Thallium and selenite doped carbonated hydroxyapatite: Microstructural features and anticancer activity assessment against human lung carcinoma

Nanofibrous ε-polycaprolactone scaffolds containing Ag-doped magnetite nanoparticles: Physicochemical characterization and biological testing for wound dressing applications in vitro and in vivo

“…The crystallite size in the polymeric phase was calculated using Scherrer's formula [ [40] , [41] , [42] ]: where D refers to the crystallite size in nm, k represents the shape factor (0.9), λ is the wavelength of the X-rays (1.54056 Å for CuK α radiation), while is the corrected full width at half maximum expressed in radians, and θ is the Bragg diffraction angle.…”

RETRACTION NOTICE: Mechanical, microstructural properties and cell adhesion of Sr/Se-hydroxyapatite/graphene/polycaprolactone nanofibers

“…Consequently, the ideal mimicking for bone regeneration must include multi-dopant HAP which reinforced with architectural fibers to balance between rigidity and flexibility of both ceramic and fiber. Synthetic HAP as a ceramic has its drawbacks; low mechanical properties restrict its load applications 18 ; however, HAP structure is tolerant to the ionic substitutions, 9,19,20 whereas substitution of trace elements may modify its physicochemical/biological behavior dramatically 9,19,21,22 such as; (Ag + , Ti 4+ , Zn 2+ , Sr 2+ , and SeO 3 2 − ) to show antibacterial activity, 23 (Mg 2+ and ZrO 2+ ) 23,24 to enhance its mechanical properties, (Eu 3+ and Gd 3+ ) to induce luminescence features, 25 or with Si 2+ , Sr 2+ , and F − to improve its osteoconduction. 26 In addition, it could be mentioned that the higher valence of the dopant than the host ion may enhance the bioactivity of the whole composition.…”

Evaluation of Calcium Oxide Nanoparticles from Industrial Waste on the Performance of Hardened Cement Pastes: Physicochemical Study

“…Considering the literature, some authors replaced OPC with 10% and 15% bagasse ash to optimize the replacement level of OPC, but these papers did not focus on the particle size when the waste was calcined to produce ultrafine nanopowder. Nanotechnology is a trend in many applications [28][29][30][31]. Pure CaO is used in many applications, such as the cement industry, biodiesel production, the petroleum industry, electric lighting, paper industry, and power production [32][33][34][35][36][37][38].…”
