An experimental and theoretical investigation on microwave plasma-based synthesis of free-standing N-graphene, i.e., nitrogen-doped graphene, was further extended using ethanol and nitrogen gas as precursors. The in situ assembly of N-graphene is a s
Raman spectroscopy of alpha-FeOOH (goethite) near antiferromagnetic to paramagnetic phase transition
Synthetic powder, ore samples, and mineral single crystals of goethite ( α-FeOOH) were investigated with polarized Raman spectroscopy at temperatures from 293 K to 473 K. The symmetry of the vibrational modes, observed in different scattering config
