Micro-chemo-mechanical features of ultra-high performance glass concrete (UHPGC)

The development of Ultra-High Performance Concrete (UHPC) opened new research directions for enhancing the architectural design, sustainability and serviceability of concrete structures. However, the costs and resource intensiveness trigger the need for in ...

Kinetics of mixing-water repartition in UHPFRC paste and its effect on hydration and microstructural development

Eugen Brühwiler, Karen Scrivener, Emmanuel Denarié, Arnaud Charles Albert Muller, Mohammadhadi Kazemi Kamyab

The hydration of an ultra-high performance fibre reinforced concrete (UHPFRC) paste with a water to cement ratio of 0.18 was followed by proton nuclear magnetic resonance (1H NMR) alongside more classical techniques for hydration kinetics, and microstructu ...

Nanoscale Depth Profiling of Residual Stresses Due to Fine Surface Finishing

Joris Pierre Everaerts

Mechanical polishing is commonly used for both surface finishing and metallographic sample preparation for a broad range of materials. However, polishing causes local deformation and induces residual stress, which has an important effect on many surface ph ...

The Influence of Microstructure on Nanomechanical and Diffusion Barrier Properties of Thin PECVD SiOx Films Deposited on Parylene C Substrates

Ivo Furno, Yves Leterrier, Matthias Van Gompel, David Framil Carpeno

Plasma-enhanced chemical vapor deposition (PECVD) was used to deposit SiOx thin films of varying thicknesses on parylene C substrates, using hexamethyldisiloxane (HMDSO) as a precursor. The microstructure of SiOx coatings was analyzed using X-ray photoemis ...

Learning global brain microstructure maps using trainable sparse encoders

Jean-Philippe Thiran, Gabriel Girard, Jonathan Rafael Patino Lopez, Alessandro Daducci, Muhamed Barakovic

Diffusion-Weighted Magnetic Resonance Imaging is the only non-invasive technique available to infer the underlying brain tissue microstructure. Currently, one of the promising methods for microstructure imaging is signal modelling using convex formulation, ...

Impact of temperature on expansive behavior of concrete with a highly reactive andesite due to the alkali-silica reaction

Karen Scrivener, Cyrille Dunant

The influence of temperature on the expansive behavior and microstructural damage of concrete due to the alkali-silica reaction (ASR) is studied experimentally by applying a new testing protocol, the Alkali-Wrapped Concrete Prism Test (AW-CPT). Early-stage ...

Dissipative particle dynamics simulations of tri-block co-polymer and water: Phase diagram validation and microstructure identification

Ignacio Pagonabarraga Mora

In this study, the phase diagram of Pluronic L64 and water is simulated via dissipative particle dynamics (DPD). The peculiar structures that form when the concentration varies from dilute to dense (i.e., spherical and rod-like micelles, hexagonal and lame ...

Effect of laser rescanning on the grain microstructure of a selective laser melted Al-Mg-Zr alloy

Christian Leinenbach

The microstructures of alloys created via Additive Manufacturing (AM) can vary substantially from those present in cast or wrought products, due to the very rapid solidification associated with AM. While numerous studies have investigated the process-micro ...

Validation strategies for the interpretation of microstructure imaging using diffusion MRI

Giorgio Innocenti, Tim Bjørn Dyrby

Extracting microanatomical information beyond the image resolution of MRI would provide valuable tools for diagnostics and neuroscientific research. A number of mathematical models already suggest microstructural interpretations of diffusion MRI (dMRI) dat ...

The double-edge effect of second-phase particles on the recrystallization behaviour and associated mechanical properties of metallic materials

Roland Logé, Ke Huang

Most industrial alloys contain a matrix phase and dispersed second-phase particles. Several thermomechanical processing (TMP) steps are usually needed to produce a final product, during which recrystallization and its related phenomena may take place. Seco ...
