But it is difficult to obtain the VO2 structure of high purity by the RF magnetron sputtering.
Additionally, the multilayered structure has high visible light transmittance, which is almost irrelevant to the temperature.

Not only the pore structure, but also the surface chemistry composition of ACF significantly influences its adsorption capacities.
The HNO3 and H2O2 with different concentration were selected to investigate the influence of adsorption properties and surface chemistry composition of ACFs.
Materials and methods The ACF used in this study was from Shanxi Institute of Coal Chemistry (Taiyuan, China).

Mullite, according to its prismatic crystal structure and high content of aluminum oxide, increases the mechanical strength and thermal resistance of ceramics. [8] Cordierite and mullite in different temperature ranges: 1150-1300 °C and 1400-1600 °C are synthesized respectively [9], so combining them into a single composition represents some technical difficulties.
