Their greatest advantage is their mobility, low weight, relatively high performances and quality processing materials.
The used technology of cutting and processing wood and wood-based materials as well as the used tool also, to a great degree, take part in production of dust particles.
From the viewpoint of primary dustiness, the proportion of the particles with the dimension ≤ 80 μm in diameter is very high as for all types of sanders and sanded materials.

Finally, the materials themselves are much less expensive than silicon and because the sheets are so thin, they require only minuscule amounts of the materials to further bring down overall costs.
An additional advantage of these materials 2D is their long-term stability , even in open air; other solar-cell materials must be protected under heavy and expensive layers of glass.
Grossman explained that these types of materials are essentially stable in air, under ultraviolet light, and in moisture.
The research on graphene is only the tip of the iceberg in terms of utilizing 2-D materials for clean energy.

The rapid development of biology has led to the widespread use of completely new practical methods to solve healthcare problems, as well as to the fundamental development of new technologies and new materials in various industries [15, 17, 21, 22, 23, 25].
Meanwhile, the problem of unpredictable effect on the environment of materials, created and modified using nanotechnology, does not allow us to consider current ethical approaches as sufficient.
As using nanotechnology, it is possible not only to modify existing natural materials, but also create new materials with desired properties, they are seen as a source of conscious design of both risks and desirable properties of nature.

Composite materials or generally materials with interfaces are nowadays used in many varied engineering applications.
The considered thickness of both materials (1 and 2) was the same, i.e. t = 15 mm.
This effect can influence time to failure of structures made from materials with interfaces (e.g. composite materials).

Hence, the use of alkali treated bamboo particles as reinforcement was a feasible and competitive method of creating new materials.
Experimental Methods Materials Sawdust of bamboo was collected from bamboo processing factory, Lin'an, Zhejiang Province and ground to 200-400µm with a hammer mill [12].

The concomitant tag will store the information that greatly help user in sorting the materials.
However, for the sand and rock situations, the success rate is almost the same with 500ml case since the small volume of such materials will make it hard for the system to read the dielectric strength of each items.
