Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Decoupling Formulation and Processing Effects in Thermoplastic Starch Through a Data‐Driven Structure–Property Framework

open access: yesPolymer Engineering &Science, EarlyView.
Processing‐property relationships in thermoplastic starch (TPS): plasticizer type, starch source and melt‐processing temperature establish a hierarchy of effects that governs process‐induced changes and the resulting TPS properties. ABSTRACT Thermoplastic starch (TPS) is a melt‐processable biopolymer whose properties depend strongly on formulation and ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

CD68 and F4/80 Markers Demonstrate Inflammatory Synergism Between Apical Periodontitis and Liver Fibrosis in Wistar Rats

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To evaluate CD68 and F4/80 glycoproteins in the worsening of apical periodontitis (AP) and liver fibrosis (LF) in Wistar rats. Methodology Thirty‐two Wistar rats were distributed in the following groups (n = 8): C—control; AP—apical periodontitis; LF—liver fibrosis; APLF—AP and LF.
