Role of in-flight temperature and velocity of powder particles on plasma sprayed hydroxyapatite coating characteristics by Cizek, Jan, Khor, Khiam Aik

“…Joint incidence of both in-flight properties was found to significantly influence the microstructure of the coatings and its respective surface roughness levels (Ra = 7.4–19.4 μm). The morphology of impinging splats was found to be influenced by both the in-flight velocity (dominant factor) and temperature (secondary factor) of the HA particles.…”

Emergent vortices at a ferromagnetic superconducting oxide interface by Petrović, A P, Paré, A, Paudel, T R, Lee, K, Holmes, S, Barnes, C H W, David, A, Wu, T, Tsymbal, E Y, Panagopoulos, C

“…This hysteresis is argued to arise from vortex depinning within a thin (< 20 nm) superconducting layer, mediated by discrete ferromagnetic dipoles located solely above the layer. The pinning strength may be modified by varying the superconducting channel thickness via electric field-effect doping. …”
