Modelling and simulation of hydrogen production via natural gas plasma pyrolysis

The Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1174-1189, March 2026.
Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.

IN-SOURCE AND POSTIRRADIATION POLYMERIZATION OF ACENAPHTHYLENE IN THE SOLID-STATE

, 1992
Radiation-induced solid state polymerization of acenaphthylene was studied by using Co-60-gamma-rays. The extent of polymerization at room temperature reached 68% when acenaphthylene was irradiated with a dose of 2.5 MGy.

π‐Expanded Fluoranthenes as Chromophores With Tailored Properties

Helvetica Chimica Acta, Volume 109, Issue 3, March 2026.
A series of π‐expanded fluoranthene scaffolds selectively functionalized with electron donors and acceptors were synthesized. The evolution of the structural, optoelectronic, and redox properties in relation to substitution and cyclization was comprehensively studied both in experiment and in theory. The results identify the compounds as highly tunable
