[ 1 ] - Unsteady-state Computational Fluid Dynamics Modeling of Hydrogen Separation from H2/N2 Mixture

3D modeling of Pd/α-Al2O3 hollow fiber membrane by using computational fluid dynamic for hydrogen separation from H2/N2 mixture was considered in steady and unsteady states by using the concept of characteristic time. Characteristic time concept could help us to design and calculate surface to volume ratio and membrane thickness, and adjust the feed conditions. The contribution of resistance be...

[ 2 ] - Isothermal Melt Crystallization Kinetic Behavior of Poly (vinylidene fluoride)

Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...

[ 3 ] - Controlled Antibiotic Delivery by Gelatin Nanospheres: Optimization, Characterization and Antibacterial Evaluation

The present work focuses on preparation and characterization of erythromycin loaded gelatin nanoparticles through nanoprecipitation method. The procedure consists of the addition of the aqueous gelatin solution to the non-solvent phase containing Lutherol F127. Three different measures of cross-linker and polymer concentration were also examined, and the optimum concentration was found. The mor...

[ 4 ] - مروری بر کاربرد فناوری چاپ سه‌بعدی در سامانه‌های نوین دارورسانی

در فرایند چاپ سه‌بعدی، اجسام به‌کمک مدل دیجیتالی با قرارگیری لایه‌به‌لایه مواد روی هم ساخته می‌شوند. در سال‌های اخیر، کاربرد روش چاپ سه‌بعدی در ساخت فراورده‌های دارویی با قابلیت رهایش کنترل‌شده دارو مورد توجه قرار گرفته است. از مزایای این روش می‌توان به قابلیت ساخت اشکال دارویی سفارشی برای هر بیمار با شکل هندسی پیچیده همراه با بارگذاری هم‌زمان چند دارو و مواد افزودنی مختلف اشاره کرد. این فن برا...

[ 5 ] - Effect of Different Additives on Separation Performance of Flat Sheet PVDF Membrane Contactor

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

[ 6 ] - Synthesis and Study of Lidocaine Hydrochloride from Polymeric Film as a Wound Dressing

Introduction: Among various carrier materials capable of drug controlled-release, silica xerogels have been found to be noteworthy for loading and sustaining drug release. These silica xerogels were synthesized through sol-gel technology using Tetraethylortosilicate (TEOS) as a silica precursor. Methods: This study was an experimental basic research, which aimed to characterize the effect of a...
