“…36 Alternatively, the authors proposed that the large volume fraction of Li-rich zones in the alloy results in preferential oxidation of Li compared to Mg. 36 The difference in Nernst potentials of Li and Mg may enable more oxidation of Li compared to Mg, as is commonly seen for alloys comprised of components with substantially different Nernst potentials. 6,13,[40][41][42] In the case of a congruently corroding binary alloy, the anodic charge was equally distributed between each element according to the composition ratio of the alloy. The procedure developed in Case Study I applicable to congruent dissolution of a corroding A-B alloy represented by a given…”

“…Materiais metálicos porosos são considerados um dos materiais funcionais mais promissores, tendo papel crucial em vários campos, tais como energia, meio ambiente, metalurgia, química, indústrias médicas, dentre outros [125][126][127][128]. Estes materiais não só herdam as características intrínsecas (por exemplo, condutividade elétrica e térmica, plasticidade e soldabilidade) de suas matérias-primas, mas também exibem novas vantagens: grande área superficial;…”

“…permeabilidade, tamanho e distribuição dos poros controláveis; composição versátil; capilaridade e outras mais [125][126][127]. Com base nestas propriedades, eles têm sido amplamente utilizados para a filtração e separação, distribuição de fluxo, permuta de calor, catalisadores, sensores, células a combustível, etc [125][126][127][128][129][130].…”

“…Tal comportamento pode ser explicado por limitações difusionais das espécies dissolvidas dentro dos nanoporos formados, levando a um aumento local sobre a concentração iônica e assim aumentando o potencial necessário para a dissolução, o que afetaria sua taxa [106].…”
