SiC ceramic micropatterns from polycarbosilanes

Temperature-dependent dielectric and microwave absorption properties of SiC /SiC–Al2O3 composites modified by thermal cross-linking procedure

“…While after cross-linking, the EDS analysis shows a relative high oxygen content of 42.4%, indicating the introduction of massive oxygen. During the thermal cross-linking, the PCS will contact with air and amounts of oxygen can be introduced according to the following reaction [30,31]:…”

Si–Zr–C–N-based hydrophobic plasma polymer membranes for small gas molecule separation

“…4. There were five vibrational bands at 3360 cm −1 , 2900 cm −1 , 2160 cm −1 , 976 and 885 cm −1 that were attributed according to the literature to ν N-H, ν C-H, ν Si-H, ν Si-N and δ Si-C bonds, respectively [21,24,25].…”

Fabrication of Silicon Carbide Micropillar Arrays from Polycarbosilanes

“…In the absence of capillary forces (e.g., no liquid contact bridging), van der Waals forces become dominant for the adhesion between the pillars. Although the van der Waals forces are typically in the range of <100 nN, 32 the low stiffness of cross‐linked PCS (Young's modulus E of approximately 2.5 GPa) 7 facilitates micropillar bending. Bending of the free‐standing pillars of length l due to van der Waals adhesion force, F vdW , results in a deflection , which at a given point l z from the base is expressed by 31 where E is the elastic modulus and I is the moment of inertia.…”
