The effect of loading rate (dK/dt) on the hydrogen environment-assisted cracking (HEAC) behavior Monel K-500 immersed in 0.6 M NaCl and polarized to −950 −1200 mVSCE was assessed via a slow-rising stress intensity (K) testing framework at dK/dt ranging from 0.2 20 MPa√m/hr. Comparative an inert environment (dry N2 with RH < 5%) 0.1 4 MPa√m/hr revealed clear dK/dt-dependence local plasticity eff...

Polydicyclopentadiene (pDCPD), a thermoset with excellent mechanical properties, has enormous potential as lightweight, tough, and stable matrix material owing to its highly cross-linked macromolecular network. This work describes generating pDCPD-based foams hierarchically porous carbons derived therefrom by combining ring-opening metathesis polymerization (ROMP) of DCPD, high internal phase e...

Segmental defect regeneration has been a clinical challenge. Current tissue-engineering approach using porous biodegradable scaffolds to delivery osteogenic cells and growth factors demonstrated success in facilitating bone regeneration in these cases. However, due to the lack of mechanical property, the porous scaffolds were evaluated in non-load bearing area or were stabilized with stress-shi...

Nowadays, hydorxyapatite (HA) is widely used as bioceramics in reconstructive surgery, in dentistry and as drug delivery materials due to the good biocompatibility and osteoconductivity [Hench, 1998]. One of the limitations for the usage of these materials is their low mechanical strength. Thus, many researchers focuses on the development of new biomaterials, that combine the osteoconductive ch...
