Dear Colleagues,

Due to low thermal conductivity, conventional fluids like water, ethylene glycol, and oil have a restricted cooling performance. This restricted cooling performance can be determined by the addition of a small amount of nanosolid particles with high heat transfer performance to the traditional fluid to form so-called nanofluids. Typically, particles in such nanofluids have dimensions ranging from 1 to 100 nm and take the form of metals, oxides, carbides, nitrides, or nonmetals. There are several engineering and physical applications of heat transfer in nanofluid are such as engine cooling, refrigerators, chillers, microelectronics, fuel cells, etc.

The recent research shows that nanofluids synthesized by chemical solution methods have both higher conductivity enhancement and better stability than those produced by the other methods. With the development of nanofluids, there is increasing interest in using nanofluids in environmental sectors, especially in chemical treatment. Nanofluids are not strong oxidants and are not expected to produce harmful disinfection byproducts. Nanofluids exhibit good disinfection properties against a wide range of bacteria, including Gram-negative, Gram-positive, and spore-forming bacteria. Several patents disclose the typically used types of nanofluids and their possible disinfection/decontamination mechanisms. 

Recently, mathematical modeling of nanofluids, representing a novel class of chemical processes that play a vital role in industries and environment, has been widely considered by researchers with attractive and useful applications. Usually, these models are represented in terms of traditional integer-order partial differential equations (PDEs). Note that the traditional PDEs cannot decode the complex behavior of physical chemical processes and memory effects. To address these defects, researchers have focused on fractional dynamic systems of fractional nonfluids in water-cleaning processes.

Topics:

• Fractional nanofluids in chemical processes with singular/nonsingular kernels
• Water process in hybrid nanofluids with (singular/nonsingular and local/nonlocal) kernels
• Innovative fractional applications in nanotechnology, wastewater, filtration, photocatalysis, sensor, and antimicrobial nanomaterials
• Wastewater treatment, nanoengineered material, membrane technology, nanosorbents, adsorption, and metal oxides with new fractional derivatives
• Application of reverse osmosis, water softening, water treatment, membranes, and fouling in fractional hybrid nanofluids
• Numerical and analytical solutions in chemical processes of fractional problems for different geometries
• Mathematical models of fractional hybrid nanofluids in materials and bioscience
• Role of fractional hybrid nanofluids in adsorption, activated carbon, wastewater, and central composite design
