Nano-Material Aspects of Shock Absorption in Bone Joints

Nano-Material Aspects of Shock Absorption in Bone Joints

This theoretical study is based on a nano-technological evaluation of the effect of pressure on the composite bone fine structure. It turned out, that the well known macroscopic mechano-elastic performance of bones in combination with muscles and tendons is just one functional aspect which is critically supported by additional micro- and nano- shock damping technology aimed at minimising local ...

Moisture absorption-desorption effects in adhesive joints

This paper presents a study of moisture absorption-desorption effects in single lap adhesive joints. Experiments were carried out to characterise the moisture uptake of the single part epoxide adhesive, FM73. Tensile testing of single lap joints manufactured from aluminium alloy 2024 T3 and O and FM73 adhesive was carried out after the joints were exposed to different conditioning environments....

Nano-TiO2/PEEK bioactive composite as a bone substitute material: in vitro and in vivo studies

BACKGROUND Compared with titanium (Ti) and other metal implant materials, poly(ether-ether ketone) (PEEK) shows outstanding biomechanical properties. A number of studies have also reported attractive bioactivity for nano-TiO(2) (n-TiO(2)). METHODS In this study, n-TiO(2)/PEEK nanocomposites were prepared, taking advantage of the unique properties of both PEEK polymer and n-TiO(2). The in vitr...

Nano-Energetic Material Decomposition Processes

Motivation It has been recognized by many within the energetic materials community that the use of nano-sized energetic particles can lead to substantial increases in overall performance and safety of energetic materials. Nano-sized energetic particles offer the potential of high heat release rates, increased combustion efficiencies, tailored burning rates, and reduced sensitivity. In order to ...
