The Effect Of Solvent Type On The Infrared Spectrum Of Carbon Monoxide Adsorbed At Platinum Electrodes, Mark Anderson, Daniel Blackwood, Thomas Richmond, Stanley Pons

Mark R. Anderson

The infrared spectrum of CO adsorbed on a platinum electrode from several solvents was investigated. In N-methylformamide, acetonitrile, and 1,2-dichloroethane, the infrared band attributed to linearly bonded CO had experimental Stark tuning rates of 20 cm−1/V, 22 cm−1/V, and 19 cm−1/V, respectively. For each of these solvents, the potential dependence of the band position was found to be linear for the entire potential range investigated. When methanol was the solvent, the plot of the band position versus potential had three distinctly linear portions, each with a different value for the slope. The behavior is explained in terms of the ability …

The Behavior Of The Infrared Spectrum Of Carbon Monoxide Adsorbed At Platinum Electrodes From Non-Aqueous Solvents, Mark Anderson, Daniel Blackwood, Stanley Pons

Mark R. Anderson

Electrochemical oxidation of vanadium hexacarbonyl anion, V(Co)6 in aprotic solvents results in formation of the V(0) complex which decomposes to form CO in high concentrations next to the electrode surface. As a result, CO is more rapidly adsorbed on the surface than by conventional methods. Surface reflection infrared spectroscopy shows that the potential dependent frequency shift for the infrared active bands due to CO adsorbed on platinum is 19 cm−1/V in 1,2-dichloroethane and 22 cm−1/V in acetonitrile, which are considerably less than the 30 cm−1/V observed in aqueous systems.

Surface-Enhanced Raman Study Of The Effect Of Electrode Potential And Solution Ph Upon The Interfacial Behavior Of 4-Pyridinecarboxaldehyde, Mark Anderson, Dennis Evans

Mark R. Anderson

Surface-enhanced Raman scattering (SERS) spectra were obtained at a silver electrode in aqueous solutions at potentials from -0.2 to -0.6 V vs SCE and pH 1-7. The forms of 4-pyridinecarboxaldehyde that are adsorbed parallel those present in solution. In particular, the fraction of adsorbed species that is protonated at -0.2 V varies with pH in a manner almost identical with the fraction that is protonated in bulk solution. The protonated compound exists almost completely in the hydrated form (gem-diol) in the interface just as it does in solution. At a given pH, the fraction protonated on the surface increases as …

Influence Of Wind And Windbreaks On Local Dispersal Of Insects, Judith Pasek

Judith E Pasek

Insect dispersal is affected by the wind and as a result, influenced by the presence of windbreaks. Wind reductions, microclimate modifications and vegetative diversity, influence insect distribution in sheltered areas.

Wingless insects and very small insects generally depend on air currents to carry them to new sites, but they tend to settle in areas with low windspeeds. It is often more advantageous for a flying insect to remain within its boundary layer where windspeeds are lower than the insect's flight speed. Flying insects tend to accumulate in areas of reduced windspeed where they have greater control of flight; however, distribution …

Correlated Muscle And Nerve Development In The Bullfrog Cutaneous Pectoris, Diana Linden, Michael Letinsky

Diana Linden

The development of the cutaneous pectoris muscle was studied and compared with the differentiation of its peripheral nerve in bullfrog (Rana catesbeiana) tadpoles and frogs by light and electron microscopic techniques. This muscle preparation was chosen for this study because it possesses a number of advantages for (and has become a model system for) the study of correlated nerve-muscle development. At the earliest stage examined (stage XI) the presumptive muscle did not contain any contractile or morphologically distinguishable myotubes, but was contacted by the well-defined cutaneous pectoris nerve trunk. Myotubes were present at stage XII, the same time that nerve-associated …

Stressors In The Learned Helplessness Paradigm: Effects On Body Weight And Conditioned Taste Aversion In Rats., Clinton Chapman, Nancy Dess, John Garcia, Jeffrey Raizer

Clinton D Chapman

In Exp 1, 44 male rats drank saccharin or a control solution, followed by 100 inescapable shocks or simple restraint. Ss were weighed daily and were tested for saccharin aversion 2 days after the stress session. Shocked Ss gained less weight than restrained controls. Saccharin aversion was apparent only among Ss that had consumed saccharin before the stress session. In Exp 2, 72 Ss drank saccharin solution, followed by shock, restraint, or no treatment. Half of each group was injected with saline; the other half was injected with lithium chloride. Shock reduced body weight relative to restraint or no treatment …

Motivation And Tort Law: Acting For Economic Gain As A Suspect Motive, Martin A. Kotler

Martin A. Kotler

Traditionally, tort scholars had claimed that the motives underlying a tortfeasor’s decision to act were largely irrelevant. This Article challenges that view by showing the recurring importance of motive. Specifically, whether the actor is perceived to have been motivated by a desire for personal economic gain or, conversely, motivated by altruism correlates closely with the development of tort doctrine imposing liability on the former and immunizing the latter.

The observation that the economically motivated actor has been disfavored historically contradicts much of the descriptive and normative law and economics literature which argued that wealth maximizing behavior was and should be …
