Objective(s): This study was performed aiming to investigate the effect of particle engineering via spray drying of hydroalcoholic solution on solid states and physico-mechanical properties of acetaminophen. Materials and Methods: Spray drying of hydroalcoholic solution (25% v/v ethanol/water) of acetaminophen (5% w/v) in the presence of small amounts of polyninylpyrrolidone K30 (PVP) (0, 1...
In order to improve local therapeutic techniques for the massively burnt patients and to minimize the pain associated with dressing change, the concept of topical film was utilized to formulate a topical antimicrobial spray. The commonly used topical antimicrobial silver sulfadiazine spray was formulated as a new drug delivery system. The release of therapeutic agents in vitro from medicated sp...
Lipase is used in the production of foods, flavor enhancers, detergents, cosmetics and pharmaceuticals. A common impediment to the production of commercial enzymes is their low-stability aqueous solutions. In this study, the downstream process was investigated to obtain a stable spray-dried lipase powder of Yarrowia lipolytica. The enzyme solution samples were supplemented with different concen...
روش ها مختلفی برای خشک کردن موادی که بصورت محلول، تعلیق و یا خمیری می باشند وجود دارد یکی از روش ها خشک کردن پاششی است . در این روش خوراک تحت تاثیر انرژی اعمال شده بصورت اتمایز می شود کردن یعنی شکست و خردکردن توده خوراک به هزاران قطره ریز که بصورت دیده خواهد شد و انرژی لازم برای این امر از طریق گریز از مرکز، فشار، جنبش و یا صورت تامین می گردد. اگر انرژی بکار برده شده بصورت گریز از مرکز باشد، ات...

Background and aims: Nano-fibrous mats are one of the unique nonwoven materials that have been recently carried out in nanofiltration industry. The aim of this study was to synthesize nano-fibrous path mats using electrospining method following by determination of their efficiency for nanoaerosols removal. Methods: The efficiency and pressure drop of nano-fibrous mats was measured using nano-...
Electro-osmosis in clayey soils and sediments, for purposes of clay consolidation, dewatering, or cleanup, and electro injection in porous media is widespread recent decades. It is experimentally found that the chemical properties of porous media especially PH change the characteristics of media. Electro-osmotic conductivity is a function of soil and grout material chemistry, altering with time...
In order to determine the most appropriate nutrient solution spraying interval and effects of light quality in the root zone on anthurium in aeroponic system, a split plot experiment, with completely randomized design, was carried out in a greenhouse located in the city of Karaj, Iran. In this study, time between the sprays was the main plot and consisted of two levels (2 minutes spray and 30 m...
