A simple, sensitive, rapid, precise and economical reverse phase HPLC method has been developed for the estimation of valsartan from pharmaceutical dosage forms. The was carried out using Chromatographic conditions were established by employing a C18 analytical phenomenal (Kinetex) column (5micron -C18, 250x4.6mm) with mobile phosphate buffer (PH 3.5) acetonitrile in 60:40 ratio. sample injecte...

in this study the effect of basil seed gum (bsg) concentration (0%, 0.005%, 0.02%, 0.08%, 0.15% and 0.3% w/w) on the stability, particle size distribution and rheological properties of o/w emulsion stabilized by whey protein isolate (0.5% w/w) was investigated at neutral ph. the emulsion prepared by using a sonicator with a nominal power output of 150 w and an operating frequency of 20 khz. son...

In this article, the synthesis of magnetite nanostructures was successfully carried out by sonochemical process. method, stoichiometric amount iron chlorides (FeCl3.6H2O and FeCl2.4H2O), ammonia (NH3) polyvinylpyrolidone (PVP) were used to synthesize pure Fe3O4 nanoparticles. The effect initial sonication power ultrasonic device on size morphology final products as one effective parameters inve...

Lowering Intraocular pressure (IOP) is a main therapeutic objective in glaucoma patients because IOP an important risk factor for progression. The of this work was to formulate and evaluate, vitro vivo, stable effective Solid Oil (S/O) topical formulation the antiglaucoma drug, timolol maleate (TM). S/O dispersions were prepared by emulsification aqueous TM solutions cyclohexane using different...

Abstract The newest method to maintain better bioavailability of antioxidant compounds in the human digestive process is encapsulation using liposomes. liposomes used were lecithin from soybean seeds and L-α-Phosphatidylcholine. Furthermore, curcumin β-carotene encapsulated soy SC-CO2 with 100% ethanol, aquadest 50% v/v ethanol at 50°C, 60°C, 70°C pressure 15 MPa, 20 MPa 25 by ultrasonication f...

The degradation of poly (vinyl pyrrolidone) (PVP) by means of ultrasound irradiation and itscombination with heterogenous photocatalysis (TiO2 nanoparticles) was investigated. Emphasiswas given on the effect of additive on degradation rate constants. 24 kHz of ultrasoundirradiation was provided by a sonicator, while an ultraviolet source of 30 W was used for UVirradiation. To increase the effic...

In this study, carbon nano fibers (CNFs) were mixed into epoxy resin through a magnetic stirrer and again mixed using ultra sonicator. Using hand layup technique, biaxial braided fiber composites were prepared with unfilled, 0.2, 0.5 and 1 wt% CNF. Tensile test and shear test was performed to identify the tensile strength and shear strength of the composites. Fractured surface of the tensile sp...

The work aims to prepare and characterize polyester nanoclay nanocomposite (PNNCs) with various weight percentages (0, 2, 4). Nanoclay resin are blended using a mechanical stirrer followed by sonicator. blend is molded as specimens per ASTM standards. addition of improved tensile strength 12% 16% flexural 4% 10%. After 60 days soaking in, the retention rate pure PE, 2PNNC, 4PNNC 84.9%, 89.8%, 9...

The core objective of this analysis is to implement a combination alkaline (NaOH) and sonication pretreatment techniques produce energy-efficient biohydrogen from the marine macroalgae Chaetomorpha antennina. Anaerobic fermentation was implemented in control, sonic solubilization (SS) alkali (SAS) for 15 days. In production 40 mL H2/gCOD obtained. sonicator intensities varied 10% 90% period 1 h...
