  • Impact of the crisis on marketing activities and management of company

    In a crisis, the lack of market information, enterprise management deficiencies make weak, lacking immunity to environmental changes. Possession of full information about the market and carefully developed on the basis of this strategy becomes a kind of protection companies in any economic environment. Crisis opens visionary companies huge business prospects. He usually initiates redistribution of the market and here are the winners of which will be able to use the opportunities presented by the downturn. In these circumstances, the company purchased a flexible active marketing policy for a soft exit from the crisis or prevent it by adequate anti-crisis measures and effective management of the company.

  • Study of possible cathode intercalation of alkali metal platinum under an alternating pulse current

    • Abstract

    The work investigated the cathode intercalation process alkali metal platinum under the influence of the alternating pulse current of aqueous and non-aqueous solutions containing alkali metal cations. By means of the method of pulse chronopotentiometry found that processes taking place at the platinum cathode polarization in water (neutral and alkaline) and in non-aqueous electrolytes include electrochemical adsorption and intercalation of solvent molecules into the adsorption layer of alkali metal ions. When this surface is oxidized in the intercalation platinum milder than pure platinum.
