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

The 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

Polymer 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 ...

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.
