The application of these materials in tissue engineering can be advanced through modification of surfaces from hydrophobic to partially hydrophilic.
GP and GO, are the most fascinating materials based on their interaction with stem cells channelled cell attachment, cell proliferation and differentiation into various lineages like osteoblasts, chondroblasts, and neurons [11,12,17].

Cargoes which may liquefy (Group A) means the material that is made up of at least part of the mixture of particles and certain content of moisture, if moisture content exceeds a certain proportion, effected by outside forces in the process of maritime transport, the moisture will migrate and gradually form the liquid on the surface of goods then will make the cargo shifting.
The liquid refers to the material produces flow trend and possibility under the action of outside factors, it is the most significant and the main features of the cargoes which may liquefy.
Impurities should not be mixed in the loading process, especially the combustible material.

For example, the traditional software development method provisions writing detailed documentation material at each stage of development, such, development process is complicated, and a lot of times are consumed.
Because, the reusable software materials is reliable, therefore, in their base, the quality of the software system is reliable.

The technique can also be applied to other WBG material with a bandgap above ~2eV such as GaN, AlN, BN and diamond.
According to recent studies, this technique of capacitance determination can be extended to doping measurements on other wide bandgap material such as SiC including multilayer epi structures [6].
