This issue marks the start of our Pathways to Net-Zero GHG Emissions Special Series, with this month’s editor’s choice as the inaugural article: “Reduction of greenhouse gas emissions via flexible operation of cross-sector integrated energy systems under uncertainties in demand, fuel prices, and solar irradiation.” In it, Ruonan Li and Vladimir Mahalec explore how flexible production can lead to reductions in the greenhouse gas emissions of integrated energy systems, as well as provide significant cost savings.

Also highlighted in this issue is Rodolfo de Andrade Schaffner et al.’s article, “Green synthesis of templated porous carbons,” in which the researchers synthesized mesoporous carbons using a method that is simple, inexpensive, and reproducible “using readily available raw materials of low toxicity and hazard.” Good news, considering that “porous carbon materials such as activated carbons are widely used industrially for the purposes of purification, decolourization, deodorization, and gas storage, among others.”

The third highlight of July is the “Effect of the fibre diameter polydispersity on the permeability of nonwoven filter media” written by Dominique Thomas, Nathalie Bardin-Monnier and Augustin Charvet in which they use 3-D simulations to study “the permeability values of air filter media” and propose two expressions “to calculate the equivalent fibre diameter to use in the permeability correlation.”

The final issue highlight, “A continuous flow reactor for the flexible production of different formulations: CFD-aided design” by Riccardo Bacci di Capaci et al., develops a solution for the “flexible production of several fine chemicals” in what is “basically an inline reactor equipped with different static mixers and inlets conceived to ensure on-site production.” The implementation of such innovative designs that are able to produce “a set of specific formulations for the chemical and health sectors” could help to meet the chemical demands of future pandemics.

As a hybrid journal, CJCE is always looking for open access submissions to the journal so that more of our articles are always free to read, download, and share for everyone. To find out if you are eligible to have your article publication charges for open access covered, visit Wiley’s author services for more information. In Canada, the 75+ member institutions of the Canadian Research Knowledge Network (CRKN) cover article publication charges through their transformational agreement with Wiley. And with a new, easier to use submissions interface, there’s more reason than ever to submit your article to CJCE today.
