Currently, triazole-containing compounds, including polymers, are of great interest to the global scientific community. This article is devoted to computational and theoretical studies of highly filled propellant compounds using triazole polymers as a fuel binder. Using a computational method with the REAL software package, the dependences of certain parameters of theoretical propellant compositions (combustion temperature, powder force, amount of gaseous combustion products) on the degree of filling of the polymer binder with powerful high explosives (HEs), such as hexogen—RDX, hexanitrohexaazaisowurtzitane—CL-20, and tetranitropentaerythritol—PETN, have been determined. The calculated data show the prospects of using triazole polymers as a basis for creating high-energy propellant compounds capable of competing with the well-known nitrocellulose filled matrices. The use of triazole polymers considered in this work, according to calculations, makes it possible to increase the level of gunpowder strength of filled (by 80
In the current study, the conditions for multiple processing of lithium-ion batteries were investigated. The best separation of cathode and anode material from the other internal components of the LIBs could be achieved by intensive water scraping, which resulted in an overall electrode material recovery of 92–96
The effect of iron filler extracted from industrial waste to improve thermo-mechanical properties of epoxy matrix composites to offer sustainable energy storage was studied. In particular, α-iron filler (BCC) particles with average size of 50 µm, obtained by ball milling, were used in different tenors (5, 10 and 15 wt
A simplified air-restricted closed-crucible treatment of sawdust-based feedstock was compared with nitrogen-flow torrefaction at 300°C for 0.5–4 h to assess the effect of forced volatile removal on biochar fuel properties. Thermogravimetric analysis showed that 300°C lies within the active decomposition interval of the feedstock. At 300°C and 1 h, nitrogen-flow torrefaction gave deeper deoxygenation, approximately 55
An efficient and environmentally friendly method was developed for the synthesis of novel 1,8-naphthyridine derivatives through a one-pot multicomponent reaction under ultrasonic irradiation. The reaction of quinoline-2-amine, malononitrile, and various substituted aldehydes was carried out in water using morpholine as a catalyst, affording the desired 1,8-naphthyridine-3-carbonitrile derivatives in high yields within a short reaction time. The ultrasound-assisted protocol significantly improved reaction efficiency compared with conventional methods by reducing reaction time and increasing product yield under mild conditions. The synthesized compounds were characterized by FT-IR, 1H NMR, 13C NMR, and mass spectrometry, confirming their molecular structures. The antioxidant potential of the synthesized derivatives was evaluated using the DPPH free radical scavenging assay. Among the series, compounds 4g and 4j exhibited the most promising antioxidant activity with lower IC50 values, indicating strong radical-scavenging ability. Furthermore, in-silico ADME and drug-likeness analyses using the SwissADME platform revealed that most compounds possess favorable physicochemical properties, good gastrointestinal absorption, and compliance with drug-likeness rules. Overall, this study presents a rapid and green synthetic strategy for generating biologically relevant 1,8-naphthyridine derivatives with promising antioxidant properties. The developed methodology supports Sustainable Development Goals (SDG 3: Good Health and Well-being and SDG 12: Responsible Consumption and Production) by promoting environmentally responsible chemical synthesis and potential therapeutic discovery.
