The production of steel of desired composition is realized as a result of bringing some of the elements to the desired amounts after a series of chemical reactions occurring at different velocities between the elements or compounds at high temperatures and adding alloy materials for the other elements needed in the composition. The steel production process in an electric arc furnace can be defined in the following order: scrap charge, melting, oxidation, reduction, alloying, deoxidization, casting, and preparation of the furnace. In this study, a mass analysis is accomplished for an electric arc furnace at a steel company in Turkey. . . . In order to make the mass balance, firstly all materials that are entering the system are calculated on a chemical component basis. The necessary information was provided from an iron and steel producing company. The results of the mass analysis are presented at the end of the study. © 2012 Springer Science+Business Media, Inc Daha fazlası Daha az

As the fundamental understanding of metal-light interactions gains solid grounds, further research has been devoted to construct novel structures that take full advantage of such unique interactions, which is called plasmonics. In this report, the preparation of Au-Ag core-shell structures obtained by coating the Au surface with peptide and Raman reporter molecule and depositing an Ag layer on it is reported. The prepared Au-Ag NPs are tested for their surface-enhanced Raman scattering (SERS) performance. The negatively charged peptides with three different lengths, which are 3 (P1), 15 (P2), and 21 (P3) amino acid long, were chemic . . .ally attached to 13 nm AuNPs along with Raman reporter molecule, carboxytetramethylrhodamine, and these modified AuNPs were coated with three different shell thickness of Ag metal. The prepared Au-Ag NPs were tested for their SERS performance and found that the Au-Ag NPs prepared with P2 and thickest shell performs best as SERS label. © 2011 Springer Science+Business Media, LLC Daha fazlası Daha az
