Morphology investigation using TEM found out small diameter of nanotubes structure within 8 –
10 nm of pure and F doped TiO2 nanotubes.
Figure 1: XRD patterns of (a) TiO2 nanotubes and (b) F doped TiO2 nanotubes As shown in Fig. 2, the TEM micrographs indicated that the TiO2 nanotubes (Fig. 2(a)) and F doped TiO2 nanotubes (Fig. 2(b)) samples had predominantly nanotubes attributed to the hollow elongated structures was observed.
This is probably due to the quantum size effect of TiO2 semiconductor in nanotubes structure [12].
The nanotubes morphology and anatase phase structure of synthesized F doped TiO2 nanotubes was found to be similar to pure TiO2 nanotubes.

The morphology and the structure of sol-gel films under study were
characterized with SEM/EDS techniques.
A significant advantage is that irregular shapes and larger integral structures can also be coated.
The structure of the films was characterized by Scanning Electron Microscopy (SEM).
Scanning Electron Microscopy (SEM/EDS) was employed to study the structure and composition of hybrid films.

This paper reviews the recent work [11-13] carried out in the Department of Solid State Chemistry of the AGH University of Science and Technology in Krakow, Poland on the high-temperature resistant and protective films with regard to their application as interconnect coating for SOFC’s.
It is very likely that the existence of the intermediate layer with a complex multilayer structure, which relaxes the thermal strain at the steel/film interface, improves scale adhesion

Because of the stable chemical structure, nitrobenzene shows a lack of auto oxidation or any oxidative degradation via hydroxylation.
Presently, a lot of researches about the removal of nitrobenzene in water by biological or physical chemistry methods were reported, but the report about the remediation of nitrobenzene-contaminated soil was very few.

Environmental Protection and Fuel Consumption Reduction by Flameless Combustion Technology: A Review

Fundamentally, flameless combustion is identified by aspects of turbulence and chemistry strongly [10].
The impacts of recycled flue gases under highly preheated air conditions (from1200to 1600 K) were investigated by Katsuki and Hesegawa [16] wherethey found that the flameless combustiongenerates by high velocity of reaction air.Dally et al. [17] stipulated that the flame structure starts to change when the level of oxygen decreases and it happens at high Reynolds number for air jet and low oxygen concentration.The peaks of temperature are located in the center of the furnace at the burner level, far away from the burner position [18].
Mechanism and stabilization of nitrogen chemistry in combustion.

For these reasons, various HA synthesis techniques have been developed which are mechanochemical synthesis, combustion preparation, and various techniques of wet chemistry, such as direct precipitation from aqueous solution, electrochemical deposition, sol-gel procedure, and emulsion or micro-emulsion route, etc. [7-9].
The pH value of the starting reaction solution is the most significant variables in altering the HA structure and morphology.
