Formation of intermetallic phases at the metal-silicon interfaces

Reduction of surgery-induced peritoneal adhesions by continuous release of streptokinase from a drug delivery system Yagmurlu, A; Barlas, M; Gursel, I; Gokcora, IH (S. Karger AG, 2003-01-01) Postoperative abdominal adhesions may lead to intestinal obstruction and infertility. The effect of continuous release of streptokinase to the peritoneal cavity on postoperative adhesions was examined under experimental conditions. Peritoneal adhesions were induced in rats and the animals were further treated by intraperitoneal administration of streptokinase solution, polyhydroxy-butyrate-co-hydroxyvalerate (PHBV) membrane alone and streptokinase loaded PHBV membrane and compared to sham operated and untre...
Synthesis of 2,3-disubstituted thiophenes from ketoalkynes Vatansever, Erol Can; Balcı, Metin; Department of Chemistry (2013) Synthesis of thiophene containing compounds are of particular interest in synthetic organic chemistry. Besides the importance for synthetic organic chemistry, thiophene derivatives are used in applied research such as drug synthesis and study of functional materials. In this thesis, a new methodology for developing of 2,3-disubstituted thiophenes was developed. This methodology utilizes readily available compounds in a two-step synthesis to provide a facile access to the 2,3-disubstituted thiophenes. In the...
Synthesis of highly substituted alkynylpyridines and development of new methodologies for the synthesis of 1,4-oxazepines, 1,4-thiazepines and 5-methylpyridines / Kelgökmen, Yılmaz; Zora, Metin; Department of Chemistry (2018) Convenient syntheses of pyridines, 1,4-oxazepines and 1,4-thiazepines have become an important research area among organic chemists since they constitute scaffolds of many medicinal substances. Recently, N-propargylic β-enaminones have been widely used for the facile synthesis of potent biologically active heterocycles. Many research groups have focused on the proper synthesis of various heterocycles by using N-propargylic β-enaminones. One of the such recent reports using these precursors is the formation ...
Synthesis of anthracene-based macrocycle for detection of explosives Yılmaz, Tuğçe; Özçubukçu, Salih; Department of Chemistry (2019) Development of fluorescent sensors for detection of explosives become very interesting area for researchers. Picric acid is an important member of nitro-aromatic compounds which is also a powerful explosive. Fluorescent sensors are one of the essential way to detect picric acid, since they have many advantages, such as high sensitivity, simple instrumentation, and quick response. Cyclophanes are molecules that their cyclic structure makes them very promising candidate for molecular recognition. Anthracene-b...
Synthesis and characterization of conducting copolymers of thiophene-3-yl acetic acid cholesteryl ester with pyrrole Çırpan, Ali; Toppare, Levent Kamil; YAGCI, Y (2002-05-01) A new polythiophene containing a cholesteryl side chain in the beta-position was chemically polymerised in nitromethane/carbontetrachloride using FeCl3 as the oxidizing agent. Polymerisation was also achieved by constant current electrolysis in dichloromethane. Subsequently, conducting copolymers of thiophene-3-yl acetic acid cholesteryl ester (CM), PCM1 (obtained from chemical polymerisation method) and PCM4 (obtained from constant current electrolysis) with pyrrole were synthesized using p-toluene sulfoni...
