Wet-Chemically Prepared Porphyrin Layers on Rutile TiO2(110)
Porphyrins are large organic molecules that are interesting for different applications, such as photovoltaic cells, gas sensors, or in catalysis. For many of these applications, the interactions between adsorbed molecules and surfaces play a crucial role. Studies of porphyrins on surfaces typically fall into one of two groups: (1) evaporation onto well-defined single-crystal surfaces under well-controlled ultrahigh vacuum conditions or (2) more application-oriented wet chemical deposition onto less well-defined high surface area surfaces under ambient conditions. In this study, we will investigate the wet chemical deposition of 5-(monocarboxyphenyl)-10,15,20-triphenylporphyrin (MCTPP) on well-defined rutile TiO2 (110) single crystals under ambient conditions. Prior to deposition, the TiO2(110) crystals were also cleaned wet-chemically under ambient conditions, meaning none of the preparation steps were done in ultrahigh vacuum. However, after each preparation step, the surfaces were characterized in ultrahigh vacuum with X-ray photoelectron spectroscopy (XPS) and the result was compared with porphyrin layers prepared in ultrahigh vacuum (UHV) by evaporation. The differences of both preparations when exposed to zinc ion solutions will also be discussed.Fil: Wechsler, Daniel. Universitat Erlangen-Nuremberg; AlemaniaFil: FernĂĄndez, Cynthia Carolina.

Generator-collector voltammetry at dual-plate gold-gold microtrench electrodes as diagnostic tool in ionic liquids
Ionic liquids provide high viscosity solvent environments with interesting voltammetric characteristics and new electrochemical mechanisms. Here, a gold-gold dual-plate microtrench electrode is employed in generator-collector mode to enhance viscosity-limited currents in ionic liquids due to fast feedback within small inter-electrode gaps (5â
ÎŒm inter-electrode gap, 27â
ÎŒm microtrench depth) and to provide a mechanistic diagnosis tool. Three redox systems in the ionic liquid BMIm+BF4â are investigated: (i) ferrocene oxidation, (ii) oxygen reduction, and (iii) 2-phenyl-naphthyl-1,4-dione reduction. Both transient and steady state voltammetric responses are compared. Asymmetric diffusion processes, reaction intermediates, and solubility changes in the ionic liquid are revealed.A. J. G and F.

Ionic liquids at electrified interfaces
Until recently, âroom-temperatureâ (<100â150 °C) liquid-state electrochemistry was mostly electrochemistry of diluted electrolytes(1)â(4) where dissolved salt ions were surrounded by a considerable amount of solvent molecules. Highly concentrated liquid electrolytes were mostly considered in the narrow (albeit important) niche of high-temperature electrochemistry of molten inorganic salts(5-9) and in the even narrower niche of âfirst-generationâ room temperature ionic liquids, RTILs (such as chloro-aluminates and alkylammonium nitrates).(10-14) The situation has changed dramatically in the 2000s after the discovery of new moisture- and temperature-stable RTILs.(15, 16) These days, the âlater generationâ RTILs attracted wide attention within the electrochemical community.(17-31) Indeed, RTILs, as a class of compounds, possess a unique combination of properties (high charge density, electrochemical stability, low/negligible volatility, tunable polarity, etc.) that make them very attractive substances from fundamental and application points of view.(32-38) Most importantly, they can mix with each other in âcocktailsâ of oneâs choice to acquire the desired properties (e.g., wider temperature range of the liquid phase(39, 40)) and can serve as almost âuniversalâ solvents.(37, 41, 42) It is worth noting here one of the advantages of RTILs as compared to their high-temperature molten salt (HTMS)(43) âsister-systemsâ.(44) In RTILs the dissolved molecules are not imbedded in a harsh high temperature environment which could be destructive for many classes of fragile (organic) molecules
O acento musical secundĂĄrio dos properispĂŽmenos e dos proparoxĂtonos na SĂ©tima NemĂ©ia (um argumento da teoria acentual)
In this paper, a detaleid analysis of Pindar's Nemean 7 discusses forms and possibilities of musical accent in the ancient greek accentuation. The main focus is contibute to debate about the pressupposed homology between melodic moviment and musical accent.Neste artigo, a partir da SĂ©tima NemĂ©ia de PĂndaro, sĂŁo analisadas as possibilidades de acento musical e suas formas de registro linguĂstico. O que estĂĄ em jogo Ă© discutir a pressuposta homologia entre movimento melĂłdico e acento musica

Untersuchungen zur selektiven Futteraufnahme von Huehnern bei Naehr- und Wirkstoffmangel
Keine Praeferenz fuer Trogposition (links oder rechts). Nahrungswahl wird mehr durch Lernen als durch inneren Antrieb oder Instinkt verursacht. Fuer Methionin und Vitamin B6 wird ein spezifischer Appetit erst nach der Sammlung von Erfahrungen mit der Mangelration festgestellt. Nur im Zinkversuch erschien eine Praeferenz bevor irgendein postingestionaler Effekt auftrat. Die bekanntesten Theorien zur Regulation der Futteraufnahme, ebenso wie die Beteiligung der Sinnesorgane bei der Futterwahl, werden erlaeutertAvailable from: Technische Univ. Muenchen (Germay, F.R.).
