The photocatalyst material and structure are the most important factors in the photocatalysis process.
The semiconductors such as TiO2, SnO2, and ZnO, are widely used in the photocatalysis field because of their availability, low cost, low hazard, and effectiveness, which can be improved greatly by producing these materials at the nanoscale [7-10].

Quantification of the ferrite grain size refinement promoted by vanadium enhancing allotriomorphic nucleation (grain boundary, g.b.) and intragranular nucleation (intra) Conclusions - The addition of small quantities of vanadium to low carbon structural steels produce a refinement in the final ferrite microstructure compared to the plain carbon material.

Nanotechnology can be defined as science related to tiny matters with the size of 1-100 nm.
The properties of nanotechnology are different from the original material and can manipulate data on an atomic scale [3].
The magnetic sensitivity of MnFe2O4 nanoparticle is higher than other ferrite materials such as Fe2O4, CoFe2O4, and NiFe2O4.

By such procedure it is possible to select the most power effective materials, designs and products and buildings as a whole [6].
Also considers that the solution of these problems will be possible only after creation of applied science on providing  qualities of air in the room and to risk management.
Dependence of the cost of one square meter of the substructure and the insulation material and energy costs on the thickness of the insulation.
The received results allow to draw the following conclusions: · It is shown that the cost of a substructure of systems of hinged facades with an air ventilated gap depends on heater thickness, besides, need for use of additional quantity of elements of a substructure and the consumption of materials increases with increase in thickness

This incentive act included 5 categories: 1. coordination with nearby dwellers including building colors, material, shapes and location; and building design as well. 2.
In addition, the analysis of how reshaping a cityscape by applying the new architectural engineering may affect economy, environment, and society can be further researched. 6 Acknowledgement The authors would like to thank many officers in the TCG for their help in putting together the materials concerning current statistics for the ‘Taipei Beautiful’ urban regeneration strategy.

LFRSC has several advantages, (i) it is useful for medium-temperature (70 - 200oC) range applications (ii) it is fabricated with narrow flat reflectors and constituent materials for its fabrication as well as replacement which are readily available in the market; (iii) the planar configuration and the air gap between the adjacent reflectors result in very small wind loading on the concentrator.
The maximum allowable material stress, (AS) is 68MPa for 320 Grades steel.
