In accordance with waste management measures set by the US Environmental Protection Agency (USEPA) in the 1970s, a robust cleaner production approach was proposed in the 1980s to develop an encompassing strategy which focuses more on waste minimization, pollution control, and recycling of materials [26, 27].
As industrial production processes increase in the area of energy generation and conversion of raw materials, considerable efforts must be put in place to eliminate poisonous raw materials and reduce the level of pollutant emissions which are bound to leave the processes.
Microbes like bacteria, yeasts and microalgae are known to have the ability of stockpile lipids and oils originating from these microbes are promising raw materials for biodiesel production [33 – 39].

The results showed that osteoblastic cells were able to adhere and proliferate on the HAp microspheres, which are intended to be used as injectable support-materials for bone regeneration.
Microparticles, suspended on appropriate vehicles, are among the most common forms of injectable materials.
Materials and Methods HAp microspheres were prepared as previously described [2,3].
Further studies to evaluate the influence of these materials on the expression of the osteoblastic phenotype are in progress.

Yellow River 2nd Bridge uses the adhesive materials of waterproof coating, so this article mainly introduces the construction technology of this type of bond coat [1].
Before the approach of the materials and the equipments, it needs to send constructers to inspect and clean the bridge deck, for ensuring that the base is flat, sturdy and clean.
In addition, it should make the exertion part of vent tube brush by the materials, as while as the inside of the vent tube which 10cm away from the deck.
d) The materials for waterproof must meet the quality indicators and the requirements of design. 2.

The effect of the particles' morphology on the deformation behaviour of the particle composite materials was numerically investigated [3].
Figure 1 shows an example of the microstructure of the composite materials W/Cu-80/20 and W/Cu 60/40 with an average tungsten particle size of 30µm.
Figure 2 shows exemplarily the flow curves of the investigated composite materials with a particle size of 10 and 30µm at 20°C, 400°C and 800°C and at a strain rate of 1 0.1 sε − =& (Figure 2).
The investigated W/Cu composite materials showed different size effects on the flow stress with varying the specimen size, where the stress level increases with decreasing specimen size.

Introduction The nodular cast iron, which have superior mechanical properties, quickly developed into one of the widely used cast iron materials in the last decade [1].
Experimental procedure Iron coated nodularizer production process This new process consists of the choice of clad materials, the design of gating system and selection of pouring temperature.
Attention should be paid to the clad materials, which must cannot contain anti-spheroidizing elements and react with nodularizer, have higher melting point than nodularizer, average density of coating materials and nodularizer is lower than nodularizer, but higher than liquid iron.
