In addition, in contrast to most materials expand upon heating due to positive coefficient of thermal expansion (CTE) [24-28], graphene can have a negative CTE owing to out-of-plane thermal fluctuations [29,30].
Intensive research showed that the addition of graphene can significantly reduce the CTE of organic materials [31-33].

Introduction Light metal aluminum has become more and more important raw materials in people’s daily life, and the production and processing of aluminum can be seen everywhere, so it is necessary to understand and have a good master of the basic properties of aluminum.
Another example is Peilan Wang et al[2], they comparatively studied the law of ignition delay time, dust granularity and dust concentration impacting on TNT dust, RDX dust and flour, and discussed qualitatively the explosive process of energetic materials and general dust (an external oxygen supply).
Only when the combustible materials burn out, the explosive pressure and the flame propagation speed will reduce and decrease slowly, and then tend to level off, and finally return back to the normal status.

The purpose of this study is to evaluate either it is feasible to create an MDF that complies with the current standard using young rubberwood in order to compensate the current shortage of raw materials in MDF industries.
Materials and Methods The planting location for this clone series of rubber tree is determined, at latitude N5o and longitude E112oE which has average of rain is about 4000 mm a year.
The amount of fibre and the amount E1-grade urea formaldehyde resin for each board were calculated based on the oven dry weight of the fibre materials.
MOR is used to determine the suitability of material for structural applications.
