Ruthenium Nanoparticles Media with in Ionic Liquid in Carbon Dioxide Valorisation to Methane

Bogel-Łukasik E., LAQV/Universidade Nova de Lisboa, PT

Carbon dioxide (CO2) is a very stable molecule and hydrogen reduction of CO2 to produce CO, the reverse water-gas shift reaction, only becomes thermodynamically favourable at temperatures higher than 1110K. CO2 emissions resulting from the [...]

Design of a novel melatonin Pickering emulsion sunscreen

Ribeiro H., Faculdade de Farmácia cda Universidade de Lisboa, PT

Melatonin, the main secretory product of the pineal gland, was recently found to have a protection effect against photocarcinogenesis based on its free radical scavenger and antioxidant activity. On the other hand, the daily use [...]

Synthesis, Characterization and magnetic properties of Graphene /Nickel nanocomposites: The role of reducing agent on nanoparticle size and morphology

Salimian M., Titus E., Goncalves G., Bdkin I., Ferro M., Ventura J., Dias C.C., Nanoengineering Research Group (NRD), PT

Graphene oxide (GO) synthesized by modified Hummers used as substrate for the controlled growth of nickel nanoparticles via hydrothermal treatment. Hydrazine hydrate were used as a complex agent for the effective control of the size, [...]
