Plasma dye coating as straightforward and widely applicable procedure for dye immobilization on polymeric materials
...
Here, we introduce a novel concept for the fabrication of colored materials with significantly reduced dye leaching through covalent immobilization of the desired dye using plasmagenerated surface radicals. This plasma dye coating (PDC) procedure immobilizes a preadsorbed layer of a dye functionalized with a radical sensitive group on the surface t...
Gamma irradiation-induced absorption in single-domain and periodically-poled KTiOPO_4 and Rb:KTiOPO_4
We investigate the effect of gamma radiation on flux grown KTiOPO 4 and Rb:KTiOPO 4 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 ...
New multipactor dynamics in presence of dielectrics
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...
Simulation of the Lightning Arc Root Interaction with Anisotropic Materials
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....

Numerical modelling and computer simulations
The development of armour materials and systems is a very expensive business, especially when it involves lengthy ballistic trials. Penetration and perforation events are also highly complex and involve competition between alternative failure mechanisms. The physical conditions within an impact zone also vary, with location, in temperature, strain-...
Effect of shot peening on the residual stress and mechanical behaviour of low-temperature and high-temperature annealed ...
...
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...
Crack mitigation in concrete : superabsorbent polymers as key to success?
Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous an...
