The Rate of Economic Growth and the Socio-Cultural Current

The increase of spendings with the prices of raw materials, energy and fuel has eventually, and almost inevitably, led to an unexpected rise in the demand for currency, a demand coming from the goods and services suppliers. The resulting effect was the surging of an accelerated inflationist wave, which in turn, produced the first warnings of a looming economic breakdown. From this point onwards, different other expenses became directly or indirectly engaged in relation to the volume of incorporated raw materials, to the employement of a highly skilled workforce, or to the necessity of technical equipment and machinery modernization. Starting from Peter M. Chisnall’s work, “Marketing: a behavior analysis” (3rd edition, McGraw-Hill, London, 2000), this study follows the interdependence of the behalf of goods manufacturers and managers, and on the other hand, behavioural attitudes on behalf of buyers and consumers; also exhibited and of importance are the stands taken by both sides in approaching an optimal strategy for their situation. At the same time, there is a clear indication of the impact socio-cultural changes exercises upon the dynamics and typologies of economic structures.socio-cultural fluxes, economic development and impact, protection management, technological research, consumption demand

Iron-oxide-based nanoparticles produced by pulsed infrared laser pyrolysis of Fe(CO)2

International audienceThe synthesis of nanosized ( 1-100 nm) particles is an active research field in chemical processing technologies. The process may be of particular relevance in the case of the widely used iron-based materials. In this paper, we report on the preparation and characterization of ultrafine powders produced by pulsed infrared laser pyrolysis of iron pentacarbonyl, Fe(CO)5, in sensitized mixtures. The synthesis is performed in a flow reactor, at rather high pressure (400 mbar) and high laser fluence ( ~ 5 J cm−2). The average diameter of the particles is 30 nm. Different characterization methods of the fine powder aged in atmosphere indicate the presence of a substantial oxidic portion, identified as the β-Fe2O3 * H2O form. Some experimental observations suggest the possibility of iron-oxides formation during synthesis in th
