3. Results and Discussion
3.1 Morphologies and structure(SEM)
Fig. 1 (a)shows SEM image of as-obtained ZnO nanowires of in the first step ranging from 80 to 400 nm in diameters and about 4 mm in length. Gold particles at the tips of the nanowires can be seen in Fig. 1(a). This indicates that the ZnO nanowire growth was governed by a VLS process. Fig. 1(a) shows ZnO nanowires obtained under th
Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
and the airports themselves are to be effective in countering security threats, there must be a clearly established process that starts with the issue of policy at national level and is operationally apparent in the procedures adopted by the individual airports. National policy is translated into a national security plan or overall security program, a necessity if airports and government wish to
