Luminol Synthesis Lab Report
Luminol solutions use oxidation reactions to create the bright, luminescent, blue emission. In order to discover which additive enhances that glow the most and for the longest, I studied the data of several tests with varying enhancers added to the luminol. The substances to be compared in this study are as follows: cysteine, Cu (II), silver nanoparticles (AgNPs), and zinc sulfide nanoparticles (ZnS-NPs).
The first experiment focused on the reaction between alkaline luminol H2O2, the most common luminol solution, and cysteine, one of the twenty essential amino acids. In this experiment, 105 g=mL cysteine solution, 2.0 105 mol=L Cu(II) solution, and the mixture of 1.0 105 g=mL cysteine with 2.0 105 mol=L Cu(II) were tested. However, no

    Chemists often find a method to determine the level of “greenness” of a chemical reaction, or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic, coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck and Stille reactions. Palladium typically exists in the oxidation states of 0, +2, and +4. PdCl2 is usually the starting compound for several other heterogeneous palladium catalysts such as Pd/C and Pd/BaSO4.1 Suzuki coupling is an efficient way to…

    TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases, Transcription is located in the Nucleus, and the only type of RNA that is involved in Transcription is mRNA, and the purpose is so that the code can get out of the Nucleus, mRNA is also made through Transcription, It also takes information that doesn't directly make proteins but it helps makes codes for the production of proteins, DNA Transcription consist of 4 nucleotide bases, Adenine, Thymine, Cytosine, Guanine. Transcription also unwinds the strand of DNA and the RNA comes in and matches then becomes a single strand. The only thing that changes during this process is the Thymine gets replaced with Uracil.…

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation, the process in which a cell takes up and expresses a new piece of genetic information, the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their tools, and other supplies for as long as they need, and keep them from touching anything. They must also learn that tools can never be shared between specimens, and when they use a tool, they should dispose of it and get a new one. Next they need to learn how to transfer a bacterial colony. To do this, one must use a sterile loop and scrape one colony off of the dish. Then they must insert the loop into…

    The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets, respectively, were allegedly reporting higher amounts of iron in their products than actually existed, as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze the products and use the data to determine the true amount of iron in each product, as well as confirm that the iron was usable by the human body. The methods used to analyze the products, data, and results will be provided in the sections below.…

    1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry, how efficient the subject 's body is at utilizing the oxygen inhaled, as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min, the volume of oxygen was 0.84L/min. The RQ or RER was 0.87. Based on Table 5.1(Kenney,Wilmore, &Costill, 2012; Physiology of Sport and Exercise(5th ed.) The ratio indicates that roughly 68% of the kcal that the subject was using came from carbohydrates and the remaining 32% of the kcal came from fat. During the 50W stage the volume of carbon dioxide was 2.2L/min and the volume of oxygen was 2.9L/min. The RQ was 0.79, which indicates that the 33% of the kcal that the subject was using came from carbohydrates and that 67% of the kcal came from fat. In the 100W stage the volume of carbon dioxide was 4.08L/min and the volume of oxygen consumed was 4.1L/min. The RQ came out o be 0.99, the substrate being used was only carbohydrates at this point. The 200w stage had a carbon dioxide volume of 7.91L/min and a oxygen consumed volume of 6.51L/min. The RQ was 1.2 which indicates that the body is producing more carbon dioxide than the oxygen being consumed. The substrate being used for energy again is only carbohydrates.…

    Luminol is a chemical, which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents, but insoluble in water. Luminol is widely used by forensic investigators to detect even the slightest amounts of blood. The blue light is given off when iron is present in the blood. This means that iron serves as the catalyst in the light-producing chemical reaction.…
