There are several methods for the measurement of radon concentration or exposure, that use nuclear tracks detectors lodged into dosemeters with different geometries. It was necessary to determinate some calibration parameters of the new detector’s optical system in order to characterize instead of a semicylindrical a cylindrical dosemeter was used in this investigation. The new system we used i...

Shape memory polymers (SMPs) are a class of polymeric materials used in various medical interventions such as vascular stents. In this work, two SMPs, thermoplastic (TP) and thermoset (TS), have been measured in vitro for the degree of cellular and protein adhesion, their ability to stimulate inflammatory cytokine production, as well as the effects of the SMPs on the haemostatic system. The sti...

Self-healing was achieved with a dual-microcapsule epoxy-amine chemistry in thermoset epoxy. One capsule contained a modified aliphatic polyamine (EPIKURE 3274) while the second capsule contained a diluted epoxy monomer (EPON 815C). Amine microcapsules were prepared by vacuum infiltration of EPIKURE 3274 into hollow polymeric microcapsules. Epoxy microcapsules were prepared by an in situ polyme...

Industrial humins from biorefining process of sugars were used as reactive thermoset matrix for the preparation humins-jute fibre composites. This material was investigated and benchmarked with jute composites prepared polyfurfurylalcohol (PFA), a well-known biobased thermosetting resin The Dynamic Mechanical Analyses (DMA) showed glass transition temperature (Tg) associated to relaxation cross...
