Numerical modelling of the aluminium extrusion process and comparison with results obtained from industrially extruded complex sections.

open access: yes
This thesis reports the analysis of extruded products by Forge2009® and EBSD produced by the investigator in the BOAL plant. The 3D FEM module was used to study the required load, the temperature evolution, surface formation of the extrudate and material

Investigation of thermal and viscoelastic properties of polymers relevant to hot melt extrusion - I: Polyvinylpyrrolidone and related polymers [PDF]

open access: yes, 2016
Polymers are essential components of melt extruded products. The objective of the present study was to generate physicochemical data of polyvinylpyrrolidone-based polymers and copolymers that are used in hot melt extrusion (HME).

Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood

open access: yesAdvanced Science, EarlyView.
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

Hot Melt Extrusion Technology in Taste Masking

open access: yesAAPS PharmSciTech
Abstract Hot melt extrusion (HME) is a widely used method of taste masking in medication formulations, notably for bitter Active Pharmaceutical Ingredients (APIs). This continuous, solvent-free technique successfully wraps APIs within a polymer matrix, forming a barrier that considerably decreases bitterness perception.

Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

open access: yesAdvanced Science, EarlyView.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

Analysis of the conform process: a specific form of aluminium extrusion.

open access: yes
Since the Conform process was patented 30 years ago, there have only been approximately 200 machines sold worldwide. Given that Conform competes economically with conventional extrusion and is also reported to be a more energy efficient process, it is ...
