Revision surgeries of total hip arthroplasty are often caused by a deficient structural compatibility of the implant. Two main culprits, among others, are bone-implant interface instability and bone resorption. To address these issues, in this paper we propose a novel type of implant, which, in contrast to current hip replacement implants made of either a fully solid or a foam material, consist...

In the present work, six-layered (Zirconia/Nickel) functionally graded materials were fabricated via powder metallurgy technique (PMT). The microstructure, fracture surface and the elemental analysis of the prepared components were studied, and their linear shrinkage, electrical conductivity, fracture toughness and Vickers hardness were evaluated. The results show that the linear shrinkage of t...

Herein, a comparative study of the electromagnetic interference (EMI) shielding performance multi-layered architectures fabricated using different strategies ( i.e. , polyurethane (PU)-based film, foam, and 3D printed structures) has been evaluated.

A novel ultra-lightweight three-dimensional (3-D) cathode system for lithium sulphur (Li-S) batteries has been synthesised by loading sulphur on to an interconnected 3-D network of few-layered graphene (FLG) via a sulphur solution infiltration method. A free-standing FLG monolithic network foam was formed as a negative of a Ni metallic foam template by CVD followed by etching away of Ni. The FL...

Abstract We present an experimental study of the dynamics shocks generated by interaction a double-spot laser in different kinds targets: simple aluminum foils and foam–aluminum layered targets. The experiment was performed using Prague PALS iodine working at 0.44 μm wavelength irradiance few 10 15 W/cm 2 . Shock breakouts for pure Al foam-Al targets have been recorded time-resolved self-emissi...
