The carbon source is found in a variety of materials, such as peanut shells [1], coconut husks [2], or physic nut [3].
The major components of raw materials are volatile matter and fixed carbon.
With the increase of impregnation ratio, the reaction rate between the activator of NaOH and carbonized materials becomes faster.

An estimation method to predict creep performances of high temperature structural materials has been proposed.
The technique invokes high costs in term of energy, manpower, and materials and is inefficient.
This is a major obstacle to the development of new or improved materials.

The adaptive meshless model takes into account the temperature variation, micro plastic flow, and the coupled thermo-elasto-plastic behavior of the materials, considering the strain-hardening property of the materials and temperature-dependent yield strength.
Depending on load, sliding speed, friction coefficient and contact geometry, one may obtain sufficiently high asperity flash temperatures to cause thermal softening of materials [2] in contact.
The material properties including the modulus of elasticity E, the yield strength σY , the coefficient of thermal expansion θ, the thermal conductivity k and the Possion's ratio v are sensitive to temperature changes as well, especially the yield strength σY is sharply decreases with temperature rise for many engineering materials [3].
