However, detection of highly diluted concentrations and small molecules is still challenging. It is shown here that in contrast to continuous gold films, gold nanohole arrays can significantly improve the performance of SPR devices in angle-dependent measurement mode, as a signal amplification arises from localized surface plasmons at the nanostructures. This leads consequently to an increased sensing capability of molecules bound to the nanohole array surface. Furthermore, a reduced graphene oxide (rGO) sensor surface was layered over the nanohole array. Reduced graphene oxide is a 2D nanomaterial consisting of sp2-hybridized carbon atoms and is an attractive receptor surface for SPR as it omits any bulk phase and therefore allows fast response times. In fact, it was found that nanohole arrays demonstrated a higher shift in the resonance angle of 250-380\% compared to a continuous gold film. At the same time the nanohole array structure as characterized by its diameter-to-periodicity ratio had minimal influence on the binding capacity of the sensor surface. As a simple and environmentally highly relevant model, binding of the plasticizer diethyl phthalate (DEP) via π-stacking was monitored on the rGO gold nanohole array realizing a limit of detection of as low as 20 nM. The concentration-dependent signal change was studied with the best performing rGO-modified nanohole arrays. Compared to continuous gold films a diameter-to-periodicity ratio (D/P) of 0.43 lead to a 12-fold signal enhancement. Finally, the effect of environmental waters on the sensor was evaluated using samples from sea, lake and river waters spiked with analytically relevant amounts of DEP during which significant changes in the SPR signal are observed. It is expected that this concept can be successfully transferred to enhance the sensitivity in SPR sensors.}, language = {en} } @inproceedings{HoellerZeitler, author = {H{\"o}ller, Christoph and Zeitler, Berndt}, title = {Playing ball with transients on the force plate and on the reception plate}, series = {Noise control for a better environment.

The narratives are thematically analysed, whereas two themes regarding participants' motivation for establishing relationship despite differences and long-term sustaining of the relationship are described in the chapter. Preliminary findings nuance the phenomenon of love in academic exchanges, invoking concepts such as educational homogamy, balancing independence and togetherness, diversities of connectivities intersecting social media and intimacies. Furthermore, the significant others' support and opposition of these couples' love dynamics are covered, along with considerations linked to the concept of the emotional availability (Saunders, Kraus, Barone \& Biringen, Frontiers in Psychology, 2015) based on Bowlby's attachment theory and the shared third (Benjamin, Psychoanalytic Quarterly, 73(1), 5-46, 2004). Lastly, 'good practices' for promoting the mental health and wellbeing of such academic exchange couples are delineated along with suggestions for relevant services for those experiencing psychosocial problems.

The goal of the proposed magnet system is to minimize the coil-current effect and to optimize the shielding at the same time. In the proposed design, a permanent magnet system with two gaps, each housing a coil, is employed to minimize the coil current effect, by reducing the linear coil-current dependence reported for the single air gap design by at least one order of magnitude. Both air gaps of the magnet are completely surrounded by high-permeability material, and hence the coils are shielded from outside magnetic fields and no magnetic field leaks outside of the magnet system. An example of the new magnet system is given and the analysis shows that the magnetic field in the air gap can be optimized to meet the requirement to be used in Kibble balances.}, language = {en} } @article{RothleitnerSchlamminger, author = {Rothleitner, Christian and Schlamminger, Stephan}, title = {Invited Review Article: Measurements of the Newtonian constant of gravitation, G}, series = {Review of Scientific Instruments}, volume = {88}, journal = {Review of Scientific Instruments}, number = {11}, publisher = {AIP Publishing}, doi = {10.1063/1.4994619}, abstract = {By many accounts, the Newtonian constant of gravitation G is the fundamental constant that is most difficult to measure accurately. Over the past three decades, more than a dozen precision measurements of this constant have been performed. However, the scatter of the data points is much larger than the uncertainties assigned to each individual measurement, yielding a Birge ratio of about five. Today, G is known with a relative standard uncertainty of 4.7 x 10(-5), which is several orders of magnitudes greater than the relative uncertainties of other fundamental constants. In this article, various methods to measure G are discussed. Alarge array of different instruments ranging from the simple torsion balance to the sophisticated atom interferometer can be used to determine G. Some instruments, such as the torsion balance can be used in several different ways. In this article, the advantages and disadvantages of different instruments as well as different methods are discussed. A narrative arc from the historical beginnings of the different methods to their modern implementation is given.

With introduction of the concept 'hybrid warfare' a new systematic element was established in scientific research. Nevertheless, the concept is discussed rather controversially and often its scientific value is questioned. Most of the literature describes the empirical phenomena of hybrid warfare, but does not provide a theoretical based argumentation. This paper addresses the neglected aspect of systemic analysis by focusing on vulnerability of modern societies and outlines a concept based on the theoretical idea of safety, security and certainty to grasp the underlying driving factors of new forms and methods in asymmetric conflicts. The analysis presented here shows that sociology and system engineering have already developed valuable conceptual definitions of safety, security and certainty that can be used for the analysis of asymmetric conflicts. The missing link, closed by this paper, was an interdisciplinary approach to integrate these concepts into an analysis framework. The findings indicated that the new forms of asymmetric conflicts can be understood as a concise and precise analysis of systemic weaknesses of nation states and their societies. Still, Western European nations focus their security policy mainly on past challenges of war and peace. Therefore, societies of these nations remain highly vulnerable to safety threats and uncertainty. The presented theoretical framework supported this result and should, therefore, be of value to analysts and scientists alike aiming to identify the underlying systemic factors of innovative asymmetric conflict.}, language = {en} } @incollection{Schliermann, author = {Schliermann, Rainer}, title = {Fußball}, series = {Leitfaden Physiotherapie in der Neurologie.
