The progress of nanotechnology has encouraged scientists to continuously pursue new electrode materials for constructing an enhanced electrochemical platform for sensing. In this study, hydrothermally-assisted reduced graphene oxide (TRGO) was synthesized using an environment friendly reducing agent in optimum time to easily exfoliate coating solution and substitute on the microelectrode. Series connected distributed sensing electrodes were fabricated and patterned with TRGO added platinum…

This example argues that class sizes should be reduced for a better education system because of academic performance with and without it. Reducing class size positively impacts the students involvement through deeper relationships, comfort, efficiency and academic performance. These effects all work together to create a good environment for students to thrive in. Although some states have started on this journey it should become federal law. One reason classes should be reduces is the impact…

Investigating the light factors that affect the rate of photosynthesis in Elodea Fatima Hussien Sara House, Lesha Liles, Abigail Saucedo, Melrina Stemn Biology 1441_Sec 017, Monika Pradhan; October 6, 2015 All plants rely on photosynthesis, therefore, we examined the rate at which a submerged plant such as elodea photosynthesized, with different light factors. To do this, the elodea must be completely be submerged in deionized water, later place the two plants under artificial light and…

Fig. 1.1 Schematic principle of Electro Chemical Machining (ECM) 1.2 Principle of ECM Electrochemical machining removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The…

The purpose of this experiment was to see how single-replacement reactions change the physical matter of the original reactants. Hypothetically, the use of 2.120g of CuCl2 should react with the iron nails forming exactly 1 gram of copper. Upon starting the lab process, there was a displacement of 2.120 grams of CuCl2 into the plastic cup containing 50 ml DI water before joining the two iron nails. After the solution sat overnight, the iron nails became black in exterior color, orange copper…

protons as part of the process. The electrons from water are transferred to ubiquinone (Q) producing ubiquinol (QH2) (7, 8). The accumulation of protons generates a proton motive force (PMF); essential to diminish the thermodynamic gap of the standard redox potentials between NADH/NAD+ and QH2/Q to permit reverse electron transfer (RET) from QH2 to NAD+ by CMI(9) . By coupling the associated metabolisms of these two enzymes NADH is produced using light and water as substrates with oxygen as the…

For reactions with a medium, or “one to one”, ratio of iron (II) to hydrogen peroxide, the generation of hydroxyl radicals is also observed. In this particular ratio, the presence of organics does not seem to inhibit the effectiveness of the iron catalyst, as all the iron (II) was converted to iron (III) in a series of experiments. Without the organics present, the hydrogen peroxide reformed by reacting slowly with iron (III) to produce ferric salts, which then degrade into more hydroxyl…

Sarah Bounab BQD Experiment 2: Copper/Iron Stoichiometry Abstract: The purpose of the Copper/Iron Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between…

Experiment 1: Alkanes & alkenes: Combustion and action of sulphuric acid. Objective: To make careful observations and compare the difference(s) between alkanes and alkenes. Introduction: Hydrocarbons are composed exclusively of oxygen and hydrogen. There are three types of homogeneous hydrocarbons (whose members differ by one CH2 unit): alkanes, alkenes and alkynes. The difference between these three groups is in the bond types between the carbons. Alkanes form only single bonds, alkenes…
