Later, we use powder as the sputtering source, adopt the method of reactive sputtering target doped powder to "sputter" and successfully produce (with SnO2-based materials) thin film gas sensors.
Using the powder sputtering method, we have produced in succession thin film gas sensors components with good performance by means of ZnO, Fe2O3 and TiO2-based materials.
Fig.1 Chip structure a) The gas sensing film is limited to the inter-digital electrode area using SnO2/x%CeO2 as materials.

Development and Comparative Analysis of Aluminosilicate Based Ceramic Filters for Ground Water Defluoridation Johnson Kwame Efavia*, Abu Yayaa, SolomonAdebornaa, Julius Fobilb aDepartment of Materials Science and Engineering, University of Ghana, Legon bDepartment of Biological, Environmental and Occupational Health Sciences School of Public Health University of Ghana, Legon *Corresponding Author: Materials Science and Engineering Department, University of Ghana, Legon, Accra-Ghana.
This worktherefore seeks to developcheap, efficient and sustainable porous ceramic bodies (filters) from alumino-silicates (Al oxides) based materials for the potential adsorption of fluoride ions from contaminated water bodies in the Bongo district of Ghana to levels accepted by WHO standards [13,14].
Materials &Methods Raw Materials and Preparation The porous media (filter) used for this investigation was based on aluminosilicates and includes Anfoega clay deposits in Anfoega- Volta region of Ghana, Kibi Kaolin deposits in Kibi- Eastern region of Ghana.
We then sized the ground samples using a sieve stack of:500µm, 355µm, 90µm and 63µm.Saw dust was used for the formation of pores in the aluminosilicates materials (Anfoega clay, Kibi Kaolin and Laterite as well as Termataria Earth).

Introduction The municipal solid waste contains materials which vary widely in size, moisture, and nutrient content, and organic fractions of solid waste can be mixed with varying degrees of non-compostable wastes and possibly hazardous constituents.
Methodology Municipal solid waste was collected from Faculty of Science and Technology for the composting process.

The rigid visco-plastic FEM is the main numerical simulation method in the metal bulk forming and its basic equation is based on the Euler coordinate system.The basic assumption of the rigid visco-plastic flow theory is[4,5]: ignoring the elastic deformation of the material and the quality stress and the inertia force; the materials in even quality and having the same character of their directions; the volume of the material not changing; the materials abiding by the Mises yield criterion and strengthening at the same direction; the rigid-plastic material changing only on strain hardening while the rigid visco-plastic changing on both the strain hardening and strain-rate hardening simultaneously.
