Humidity-sensitivity of yttrium substituted apatite ceramics

The effect of functional ions (Y3+, F−, Ti4+) on the structure, sintering and crystallization of diopside-calcium pyrophosphate bioglasses

“…Also, it has been demonstrated that the presence of yttrium in biomaterials increases their electrical conductivity [10], which could be beneficial for bone regeneration, as cell proliferation has been shown to be sensitive to electrical currents [11]. Although the optimum concentration level of yttrium for promoting osteoblast differentiation and proliferation is still ambiguous, the beneficial aspects of this element have been reported to be dosedependent [12].…”

Optical characterization of infrared emitting Nd3+ doped hydroxyapatite nanoparticles prepared by hydrothermal method

“…The advantages of doping HAp with foreign elements pertinent to orthopaedic applications were reported by others. For example, Y-doped hydroxyapatite [21] has been studied for humidity sensor applications due to its high affinity for water molecules [22]. The doping of HAp with Zn 2+ significantly increased osteoblast adhesion [23].…”

Preparation of Yttrium Phosphate and Yttrium‐Doped Calcium Phosphate Microspheres via Hydrated Ions Exchange

“…Y‐doped calcium phosphate (CaP) materials were reported to show increased adsorption of fibronectin and vitronectin to material compound surface, and promote cytocompatibility for osteoblasts adhesion as compared to regular CaP materials . Moreover, Y‐doped CaP materials were also observed to improve mechanical strength, electrical conductivity, stability, and hydrophilicity, showing potentials in varied applications in addition to tissue engineering.…”
