Magnesium has been used as degradable fixation material for osteosynthesis, but it seems that mechanical strength is still a current issue in these fixations. The aim of this study was to evaluate the axial pull-out force of compression headless screws made of magnesium alloy during their resorption. The tests included screws made for osteosynthesi...

Aluminium alloys 7xxx series are widely used in structural components in the aerospace industry as they have high strength at low densities. However, it is well known that in moist-air environments the material fails at lower strengths, and the fracture surface displays macroscopic brittle features attributed to atomic hydrogen, this is known as hy...

In this work, cyclopropylamine (CPA) monomer was plasma-polymerized on poly (ε-caprolactone) nanofiber meshes using various deposition durations to obtain amine-rich surfaces in an effort to improve the cellular response of the meshes. Scanning electron microscopy and X-ray photoelectron spectroscopy (XPS) were used to investigate the surface morph...

Dye coating techniques for colored materials are often cost intensive or cause degradation of the material during processing. Here the authors demonstrate a fast, scalable and cost efficient plasma dye coating procedure, which allows for covalent immobilization of dye molecules on different polymer surfaces.

We investigate the effect of gamma radiation on flux grown KTiOPO4 and Rb:KTiOPO4 samples, as well as their periodically poled variants. Specifically, we study the altered transmission due to color-center formation via gamma irradiation. We measured the transmission of our samples for varying radiation doses and demonstrate effective temperature an...

A new multipactor saturation mechanism is presented for high power microwave devices in the presence of dielectrics. Recent measures have shown that the positive charge deposited on a dielectric as a consequence of the secondary electron emission causes the reduction of its secondary electron yield. This work shows a new multipactor dynamics within...

The interaction between lightning arcs and composite materials is a challenging issue for maintenance and safety considerations in the aerospace industry [1]. Composite materials exhibit a much lower conductivity than metallic materials, as well as an important anisotropy due to the orientation of the fibres and the insulating nature of the matrix....

A martensitic gear steel (18CrNiMo7-6) was annealed at 180 degrees C for 2h and at similar to 750 degrees C for 1h to design two different starting microstructures for shot peening. One maintains the original as-transformed martensite while the other contains irregular-shaped sorbite together with ferrite. These two materials were shot peened using...
