Porous titanium scaffolds produced by powder metallurgy for biomedical applications
(2008-07-01)
Porous titanium scaffolds are promising materials for biomedical applications such as prosthetic anchors, fillers and bone reconstruction. This study evaluated the bone/titanium interface of scaffolds with interconnected ...
Micro-CT scan reveals an unexpected high-volume and interconnected pore network in a Cretaceous Sanagasta dinosaur eggshell
(The Royal Society, 2016-03)
The Cretaceous Sanagasta neosauropod nesting site (La Rioja, Argentina) was the first confirmed instance of extinct dinosaurs utilizing geothermal-generated heat to incubate their eggs. The nesting strategy and hydrothermal ...
Design and 3D bioprinting of interconnected porous scaffolds for bone regeneration. An additive manufacturing approach
(Elsevier B.V., 2021-04-01)
Scaffolds are very important element for bone regeneration issues. On this way, the purpose of this paper is the design and manufacturing of porous scaffolds fabricated by 3D printing technology from biodegradable thermoplastic ...
Porous hydroxyapatite scaffolds by polymer sponge method
(2009-02-02)
This study aimed to develop porous hydroxyapatite scaffold for bone regeneration using the replica of the polymeric sponge technique. Polyurethane sponges were used with varying densities to obtain the scaffolds. The results ...
Digital Light Microscopy of Macroporous Ceramics Processed by Consolidation Casting with Mixtures of Native Starches
(Carl Hanser Verlag, 2008-12-01)
Porosity in starch consolidation casting technique is rightly related to original size and morphology of starch granules, leaving a pore structure after burning out. This work reports the results for the addition of different ...

Preparation of SnO2 supported membranes with ultrafine pores
(Elsevier B.V., 1997-04-30)
The colloidal route of the sol-gel process was used to prepare supported SnO2 membranes. The influence of the sol and monoelectrolyte concentrations on the formation of the gel layer by sol-casting on the top of macroporous ...
Formation of zirconia foams using the thermostimulated sol-gel transition
(Elsevier B.V., 2002-06-01)
In this paper we describe the production of zirconia-based foams by a novel thermostimulated sol-gel route, that employs the foaming of colloidal suspensions prior to the sol-gel transition promoted by small increase of ...
Chitosan and collagen composite for potential application as bone substitute
(2019-03-01)
Purpose: Biopolymers, such as chitosan and collagen, have excellent biocompatibility and can be used for bone remodeling. Chitosan and collagen can be crosslinked by glutaraldehyde. The aim of this study was to formulate ...
