Summary: A versatile pilot-scale reactor has been designed to convert between dielectric barrier discharge PECVD and photoinitiated PICVD modes, both using acetylene monomer under low pressure conditions. Efficient gas-to-solid conversion into nanoparticulate amorphous hydrocarbon polymer-like material was achieved, with the need to carefully exclude O-2 contamination in the latter mode to avoid oxidation issues.

Summary: PECVD processes are widely used in the synthesis of organic or inorganic thin films on various substrates. However, it is challenging to fabricate tailor-made materials for specific applications due to the complexity of the process. Mastery of the technique requires a fundamental understanding of the chemical and physical phenomena involved in film formation.

Summary: In this study, tungsten coatings were deposited at 300-610 degrees C from WF6 and H-2 by atmospheric pressure chemical vapor deposition (APCVD). It was found that regardless of the density of the coating, tungsten powders adhered to the furnace walls. These powders were produced by homogeneous reactions in the gas phase near the substrate and adhered to the inner wall of the furnace as they moved with the fluid. The study discussed the kinetics, structure, and growth mode of tungsten coatings in the APCVD system, highlighting the contributions of homogeneous reactions to the growth of dense tungsten coatings.

Summary: This investigation demonstrates the pitfalls of surface contaminations on polymer blends in adhesive joints and presents Extended Non-Destructive Testing (ENDT) as a solution. The study shows that greasy fingerprints on ABS substrates had little effect on initial joint strengths, but resulted in significant strength reduction after accelerated aging. The study recommends incorporating the intended use into quality requirements and implementing in-process ENDT procedures, such as the Aerosol Wetting Test (AWT), to ensure adhesive application on high-quality substrates.

Summary: The study found that the geometry of the nozzle head has a significant impact on the energy flux, while the relaxation volume affects the dependence of the energy flux on the gas flow. Without a relaxation volume, the working gas flow does not significantly influence the energy flux, but using a relaxation volume leads to a decrease in energy flux with increasing working gas flow. Within the analyzed parameter range, the energy flux shows a linear dependency on the applied primary voltage for both nozzle heads.
