The Synthesis and Structure of Anodized Titania Nanotubes for Energy Conversion Materials Rinnatha Vongwatthaporna,Narongsak Kodtharinb and Udom Tipparach*c Department of Physics, Faculty of Science, Ubon Ratchathani University, Warinchamrab, Ubon Ratchathani, 34190 THAILAND aemail: som_o_phys@hotmail.com, bemail: na.phy@hotmail.com, *cemail: udomt@hotmail.com Keywords: Titania nanotubes, TiO2, anodization, synthesis, nanomaterials, renewable energy.
Since then, a large number of semiconductor materials have been employed for photoanodes, also called working anodes for hydrogen production.
All of semiconductor materials, TiO2 and modified structure TiO2 are widely used because they are highly photocatalytic, stable, abundant, and environmentally safe [2].
These nanotubes can be used for energy conversion materials such as solar cells and hydrogen production cells.

Equivalent strain distribution Due to the large size and complicated structure of research object, materials can only fill the die cavity under stronger forces.
In the filling stage when the die core shoulder touches the blank materials, blank materials are driven by external forces to fill the die cavity gradually, reducing the free surface and increasing metal flow resistance accordingly.
In the final stage, the workpiece flange and upper and bottom corners are all filled with blank materials.

Introduction The development of damping materials and methods of their processing are of scientific and practical interest, as reducing harmful vibrations and noise from dynamically loaded items is a relevant issue nowadays.
Secondly, the improvement of the damping properties of magnetomechanical iron-based alloys, which have the highest damping capacity among the metallic materials known, is of great importance in dealing with harmful noise and vibration.
Materials, Treatment Methods, Investigation Techniques The research materials are Fe alloys, the main mechanism of internal friction of which is of the magnetomechanical nature: carbon-free alloys Fe–8%Cr, Fe–16%Cr, Fe–19%Cr, Fe–4%Cr–2%V, Fe–3%Cr–3%Al, as well as graphitic steel Fe–1,2%C–2%Si–2%Al.
