Topological derivative-based optimization of micro-structures considering different multi-scale models
(Tech Science Press, 2010)
A recently proposed algorithm for micro-structural optimization, based on the concept of topological derivative and a level-set domain representation, is applied to the synthesis of elastic and heat conducting bi-material ...
Micro arc oxidation of Ti-15Zr-7.5Mo alloy
(2016-01-01)
Ti-15Zr-7.5Mo alloy was melted and its structure and mechanical properties were evaluated, followed by micro-arc oxidation (MAO) treatment to add bioactivity. Melted Ti-15Zr-7.5Mo alloy was consisted of mainly β containing ...
Electrical and micro structural properties of (Zn, Nb, Fe)-doped SnO2 varistor systems
(Elsevier B.V., 2005-01-01)
The electrical and microstructural properties of SnO2-based varistors with the addition of 0.025 and 0.050 mol% of Fe2O3 have been characterised. Electric field (E) versus current density (J) curves showed that the effect ...

Connecting biology, optics and nanomechanical properties in micro-wasps
(2020)
Coloration in insects provides a fruitful opportunity for interdisciplinary research involving both physics and biology, and for a better understanding of the design principles of biological structures. In this research ...
Influence of ceria addition on thermal properties and local structure of bismuth germanate glasses
(ELSEVIER SCIENCE BV, 2010)
Bismuth germanate glasses are interesting materials due to their physical properties and their unique structural characteristics caused by the coordination changes of bismuth and germanium atoms. Glasses of the bismuth ...
Dielectric and non-ohmic properties of Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤4.0) multiphasic ceramic composites
(2018-02-25)
Multiphasic Sn4+ substituted Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤ 4.0) ceramic composites were prepared by solid-state reaction. Their crystalline structure, microstructure, dielectric and non-ohmic properties were investigated. ...
Numerical study of damaged micro-lattice blocks subjected to uniaxial compressive loading
(Elsevier, 2020-09)
This article presents a numerical study on the mechanical behaviour of damaged micro-lattice (ML) blocks submitted to uniaxial compressible loads. The numerical model is implemented in the commercial finite-element code ...
Is there any information on micro-structure in microwave tomography of bone tissue?
(Elsevier, 2013-08)
In this work, two-dimensional simulations of the microwave dielectric properties of models with ellipses and realistic models of trabecular bone tissue are performed. In these simulations, finite difference time domain ...
