Vascularization of bone tissue constructs plays a pivotal role in facilitating nutrient transport and metabolic waste removal during the processes of osteogenesis and bone regeneration in vivo.In this study, a sildenafil (Sil)-loaded nanofibrous scaffold of keratin/Soluplus/merwinite (KS.Me.Sil) was fabricated through electrospinning and the …
The main minerals in stainless steel slag are merwinite (Ca 3 Mg(SiO 4) 3), dipside (CaMg(SiO 3) 2), magnesium aluminum oxide (MgO.Al 2 O 3) and magnesium silicate (β-2MgO.SiO 2).The slag has latent hydraulic properties. Mixing CAS with the slag accelerates the formation of CaO.SiO 2.H 2 O and CaO.Al 2 O 3.SiO 2.H 2 O. These hydrates are considered to be contributing to …
3 and merwinite) and diamond at an early stage, and (Mg 0.86 Fe 0.14) 2 SiO 4 oliv-ine and diamond at a later stage, after the Ca-Mg exchange between carbonatite melt and peridotite has ceased. This scenario is supported by the presence of calcite microinclusions within merwinite. Keywords: Merwinite, diamond, Earth's mantle, calcic lithology ...

Merwinite is prepared using sol–gel method that shows the phase formation at 900 °C and investigation of bioactivity confirmed the deposition of apatite when immersed in simulated body fluid [11]. Further surfactant assisted sol–gel process was adopted to synthesize the single phasic merwinite at 850 °C without impurities [12].
