A technique was developed for the preparation of transparent, thin film epoxy samples for direct TEM investigation of the activation of epox:r and the initiation of the electroless Cu reaction. Associated EDX measurements determined the composition of the nucleated Cu particles. The steps of activation with a Pd-Sn colloidal catalyst, acceleration with NaOH, HC1, or EDTA, and initiation of electroless Cu plating were studied individually. All of the accelerators were effective in removing tin from the surface and increasing the initial rate of Cu deposition. The Cu distribution on the epoxy was determined by the accelerator, with NaOH and EDTA giving the most uniform distributions.
With development of IT technology, B2C Social Commerce makes the change from closed type of transaction to the form of an open trading. Also by dramatically reducing the intermediate distribution and removing distribution costs, it provides goods at unbeatable prices to consumers. Depending on the flow of the times, the business-to-business struggles with the difficulty of PRM management and fast promotion of new products. Therefore, it is required B2B Social Commerce, new platform that can collect distribution and consumption firms in one place which is similar to B2C Social Commerce. Unlike the case of B2C social commerce, B2B Social Commerce should have an essential element, Installment payment system to pay over the period without purchase in accordance with the payment paid as a lump sum. B2B Social Commerce model which is introduced in this study will provide the solution of B2B transaction problems, opening up new markets and bring the expansion of the electronic market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
