Animated nature has the most complex materials, devices and processes in comparison with all the inventions of mankind.
Natural materials are very cheap and abundant, their "quality" is much better than those made by man.
Modern biomimetics is largely associated with the development of new materials that copy natural ones.

Although the critical aspects of hazardous and toxic materials within oily petroleum sludge had been widely addressed, very little attention had been given to NORM and TENORM in such sludge.
As for recyclability, it promotes extracting and recycling the available materials from the sludge matrix to be used as an alternative energy source.

Efforts have been made to synthesize mixed-metal cathode materials such as LiNi1/3Co1/3Mn1/3O2 based materials with promising electrochemical characteristics.
This is to lower the expensive Co content and help to stabilize the materials.
The cathode materials were then fabricated for electrochemical analysis.
The materials annealed at 900 oC for 24 h show best performance over the other materials.

Experimental procedure 1.1 Starting materials The starting materials include nature silica, industrial alumina, carbon black, coke and anthracite.

Due to their physical and chemical advantages when compared to classical industrial materials, composites are candidate materials of the future.
Composite materials are engineered materials made from the macroscopic combination of two or more different constituent materials under certain conditions and proportions that, individually, do not achieve the desired aim.
