He reported that the epitaxial nucleation and growth of rutile TiO2 nanorods on FTO occurred because the FTO substrate and the rutile TiO2 both had tetragonal rutile structures and the lattice mismatch between the tetragonal FTO and the TiO2 was very small ( only ~ 2%).

Abstract.
The HAp ceramics have been usually prepared by solid state reaction at high temperatures above 1000°C [1-4], which results in removal of the hydroxyl ions from the HAp structure and may cause the decrease of bioactivity.

For understanding the structure of corrosion scale, XPS is used to survey the chemical state of
element species, and only iron, molybdenum and sulfur are identified on the outer surface of the
scale.

Abstract.
The higher SEAS for Pt-Ru@PANI-MWNT catalyst is attributed to the unique conducting network structure of PANI on the surface of MWNT as well as due to the large amount of Ru content.

Abstract
Quasi-one-dimensional sulfide BaVS3 is known to show a metal-to-semiconductor transition at ~70
K.
Introduction BaVS3 has a quasi-one-dimensional structure with space group of P63/mmc above ~240 K, characterized by linear chains of V +4 (3d 1 configuration) running parallel to the c axis [1].

Abstract.
For the E//c polarization the structure of the PL spectra differs; we should notice some excited state at 5.4 (*i) and 2.6 meV (*j) higher in energy that the Ph b line, and the two distinct lines at 5.7 (*k) and 6.9 (*l) meV lower energy than the Ph b line were not observed in all our samples. 4H polytype At low temperature the spectrum recorded (with E⊥c polarization) from the phosphorus-doped layer seems very similar to the N-related spectrum, however, with two main differences; the Q0 N-BE line was very weakly observed and the part of the spectrum showing the phonon replicas had very high intensity and was slightly shifted to low energy with a difference of only 0.4 to 0.5 meV from the N-BE phonon replica.
