Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$

Tailoring phosphate mining waste into high‐performance geopolymers: A sustainable process for selective CO2/N2 separation

The Canadian Journal of Chemical Engineering, EarlyView.
Overview of the synthesis, structural features, and CO2 capture performance of geopolymer‐based adsorbents prepared from phosphate mining waste, including granular and spherical materials with high surface area, CO2 capture capacity, and CO2/N2 selectivity.

Thermodynamic sensitivity and transferability limitations of Pharma Mod UNIFAC for aqueous solubility prediction of sulfonamide APIs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Predicting the aqueous solubility of active pharmaceutical ingredients (APIs) remains challenging because highly dilute systems are particularly sensitive to activity‐coefficient calculations and solid‐reference thermodynamic properties. In this work, we evaluated Pharma Mod UNIFAC for predicting the aqueous solubility of sulfonamide‐based ...

Vine copula knockoffs for variable selection in gene expression studies

Canadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.
