Engineering Reports, Volume 5, Issue 1, January 2023., 2023 This article deals with modeling and numerical study of pollutants transfer in porous media by topological optimization. Indeed we perform the modeling of pollution in porous media in non‐permanent cases by assuming the variability or not of some parameters such as the conductivity and the density.

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Since cholesterol triggers many diseases, many methods have been developed for its determination. In this study, an alternative system for cholesterol determination was developed by preparing amperometric biosensors. In the development of the biosensor, Pt/polypyrrole–polystyrene sulfonate film was prepared by electropolymerization of ...
