The γ-Fe2O3 nanoparticles coated with DBS and CTAB were prepared by the microemulsion method.The coated samples show enhanced nonlinear optical properties comp
There are two tpyes of phase transformations in Fe-Mn and Fe-Mn-Si alloys when the temperature is decreased,γ(fcc)→ε(hcp) martensitic transformation(MT) and
Extended x-ray-absorption fine-structure measurements(EXAFS) were performed on nanocrystalline (nc) elemental Se samples with grain sizes ranging from 13 to 60
