Efficient Product Regulation of CO 2 Hydrogenation over an Intelligent Dual-Zeolite System

Jiaming Liang, Yitian Wang, Bowei Meng, Hengyang Liu et autres

Precisely regulating the product distribution to directly synthesize the target products with the desired compositions is of great significance for heterogeneous catalysis. However, due to the product orientation, it is difficult to achieve this purpose through a single catalytic component. Herein, we …

Preparation of halogen-free flame retardant curing agent and its application in epoxy resin

Lei Jiang, Bing Liang, Jiapeng Long

9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide-N-Aminoethylpiperazine (DOPO-AEP), a phosphorus and nitrogen intumescent flame retardant curing agent was prepared by using acetonitrile as solvent using 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and N-aminoethylpiperazine (AEP) as raw materials. The structure of the flame retardant curing agent DOPO-AEP was analyzed Fourier Transform Infrared Spectrometer …

An efficient approach for mesoscale fracture modeling of fully-graded hydraulic concrete

Lei Xu, Lei Jiang, Yefei Huang, Qingwen Ren

Large coarse aggregates used in fully-graded hydraulic concrete necessitate large specimens for numerical modeling. This leads to a high computational cost for mesoscale modeling and thus slows the development of multiscale modeling of hydraulic mass concrete structures. To overcome this obstacle, an …
