And Abiogenesis
Historical Development of the Distinction between Bio- and Abiogenesis. Robert B. Sheldon NASA/MSFC/NSSTC, 320 Sparkman Dr, Huntsville, AL, USA ABSTRACT Early greek philosophers laid the philosophical foundations of the distinction between bio and abiogenesis, when they debated organic and non-organic explanations for natural phenomena. Plato and Aristotle gave organic, or purpose-driven explanations for physical phenomena, whereas the materialist school of Democritus and Epicurus gave non-organic, or materialist explanations. These competing schools have alternated in popularity through history, with the present era dominated by epicurean schools of thought. Present controversies concerning evidence for exobiology and biogenesis have many aspects which reﬂect this millennial debate. Therefore this paper traces a selected history of this debate with some modern, 20th century developments due to quantum mechanics. It ¯nishes with an application of quantum information theory to several exobiology debates. Keywords: Biogenesis, Abiogenesis, Aristotle, Epicurus, Materialism, Information Theory 1. INTRODUCTION & ANCIENT HISTORY 1.1. Plato and Aristotle Both Plato and Aristotle believed that purpose was an essential ingredient in any scienti¯c explanation, or teleology in philosophical nomenclature. Therefore all explanations, said Aristotle, answer four basic questions: what is it made of, what does it represent, who made it, and why was it made, which have the nomenclature material, formal, e±cient and ¯nal causes.1 This aristotelean framework shaped the terms of the scienti¯c enquiry, invisibly directing greek science for over 500 years. For example, \organic" or \¯nal" causes were often deemed su±cient to explain natural phenomena, so that a rock fell when released from rest because it \desired" its own kind, the earth, over unlike elements such as air, water or ¯re.

Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions
J. Phys. Chem. A 2000, 104, 3655-3669 3655 Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions. 5. PAHs Incorporating a Cyclopentadienyl Ring† D. M. Hudgins,* C. W. Bauschlicher, Jr., and L. J. Allamandola NASA Ames Research Center, MS 245-6, Moffett Field, California 94035 J. C. Fetzer CheVron Research Company, Richmond, California 94802 ReceiVed: NoVember 5, 1999; In Final Form: February 9, 2000 The matrix-isolation technique has been employed to measure the mid-infrared spectra of the ions of several polycyclic aromatic hydrocarbons whose structures incorporate a cyclopentadienyl ring. These include the cations of fluoranthene (C16H10), benzo[a]fluoranthene, benzo[b]fluoranthene, benzo[j]fluoranthene, and benzo- [k]fluoranthene (all C20H12 isomers), as well as the anions of benzo[a]fluoranthene and benzo[j]fluoranthene. With the exception of fluoranthene, which presented significant theoretical difficulties, the experimental data are compared to theoretically calculated values obtained using density functional theory (DFT) at the B3LYP/ 4-31G level. In general, there is good overall agreement between the two data sets, with the positional agreement between the experimentally measured and theoretically predicted bands somewhat better than that associated with their intensities. The results are also consistent with previous experimental studies of polycyclic aromatic hydrocarbon ions. Specifically, in both the cationic and anionic species the strongest ion bands typically cluster in the 1450 to 1300 cm-1 range, reflecting an order-of-magnitude enhancement in the CC stretching and CH in-plane bending modes between 1600 and 1100 cm-1 in these species. The aromatic CH out-of- plane bending modes, on the other hand, are usually modestly suppressed (e 2x - 5x) in the cations relative to those of the neutral species, with the nonadjacent CH modes most strongly affected.

Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture
Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture Stephen Lucas 05/11/10 Measurement of Cp/Cv for Argon, Nitrogen, Carbon Dioxide and an Argon + Nitrogen Mixture Stephen Lucas With laboratory partner: Christopher Richards University College London 5th November 2010 Abstract: The ratio of specific heats, γ, at constant pressure, Cp and constant volume, Cv, have been determined by measuring the oscillation frequency when a ball bearing undergoes simple harmonic motion due to the gravitational and pressure forces acting upon it. The γ value is an important gas property as it relates the microscopic properties of the molecules on a macroscopic scale. In this experiment values of γ were determined for input gases: CO2, Ar, N2, and an Ar + N2 mixture in the ratio 0.51:0.49. These were found to be: 1.1652 ± 0.0003, 1.4353 ± 0.0003, 1.2377 ± 0.0001and 1.3587 ± 0.0002 respectively. The small uncertainties in γ suggest a precise procedure while the discrepancy between experimental and accepted values indicates inaccuracy. Systematic errors are suggested; however it was noted that an average discrepancy of 0.18 between accepted and experimental values occurred. If this difference is accounted for, it can be seen that we measure lower vibrational contributions to γ at room temperature than those predicted by the equipartition principle. It can be therefore deduced that the classical idea of all modes contributing to γ is incorrect and there is actually a „freezing out‟ of vibrational modes at lower temperatures. I. Introduction II. Method The primary objective of this experiment was to determine the ratio of specific heats, γ, for gaseous Ar, N2, CO2 and an Ar + N2 mixture.

Liquid Argon
Safetygram 8 Liquid argon Liquid argon is tasteless, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Belonging to the family of rare gases, argon is the most plentiful, making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds. Since argon is inert, special materials of construction are not required. However, materials of construction must be selected to withstand the low temperature of liquid argon. Vessels and piping should be designed to American Society of Mechanical Engineers (ASME) specifications or the Department of Transportation (DOT) codes for the pressures and temperatures involved. Although used more commonly in the gaseous state, argon is commonly stored and transported as a liquid, affording a more cost-effective way of providing product supply. Liquid argon is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires special equipment to store and handle cryogenic liquids. A typical system consists of the following components: a cryogenic storage tank, one or more vaporizers, a pressure control system, and all of the piping required for fill, vaporization. The cryogenic tank is constructed, in principle, like a vacuum bottle. It is designed to keep heat away from the liquid that is contained in the inner vessel. Vaporizers convert the liquid argon to its gaseous state. A pressure control manifold controls the pressure at which the gas is fed to the process.

PAH, fluorescence, UV-VIS, ERE, comet. Polycyclic aromatic hydrocarbons (PAHs) are considered as plausible carriers for the extended red emission (ERE), a photoluminescent process associated with a wide variety of interstellar environments, as well as for broad emission band features seen in cometary spectra. We report the absorption spectra of phenanthrene, anthracene, fluoranthene, pentacene, pyrene, chrysene and triphenylene isolated at 10 K in solid argon matrices together with laser induced fluores- cence (LIF) spectra at 355 nm of matrix-isolated anthracene and fluoranthene. LIF spectra are compared with the UV/blue fluorescence spectra of the Red Rectangle Nebula (RR). The LIF spectra measured in solid Ar matrices have been shifted to the predicted position of the PAH band emission in the gas phase for comparison with the astronomical observations (Fig. 1). These preliminary results indicate that small neutral PAHs can well account for the blue fluorescence observed in the RR as it has been previously proposed (Vijh, et al. (2004)). LIF spectra of anthracene measured in Ar matrices are also compared to the emission spectra of 1P/Halley’s inner coma(Fig.

It has been a common practice that in the deposition of a ceramic coating onto a sub- strate, a thin titanium interlayer is used to improve the adhesion between the coating and the substrate. But the structure and strength of the interlayer play an important role in determining the adhesion strength of the coating. This work involves the deposition of titanium diboride (TiB2) based nanostructured coatings on high speed steel substrates. A titanium interlayer was applied by sputtering a titanium target in pure argon atmosphere and in argon-nitrogen gas mixtures to affect nitrogen doping of the interlayer. Structural and properties analysis revealed that various contents of nitrogen gas in argon-nitrogen gas mixture during deposition by magnetron sputtering has significant effect on the adhesion between the TiB2 coating and the high speed steel substrate. There exists an optimum degree of nitrogen incorporation in the interlayer that results in the maxi- mum enhancement in adhesion. The beneficial effect of nitrogen gas mixing is discussed in terms of the modified structure and increased hardness of the interlayer, which provides stronger sup- port for mechanical loading.
