The crystal structure, particle size and morphology can easily be controlled by changing the hydrothermal reaction conditions (such as temperature, pH, solvent composition, reactant concentration, additive, etc.).

Mainly due to a higher proportion of free CaO and due to the disordered structure of fly ash coming from fluidized low temperature combustion.

Higher resolution back reflection SWBXT images (Fig. 1b-c) reveal the detailed structure of the defects.

Preparation of Flower-like Silica Microstructures Wenqi Wang1, 2,a , Zhensheng Peng1,2 1 Department of Chemistry & Life Science, Anhui Key Laboratory of Spin Electron and Nanomaterials 2 Suzhou University, SuZhou 234000, P.
The morphology and structure of flower-like silica microstructures have been characterized in further detail using TEM and selected area electron diffraction (SAED).

Processing and Characterization of Ultra-high Temperature Oxide Fiber-Reinforced Oxide Ceramic Matrix Composites with Improved Thermomechanical Properties Cengiz Kaya1,a and Figen Kaya2 1 Yildiz Technical University, Faculty of Chemistry and Metallurgy, Department of Metallurgical and Materials Engineering, Davutpasa Campus, Esenler, Istanbul, Turkey 2 Zonguldak Karaelmas University, Engineering Faculty, Department of Metallurgical Engineering, Zonguldak, Turkey a cengizk@yildiz.edu.tr Keywords: Alumina; Mullite fibres; Interphase; Electrophoretic deposition Abstract.
Higher strength values obtained from NdPO4 interface was contributed to the dense structure of the coating layer so that the reinforcement mullite fibres were protected from severe oxidation at high temperature although it is not well understood from the Fig.4c that sample with ZrO2 interface lost higher value in strength compared to NdPO4.

Synthesis of Eu(TTA)3phen·H2O-PVP Composite Film and Study of Their Luminescence Properties Qing Liua, Zhenxing Yaob, Xianpeng Zhengc, Yanming Yangd, Qin Weie, Bin Du*f 1 School of Chemistry and Chemical Engineering, Univerity of Jinan, Jinan 250022, China a liuqingcq@163.com, blaoqq007@sina.com, czhengxianpeng1984@163.com, d yangchen0124@163.com, esdjndxwq@163.com, fsdjndxdb@163.com Keywords: Europium(Eu); Rare earth complexes; Polyvinylpyrrolidone(PVP); Luminescence film; Concentration quenching.
Introduction Rare earth complexes have particular properties of light, electricity and magnetism due to the special electronic structure and bonding characteristic of lanthanide ions [1-5].

It is very desirable to establish a connection between technological modes of operation at production of tools, their structure and phase content (on the one hand), and operational characteristics (on the other hand).
