Very generally material science could be divided into two groups: scientists who try to invent new materials or improve existing ones and those who work on finding the best applications for the modern materials.
Among them there is group named “smart materials” or “active materials”, which have ability to change theirs properties according to the external stimulation.
It assumes usage of two identical pieces of MSMA materials and energize them oppositely.
The article presents several applications of smart materials in valve designs.
Among the known solutions with materials piezoceramics, giant magnetostrictive materials and thermal shape memory alloys there appeared also ones with magnetic shape memory alloys.

The hardness of the obtained materials decreased, probably due to some loosening of the structure of the polymer matrix.

It is found that the DMFC performance of the membranes modified by two kinds of catalytic materials are better than that of the bare Nafion when operated with 2.0 M methanol.
In this research, two kinds of catalytic materials, platinum and palladium are used to modify Nafion.
In order to increase the compatibility between the Pt(Pd) and polymer, some organic materials are needed to bind well with both Nafion and Pt(Pd).

Anti-percolation of concrete materials is a very important technical indicator.
The anti-percolation of polymer materials increases with the increase of the density.

Nowadays, the inventory control is inclined to adopt different policies to different materials [1].
In the aircraft manufacturing industry, many materials can only be procured from one company and some materials are imported abroad, so it is more common that material can not be procured easily.
The Civil aircraft is manufactured in single-piece, so some materials are used only in one aircraft.

Introduction Wood Plastic Composite (in short WPC) presents a group of material emerging from a fusion of two different homogeneous materials – wood (hydrophilic component – wood flour obtained from maple, oak or pine.
Since then the market with WPC materials has grown into the many manufacturing spheres within the USA, Europe and Asia.
This article contains some results of the dissertation thesis entitled Contribution to a problem solution of machining of composite materials that are WPC based.

Therefore, to improve the toughness and strength of ceramic materials has been an important direction in materials science.
For ceramic materials used at room temperature, metal materials with better strength and toughness can be given as “exoskeleton” of ceramic.
For ceramic materials using at room temperature, toughen to the materials itself can be ignored.
Compared to metal materials, the composite materials reduce weight significantly.
