Renewable sources of energy Nicholas Reibel Northeastern University 8/12/14 Abstract Environment degradation has taken a global dimension. Human activities continue to cause interfere with the natural surroundings. The balance of the ecosystem has been defiled due to technological advancement, prominence of materialism, human greed, and misuse of nature and egoism of human nature. Non-renewable energy sources have been cited as responsible for environmental degradation. Efforts have…

Parametric study and Optimization of C.I Engine Using Plastic Pyrolysis Oil for low NOx emissions Using Taguchi Method Abstract: Fossil fuel shortage and severe environmental problems have attracted great attention on the exploitation of clean renewable energies. The utilization of lignocellulosic biomass resources will play an increasingly important role in the future. The objective of the study is to optimize the parameters such as plastic pyrolysis oil diesel blend %, injection pressure and…

Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

Unfortunately, beneath the flourish of life was the dark discovery of tar sands. Tar, or oil sands are composed of sand, water, clay, and bitumen- a thick, dark, and heavy oil. Because of its viscosity, bitumen needs to be lightened with a mixture of hydrocarbons to transport it through pipes. The mining of bitumen began in 1719 when it was first discovered, and small extractions were attempted in the 1920s and throughout World War II. The first commercial bitumen mining began in 1967. and…

buoys. he thought that the buoys could use an upgrade and the weber grill was born and backyard grilling was never the same. When meat is grilled there are two types of chemical reactions that occur the first one is known as PAHs (polycyclic aromatic hydrocarbon) this occurs when the fat from the meat creates smoke this smoke then goes back into the meat itself. The other chemical that is created is known as HCAs (heterocyclic amines) it occurs when amino acids, sugars, and creatines react…

Emission of Particulate Matter (PM10, PM2.5, and PM0.1) comprises a considerable fraction of urban air pollution (Laden et al. 2006, Shackleton et al, 2013). Long term exposure of airborne particulates matter is directly associated with post neonatal infant mortality (Laden et al. 2006), Sudden Infant Death Syndrome (SIDS) (Tracey et al. 2006) and various disease conditions such as; cardiopulmonary, lung cancer (Pope III, 2002), atherosclerosis (Araujo, 2011) and asthma (Anderson et al., 2013).…

Soap and Detergent Soap and Detergent are the cornerstones of human cleanliness. Soap is, “a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added”( Soap 2018 ). Detergent is, “ a water-soluble cleansing agent that combines with impurities and dirt to make them more soluble and differs from soap in not forming a scum with the salts in hard water” ( Detergent…

years. Throughout this duration of time, at least 700 000 tonnes of toxic by-products were produced due to smelting and steel production processes. Some of the by-products produced were total petroleum hydrocarbons (TPHs), benzene, toluene, ethyl-benzene, xylene (BTEX), polycyclic aromatic hydrocarbons (PAHs) and heavy metals. The toxic by-products were dumped into a tidal estuary that empties into the Sydney Harbour which ultimately lead to the toxins being released into the Atlantic Ocean. …

Tebboth, and Tremaine from British Oxygen tried to synthesize amines from hydrocarbons as a modification of the Haber process.1 Their work and discovery was published three years later in 1952, but they did not deduce the pentahapto sandwich structure.1 Woodward and Wilkinson determined the structure based on its reactivity, and their discovery led to a newfound interest in structures containing d-block metals and hydrocarbons.2 Ferrocene, as shown in Figure 1, is an organometallic compound…
