11 August 2008First experimental demonstration of a Fresnel axiconKevin Gourley ; Ilya Golub ; Brahim Chebbi ;Author Affiliations +Proceedings Volume 7099, Photonics North 2008; 70990D (2008); doi: 10.1117/12.807162 Event: Photonics North 2008, 2008, MontrÃ©al, Canada An axicon, energywise, is the most efficient method for generating a diffraction-free beam. Yet one of the impediments to wide use of these optical elements is the cost related to the way they are manufactured. Recently we proposed a novel optical element-Fresnel axicon (Opt.Lett. 31, 1890, 2006) - which enables to overcome this problem while providing advantages such as compactness and very low bulk absorption. Prototypes of the Fresnel axicon were manufactured.In the present work we report the first experimental results characterising the optical properties of this novel device, which bridges the gap between diffractive axicons and their refractive counterparts.evin Gourley; Ilya Golub and Brahim ChebbiFirst experimental demonstration of a Fresnel axicon, Proc.

- If there is no symmetry in the molecule most of them will be observed the IR spectrum; the remaining modes will be observed in a Raman spectrum. The more complicated the molecule is (the more atoms it possesses and the lower the symmetry), the more peaks can be observed in the IR spectrum (see example 3 and 4). A signal is only observed in the IR spectrum, if the dipole momentum of the molecule changes during the interaction with the electromagnetic radiation.

Dispersive refraction effects in crystals Double refraction can be observed using crossed polarizers. Because of the asymmetrical geometry of the crystal, polarized light is separated into ordinary and extraordinary rays moving at different velocities through the crystal. The second polarizer recombines these rays to produce color by interference.ecause of the asymmetrical geometry of the crystal, polarized light is separated into ordinary and extraordinary rays moving at different velocities through the crystal.

What is a Non-Governmental Organization? In the logic of the language, there is no difference between a non-governmental organization and a private voluntary organization, but NGO still carries neutral connotations and applicability to a diverse range of political actors, whereas PVO suggests moral approval of a more limited range of groups.GOs, Political Parties and Ethnic Minorities. While a political party is not regarded as an NGO and cannot gain recognition at the UN, a small number of transnational groupings of political parties do gain consultative status with ECOSOC. There are also several groups of parliamentarians with consultative status.

Alkanes There is probably no upper limit to the number of carbon atoms possible in hydrocarbons. The alkane CH3(CH2)388CH3, in which 390 carbon atoms are bonded in a continuous chain, has been synthesized as an example of a so-called superlong alkane. Several thousand carbon atoms are joined together in molecules of hydrocarbon polymers such as polyethylene, polypropylene, and polystyrene.

Magnetocrystalline anisotropy The spin-orbit interaction is the primary source of magnetocrystalline anisotropy. It is basically the orbital motion of the electrons which couples with crystal electric field giving rise to the first order contribution to magnetocrystalline anisotropy. The second order arises due to the mutual interaction of the magnetic dipoles.

- And the science of smell is a really, really fascinating topic. Another important difference between these two enantiomers is their optical activity. So enantiomers exhibit different behavior when exposed to plain polarized light. So let's examine what I mean by that. So here we have our un-polarized light. Which is usually from a sodium lamp.

- A molecule that contains both a carbon-carbon triple bond and a benzene ring, for example, would exhibit some properties that are characteristic of alkynes and others that are characteristic of arenes. Alkanes are described as saturated hydrocarbons, while alkenes, alkynes, and aromatic hydrocarbons are said to be unsaturated. Aliphatic hydrocarbons

Chen Unit 5 a hydrocarbon containing only single covalent bonds; alkanes are saturated hydrocarbons. Methane and ethane are examples of alkanes. An alkane is a hydrocarbon in which there are only single covalent bonds. In any alkane, all the carbon-carbon bonds are single covalent bonds, and all the other bonds are carbon-hydrogen bonds.

Rotational States This formula should be modified if the molecule is too simple to have three principle axes. The graph below shows the absorption coefficient of water for light of various energies. For low energies, rotational and vibrational states cause the absorption of light. At higher energies, electronic excitation and photoelectric effect take over. It is only in the region around the visible spectrum that water transmits light well.

Alkanes Alkanes with branched chains are named on the basis of the name of the longest chain of carbon atoms in the molecule, called the parent. The alkane shown has seven carbons in its longest chain and is therefore named as a derivative of heptane, the unbranched alkane that contains seven carbon atoms.

- Isomerism. Alkanes are not just single carbon linked chains. If there are branches of carbons going off of the carbon chain, as long as the molecule still is single carbon-carbon bonds, and carbon-hydrogen bonds only, it is still an alkane.
