Natural Gas Diesel Fuel
733 wordsWe have known for a long time that eventually our oil deposits will dry up, and it would be helpful at that time if we had some kind of alternative fuel to power all of the machines that we use. Over the past two decades more oil has been pumped than has been found in the world. For this reason scientists have been looking to potential alternative fuels for the future. One of these alternative fuels may come in the form of natural gas. Natural gas has been found to be more plentiful than oil, an...

Raw Material High Temperature
1,217 wordsIntroduction First we will start with the definition of refractories and ceramics. Refractories and ceramics are non-metallic materials capable of maintaining physical and chemical stability at high temperatures. Refractories in modern practice are usually ceramic in nature, and are used in a wide variety of primary, secondary and tertiary industries. Wherever an industrial process involves heat in excess of 700 to 800 degrees Fahrenheit (roughly), one will find refractory material in place, eit...

Thermal Expansion Physical Properties
1,122 words... nitride. Cubic boron nitride is the second hardest known substance, after diamond, and has some special applications, such as abrasives in grinding wheels and cutting tools. It does not exist in nature and is thus made synthetically. Titanium nitride is used widely as a coating on cutting tools. IT improves tool life by virtue of it's low frictional characteristics. Silicon nitride has a high resistance to creep at elevated temperatures, low thermal expansion, high thermal conductivity, and ...

Cooling Rate Of Coffee
1,679 wordsExperiments to Determine the Cooling Rate of Coffee, when Milk should be Added and what Container should be Used The aim of the first experiment was to find out and record the cooling rate of coffee under three different conditions and thus showing when milk should be added assuming you have a phone call. The three different conditions were chosen because these were the most likely situations encounter by someone who is making a cup of coffee. We used Tain instruments to accurately calculate the...

Catalytic Converter Carbon Monoxide
705 wordsIntroduction There are millions of cars on the road in the United States, and each one is a source of air pollution. Especially in large cities, the amount of pollution cars produce everyday is a lot. To solve those problems, many laws have been enacted restricting the amount of pollution that cars can produce. To make their cars as pollution-free as possible, automakers have made many refinements to car engines and fuel systems and have developed the catalytic converter. The catalytic converter...

Carbon Monoxide Carbon Dioxide
4,029 wordsThe Exhaust Systems Exhaust Systems The exhaust system on a car is the most important device to keep our environment clean. Many exhaust emissions from the engine such as water, oxygen, nitrogen, and carbon dioxide, are of little concern. Others, such as hydrocarbons (HC), oxides of nitrogen (NO), and carbon monoxide (CO), can cause environmental and health problems if not controlled. Hydrocarbon emissions react with sunlight, which cause photochemical smog. The exhaust system controls these the...

Printing Process Requires Printing Process May Begin Screen
437 wordsThe Hybrid Printing Process INTRODUCTION The printing for hybrid circuits is a fundamental process in which the conductors, resistors and overglaze are put onto a ceramic tile called a substrate. While conductors, resistors and overglaze are not printed at the same time, the process is the same. Thus it is very important that anyone who is in the microelectronics field should know the basic process. While the process may change, depending on technology used, the same basic principles will remain...

Fuel Cells Power Plant
2,168 wordsCHEMISTRY CAT 2: INVESTIGATION OF A CHEMICAL QUESTION Question: How does ceramic fuel cells work and is it going to be the future energy source? DEFINITION, KEY IDEAS AND CHEMICAL CONCEPTS: A ceramic fuel cell is an all solid-state energy conversion device that produces electricity by electrochemically combining fuel and oxidant gases across an ionic conducting oxide. This third generation fuel cell is the most versatile with the highest conversion efficiency rate and very flexible in choosing t...

Amount Of Energy Magnetic Fields
1,648 wordsWeve all heard Untitled INTRODUCTION Weve all heard about superconductivity. But, do we all know what it is? How it works and what are its uses? To start talking about superconductivity, we must try to understand the how " normal" conductivity works. This will make it much easier to understand how the " super" part functions. In the following paragraphs, I will explain how superconductivity works, some of the current problems and some examples of its uses. CONDUCTIVITY Conduc...
