Pre‐Existing and New‐Onset Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Implantation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Atrial fibrillation (AF) is a frequent comorbidity in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). In addition, new‐onset AF can occur after TAVI. However, data on how AF affects outcomes in patients undergoing TAVI remain conflicting.

Ucuúba Fat (Virola surinamensis) and Cellulose Nanocrystals Functionalizing Cassava (Manihot esculenta)  Starch Films

open access: yesChemFoodChem, EarlyView.
Cassava starch films were functionalized with Ucuúba fat and cellulose nanocrystals to tailor wettability, optical, mechanical, and barrier properties. Integrating Amazonian bioresources with nanotechnology enables sustainable edible coatings with tunable performance for fresh food preservation and enhanced UV protection.

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

open access: yesThe 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 ...

Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

open access: yesThe 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

open access: yesThe 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 =
