    In our previous report, 21 we investigated the influence of formulation variables of clotrimazole-loaded cubic liquid crystalline nanoparticles. The composition of chitosan tailored cubic nanoparticles was optimized employing central composite design. The findings of Small angle X-ray scattering analysis confirmed the presence of D and P cubic phases in nanoparticles. Most importantly, considerable improvement in mucin binding was observed upon incorporation of chitosan owing to electrostatic interaction between cationic chitosan-tailored cubic nanoparticles and anionic mucin layer of mucosa. The optimal conditions obtained were: fraction of Pluronic F127-8.33% (w/w) and concentration of chitosan- 0.17% (w/w). The optimal chitosan-tailored…

    Emma Kilgore Science Period 2 January 12, 2016 The Evaporation of Liquids When a liquid is left in a warm car over a certain period of time some people might notice that the liquid seems to have lessened. This is because of evaporation, evaporation is when a liquid changes into a gas because of an increase in temperature or pressure. This brings up many questions having to do with liquids and evaporation so, do all liquids take the same amount of time to evaporate? …

    High performance liquid chromatography (HPLC) is a separation technique utilizing differences in distribution of compounds in two phases; called the stationary phase and the mobile phase. The stationary phase designates a thin layer created on the surface of fine particles and the mobile phase designates the liquid flowing over the particles. Under a certain dynamic condition, each component in a sample has a different distribution equilibrium depending upon the solubility in the phases and or…

    High Performance Liquid Chromatography Lab Abstract High performance liquid chromatography or HPLC is the process in which mixtures are physically separated according to their polarity. The lab conducted, the separation of dyes in grape Kool-Aid, demonstrated the concept. This was done to display how different alcohols and their concentrations have different polarities, in which ties into HPLC. The lab consists of testing Kool-Aid, water, and different concentrations of methanol and…

    The objective goal of this experiment is to identify a set of unknown liquids by measuring the liquids of three physical properties which consists of determining the density, solubility and boiling point of the liquids A, B, C and D. Ethyl acetate, methanol cyclohexane and acetone were the unlabeled liquids. In the data analysis the predictions came out to be liquid A for acetone, liquid B is for ethyl acetate, liquid C is methanol and liquid D is cyclohexane. Introduction and Experimental…

    Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…

    Dissolve means to become or cause a liquid to be incorporated into a liquid to form a solution. The dissolved sugar in the water is a solution. The sugar is the solute; the substance being dissolved in the solvent and the water is the solvent, the liquid in which the solute is dissolved I to form a solution. The breaking of the bonds of sugar molecules causes the dissolving of sugar in water. When sugar is added to water the water particles become attracted to the sugar particles, which causes…

    Crystals form when a type of liquid cools down, and then hardens. The process when crystals grow is called "nucleation". Whenever a person eats salt, they are eating salt crystals. These crystals are called salt crystals. To make homemade salt crystals, the materials you need are hot water and salt. When dissolving salt in water, the salt is not changing its properties. This project will use different types of waters to see how many more crystals it will help grow. Dasani water is a brand of…

    3.1.3 Pump A pump is a gadget that moves liquids (fluids or gasses), or once in a while slurries, by mechanical activity. Pumps can be characterized into three noteworthy gatherings as indicated by the technique they use to move the liquid: direct lift, dislodging, and gravity pumps. Pumps work by some component (regularly responding or turning), and expend vitality to perform mechanical work by moving the liquid. Pumps work by means of numerous vitality sources, including manual…
