Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.
