Twenty years of development of dual and multi‐selector models in capillary electrophoresis: A review

Electrophoresis (2014)

Ludmila Müllerová Pavel Dubský Bohuslav Gaš

It has been 20 years since Lurie et al. first published their model of electromigration of an analyte under simultaneous interaction with two cyclodextrins as chiral selectors. Since then, the theory of (enantio)separation in dual and complex mixtures of (chiral) selectors is well understood. In spite of this, a trial-and-error approach still prevails in analytical practice. Such a situation is likely caused by the fact that the entire theory is spread over numerous papers and the relations between various models are not always clear. The present review condenses the theory for the first time. Available mathematical models and feasible practical approaches are summarized and their advantages and limitations discussed.

3-dimensional optical model for thin film silicon solar cells

3rd World Conference onPhotovoltaic Energy Conversion, 2003. Proceedings of (2003)

J. Špringer A. Poruba Ludmila Müllerová M. Vaněček W. Reetz

This paper addresses optical effects in small area thin film silicon p-i-n solar cells deposited on a glass/TCO substrate. An existing one-dimensional model was extended to three dimensions to include the effect of substrate glass thickness and lateral solar cell area. With its help we can model real laboratory cells where the cell dimensions are comparable to the glass thickness. For a quantitative evaluation we compare the external quantum efficiency of an infinitely large solar cell with small area cells. Here the modeling results show increasing differences with increasing glass thickness, decreasing cell area and improving light scattering properties of the TCO. This is explained by internal light trapping in the glass substrate, which causes loss or gain of light intensity absorbed in the cell area. Neglecting such effects can lead to about 11% error in short circuit current density calculated from quantum efficiency measurements.

Absorption loss at nanorough silver back reflector of thin-film silicon solar cells

Journal of Applied Physics (2004)

J. Špringer A. Poruba Ludmila Müllerová M. Vaněček O. Kluth

Absorption losses at a nanorough silver back reflector of a solar cell were measured with high accuracy by photothermal deflection spectroscopy. Roughness was characterized by atomic force microscopy. The observed increase of absorption, compared to the smooth silver, was explained by the surface plasmon absorption. Two series of silver back reflectors (one covered with thin ZnO layer) were investigated and their absorption related to surface morphology.

Determination of effective mobilities of EOF markers in BGE containing sulfated β‐cyclodextrin by a two‐detector method

Electrophoresis (2012)

Ludmila Müllerová Pavel Dubský Jana Svobodová Bohuslav Gaš

A neutral marker of the EOF can gain a nonzero effective mobility because of its possible interaction with a charged complexing agent, such as a chiral selector in CE . We determined effective mobilities of four compounds often used as EOF markers (dimethyl sulfoxide, mesityl oxide, nitromethane, and thiourea) in the BGE ‐containing sulfated β‐CD (60 g/L). All the compounds studied were measurably mobilized by their interaction with the selector. The highest effective mobility (–3.0·10 −9 m 2 s −1 V −1 ) was observed for thiourea and the lowest (–1.5·10 −9 m 2 s −1 V −1 ) for dimethyl sulfoxide and nitromethane. The mobilities were determined by a new two‐detector pressure mobilization method (2d method), which we propose, and the results were confirmed by standard CE measurements. In the 2d method, one marker zone is situated in the BGE containing the charged selector, while the second marker zone is surrounded with a selector‐free BGE , which prevents its complexation. The initial distance between the two marker zones equals the capillary length from the inlet to the first detector. After a brief voltage application, the final distance between the marker zones is determined based on known capillary length from the first to the second detector. The difference between these two distances determines the effective mobility.
