* Key Technologies R&D Program of China(Project Number: 2006BAJ04A04-02)
Keywords: desulfurization hemihydrates gypsum (DHG); desulphurization fly ash (DFA); modified adobe materials; drying shrinkage; durability
Abstract: As a modifier, desulfurization waste can improve the performance of traditional adobe materials.
Currently, the modifiers of adobe materials are cement, lime,fly ash and other cementations materials [3,4].
Consequently, adding DFA into the adobe materials, the water resistance of adobe materials can be improved significantly.

Often used as protective coatings of gas turbine or engine components, nuclear materials and medical devices, many nanostructured materials are known to have several structural crystalline phases, according to the synthesis temperature and pressure, such as diamond and zirconium oxide.
Most nanostructured materials are obtained through gas-solid reactions, which are controlled both by kinetic and by thermodynamic factors.
Thermodynamic data for many oxides, nitrides, carbides and other high-temperature phases are currently available either in material science source (JANAF Tables, handbooks, etc) or rather specialized source (Thermocalc Database).
For a better understanding, and due to size restrictions, the paper focuses on diamond nanostructured materials.

Abstract.
The materials described in this article are widely used nickel alloy Inconel C-276 and super duplex steel SAF 2507 as clad materials for their superior resistance to corrosive environment and low alloy steel P355NH as a base material.
From the materials science point of view the interface is a complex system composed of intermetallic nanomaterials and amorphous compounds exhibiting often unique properties. 100 µm P355NH base material A SAF 2507 clad material Wavy joint with melted zones Melted zone B SAF 2507 clad material P355NH base material 20 µm ION etched melted zone C SAF 2507 clad material P355NH base material Wavy joint with melted zones D Inconel C-276 - clad material P355NH base material 100 µm E Inconel C-276 - clad material Melted zones P355NH base material 20 µm ION Etched melted zone F Figure 3.
The basic condition of obtaining the joint is forming the plastic zone in the collision area of welded materials.

Based on the shear strength of the pile-soil interface of different materials and the shear performance of the soil around the pile, a calculation equation for the standard value of the ultimate lateral friction resistance of concrete piles in different homogeneous soil materials was derived and applied to the equation for calculating the ultimate bearing capacity of foundation pile and the axial force of pile.
For example, Zhu [10] measured the internal friction angles of two kinds of sand gravel soil materials, D20 and D60, respectively, as 40.1° and 43.6°using a large one-way compression meter and an earth pressure box.

This collaboration between design and science opened up for a wider range of material design and functional possibilities, as well as more circular value chains for materials.
Although a wide array of methods for producing vegan leather exist in the textile and fashion field, combining the rigour of material science with design methodology could be more convincing in moving materials away from basic research and towards industrial applications to demonstrate their functional properties of materials.
