Magnetic iron oxides have been used in biomedical applications, such as contrast agents for magnetic resonance imaging, carriers controlled drug delivery and immunoassays, or hyperthermia the past 40 years. Our aim is to investigate effect of pressure temperature on structural, thermal, properties prepared by hydrothermal synthesis at temperatures 100–200 °C pressures 20–1000 bar. It has found that influences type oxide crystalline phase. Thus, results obtained Mössbauer characterization are...
This study investigates the additive manufacturing of 3D porous scaffolds based on walstromite-type silicate ceramics for bone tissue engineering applications. Walstromite powders were synthesized using sol-gel method and printed extrusion-based printing. Both sintered unsintered characterized scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) energy dispersive X-ray (EDS) analyses to evaluate effects sintering microstructure,...
Lithium lanthanum titanate (LLTO) is a very promising material due to its ability conduct lithium ions. It has many potential applications in the field of batteries and sensors. Typical synthesis methods include solid-state reaction sol–gel synthesis. We report novel solvothermal method that produces almost single-phase LLTO samples at significantly reduced costs. The thus obtained were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), electrical impedance...
Monazite is one of the most valuable natural resources for rare earth oxides (REOs) used as dopants with high added value in ceramic materials extreme environments applications. The complexity separation process individual REOs, due to their similar electronic configuration and physical–chemical properties, reflected products price environmental footprint. During last years, there was an increasing interest using different mixtures REOs temperature ceramics, particular ZrO2-based thermal...
Iron oxide nanoparticles have received remarkable attention in different applications. For biomedical applications, they need to possess suitable core size, acceptable hydrodynamic diameter, high saturation magnetization, and reduced toxicity. Our aim is control the synthesis parameters of nanostructured iron oxides order obtain magnetite a single step, environmentally friendly conditions, under inert gas atmosphere. The physical–chemical, structural, magnetic, biocompatible properties...
In this work, (Ba0.75Sr0.25) (Ti0.95Co0.05) O3 perovskite nanostructured material, denoted subsequently as Co-doped BaSrTiO3, was synthesized in a one-step process hydrothermal conditions. The obtained powder heat-treated at 800 °C and 1000 °C, respectively, order to study behavior during thermal treatment. BaSrTiO3 pressed into pellets of 5.08 cm (2 inches) then used for thin film deposition onto commercial Al2O3 substrates by RF sputtering method. microstructural, thermal, gas sensing...
Owing to its extraordinary range of properties, yttria-doped zirconia holds a unique place among the ceramic oxide systems. To improve properties for some specific custom design applications, co-doping with other rare earth oxides such as ceria is needed. The aim this paper identify correlations between phase composition evolution increasing thermal treatment temperature in order establish stability connection content and how does it influence yttria-stabilised microstructure....
During the microwave sintering of a polymer-ceramic composite plasma discharge is experienced. The could occur failure power source. solution proposed by paper original, no similar solutions being presented literature. It consists using protective panel, to stop entrance guiding tunnel. Six composites resulted combining three polymers, Polytetrafluoroethylene (PTFE), STRATITEX and Polyvinylchloride (PVC) with two natural ceramics containing calcium carbonate: Rapana Thomasiana (RT)...
This study investigates the application of robocasting technology for fabricating high-density yttria-stabilized zirconia (8YSZ) electrolytes used in solid oxide fuel cells (SOFCs). The primary goal is to overcome limitations traditional manufacturing techniques, such as low density and poor microstructural control. Using a combination hydrothermal synthesis, rheological testing, robocasting, we achieved dense 8YSZ structures (over 95% density) with minimal porosity. fabricated underwent...
Reconstructing the orbit following complex craniofacial fractures presents significant challenges. Throughout years, several materials have been used for orbital reconstruction, taking into account factors such as their durability, compatibility with living tissue, cost efficiency, safety, and capacity to be adjusted during surgery. Nevertheless, a consensus has not yet reached on optimal material restoration. This study investigates potential of hybrid hydroxyapatite–collagen (HAp-COL)...
