This study investigates the influence of initial pH on anodic biofilm formation of microbial electrolysis cells. Initial pH affects the activities of microorganisms in MEC, and furthermore will affect hydrogen (H₂) generation. Therefore, we explore the effects of initial pH on anodic biofilm formation of microbial electrolysis cells and the intrinsic reasons. In a single-chamber MEC, with different...
Classifying loess deposits is an important process for selecting support form and construction methods for tunnels. An accurate evaluation of loess deposits is a necessary prerequisite to control deformation, save cost, and improve construction efficiency. In this paper, a neural network model with an evaluation system consisting of physical and mechanical indices of loess is proposed to realize intelligent...
This study aims to investigate the enzymatic hydrolysis of waste-activated sludge (WAS) using free and immobilized alkaline protease. Alkaline protease was immobilized on graphene oxide (GO) sheets using glutaraldehyde as cross-linking reagent. The storage stabilities, kinetic parameters, physical properties, and the free amino acid (FAA) profiles of the WAS protein hydrolysates from free and immobilized...
