NANOCARRIERS AS PROMISING NOVEL SYSTEMS FOR CONTROLLED DELIVERY OF DICLOFENAC SODIUM [N.B: Authors' details blinded by Pro Journals for Review] ABSTRACT The formulation and evaluation of Diclofenac sodium from liposomes, niosomes and nanoemulsion are analyzed. The release profiles of Diclofenac sodium were almost similar in all the formulations. It is found that 85% of Diclofenac sodium diffused out from the colloidal systems within 8hrs and practically all the drug was released within…

Results and discussion 3.1 Ionic conductivity measurements The complex impedance plots for the polymer electrolytes with different amounts of TBAI /LiI is shown in Fig. 1. It can be displayed that the ionic conductivity increases with the increase in TBAI salt content and reaches the maximum value of 1.737×10-3 S cm-1 at 298 K for 60 % of TBAI content, beyond decreases on further addition of TBAI. At a low content of TBAI, the conductivity is low due to the small number of charge carriers in…

The concentrations of difference between the membrane phase and feed phase based on the mechanism of mass extraction. In the case of feed solution represented radioactive simulated waste solution and dissolved in 0.5M HNO3. In the feed phase decreasing with H+ concentration. pH values at 2.5 into 5.5 in the feed phase. Fig,s(5a-5c). Shown the effect of hydrogen ion concentration in the feed phase and studied of pH range 2.5-5.5 for 0.5M HNO3. Stripping solution of 0.05M of EDTA. Initial…

Describe the Properties of Biopol Biopol is a copolymer made of the monomers PHV and PHB. PHB alone, with its short methyl side chain, is brittle and has very high crystallinity, meaning it cracks easily. Due to its high crystallinity and overall unsuitable properties for industrial use, PHV has been added to created PHBV, or Biopol. Biopol is semicrystalline, meaning it can still crystallize as well as melting at a lower temperature than PHB, making it industrially suitable. Due to its long…

Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered. The human body consists of various different types of enzymes,…

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

the painting-like photograph became more popular than the realistic photograph itself. For creating a pictorial photograph, the Combination printing method was used. People combined individual elements from separate images, and they put them into a new single image by manipulating multiple negatives or prints. The person who attempted this pictorialism for the first time was William Lake Price (1810-1896). Price gave his work, Don Quixote in his Study, Early 1850s, and won high…

The lab calculations resulted in an average of 21.7L/mol which was fairly close to the theoretical value, 22.4L/mol. In order to obtain that result through calculations, the water vapor pressure and the water height correction had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under…

potentially get any worse. How the contents of instant cold packs help them work. 2. Instant hot and cold packs work by using chemicals that wither absorb a lot of heat quickly or release heat when absorbed in water, when a process absorbs a lot of heat it’s called an endothermic reaction ; when a process releases a lot of heat it’s called an exothermic reaction, the chemical ammonium nitrate Is quite often used in cold packs because it absorbs a lot of heat when soaked in water, water and…

Abstract: Amylase in the body is used to break down polysaccharides into monosaccharides. The monosaccharides are simple sugars that are used to give the body energy. This effect was investigated in an experiment designed to show the breaking down of starch solution. A water bath was used to heat water up to 60oc. Pieces of dialysis tubing were wet and had starch solution put inside. Half of the measuring cylinders were filled with 60oc water, and the other half with 25oc water. Tests of the…
