Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Interplay Between Dispersion, Nucleation, and Crystallization in HDPE/Graphene Nanocomposites Processed Under Thermokinetic Conditions

Polymer Engineering &Science, EarlyView.
Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Improving Welding Behavior of ETPU Bead Foams by Surface Modification with Plasticizers

Journal of Polymer Science, EarlyView.
Tributyl citrate (TBC) and stearic acid (SA) modify ETPU beads through different diffusion mechanisms. TBC diffuses the bead structure directly after coating, whereas SA remains on the surface until melting and subsequent diffusion during heating. The resulting plasticization improves bead fusion, allowing RF processing at reduced temperature and ...

Semi‐mechanistic population PK/PD model to aid clinical understanding of myelodysplastic syndromes following treatment with Venetoclax and Azacitidine

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 448-459, March 2025.
Abstract Myelodysplastic syndromes (MDS) represent a group of bone marrow disorders involving cytopenias, hypercellular bone marrow, and dysplastic hematopoietic progenitors. MDS remains a challenge to treat due to the complex interplay between disease‐induced and treatment‐related cytopenias.

Escaping the Regional Carbon Trap: The Role of Renewable Energy Innovation in EU Decarbonisation

Sustainable Development, EarlyView.
ABSTRACT The persistence of carbon‐intensive development pathways continues to hinder progress towards climate neutrality, especially in regions where industrial legacies, infrastructural inertia, and institutional rigidities reinforce emissions.

Spectroscopic Analysis of Hydration Structures in PEG‐ and PMPC‐Containing Hydrogels by Pressure‐Controlled ATR‐IR Combined With Multivariate Curve Resolution

Surface and Interface Analysis, EarlyView.
ABSTRACT Hydration structures govern the properties and functions of hydrogels, yet selectively measuring hydration water in the presence of abundant bulk water remains analytically challenging. Here we applied pressure‐controlled attenuated total reflection infrared spectroscopy (ATR‐IR) combined with multivariate curve resolution (MCR) analysis, a ...

Microfluidic Capillary Arrays for Pixelated Control of Multimaterial Flows

Small, EarlyView.
A 3D‐printed pixellated capillary array maps up to thousands of fluid inputs into arbitrary multimaterial flow cross‐sections. Automated manifold design and laminar scaling are used to amplify printing resolution orders of magnitude, generating microscale fluidic control from printed elements, enabling designed microflows for potential use in ...

Solar‐Powered Water Depollution Through a Bioinspired Device Based on ZIF‐8 Loaded Macroporous Hydrogels Prepared via Ice‐Templating

Small, EarlyView.
ABSTRACT Water pollution poses a constant threat to the environment and is one of the central causes for global shortage of clean water. Metal–Organic Frameworks (MOFs) have emerged as highly efficient adsorbents; however, their application is limited by their common production as fine powders, which hinders recovery and reuse.
