A Review of Coal Fly Ash Utilization to Save the Environment

A nanoscale electrochemical guanine DNA-biosensor based on a flower-like nanocomposite of Tb-doped ZnO for the sensitive determination of pemetrexed

“…This negative potential ensured a decrease in the agglomeration of the prepared nanoparticles and better dispersion due to the electrostatic repulsion existing between each nanoparticle. 41 FL-NP Tb 3+ /ZnO as a modifier and ds-DNA had opposite surface charges, which supported their electrostatic attraction and allowed their closer contact, which was beneficial for electron transmission and ultimately the determination of pemetrexed. Hence, the optimized Tb concentration of 0.1 g was chosen to fabricate the FL-NP Tb 3+ /ZnO for further study.…”

Research on the Performance of Cement-Based Composite Borehole Sealing Material Based on Orthogonal Test

“…Fly ash is a byproduct of thermal power generation, and excessive accumulation of fly ash can have detrimental effects on the environment. By utilizing a portion of the fly ash to substitute for silicate cement, not only can the material’s performance be enhanced but also waste resources can be recycled. − The addition of a significant quantity of fly ash and PVA fibers to engineered cementitious composites (ECCs) and ultrahigh-performance fiber-reinforced cementitious composites (UHTCCs) enhances the strength and tensile strain characteristics of cementitious materials. Moreover, increasing the amount of fly ash doping results in a denser distribution of cracks in the cementitious materials, leading to improved durability. − Optimal exploitation of fly ash can enhance the mechanical qualities and durability of cementitious materials, particularly the strength during the later stages.…”

Synergistic effects of fly ash on thermal, combustion, and mechanical properties of polypropylene including intumescent flame retardant

“…While some FAs find applications in sectors such as the cement industry and road construction, a significant portion remains unused, posing a potential risk of environmental pollution 1–3 . Therefore, many studies have been conducted to explore alternative applications for FA 4–7 . One promising area is its utilization in the production of composite materials 8–14 .…”

“…[1][2][3] Therefore, many studies have been conducted to explore alternative applications for FA. [4][5][6][7] One promising area is its utilization in the production of composite materials. [8][9][10][11][12][13][14] By incorporating FA into composite material production, it becomes possible to enhance the properties of the resulting composites and simultaneously reduce production costs.…”
