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,

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

Physiology–microhabitat matching may help organisms cope with the thermal and hydric challenges under climate change: a tale of two lizards

open access: yesEcography, EarlyView.
Climate change is significantly affecting biodiversity, and organisms that depend on external temperature – such as ectotherms – are particularly vulnerable to these effects. Microhabitats provide refuge for species, thereby reducing exposure to thermal and hydric stress under climate change.

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.
