abstract = {{In research, pedagogical content knowledge (PCK) is considered as an important aspect of teachers’ professional competence. However, there is no standardized definition concerning the internal structure of this concept, especially in science subjects such as physics. Therefore, results of different empirical studies measuring PCK are difficult to compare. Moreover, there is no study that can report on correlations between various aspects of PCK. Against this background, different conceptualizations and theoretical considerations of PCK have been consulted and compared. Based on these analyses, a comprehensive model of prospective physics teachers’ PCK and a related test instrument (in the form of a pen-and-paper test) have been developed. Its purpose is to enlighten the correlations between certain aspects of PCK as well as between PCK and other areas of knowledge (e.g. content knowledge). To validate the test instrument and the underlying PCK model, a think aloud study with 15 probands was conducted. We focused on the knowledge areas that the probands referred to while answering the items. With these data, indications of the validity of the underlying model could be identified. Furthermore, the test instrument was piloted with a sample of 216 prospective physics teachers.

abstract = {{
We examine for the first time how chemically and thermally stable gold nanoparticles (NPs), prepared by a silane conjugation approach, affect both the thermal and the electro-optical properties of a nematic liquid crystal (LC), when doped at concentrations ranging from 0.25 to 7.5 wt%. We find that the octadecylsilane-conjugated gold NPs stabilize both the enantiotropic nematic and the monotropic smectic-A phases of the LC host with a maximum stabilization of 2
°
C for the nematic and 3.5
°
C for the smectic-A phases for the mixture containing 1 wt% of the silanized particles. The same mixture shows the lowest values for the Fréedericksz transition threshold voltage and the highest value for the dielectric anisotropy. Generally, all NP-containing mixtures, except mixtures with NP concentrations exceeding 5 wt%, reduce the threshold voltage, increase the dielectric anisotropy and reduce both rise and decay time; the latter particularly at temperatures at least 10
°
C below the isotropic–nematic phase transition on cooling.
