So nanoscale materials and devices will play a major role in intelligent communication system.
Such materials and devices would certainly leverage the future direction of research in wireless communication systems.
The materials used in such devices should be robust, easy to use and easily deployable [3].
Nanometer-length scale materials play a vital role in the manufacturing and controlling of novel and innovative devices.

Optimization of extractive condition of Zanthoxylum alatum seed Oil Zhang Lei1, a, Chang Min2 , Su Ming2 and Niu Sheng-yang1 1School of Food Science,Henan Institute of Science and Technology,Xinxiang,Henan,China 2School of Economics and Management,Henan Institute of Science and Technology,Xinxiang,Henan,China azhanglei7801@163.com Keywords: Zanthoxylum alatum;Zanthoxylum alatum seed oil;Extractive condition;Orthogonal experiment Abstract.
In this paper, Zanthoxylum alatum seed oil is extracted by solvent leaching formulation, and by single factor and orthogonal experiment analysis, to determine the optimum technological condition of the extraction for Zanthoxylum alatum seed oil. 2.Materials and methods 2.1 Materials Zanthoxylum alatum seed: picking prickly ash of the current year, remove shells. 2.2 Pretreatment of the raw material Choose clean and not cracking of Zanthoxylum alatum seed, first for drying, and then smash processing. 40 mesh screen smash was used in the test. 2.3 Optimization of Zanthoxylum alatum seed oil extraction methods This trial is tested by dipping extraction method for extracting, in order to determine the best extraction process conditions.
At 85℃ extraction ratio has declined, the reason is anhydrous alcohol as extractant, most extraction of prickly ash oil is low boiling point material, temperature’s rising can cause certain heat-sensitive material decomposition which in prickly ash oil.
Extraction of prickly ash seed oil and its utilization: submitted to Journal of Chinese oil (2006) [2] Zhuang Shihong, Li Menglou.
