Although 4D printing technologies still remain intractable, some aspects of improvement through electrospinning are possible in terms of responsive materials and self-growth materials.
Prospects of 4D Nanomaterials 4D materials contain the traditional 3 spatial dimensions and time which is the fourth dimension that affects the materials in some ways.
With respect to biomedical applications, 4D printed materials typically are divided into two types, one of which is responsive materials, and the other of which is self-growth.
Prospects of 4D nanomaterial are foreseeable in terms of its types of responsive materials and self-growth materials.

As a type of the novel semiconductor materials, tungsten oxide (WO3) is applied extensively in recent years for its electrochromic property.
It has been widely used in many different applications, such as electrochromic windows, optical devices, fuel cells, gas sensors, and photocatalyst materials, etc.
Experiments In the experiments of fabricating hydrogen sensitive films for the optic-fiber sensor, tungsten trioxide was used as the basic materials, and the platinum-doped WO3 films were prepared with sol-gel method and magnetron sputtering method, as shown in Figure 1.

Anthracite and lignite were taken as raw materials in those experiments.
Anthracite in Taixi Ningxia province and lignite in Rixile Neimenggu province were taken as raw materials.
Because the average particle size of raw materials had been chosen is below 10mm, usual intermediate grinding process can be passed.
Therefore methane adsorption ability is mainly decided by materials’ microporous.

Introduction According to statistics, the world annual consumption of iron and steel materials reached more than 700 million tons, of which 50% due to material wear and consumed.
According to our statistics of the five systems in metallurgy, mining, agricultural, coal, electric power and building materials, as well as the mechanical department vehicles, tractors, construction machinery incomplete statistics, estimates of China's annual consumption of metallic materials amounted to more than 3 million tons.
Therefore, how to improve the strength and toughness of the metal wear-resistant materials have been pursuing.
Experimental and Materials The chemical composition of the test cast steel.
