    Description: Der Beitrag beschreibt die Modifikation der elektrochemischen und mechanischen Eigenschaften von mit Kohlenstoffasern verstärktem Reinaluminium (C/Al-Verbund) aufgrund der Anwendung zweier verschiedener Faserbeschichtungen. Es werden potentiodynamische Korrosionsuntersuchungen, Transmissionselektronenmikroskopie, Biegetests und Einzelfaser-'push in'-Tests durchgeführt. Die potentiodynamischen Korrosionstests erfolgen in 3.5%iger NaCl-Lösung. Die Ergebnisse belegen eine drastische Verschlechterung der Korrosionsresistenz aufgrund der Faserbeschichtung mit pyrolytischem Kohlenstoff. Eine Beschichtung der Fasern mit SiC verbessert die Korrosionsbeständigkeit der Verbunde. Allerdings werden die mechanischen Eigenschaften durch die SiC-Schicht beeinträchtigt. Die pyrolytische Kohlenstoffschicht führt zur verstärkten Energiedissipation durch 'stick-slip' Effekte an der Grenzläche während der Belastung. Die Abscheidung von Mehrfachschichten aus pyrolytischen Kohlenstoff und SiC könnte schließlich in einer Verbesserung der elektrochemischen Eigenschaften und optimierten mechanischen Kennwerten resultieren.

    Description: Design, manufacturing, calibration, and basic characterization of a microelectromechanical systems (MEMS) wall hot wire sensor on a flexible polyimide substrate are presented. A configuration exhibiting bond pads on the top side of the foil, as well as an improved setup featuring a through-foil metallization and bottom side bond pads were established. Both sensor designs make use of a highly sensitive nickel thin-film resistor spanning a reactive ion etched cavity in a polyimide substrate. The polyimide base material enables the sensor to be adapted to curved aerodynamic surfaces, e.g., airfoils and turbine blades. A mismatch of curvature of aerodynamic surface and silicon sensor surface, as observed with previously presented MEMS hot-wire anemometers is avoided. The combination of polyimide's low thermal conductivity and a cavity featuring FEM-optimized dimensions accounts for a very low-power consumption (〈25 mW). Fluctuations in wall shear stress up to 85 kHz can be resolved in constant-temperature mode. An average sensitivity of 0.166 V/(N/m〈sup〉2〈/sup〉) is achieved in a wall shear stress range from 0 to 0.72 N/m〈sup〉2〈/sup〉. The specifically designed through-foil metallization process allows for electrical contacts to be positioned on the backside of the substrate, thus effectively minimizing aerodynamic disturbances.

    Description: Micromachined wall hot-wire sensors composed of a highly sensitive, nickel, thin-film resistor spanning an air-filled cavity in a mechanically flexible substrate are presented. Cavity design and sensor materials are optimized to reduce thermal losses, thus enabling measurement of high-frequency fluctuations in fluid flows. Successfully realized sensors featuring wire widths of 2 and 5 [micro]m, wire lengths from 400 to 2000 [micro]m, and various cavity dimensions were characterized in wind-tunnel experiments. Static sensor calibration, cutoff frequency determination using a sine sweep, and recording of angular characteristics were conducted at wall shear stresses of up to 1 N/[m.sup.2], obtained at 20 m/s freestream velocity in an open wind tunnel on a flat plate with fully developed turbulent flow. An overheat ratio of 1.8 was used for hours without thermal failure of the sensors, and a maximum cutoff frequency in still air of 73 kHz was obtained. The highest average sensitivity of 0.196 V/(N/[m.sup.2]) was recorded for a sensor of 5-[micro]m wire width and a length-to-width ratio of 400 in a wall shear stress range from 0 to 1 N/[m.sup.2] with a power consumption of less than 30 mW.

    Description: ► The sorption of a branched nonylphenol isomer (NP111) on humic acids was investigated by a dialysis technique. ► Humic acids were characterized by solid-state 13C DP/MAS NMR spectroscopy. ► A relationship between the organic carbon-normalized sorption coefficients of NP111 and the aliphaticity of humic acids was established. By using dialysis equilibrium experiments, the sorption of a branched nonylphenol isomer [4-(1-ethyl-1,3-dimethylpentyl)-phenol] (NP111) on various humic acids (HAs) isolated from river sediments and two reference HAs was studied. The HAs were characterized by solid-state 13C direct polarization/magic angle spinning nuclear magnetic resonance ( 13C DP/MAS NMR) spectroscopy. Sorption isotherms of NP111 on HAs were described by a linear model. The organic carbon-normalized sorption coefficient ( K OC) ranged from 2.3 × 10 3 to 1.5 × 10 4 L kg −1. Interestingly, a clear correlation between ...
