N‐1 semi‐continuous transient perfusion in shake flask for ultra‐high density seeding of CHO cell cultures in benchtop bioreactors

open access: yesBiotechnology Progress, EarlyView.
Abstract One strategy to enhance the production of biological therapeutics is using transient perfusion in the preculture (N‐1 stage) to seed the production culture (N stage) at ultra‐high cell densities (>10 x 106 viable cells/mL). This very high seeding density improves cell culture performance by shortening the timeline and/or achieving higher final

Synthesis, Characterization and Application of Thioindigosulfonic Acids as Electrolytes in an Aqueous Organic Redox Flow Battery

open access: yesChemElectroChem, Volume 12, Issue 6, March 15, 2025.
The first synthesis of thioindigosulfonic acids via sulfonation of the parent dye is presented, together with the evaluation of key electrolytic properties, such as solubility and charge transfer characteristics. Investigations conducted in a flow cell demonstrated stable performance over 200 charge/discharge cycles without crossover or degradation ...

Density, viscosity, and stability of products from combinations of visbreaking and deasphalting

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Transporting bitumen through pipelines in Western Canada is cost intensive because the oil has to be diluted with light solvents to meet pipeline specifications. The diluent requirement can be reduced by visbreaking (VIS) and solvent deasphalting (SDA), each of which decrease the viscosity and density of the oil.

The effect of discontinuous injection on particle backflow in pneumatic conveying systems

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Pneumatic conveying is used in many process industries to transport dry, granular, and powdered solids. The triboelectrification of particles during conveying causes particle agglomeration, spark discharges, and disruptions in particle flow, making particles move upstream against the fluid flow. The effect of frequency of particle injection on
