Polydopamine (PDA) materials also have attracted widely attentions since Messersmith etc. reported PDA material could firmly adhere to almost all surface of materials [14].
However, PDA materials, used to be filler to construct nanocomposite hydrogels, is still unexplored.

At present, biochar was mainly used as raw material for combustion or soil amendment [4].
The biochar, produced from fast pyrolysis of lauan in a fluidized bed reactor was used as the raw material.

Methodologies in the context of software engineering referred to “a codified set of recommended practices, sometimes accompanied by training materials, formal educational programs, worksheets, and diagramming tools.
Finally, "criteria and specifications" exist as a category of knowledge only in engineering and not in science.
In science, the aim is to understand: scientists do not need to have highly specified or concrete objectives.

Moreover, the tool's length involved in cutting is not constant in flank milling, which results in the changes of the material removal rate.
Then the velocity of points along the tool axis and the scanning area of the tool in unit time to describe the material removal rate of flank milling are deduced.
