Geothermal silica, another potential source of amorphous silica, commonly forms as precipitate in pipes and on other surfaces at geothermal power plants where water supersaturated with silicic acid (i.e., geoth
For the remaining real silicon oxide surfaces the oxygen bonding is more complex with a certain similarity between the O KLL spectra and the corresponding spectra of SiO2. Recognized changes in the O KLL lineshapes cannot be explained within a mixture model, but by a random bonding model or ...
The arrangement of the test specimen on the test stand with its 1.5 m high vertical surfaces in an inner corner also corresponds to the real situation on a façade. The exposure scenario of the gas burner as a base fire is also similar to the principle of a façade fire. All tests ...
It was also reported that the ion-beam treat- ment was capable of providing HA-coated titanium bioimplants with hardened surfaces, and thus improved the wear resistance [29]. An essential element for the human body, phosphorus, can be implanted on titanium-based biomaterials via ion-beam ...
Primary explosives such as triacetone triperoxide (TATP) has one of the highest vapour pressures (~10−5 atm at 25 °C) and traces readily evaporate from surfaces over relatively short periods of time, potentially making it easier to detect in the vapour phase. In contrast, components ...
RESULTS: (1) The dimension of the CAJ cavity was much larger than the articular surfaces; (2) The posterior capsule of the CAJ was significantly strengthened, contained rich elastin fibers, and shared a common attachment with the posterior cricoarytenoid muscle; (3) The arytenoid cartilage ...
Limitations also exist regarding modelling approaches for processes, such as incidental exposure by splashes, contact with contaminated surfaces, deposition of airborne substances on the skin [37] and subsequent uptake into different skin layers [22]. However, recent efforts have been made to advance ...
The Surface and Line Style dialog box is used to customize the appearance of lines or surfaces. The used XY Cut Lines are in two directions. The number of cuts in the grid has to be specified by the number of bins i′ (or j′ respectively) minus 1 in the data set. For example, ...
Processing powders produced primarily for thermal spraying resulted in significantly higher roughness and inhomogeneous layers. In particular, Amperit 515.001 displayed highly uneven areas where particles accumulated or were missing. Non-spherical particles resulted in numerousfriction surfacesandentanglementpossibil...
78c. The access aperture81forms an angle of aperture of at least α=30° or possibly at least 45°. Unlike the example shown, one can minimize the intrusion of the bearing surfaces for movable components, such as the support disc77or the covers84, into the access aperture81(such a ...
