    completion of this project. CHAPTER: I 1.0 Introduction Man’s constant evolution couldn’t have been possible without fuels. Society is putting more emphasis on the mobile transportation sector to achieve future goals of sustainability and on low thermal efficiencies of IC engine. About 60% of heat-energy liberated during combustion of fuel is not utilized in producing useful work and getting dumped into the atmosphere daily. To achieve these goals‚ society needs to jump to a new method to recover

    started to cool it. They found that as the material made the transition to the superconducting state‚ the flux was expelled. This is called the Meissner-Ochsenfeld effect. It shows that a superconductor is characterized by more than just perfect conductivity; it also displays perfect diamagnetism. There exist two types of superconductors:  Type I superconductor has one critical field‚ above which superconducting regions diminish in size and finally disappear in critical

    Topic 4 - Bonding 4.1 Ionic bonds 4.1.1 Ionic bond: +ve (cations) and -ve (anions) ions are attracted to each other and form a continuous ionic lattice 4.1.2 Group 1 metals form +1 ions‚ group 2 metals form +2 ions‚ metals in group 3 form +3 ions . Examples : Li+‚ Mg2+‚ Al3+. Greater ease of ionisation Li->Cs is due to the increased electron shielding of the nuclear attraction caused by additional inner shells of electrons. The easier atoms are to ionise‚ the more reactive they

    Manufacturing of Aerogel Aerogel was found by Steven Kistler in 1931‚ but its application cannot be in the market and consumer because there is no item that can use the aerogel. The 1980s the aerogel have a place to be a raw material in existing and new product after they discover a new research about aerogel. They have been considered as a new development material that better than polyurethane foam in refrigerators‚ and as a heat insulator for windows. Aerogel is produced by removing all the

    graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities‚ most of which originate from the strong covalent bonding between its atoms. In particular‚ diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells. Because of its extremely rigid lattice‚

    formed along the earth ’s crust. Some characteristics of the sulfide are is that it has a low melting point‚ rapid electrical exchange‚ resists high temperatures‚ degrades plastics in UV rays‚ has different pigments‚ and has high electrical and thermal conductivity. Cadmium sulfide is contained within the photocell. It relates to the photoelectric effect in that it acts as a photo resistor to different types of light. The photoelectric effect we know today is due to the significant contributions of
