Facing seawater splitting challenges by regeneration with Ni-Mo-Fe bifunctional electrocatalyst for hydrogen and oxygen evolution
(2021-07-22)
Article
Restricted access - publisher's policyHydrogen, produced by water splitting, has been proposed as one of the main green energy vectors of the future if produced from renewable energy sources. However, to substitute fossil fuels, large amounts of pure water are ... -
Recycling of rare earths from fluorescent lamp waste by the integration of solid-state chlorination, leaching and solvent extraction processes
(2021-10-01)
Article
Restricted access - publisher's policyRare earths (RE) are currently considered some of the most critical elements, being crucial in future sustainable applications. Their high demand, price fluctuations, supply risk and geopolitical factors increase the ... -
Thermal effects of a sonic jet fire impingement on a pipe
(2021-07)
Article
Restricted access - publisher's policyAlthough the effects of jet fires are often limited to rather short distances, if their flames impinge on a pipe or a vessel collapse can occur in very short times. In such cases, the heat flux on the affected equipment ... -
An improved hybrid strategy for online dosage of hydrogen peroxide in photo-Fenton processes
(Elsevier, 2021-06)
Article
Open AccessThis work addresses the challenge of designing H2O2 dosage strategies for improving photo-Fenton applications, as well as for further understanding the effect of the dosage. The developed strategy focuses on the limitations ... -
