O escândalo da falência da Companhia Geral do Crédito Predial Português na agonia da Monarquia Constitucional (1910)

The goal of this article is to study the journalistic coverage of a bank's insolvency in 1910: the company Crédito Predial Português. We intend to evaluate how the press of the time - particularly, those positioned against the Government and/or the political regime: O Século, O Dia and O Mundo- covered this scandal. Using quantitative and the qualitative methods, we will assess the framing of the news stories, and the tone and language used. We also want to study the role that sources played ...

On the stability enhancement of cuprous oxide water splitting photocathodes by low temperature steam annealing

Given the intermittent nature of solar radiation, the large-scale use of solar energy requires an efficient energy storage solution. So far, the only practical way to store such large amounts of energy is in the form of a chemical energy carrier, i.e., a fuel. Photoelectrochemical (PEC) cells offer the ability to convert solar energy directly into chemical energy in the form of hydrogen. Cuprous oxide (Cu2O) is being investigated for photoelectrochemical solar water splitting since it has a b...

Ultra-long Fe nanowires by pulsed electrodeposition with full filling of alumina templates

With the increasing demand for high quality methods for the fast fabrication of extremely high aspect ratio nanoparticles, the research for efficient, low-cost and simple techniques has become fundamental. A promising approach on the synthesis of these materials is here addressed. Pulsed electrodeposition in porous anodic alumina templates was improved enabling, for the first time, a simple and cost effective fabrication method for vertically aligned nanomaterials with aspect ratios never rep...
