The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Plinio Maroni, Michal Borkovec, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...

Dispersion Characteristics and Aggregation in Titanate Nanowire Colloids

László Forró, Plinio Maroni, Arnaud Magrez, Endre Horvath

Titanate nanowires (TiONWs) are synthesized through the hydrothermal method and characterized in acidic aqueous dispersions by using electrophoresis, dynamic light scattering, and atomic force microscopy. The TiONWs have a rodlike shape with an average len ...

State-Resolved Reactivity of CH4(2ν3) on Pt(111) and Ni(111): Effects of Barrier Height and Transition State Location

Rainer Beck, Plinio Maroni, Thanh Tung Dang, Marco Sacchi, Régis Bisson, Bruce Yoder

Quantum state-resolved sticking coefficients on Pt(111) and Ni(111) surfaces have been measured for CH4 excited to the first overtone of the antisymmetric C-H stretch (2ν3) at well defined kinetic energies in the range of 10-90 kJ/mol. The ground state rea ...

Efficient Stimulated Raman Pumping for Quantum-State Resolved Surface Reactivity Measurements

Thomas Rizzo, Rainer Beck, Plinio Maroni

We describe the use of stimulated Raman pumping in a molecular beam to perform quantum state resolved gas-surface reactivity measurements for molecules prepared in totally symmetric vibrational states. Vibrational states of homonuclear diatomics as well as ...

State-resolved gas-surface reactivity of methane in the symmetric C-H stretch vibration on Ni(100)

Thomas Rizzo, Rainer Beck, Plinio Maroni, Thanh Tung Dang, Marco Sacchi

The state-resolved reactivity of CH4 in its totally symmetric C-H stretch vibration (nu(1)) has been measured on a Ni(100) surface. Methane molecules were accelerated to kinetic energies of 49 and 63.5 kJ/mol in a molecular beam and vibrationally excited t ...

Bond- and mode-specific reactivity of methane on Ni(100)

Plinio Maroni

In this work, the state-resolved reactivity of methane excited to different C-H stretch vibrations have been measured on a Ni(100) surface. Two kinds of experiments have been performed. In the first series of experiments, we have measured the reactivity of ...
