This Nanotechnology Seminar focusses on the research, developments, advantages and disadvantages of Nanotechnology.

Nanotechnology is perceived as one of the key technologies of the 21st century with an aim of building the future, atom by atom. In a few decades, this emerging technology will let us inexpensively arrange atoms and molecules in most of the ways permitted. It will let us make supercomputers that fit on the head of a pin and fleets of medical nanorobots smaller than a human cell able to eliminate cancer, infections, clogged arteries, and even old age.

But,though the technology has developed rapidly over the years,there are still some challenges which are to be met and even they are discussed in this project.

This Nano Technology and Prototyping Mechanical Seminars provides a brief overview of the problems and benefits created by Nanotechnology, and substantiates the claim that a variety of ethical systems will be necessary to deal appropriately with the range of issues raised by nanotech.

Any organization has an explicit or implicit code of ethics: rules that its members are expected to follow. There are at least three ethical systems that are commonly used to administer different types of resources. Resources that can be traded to mutual benefit are best administered with Commercial ethics, which include honesty and efficiency. Things that can be freely duplicated, producing unlimited benefit, are best handled with Information ethics, which maximize the accessibility and utility of such resources.

Nanotechnology presents a wide range of problems and opportunities by making most existing products quite a bit more powerful and flexible.It promises to bring about abundance and rapid improvement of technology at low cost and high convenience.

CONCLUSION:

Hence, the project throws light on  the power of Nanotechnology as a technology, then surveys the risks, commercial opportunities, and abundance that may be created by nanotech and also the need for the deliberate development of collaboration between diverse organizations with radically different ethics.

This Metallurgical Changes in Steels Due To Cryogenic Processing & Its Applications is based on the study of improving the wear resistance and the significance of treatment parameters in different materials.

The cryogenic processing is modification of a material or component using cryogenic temperatures i.e temperatures below 120K (-244F, -153C).  Cryogenic processing makes changes to the crystal structure of materials.It is a supplementary process to conventional heat treatment process in steels and unlike simple coating,but effects  the entire volume of the component The major results of these changes are to enhance the abrasion resistance and fatigue resistance of the materials..

This project makes a study on the improvement in wear resistance and the significance of treatment parameters in different materials. It is found that cryogenic treatment imparts nearly 110% improvement in tool life. It is even superior to tin coating,

APPLICATIONS:

• Gun barrels: Cryogenic treatment increases the wear life of the barrel and makes cleaning easier and faster. Cryo-Accurizing permanently relieves the internal stresses cause twisting and arcing as the barrel heats up from repeated firing. with no risk of damage to the barrel or the action of a fine gun
• Grinding: Cryogenically treated grinding wheels cut more cleanly. Cryo-Accurizing permanently relieves the internal stresses with no risk of damage to the barrel or the action of a fine gun
• Engine parts: Knowledge of the effect of cryogenic processing on engines and power plants comes mainly from automotive racing applications

This Latest Trends in Automobiles Mech Eng Student Technical Seminar discusses the latest trends in automobiles The objective of this project is to provide an intermediate solution to the problem of limited fossil fuels in the form of HYBRIDS(Hydrogen, electric-fuel cell and bio-diesel)

The present generation automobiles are running with battery and electric system. Electric automobile is a motor vehicle powered by rechargeable batteries without the use of other fuel. The advantage of these hybrid vehicles is: in both systems, the battery is recharged while driving. At times, when the car is coasting. Neither gasoline nor electric power is needed, they need not be plugged into an electrical outlet for charging. So, fuel is not wasted while idling.

The project discusses on The Hybrid drive runs on both the gas and the electric motors to produce continuously variable output, a process the inventor calls “torque amplification”. The parts of automobile that transmit power from the engine to the driving wheels make up the power train. But the latest trend in automobile is “hybrid power train” which gains respect for providing a transition strategy from hydrocarbon fuels to a carbonless society and enables renewable energy sources.

CONCLUSION:

This project projects on what the research and development in automobile manufacturing is centered on i.e substituting fossil fuels.  Hydrogen electric fuel cells, with hybrid accord is the current trend. As hydrogen is an present in abundance and productive fuel with many potential uses,transition to “Hydrogen Economy” is on its way barriers do exist and makes hydrogen the energy of the future.

This Gasoline Electric Hybrid Car Mechanical Final Year Seminar Report designs and describes the mechanism and operation of Gasoline-Electric Hybrid Car. The major concern that Auto Industry have today is to use technology in manufacturing cars that reduce tailpipe emissions,improve mileage and not contribute to Green-house effect.In order to answer these concerns,hybrid cars have been produced.

Any vehicle is a hybrid when it combines two or more sources of power.This project describes the design and mechanism of a  Gasoline-Electric Hybrid Car which is an improvement over the electric car, which uses gasoline engine along with electric motor powered by batteries. The key to a hybrid car is that the gasoline engine can be much smaller than the one in a conventional car and therefore more efficient

CONCLUSION:

The Hybrid Car discussed in this project have had a large scope over the past four years, more than 100,000 hybrids have been sold in the United States and more than 17 million new cars and trucks that are sold in the U.S. each year.Three hybrid cars are now available at present — the Honda Civic Hybrid, the Honda Insight and the Toyota Prius.

This Coming Clean With Fuel Cells Mech Seminars For Students discusses how the use of Fuel cells help in converting waste water into clean water and electricity.

In the historical and the present-day civilization our existence is more dependent upon energy. The conventional sources of energy, the single most important pre-requisite for power generation, are depleting fast. But, as we are running out of these energy resources,the world is heading towards a global energy crisis. Hence,the greatest task today is to exploit the non-conventional energy resources for power generation.One such alternate source of energy is  Fuel Cells.  Fuel cell is considered to be an Electro chemical device for the continuous conversion of the free energy change in a chemical reaction to electrical energy.

This project discusses it’s role in wastewater  tratment plants and also presents an innovative emission-offset project that utilizes Anaerobic Digester Gas-powered(ADG) fuel cells to produce electricity. They efficiently generate premium quality electricity and much needed thermal energy, while consuming ADG and emitting negligible amount of regulated pollutions, and are currently under intensive development by several manufacturers for both stationary and mobile applications.

• The concept of using fuel cells powered by hydrogen gas provides the ideal solution to pollution in our world.
• Fuel cells have been developed that can be used for virtually any application requiring electrical power or mechanical energy.
• For portable applications such as laptop computers, cameras, and cell phones, direct methanol fuel cells (DMFCs)are future replacements for batteries.
• In Automobile Production, proton exchange membrane (PEM) type fuel cells are used.
• They eliminate the need for many of the world’s fossil-fuel power plants.

 CONCLUSION:

The project discusses how fuel cells are used for different applications and also explains that it can be used in anywhere with the help of specially manufactured converters that make the fuel cell power system adaptable to any country regardless of voltage or frequency allowing the production of truly “universal” power systems. The fuel cells cost is also very low.
