Dynamics of CD44+ bovine nucleus pulposus cells with inflammation
Scientific ReportsIntervertebral Disc (IVD) degeneration has been associated with a chronic inflammatory response, but knowledge on the contribution of distinct IVD cells, namely CD44, to the progression of IVD degeneration remains elusive.

Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis
The Canadian Journal of Chemical Engineering, EarlyView.The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for

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 ...

The Canadian Journal of Chemical Engineering, EarlyView.Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.

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 =
