In the mid-۱۹۸۰ Steven Slater (Steven C. Salter) member of the group was that the task it PBUH gene of the builder plastic from باکترى. Researchers ago than you feel that placing this enzyme in a plant can convert acetyl-coenzyme A (matter of zoning that during the conversion of sunlight into energy, it is natural in the plant formed should be) only plastic will do. In the year ۱۹۹۲ cooperation between scientists from the University of state of Michigan and the University of James Madison with this goal began. Researchers do engineering the genetics of the plant Arabidopsis Thalianan could [PHA crisp build. Two years later, the company Monsanto, for making the type more flexible PHA is a plant, the more usual meaning of corn began. Since the plastic production must be the production of food competition. researchers Your goal, it is to be used from episode one of the plant corn, which are harvested not to be found (like leaves and stems) was made. The growth of the plastic in the leaves and stems to farmers, yet the possibility cannot offer that can be combine of the question, and the fruit of the corn harvest, and with زیرورو re-farm the leaves and stems that contain plastic picked. Unlike the production of PHA and PLA to the method of fermentation, which should use the land for corn production for other purposes of competition. the growth of the PHA in the leaves and stems of corn, the possibility to the existence of God that can be corn and plastic simultaneously from a farm acquired. By the way, with the use of appropriate plants adverse conditions, like Switch grass can be from the confrontation between plastic production and other uses of land loss. What don't you see, that's just the ground that for the cultivation of corn to make this work assign. Researchers to the advancement of his sky in the field of increasing the amount of plastic in the plant and also changed the chain, and plastic in order to produce useful properties, etc. have been achieved. Although these results, when independently accessed, which are encouraging have the obtainable to both, concerning this, combining the useful and also the amount above the plastic in your plant is a problem. So far, it has been demonstrated that the chloroplasts of leaves is the best place for the production of plastics. But the chloroplasts are members of him, are that the task of their absorption of light, and this is in order that the concentration above the plastic of the photosynthesis loss and بازدهى plant to reduce him. Also, PBUH Plastic of the plant is a challenge. They researchers company Monsanto facility extraction as unit, quarter, factory, فرآورى corn in a comment). But when this unit's the paper, and the house they noticed were extracted, and the third type of plastic to the values of the transformation in a solvent requires that the result he had later in order to re-use بازیابى. This infrastructure process, in terms of size, the factory, the existing پتروشیمیایى manner), and the size of the factory Asia corn greatly increased God. It should be noted that the Do capital based and the passage of time causes that researchers on these obstacles, which overcome.

Early humans with the use of natural polymers, tool life, and the weapon name. But in the late nineteenth century was that humans could change the shape of the polymer managed to build پلاستیکها. Cellulose in the natural state, non-melting and in solvents, normal non-solvable. With نیترودار it is the first plastic business trade name Nitro cellulose emerged that significant dissolution and شکلپذیر.
In 1870, etc. of plastic called celluloid was marketed through which soften the nitrocellulose with camphor was achieved. This substance is a transparent, stiff and قالبپذیر in the preparation of objects such as artificial brush and comb, etc., fibers, etc., lacquer and ... application.

Studs storage, in fact, given the level of wooden objects so similar to the mosaic with the small arrows, and this is مثلثها whatever more elegant and designs, and the problem is that with this triangle arise whatever the regular would be more studs مرغوبتر. Of course, the quality of the raw materials used in the studs also causes the raising of the value of it.
