“…Also, the efficiency of the process may be enhanced by using addition technologies such as waste catalysis [26,27], the use of nanoparticles [28][29][30][31][32][33][34][35] to provide additional purification. In addition optimization could be reached by using modern decision-making tools such as ontologies [36][37][38][39].…”

This scientific paper provides an analysis of the current state of biogas production and potential for improvement through optimizing biogas production and diversifying production. The analysis uses data from open sources and reports, such as EBA’s Statistical Report and analytical reports on market and digestate analysis. The authors present a comparison of electricity costs and biogas plant distribution in Europe, confirming that the higher the cost of electricity, the more widespread the introduction of biogas plants as an alternative energy source. The paper also discusses the potential of green ammonia production during anaerobic digestion, which can increase the efficiency and sustainability of biogas production technologies. The innovative technology of ammonia production from livestock waste during anaerobic treatment reduces the amount of water needed for dilution and transforms dissolved ammonia, which is toxic for anaerobic fermentation, into a useful final product. The paper highlights the potential for economically attractive approaches that use existing infrastructure and can contribute to energy independence and sustainability. The authors conclude that optimization in terms of more optimal process conditions and diversification of production approaches can increase the sustainability of biogas production technologies and ensure broader use.

For the first time the possibility of the complex nanodispersed compound formation at mechanochemical and sonochemical treatment of the initial compounds mixture was shown. Mechochemical treatment of the mixture of molybdenum oxide and bismuth nitrate permits to obtain of bismuth molybdate in form of nanoparticles, in the same time the treatment of mixture of titanium oxide and calcium hydroxide leads to formation of calcium titanate in form of nanoprisms. It was shown that mechanochemical treatment of the mixture of titanium oxide and tin oxide leads to formation of titanium oxide amorphous layer on tin oxide surface. The mechanism of nanodispersed zinc molybdate formation at sonochemical treatment of initial oxides was established. It was shown that nanocomposites synthesized by these methods demonstrate the higher catalytic activity in organic compounds neutralization processes in water solutions at visible light irradiation and in the process of bioethanol selective oxidation to acetaldehyde and hydrogen in comparison with known analogous catalysts synthesized by traditional methods.

“…The size of nanoparticles is generally limited to less than 100 nm. They are different from macroscopic bulk structures and have small size effects, surface effects, quantum size effects, and macroscopic quantum tunneling effects [ 14 ]. Nanomaterials are often combined with carriers with slow release and degradable embedding.…”

Titanium dioxide nanoparticles (nTiO2) are widely used as fertilizers in agricultural production because they promote photosynthesis and strong adhesion. Low pollination and fertilization due to rainy weather during the litchi plant’s flowering phase result in poor fruit quality and output. nTiO2 would affect litchi during the flowering and fruiting stages. This study considers how nTiO2 affects litchi’s fruit quality and pollen viability during the flowering stage. The effects of nTiO2 treatment on pollen vigor, yield, and fruit quality were investigated. nTiO2 effectively improved the pollen germination rate and pollen tube length of litchi male flowers. The germination rate reached 22.31 ± 1.70%, and the pollen tube reached 237.66 μm in the 450 mg/L reagent-treated group. Spraying with 150 mg/L of nTiO2 increased the germination rate of pollen by 2.67% and 3.67% for two types of male flowers (M1 and M2) of anthesis, respectively. After nTiO2 spraying, the fruit set rates of ‘Guiwei’ and ‘Nomici’ were 46.68% and 30.33%, respectively, higher than those of the boric acid treatment group and the control group. The edibility rate, titration calculation, and vitamin C of nTiO2 treatment were significantly higher than those of the control. The nTiO2-treated litchi fruit was more vividly colored. Meanwhile, the adhesion of nTiO2 to leaves was effectively optimized by using ATP and BCS to form nTiO2 carriers and configuring nTiO2 complex reagents. These results set the foundation for future applications of titanium dioxide nanoparticles as fertilizers for agriculture and guide their application to flowers and fruits.
