In this study, beta-zeolite-based adsorbent systems were examined, and their properties were compared to organic resins. Batch adsorption experiments were conducted with synthetic solutions of major polyphenols. Adsorption isotherms and desorption characteristics of individual adsorbent were determined based on these results. Maximum adsorption capacities were calculated using the Langmuir model. For example, the zeolites had capacities up to 203.2 mg/g for ferulic acid. To extend these results to a complex system, additional experiments were performed on rapeseed meal and wheat seed extracts as representative renewable resources. HPLC analysis showed that with 7.5\% w/v, which is regarded as the optimum amount of zeolites, zeolites A and B could bind 100\% of the major polyphenols as well as release polyphenols at high yields. Additionally, regeneration experiments were performed with isopropyl alcohol at 99°C to evaluate how zeolites regenerate under mild conditions. The results showed only a negligible loss of adsorption capacity and no loss of desorption capacity. In summary, it was concluded that beta-zeolites were promising adsorbents for developing new processes to isolate polyphenols from renewable resources.}, language = {en} } @article{Stulpe2013, author = {Stulpe, Werner}, title = {From the attempt of certain classical reformulations of quantum mechanics to quasi-probability representations}, series = {Journal of mathematical physics}, volume = {55}, journal = {Journal of mathematical physics}, number = {1}, publisher = {American Institute of Physics}, issn = {1089-7658 (Online)}, doi = {10.1063/1.4861939}, pages = {25 Seiten}, year = {2013}, abstract = {The concept of an injective affine embedding of the quantum states into a set of classical states, i.e., into the set of the probability measures on some measurable space, as well as its relation to statistically complete observables is revisited, and its limitation in view of a classical reformulation of the statistical scheme of quantum mechanics is discussed. In particular, on the basis of a theorem concerning a non-denseness property of a set of coexistent effects, it is shown that an injective classical embedding of the quantum states cannot be supplemented by an at least approximate classical description of the quantum mechanical effects.

In this work, an impedimetric sensor has been applied for real-time and in situ monitoring of degradation processes of biopolymers. The sensor consists of two platinum thin-film electrodes covered by a polymer film to be studied. The benchmark biomedical polymer poly(D,L-lactic acid) (PDLLA) was used as a model system. PDLLA films were deposited on the sensor structure from a polymer solution by using the spin-coating method. The degradation kinetics of PDLLA films have been studied in alkaline solutions of pH 9 and 12 by means of an impedance spectroscopy (IS) method. Any changes in a polymer capacitance/resistance induced by water uptake and/or polymer degradation will modulate the global impedance of the polymer-covered sensor that can be used as an indicator of the polymer degradation. The degradation rate can be evaluated from the time-dependent impedance spectra. As expected, a faster degradation has been observed for PDLLA films exposed to pH 12 solution.}, language = {en} } @article{SchneiderSchneiderKinderetal.2013, author = {Schneider, Bettina and Schneider, Wilhelm and Kinder, Stephanie and Meinhardt, Kerstin}, title = {Die Fallstudie: Besteuerung außerordentlicher Eink{\"u}nfte bei der Einkommensteuer}, series = {Das Wirtschaftsstudium : wisu ; Zeitschrift f{\"u}r Ausbildung, Pr{\"u}fung, Berufseinstieg und Fortbildung}, volume = {42}, journal = {Das Wirtschaftsstudium : wisu ; Zeitschrift f{\"u}r Ausbildung, Pr{\"u}fung, Berufseinstieg und Fortbildung}, number = {11}, publisher = {Lange}, address = {D{\"u}sseldorf}, issn = {0340-3084}, pages = {1432 -- 1434}, year = {2013}, language = {de} } @article{SchneiderSchneider2013, author = {Schneider, Bettina and Schneider, Wilhelm}, title = {Rechnungslegung nach IFRS im Vergleich zum HGB}, series = {Das Wirtschaftsstudium : wisu ; Zeitschrift f{\"u}r Ausbildung, Examen, Berufseinstieg und Fortbildung}, journal = {Das Wirtschaftsstudium : wisu ; Zeitschrift f{\"u}r Ausbildung, Examen, Berufseinstieg und Fortbildung}, publisher = {Lange}, address = {D{\"u}sseldorf}, issn = {0340-3084}, pages = {536 -- 541}, year = {2013}, language = {de} }
