This conformal property of ALD films has allowed the successful coating of powders,[4] nanoporous membranes and high aspect ratio trench structures.[5] ALD techniques exist for depositing a variety of substances including oxides, nitrides and metals.[6] ALD usually occurs at a lower temperature than chemical vapor deposition (CVD).[7] Zinc oxide (ZnO) films become widely used transparent conductive oxide (TCO) thin films in optoelectronic devices such as solar cells and displays because of its low cost and toxic free.[8-13] Although ZnO thin films possess low cost advantage, its electrical and optical properties are normally worse than those of indium tin oxide (ITO) films.[14,15] Therefore, how to deposit a high quality ZnO film becomes an important issue in the TCO applications.
Furthermore, ALD is based on the thermal process in which the surface chemistry is only driven by thermal energy delivered to the substrate.
In general, ALD is based on the thermal process in which the surface chemistry is only driven by thermal energy delivered to the substrate.

Owing to the diversity of source and microbial species, the constituent chemistry of LB-EPS is varied [5].
In the lake sediment, the chemistry of EPS, when separated by six different methods, showed that proteins, carbohydrates and humic acids accounted for most of the LB-EPS.
The regional positions of the EX/EM fluorescence peaks in samples from different origins, could be described as follows: Regions I, II, IV are aromatic proteins containing tyrosine, tryptophan and complexed tryptophan&protein-like compounds related to biological processes (EX = 210 nm - 280 nm, EM = 280 nm - 380 nm); Region III represents fulvic acid-like compounds (EX: 210 nm-250 nm, EM=380 nm-425 nm); Region V contains humic acid-like structures (EX: 250 nm-280 nm, EM: 380 nm-430 nm).

Introduction Zirconium diboride (ZrB2) has been widely used in high temperature structure ceramics, refractory materials, electrode materials due to its high melting point, high hardness, good heat and electrical conductivity and many other advantages [1-3].
In recent years, chemistry synthesis methods are widely used to prepare ZrSiO4 powder, such as solid phase method, hydrothermal method, precipitation method and sol-gel method [10-12].
