SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =
