Hard and wear-resistant coatings created utilizing physical vapor deposition (PVD) techniques are extensively used in extreme tribological applications. The friction wear behavior of vary significantly with temperature, indicating that advanced coating concepts essential for prolonged load-bearing Many have recently been explored this area, including multicomponent, multilayer, gradient coating...
We investigated single shot damage of Mo/Si multilayer coatings exposed to the intense fs XUV radiation at the Free-electron LASer facility in Hamburg - FLASH. The interaction process was studied in situ by XUV reflectometry, time resolved optical microscopy, and "post-mortem" by interference-polarizing optical microscopy (with Nomarski contrast), atomic force microscopy, and scanning transmiss...
Ice propagation is of great importance to the accumulation of ice/frost on solid surfaces. However, no investigation has been reported on the tuning of ice propagation through a simple coating process. Herein, we study the ice propagation behavior on polyelectrolyte multilayer (PEM) surfaces coated with the layer-by-layer (LBL) deposition approach. We discover that ice propagation is strongly d...
Recent developments in thin-film coatings for optical communication systems are reviewed. Particular emphasis is given to thin-film designs with dispersion related to the photonic crystal superprism effect. A single dispersive coating may be used for multiplexing or demultiplexing several wavelength channels by spatial beam shifting. 2004 Optical Society of America OCIS codes: (310.0310) Thin ...
The sequential deposition of chitosan and pectin on a supported phospolipid bilayer was examined using a quartz crystal microbalance. Multilayer formation was observed. The coating of phospholipid-stabilized emulsion droplets through centrifugation in a stepped sucrose gradient, containing successive layers of pectin and chitosan, was then investigated. Microelectrophoresis of the emulsion drop...
TiO2 films are extensively studied because of their interesting chemical, electrical and optical properties. TiO2 is a high bandgap semiconductor that is transparent to visible light and has excellent optical transmittance. TiO2 has high refractive index and good insulating properties, and as a result it is widely used as protective layer for very large scale integrated (VLSI) circuits and for ...
