High cycle tensile fatigue behavior of steel rebar reinforced - UHPFRC at high R-ratio

Eugen Brühwiler, Alain Nussbaumer, Jian Zhan

This paper investigates the high cycle tensile fatigue behavior of steel rebar reinforced − UHPFRC elements, at a fatigue load ratio, i.e., R-ratio of 0.3, representative for structural applications. Prior to testing, magnetoscopy is conducted on each spec ...

Tailoring mechanical properties and microstructures in laser powder bed fusion of 316 L stainless steel through aluminium alloying and combined ex-situ and in-situ heat treatments

Roland Logé, Cyril Cayron, Claire Navarre, Seyed Amirmohammad Jamili, Maxence Jean Gabriel Buttard

Laser powder bed fusion (LPBF) is a bottom-up manufacturing technique using a high-energy laser to selectively melt metallic alloys, enabling the creation of complex microstructures. While rapid cooling rates and process stochasticity can lead to unpredict ...

Optical tweeze-sectioning microscopy for 3D imaging and manipulation of suspended cells

Xiaohao Xu, Olivier Martin, Siarhei Zavatski

Optical manipulation and detection of biological particulates are crucial procedures in biophotonics. Optical sectioning (OS) opens the avenue to three-dimensional (3D) microscopy, but nonoptical approaches, including sample adhesion and mechanical scannin ...

Effect of temperature on apparent crack arrest toughness of Eurofer97 measured by a newly developed small specimen test technique

Philippe Spätig

Neutron embrittlement of in -core and out-of-core components made of ferritic steels is one of the key parameters limiting the life of power plants. Owing to the small volume of available irradiation facilities and the limited number of neutron-irradiated ...

Optical imaging of molecules and their dynamics from surfaces to nanoscale confinement

Nathan Cyprien Arsène Ronceray

Molecular behavior can change dramatically at interfaces, and these changes become even more pronounced when molecules are confined within nanoscale dimensions. In living organisms, nanoscale channels play a crucial role in selectively transporting molecul ...

Direct Observation of the Phase Transition in C60 Fullerene

Chengcheng Yan

In the third study, the order-disorder phase transition of single-crystal C60 is studied using time-resolved electron microscopy. Solid C60 undergoes a first-order phase transition upon heating to 260 K. This is a structural transition from the low-tempera ...

Correlative Light, Electron Microscopy and Raman Spectroscopy Workflow To Detect and Observe Microplastic Interactions with Whole Jellyfish

Gaëlle Delphine Toullec, Niclas Heidelberg Lyndby

Many researchers have turned their attention to understanding microplastic interaction with marine fauna. Efforts are being made to monitor exposure pathways and concentrations and to assess the impact such interactions may have. To answer these questions, ...

Focus image scanning microscopy for sharp and gentle super-resolved microscopy

Giorgio Tortarolo

To date, the feasibility of super-resolution microscopy for imaging live and thick samples is still limited. Stimulated emission depletion (STED) microscopy requires high-intensity illumination to achieve sub-diffraction resolution, potentially introducing ...

High-performance polyamides with engineered disorder

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Nicolas Candau, Sylvain Cyril Claude Galland, Julien Philippe Cretenoud

The extraordinary property profiles of many biological materials derive from their hierarchical structure and control of order and disorder at different length scales. Application of these concepts to the design of synthetic polymers may provide new routes ...
