BulkGibbs free energy of formation of the amorphous oxide islarger than that of the corresponding crystalline oxide.
Thin filmThe thin amorphous metal-oxide film on its metal substrate can be stable modification with respect to the corresponding crystalline metal-oxide film the same substrate.

이와 같은 문제점들을 개선하기 위해 우리는, PMMA자체의 성질을 개선할 수 있는 작용기를 바꾸거나, 다른 고분자 물질과의 공중합체를 형성, 또는 표면에 다른 물질들을 코팅하는 등의 여러가지 방법들을 생각해보고, PMMA 이외의 물질 중 생체적합성이 우수하
chain. These basic structural properties play a major role in determining bulk physical properties of the polymer, which describe how the polymer behaves as a continuous macroscopic material. Chemical properties, at the nano-scale, describe how the chains interact through various physical forces. At the macro-scale, they describe how the bulk polymer interacts with other chemicals and solvents.
1. Monolayer of molecules formed by self-assembly ie., the structures are formed
without external intervention.
2. The structure is organized by utilizing weak interactions such as
H-bonding, van der Waals interactions and there are numerous
interactions of this kind in a structure which make it stable.
3. Nature uses the same process of self-assembly to produce comple
