No seio da bela Sebastianópolis: uma cartografia do Rio de Janeiro nas crônicas de Macedo e Alencar nas décadas de 1850 e 1860

O presente trabalho pretende analisar as representações da cidade do Rio de Janeiro nas crônicas de José de Alencar e Joaquim Manuel de Macedo, publicadas, respectivamente, sob os títulos Ao Correr da Pena (1855-1856) e Labirinto (1860), tendo como objetivo mapear a cidade capital do império e as transformações pelas quais passou entre as décadas de 1850 e 1860. Tal proposta foi desenvolvida à luz do método cartográfico apresentado por Franco Moretti, em suas obras Atlas do Romance Europeu 1800-1900 e A Literatura Vista de Longe, nas quais o autor trata a criação de mapas como um instrumento intelectual que abriria caminho para novos questionamentos e novas conclusões no campo do imaginário. Ademais, ao utilizar obras literárias como fontes primárias para a análise da cidade do Rio de Janeiro do século XIX e suas especificidades no cenário brasileiro imperial, o presente trabalho dialoga com uma história cultural do urbano.

Structure and reactivity of the Ru(0 0 0 1) electrode towards fuel cell electrocatalysis

The reactivity of the Ru(0 0 0 1) electrode towards the adsorption and electrooxidation of CO and methanol has been studied by variable-temperature in situ FTIR spectroscopy in both perchloric acid and sodium hydroxide solution, and the results interpreted in terms of the surface chemistry of the Ru(0 0 0 1) electrode. Both linear (CO) and threefold hollow (CO) binding CO adsorbates (bands at 1970-2040 and 1770-1820 cm, respectively) were observed on the Ru(0 0 0 1) electrode in both 0.1 M HClO and 0.1 M NaOH solutions from the CO adsorption. In the acid solution, CO was detected as the main adsorbed species on Ru(0 0 0 1) surface over all the potential region studied. In contrast, in the alkaline solution, more CO than CO was detected at lower potentials, whilst increasing the potential resulted in the transformation of CO to CO. At higher potentials, the oxidation of the adsorbed CO took place via reaction with the active (1 × 1)-O oxide/hydroxide. It was found that no dissociative adsorption or electrooxidation of methanol took place at the Ru(0 0 0 1) at potentials below 900 mV vs Ag/AgCl in perchloric acid solution at both 20 and 55°C. However, in the alkaline solution, methanol did undergo dissociative adsorption, to form linearly adsorbed CO (CO) with little or no CO adsorbed at threefold hollow sites (CO) at both 20 and 55°C. Increasing the temperature from 20 to 55°C clearly facilitated the methanol dissociative adsorption to CO and also enhanced the electrooxidation of the CO. At the higher potentials, significant oxidation of methanol to CO and methyl formate in acid solution and to bicarbonate and formate in alkaline solution, was observed, which was attributed to the formation of an active RuO phase on the Ru(0 0 0 1) surface, in agreement with our previous studies. © 2003 Elsevier Ltd.
