The inevitable presence of transition metals in industrial processes implies the ambition of developing a proper analytical technique for their adequate monitoring. Most of these elements, especially lead and cadmium, are acutely toxic for biological organisms. Quantitative determination of these metals at low activity levels in different environmental and industrial samples is therefore a vital task. A promising approach to achieve an at-side or on-line monitoring on a miniaturized and cost efficient way is the combination of a common potentiometric sensor array with heavy metal-sensitive thin-film materials, like chalcogenide glasses and polymeric materials, respectively.}, language = {en} } @article{GuoSekiMiyamotoetal.2014, author = {Guo, Yuanyuan and Seki, Kosuke and Miyamoto, Ko-ichiro and Wagner, Torsten and Sch{\"o}ning, Michael Josef and Yoshinobu, Tatsuo}, title = {Novel photoexcitation method for light-addressable potentiometric sensor with higher spatial resolution}, series = {Applied physics express : APEX}, volume = {7}, journal = {Applied physics express : APEX}, number = {6}, publisher = {IOP}, address = {Bristol}, issn = {1882-0786 (E-Journa); 1882-0778 (Print)}, doi = {10.7567/APEX.7.067301}, pages = {067301-4}, year = {2014}, abstract = {A novel photoexcitation method for the light-addressable potentiometric sensor (LAPS) is proposed to achieve a higher spatial resolution of chemical images. The proposed method employs a combined light source that consists of a modulated light probe, which generates the alternating photocurrent signal, and a ring of constant illumination surrounding it. The constant illumination generates a sheath of carriers with increased concentration which suppresses the spread of photocarriers by enhanced recombination. A device simulation was carried out to verify the effect of constant illumination on the spatial resolution, which demonstrated that a higher spatial resolution can be obtained.}, language = {en} } @article{SchoeningMalkocThustetal.2000, author = {Sch{\"o}ning, Michael Josef and Malkoc, {\"U}. and Thust, M. and Steffen, A. and Kordos, P. and L{\"u}th, H.}, title = {Novel electrochemical sensors with structured and porous semiconductor/insulator capacitors}, series = {Sensors and Actuators B. 65 (2000), H. 1-3}, journal = {Sensors and Actuators B. 65 (2000), H. 1-3}, isbn = {0925-4005}, pages = {288 -- 290}, year = {2000}, language = {en} } @article{SchoeningMalkocThustetal.1998, author = {Sch{\"o}ning, Michael Josef and Malkoc, {\"U}. and Thust, M. and Steffen, A. and Kordos, P. and L{\"u}th, H.}, title = {Novel electrochemical sensors with structured and porous semiconductor/insulator capacitors}, series = {Proceedings of the Seventh International Meeting on Chemical Sensors : 27 - 30 July, 1998, Beijing, P.

In dense multiciliated carpets, cilia were shown to exhibit a remarkable coordination of their beat in the form of traveling metachronal waves, a phenomenon which supposedly enhances fluid transport. Yet, how cilia coordinate their regular beat in multiciliated epithelia to move fluids remains insufficiently understood, particularly due to lack of rigorous quantification. We combine experiments, novel analysis tools, and theory to address this knowledge gap. To investigate collective dynamics of cilia, we studied zebrafish multiciliated epithelia in the nose and the brain. We focused mainly on the zebrafish nose, due to its conserved properties with other ciliated tissues and its superior accessibility for non-invasive imaging. We revealed that cilia are synchronized only locally and that the size of local synchronization domains increases with the viscosity of the surrounding medium. Even though synchronization is local only, we observed global patterns of traveling metachronal waves across the zebrafish multiciliated epithelium. Intriguingly, these global wave direction patterns are conserved across individual fish, but different for left and right noses, unveiling a chiral asymmetry of metachronal coordination. To understand the implications of synchronization for fluid pumping, we used a computational model of a regular array of cilia. We found that local metachronal synchronization prevents steric collisions, i.e., cilia colliding with each other, and improves fluid pumping in dense cilia carpets, but hardly affects the direction of fluid flow. In conclusion, we show that local synchronization together with tissue-scale cilia alignment coincide and generate metachronal wave patterns in multiciliated epithelia, which enhance their physiological function of fluid pumping.}, language = {en} } @article{Pawelke2000, author = {Pawelke, Siegfried}, title = {Note on Jackson and Bernstein type approximation theorems in the case of approximation by algebraic polynomial in the spaces L and C}, series = {Studia Scientiarum Mathematicarum Hungarica. 36 (2000), H. 3-4}, journal = {Studia Scientiarum Mathematicarum Hungarica. 36 (2000), H. 3-4}, isbn = {0081-6906}, pages = {353 -- 358}, year = {2000}, language = {en} }
