Summary: This paper examines a new approach for synthesizing Parylene-metal multilayers. The metal layers are obtained from a metal salt solution and a plasma reduction treatment. This one-pot synthesis process requires less resources and energy compared to electron beam sputtering processes. The Parylene coatings are obtained after plasma treatments with Parylene C. The process provides ultra-thin metal salt layers and Parylene layers with good tensile strength and wettability.

Summary: A novel method for improving thermal stability and adhesion of Parylene C is proposed by copolymerizing it with Parylene F. The successful preparation of copolymer films with different ratios of Parylene C and Parylene F is confirmed. The copolymer film exhibits an adhesion 10.4 times stronger than that of the Parylene C homopolymer film. The friction coefficients and cell culture capability of the copolymer films show no degradation compared to the Parylene C homopolymer film.

Summary: The thermal properties of SiO2 aerogels made from waterglass and TEOS were studied before and after coating with parylene using thermal and plasma deposition methods. The specific surface area of the aerogels was reduced after thermal deposition of parylene coating, while the reduction was smaller with plasma deposition. The thermal conductivity of the aerogels decreased after plasma deposition, indicating improved thermal insulation. However, the thermal conductivity changed in the opposite direction after thermal deposition. The deposition method of parylene had a significant impact on the thermal properties of the SiO2 aerogels.

Summary: Cu-precipitation in reactor pressure vessel steels is a major concern for the degradation of mechanical properties. This study develops and implements a non-local phase-field model to investigate the equilibrium morphology of precipitates in the over-aged state. The model confirms that the precipitates should have an oblate lath-like shape, which is supported by experimental data. The orientation of the precipitates is consistent with literature. The mechanism of morphology accommodation is explained using the invariant-line method. However, the equilibrium values of elongation significantly deviate from experimental data, likely due to the metastable state of the precipitates during the coarsening process.
