Abstract: The present invention relates to a multifunctional wood preservative composition containing a compound prepared by reaction of hydrazine hydrate and boric acid and to a method for wood preservation treatment using the same.
The wood preservative composition of the present invention can not only impart flame retardant, insect-repellent, rot-resistant, insect-repellent, and rust-proof effects to wood, such as various wooden structures including wooden cultural assets, but also causes no whitening and makes relatively fewer color changes for dancheong. Furthermore, the wood preservative composition of the present invention is provided as a one-component type liquid and thus can save time and costs for wood treatment and is convenient to use.

Abstract: A thin film deposition apparatus mounted with a Raman analysis system is discussed. The thin film deposition apparatus includes a reaction chamber providing an inner space for forming a thin film. An opening is formed on the thin film deposition apparatus to be connected to the reaction chamber, and the opening is closed by a window through which light can be transmitted.
