Fabrication of Graphene-Based Composites via High-Pressure Homogenisation and Their Characterisation
… thesis explores the potential of high-pressure homogenisation (HPH) as an efficient and versatile method for fabricating graphene and graphene-based composites. Two polymers with vastly different properties, polyamide 12 (PA12) and polyetherimide (PEI), are used to create polymer graphene …

The application of the homogenisation method to the numerical modelling of cancellous bone
… microstructural mechanical behaviour using the homogenisation method. In total joint replacement, cancellous bone (the soft porous bone which lies below the articular surfaces at weight-bearing joints) provides the medium for the transfer of loads from the artificial component, or prosthesis to …

Durch Hochdruck-Homogenisation gewonnene Mistelpräparate : Charakterisierung der Membranvesikel und deren Wechselwirkung mit aktiven Inhaltsstoffen
… im Mistelextrakt untersucht. <br>Bei der Homogenisation von Pflanzenmaterial in wässrigem Medium nach dem Press-Spalt-Prinzip unter Gasausschluss wird das Zellgewebe intensiv aufgeschlossen und sehr effektiv in die Dispersion überführt. Membranen der Zellen und der Organellen werden durch …

Homogenisation of titanium - 6 aluminium - 4 vanadium (TI-6AL-4V) powder blends during sintering
Titanium alloys have received significant attention in recent years primarily within the aerospace sector due to their superior material properties, high strength to weight ratios and high resistance to corrosion. However, high processing costs associated with the alloys have hindered their usage …

Correlation between homogenisation parameters and property evolution of AA3104 CBS after hot finish rolling
… stages, including direct chill (DC) casting, homogenisation, hot rough rolling, hot finish rolling, and cold rolling. Homogenisation is an important phase that controls the growth of intermetallic particles (IMPs) and dispersoids, affecting mechanical performance and texture evolution in …

The study of intermetallic particles in aluminium alloy AA3104 can-body stock during homogenisation
… earing, tear-off and galling resistance. During homogenisation of AA3104 direct chill (DC) ingot, there is a phase transformation from β-Al₆(Fe,Mn) orthorhombic phase to the harder α-Alₓ(Fe,Mn)₃Si₂ cubic phase. Phase transformation occurs by diffusion of Si and Mn, where diffusion of Mn …

Relationships between homogeneity, structure and mechanical properties in certain sintered iron, nickel, carbon materials.
… the quantitative measurement of the degree of homogenisation that had occurred in each of these materials during sintering. The homogenisation parameter so determined was related to the mechanical and physical properties and microstructure of the materials after these had undergone various …

High temperature fracture behaviour of laser-powder bed fusion produced nickel superalloy
… The first heat treatment uses a high temperature homogenisation at 1110 °C for 2 hours followed by water quenching, while the second used a lower homogenisation at 1020 °C for 1 hour followed by water quenching. Both heat treatments were subsequently aged at 720 °C for 24 hours. Specimen quality …

Investigating the potential use of sparse-input reanalyses to homogenise long-term land surface air temperature records
… of meteorological observational records (homogenisation) for non climate artefacts is an important task. Very few, long-term meteorological station series are entirely free of non-climatic influences. Climate data homogenization aims to identify and remove these non climate factors. …

The formulation, testing and stability of 16% fat cream liqueurs
… one-step process, where alcohol was added before homogenisation, were more stable than those processed by a two -step process which involved addition of alcohol after homogenisation. Using the one-step process, it was possible to produce creaming-stable liqueurs by using one pass through a …

Composition and microstructure evolution in semi-solid cast Al-Zn alloys
… placing high demands on the post-solidification homogenisation and solution heat treatments, in order to derive optimum strength during subsequent ageing treatments. If the semi-solid metal castings can be age hardened to the same extent as the equivalent wrought competition, then this process …

Factors affecting the quality of low-fat cheeses
… of levels of titanium dioxide, annatto and homogenisation pressure on the properties of reduced-fat Cheddar cheese were evaluated. Titanium dioxide led to cheeses with reduced translucency and an opposite trend was observed in cheeses made with annatto. Homogenisation of cheesemilk led to an …

The modelling of natural fibre-reinforced composites using a multi-scale methodology
… elasticity is presented in this thesis. The homogenisation process is discussed in general, with particular attention to the required boundary constraints on the micro-domain and the extraction of an effective elastic modulus. For the case of a non-linear problem the enforcement of the …

The effects of heuweltjies and Microhodotermes viator (Isoptera: Hodotermitidae) on invertebrate assemblages and species turnover in the succulent Karoo, Western Cape
… Jaccard distances indicated that environmental homogenisation of the heuweltjies resulted in homogenisation of the on-mound invertebrate communities. Heuweltjie soil enrichment was most similar to that of termite frass when compared to the matrix, supporting a termite origin for the heuweltjies.

Modelling-based design of anisotropic piezocomposite transducers and multi-domain analysis of smart structures
… Design of piezocomposites requires accurate homogenisation models for the prediction of the equivalent electro-mechanical properties. In macro-scale models of structures with piezocomposite transducers, these properties are adopted in order to avoid the complexity of the piezocomposite …

Developing Constitutive Laws for the Endothelial Glycocalyx Layer
… Next, in the second part of this work, we use homogenisation theory to derive a more sophisticated model for the EGL. Using homogenisation, we are able to obtain bulk EGL properties such as the permeability from the underlying microstructure of the EGL. In addition, we are also able to evaluate …
