Jc cakes obtained after oil pressed, rich in protein content, were excellent materials for preparing formaldehyde-free wood adhesives, which could provide alternative to formaldehyde-based resins.
In addition, formaldehyde-based adhesives are derived from nonrenewable fossil resources, which generate an urgent need for the development of environmentally friendly alternative wood adhesives from renewable materials [2-3].

In a typical experiment, 100~800 cycles of ALD were performed to synthesize TiO2 and ZrO2 nanotubular materials.
The nanotubes of various materials can be fabricated by selecting the ALD precursors.
Materials of nanotubes were controlled with ALD precursors.
