63This method works on the assumption that a molecular set of atoms can be defined by the potential energy, which depends on molecular geometry given by the atoms’ space locations. Potential energy calculations are based on
The definition of Lewis acids is discussed in “Dictionary of Science And Chemistry (the 5th edition)”, for example. Examples of Lewis acids include acid anhydrides, boron compounds and silicon compounds. Examples of acid anhydrides include: alkanesulfonic acid anhydrides the hydrogen elements of ...
Minimisation of Gibbs free energy was used to conduct the chemical equilibrium studies. The CEA (Chemical Equilibrium and Applications) software by NASA [54] was used to perform the thermodynamic equilibrium calculations. All the gaseous reactants (CH4, C2H6, C3H8, N2, CO2 and H2O) and potentia...

The fact that these resources are not energy-dense is typically reflected in their limited economic value. POME is the only liquid and biomass-derived low-grade calorific resource considered in this work, and has potential to be integrated in chemical looping processes. Its high price and ...
Introduction Currently, municipal waste management has emerged as a serious societal issue. In this regard, a challenging issue is the increase in the volume of sewage sludge waste (SS), the treatment of which needs energy-intensive and costly processes and safe disposal methods [1]. The Commiss...
shear-thinning behaviour. The dual effect of the used warm agent and foaming water reduced the viscosity of bitumen by 34.5% at 120 °C. It can, therefore, effectively reduce the rolling temperature of its corresponding asphalt mixture, improving its compaction efficiency and saving energy ...

Introduction Dry-cured ham aging involves the use of textiles to hang the cured meat for 3–24 months to develop the desired flavor. During the...
Figure 2.(a) Scanning electron micrographs of paste-tailing samples, carbon was used as a surface coating (arrows show the different sizes of tailings particles). (b) Energy-dispersive X-ray spectrum of paste-tailing samples. Intensity of Al, Si, Fe, S, and Zn emission lines are shown in...
In essence, process models may be fully derived from first principles (e.g., energy and mass balances), defined as white box models, purely data-driven (black box models), or a combination of both (gray box models) [50]. For Bayesian estimators, the main focus in this article, the ...
