Recovery of Nd3+ and Dy3+ from E-Waste Using Adsorbents from Spent Tyre Rubbers
Nogueira, Miguel; Matos, Inês; Bernardo, Maria; Pinto, Filomena; Fonseca, Isabel; Lapa, Nuno© 2024 by the authors Licensee MDPI, Basel, Switzerland.; This paper investigates the use of spent tyre rubber as a precursor for synthesising adsorbents to recover rare earth elements. Through pyrolysis and CO2 activation, tyre rubber is converted into porous carbonaceous materials with surface properties suited for rare earth element adsorption. The study also examines the efficiency of leaching rare earth el...

Born Preterm
Pinto, Filomena; Fernandes, Eduardo; Virella, Daniel; Abrantes, Alexandre; Neto, Maria TeresaBackground: Prematurity accounts for about 10.6% of neonates worldwide and tends to increase as does survival from lower gestational ages. Summary: The importance of preterm birth in public health stems from its link to infant and under-5 mortality, morbidity, and its economic impact. In both the short and long term, preterm birth consequences are inversely related with gestational age and carry a higher risk o...
