Evaluation of Interface and Residual Strain of NiTi Layer Deposited on NiTiX Substrate by Laser Powder Bed Fusion
Christian Leinenbach, Elyas Ghafoori, Irene Ferretto, Mahbod Golrang, Mahshid Memarian
This study investigates the microstructure and properties of functionally graded NiTi alloy bilayers. The NiTi layer is printed by laser powder bed fusion on a NiTiX (where X is Hf or Cu) substrate prepared by vacuum arc remelting. Specimens produced with ...
Wiley-V C H Verlag Gmbh2024Atomistic simulation and electron microscopy to characterize grain boundaries in doped beta-tricalcium phosphate ceramics
Gabrielle Anne Laguisma Sblendorio
The limitations and potential complications correlated with autogenous bone grafts have raised interest in the development of synthetic bone graft substitutes. ß-tricalcium phosphate (ß-TCP) is one of the most promising materials for synthetic bone graft s ...
EPFL2021edxia: Microstructure characterisation from quantified SEM-EDS hypermaps
Karen Scrivener, Fabien Jacques Michel Georget, William Wilson
The characterisation of cement paste microstructure is an important step towards understanding durability mechanisms in cementitious materials. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) is a widely used technique ...
2020Young's modulus and creep of calcium-silicate-hydrate compacts measured by microindentation
Karen Scrivener, Zhangli Hu, Pietro Lura
In this paper, compacts of synthetic calcium silicate hydrate (C-S-H) with 0.8-1.5 calcium-to-silicon ratio (Ca/Si) and 30-80% porosity were prepared by one-direction cold pressing. The Young's modulus and the creep of C-S-H compacts were measured by micro ...
PERGAMON-ELSEVIER SCIENCE LTD2020A Mini-Atlas of diatom frustule electron microscopy images at different magnifications
Joris Pierre Everaerts, Chrysanthi Papadaki
Diatom algae are active and efficient photosynthesizing single cell organisms responsible for a quarter of biomass and a quarter of oxygen release on the Earth surface. Diatoms form an enormously diverse class of microorganisms possessing stiff and strong, ...
ELSEVIER20205-Fluorouracil Release from Chitosan-Based Matrix. Experimental and Theoretical Aspects
A series of four drug release formulations based on 5-fluorouracil encapsulated into a chitosan-based matrix were prepared by in situ hydrogelation with 3,7-dimethyl-2,6-octadienal. The formulations were investigated from structural and morphological aspec ...

Paul Muralt, Robin Nigon, Silviu Cosmin Sandu, Mohammad Fazel Parsapour Kolour, Lukas Riemer
Sputter deposited A1ScN films with an Sc content of 38 at % were investigated by X-ray diffraction and electron microscopy to study the influence of the radio frequency (RF) bias on the growth of abnormally oriented grains (AOG). Scanning electron microsco ...
2020Experimental And Theoretical Insight Into Formulations Based On Poly(Vinyl Alcohol Boric Acid) And Diclofenac Sodium Salt
A series of three formulations were prepared in view of experimental and theoretical investigation of their drug release potential. The morphology of the film formulations, in terms of distribution of drug into the polymeric matrix and the nature of the dr ...
UNIV POLITEHNICA BUCHAREST, SCI BULL2020Rapid solidification of Al-Cu droplets of near eutectic composition
Near eutectic Al-Cu droplets were rapidly solidified by Impulse Atomization. A wide range of microstructural scales was obtained at different cooling rates and undercoolings. The micrographs of the investigated samples revealed two distinct zones of differ ...
IOP PUBLISHING LTD2019Electric-Field-Mediated Reversible Transformation between Supramolecular Networks and Covalent Organic Frameworks
By using an oriented electric field in a scanning tunneling microscope, one can locally control the condensation of boronic acids at the liquid/solid interface. The phase transition between self-assembled molecular networks and covalent organic frameworks ...
