<i>The formation of carbon chains by the coupling of COx (X = 1 or 2) units on transition metals is a fundamental step relevant to Fischer-Tropsch catalysis. Fischer-Tropsch catalysis produces energy dense liquid hydrocarbons from synthesis gas (CO and H2) and has been a mainstay of the energy economy since its discovery nearly a century ago. Despite detailed studies aimed at elucidating the steps of catalysis, experimental evidence for chain growth (Cn to Cn+1 ; n > 2) from the reaction of CO with metal complexes is unprecedented. In this paper, we show that carbon chains can be grown from sequential reactions of CO or CO2 with a transition metal carbonyl complex. By exploiting the cooperative effect of transition and main group metals, we document the first example of chain propagation from sequential coupling of CO units (C1 to C3 to C4), along with the first example of incorporation of CO2 into the growing carbon chain.</i><br>

Modernisation of the agricultural, industrial and household sectors causes the demand for energy to increase more rapidly than its supply. In countries that aim to modernise quickly a heavy investment is required to redress this imbalance. That is why in countries such as Pakistan, the energy has remained on the top of the agenda of loan negotiation with international donor agencies. Energy serves as both a final consumption good and as an essential intermediate input in the production of goods. Thus any change in the price of energy at both these levels affects consumption as well as production and that, in turn, can cause changes in the prices of all other commodities. A change in the prices of exportables affects their demand in foreign markets and any change in the prices of import-competing and nontraded goods affects their demand at home. The net effects of all these changes can be measured in terms of the effects on real GDP, balance of trade, and government revenue. And, because any change in commodity prices exerts a negative impact on real consumption of households; the formulation of a comprehensive energy policy requires a framework that can take the immense complexity of the linkages of all the sectors of the economy into consideration. In the book under review, Dr Farzana Naqvi, argues that the issues of energy pricing can not be examined in isolation and presents a general equilibrium framework to address the complex issues related to energy, economy and equity.

The Technological University of Bahía de Banderas offers the career of Advanced University Technician and Engineering in Renewable Energies. Considering that its program of studies is 70% practical and 30% theory, it is of the utmost importance to have inside a system that serves to perform tests of operation and assembly of hybrid systems (wind, photovoltaic) so that students can acquire the necessary skills to a demanding work field. In addition, a space for solar pumping is contemplated, due to one of the eco-economic areas of the regios; agriculture and livestock, although there are irrigation channels there are remote areas with water needs. It is intended to use equipment, accessories and conditions attached to a common facility in the field of work, so that students when they arrive at a private facility are familiar with real, not theoretical marks, models and diagnoses, as the academic modules normally do. of manufacturers.
