Indicator-based multi objective evolutionary algorithms and an application in f...
Yevseyeva, Iryna; de Melo, Francisco Queirós; Grácio, José; Basto-Fernandes, VitorThis work presents recent developments on multi objective evolutionary algorithms, so-called set-based evolutionary algorithms. These techniques are shown to approximate a Pareto front of efficient solutions taking into account both quality of the approximation and its diversity, both important in the design of these methods. Set-based evolutionary algorithms outperform their predecessors on a variety of benchm...
Automated high-throughput screening of carbon nanotube-based bio-nanocomposites...
Gonçalves, Paula P.; Singh, Manoj K.; Silva, Virgília S.; Marques, Filipa; Marques, Ana; LeDuc, Philip R.; Grácio, José; Marques, Paula A. A. P.In this work we demonstrate the potential of using an automated cell viability analyzer for developing high-throughput screening of orthopedic bioactive materials. We used a biomaterial of carbon nanotubes (CNTs)-based composite integrated with hydroxyapatite/ polymethyl methacrylate (HA/PMMA) with controlled physical and chemical properties to evaluate the usefulness of morphometric analysis in conjunction wit...
Graphene oxide modified with PMMA via ATRP as a reinforcement filler
Gonçalves, Gil; Marques, Paula A. A. P.; Barros-Timmons, Ana; Bdikin, Igor; Singh, Manoj K.; Emami, Nazanin; Grácio, JoséGraphene is a two-dimensional new allotrope of carbon, which is stimulating great curiosity due to its superior mechanical, electrical, thermal and optical properties. Particularly attractive is the availability of bulk quantities of graphene (G) which can be easily processed by chemical exfoliation, yielding graphene oxide (GO). The resultant oxygenated graphene sheets covered with hydroxyl, epoxy and carboxyl...
