A New Approach for Orbital Wall Reconstruction in a Rabbit Animal Model Using a Hybrid Hydroxyapatite-Collagen-Based Implant.

Reconstructing the orbit following complex craniofacial fractures presents significant challenges. Throughout the 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 been reached on the optimal material for orbital restoration.

Composite Polymer for Hybrid Activity Protective Panel in Microwave Generation of Composite Polytetrafluoroethylene -Rapana Thomasiana.

During the microwave sintering of a polymer-ceramic composite plasma discharge is experienced. The discharge could occur failure of the power source. The solution proposed by the paper is original, no similar solutions being presented by the literature.

Nanostructured Cobalt Doped Barium Strontium Titanate Thin Films with Potential in CO Detection.

In this work, (BaSr) (TiCo) O perovskite nanostructured material, denoted subsequently as Co-doped BaSrTiO, was synthesized in a one-step process in hydrothermal conditions. The obtained powder was heat-treated at 800 °C and 1000 °C, respectively, in order to study nanostructured powder behavior during thermal treatment. The Co-doped BaSrTiO powder was pressed into pellets of 5.

One-Step Soft Chemical Synthesis of Magnetite Nanoparticles under Inert Gas Atmosphere. Magnetic Properties and Study.

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 to control the synthesis parameters of nanostructured iron oxides in order to obtain magnetite nanoparticles in a single step, in environmentally friendly conditions, under inert gas atmosphere.

The Influence of Synthesis Parameters on Structural and Magnetic Properties of Iron Oxide Nanomaterials.

Magnetic iron oxides have been used in biomedical applications, such as contrast agents for magnetic resonance imaging, carriers for controlled drug delivery and immunoassays, or magnetic hyperthermia for the past 40 years. Our aim is to investigate the effect of pressure and temperature on the structural, thermal, and magnetic properties of iron oxides prepared by hydrothermal synthesis at temperatures of 100-200 °C and pressures of 20-1000 bar. It has been found that pressure influences the type of iron oxide crystalline phase.

Residual titanium flakes as a novel material for retention and recovery of rare earth and relatively rare earth elements.

The aim of this study was the valorization of titanium flakes (waste) from titanium and titanium alloy ingot production factories and using in applications related to metals recovery as retention bed for some trace metals. The titanium flakes were anodized for surface nanostructuration with TiO nanotubes and then annealed in order to increase the surface stability. The nanostructured titanium flakes were loaded and pressed in a retention column linked with inductively coupled plasma spectrometer (ICP-OES).
