Abstract Visualization and quantification of bone microarchitecture in the human knee allows gaining insight into normal bone structure, and into the structural changes occurring in the onset and progression of bone diseases such as osteoporosis and osteoarthritis. However, current imaging modalities have limitations in capturing the intricacies of bone microarchitecture. Photon counting computed tomography (PCCT) …

Abstract Additive manufacturing (AM) of high-performance structural ceramic components with comparative strength and toughness as conventionally manufactured ceramics remains challenging. Here, a UV-curing approach is integrated in direct ink writing (DIW), taking advantage from DIW to enable an easy use of high solid-loading pastes and multi-layered materials with compositional changes; while, avoiding drying problems. UV-curable …

Abstract Automation through 3D printing can be a possible technological breakthrough in construction. However, the carbon footprint is not necessarily reduced as the print formulations consist of more ordinary Portland cement (OPC) compared to conventional high-performance mortar. In this study, a hybrid mortar with minor amount of OPC and mainly Fe-rich, low-Ca slag is used for printing several structures, …

Abstract 3D nanoparticles are important as reinforcing or functional phase in polymer composite materials; however, an optimised deagglomeration and uniform distribution of these particles is required to fully exploit their nanoscale properties. Classical dispersion methods like shear mixing have proven insufficient, and high-energy ultrasonication, as the preferred deagglomeration method, requires a challenging system-specific optimisation procedure. …

Implementation of a methodology for in-situ 3D characterisation of the crack front in a double cantilever beam test using microfocus X-ray computed tomography

Characterizing the microstructure of an ice/surface interface and its effect on the icephobic behavior of surfaces remains a significant challenge. Introducing X-ray Computed Tomography (XCT) can provide unprecedented insights into the internal (porosity) and interfacial structures

Cryogenic contrast-enhanced microCT enables nondestructive 3D quantitative histopathology of soft biological tissues Biological tissues comprise a spatiallycomplex structure, composition andorganization at the microscale, named the microstructure. Given the closestructure-function relationships in tissues, structural characterization isessential to fully understand the functioning of healthy and pathological tis-sues, as well as the impact of possible treatments. Here, we …

Multiscale modelling of capillary imbibition in 3D-printed porous microfluidic channels   Abstract 3D-printed porous microfluidics has been proposed to realize complex passive lab-on-chips. The performance of these devices depends on capillary flow design and control. To this end, a predictive multiscale model of capillary imbibition in porous channels obtained through powder-based 3D printing was developed. …
