Boundaries: Interfacial Flux in Environmental Flows’” W thank Thibodeaux et al. for their interest in our recent article in Environmental Science & Technology. While they touch on numerous topics, their chief criticism of our article can be summarized as follows: hyporheic exchange is an advective process, and therefore cannot be represented by a mass transfer coefficient (or its inverse, the m...

A porous Ni-Fe oxide with improved crystallinity has been prepared as a highly efficient electrocatalytic water oxidation catalyst. It has a small overpotential, a low Tafel slope, and an outstanding stability. The remarkably improved electrocatalytic performance is due to the porous structure, high extent homogeneous iron incorporation, ameliorative crystallinity, and the low mass transfer res...

This work deals with modeling and simulation of SO2 removal in a ceramic membrane by means of FEM. A mass transfer model was developed to predict the performance of SO2 absorption in a chemical solvent. The model was based on solving conservation equations for gas component in the membrane. Computational fluid dynamics (CFD) of mass and momentum were used to solve the model equations. The simul...
