Ballistic performance, at effective strain rates of (10–10 s ), for polymeric dicyclopentadiene (pDCPD) was compared with two epoxy resin/diamine systems with comparable glass transition temperatures. The high rate response was characterized in terms of a projectile penetration kinetic energy, KE50, which describes the projectile kinetic energy at a velocity with a 50% probability of sample pen...
Bisphosphonates (BPs) are a class of synthetic pyrophosphate analogs that can prevent the loss of bone mass, given orally to treat postmenopuasal osteoporosis. It is not clear yet if the benefits of BPs include the possibility of affecting bone apatitic precursors transition for bone consolidation except for encouraging osteoclasts to undergo apoptosis. Furthermore, the complexity of the in viv...
In this paper, we investigate the effect of substituting SrO for CaO in silicate and phosphate bioactive glasses on the human gingival fibroblast activity. In both materials the presence of SrO led to the formation of a CaP layer with partial Sr substitution for Ca. The layer at the surface of the silicate glass consisted of HAP whereas at the phosphate glasses it was close to the DCPD composit...
Calcium phosphate bone cements (CPCs) with antibacterial properties are demanded for clinical applications. In this study, we demonstrated the use of a relatively simple processing route based on preparation of silver-doped CPCs (CPCs-Ag) through the preparation of solid dispersed active powder phase. Real-time monitoring of structural transformations and kinetics of several CPCs-Ag formulation...
Low dielectric constant (k) polymers with excellent comprehensive properties are useful materials in the microelectronics industry as matrix resins or encapsulation layers. With inherent low polarization, high reactivity, good processability, and cost, poly(dicyclopentadiene) (PDCPD) has received considerable attention low-k materials. However, its practical application is limited by relatively...
