Water at Interfaces

Gabriele Tocci, Martin Hangaard Hansen, Eric Tyrode

The interfaces of neat water and aqueous solutions play a prominent role in many technological processes and in the environment. Examples of aqueous interfaces are ultrathin water films that cover most hydrophilic surfaces under ambient relative humidities ...

H2O2 generation at carbon paste electrode with decamethylferrocene solution in 2-nitrophenyloctyl ether as a binder. The catalytic effect of MoS2 particles

Hubert Girault

Here, we report hydrogen peroxide generation at 2-nitrophenyloctyl ether (NPOE)-water interface with decamethylferrocene as an electron donor. The progress of this reaction was detected by the observation of color change of the organic and aqueous phases i ...

A TEM study of Ni interfaces formed during activation of SOFC anodes in H 2 : Influence of grain boundary symmetry and segregation of impurities

Jan Van Herle, Cécile Hébert, Aïcha Hessler-Wyser, Quentin Thomas Jeangros

The electrochemical properties of a solid oxide fuel cell depend on many parameters, including – on the anode side – the connectivity of the Ni network and the segregation of impurities at active points. In this work, advanced scanning transmission electro ...

Model for charge/discharge-rate-dependent plastic flow in amorphous battery materials

William Curtin, Seyed Mostafa Khosrownejad

Plastic flow is an important mechanism for relaxing stresses that develop due to swelling/shrinkage during charging/discharging of battery materials. Amorphous high-storage capacity Li-Si has lower flow stresses than crystalline materials but there is evid ...

Modeling of Ion Crossover in Vanadium Redox Flow Batteries: A Computationally-Efficient Lumped Parameter Approach for Extended Cycling

Christopher Raymond Dennison

In this work, we have developed a zero-dimensional vanadium redox flow battery (VRFB) model which accounts for all modes of vanadium crossover and enables prediction of long-term performance of the system in a computationally-efficient manner. Using this m ...
