Publisher's Version תקציר The formation of flexible self-assembled monolayers (SAMs) in which an external trigger modifies the geometry of surface-anchored molecules is essential for the development of functional materials with tunable properties. In this work we
demonstrate that NO2-functionalized N-heterocyclic carbene molecules (NHCs), which were anchored on Au (111) surface, change their orientation from tilted into a flat-lying position following trigger-induced reduction of their nitro groups. DFT calculations identified that the energetic driving force for reorientation was the lower steric hindrance and stronger interactions between the chemically-reduced NHCs and the Au surface. The trigger-induced changes in the NHCs’ anchoring geometry and chemical functionality modified the work function and the hydrophobicity of the NHCs-decorated Au surface, demonstrating the impact of chemically-tunable NHCs-based SAM on the properties of the metal surface.

Past research has demonstrated that many individuals are not well equipped to make financial decisions and hence depend greatly on the flow and quality of financial information. Various governments are implementing reforms aimed at improving the quality of pension financial communication. Certain countries are requiring a move to short-form pension reporting, and some are requiring digital reporting instead of (or in some cases, in addition to) paper reporting. In a series of experiments, we show that the ability to locate information in financial reports is sensitive to the length of the report and to the communication form.
Researchers aspire to capture various aspects of dialogue emerging in classroom interactions using systematic analyses. Recent years have seen increasing demand for ‘mixed methods’ approaches that offer more information. These approaches build on converging theoretical clarity and understandings, technological tools and better communication among scholars interested in classroom discussions. In this chapter, we showcase several different ways of mixing methods and enriching the information from classroom observations. The first is combining analytic tools to capture and integrate qualitative and quantitative data, and it suggests using network models to interpret the results of dialogue coding. The second suggests examining more than one grain size of analytic unit (e.g., turn, episode and lesson), or coding transcribed interaction in a top-down or bottom-up manner or both. The third approach suggests synthesising across different frameworks of analysis, to understand disciplinary and multimodal dialogues. Sociocultural discourse analysis and epistemic network analysis illustrate multiple approaches.
