Introduction Throughout the world, millions of tons of plastic are produced annually and used in countless ways, from packaging to exfoliants in cosmetics (REF). Plastic’s wide popularity stems from its desirable properties, such as being aesthetically pleasing and cost effective. Much of the plastic on the market consists of disposable, one-time-use items. Discarded plastic then accumulates in the environment; so far many studies have shown that plastic accumulates in marine ecosystems…

Differences between Human Hairs and Animal Hairs Once determining that the fibrous evidence is a hair, our next step is on how to distinguish the feature differences between a human hair and an animal hair as shown in Table 8 (Sapp, 2004). (33 words) Animal Hair Coronal Spinous Human Hair Imbricate Table 8. Feature Differences between Human…

followed by a cooling to 25°C to erase the thermal history, then a second heating was made to 200°C. Heating and cooling rate was always of 10°C/min under nitrogen flow of 40 ml/min. The functional groups of PLA and LA can be analyzed by Fourier Transform Infrared Spectroscopy…

Introduction During the summer term, I held a Co-op position as a Research Assistant at Saint Mary’s University in the Chemistry Department. I was under the supervision of Kathy Singfield and Samuel Veres with the direct supervision by Brendan Grue. Objectives Objectives that we set prior to the start of my work term included assisting in the development of chemical methods involved in crosslinking, assisting in the investigation of the role of various factors including chemical additives.…

nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) techniques for morphological and structural confirmations. The dc- electrical conductivity of PPy-Au NCs was tested by two probe method. The electrical conductivity of…

Army National Guard Civil Support Teams Since 1998, Civil Support Teams have assisted local authorities in dealing with events involving chemical, biological, radiological, nuclear or enhanced improvised explosives (CBRNE). Whether it be a planned attack utilizing chemical or biological agents, toxic industrial materials, or radiological sources or an accidental spill or release. Highly skilled Army and Air National Guard Active Guard Reserve (AGR) personnel make up every Civil Support Team…

4.2.1.2.2 IR spectroscopy IR spectra of Tinidazole A small amount of Tinidazole was taken on butter paper then it was placed in desiccator for removal of moisture from the same. After the removal of moisture the sample was placed under IR lamp for complete removal of…

Abstract. In this work investigation for the effect of compressed CO2 on the morphology of the produced Polyaniline (PANI) was carried out. The conventional oxidative polymerization using ammonium peroxydisulfate as oxidizing agent was used with and without compressed CO2. The results showed that different morphologies of PANI nanorods and PANI nanoparticles were produced using the conventional polymerization with and without compressed CO2 respectively. Molecular characterization of the…

Below I am discussing, at length why I believe I should receive the Research Plus Award, addressing each point of the Researcher Excellence Framework, giving evidence how the past two and a half years have contributed to my personal and my career development. 1. Knowledge and Intellectual abilities a. Knowledge base Throughout my PhD I have been able to attend a number of courses organised by the QUB postgraduate centre, which allowed me to further my knowledge and gain valuable skills within my…

CHAPTER 4 RESULTS AND DISCUSSION 4.1 Incomplete Carbon Glucose Preparation for sulfonated solid acid catalyst must undergo a process which is called carbonization or pyrolysis. Glucose is natural organic compounds had been used as starting raw material because it is cheap and less toxic. Carbonization is an important step before the sulfonation process because it will form amorphous carbon composed of small carbon sheets [B] and produced sites for sulfonic group to be attached or…
