Effect of the micromoulding process conditions on polymer flow behavior within ...
Zhiltsova, T. V.; Oliveira, M. S. A.; Ferreira, J. A.; Vasco, Joel Oliveira Correia; Pouzada, A. S.; Pontes, A. J.Fast time to market along with high level of automation and versatility made microinjection moulding, by far, a favorite technique for the mass production of microplastic components. In the microimpressions, very high shear rates develop, eventually leading to excessive shear heating and consequently to less predictable flow behaviour comparing to conventional injection moulding. In this study, the flow behavio...
In vitro studies of multiwalled carbon nanotube/ultrahigh molecular weight poly...
Reis,J.; Kanagaraj,S.; Fonseca,A.; Mathew,M.T.; Capela-Silva,F.; Potes,J.; Pereira,A.; Oliveira,M.S.A.; Simões,J.A.Carbon nanotubes are highly versatile materials; new applications using them are continuously being developed. Special attention is being dedicated to the possible use of multiwalled carbon nanotubes in biomaterials contacting with bone. However, carbon nanotubes are also controversial in regards to effects exerted on living organisms. Carbon nanotubes can be used to improve the tribological properties of polym...
