A novel, environmentally friendly, fast, and flexible polishing process for Nitinol parts is presented in this study. Nitinol samples with both superelastic and shape memory properties at room temperature were investigated. The chemical contamination

By use of inelastic neutron scattering we have studied magnetic fluctuations in 8-nm particles of antiferromagnetic alpha-Fe2O3 (hematite) as a function of temperature and applied magnetic fields. The fluctuations are dominated by uniform excitations

We show that antiferromagnetic nanoparticles of alpha-Fe2O3 (hematite) under wet conditions can attach into chains along a common [001] axis. Electron microscopy shows that such chains typically consist of two to five particles. X-ray and neutron dif
