[ 1 ] - Detection of Polymer Brushes developed via Single Crystal Growth
Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...
[ 2 ] - بررسی اثر کاربید بور بر پخت و پایداری حرارتی رزین رزول
در این پژوهش اثر پرکننده کاربید بور (B4C) به میزان 1 درصد بر پایداری حرارتی رزین رزول مورد بررسی قرار گرفت. در مطالعه خواص حرارتی از آزمون‌‌های گرما وزن‌سنجی (TGA) جهت بررسی رفتار تخریب رزین و میزان زغال‌گذاری آن و آزمون گرما‌سنجی تفاضلی پویشی (DSC) جهت مطالعه رفتار پخت رزین و تاثیر کاربید بور بر گرمای واکنش پخت استفاده شده است. نتایج حاکی از آن است که با افزودن کاربید بور میزان زغال‌گذاری رزی...
[ 3 ] - Nanostructured Single Crystals Sandwiched between Ordered/Disordered Coily and Rod Brushes
Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...
[ 4 ] - Numerical Study on Parameters Affecting the Structure of Scaffolds Prepared by Freeze-Drying Method
Freeze-drying is one of the most used methods for preparing scaffolds and is very sensitive to the material and operational parameters such as nucleation temperature, thermal properties of the mold, cooling rate, set freezing point, and slurry height. In the present study, a Finite Element Method (FEM) based code was developed to investigate the effects of such parameters and to eventually ...
