covalent at attachment [27-28]. In the present work, we report the performance of a graphite paste electrode (GPE) modified by polyaniline and polypyrrole, for detecting of urea in laboratory samples using amperometric technique with addition of polyaniline (PANI) and polypyrrole (Ppy) a good conducting polymer supporting to graphite paste. The superior performance polymers modified graphite paste electrode is demonstrated by the speciation and determination of urea forms in pharmaceutical formulations

This can happen in the situation where ion channels embedded in the support of the tethered bilayer membranes. This always attached with the electrode that is of gold, as a result, the electrical circle comes into existence. The molecules that are being captured for example antibodies to control the flow of the ion and this binds the target molecule, this control on the flow is through a channel

Abstract Aim: Green tea is healthy beverage and is a part of day to day life. Similarly, chamomile tea is known for its asprin like properties. Beneficial effects of these tea include such as protection against dental caries, periodontal disease and tooth loss and found that can a decrease in streptococcus mutans count as well as increase in pH. Hence the present study was done to compare the pH of saliva and plaque, before and after the intake of green tea and to evaluate the role of green tea

3.3.2 pH Analysis The pH will be determined using an electrode with a penetration probe coupled to a calibrated portable pH meter. The samples will be analyzed in triplicate per treatment, and the mean value will be obtained from the fish sample. 3.3.3 Acidity analysis For the determination of acidity, 10g samples of three fish sample from each treatment will randomly selected, crushed and homogenized with 200 mL of distilled water in an Ultra-Turrax homogenizer for 1 min. This solution will be

In Experiment 5, “Spectrophotometric Determination of Iron in Vitamin Tablets” we will discover the importance of spectrophotometry which is a way to measure how much light is absorbed by a chemical substance that will measure the potency of light as beams in order to detect the light in a sample solution. Spectrophotometric is a quick, reliable method that measures light in a quantitated way, ensuring that electromagnetic radiation may be absorbed by matter. In order to understand how radiation

Intraparenchymal Electrodes are another way of getting signals from the brain. This method holds much more promising results than EEG because the receiver is placed directly in the brain of subject, getting many more, clearer signals. This allows more in depth control of 3 dimensional objects such as robotic arms. With enough concentration and practice, a person can even use the arm for basic motor functions such as eating and lifting objects. Intraparenchymal Electrodes have been a huge breakthrough

measurement using a pH meter and electrode. Procedure: In this lab we worked with several compounds, and we titrated an unknown weak acid as well as a known amount of potassium hydrogen phthalate. On day one we were tasked with filling several test tubes with a few milliliters of various solutions (pH 7, HCl, deionized water, H3BO3 NaHCO3, etc.) and evaluating the pH of each substance (refer to table I). The pH was evaluated using a pH meter as well as an electrode. Before the evaluation was performed

Generally, the process of maturation of rice wine need place it into containers for several months or one year prior to conducting the accelerated maturation. After one year, the rice wine was matured by an ultrasonic process. It is can be seen from figure 1 which is a diagram of the ultrasonic waves. In order to generate ultrasound energy to the rice wine, a 20 kHz ultrasonic wave generator was used. The ultrasonic wave generator had piezoelectric chips which generated electrons, then it accumulated

August 2014 Partners: Luke Silveira and Tivanka Anandappa Introduction: This practical involved investigating the behaviour of equipotential and electric field lines between two electrodes (which represented the a parallel plate capacitor). Furthermore the effect of adding a conductor and an insulator between the two electrodes was explored to determine the electric potential produced from these configurations. The setup involved three of paper with low conducting teledeltos paper on top to allow
