Durability of an UHPC containing spent equilibrium catalyst
Matos, A. M.; Nunes, S.; Costa, C.; Aguiar, J. L. Barroso deUHPC is an advanced cementitious material able to meet the current construction industry challenges regarding structural safety and durability. However, new UHPC formulations with limited shrinkage are still being pursued to reduce residual tensile stresses in the UHPFRC layers, for rehabilitation/strengthening applications. This investigation estimates the durability of a non-proprietary UHPC incorporating a b...
Remote triggering of TGF-β/Smad2/3 signaling in human adipose stem cells laden ...
Matos, A. M.; Gonçalves, A. I.; Rodrigues, M. T.; Miranda, M. S.; Haj, A. E.; Reis, R. L.; Gomes, Manuela E.Injuries affecting load bearing tendon tissues are a significant clinical burden and efficient treatments are still unmet. Tackling tendon regeneration, tissue engineering strategies aim to develop functional substitutes that recreate native tendon milieu. Tendon mimetic scaffolds capable of remote magnetic responsiveness and functionalized magnetic nanoparticles (MNPs) targeting cellular mechanosensitive recep...
Characterization of non-proprietary UHPC for use in rehabilitation/strengthenin...
Matos, A. M.; Nunes, S.; Costa, Carla; Aguiar, J. L. Barroso deUHPFRC has become one of the most promising cement-based materials for the next generation of infrastructures because of its good workability, outstanding mechanical properties, and excellent durability. A promising field of application is the rehabilitation and/or strengthening of existing reinforced concrete structures, in which a new layer of UHPFRC replaces the deteriorated concrete (cracked, carbonated, ch...
Influence of micro-cracking on capillary water absorption of an UHPFRC
Matos, A. M.; Nunes, S.; Aguiar, J. L. Barroso deThe aim of this research was to investigate the influence of cracking on water transport by capillary suction in UHPFRC. Specimens were firstly pre-loaded under four-point bending up to a wide range of pre-defined crack open displacement. Crack pattern created was characterized (width, number of cracks) before capillarity testing. Test results showed that micro cracks induced by previous loading significantly i...
RFID-based smart blood stock system
Zaric, A.; Cruz, C. C.; Matos, A. M.; Silva, M. R.; Costa, J. R.; Fernandes, C. A.A complete UHF radio-frequency identification (RFID)-based system capable of localizing individual blood bags inside storage cabinet drawers is presented. It was developed to demonstrate the improvement possibility of current blood stock management systems and as the submission to the 2014 IEEE AP-S Student Design Contest: Antennas for RFID Application. The system is composed of a cabinet model, a transceiver u...
