Numerical investigation on 2D viscoelastic fluid due to exponentially stretching surface with magnetic effects: an application of non-Fourier flux theory

Two-dimensional flow of Casson fluid toward an exponentially stretched surface in view of Cattaneo–Christove flux theory is discoursed in current communication. Flow pattern within boundary layer under the effectiveness of magnetic field is also contemplated in the communication. Non-dimensionalized governing expressions are attained through transformation procedure. To anticipate the fascinating features of present work, solution of resulted nonlinear differential system is computed with the collaborated help of shooting scheme and Runge–Kutta method. The influence of involved variables on velocity and temperature fields is scrutinized. Contribution of thermal relaxation is explicitly pointed out. Evaluation of convective heat transfer and friction factor in the fluid flow is visualized through graphs and tables. Additionally, the assurance of present work is affirmed by developing comparison with previous findings in the literature which sets a trade mark for the implementation of numerical approach. It is inferred from the thorough examination of the analysis that present formulation reduces to classical Fourier’s problem by considering \(\varLambda = 0\). Furthermore, decreasing pattern in temperature distribution is depicted in the presence of Cattaneo–Christove flux law as compared to heat transfer due to the Fourier’s law.

     

Potential applications of peroxidases

Peroxidases are oxidoreductases produced by a number of microorganisms and plants. Peroxidases catalyse a variety of reactions in the presence of peroxides such as hydrogen peroxide. Oxidative polymerisation of phenols and aromatic amines, conducted by horseradish peroxidase (HRP) in water and water-miscible organic solvents, may lead to new types of aromatic polymers. Peroxidase has a potential for soil detoxification, while HRP, as well as soybean and turnip peroxidases have been applied to the bioremediation of waste waters contaminated with phenols, cresols and chlorinated phenols. Lignin peroxidase (LiP) and manganese peroxidase (MnP) may be successfully used for biopulping and biobleaching in the paper industry and can produce oxidative breakdown of synthetic azo dyes. Peroxidase-based biosensors have found use in analytical systems for determination of hydrogen peroxide and organic hydroperoxide, while, co-immobilized with hydrogen peroxide-producing enzyme, they can be used for determination of glucose, alcohols, glutamate and choline. Peroxidase has also been used for practical analytical applications in diagnostic kits, such as quantification of uric acid, glucose, cholesterol, lactose, etc. Enzyme-linked immunosorbent assay (ELISA) tests, in which peroxidase enzyme is the most common enzyme used for labelling an antibody, are a simple and reliable way of detecting toxins, pathogens, cancer risk in bladder and prostate, and many other analytes.
