Electroreduction of carbon dioxide into higher-energy liquid fuels and chemicals is a promising but challenging renewable energy conversion technology. Among the electrocatalysts screened so far for carbon dioxide reduction, which includes metals, alloys, organometallics, layered materials and carbon nanostructures, only copper exhibits selectivity towards formation of hydrocarbons and multi-ca...
We analyse in detail our experimental data, our simulation results and data from the literature, for the adsorption of argon, nitrogen, carbon dioxide, methanol, ammonia and water on graphitized carbon black (GTCB), and show that there are two mechanisms of adsorption at play, and that their interplay governs how different gases adsorb on the surface by either: (1) molecular layering on the bas...
young individuals ws-as demonstrated to be secondary to the presence of arteriosclerosis and not to cardiac decompensation as had previously been concluded. It was also found that in the series studied the increased venous and cerebrospinal fluid pressures were not of sufficient magnitude to affect the cerebral circulation. The factor of a decreased arterial carbon dioxide tension as a cause fo...

Activation of carbon dioxide is the most important step in its conversion into valuable chemicals. Surfaces of stable oxide with a low work function may be promising for this purpose. Here we report that the surfaces of the inorganic electride [Ca24Al28O64](4+)(e(-))4 activate and split carbon dioxide at room temperature. This behaviour is attributed to a high concentration of localized electro...
In this study, an attempt is made to investigate the effect of energy consumption on environmental pollution in Iran. For this purpose, a basic model (the whole economy) and three sectoral models (household, commercial and public; industry and transportation) has been estimated with an autoregressive distributed lag approach in the period 1971-2017. The results of the model estimation show the ...
