Electrospun nanofibers present a new and rapidly growing research area due to their pronounced micro and nano characteristics associated with high surface area to volume ratio. Poly(styrene-co-acrylamide) and polystyrene polymers were synthesized by boiling temperature soap free emulsion polymerization in aqueous medium with potassium peroxosulphate as the initiator. The resulting polymers were...
The motivation of this work is to create luminescent rare earth/polymer films with outstanding water-resistance and superhydrophobicity. Specifically, the emulsion polymerization of styrene leads to core particles. Then core-shell-structured polymer nanoparticles are synthesized by copolymerization of styrene and acrylic acid on the core surface. The coordination reaction between carboxylic gro...
A rollable and all-solid-state textile lithium battery based on fabric matrix and polymer electrolyte that allows flexibility and fast-charging capability is reported. When immerged into poly(3,4-ethylenedioxythiophene) (PEDOT) nano-emulsion inks, an insulating fabric is converted into a conductive battery electrode for a fully solid state lithium battery with the highest specific energy capaci...

BACKGROUND Nutritional and topical antioxidants and immuno-modulant compounds play a key role in maintaining healthy skin. However, little is known about the combined effects antioxidant cosmeceuticals and nutricosmetics can have on the appearance of aging skin. OBJECTIVE The clinical trial was designed to study the combined effects on skin hydration, superficial lipids, elasticity, peroxidat...
در سالهای اخیر تلاش زیادی برای سنتز کمپلکس های سوپرامولکول و پلیمرهای کوئوردیناسیونی بر مبنای لیگاندهای آلی چند دندانه شده است. این مواد به دلیل داشتن خواص منحصر به فرد، کاربردهای زیادی در صنعت دارند. سنتز پلیمرهای کوئوردیناسیونی جدید از سرب(ii) در ابعاد بالک(توده) و نانو با استفاده از روش گرادیان دمایی و به روش شاخه جانبی صورت گرفته و با روش طیف سنجی ir و پایداری گرمایی آن ها توسط آنالیزهای وز...
Psoriasis is a lifelong condition which is caused by the negative signals produced by immune system, which leads to hyper proliferation and other inflammatory reactions on the skin. In this case, keratinocytes which are the outermost layer of skin possess shortened life cycle and results in the alteration of desquamation process where the cytokines will come out through lesions of affected pati...
The use of nano-encapsulated resveratrol (RSV) in self-micro-emulsified drug delivery systems (SMEDDS) formulations was investigated. Self-emulsifying grading tests were used to establish the optimal ratio of oil, surfactant, and co-surfactant. The optimized system was further investigated for the droplet size and zeta potential at the different medium pH values by a Malvern Zetasizer and trans...
The low density lipoprotein (LDL) receptor has been shown to be upregulated in GBM tumor cells and is therefore a potential molecular target for the delivery of therapeutic agents. A synthetic nano-LDL (nLDL) particle was developed and tested to determine its utility as a drug delivery vehicle targeted to GBM tumors. nLDL particles were constructed by combining a synthetic peptide containing a ...
PURPOSE Azithromycin (AZI) is a new macrolide antibiotic with a better activity against intracellular gram negative bacteria in comparison with Erythromycin. The purpose of this research was to prepare AZI nanoparticles (NPs) using PLGA polymer and to compare the effectiveness of prepared nanoparticles with untreated AZI solution. METHODS AZI NPs were prepared by Modified Quasi-Emulsion Solve...
