in this research, an efficient synthesis toward 2-(2-((4-methoxybenzoyl)imino)-4-(4-methoxyphenyl)thiazol-3(2h)-yl)-2-phenylacetic acid via a three-component tandem reaction using aroylisothiocyanate, phenyl glycine, and 4-methoxyphenacyl bromide in an ionic liquid (il) has been described. 1-methyl-3-pentylimidazolium bromide (il) has been employed as a recyclable green solvent. the work-up pro...

objective(s): short tandem repeat (str) loci are the most informative dna genetic markers for attempting to individualize biological material for application in paternity and forensic cases. materials and methods: blood samples were collected and the total genomic dna was extracted. the dna samples were used for genotyping vwa and tpox str loci using pcr and polyacrylamide gel electrophoresis. ...

∗ Undergraduate Research Participants Abstract Argonne’s ATLAS (Argonne Tandem-Linac Accelerator System) control system comprises two separate database concepts. The first is the distributed real-time database structure provided by the commercial product Vsystem [1]. The second is a more static relational database archiving system designed by ATLAS personnel using Oracle Rdb [2] and Corel Parad...

Hydrogenated microcrystalline silicon (μc-Si:H) as deposited by PECVD at low temperatures (around 200°C) can be used to fabricate stable pin-type solar cells with conversion efficiencies over 8 %. The variety of growth forms and microstructural patterns observed for different deposition conditions is described; the requirements to be met by layers for use in μc-Si:H solar cells are listed. A pa...

Three possible causes responsible for the large genome size of a cyanobacterium Anabaena sp. PCC7120 are investigated: 1) sequential tandem duplications of gene segments, genes or genomic segments, 2) horizontal gene transfers from other organisms, and 3) whole-genome duplication. We evaluated the frequency distribution of angles between paralog locations for the possibility 1), the fraction of...

Tandem solar cells consisting of amorphous and microcrystalline silicon junctions with the top junction nanopatterned as a two-dimensional photonic crystal are studied. Broadband light trapping, detailed electron/hole transport, and photocurrent matching modulation are considered. It is found that the absorptances of both junctions can be significantly increased by properly engineering the duty...
