Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…

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…

Animal-Assisted Therapy as a Supplemental Treatment for Seasonal Affective Disorder Patients Ivey McCartney The University of Georgia Animal-Assisted Therapy as a Supplemental Treatment for Seasonal Affective Disorder Patients While some people may enjoy the crisp air and shorter days that accompany the fall and winter months, there are many who develop an annual occurrence of depression during these months. This disorder is known as seasonal affective disorder, or SAD. The disruption of…

INTRODUCTION Background The macrocyclic organic molecules Phthalocyanines (1) which are comparable to the naturally occurring porphyrin (2) ring systems shown in (Figure 1). The porphyrin molecule consists up of four pyrrole subunits which are associated in n-conjugation by methine carbons. 1 2 Figure 1: structures of phthalocyanine and porphyrins molcule The compound…

low natural contents. Its concentration is about 4 ng g−1 in basic rocks and 1 ng g−1 in soils.8 The concentration of gold in environmental, geological and metallurgical materials is usually too low to be determined directly by atomic absorption spectroscopy owing to insufficient sensitivity and matrix interferences. Hence, separation and enrichment of analyte are important aspects in determination of gold.9 Various techniques have been used for separation and preconcentration of gold, such as…

Pharmaceutical synthesis involves various methods and techniques. These techniques are crucial and require profound knowledge and understanding of the chemistry and handling of drug compounds. A pharmaceutical drug (also referred to as a pharmaceutical, pharmaceutical preparation, pharmaceutical product, medicinal product, medicine, medication, medicament, or simply a drug) is a drug used to diagnose, cure, treat, or prevent disease.[1] Most drugs are natural: collected from sources such as…

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…

Space is a vast and unexplored region, the exploration of which is necessary to satiate mankind’s curiosity and answer the enduring question, “What is our place in the universe?” The need to explore and understand the universe we live in has driven us to establish government agencies, such as the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA), whose main goal is to study outer space. NASA’s projects have led to many great advancements, including the…

Brain Science will Change Communication Mode Communication has long been a significant issue. Although human has created language to help they get the mind of the others and the Internet makes transmitting information faster and more convenient, communication is still imperfect. For example, it is almost impossible for one to share feelings, image and memory in their mind integrally. Actually, people have to use literature,music and many other forms of expression to express themselves. But…

desires for fundamental research. These ambitions were fueled by the complications he faced as a result of his religious family. Employing his adversity, Rowland later advanced to become a renowned scientist to revolutionize not only the design of spectroscopy but also the perception of scientific research in the late 19th century. He redirected his suppressions of the world to further develop this study of “pure science,” the understanding that science should focus on research for the…
