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. Gold 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…

Uranium and its decay products can be found in the environment through a wide array of anthropogenic activities such as mining, nuclear and power generation industries and the production of phosphate fertilizers .(Sprynskyy et al. 2011) They pose a severe, long term ecological and public health threat (Khani 2011, Landa 2003) and therefore there is a considerable effort in the removal of these pollutants before their final discharge in the environment, as well as their recovery as an energy…

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…

4.4 Interpretations The data collected from this study are not strongly affected by convective fluid flow in the wellbores or surrounding strata. Rather, the geothermal gradient profiles show a more conductive thermal regime in the vicinity of the wells. Unfortunately, the wells are too shallow to make more significant observations of the deep thermal regime, but the high geothermal gradients in the Paliza Canyon and E10 wells show some promise of quantifying temperatures of a geothermal…

CHAPTER 5 EXPERIMENTATION 5.1 Spur gear terms and concept Fig. 5.1 Terminology definitions for spur gears The radial distance from the pitch circle to the outside diameter is called as addendum. The radial distance between the pitch circle and the root diameter is called as dedendum. The distance of the arc along the pitch circle from one side of a gear tooth to the other is called as circular thickness. The length of the arc of the pitch circle from one point on a tooth to the same…

Magnetic resonance imaging, also known as an MRI scan, is a type of scan that uses magnetic fields and radio wave energy to create images of the organs and tissues, such as the brain. It is a scan that is used to detect things such as tumors, infections and injuries. It is often used after an x-ray or CT scan is done to gather more information. This paper will discuss MRI in depth such as how an MRI works, its use in society, the differences between MRI and other scans and the future for MRI.…

Trichloroethylene (TCE) is defined as a Priority Pollutant covered under the Clean Water Act. The chemical is an organic vapor, and is a component used in degreasing, distillation, and painting operations (Woodside, 1999). Trichloroethylene is a liquid used as a solvent, and in other compounds (Environmental Protection Agency, 2011). Annually 10 million pounds of Trichloroethylene is used to manufacture Polyvinyl Chloride (PVC) (Gilbert & Heuvel, 2014). While current figures are not…

The experimenters followed their experimentation with analysis of the data obtained. The experimenters first contemplated the applicability of the Probe Comp test signal to biological systems. The experimenters reasoned that the test signal was not an effective description of a biological system because the test signal did not exhibit the noise present in biological systems. While considering the observations of the oscilloscope and biological systems, the experimenters considered which settings…

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…
