عملکرد موفق دوده سیلیسی در بهبود قابل توجه خواص مکانیکی و دوام بتن باعث شده تا استفاده از مواد نانوسیلیسی در محصولات پایه سیمانی مورد توجه جدی محققین چه در سطح جهان و چه در داخل کشور قرار گیرد. خلوص نزدیک به 100 درصد مواد نانوسیلیسی در مقایسه با خلوص حدود 90 درصد دوده سیلیسی و همچنین سطح ویژه بالاتر این مواد که محدوده ای از 50 تا قریب به 1000 مترمربع برگرم را در بر میگیرد در مقایسه با سطح ویژه ...
Previous reports show ineffective transdermal delivery of ketorolac by nanostructured lipid carriers (NLCs). The aim of the present work was enhancement of transdermal delivery of ketorolac by another colloidal carriers, lipid nanocapsules (LNCs). LNCs were prepared by emulsification with phase transition method and mixed in a Carbomer 934P gel base with oleic acid or propylene glycol as penetr...
Abstract
 
 Background: Banyuwangi has the potential of diverse natural resources. One example plant that can be utilized is butterfly pea (Clitoria ternatea L.). The contents are phenolic acids, stilbenes (phytoalexins), flavanols, anthocyanins, flavonols and flavanones, polyphenols flavonoids. In this research, preparations were developed from extract into powder form to make it mor...
Hydrophobic grade fumed silicas are generally used in tabletting as lubricants. They are also found to retard the release of pharmaceutical actives. This is because of their hydrophobic nature, which gives good cohesive and adhesive properties. considering this point it was thought that they could be used as dry coating agents for solid dosages forms. The model drug selected for this work was p...
Breeding sturgeons in aquaculture is the only way to preserve them as a raw material for fish food products today. In this regard, not need development of commercial sturgeon breeding obvious, but also importance research aimed at studying and developing optimal modes industrial cultivation different species sturgeon. The aim work expand range compound feed sturgeons, expense unused reserves ex...
Mục tiêu: Nghiên cứu các điều kiện tối ưu cho quá trình chế cao phun sấy bưởi non với việc hóa hàm mục tiêu bằng phương pháp tiếp cận mong muốn. Đối tượng và pháp: 20 thử nghiệm được tiến hành để mô tả sự ảnh hưởng của nhiệt độ khí vào, lưu lượng khí, loại tỷ lệ giá mang đến sấy. Kết quả: Điều là vào 160 oC, 200 m3/h, maltodextrin – aerosil (2:1) 70 % so chất rắn trong cao. Khi đó, hiệu suất đạ...
Understanding the influence of storage time on the rheological properties polymeric fumed silica gels is very important in the field of composite polymer electrolytes. A rheological study of the aging process of Aerosil R805 suspension in Polypropylene Glycol Mw2000 has been carried out by means of steady and oscillatory experiments.
هدف در این پروژه بهبود راندمان جداسازی آنتی ژن سطحی هپاتیت ب از مخلوط پروتئینی به روش جذب سطحی می باشد که از نرم افزار طراحی آزمایشات ( تاگوچی ) استفاده می شود. در اینجا از چهار نوع جاذب معدنی مختلف با نام های تجاری a,b,c)) celite و aerosil استفاده می شود و به مقایسه راندمان جذب آنتی ژن بر روی این چهار جاذب پرداخته شده است. در فرایند جذب ، با تغییر و تنظیم شرایط محیطی، آنتی ژن سطحی هپاتیت ب بر ...
Objective: The aim of this study was to investigate the potential a liquisolid system improve dissolution rate and bioavailability nebivolol hydrochloride. Methods: Solubility determined in different nonvolatile solvents finalize best vehicle having maximum solubility. compacts were prepared using Fujicalin as carrier material, Aerosil 200 coating Polyethylene glycol 400 liquid vehicle, Croscar...
