The optimal control problem for the hydrogen evolution reaction (HER) system is posed for different cost objectives and admissible control strategies. The solution for the set-point-change process is given in analytical ...

Dos operadores de escalera se introducen  para resolver la ecuación radial del átomo de hidrógeno. Los valores propios de energía, así explícitas expresiones analíticas para las funciones propias de este problema particular, ...

In this work, a COPrOx monolithic reactor with a CuO/CeO2/Al2O3 catalytic washcoat was modelled to purify a H2 stream for a 2 kW PEM fuel cell. Preliminary simulations included isothermal monoliths operating between 423 ...

A molecular theory is introduced to model the layer-by-layer self-assembly (LbL-SA) of polymers with pairing interactions. Our theory provides a general framework to describe nonelectrostatic LbL-SA as the pairing interactions ...

A generalized kinetic model resulting from several modifications of the one originally known as the Series Event Model has been applied to describe three different disinfection processes and compare their efficiencies. The ...
