Engineering - Essay Example MD simulations are performed to provide a comparison base for the results of the experiment in order to identify with the fundamental mechanism. The result of this shows to have defect formation depending on nuclear collisions up to attainment of threshold of ~ 2.2 keV/nm by Se over which the electronic energy loss becomes significance. The results from the experiment are given in terms of tables and figures. Figure 1 exhibited a distinctive Raman spectrum evolution of ID/IG in SiO2-supported graphene, in which 1 Mev C ions were applied. Table 1 constitutes a list of experimental results of estimated fault yields. There is calculation involving application of SRIM, the electronic stopping power, Se and the nuclear stopping power Sn of occurrence ion in SiO2 and graphene. Figure 2 involves a plotting graph on fault yields in graphene against irradiated ion in graphene nuclear stopping power. The conclusion shows threshold to be set by SiO2 substrate and also the defects of small size are formed in the graphene that is supported (Wang et al. 2015). Yeom, D. Y., Jeon, W., Tu, N. D. K., Yeo, S. Y., Lee, S. S., Sung, B. J., ... & Kim, H. (2015). High- concentration boron doping of graphene nanoplatelets by simple thermal annealing and their supercapacitive properties. Scientific reports, 5. The article is all about the study which involves demonstration of B-doped graphene nanoplatelets which can be developed by simple thermal annealing of GO nanoplatelets in boron oxide combination. This article begins by an abstract, which introduces us to graphene and its properties that enhance the carrying out of the experiment. Boron-doped graphene is introduced to be having electrical properties that are easily influenced by oxygen and water impurities. The next part is the introduction which discusses all that is in the body of the article. Various temperatures are then provided for thermal annealing of Boron oxide or GO mixture

The Role of Hong Kong in International Trade Research Paper - 1

The Role of Hong Kong in International Trade - Research Paper Example   The greatest financial activity in Hong Kong is international trade and its government policies in terms of trade demonstrate its position as a hub for free trade. These policies comprise of minimum constraints and permit the market dynamics to standardize exportation and importation activities. It thus prohibits protective actions such as tariffs and rations as well as subsidizations as a method of circumventing deficits that may be experienced in balances-of-trade. â€Å"Much of the impetus driving the changing patterns of global trade since 1950 can be attributed to the role played by transnational corporations which are sometimes called multinational corporations†. Development of Hong Kong’s import and export industry.The activities associated with the import and export industry can be categorized as imports, domestic exports and re-exports and Hong Kong have embraced a free trade policy while erecting limited barriers to trade. â€Å"Adopting pro-export policy promoting exports through tax breaks, subsidies, and tariffs, and at the same time discouraging imports through taxes, duties, or quotas, is a common practice among emerging markets and developing nations†.There is no imposition of tariffs in Hong Kong in regard to importing and exporting goods, and the licensing requirements are maintained at a minimum. The imposition of licensing only takes place in the event that there is a genuine need for meeting obligations that are undertaken by Hong Kong to its partners in trade.
