Orientational ordering of water in extended hydration shells of cations is ion-specific and is correlated directly with viscosity and hydration free energy

Yixing Chen, Sylvie Roke, Halil Ibrahim Okur, Chung-Wen Liang

Specific ion effects in aqueous solutions are investigated at the molecular, nanoscopic and macroscopic levels. Femtosecond elastic second harmonic scattering (fs-ESHS) is used here to assess the chemical effects of ions on molecular and nanoscopic length ...

Solvent fluctuations and nuclear quantum effects modulate the molecular hyperpolarizability of water

Michele Ceriotti, Sylvie Roke, David Mark Wilkins, Andrea Grisafi, Gabriele Tocci, Chung-Wen Liang

Second-harmonic scattering (SHS) experiments provide a unique approach to probe noncentrosymmetric environments in aqueous media, from bulk solutions to interfaces, living cells, and tissue. A central assumption made in analyzing SHS experiments is that ea ...

Electrolytes induce long-range orientational order and free energy changes in the H-bond network of bulk water

Michele Ceriotti, Sylvie Roke, Carlos Alberto Macias Romero, Yixing Chen, Halil Ibrahim Okur, David Mark Wilkins, Gabriele Tocci, Chung-Wen Liang, Nikolaos Gomopoulos

Electrolytes interact with water in many ways: changing dipole orientation, inducing charge transfer, and distorting the hydrogen-bond network in the bulk and at interfaces. Numerous experiments and computations have detected short-range perturbations that ...

Second-Harmonic Scattering as a Probe of Structural Correlations in Liquids

Michele Ceriotti, Sylvie Roke, David Mark Wilkins, Gabriele Tocci, Chung-Wen Liang

econd-harmonic scattering experiments of water and other bulk molecular liquids have long been assumed to be insensitive to interactions between the molecules. The measured intensity is generally thought to arise from incoherent scattering due to individua ...

Concept and technology of SOFC for electric vehicles

Raphaël Ihringer, Jan Van Herle, Chung-Wen Liang

A SOFC concept based on microtubular cells is presented. Mechanical tests and modelling show viability for fast thermal cycling in air for both zirconia and ceria electrolyte tubes. To combine advantages of both these materials, the concept includes a thin ...
