Physical vacuum deposition, sputtering

PEEK is a medical grade material which is increasingly used instead of titanium in osteosynthesis and joint replacement. However, its surface properties of PEEKlack on an adequate osteoconductivity. In this study, two coatings with different architectures composed of Ti, Mg and Ag were prepared by physical vacuum deposition to be used in spinal implants. The mechanical durability of the coatings is investigated in terms of their tribological behaviour.

Staphylococcus aureus is a bacterium which people have been in contact with for thousands of years. Its presence often leads to severe disorders of the respiratory and circulatory systems. The authors of this article present a prototype of a textronic sensor enabling the detection of this bacterium. This sensor was created using a process of physical vacuum deposition on a flexible textile substrate which can be implemented on clothing. With increasing numbers of bacterial colonies, changes in the sensor’s electrical parameters were observed. The sensor’s resistance reduced by 50% and the capacitance more than doubled within the first two days of starting bacterial cultures. Extensive changes in electrical parameters were observed at 100 Hz and 120 Hz of the measurement signal.

AbstractIn this paper, the authors describe the distribution of temperatures around electroconductive pathways created by a physical vacuum deposition process on flexible textile substrates used in elastic electronics and textronics. Cordura material was chosen as the substrate. Silver with 99.99% purity was used as the deposited metal. This research was based on thermographic photographs of the produced samples. Analysis of the temperature field around the electroconductive layer was carried out using Image ThermaBase EU software. The analysis of the temperature distribution highlights the software’s usefulness in determining the homogeneity of the created metal layer. Higher local temperatures and non-uniform distributions at the same time can negatively influence the work of the textronic system.

Smoke Particles

Fine-structure in spotty electron diffraction riiig patterns has previously been observed for specimens made up of MgO smoke particles of cubic morphology. This fine-structure was shown to arise from refraction effects in the small cubes (Sturkey & Frevel). We have recently observed a different type of fine structure in patterns from MgO films prepared by vacuum deposition (Fig. 1). This fine-structure consists of sets of regularly spaced fringes occurring at random orientations in the rings. The fringes may be seen in Fig. 2 which shows a segment of the (200) ring magnified 7x from the pattern in Fig. 1. It was considered possible that each set of fringes might arise from two superimposed diffraction’ spots from suitably situated crystallites in the specimen. Experiments have been conducted which clearly demonstrate that the fringes do in fact arise in this way.
