Introduction Among various oxide semiconductor, Ti-based materials is the most promising and challenging investigated materials because of its characteristics of high chemical stability, nontoxic, low cost and unique photoinduced electron transfer.
The use of Ti-based photocatalyst materials such as energy sources [1,2], environment [3,4], biological sciences [5], medicine [6] and manufacture [7] is an attractive alternative.
Many different preparation methods have been reported for preparing Ti-based photocatalyst materials.

Introduction In the response study of underground structures due to blast over a long distance under elastic range, stiffness of the constituent materials is the governing factor.
The two elastic constant are enough to study the behaviour of such materials [2].
Soil-pipe interaction due to blast depends mainly on stiffness of materials of the components.
This situation may be overcome by using softer material like tire-chip for backfilling.

The Hydrothermal Synthesis of Nano-YSZ Crystallite and the Preparation of YSZ Electrolyte Film for SOFC Baoan Fan1,a 1Hubei Provincial Key Laboratory of Coal Conversion and New Carbon Materials; College of Chemical Engineering and Technology, Wuhan University of Science and Technology, Wuhan 430081, P.
Traditionally, the SOFC operational temperature is as high as 1000 °C, which makes SOFC must use expensive LaCrO3 connector and ceramic seal materials.
The traditional materials of electrolyte and anode are YSZ (ZrO2 stabilized by Y2O3) and NiO/YSZ composite respectively.
