Unraveling the role of agro waste-derived graphene quantum dots on dielectric and mechanical property of the fly ash based polymer nanocomposite

Activity features of catalysts for thermocatalytic hydrogenation processing of polymer waste

“…The main conclusions obtained as a result of the physicochemical studies and experimental tests of catalysts in this work are in agreement with the data mentioned in the scientific literature [2,5,[32][33][34][35][36][37][38][39][40][41].…”

“…The problem of environmental pollution with carboncontaining industrial and household waste based on polymer and rubber products needs to be addressed. The main ways of the disposal of such waste are incineration and storage [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. If we consider these carbon-containing wastes as an alternative source of hydrocarbons, then the development of new integrated technologies based on the use of effective catalysts will allow us to fully solve the existing environmental threats in the future.…”

Sustainable robust waste-recycled ocean water-resistant fly ash-carbon nanotube nanocomposite-based triboelectric nanogenerator

“…In addition, currently in the world, electricity generation comprises about 70% of coal-based thermal power stations, which are likely to remain important in near the future. However, during the power generation process, a very high amount of fly ash of about 250 MT is generated every year, 29 which contains mainly SiO 2 , FeO, Al 2 O 3 , NaO and other heavy and toxic elements that create severe health issues. To date, fly ash is not properly utilized and a large quantity is dumped in open spaces, thus creating pollution.…”

Paddy-Straw-Derived Graphene Quantum Dots Reinforced Vertical Aligned Zinc Oxide Nanosheet-Based Flexible Triboelectric Nanogenerator for Self-Powered UV Sensors and Tribotronics Application

“…In addition, agro residues have also been used to generate biogas and biofuel such as ethanol; however, under this procedure, paddy straw still undergoes the burning process and produces secondary waste, and a very minor quantity of the paddy straw is utilized. , Therefore, searching a novel way to utilize paddy straw in advanced applications is desired. The paddy straw was used to prepare the graphene quantum dots from a simple and novel hydrothermal method. , Graphene quantum dots (GQDs), a single atomic layer of carbon, exhibit advanced and unique properties from those of their bulk counterparts, endowing them with remarkable advantages in various potential applications, such as for fabrication in flexible display fabrication, biosensors, energy/photovoltaic devices, field-effect devices, and drug delivery applications. − However, the use of paddy-straw-derived GQDs with 2D ZnO nanosheets for TENG application and self-powered UV sensors for tribotrincs application is not yet reported. Our present work will also provide a circular economical approach and advanced sustainable solution associated with the global problem of paddy straw burning in farmers’ fields via a facile, low cost, and environmentally friendly route for the development of high performance flexible GQDs and vertically aligned ZnO nanosheet-based devices for energy, sensors, and tribotronics applications for the first time.…”
