Nonsimilar analysis of ternary hybrid Eyring–Powell nanofluid flow over a linearly stretching surface

“…To validate the accuracy and the efficiency of the numerical procedure used here through the LNS method via bvp4c, computations for the values of the Nusselt number in terms of − θ′(0) are carried out for variation in Prandtl Number (Pr⁡). The resulting data are compared with the available published results of Cortell (2007) who utilized the Runge–Kutta algorithm for the Nusselt number, Rana and Bhargava (Akakuru et al ., 2020) used the explicit finite element method to solve the differential equations, and Reddy (Sparrow and Yu, 1971) used the Runge–Kutta scheme to solve the Eyring–Powell model. From our observation of the tabular data which appears in Table 3, favorable agreement has been obtained with our results.…”

“…These include their cost-effectiveness in manufacturing, remarkable mechanical and chemical stability, transparency when used in thin films, bio- and chemical inertness, hydrophilicity, exceptional efficiency in converting light and corrosion resistance. TiO₂ nanoparticles find applications across a wide spectrum of products and fields, encompassing areas such as nanomedicine, nanobiotechnology, solar panels and electrochemical batteries, production of food, soil rehabilitation, gas detection technology, polymers, paint and parchment industries, hydrogen fuel generation, as well as inks used for printing (Shi et al ., 2013; Akakuru et al ., 2020). In addition, the dynamic features of HNF flow in a porous medium are not being investigated using the LNS technique (Sparrow and Yu, 1971; Razzaq and Farooq, 2021; Hussain et al ., 2023).…”

Visible-Light-Assisted Photocatalytic CO2 Reduction and N2-Fixation over TiO2/Covalent Organic Framework Heterojunction Photocatalyst

“…In this regard, it is well established that TiO 2 has gained extensive attention owing to its promising applications in solar and electrochemical cells, photocatalysis, cosmetics, nanomedicine, lithium-ion batteries, wastewater treatment, gas sensing, production of hydrogen fuel, self-cleaning devices, and printing inks. – Though, due to some inherent limitations like wide optical band gap energy, high recombination rate of photoinduced charge carriers, and photoactivity of TiO 2 has been restricted to satisfy the necessities of visible light-irradiated catalytic reactions. – In this regard to improve the photocatalytic activity, several types of heterostructures are becoming a topic of interest among the efficient approaches to researchers all over the world day-by-day. – However, additionally being expensive and lacking high-quality metals, these inorganic–inorganic hybrid materials have obvious disadvantages, such as a lower surface area, low light absorption power, and slow transmission of photogenerated carriers. In recent times, Li et al prepared FeN-CDs/TiO 2 @CN, a multiheterojunction-structured material which showed outstanding photocatalytic N 2 fixation activity .…”

A Review of the Removal of Dyestuffs from Effluents onto Biochar

“…Dyestuffs color and pollute receiving waters, streams, and rivers as a result of inadequate processing of the industrial effluents by a variety of industrial applications including the food and beverage companies, paper and pulp processing, paint manufacturing, pharmaceutical processing, printing, textiles, dyeing, and printing [1]. Many dyes pose a grave danger to the water environmental ecosystem due to their chemical properties, with serious consequences for human health, animal, and plant ecosystems [2,3].…”
