Short fiber reinforced thermoplastics (SFT) are extensively used due to their excellent mechanical properties and low processing costs. Long fiber reinforced thermoplastics (LFT) show an even more interesting property profile and are increasingly used for structural parts. However, their processing...
This study suggests a stochastic Bayesian approach for calibrating and validating morphodynamic sediment transport models and for quantifying parametric uncertainties in order to alleviate limitations of conventional (manual, deterministic) calibration procedures. The applicability of our method is shown f...
Chirale azyklische tertiäre Allylalkohole sind bedeutende Synthesebausteine, deren enantioselektive Synthese eine anspruchsvolle Aufgabe ist. Eine wesentliche Einschränkung bei katalytisch asymmetrischen 1,2-Additionen an Ketone ist die Enantioseitendifferenzierung durch sterische Unterscheidung beider Ketonreste. Um dieses Proble...
Chinese innovation is again flowing westwards, which is fomented by China’s Belt and Road Initiative. In this context, we study the international impact of innovations from specific countries. Based on panel data of patents from 27 countries over 17 years, we find that levels of...
For simulating reactive transport on aquifer scale, various modeling approaches have been proposed. They vary considerably in their computational demands and in the amount of data needed for their calibration. Typically, the more complex a model is, the more data are required to su...
Despite their excellent selectivities and activities, Mo‐and W‐based catalysts for olefin metathesis have not gained the same widespread use as Ru‐based systems, mainly due to their inherent air sensitivity. Herein, we describe the synthesis of air‐stable cationic‐at‐metal molybdenum and tungsten ...
We present herein anionic borate‐based bi‐mesoionic carbene compounds of the 1,2,3‐triazol‐4‐ylidene type that undergo C-N isomerization reactions. The isomerized compounds are excellent ligands for CoII centers. Strong agostic interactions with the “C-H”‐groups of the cyclohexyl substituents result in an ...
Die selektive Alkylierung von Pyrazolen ist eine Herausforderung in der Chemie und könnte die Synthese wichtiger Moleküle vereinfachen. In dieser Arbeit berichten wir über eine katalysatorgesteuerte Alkylierung von Pyrazolen durch eine cyclische Kaskadenreaktion mit zwei Enzymen. In diesem enzymatischen...
Single‐crystalline materials of Li[H2N3C3O3]·1.75 H2O and Mg[H2N3C3O3]2·8 H2O were obtained by dissolving stoichiometric amounts of the respective carbonates with cyanuric acid in boiling water followed by gentle evaporation of excess water after cooling to room temperature. Even though both of t...
Elementary building blocks for quantum repeaters based on fiber channels and memory stations are analyzed. Implementations are considered for three different physical platforms, for which suitable components are available: quantum dots, trapped atoms and ions, and color centers in diamond. The...
Photosensitizing units have already been applied to enable light‐driven catalytic reduction of CO2 with mononuclear rhenium complexes. However, dinuclear catalytic systems that are able to activate CO2 in a cooperative bimetallic fashion have only rarely been combined with photosensitizers. We he...
The dual iteration was introduced in a conference paper in 1997 by Iwasaki as an iterative and heuristic procedure for the challenging and non‐convex design of static output‐feedback controllers. We recall in detail its essential ingredients and go beyond the work of Iwasaki by...
The product μ‐bcqb from the reaction between p‐phenylenediamine and two equivalents of camphorquinone has been used as a potentially conjugated molecular bridge between two complex fragments [Cu(dppf)]+, dppf=1,1‘‐bis(diphenylphosphino)ferrocene, to yield 12+, and between two [Ru(bpy)2]2+ moieties, resulting in...
In this paper, a fluidic capacitive inclination sensor is presented and compared to three types of silicon-based microelectromechanical system (MEMS) accelerometers. MEMS accelerometers are commonly used for tilt measurement. They can only be manufactured by large companies with clean-room technology&...
The measurement and quantification of glucose concentrations is a field of major interest, whether motivated by potential clinical applications or as a prime example of biosensing in basic research. In recent years, optical sensing methods have emerged as promising glucose measurement techni...
Der Wandel des Konsumverhaltens und disruptive Geschäftsmodelle im Sinne von Business-to-User führen zu einem Wettbewerb um den Kundennutzen. Die Produktion befindet sich in einem Wandel hin zu einer nutzenzentrierten Produktion in einem Wettbewerb, der heute zusätzlich aus mehreren kleineren und ...
Hierarchical speed-up techniques have proven to be very effective in solving pathfinding problems in street networks, especially the shortest path problem. One of the most prominent hierarchical approaches is the Contraction Hierarchies algorithm. Another important pathfinding problem is the bottlenec...
Social media platforms such as Twitter have become important communication channels for politicians to interact with the electorate and communicate their stances on policy issues. In contrast to party manifestos, which lay out curated, compromised positions, the full range of positions withi...
