The reactivity of the protonated and hydroxylated sphalerite (1 1 0) surface with xanthate was simulated using the density functional theory (DFT). The difference between the energy of the lowest unoccupied molecular orbital of the sphalerite surface and the energy of the highest occupied molecular orbital of xanthate ( was used to compare the reaction capability of xanthate with fresh and fun...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Introduction : Introduction: Gonadogenesis is a complex developmental process which is regulated by molecular interactions such as cell surface and extracellular matrix (ECM) Glycoconjugates terminal sugars. The aim of this study was to determine Glycoconjugates terminal sugars expressions and changes during Gonadogenesis in Rat using Lectin histochemical technique. Methods : To determine o...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
introduction: as monoclonal antibodies are potential tools for characterization of soluble or cellular surface antigens, use of these proteins has always been considered in infertility and reproduction research. therefore, in this study, monoclonal antibodies against human sperm surface antigens were produced. material and methods: to produce specific clones against human sperm surface antigens...

Background and purpose : Despite the impressive progress in diagnosis and treatment of breast cancer, due to late diagnosis and metastasis to lymph nodes, it is still the leading cause of mortality in women. New studies showed a few changes in cell surface glycoconjugate in a few organs in process of neoplasia. The aim of the present study was to recognize Gal/GalNac in cell surface glycocon...
