3D computational anatomy of the scaphoid and its waist for use in fracture treatment

3D computational anatomy of the scaphoid and its waist for use in fracture treatment

A detailed understanding of scaphoid anatomy helps anatomic fracture reduction and optimal screw position. Therefore, we analyzed the size and shape variations of the cartilage and osseous surface, the distribution of volumetric bone mineral density (vBMD), and if the vBMD values differ between a peripheral and a central screw pathway?

Forty-three fresh frozen hand specimens (17 females, 26 males) were analysed with high-resolution peripheral quantitative computed tomography (HR-pQCT) ... Read more

Scientists use Avizo to capture the complex dynamics of particle movement in granular materials

Scientists use Avizo to capture the complex dynamics of particle movement in granular materials

Scientists have for the first time captured the complex dynamics of particle movement in granular materials, helping to explain why mixed nuts often see the larger Brazil nuts gather at the top. This phenomenon, known as the ‘Brazil-nut effect’, has huge implications for industries where uneven mixing can critically degrade product quality. The findings could have vital impact on industries struggling with the phenomenon, such as pharmaceuticals and mining.

Pore-scale mechanisms of CO2 storage in oilfields

Pore-scale mechanisms of CO2 storage in oilfields

Rapid implementation of global scale carbon capture and storage is required to limit temperature rises to 1.5 °C this century. Depleted oilfields provide an immediate option for storage, since injection infrastructure is in place and there is an economic benefit from enhanced oil recovery. To design secure storage, we need to understand how the fluids are configured in the microscopic pore spaces of the reservoir rock. We use high-resolution X-ray imaging to study the flow of oil, water and ... Read more

Hot-wire arc additive manufacturing of aluminum alloy with reduced porosity and high deposition rate

Hot-wire arc additive manufacturing of aluminum alloy with reduced porosity and high deposition rate

Wire arc additive manufacturing (WAAM) technology has attracted considerable interest in large-scale metallic components, but porosity and low deposition rate are the two dominating technical challenges in WAAM of aluminum alloy. In order to effectively solve these problems, a novel method of hot-wire arc additive manufacturing is used to fabricate aluminum alloy. Systematic studies are carried out to investigate the formation mechanism of the pores, the macro/microstructures, as well as the ... Read more

Investigating the microstructure and mechanical behaviour of simulant “lava-like” fuel containing materials from the Chernobyl reactor unit 4 meltdown

Investigating the microstructure and mechanical behaviour of simulant “lava-like” fuel containing materials from the Chernobyl reactor unit 4 meltdown

Decommissioning of the damaged Chernobyl nuclear reactor Unit 4 is a top priority for the global community. Before such operations begin, it is crucial to understand the behaviour of the hazardous materials formed during the accident. Since those materials formed under extreme and mostly unquantified conditions, modelling alone is insufficient to accurately predict their physical, chemical and, predominantly, mechanical behaviour. Meanwhile, knowledge of the mechanical characteristics of thos... Read more

Accurate detection, characterization, and prediction of defects has great potential for immediate impact in the production of fully-dense and defect free metal additive manufacturing (AM) builds. Accordingly, this paper presents Defect Structure Process Maps (DSPMs) as a means of quantifying the role of porosity as an exemplary defect structure in powder bed printed materials. Synchrotron-based micro-computed tomography (μSXCT) was used to demonstrate that metal AM defects follow predictable... Read more

3D characterisation of dry powder inhaler formulations

3D characterisation of dry powder inhaler formulations

Carrier-based dry powder inhaler (DPI) formulations need to be accurately characterised for their particle size distributions, surface roughnesses, fines contents and flow properties. Understanding the micro-structure of the powder formulation is crucial, yet current characterisation methods give incomplete information. Commonly used techniques like laser diffraction (LD) and optical microscopy (OM) are limited due to the assumption of sphericity and can give variable results depending on par... Read more

Investigation on the Fiber Orientation Distributions and Their Influence on the Mechanical Property of the Co-Injection Molding Products

Investigation on the Fiber Orientation Distributions and Their Influence on the Mechanical Property of the Co-Injection Molding Products

In recent years, due to the rapid development of industrial lightweight technology, composite materials based on fiber reinforced plastics (FRP) have been widely used in the industry. However, the environmental impact of the FRPs is higher each year. To overcome this impact, co-injection molding could be one of the good solutions. But how to make the suitable control on the skin/core ratio and how to manage the glass fiber orientation features are still significant challenges. In this study, ... Read more

Tracking tendon fibers to their insertion – a 3D analysis of the Achilles tendon enthesis in mice

Tracking tendon fibers to their insertion – a 3D analysis of the Achilles tendon enthesis in mice

Tendon insertions to bone are heavily loaded transitions between soft and hard tissues. The fiber courses in the tendon have profound effects on the distribution of stress along and across the insertion. We tracked fibers of the Achilles tendon in mice in micro-computed tomographies and extracted virtual transversal sections. The fiber tracks and shapes were analyzed from a position in the free tendon to the insertion with regard to their mechanical consequences. The fiber number was found to... Read more

Cognition based bTBI mechanistic criteria; a tool for preventive and therapeutic innovations

Cognition based bTBI mechanistic criteria; a tool for preventive and therapeutic innovations

Blast-induced traumatic brain injury has been associated with neurodegenerative and neuropsychiatric disorders. To date, although damage due to oxidative stress appears to be important, the specific mechanistic causes of such disorders remain elusive. Here, to determine the mechanical variables governing the tissue damage eventually cascading into cognitive deficits, we performed a study on the mechanics of rat brain under blast conditions. To this end, experiments were carried out to analyse... Read more

Four-Dimensional Studies of Morphology Evolution in Lithium–Sulfur Batteries

Four-Dimensional Studies of Morphology Evolution in Lithium–Sulfur Batteries

Lithium sulfur (Li–S) batteries have great potential as a successor to Li-ion batteries, but their commercialization has been complicated by a multitude of issues stemming from their complex multiphase chemistry. In situ X-ray tomography investigations enable direct observations to be made about a battery, providing unprecedented insight into the microstructural evolution of the sulfur cathode and shedding light on the reaction kinetics of the sulfur phase. Here, for the first time, the mor... Read more
