The purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. Casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. The size of the nano-emulsion and the pH of nano-emulsion were characterized. Ultrasound has been used for preparing emulsion by 24 KHz intensity for 120 seconds. Prepared nano-emulsion was investigated by pa...

Cellulose has a complex, multi-level supermolecular architecture. This natural polymer is built from superfine fibrils having diameters in the nano scale, and each such nanofibril contains ordered nanocrystallites and low-ordered nano-domains. In this review, the nano-structure of cellulose and its influence on various properties of the polymer is discussed. In particular, the ability of nano-s...

Nano-cellulose materials are widely believed to have the potential to push polymer mechanical properties. The cotton cellulose was dissolved in ionic liquid (1-butyl-3-methylimidazolium chloride ([Bmim]Cl)), and then was isolated by high pressure homogenization in a homogeneous media. The nano-cellulose was obtained at 80 MPa for 30 cycles. The geometry and microstructure of the cellulose nano-...

Nano erythrocyte ghosts have recently been used as drug carriers of water-soluble APIs due to inherit biological characteristics of good compatibility, low toxicity, and small side-effect. In this study, we developed a novel drug delivery system based on nano erythrocyte ghosts (STS-Nano-RBCs) to transport Sodium Tanshinone IIA sulfonate (STS) for intravenous use in rat. STS-Nano-RBCs were prep...

Belite cement was prepared using nano-silicas extracted from three different agricultural wastes – black rice husk ash (BRHA), bagasse (BA), and palm oil fuel (POFA) which were reacted at 1200 − 1400 °C with CaC2 residue as calcium source. The product compared that CaCO3. Nano-silica BRHA of very fine particle size (surface area 312.4 m2/g V/S ratio 0.35 × 106 cm) being highly reactive, forms β...

Over the past few years, the synthesis and characterization of nanocrystals of materials have become an area of intense research activity. MnCO3 (Manganese Carbonate) is a well known semi conducting material and is highly useful in electronic and optical devices. In the present study, we have made an attempt to prepare MnCO3 (with two different ratios of preparation) with simple domestic microw...

Electrocatalytic materials for oxygen reduction reaction, currently dominated by platinum/carbon catalyst is marred by drawbacks such as use of copious amount of Pt and use of "non-green" sacrificial reducing agent (SRA) during its synthesis. A single stroke remedy for these two problems has been achieved through an in-situ aqueous photoreduction void of even trace amounts of SRA with an enhanc...
