pure and antimony doped sno2 thin films have been prepared by the sol-gel dip coating technique on glass substrate using starting material sncl2.2h2o as a host and sbcl3 as a dopant. our experimental results revealed that, the quality of the coated films on the glass depends on process parameters. the effect of annealing temperature, dipping numbers and the dopant concentration on the structura...

ZnO nanorods were prepared using dimethylamine (DMA) controlled Sol-Gel process. Dimethylamine was added as an additive to control the sol-gel process for growing ZnO nanorods. DMA would exhibit stabilizing effect, promote dissolution of precursor and control the rate of sol-gel reactions because of its basic nature and significant miscibility. The Structural and microstructural properties of t...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...

سدیم آلژینات (alg ) یک نوع پلیمر طبیعی غیر سمی ، همچنین زیست سازگار و تخریب پذیر میباشد. پلی وینیل الکل (pva ) نیز از پلیمر های سنتزی و زیست سازگار است که خواص مکانیکی قابل توجهی دارد به همین دلیل از pva و alg در مهندس بافت و ساخت داربست های زیست تخریب پذیر استفاده ی فراوانی می شود. از طرفی ژلاتین (gel) یکی از زیر شاخه های کلاژن می باشد که سهم عمده ای در ساختار شبکه خارج سلولی دارد و می تواند ...
