3^rd International Conference and Expo on Ceramics and Composite Materials June 26-27, 2017 Madrid, Spain

De Aza P N studied Chemistry-Ceramics at the Santiago de Compostela University, where she received her Doctoral Degree in 1995. She did a Postdoctoral stage at the IRC in Biomaterials at the Queen Mary & Wetsfield College, University of London (UK) working on in vitro and in vivo behavior of Bioceramics. At this moment, she is the Chair of the Materials Science, Optic and Electronic Technology Department, Professor of Materials Science and Metallurgical Engineering and Researcher at the Bioengineering Institute at the Miguel Hernandez de Elche University.

In the present study, a new single phase Si-Ca-P based ceramic (called Nurse´s Ass) was obtained and it´s in vitro behaviour for potential bone tissue regeneration was explored. Porous Si-Ca-P (Nurse´s Ass) single phase ceramic was obtained from high temperature sintering of γ-dicalcium silicate and β-tricalcium phosphate previously synthetized. The apatite-mineralization ability and dissolution rate have been systematically studied by immersion of the material in simulated body fluid (SBF) for several periods of time. A massive formation of a new dense calcium deficient hydroxyapatite (CDHA) layer was observed at the SBF-sample interface. Adjacent to the dense CDHA layer a porous structure has been developed parallel to the interface which is formed by pseudomorphic transformation of the Si-Ca-P (Nurse´s Ass) into CDHA. In addition, cell attachment test showed that the new material supported the adult human bone marrow-derived mesenchymal stem cells (hMSCs) adhesion and spreading; the cells established close contact with the ceramic surface in an extended culture of 28 days (Figure 1). In view of the results, Nurse´s Ass ceramic should be an effective substrate promoter of bone tissue regeneration suitable for bone tissue bioengineering. Future performance should be led using standard biomaterials, such as Si-HA or Si-TCP. The Nurse´s Ass biological performance should be investigated as proposed in International Standard ISO-10993-5.

Jesús Ma Rincon is a Senior Research Professor (Profesor de Investigación) at the Instituto E Torroja de Ciencias de la Construcción, CSIC, Madrid, where he is the Founder and Head of the Glass-Ceramics Laboratory. He was General Secretary of the Spanish Glass and Ceramic Society and Editor-in-Chief of Bol. Soc. Esp. Ceram. Vidrio. He has conducted electron microscopy on ceramics, glasses and glass-ceramics and their raw materials, being author of seven monograph books and more than 170 papers in glass-ceramics and advanced ceramics. He was invited Professor at the Department of Materials Science and National Electron Microscopy Lab, University California, Berkeley, during 1984-85 working in zirconial/mullite composites. Since last 15 years, he is active in the vitrification and recycling of a wide range of residues, up to simulated radioactive industrial wastes. Recently, he was the past President of the Spanish Society of Scientists.

Some glasses and glass-ceramics obtained from Canary Islands basalt rocks (La Gomera Fuerteventura, Tenerife and El Hierro) have been obtained by controlled melting and recrystallization. The electrical measurements have been carried out under complex impedance at temperatures in the 250°C-700°C range. From these electrical determinations, it was possible to follow the evolution of original glasses with respect the nucleation and crystal growth process. The main crystalline phases were pyroxenes, feldspar (anorthite) and magnetite. The magnetite decorates the dendritic crystallization of pyroxenes and it is the responsible phase of the electrical conduction properties. The ratio between Fe2+-Fe3+ was related to the Fe2+/Fe total content in the final materials allowing to propose an electronic conduction model.

In this study, we have reported a strategy to visually analyze and quantify macroscale and mesoscale damage on a single layer S-2 glass epoxy composite laminate, which was clamped in a 8 inch diameter circular frame and impacted by a 0.22 caliber right circular cylindrical steel projectile at initial velocities ranging from 104 m/s to 472 m/s. High-resolution images were obtained at the point of impact and up to the edge of the circular frame using an 80MP camera. Each sample was inspected for four types of mesoscale damage, i.e., transverse-tow cracks, tow-tow delamination, 45° matrix cracks and punch shear. Scanning electron microscope (SEM) was used to analyze visualized damage for single fibers at the center of the impact site while the developed MATLAB program was utilized to translate the image data into a digital damage map whereby the output of color intensity correlated with the quantity and type of material damage. Digital maps generated from the analyzed specimens revealed that the common damage in all samples were transverse-tow matrix cracks and tow-tow delamination.

Seungyoung So is an Associate Professor in the Department of Architectural Engineering and Head of Research Center of Industrial Technology at Chonbuk National University, South Korea. His research interests include the hydration gas of concrete and development of clean concrete.

The industrial and economic growth witnessed in recent decades has brought with it an increase in the generation of different types of waste (urban, industrial, construction, etc.) despite the waste management policies which have been adopted nationally and internationally. Recycling industrial waste not only brings huge economic benefits but also greatly helps the distribution of resources in the country. When waste material is managed correctly it can be converted into a resource which contributes to savings in raw materials, conservation of natural resources and complies with strategies for sustainable development. Ceramic goods are produced from natural materials containing a high proportion of clay minerals. And pottery can be used as an active additive thanks to their pozzolanic properties, or as recycled aggregate in the manufacture of mortars and concrete. This research studied the effect of grinding waste hygienic pottery proportions on binder in cement mortar. Experiments were conducted to determine the optimal replacement content and particle type to ensure that the quality of concrete products is maintained. The results indicate that the use of grinding waste pottery powder as an admixture for cement mortar was efficient in increasing compressive strength, workability and in reducing alkali silica reaction expansion due to the increased amount of calcium silicate hydrates created by pozzolanic reaction.
