Multidimensional separation techniques play an increasingly important role in separation science, especially for the analysis of complex samples such as proteins. The combination of reversed-phase liquid chromatography in the nanoscale and CZE is especially beneficial due to their nearly orthogonal separation mechanism and well-suited geometries/dimensions. Here, a heart-cut nano-LC-CZE-MS setup was developed utilizing for the first time a mechanical 4-port valve as LC-CE interface. A model protein mixture containing four different protein species was first separated by nano LC followed by a heart-cut transfer of individual LC peaks and subsequent CZE-MS analysis. In the CZE dimension, various glycoforms of one protein species were separated. Improved separation capabilities were achieved compared to the 1D methods, which was exemplarily shown for ribonuclease B and its different glycosylated forms. LODs in the lower μg/mL range were determined, which are considerably lower compared to traditional CZE-MS. In addition, this study represents the first application of an LC-CE-MS system for intact protein analysis. The nano-LC-CZE-MS system is expected to be applicable to various other analytical challenges.
A ferromagnetic barrier thinner than the coherence length in high-temperature superconductors is realized in the multilayers of YBa2Cu3O7-δ and La0.67Ca0.33MnO3. We used epitaxial growth of YBCO on ⟨110⟩ SrTiO3 substrates by pulsed laser deposition to prepare thin superconducting films with copper oxide planes oriented at an angle to the substrate surface. Subsequent deposition of LCMO and finally a second YBCO layer produces a superconductor/ferromagnet/superconductor trilayer containing an ultrathin ferromagnetic barrier with sophisticated geometry at which the long axis of coherence length ovoid of YBCO is pointing across the LCMO ferromagnetic layer. A detailed characterization of this structure is achieved using high-resolution electron microscopy.

With the advent of modern communication media over the last decades, such as email, video conferencing, or instant messaging, a plethora of research has emerged that analyzes the association between communication media and negotiation processes and outcomes. This chapter reviews theoretical vantage points on communication media and negotiation and summarizes empirical findings from the last five decades. Specifically, the author focuses on media richness theory and the task/media fit hypothesis, grounding in communication, and media synchronicity theory as communication theoretical foundations that found traction in negotiation research. These theoretical vantage points are supplemented by a review of specific theoretical psychological aspects of communication media, the barrier effect and psychological distance theory. In the second part of the chapter, empirical evidence on communication media and negotiation is presented, derived from an extensive literature search of relevant peer-reviewed articles. The emphasis in this review of the empirical literature is on the communication medium as an independent variable. In other words, the author analyzes effects of communication media on the negotiation process (descriptive process parameters, economic reference points, negotiation behavior/tactics, individual psychological variables, assessment of the opponent) as well as economic (agreement, individual profit, joint profit, equality of agreement) and socio-emotional (satisfaction, future interaction, trust) outcomes. A succeeding subsection is devoted to communication medium choice in negotiation, a topic much less researched. The conclusion sums up the findings and sketches out some avenues for future research.
