chapter 8, Unbreakable, Miodownik discusses the significance and characteristics of various forms of carbon in a historical lens. Although derived from the same element, graphite, diamond, and graphene all have unique properties unlike any other materials. Miodownik begins by offering a relatable anecdote to his childhood art class in order to truly show the readers the prevalence and wonder of carbon. He then focuses the central idea of the chapter on the effect of structure on properties and…

combustion of fossil fuels even though carbon dioxide emissions (FFCO2) is known to be the largest driver of anthropogenic climate change. In this era of human-dominated influence on the environment it is important to note that climate change will have an irreversible effect on several global systems such as an increase in atmospheric and ocean temperatures, melting ice sheets, changes in precipitation patterns, rising sea levels and an alteration of the carbon cycle. (risa) With the increase in…

Carbon Cycling Internal Achievement Standard Science 90953: Demonstrate understanding of carbon cycling Carbon Cycling Internal What is the Carbon Cycle? Carbon is a key component in all living organisms and can be found in both living and nonliving organisms. Organisms will continue to contain carbon even when they change or decay. Carbon is found in a variety of living things and can exist as a solid e.g coal and diamonds, a liquid e.g crude oil or a gas, for example CO2…

Carbon Dioxide, is a natural occurring chemical compound that consists of one carbon atom and two oxygen atoms. On Earth carbon dioxide is released into the atmosphere from respiration, combustion of coal or hydrocarbons, and respiration. However most of the carbon dioxide that is released into the atmosphere is removed by organisms that conduct photosynthesis. Photosynthesis is the processes in which organisms, such as, plants, algae and cyanobacteria (bacteria that obtain their energy from…

seen by humans are going to be endured faster than anticipated and without combating the exponentially growing CO2 levels species on Earth may not survive and ultimately cause trouble for humans. Fifty-five million years ago, a sudden, influx of carbon gases flooded the ocean and atmosphere. This major change was caused by an alteration…

ABSTRACT In this work, a new flexible and transparent substrate with the help of organic materials such as Polydimethylsiloxane (PDMS) and Tetra ethoxy orthosilicate (TEOS) is synthesized. Transmittance of about 90-95 % is obtained in the visible region (400-700 nm) and the synthesized substrate show better thermal characteristics and withstands temperature upto 200 oC without any significant degradation. Characteristics such as transmittance (T), absorption (A), refractive index…

Crude oil is a complex mixture of various organic compounds, comprising of different hydrocarbons and heteroatomic compounds (Simanzhenkov and Idem, 2003). In addition to carbon and hydrogen, petroleum might contain sulphur, oxygen and nitrogen, and metals such as nickel, vanadium, iron, and copper. Crude oil physical and chemical compositions vary with location, depth and age (Rahimi and Gentzis, 2006). Physical composition of crude oil varies from black liquids of high viscosity to…

study was prepared with different molar ratios, n, ranging from 1 to 4 as shown in Equation (2.1). The result obtained was generally in the ratio of three SiO2 molecules to one molecule of Na2CO3 producing three molecules of sodium silicate and carbon dioxide gas released, shown as equation (2.2). Equation (2.1) n = SiO2 / Na2O Equation (2.2) 3SiO2 +Na2CO3 (3SiO2 , Na2O) + CO2 The result obtained was close to 3.3 : 1 (Brahmi, Merabet et al.…

when it is converted to gasoline. The DME is converted to gasoline range hydrocarbons over a zeolite catalyst. In the gasoline production reaction, some reactions cause unwanted components which may be regarded as impurities. These include carbon monoxide, carbon dioxide and light olefins. Gasoline with less impurities is regarded as of greater quality and sells at a higher price. A distillation column can be used to separate the desired hydrocarbons…

Carbon dioxide is emitted through many means, both naturally and by different human activities. Plants play a crucial role in limiting the abundance of carbon dioxide in the atmosphere. In general, photosynthesis can be explained by the following formula: 6CO2 + 6H20 + ATP → C6H1206 + 602. Using the carbon dioxide present in their environment, water from their roots, and energy from sunlight, a plant is able to continue to grow and conduct cellular respiration through this process. But how…
