A model for steam gasification of biomass was developed by applying thermodynamic equilibrium calculations. With this model, the simulation of a decentralized combined heat and power station based on a dual fluidized-bed steam gasifier was carried out. Fuel composition (ultimate analysis and moisture content) and the operating parameters, temperature and amount of gasification agent, were varie...

   In the present study, CeO2/Fe2O3 nanocomposite was prepared by co-precipitation method and its application was investigated for arsenic removal from water. Characterization of the nano sized adsorbent particles was carried out using SEM and XRD techniques. Systemic adsorption experiments were performed in batch systems and the optimum conditions were obtained. The effects of p...

In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model. This model is introduced for calculation of the entropy production in a reaction-diffusion system. First, we show the relationship between entropy production and pattern formation, and suggest that the entropy production c...

For a strongly coupled system that has gravity dual description, we show the standard holographic dictionary yields nonnegative susceptibility when is in thermodynamic equilibrium and correlation function absolutely integrable. When no spontaneous condensation or $\mathbb{Z}_2$-symmetry breaking, find ``trace energy condition" violated many cases. There normalized grand potential density monoto...

When spreading onto a protein microlattice living cells spontaneously acquire simple shapes determined by the lattice geometry. This suggests that, on a lattice, living cells' shapes are in thermodynamic metastable states. Using a model at thermodynamic equilibrium we are able to reproduce the observed shapes. We build a phase diagram based on two adimensional parameters characterizing essentia...
