Chemistry – A European Journal, EarlyView.The first example of a simple alkylated phosphinidene‐adduct (“phospha‐Wittig”) is reported. The synthesis of Me3PPC2F5 was enabled through reaction of the cyclotetraphosphane (PC2F5)4 with PMe3. The phosphanyl‐functionalized Wittig reagent Me3PC(CF3)P(C2F5)F was prepared by treating the diphosphane P2(C2F5)4 with PMe3.

Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition
Chemie Ingenieur Technik, EarlyView.The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

A‐optimal model‐based design of experiments for processes with uncertain inputs
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

First-stage ignition delay: Application of a fast in-situ temperature sensor
, 2017 A fast temperature sensor based on intrapulse absorption has been applied to cases of two-stage ignition of iso-octane in a rapid compression machine. Two pulsed quantum cascade lasers at 5.46 and 5.60 µm respectively were used to record the spectra of ...
