Development of filled polymers for the replacement of ceramics used as ballistic protection layer
Ceramics have extensively been used for ballistic protection in the last decades. The combination of their mechanical properties makes them very interesting for armouring. Indeed, they exhibit a high hardness, large compression strength, high stiffness and low density. Ceramic armouring plates are …

Numerical model to simulate the Ti(C,N) protection layer in the blast furnace hearth
It is well understood that the erosion of the hearth refractories is by part a major limitation of the longevity of the blast furnace. Addition of titania via burdening or tuyere injection increases the titanium content in the molten pig iron and is believed to promote the so-called titanium-rich …

Compliant Epitaxy of Iii-V Compound Semiconductors for Optoelectronic Device Applications
… In addition, VLTMBE-grown InGaP was used as a protection layer during post-growth oxidation processes. These InGaP layers were used to protect the In0.25Ga0.75As layers, mentioned above, during the lateral oxidation relaxation process. The VLT-grown InGaP films were found to be superior to …

Integrating security services into computer supported cooperative work
… secure access control service and an information protection service. These security services are implemented as a protection layer for the groupware system. These layers are called External Security Layer (ESL) and Internal Security Layer (ISL) respectively. The security services are sufficiently …

Ageing of HDPE Geomembranes Used to Contain Landfill Leachate or Hydrocarbon Spills
… a comparison of ageing with three different “protection” layers between the GM and overlying gravel and leachate is reported. A slower antioxidant depletion rate is observed when geotextile-geosynthetic clay liner and geotextile-sand-geotextile are applied than with a typical geotextile alone. …

Calculating and Limiting Local Strains in Geomembranes From Gravel Indentations
… the compressibility of the underlying clay layer, particle size of the overlying gravel, and mass of the geotextile protection layer influence local geomembrane strains. Results are provided that can be used to rule out protection layers that are unable to meet a long-term strain limit, and …

NOVEL NANOMATERIALS FOR ENERGY RELATED APPLICATIONS
… reported. The coatings successfully served at a protection layer by limiting oxygen penetration, sulfur attack, and decreased the formation of pits and cracks on the substrates at 750°C for up to 800 hours. In chapter 3, continuous smooth TiC nanofibers were successfully synthesized by …

Dye sensitized solar cells: optimization of Grätzel solar cells towards plasmonic enhanced photovoltaics
… for further improvement. Optimized single layer GSCs and double layer GSCs showing efficiencies >4% and efficiencies of ~6%, respectively, were obtained. Recently, the incorporation of metallic nanoparticles into silicon solar cells has shown improved efficiency and lowered material cost. …
