Biomimetic synthesis of bioceramics using simulated body fluid (SBF) is a route to produce biomaterials with a more suitable microstructure and characteristics required for bone defect treatments. As matter of fact, the biomimetic method allows us to imitate the natural environment needed for the synthesis of bone-like materials, such as hydroxyapatite (HA). In this study, biomimetic HA was successfully synthesized through the microwave-assisted method by the employment of SBF in different ratios with water as a solvent for precursors. Later, synthesized powders were sintered at four different temperatures (700°C, 900°C, 1100°C, and 1300°C), and their physicochemical properties, as well as microstructure and microhardness, were examined. Results depicted that synthesized biomimetic HAs are highly pure. They experienced larger particle size growth when exposed to higher sintering temperatures when compared to non-biomimetic HA. Moreover, density (porosity) and microhardness of biomimetic HAs, especially the one that used 100% SBF as a solvent for calcium precursor and sintered at 900°C, had closer value to the natural human femur and could serve as promising candidates for bone defect treatment application.

Effects of Isoflurane, Halothane, and Chloroform on the Interactions and Lateral Organization of Lipids in the Liquid-Ordered Phase
Türkyılmaz, Serhan; Regen, Steven L. (2011-12-06)
The first quantitative insight has been obtained into the effects that volatile anesthetics have on the interactions and lateral organization of lipids in model membranes that mimic "lipid rafts". Specifically, nearest-neighbor recogntion measurements, in combination with Monte Carlo simulations, have been used to investigate the action of isoflurane, halothane, and chloroform on the compactness and lateral organization of cholesterol-rich bilayers of 1,2-dipalmitoylsn-glycero-3-phosphocholine (DPPC) in the...
Effects of the doping concentration of boron on physicochemical, mechanical, and biological properties of hydroxyapatite
Jodati, Hossein; Tezcaner, Ayşen; Alshemary, Ammar Z.; Şahin, Volkan; Evis, Zafer (2022-01-01)
© 2022 Elsevier Ltd and Techna Group S.r.l.Ion doping is an approach to modify properties of materials, like hydroxyapatite (HA), that contributes to designing biomaterials with desired characteristics applicable in bone defect treatments. Recently, boron (B) has been noticed in biomaterial fields due to its beneficial effects on formation, growth, and quality of bone. In this study, B-doped HA nanoparticles with different molar concentrations of B (0.05, 0.1, 0.25, and 0.5) were synthesized through microwa...
Effect of fluorine substituted benzothiadiazole on electro-optical properties of donor-acceptor-donor type monomers and their polymers
Çakal, Deniz; Önal, Ahmet Muhtar (Elsevier BV, 2020-11-01)
A series of trimeric monomers bearing thiophene donor units and fluorinated analogues of benzothiadiazole acceptor units was synthesized via donor-acceptor-donor approach and polymerized electrochemically in order to investigate the effect of fluorine atom on electro-optical properties of both monomers and their corresponding polymers. All monomers exhibited solvatochromic and fluorescent properties. The introduction of fluorine atom into the conjugated backbone increased the oxidation potentials. Upon movi...
Effects of synthesis, doping methods and metal content on thermoluminescence glow curves of lithium tetraborate
Kayhan, Mehmet; Yılmaz, Ayşen (Elsevier BV, 2011-07-28)
Lithium tetraborate: Li(2)B(4)O(7), (LTB) has been synthesized and doped with various Mn content by different methods, such as, high temperature solid state synthesis and solution assisted synthesis methods. Powder XRD results proved the formation of solid-solution by replacing Mn with Li ions in LTB lattice at lower amount of Mn doping, for example 0.1-3.0% Mn doping. In this research TL glow curves of Mn doped lithium tetraborate (LTB: Mn) produced by using different synthesis and doping methods and the e...
Effects of oxidative functionalized and aminosilanized carbon nanotubes on the crystallization behaviour of polyamide-6 nanocomposites
Kaynak, Cevdet (2014-04-01)
The purpose of this study is to investigate effects of oxidative functionalized and aminosilanized carbon nanotubes on the (1) isothermal and (2) non-isothermal crystallization kinetics of polyamide-6 by DSC analyses, and (3) crystal structure of injection molded specimens by XRD analyses. Nanocomposites were compounded by using melt mixing technique via twin screw extrusion. Due to basically very effective heterogeneous nucleation effect, both increasing amount and surface functionalization of carbon nanot...
