On the Influence of Catalyst Mesopore Structure in the Catalytic Cracking of Polypropylene

open access: yesChemistryEurope, EarlyView.
Catalytic cracking is a promising approach to convert polyolefin plastics into hydrocarbons. Herein, the effect of catalyst pore size in polypropylene cracking using amorphous silica–alumina with identical external acidity, but varying mesopore diameters and particle sizes, is isolated. Mesopore size has minimal effect on activity, indicating that high

Dynamic accelerated solvent extraction for faster oil sands oil, water, and solids determination and solids cleaning

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
25 g of oil sands extracted by dynamic accelerated solvent extraction, yielding 177 mL of bitumen–toluene extract and clean dried solids in approximately 12 min. Abstract Determining the oil, water, and solids (OWS) contents of oil sand is essential to many aspects of the oil sands industry including mine planning, optimization of extraction processes,

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

open access: yesCytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
