The modifications of properties sub...

Cervical spondylotic myelopathy is a complex syndrome evolving in the presence of degenerative changes. The choice of care and prognostic factors are controversial. The use of appropriate surgical technique is very important. Posterior approach may be chosen when pathology is present dorsally and/or in the presence of neutral to lordotic alignment. Anterior approach is the golden standard in pa...

Polyether-ether-ketone (PEEK) is an alternative to metal alloys in orthopaedic applications. It gives significant advantages including excellent mechanical properties and non-toxicity. In this work, a set of specimens with different notched radii were selected to examine the effect of triaxial state of stress on the fracture behavior of PEEK. Fractographic analysis via scanning electron microsc...

This paper presents a theoretical analysis of the maximum contact stress and the lubrication regimes for PEEK (Polyether-ether-ketone) based self-mating cervical total disc arthroplasty. The NuNec(®) cervical disc arthroplasty system was chosen as the study object, which was then analytically modelled as a ball on socket joint. A non-adhesion Hertzian contact model and elastohydrodynamic lubric...

The work presented here aims at developing a microfluidic device for automated sample enrichment of water samples. The device is optimized for the analysis of small organic pollutants by biosensing and environmental monitoring applications. Miniaturization and automation of solid phase extraction with our device enabled us to reduce the volume of sample and of eluent significantly, resulting in...
