  • Physics Of Q-Dots Lab Report

    collected to particle size. 1 Atomic Force Microscopy Characterization In 1986, Binnig and Quate demonstrated for the first time the ideas of Atomic force microscopy, because people wanted to investigate electrically non-conductive materials.3 AFM experiments in tapping mode were performed to study the nanoparticles characterizations of that CdS-Glutathione Q-Dots sample. This is based on the image conducted using MFP-3D Origin AFM instrument (Asylum Research). For preparation, the sample diluted the complex (Df > 10,000), dried on a silica plate then scanned by AFM and determining diameter from changes in height. AFM analysis can be zoomed in, studied, and provided details of a region of interest. Two attempts used tap DI water and Reverse Osmosis water (RO Water). AFM images were processed using the Gwyddion software that can help to process the images and make them more clear (i.e. 3D images). Thermal analysis- TGA Characterization Thermal gravimetric analysis (TGA) is used to determine the thermal stability and characteristic of the organic capped materials that exhibit either mass loss or gain due to decomposition. TGA was performed using TGA Q500 (TA Instruments). Samples of about 7 mg were used for the experiments at a heating rate of 10 °C/min ramp to 800 °C. The samples were loaded without being pressed into an open platinum plate, which has a very high melting point that will not be damaged. And it is easy to clean by flame. It was loaded and weighting the…

  • Ro System Lab Report

    [RO-System] Reverse Osmosis, known as RO system, is a technology that is used to remove a large majority of contaminant from water by pushing the water under pressure through a semi-permeable membrane. To understand the purpose and the process of Reverse Osmosis, should understand the natural Osmosis operation. Natural Osmosis: The phenomenon of osmosis occurs when pure water flows from a dilute saline solution through a membrane into a higher concentrated saline solution. (Example of osmosis…

  • Forward Osmosis Essay

    The forward osmosis (FO) process is an emerging separation/desalination process. It is rapid process compared to other membrane processes such as reverse osmosis. The physical phenomenon of forward osmosis (FO) can demonstrated as the motion of water molecules through a semi-permeable membrane due to difference in osmotic pressure driving force through the membrane. The membrane enables only water molecules to pass through when salt molecules are rejected. The forward desalination technique…

  • Homeostasis: Cell Membrane Proteins

    move from higher concentration regions to lower. The cell membrane selectively restricts diffusion so ions move across the membrane by crossing the lipids or going through a channel. "Alcohol, fatty acids, and steroids can enter cells easily, because they can diffuse through the lipid portions of the membrane." (Anatomy and Physiology Textbook 86) The rate of diffusion is affected by surface area available and temperature because it affects the way that the partials move. Although osmosis may…

  • Deception And Deception In Helen

    In the play Helen by Euripides the main character, Helen often finds herself in complicated situations. To get out of those situations, Helen believes that her only option is to manipulate, deceive, and lie to people. Helen’s main goal is to be reunited with her husband, Menelaos, in her homeland. Helen persuades characters to do things her way by manipulation, lies, and deception. Throughout Helen, the main character manipulates Teucros, Menelaos, and Theoclymenos using deception, persuasion,…

  • Diffusion And Osmosis Lab Report

    Amber Rosales Marco Avalos Lab Section 2011. 21 1 October 2015 Diffusion and Osmosis There are many processes and systems that help maintain our body’s homeostasis and ability to function. These processes can be traced right down to a cellular level. However, if a process at this level were to be disrupted, it can create a ripple affect that can target major life functions or cause a long-term illness. It is processes such as Osmosis and Diffusion that contribute to our state of being and…

  • The Importance Of Diffusion

    The solvent, usually water, moves from a hypotonic solution to a hypertonic solution to make an isotonic solution (Reasoner 2011). This helps the body maintain homeostasis. A principle of osmosis is that water molecules move through the plasma membrane, for the solute molecules cannot (Tortora and Derrickson 2014). Solutes are also able to use force, called osmotic pressure, in a solution with impermeable solutes. There are three osmotic conditions referred to as hypertonic, hypotonic, and…

  • Lab Report: Osmosis And Diffusion Egg Lab

    Osmosis and Diffusion Egg Lab In this lab, an egg is used as a representation of an actual cell, the shell being the cell wall, and the yolk being the nucleus, which like an actual cell also expands when placed in a substance like water, and shrinks when placed in a thick substance like corn syrup. I hypothesize that water will make the egg hypotonic, which means that the cell is swollen due to an excess of water in its environment and corn syrup will make the egg hypertonic, which is the…

  • Water And Osmosis Experiment

    Our guiding question was: How does the concentration of salt in water affect the rate of osmosis? Osmosis is the spontaneous net movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Osmosis also refers specifically to the diffusion of water molecules. Diffusion is the movement of chemical particles for an area of high concentration to an area of low…
