  • A Summary Of Moso Bamboo

    A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

  • Nimodipine Research Paper

    NIMOTOP INJECTION Nimodipine 0.02% solution contains the following excipients: Ethanol 96%, Macrogol 400, sodium citrate, citric acid, Water for Injections Ph. Eur. These excipients consist of properties that aim towards the proper functionality of Nimotop. They consist of inherent stabilities that cause little or no effect in the stability of the drug and they do not have any acute or chronic toxicity. The excipients are also added into the Nimodipine 0.02% solution to enhance the biological…

  • Formula Of Sulfate

    Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…

  • Leukocyte Gcrete Lab Report

    To determine optimal pH value for the hydrolysis of p-NPG by leukocyte GCase, we examined effects of variable pH (4.0-5.5) at a constant substrate concentration (5mM). Figure 1 shows the pH activity curves of leukocyte GCase assayed in the presence and absence of 6 mg per ml Sodium taurocholate. In the absence of the pure sodium taurocholate, the activity in the range of pH 4.0-4.8 was considerably lower. However, in the presence of pure Sodium taurocholate, leukocyte GCase was optimally active…

  • Baking Soda And Vinegar Lab Report

    Experiment 1. Title: How does the amount of baking soda affect its reaction with vinegar? Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid). Hypothesis: If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with. Equipment:  Baking Soda  Vinegar  5 glasses  Safety glasses …

  • Acid Base Titration Essay

    Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH 10. The endpoint was reached when the moles of the base being used became…
