Peroullazines: Synthesis, Structure, and Optoelectronic Properties
Chemistry – A European Journal, EarlyView.Peroullazines, longitudinally π‐extended ullazines featuring a peropyrene‐sized framework, are more electron‐rich than the corresponding peropyrene systems and exhibit optical gaps approaching those of teropyrenes. Regioselective pyridinic nitrogen incorporation further enables frontier‐orbital‐controlled tuning of their optoelectronic properties ...

Demulsifying agent simplified model for offshore oil wells
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...
