This definition is broadly in accordance with the definition that Bell proposed for ''duplex surface engineering''.
Hybrid processes can be very easy to handle and very efficient to grow nanostructured materials.
Conclusion The complexity of the materials deposited by hybrid processes can be regarded as an advantage since we wish to create new materials with original structures and properties.
Then, we are far from being able to describe thoroughly these processes despite materials with new properties can be grown in thin film.

These materials possess good optical properties, unique mixed electronic and/or ionic transport properties and high conductivity/weight ratio.
Among them, the most promising materials include the polythiophene derivative PEDOT (poly(3,4-ethylenedioxythiophene)), especially its form in combination with poly(styrenesulfonate) (PSS).
In a several publications, photochemical approach was used to conjugate RGD peptide to different materials [21]–[25].
Materials and Methods Sample Preparation.
The improved hydrophilicity of the surface of different materials after RGD modification was already published in several papers [28]–[30].

Nonprecious metallic alloys, including stainless steel (316L), Co-Cr based alloys, Ti-based alloys are the common materials used to manufacture the PFM dental restoration owing to the economic cost compared to the noble metals such as gold, silver, and platinum.
Since the PFM is considered as the composite materials composed of metal and porcelain (ceramic) phases, the bonding strength between two different phases is the important key in determining the reliability of this device.
Henriques et al. [4] suggested that oxide formed on the based metal surface could effectively improve the bonding strength between metallic frame and porcelain whereas the excessive formation of oxide lowered the bond strength of these dissimilar materials.

The research from International Data Corporation (IDC) shows that the data amount that the global produced in 2009 is 0.8ZB,and it increased to 1.2 ZB in 2010, what’s more, it reached up to 1.82 ZB in 2011, but by 2012, the data amounts of all printed material humans generated was only 200PB.
The Obama administration also announced "big data research and development plan" in March 2012, and declared that it would invest 200 million dollars pulling the industrial development related to big data, aimed at improving the capacity of the people to get knowledge from the huge amounts of data available, thus accelerating the United States’ pace of invention in science and engineering to strengthen national security.
It achieves the traffic management become a "points to points, key to key, zero distance, and unclocked" service.

As one of the key technologies of UAVs, path planning has attracted extensive attention from scholars all around the world.
Path Coordination Approaches The key to solve cooperative path planning problem is how to deal with coordinated relationship among tracks of different UAVs.
Potential energy function is constructed with material diffusion equation in physics, and then the fastest rising curve from the beginning to the end is the path to be found.

Desulfurization of Simulated Coking Benzene on Modified Activated Clay Chunguang Pan, Hongzhu Ma* Institute of Energy Chemistry, School of Chemistry and Chemical Engineering, Shaanxi Normal University, Xi'an, China, 710062 E-mail address: hzmachem@snnu.edu.cn (H.
An effective catalyst is the key of alkylation transfer desulfurization, and the activity of acidic catalyst in the alkylation reaction mainly depends on its strength of superacidity [11].
The activated clay, which is quite abundant in the earth’s upper crust, is an important and cheap raw material for manufacturing such as adsorbents [15] and catalysts[16].
So the key step for improving the catalytic activity was enhanced the acidity of the activated clay.

Ethylene-propylene rubbers are becoming more widespread in the rubber industry due to the availability of raw materials for synthesis, a high range of technical properties and a relatively low cost of rubbers based on it due to the ability to take a large number of fillers and softeners [1-3].
As a rule, the best complex of properties is possessed by vulcanizates containing crosslinks of different thermal stability (for example, a combination of carbon-carbon and monosulfide with polysulfide or ionic ones) and statistically (evenly) distributed over the volume of the material.
In this work, in order to expand the temperature modes of operation by increasing the thermal stability of elastomeric materials, fillers were used in the composition of elastomeric compositions, which change their structure under external influences [4].
Results and Discussion EPDM is one of the most widely used special purpose elastomers found in the production of single layer roofing materials, machine parts, wire and cable insulation and many other fields.
