During the last several decades, many materials have been examined with respect to their use in display devices, energy efficient smart windows, large-area applications in electrochromics, automotive mirror and sunglass products [1,2].
Transition metal oxides have been widely used as inorganic electrochromic materials.

Methods and Materials Materials and Apparatus.
All plant materials were collected from the dominant plants on lead-zinc tailings of Huize, and tailings soil were collected from lead-zinc tailings (the old tailings have been accumulated for 12 years and new tailings have been accumulated for 5 years), tailings soils were dried naturally and crushed for experiments.

Furthermore, a better improvement for the hydrophobic stability of cotton filter cloth significantly enhanced the application of hydrophobic functional modified cellulosic materials.
Introduction The hydrophobic modification of cellulose by electron transfer (ARGET) atom transfer radical polymerization (ATRP) is a new method in the field of functionally modified cellulose materials [1-5].
The relevant progress on hydrophobic modified cellulose materials by ARGET-ATRP method was less reported till now.

At present, the materials with highest TE performance are intermetallic compounds such as Bi2Te3 [7–9].
The known material of NaCo2O4 was recently discovered to be good TE material [10,11] to encourage researchers for exploring new TE materials in metal oxides.
Thus, some 3d transition-metal oxides are candidates for new thermoelectric materials.
Thus, vanadium oxides are good candidates of highly efficient TE materials.

The level of density also relates to the space between molecular materials.
There are two sizes of materials, 1 and 3 cm.
At the F/S ratio of 0.025, 1 cm gave 1.40% yield, and 3 cm size materials produced 1.25% yield.
Power of 2100 W gave the highest yield for both 1 and 3 cm sized materials.
