Laser advancement in coronary stent manufacture. Laser cutting is one of the key fabrication technologies applied to coronary stent manufacture. In the early development of laser stent cutting, the processes struggled with the cut quality issues., Manufacturing of stents have to focus on the stability and uniformity of cutting process to fulfill the stringent requirement of the stent devices. With the growth of laser technology, the emergence of ultra-short pulse lasers provides stable process and uniformity in the product quality. The ultra-short pulse laser cutting also improves the surface finish, tolerance and higher degree of process control which relates to cost improvement. The characteristics of long pulse (millisecond pulse) laser cutting and recent ultrafast (picosecond and femtosecond pulsed) laser microfabrication for stent manufacture are included. Different approaches/techniques to aid cut quality improvement are presented.

Industrially scaled metallurgical graphene manufacturing.The novelty of the presentation is the mechanism of graphene growth from the liquid phase on the bimetallic Cu-Ni substrates. It will describe stages of nucleation as well as graphene flakes growth and self-organizing of them which have been revealed and identified. Additionally, the effect of zone refining has been observed and confirmed. The mechanism of the studied phenomena and process organization will be presented, together with industrially scaled equipment and technology for metallurgical graphene manufacturing. It enables the growth of quasi-mono crystalline and low defected graphene on large substrates of area up to ca. 1 m2. Furthermore, the selected issues of metallurgical graphene quality assessment and graphene transfer will be discussed, as well as several applications examples will be shown.

Metallic Cultural Heritage artefacts: corrosion mechanisms and prevention strategies. Cultural Heritage assets deterioration is the result of several causes, environmental, as light, temperature, humidity, gaseous pollutants, or biological. Cultural Heritage assets deterioration is the result of several causes, environmental, as light, temperature, humidity, gaseous pollutants, or biological, as biofilms growing on the surface. The negative impact of air pollution becomes more important at higher values of temperature and relative humidity, thus it is expected to increase dramatically with the on-going climate change, both in outdoor and indoor conditions, consequently multipurpose monitoring and control systems become more and more important for developing mitigation solutions. Conservation of metals needs of a complex multi-step approach, which requires a specific interaction with the object in order to identify degradation agents and mechanisms and to establish their chemical-physical stability via tailored conservation treatments. The challenge is the design and development of preventive conservation tools for predicting the onset of heritage degradation, preventing disasters and damages into the historical and archaeological sites, defining protocols for the long-term safeguard of Cultural Heritage healthy conditions. Scientific and technological solutions for the safeguard of metallic artifacts, developed by the multidisciplinary group of the Politecnico di Torino, are illustrated. They cover a wide panorama of applications, from environmental sensors, smart buttons, to conservation materials and diagnostic tools, as portable instruments for impedance measurements. As a matter of facts, the conservation of metals needs of a complex multi-step approach, which requires a specific interaction with the object in order to identify degradation agents and mechanisms and to establish their chemical-physical stability via tailored conservation treatments. A highly sensitive and innovative methodology for evaluating the safety level of the museum indoor areas, and more specifically of the interior of the showcases, with respect to the metallic artefacts is under test, from years, in several museums and historical sites, as the Stibbert Museum in Florence, the Egyptian Museum of Cairo, the Villa della Regina in Torino, the Puente de Boyacà in Colombia, the National Museum of Colombia in Bogotà. The methodology is based on the use of an innovative smart sensors network for the continuous monitoring of temperature and relative humidity and of copper, silver, iron reference samples, the chemical-physical characterization of the artefacts corrosion products with the ultimate goal of developing tailored preventive conservation strategies.

Chloride diffusion in concrete - mechanism, experiment and simulation. Chloride induced reinforcing steel corrosion is a worldwide problem. In order to prevent steel from corrosion one has to know how chlorides transport in concrete and what factors affect the chloride transportation in concrete. In his talk, Prof Li will show the recent progress in the research related to chloride transport in various different concrete materials. Contents include the theoretical models to understand the mechanism of chloride diffusion, the experimental methods to obtain the diffusion and migration coefficients of chloride ions, and the micro- and macro-models of numerical simulations to investigate the factors influence chloride diffusion in concrete.

Rice husk ash-GGBS based geopolymer composites reinforced with various steel fibers: strength properties and thermal behavior. Due to the increasing environmental impacts, the construction industry is witnessing a rising trend towards using green and waste materials. In the light of such event, the researchers recently tended to conduct their studies depending on the fact that cementitious materials are more hazardous to the environment. Geopolymers, as one of the most successive potential alternatives, possess comparable performance regarding strength properties, durability, long term behavior and other aspects. In this paper, an experimental investigation is performed to inspect the performance of two widely used materials in the geopolymeric matrix, namely Ground Granulated Blast Furnace Slag (GGBS) and Rice Husk Ash (RHA). The effects of partial replacement of the aforementioned materials and incorporating various steel fibers within the matrix were studied. Tests of strength properties and behavior under the effect of elevated temperature. In general, using the designated materials were found to be beneficial in producing a matrix with better performance with respect to the ordinary cementitious composites in terms of the investigated properties. Also, the results revealed the fact that using rice husk ash was responsible for increasing the compressive strength of the fabricated samples while the embedded fibers improved the flexural behavior of the resulted matrix.

Double Durability Performance of Geopolymer Composites. Although cement is the main material used in concrete production, production of more environmental friendly materials has been investigated due to high energy consumption and greenhouse gas emissions during the production process. In this study, more environmentalist geopolymers were produced instead of traditional Portland cement production. The generated geopolymer composites were exposed to a high temperature effect after the freezing thaw effect. The results of weight loss, ultrasonic pulse velocity, compressive and flexural strengths were examined at the end of the tests. Results have shown that geopolymer composites are resistant to durability conditions.
