“…As the charges on the particle increases, the repulsion between the particles increases leading to the increased stability. should be a value between 0 and 2.0 [23], which also confirm that the developed model is suitable for the prediction of thermal conductivity. The final reduced model that predicts the thermal conductivity as a function of mass fraction of nanoparticles and surfactant is given in Eq.…”

“…Desirability function employs dimension reduction strategy in which the multi response model is reduced to a single aggregated measure and then solves it as a single optimisation problem [30]. Moreover this statistical optimisation recommends an optimum operating condition of process parameters that maximises the desirability that range from zero (out of scope) to one (goal) [23]. The condition to obtain an optimised constitute concentration includes the particle concentration to be in range.…”

Augmenting thermal and optical properties of working fluids used in solar thermal conversion systems using hybrid nanomaterials is gaining prominence. In the present study photo-thermal analysis and thermal conductivity investigations were performed on SiO2/Ag-CuO binary water based nanofluid. The influence of particle concentration and surfactant concentration on thermo-optical properties were investigated using the design of experiment concept. Analysis of variance (ANOVA) was employed to study the significance of the process parameters on thermal conductivity and solar weighted absorption fraction of nanofluid. The statistical optimisation of the process parameters was done using the desirability function. The optimum combination of nanoparticles and surfactant that yield good thermal conductivity and solar absorption was found to be SiO2/Ag: 206.3 mg/litre, CuO: 864.7 mg/litre, and SDS (surfactant): 1996.2 mg/litre. The optimum mass fraction of constituents yielded a relative thermal conductivity of 1.234 and solar weighted absorption fraction of 82.82 %.

“…The green chemistry concept can be implemented while producing the proposed membranes for flue gas treatment and REE recovery. During the production of membranes, it is also possible to use, for example, biodegradable biopolymers and ionic liquids, which have pro-ecological properties [47,[97][98][99][100][101][102][103][104][105].…”

“…To modify them, the roasting of coal fly ashes with various reagents, optimization of process parameters, removal of iron oxides, and combination with physical methods have been proposed [38,43]. Because the conventional methods used to recover REEs from obtained extracts have many limitations, some alternative methods based on ionic liquids and membrane techniques were introduced [47]. It was found that the membrane techniques made it possible to achieve REE recovery of over 90%.…”

In this article, the authors present methods based on hard coal that may ensure energy security for European Union countries. The research was carried out based on the example of Poland. The main reason for which coal is being gradually withdrawn from the energy mixes in EU countries is its negative impact on the natural environment and the health of citizens and economic factors related to domestic fuel production. The authors propose the creation of energy–chemical clusters as a solution to these problems. It is assumed that the clusters would operate following the principles of the circular economy. We also propose methods for the optimization of the production and transport costs within the cluster. Then, we conduct profitability analysis of the proposed waste management methods. At the level of the designated cluster, using network algorithms enabled us to reduce the transport costs by at least 50%. It is possible to obtain rare earth elements (REEs) worth USD 22,970 from 1 Mg of ash. At the level of the analyzed cluster, this leads to an annual profit of USD 3.5 billion. The profit related to algae production at the cluster level is approximately USD 2.5 bn.
