Mechanical Reinforcement of Hydrogels through Physical Crosslinks and Double Network Granular Architecture

Throughout nature, organisms fabricate a myriad of materials to sustain their lifestyle. Many of the soft materials are composed of water-swollen networks of organic molecules, so-called hydrogels. They generally contribute to the mechanical integrity of t ...

Integration of hybrid material systems in conformable neural interfaces

Florian Dylan Fallegger

Neural interfaces are devices that are implanted into the body and interface electrically with the central (CNS) or peripheral nervous system. They are inserted surgically for short periods of time or chronically to diagnose or treat several neural disease ...

Bio-inspired design and validation of the Efficient Lockable Spring Ankle (ELSA) prosthesis

Mohamed Bouri, Renaud Ronsse, Bruno Dehez, François André Heremans

Over the last decade, active lower-limb prostheses demonstrated their ability to restore a physiological gait for transfemoral amputees by supplying the required positive energy balance during daily life locomotion activities. However, the added-value of s ...

Adsorption of HPDX and CaHPOx (x=1, ...,4) molecules on anatase TiO2 (001) surfaces

Michel Posternak

perform DFT calculations within the COSMO framework to study the adsorption properties of the CaHPOx (x = 1,...,4) phosphate family, and of the related HPOx acids, on a paradigmatic anatase (001) surface. Of particular interest is CaHPO4, a precursor of hy ...

Rapid evaluation of bioactive Ti-based surfaces using an in vitro titration method

Paul Bowen, Jacques Lemaître, Weitian Zhao

The prediction of implant behavior in vivo by the use of easy-to-perform in vitro methods is of great interest in biomaterials research. Simulated body fluids (SBFs) have been proposed and widely used to evaluate the bone-bonding ability of implant materia ...

Development of a simulated transtibial amputee model

Auke Ijspeert, Florin Dzeladini, César José Cardoso Ferreira

Currently, there are more than 30 million amputees in the world and each year thousands of people suffer from amputation and, therefore, the development of lower limb prostheses is crucial to improve the quality of millions of people's lives by restoring t ...

Fractal Analysis And Related Forms Of Complexity Of Embryo Development. Is There A New Tool For Human Embryo Selection?

Maria-Alexandra Paun

A total number of 1092 embryos, originated from 168 couples that underwent IVF cycles, were analyzed in this study. The embryos were cultivated in a continuous culture and monitored using the time lapse system EmbryoScope. The microscopic images of the fer ...

Knee Implant Loosening Detection: A Vibration Analysis Investigation

Kamiar Aminian, Arash Arami, Hossein Rouhani

Knee implant loosening is mainly caused by the weakness of the prosthesis-bone interface and is the main reason for surgical revisions. However, pre-operative diagnosis is difficult due to lack of accurate tests. In this study, we developed a vibration-bas ...

Fiber density of collagen grafts impacts rabbit urethral regeneration

Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda, Ganesh Vythilingam

There is a need for efficient and “off-the-shelf” grafts in urethral reconstructive surgery. Currently available surgical techniques require harvesting of grafts from autologous sites, with increased risk of surgical complications and added patient discomf ...

Calcium phosphate formation on titanium-based surfaces: bioactivity evaluated by in vitro methods

Weitian Zhao

The prediction of implant behaviors in vivo by the use of easy-to-perform in vitro methods is of great interest in biomaterials research. In the field of bone implants, it is commonly accepted that a spontaneous formation of a hydroxyapatite (HA) layer on ...
