17. Abstract This paper describes a method for determining the density of Al 2 O 3 nanocrystals entrained in an alumina-based matrix. The entrainment is intended to facilitate the coalescence of smaller particles into larger ones for subsequent sintering. The methodology for making the my stimulating Raman spectra over the range 250-4000 cm-1 is presented. The developed system is a simple to use, low cost, and rapid (short examination delay) instrument that can be used to easily determine the density of a manufactured material. The method is demonstrated using synthetic Al 2 O 3 materials, and the Al 2 O 3 densities determined by the proposed method are compared to those determined with the conventional technique of KBr density dilution. The developed method is validated by analyzing industrial grades of alumina of known density. Future plans and applications are discussed.

Abstract The fundamental challenges that limit the growth of biotechnological industries are the inability to scale up synthesis processes to a commercially viable scale, and the inability to meet the increasing need for superior quality and quantity of bioproducts. Biofuels are an excellent solution because they are clean, renewable, and environmentally friendly. Microalgae are considered as the most promising feedstock for producing biofuels due to their fast growth rate, high photosynthetic efficiency, and inexpensiveness. Previous reports have shown that single genes from unrelated species can be combined and allow the production of valuable biofuels. These reports have mainly concentrated on the improvement of algae cultivation. In this project it is proposed to construct algal biofuel-related crop plants of oil crops such as soybean and rapeseed. For this purpose, two strategies are followed. One is to convert the plants into nuclear expression vectors through homologous recombination using marker genes. These vectors could be delivered to the plants using Agrobacterium, and transform the plants successfully. The other is to transform these plants into complex mixture by the transformation of a mixture strain with oil crops and algae. The mixability of the transformants in the complex mixture would be detected using a haploid tagged system using a binary selection marker. The detection methods will be carried out through a combination of hard agarose gel electrophoresis, Southern blotting, polymerase chain reaction, and multiplex PCR. d2c66b5586
