Mechanistic Insights into the Reaction of N-Propargylated Pyrrole- and Indole-Carbaldehyde with Ammonia, Alkyl Amines, and Branched Amines: A Synthetic and Theoretical Investigation Sari, Ozlem; Seybek, Ali Fatih; Kaya, Serap; Menges, Nurettin; ERDEM, SAFİYE; BALCI, METİN (Wiley, 2019-09-01) The reaction of pyrrole- and indole-carbaldehydes having a propargyl group attached to the nitrogen atom with various amines was studied. The reaction with ammonia formed pyrrolo[1,2-a]pyrazine and pyrazino[1,2-a]indole wh...
Recovery of Scandium by Crystallization Techniques Peters, Edward Michael; Kaya, Serap; Dittrich, Carsten; Forsberg, Kerstin (2019-03-01) Bauxite residues, i.e., red mud, can be processed to recover various valuable end products, while reducing the environmental impact of the waste. Scandium is one of the valuable elements in bauxite residues. It is possible...
Scandium Recovery from an Ammonium Fluoride Strip Liquor by Anti-Solvent Crystallization Kaya, Serap; Forsberg, Kerstin; Dittrich, Carsten; Stopic, Srecko; Friedrich, Bernd (2018-10-01) In this study, the crystallization of scandium from ammonium fluoride strip liquor, obtained by solvent extraction, was investigated using an anti-solvent crystallization technique. Acetone, ethanol, methanol and isopropan...
Solvent extraction behaviour of scandium from lateritic nickel-cobalt ores using different organic reagents Ferizoglu, Ece; Kaya, Serap; Topkaya, Yavuz Ali (2018-04-01) Scandium is one of the most important and strategic metals that can be recovered as a by-product from lateritic nickel-cobalt ores. In this research, different extractants were investigated to extract scandium from sulphat...
Buried and Surface Mine Detection From Thermal Image Time Series Kaya, Serap; Leloğlu, Uğur Murat (2017-10-01) Millions of buried and surface landmines throughout the world will continue to kill and injure people for many decades. Reliable landmine detection systems, especially those that do not require that an operator enters a mi...
A new synthon for the synthesis of aminoinositol derivatives Cokol, Nalan Korkmaz; Kaya, Serap; BALCI, METİN (Elsevier BV, 2017-07-12) The regio- and stereoselective synthesis of a new synthon, trans-3,8-dioxatricyclo[3.2.1.0(2,4)]octane-6,7-diamine, from 7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate is reported. Transformation of the acid functionaliti...
On the stability at all times of linearly extrapolated BDF2 timestepping for multiphysics incompressible flow problems AKBAŞ, MERAL; Kaya, Serap; Kaya Merdan, Songül (2017-07-01) We prove long-time stability of linearly extrapolated BDF2 (BDF2LE) timestepping methods, together with finite element spatial discretizations, for incompressible Navier-Stokes equations (NSE) and related multiphysics prob...
Solvent extraction of scandium from lateritic nickel- cobalt ores using different organic reagents Ferizoglu, Ece; Kaya, Serap; Topkaya, Yavuz Ali (2016-09-28) Scandium is the most important and strategic metal that can be recovered as a by-product from lateritic nickel-cobalt ores. In this research, different extractants were investigated in order to extract scandium from a sulf...
Gold-Catalyzed Oxime-Oxime Rearrangement Guven, Sinem; Ozer, Merve Sinem; Kaya, Serap; Menges, Nurettin; BALCI, METİN (2015-06-05) The gold-catalyzed reaction of pyrrole and indole oximes having a propargyl group attached to the nitrogen atom was studied. The selective 6-endo-dig mode of cyclization was observed for the terminal alkynes giving rise to...
Morphology and magnetic properties of barium hexaferrite ceramics synthesized in x wt% NaCl-(100-x) wt% KCL molten salts Aydogan, Eda; Kaya, Serap; Dericioğlu, Arcan Fehmi (Elsevier BV, 2014-01-01) Micron size barium hexaferrite (BaFe12O19) platelets were prepared by the molten-salt synthesis method in various weight proportions of NaCl-KCl salt mixtures as a liquid medium. The effect of molten salt composition-x wt%...
