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).

Experiment results show the dependence of the abrasive particles on the choice of materials.
Mechanical machining methods are not suitable for machining of workpiece materials for modern optical system.
Different combinations of workpiece materials and abrasive with different machining processes shows complete reverse material removal rates.
Experiment results indicate the dependence of the abrasive particles on the choice of materials.

For materials and design, it is the blending of arts’ elements and science that make it work [10].
Most of the buildings in Fig. 4 were devised before the science of stress analysis had developed, but even without it, the designer was capable of visualizing the forces and the relationship between the forces, materials, and form.

Li et al. [20] used the flotation method to deal with the iron tailing from Anshan iron and steel corporation, the procedure was proved to be with significant economic benefits. 2.2 Construction materials from iron tailings General particle size of the iron tailings in China is less than 0.074mm, the proportion is about 75%, meanwhile, the chemical composition of iron tailings is close to that of ceramic materials, glass and tiles, which makes it possible to prepare construction materials from iron tailings. 2.2.1 Paving materials Paving materials is the most basic building materials, without strict chemical requirement but some certain hardness and grain size.
These enterprises use their own separation process and the local resources to produce paving materials and have obtained certain economic benefits [21]. 2.2.2 Wall materials For a long time, the clinker brick is the main wall materials of our country, however, the production of clinker brick will occupy a large scale of farmland, which is not advocated now, as a replaced material with an increasing amount each year, the iron tailing is mainly studied by different enterprises for the possibility to be used as raw materials for wall materials, which is also considered to be the main method for the reutilization of iron tailings [22].

With the development of science and technology, before the ever-changing professional knowledge, it is difficult for him to find right novelty points.
For example, some confidential documents aren’t included in digital datasheet, such as glossary of materials, communications with experts, study bulletin and so on, which couldn’t be neglected in the novelty search.
And there have been some scholarly journals to be largely introduced from all kinds of specialty associations in the west..
