics meets the atomic nature of matter, or even its quantum nature. Nature fully exploits the fluidic oddities at the nanoscale and it is capable of breath-taking technological feats using a fluidic circuitry made of multiple biological channels, such as ionic pumps, proton engines, ultra-selective pores, stimulable channels, ...

Understanding of Energy Transfer Dynamics in Luminescent Eu(III) Complex Doped Host-Guest Film

Trivalent europium (Eu(III)) complexes are expected to be used as light-emitting materials such as organic light emitting diodes (OLEDs) because of their high color purity. The complexes are sensitized by the antenna effect, utilizing energy transfer from antenna ligands to a metal center. In the emitting layer of OLEDs, guest emitters are doped in host molecules, and intermolecular energy transfer also occurs. [more]

Lightwave-Driven Scanning Tunneling Spectroscopy for Ultrafast Surface Science on the Atomic Scale

The development of novel nanoscale systems with technologically relevant properties has created a demand for powerful experimental technique’s capable of extreme spatio-temporal resolution. Scanning tunneling microscopy (STM) has become an era-defining surface characterization tool capable of extracting the local density of states (LDOS) with ångström-scale spatial resolution. [more]

Investigating Ultrafast Electron and Phonon Dynamics at the Atomic Scale

Electrons, phonons, and their mutual interactions are crucial for the complex phenomena in strongly correlated materials. In this talk, I will show that electron and phonon dynamics can be investigated at the atomic scale by combining THz pump-probe spectroscopy and a scanning tunneling microscope (STM) [1,2]. [more]

Probing Electronic Structure and Magnetism in Low Dimensionality - An Experimental Approach

The ever-growing need for next-generation electronic and magnetic devices calls for new solutions for the engineering of quantum materials, in terms of miniaturization, energy consumption and speed compared to reference benchmarks, e.g. 18 ps for the Larmor magnetization switching. A new paradigm has emerged: the effect of the decrease of dimensionality in magnetic materials is recently being given a large deal of attention. [more]

Picosecond Interfacial Dynamics in Crowded Lipid Membranes Probed with Ultrafast 2D Infrared Spectroscopy

Lipid membranes are much more than barriers between cell compartments, they are integral components of the cell involved in key functions such as signaling, transport, and sensing. Membranes are composed of hundreds of different lipid species and contain thousands of proteins. The biophysical implications of membrane heterogeneity are not fully understood. Our group uses 2D IR spectroscopy to probe the local hydrogen-bond dynamics at the lipid-water interface. [more]

Collective States in Self-assembled Nanomaterials for New Functionalities in Vibrational Spectroscopy and Light-matter Coupling

Collective states are key to understand properties of materials across different length scales. In my talk, I will give an overview of different functionalities that emerge from collective states, with prospects for vibrational spectroscopy and engineering material properties with light. [more]

Polarons Imaged in Real Space by Combined AFM/STM

Polarons [1] are quasiparticles that form in ionic lattices due to the interaction of excess charges with lattice distortions. This leads to a spatial confinement of the charge and appearance of many novel phenomena. In past decades, polarons turned out to play an important role in electrical transport, optical properties, organic electronics, catalysis, or in exotic materials properties such as colossal magnetoresistance or high-Tc superconductivity.

Fully-atomistic Light-driven Dynamics in Plasmonic Cavities and Interfaces

The study of confined fields in plasmonic nanocavities and their interaction with molecules and nanostructures is an area of research with vast applications, including enhanced spectroscopy techniques as well as photoinduced/photocatalytic non-equilibrium phenomena. From the theoretical perspective, either classical electromagnetic models or atomistic/quantum descriptions are usually considered. However, in many cases these models ignore the electronic and nuclear quantum effects arising from the chemical nature and dynamics of a junction, such as tunneling, adsorption geometry, structure of the interface, vibrations, etc., or include them only approximately. Hence, a full quantum dynamical description is sometimes inescapable. [more]

Structure and Electronic Properties of Ultrathin Indium Films on Si(111)

Ultrathin metal films on atomically flat semiconductor substrates have been of great interest to investigate physical properties of two-dimensional (2D) metals. Indium-adsorbed Si(111) surfaces are one of the most explored metal/semiconductor systems. [more]
