A review on acoustic emission monitoring for damage detection in masonry structures KU Leuven
Acoustic emission monitoring is widely used for damage detection in materials research and for site monitoring. Its use for masonry structures is however challenging due to the highly heterogenic nature of masonry and rapid signal attenuation. However, the non-invasive nature and high sensitivity of the technique also provide interesting opportunities, especially for historical masonry structures, to locate damage, identify severity of damage ...
Autonomous and Active Transport Operated by an Entropic DNA Piston. KU Leuven
We present a synthetic nanoscale piston that uses chemical energy to perform molecular transport against an applied bias. Such a device comprises a 13 by 5 nm protein cylinder, embedded in a biological membrane enclosing a single-stranded DNA (ssDNA) rod. Hybridization with DNA cargo rigidifies the rod, allowing for transport of a selected DNA molecule across the nanopore. A strand displacement reaction from ssDNA fuel on the other side of the ...
A grand-potential based phase-field approach for simulating growth of intermetallic phases in multicomponent alloy systems KU Leuven
Intermetallic phase-based alloys, in particular transition-metal aluminides, are potential structural and coating materials for high-temperature applications. Such applications usually involve interdiffusion between two dissimilar materials. To simulate interdiffusion microstructures quantitatively, it becomes essential to solve alloy phase-field models in conjunction with multicomponent CALPHAD databases. This coupling, however, still remains a ...
Microstructure and mechanical properties of WC and Ti(C0.7N0.3) modified NbC solid solution cermets KU Leuven
Experimental analysis and modelling of mechanical properties and shrinkage of concrete recycling flash calcined dredging sediments KU Leuven
This paper aims to assess the influence of calcined dredging sediments (CFC) from Antwerp port as a new SCM on the mechanical properties and shrinkage behaviour of concrete, where cement is replaced by 20, 30 and 40 wt% of CFC. Experimental results are compared with the current prediction models. CFC blended cement develops lower cumulative heat, compared to an OPC reference mix, resulting in a lower temperature development. Although the ...
