Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

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 (

Hybrid framework for on‐the‐fly diagnosis of energy inefficiency in multi‐unit processes based on data‐driven and knowledge‐based integration

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Pinpointing the true roots of energy waste in large, multi‐unit industrial systems is notoriously difficult: the data are high‐dimensional, and process units are tightly interlinked. This paper presents a powerful hybrid diagnostic framework that integrates explainable AI (XAI), Granger causality (GC), and fault tree analysis (FTA).

Pediatric Developmental Safety Assessment: Are We Ready for the Next Thalidomide?

Clinical Pharmacology &Therapeutics, EarlyView.
Pediatric drug development has achieved remarkable success in the last 20 years with over 1,000 products studied in pediatric patients. This success has been driven in part by an increased understanding of pediatric disease processes. The aspect that has been largely overlooked is the potential adverse effect of new drugs on pediatric developmental ...

Large droplet release

Droplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.
