Abstract X-ray computed tomography (CT) is frequently used for non-destructive testing with many applications in a wide range of scientific research areas. The difference imaging speeds between synchrotron and lab-based scanning has reduced as the capabilities commercially available CT systems have improved, but there still need faster both industry academia. In high-speed desirable inline high-throughput at higher resolution than currently possible which would save time money. academia it...
Abstract This case report presents one of the first reported uses a 3D printed exhibit in an English homicide trial, which two defendants were accused beating their victim to death. The investigation this crime included micro‐ CT scan victim's skull, assisted pathologist determine circumstances assault, particular regarding number assault weapons and perpetrators. showed distinct injury shapes, suggesting use either or single weapon with geometrically surfaces. It subsequently served as...
Hierarchical ZSM-5 coatings supported on macrocellular β-SiC foams were prepared by a microwave-accelerated secondary growth method. Under microwave irradiation, differential heating was enabled due to the high microwave-adsorbing ability of SiC leading fast assembly zeolites foams. The effects crystallisation temperature, time and agitation also investigated under heating. A specific surface area ca. 52 m2 g−1 obtained optimum condition 150 °C 4 h. Comparative studies conventional...
Abstract The multisensory aspect of the museum, while neglected for many years, is undergoing a resurgence as museum workers have begun to push towards re‐establishing senses major component pedagogy. However, museums roadblock lies in need conserve rare objects, that prevents visitors from being able interact with objects meaningful way. This issue can be potentially overcome by rapidly evolving field 3D printing, which allows handle authentic replicas without damaging originals. little...
Compression moulding of carbon fibre sheet compounds is an attractive manufacturing method for composite structures. Investigating orientation, defects and voids in these components important quality control. X-ray computed tomography a non-destructive imaging used on different kind moulded compound to identify such issues, but it still challenge due the similarities density fibres polymer matrix. This study aims determine best-practice optimising acquisition parameters composites. The first...
This case study reports the novel application of three-dimensional technologies such as micro-CT and 3D printing to forensic investigation a complex dismemberment. Micro-CT was successfully employed virtually align severed skeletal elements found in different locations, analyse tool marks created during dismemberment process, dissect charred piece evidence. High resolution prints burnt human bone contained within were for physical visualisation assist team. radiological method provided vital...
X-ray computed tomography (CT) offers significant potential as a metrological tool, given the wealth of internal and external data that can be captured, much which is inaccessible to conventional optical tactile coordinate measurement machines (CMM). Typical lab-based CT take upwards 30 min produce 3D model an object, making it unsuitable for volume production inspection applications. Recently new generation real time (RTT) x-ray has been developed airport baggage inspections, utilising...
Forensic imaging technology has rapidly advanced over the past several decades and is gaining increasing significance in medico-legal death investigations. Medical-grade computed tomography (CT) now routinely used post-mortem examinations at numerous institutions across globe. However, resolution of medical-grade CT limited unsuitable when to depict some smaller anatomical structures or micro-trauma. High-resolution micro-CT offers up 100× overcome this problem but a very recent addition...
Engineered subsurface barriers with reduced porosity and permeability are critical for safe storage of CO2 H2, the prevention pollutant transport, several other flow challenges. This study investigates enzyme-induced carbonate precipitation (EICP), a promising technique potential to achieve uniform in otherwise inaccessible regions, provided mechanisms pore-scale mixing well understood. High-speed lab x-ray computed tomography modelling were used reagent precipitation. Our experiments show...
Sn based anodes for sodium-ion batteries are examined in relation to the morphological changes driven by formation of a porous “coral-like” structure. We explore conditions that promote its and evaluate impact on cycling stability.
Additive manufacturing (AM) is uniquely suitable for healthcare applications due to its design flexibility and cost effectiveness creating complex geometries. Successful arthroplasty requires integration of the prosthetic implant with bone replace damaged joint. Bone-mimetic biomaterials are utilised their mechanical properties porous structure that allows ingrowth fixation. The predictability predetermined interconnected structures produced by AM ensures required shape, size tissue...
X-rays generated by betatron oscillations of electrons in a laser-driven plasma accelerator were characterised and applied to imaging industrial samples. With 125 TW laser, low divergence beam with 5.2±1.7 × 107 photons mrad−2 per pulse was produced synchrotron spectrum critical energy 14.6±1.3 keV. Radiographs obtained metrology test sample, battery electrodes, damage site composite material. These results demonstrate the suitability source for non-destructive evaluation applications. The...
X-ray Computed Tomography (XCT) has become a common tool for dimensional analysis as it allows non-destructive internal and external measurements. Manufacturers often specify the accuracy of dedicated metrology XCT systems maximum permissible error (MPE) statement determined using workpieces, test lengths positions that are significantly different between manufacturers. The VDI/VDE 2630-1.3:2011 guideline provides specification respective methods to verify performance against these MPE...
Abstract Small Fe-based droplets have been heated to a molten phase suspended within slag medium replicate partial environment the basic oxygen furnace (BOF). The confocal scanning laser microscope (CSLM) has used as heating platform interrogate effect of impurities and their transfer across metal/slag interface, on emulsification droplet into medium. samples were then examined through X-ray computer tomography (XCT) giving mapping emulsion dispersion in 3D space, calculating changing...
BACKGROUND: In computed tomography (CT), the spot geometry is one of main sources error in CT images.Since X-rays do not arise from a point source, artefacts are produced.In particular there penumbra effect, leading to poorly defined edges within reconstructed volume.Penumbra models can be simulated given fixed and known experimental setup.OBJECTIVE: This paper proposes use model, derived Beer's law, both confirm data, quantify blurring image.METHODS: Two for considered; consists single...
