X-ray scattering characterisation of nanoparticles (2015, methodology): “The size and strain behaviour of CeO2 nanoparticles 4–60 nm in size were studied by Zou and Huebner.[79] From Williamson–Hall plots, they found that the smallest nanoparticles (4 nm) did not exhibit any internal strain (slope = 0), while larger particles (12 and 60 nm) showed a significant strain, w”
Nanocrystalline indium oxide-doped tin oxide thin film as low temperature hydrogen sensor (2004, background): “The excess lattice oxygen-ion vacancy concentration, below a critical nanocrystallite size, has also been predicted for other ceramic oxides [47,48].”
