TL;DR: Fundamental aspects of porous HA for artificial bone applications as well as various techniques used to prepare porous HA are discussed, some of the recent results on development of porous ha will be presented.

TL;DR: In this paper, the properties of porous hydroxyapatite (HA) bioceramic produced by heat treatment (annealing) of bovine bone were evaluated over temperatures between 400°C and 1200°C.

TL;DR: In this article, the effects of grain size on the relative density and hardness of sintered hydroxyapatite compacts were investigated and the change in hardness was found to be dependent on the grain size.

TL;DR: In this article, a computationally aided design process of a thin wall structure subject to dynamic compression in both axial and oblique directions was described, which was further enhanced for better crash performances by investigating the effect of foam filling, increasing the wall thickness and by introducing a trigger mechanism.

TL;DR: In this paper, the micro-structure analyses of the geopolymer specimens and comparison of geopolymers with various binders are presented. But, most of the products revealed a wide hump in the XRD analysis due to the amorphous structure of aluminosilicate, and the results showed that the binders mixed with lower sodium silicate to sodium hydroxide mass ratio of 2.0-2.5 tend to react more efficiently.
