El-Hallag2, M.A. Ghanem3 1,3Chemistry Department, Faculty of Science, King Saud University, Riyadh ,SA 2Chemistry Department, Faculty of Science, Tanta University, Tanta, 31527, Egypt Abstract. Polyaniline (PANI) thin films were successfully synthesized from a mixed solution of 1M aniline and two different concentration solutions of H2SO4 on a stainless steel substrate. The…

Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…

Exercise 2: Observing Bacteria Cultures in Yogurt Firstly, we created an incubator using a Styrofoam cooler with a removable lid and a small hole in the top which was used for placing a 7 watt light bulb in order to maintain a Microbe growing temperature of 35-37° Celsius. We also monitored the temperature with the use of a thermometer. A teaspoon of yogurt was then placed into a clean plastic container with lid. The container was then placed in the Styrofoam incubator, which was not…

3. Results and discussion 3.1. Grafting of CNT on the ramie fabric The schematic representation for the mechanism of ramie fiber surface treatments is shown in Fig. 2. For the alkali treatment of ramie fiber, the NaOH reacts with the hydroxyl groups of the ramie fiber as shown in Fig. 2(a). During silane treatment, the hydrolysis of silane takes place initially (Fig. 2(b)) which then reacts with the active hydroxyl functionalities in ramie fiber (Fig. 2(c)). Each silane molecule has three…

With the onset of television shows like CSI and NCIS, people have their own views of how the Criminal Justice System uses and obtains forensic evidence. One of the main issues with the media influence today is how people assume that forensics in the real world is exactly like the shows that portray it. “If people’s reactions to crime and criminals are generally shaped by the mass media, then it seems reasonable to assume that public reactions to criminal cases are shaped by shows like CSI”…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

The Extraordinary Science of Microbiology There are a wide variety of microorganisms in this world. The major groups of microorganisms include bacteria and fungi. These microorganisms are found all over the earth. The study of microorganisms started in the mid-1600’s. Most people believed that microorganisms only spread deadly diseases, but scientists proved that microorganisms can also be beneficial to human life. The wide variety of microorganisms that are found everywhere are most well…

Introduction: This essay would discuss the way the material of an object can be used for dating or distinguish the origin. Tang Sancai pottery produced in different parts of China. Because of the material for the production from local sources, chemical analysis can apply to see the origin of the ware. This shows the applicable method that can be used to for distinguish the Islamic lead-glazed ware from Tang Sancai as well as the Sancai ware from different part of China. For dating the tools…

Trace Evidence: Hair & Fibers Analysis Trace Evidence Defined as materials that could be transferred during the commission of a violent crime, trace evidence consists of multiple sources of which include hair, fibers, soil, gunshot residue, among many more. Trace evidence can be transferred between people, objects, or the environment during the commission of a crime (Federal Bureau of Investigation, 2016). This idea is known as the Locard exchange principle which is the idea that whenever…

the immobilization of the peptide, 1.5 μL of peptide solution was placed on the CNT channel and incubated for 4 h at room temperature. After the immobilization process, unbound peptides were washed out 2–3 times with distilled water. Atomic force microscopy (AFM) system (MFP-3D, Asylum Research, USA) was used to analyze the immobilization of the peptide. The pristine CNT channel was imaged at a scan rate of 0.2 Hz. After the peptide immobilization, the CNT channel was imaged again at 0.05…
