مزوپروس های سیلیکاتی بعنوان یکی از چهار اکتشاف مهم در علم مواد و حالت جامد در دهه گذشته بشمار می روند. این مواد دارای حفراتی با اندازه 2 تا 50 نانومتر می باشند.این مواد حتی می توانند بعنوان کاتالیزورهای ردوکس عمل کنند. گسترش کاربرد این مواد از قبیل کاتالیزور و محیط جذب در زمینه های جدید از قبیل اپتیک و الکترونیک بسیار حائز اهمیت است.برجسته ترین عضو این گروه، mcm-41 است که دارای ساختار هگزاگونال...
Abstract With smart speakers diffusing into society, artificial intelligence is moving from the imaginative reservoirs of dystopian storytelling vernacular living. How do users perceive communication with it? Are Alexa and Siri considered simple devices, sentient assistants, or even friends? Based on nine qualitative interviews former speaker in Germany, this study analyzes use related personal...
Nucleolar organising regions (NOR) are part of the nucleolus, containing argyrophilic proteins (nucleoclin/C23, nucleophosmin/B23). They are identified by silver staining at low pH. The method also reveals osteocyte canaliculi and cement lines and granules in the cytoplasm of kidney cells in locations that mimic osteopontin distribution. Human bone and kidney sections, benign and lymphomatous p...
Members of the T cell immunoglobulinand mucin-domain-containing molecule (TIM) family have roles in T cell-mediated immune responses. TIM-1 and TIM-2 are predominantly expressed on Th2 cells, whereas TIM-3 is preferentially expressed on Th1 and Th17 cells. We found that TIM-1 and TIM-3, but neither TIM-2 nor TIM-4, were constitutively expressed on mouse peritoneal mast cells and bone-marrow-der...
Dendritic cells (DC) undergo complex developmental changes during maturation. The MHC class II (MHC II) molecules of immature DC accumulate in intracellular compartments, but are expressed at high levels on the plasma membrane upon DC maturation. It has been proposed that the cysteine protease inhibitor cystatin C (CyC) plays a pivotal role in the control of this process by regulating the activ...
