This composite comprises of three phases, namely the primary Mg2Si phase, which is formed during the pseudo-eutectic transformation at the time of solidification engulfed by the matrix (α-Al) and the binary eutectic (Al-Mg2Si) phase. Microstructure evaluation and the mechanical properties of these composites has been investigated. It is observed that the change Mg2Si concentration has a great impression not only on the morphology and volume fraction but also in the hardness of all the phases that exist. The size and volume percentage of Mg2Si particle increases with the increase in Mg2Si concentration. Bulk hardness also increases with higher Mg2Si concentration. The micro hardness of the reinforcement (primary Mg2Si) particle decreased slightly with the increase in the Mg2Si concentration due to the less compact particle. On the contrary, the micro hardness of the other phases showed a gradual rise with the rise in Mg2Si concentration. The higher values of Quality Index, % elongation, ultimate tensile strength and toughness are achieved in the samples where the Mg2Si concentration is nearer to the pseudo-eutectic (13.9 wt. %) region. The yield strength, firstly shows a rising trend up to 25 wt. % Mg2Si and then decreases at 30 wt. % Mg2Si concentration.In this investigation, the hypereutectic in-situ Al-X wt. %Mg2Si (X=15, 20, 25 and 30) composites have been developed through gravity casting technique with the use of commercially pure Al, Si and Mg metals.

The samples were analysed using structural, surface and optical characterisation techniques. The structural analysis confirms the high crystalline nature of the samples along with its nanoscale size distribution. The titania samples synthesised with ethanol and propanol solvents exhibit mixed phase and the sample synthesized with butanol solvent showed pure anatase phase which agrees with the earlier reports revealing the role of length of the carbon chain of the solvent on phase transformation. The surface characterization reveals the formation of nano agglomerates in all the cases. Photoluminescence analyses of the samples were also carried out to identify the trap levels in the samples. The photocatalytic activities of the samples were performed under U-V irradiation with the probe pollutant methylene blue. All the three samples showed good photocatalytic performance compared to the commercial photocatalyst Degussa P25. The titania sample synthesized using ethanol solvent showed superior photocatalytic activity compared to other samples. The superior photocatalytic performance of the ethanol based titania sample maybe attributed to the efficient separation of the charge carrier at the anatase-rutile nano heterojunction of the mixed phase titania along with high surface area.

However, the starch based edible films produced from native starch exhibit poor water resistance and poor mechanical strength. Incorporation of nanomaterials in starch films is considered as an effective method in recent times in order to improve the mechanical and barrier properties. Present investigation focused on the effects of nanocellulose on the film properties of edible films produced from different starch sources, such as, maize starch, rice starch, wheat starch and potato starch. The starch edible films were solution cast by adding 5g/100 ml water, 30 wt% of solution and varying concentrations of nanocellulose (0%, 2%, 5%, 10% & 15% of solution). Water vapor transmission rate (WVTR), mechanical strength (tensile strength, Young’s modulus and percentage of elongation) and film color were determined for the films. The results showed that the addition of nanocellulose had improved the film properties in all the cases, and it could be used as a promising choice for food packaging applications.

Images are segmented into sub interrogation domain and cross correlation of images are evaluated by Fast Fourier Transform method. From the captured images, particle displacement is calculated and then magnitude of the velocity of micron size seeds in the plane is estimated. This technique is most suitable for high density concentration of seeded particles. Laser speckle velocimetry has wide range of pulse separation time and reduction of noise in the estimation of fluid velocity without directional ambiguity.","PeriodicalId":20725,"journal":{"name":"PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS: ICAM 2019","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88151343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
