The reaction of 3-mercaptopropylsilica (MPS) and chlorosulfonic acid in chloroform afforded silica bonded S-sulfonic acid (SBSSA), which was used as a catalyst for the room temperature synthesis of quinoxaline derivatives from 1,2-diamino compounds and 1,2-dicarbonyl compounds. The catalyst could be recycled and reused several times without any loss of(More)
Magnetic Fe(OH)3@Fe3O4 nanoparticles were successfully prepared and characterized. This magnetic nanocomposite was employed as an efficient, reusable, and environmentally benign heterogeneous catalyst for the direct amidation of alcohols with amine hydrochloride salts. Several derivatives of primary, secondary and tertiary amides were synthesized in(More)
A highly selective and sensitive colorimetric sensor for the determination of naproxen (NAP) based on the aggregation of the thiolated β-cyclodextrin (Tβ-CD) functionalized gold nanoparticles (Tβ-CD-Au NPs) in the presence of NAP and Zn2+is described. The hydrophobic end of NAP interacts with the immobilized Tβ-CD on the Au NPs and forms the complex of(More)
Die Identifikation von partikulären Prothesenmaterialbestandteilen in der histopathologischen Synovialitis- bzw. Periprothetischen-Membran-/Synovial-like-interface-membrane(SLIM)-Diagnostik besitzt zur Abklärung des Gelenkendoprothesenversagens einen wichtigen Stellenwert. Im histopathologischen Partikelalgorithmus werden Polyethylen(PE)-Partikel mit(More)
Die histopathologische Diagnostik von Gelenkendoprothesen-assoziierten Erkrankungen basiert mehrheitlich auf der histopathologischen Konsensusklassifikation von Synovialis/SLIM („synovial-like interface membrane“) und periprothetischen Geweben. Dementsprechend erfolgt eine Klassifikation in 7 Typen: Typ I – partikelinduziert, Typ II – bakterielle Infektion,(More)
