Contactless health monitoring in autonomous self-reporting ceramic coatings

Autonomous tracking of structural changes in coated components yields information on materials health and remaining lifetime; but until now, electrical resistance tracking required undesired physical connections between coating and readout. Here, the proof ...

Cyclic mechanical response of LPBF Hastelloy X over a wide temperature and strain range: Experiments and modelling

Christian Leinenbach

Additive manufacturing (AM) of high-temperature alloys through processes such as laser powder bed fusion (LPBF) has gained significant interest and is rapidly expanding due to its exceptional design freedom, which enables the fabrication of complex parts t ...

Towards a two-step assessment of the chloride ingress behaviour of new cementitious binders

Karen Scrivener, Fabien Jacques Michel Georget, William Wilson

A wide range of systems were exposed to a seawater-like chloride concentration (0.5 M Cl−) for bulk diffusion experiments over 0.5, 1 and 4 years. Combined with previously published findings on chloride binding and mini-migration testing, the results showe ...

Manufacturing and toughening effects on the material properties of wind turbine blade adhesives

Anastasios Vassilopoulos, Dharun Vadugappatty Srinivasan

Hybrid adhesives can be developed using commercially available adhesive materials and customized to the required loading conditions. In this paper, SPABONDTM 820HTA (non-toughened) and SPABONDTM 840HTA (toughened) adhesives are hybridized by two strategies ...

Skyrmion Control and Phase Transitions in Cu2OSeO3

Thomas Schönenberger

Magnetic skyrmions are nanometric and non-trivial spin textures with non-zero topological charge. Their robustness against perturbations and the possibility to control them using external stimuli make them ideal candidates for future spintronic application ...

Mechanistic Study on Thermally Induced Lattice Stiffening of ZIF-8

Kumar Varoon Agrawal, Wendy Lee Queen, Pascal Alexander Schouwink, Mehrdad Asgari, Qi Liu, Deepu Joseph Babu, Jian Hao

The flexibility of the ZIF-8 aperture, which inhibits a molecular cutoff of 3.4 angstrom, can be reduced by rapid heat treatment to obtain CO2-selective membranes. However, the early stages of the structural, morphological, and chemical changes responsible ...

Modeling peak-aged precipitate strengthening in Al–Mg–Si alloys

William Curtin, Yi Hu

Strengthening by needle-shaped precipitates is critical in Al–Mg–Si alloys. Here, the strengthening is studied computationally at the peak-aged condition where precipitate shearing and Orowan looping are usually considered to have equal strengths. Pseudo-r ...

Internal Friction Phenomena at Polymeric and Metallic Shape Memory Materials. Experimental and Theoretical Results

Maria-Alexandra Paun

The internal friction phenomenon in metallic and polymeric shape memory materials is analyzed. The experimental results permit validation of a theoretical model which describes qualitatively the temperature dependence of the internal friction for the inves ...
