Ferrimagnetic glass-ceramics are potential candidates for magnetic induction hyperthermia [1]. The aim of this work is the preparation and characterization of innovative bioactive ferrimagnetic glass-ceramics in the system SiO2– Na2O–CaO–P2O5–FeO–Fe2O3. These biomaterials contain different amounts of nanometric or sub-micrometric magnetite crystals, homogeneously distributed in an amorphous mat...

In recent years, significant progress has been made in the development of new technologies to meet demand for engineered interfaces with appropriate properties osteochondral unit repair and regeneration. this context, we combined two methodologies that have emerged as powerful approaches tissue engineering application: electrospinning fabricate a nanofibrous polymeric scaffold pulsed laser depo...

To study the cooperative dynamics in a superconductive ceramic or a Josephson-coupled network, the ordering process in a sintered specimen of YBa2Cu4O8 was examined. Critical phenomena at the intergrain phase transition in the system were considered based on recent experimental facts by nonlinear magnetic and linear and nonlinear electric response observations. Compared with theoretical predict...

The regenerator glass-ceramic is produced as a honeycomb product for a turbine engine heat exchanger. It is made from a powdered glass frit, which as a slurry can impregnate paper that is wound as alternately corrugated sheets on a wheel. After firing, a porous ceramic regenerator wheel is produced that allows energy to be transferred from hot exhaust gases to the cold intake air in the turbine...

This study was carried out to determine the design and thickness of the cervical margin of a castable ceramic restoration from the point of view of its castability. Castability of castable ceramics was lower compared to Ag-Pd-Au and Co-Cr alloy with the use of the mesh pattern and rod pattern test (p < 0.05). It was more dependent on the pattern thickness than alloys (p < 0.05), and perfect rep...

Quaternary glasses with the composition 50SiO2 – 25TiO2 5La2O3 (20-x) Na2O xY2O3 where x : (0 ≤ ≥ 10) were synthesized using melt-quench technique. XRD examined nature of prepared glasses. UV-spectroscopic investigated glass system studied at room temperature. Both optical bandgap and refractive index present have been increased. The polarizability basicity determined. Thermal parameter values ...

While ceramics are important materials for electronic and microsystem packaging, they are difficult to pattern lithographically. LEEDUS, a fabrication process combining lithography, electroplating, batch mode micro electro-discharge machining (µEDM) and batch mode micro ultrasonic machining (µUSM), is presented in this paper. This technology provides die-scale pattern transfer capability from l...

A new forcefield model was developed for the computer simulation of phosphate materials that have many important applications in the electronics and biomedical industries. The model provides a fundamental basis for the evaluation of phosphate glass structure and thermodynamics. Molecular dynamics simulations of a series of lithium phosphate glass compositions were performed using the forcefield...

The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....
