Natural gas is extracted from the subsoil which is not a renewable source, however, the dominance of this product in the international market is significantly higher in future. It reflects the global view of renewable sources (biogas) and hinders the sustainable development of bioenergy. It describes the major issues and trends in the development of biogas industry, paying special attention to current biomass upgrading technologies, methane activation for fuel production and model compounds investigation. The conducted research gives reason to believe that the valorization of organic waste generated worldwide during the production of biomethane that can potentially satisfy. No more than one fifth of global demands for natural gas due to technical difficulties and economic constraints associated with the purification of biogas. The existing production potential of biogas production is focused on obtaining biomethane and high growth rates of demand for biohydrogen. A pressing need arises the possibilities for further development of biogas industry lie in optimizing the biomethanation processes, which allows to reduce the costs of biogas modernization system and decreasing the negative effect on climate changes by replacing petrochemical derived fuels with biofuels in various sectors of economy.

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...

Blue QLEDs face a critical challenge in balancing high luminous efficiency with operational stability, primarily due to uncontrolled electron injection and interfacial trap-assisted recombination. Here, we present a facile aqueous ZnCl2 post-treatment strategy to engineer ZnMgO (ZMO) electron transport layers (ETLs). This approach leverages a synergistic mechanism of hydrolysis-induced recrystallization and chloride-mediated surface passivation to transform ...

Wide-bandgap (WBG) perovskites used in monolithic tandem solar cells are limited by nonradiative recombination losses and operational instability originating from defect formation during crystallization and their subsequent evolution under illumination. Here, we show that defect formation can be regulated at the precursor stage by coordination chemistry, instead of relying only on post-crystallization passivation. A fluorinated ...

Torrefaction and hydrothermal carbonization are low-temperature thermochemical procedures for the
biomass conversion to biocoal, a carbon-neutral analog of fossil coal. Biocoals, compared to untreated biomass,
exhibit hydrophobic properties, increased energy density, and calorific value similar to that of brown coals. The
two processing methods differ essentially in that hydrothermal carbonization is performed in the presence of a
large amount ...
