Oxide/oxide composites are being considered in the aerospace industry for the design of next-generation exhaust components. This study aims to determine the mechanical behaviour of a composite consisting in Nextel TM 610 fibres fabric (8 HSW) embedded in a porous alumina matrix. The mechanical properties were studied in tension and four-point bendi...
The Museo Egizio’s collection contains 200 precious and unique leather artifacts belonging to different historical periods. The materials used during the tanning and curing procedures affect the chemical and elemental composition of the surface of the samples as well as their preservation status, specifically through the hydration level within the ...
TaylorMade Golf Company currently uses a two-piece construction of a forged 4140 steel face and investment cast 8620 steel body for P790 golf club irons. The cast body is welded to the forged face and then the assembly is austenitized, quenched, and tempered to form tempered martensite. It is proposed that a material substitution of 8630 steel for ...
Microchannels in LC:PDMS structures must be of good quality and suitable geometry to achieve the desired orientation of the liquid crystalline molecules inside. When applying a casting technique, with the molds obtained even by the most accurate method, i.e., photolithography, it is still crucial to inspect the cross-section of the structure and th...
This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microsc...

Characterization and identification of Maitara Island clay have been carried out. This study aims to determine the types of minerals contained in the Maitara Island clay. The analytical methods used include X-Ray Fluorescence (XRF) to determine the chemical composition of Maitara Island clay, X-Ray Diffraction (XRD) for mineralogical analysis of Ma...
In Light Water Nuclear Reactors (LWRs) zinc compounds are added to the coolant water because they are known to mitigate the undesirable radioactive build up on stainless steel surfaces by displacing cobalt radioisotopes in the oxide. This work investigated the possibility of modifying the surfaces of stainless steels, which are commonly used as str...

Objectives This study evaluates the bond strength and marginal adaptation of mineral trioxide aggregate (MTA) Repair HP and Biodentine used as apical plugs; MTA was used as reference material for comparison. Materials and Methods A total of 30 single-rooted teeth with standardized, artificially created open apices were randomly divided into 3 group...
The Mozambique and Madagascar margins present major rivers that are responsible for the discharge of large amounts of terrestrial organic matter (OM) which can influence carbon cycling in marine environments. Therefore, the Mozambique channel represents a unique case to study the fate of the organic carbon in deepwater domains. Using a new and exte...
Scanning Electron Microscopes (SEMs) often generate images with a shaded appearance which gives a natural 3D impression. Ergo, quite a few methods to reconstruct the 3D surface topography from these using shape-from-shading methods are available in the literature. Here, a novel approach is discussed which uses BackScatter Electron (BSE) images from...
