The decarbonization of the industrial sector plays a crucial role in a successful energy transition. This transformation is very costly and complex, as many of the existing production processes and plants will have to be partially or completely replaced to reduce carbon dioxide (CO...
Enantiopure secondary alcohols are fundamental high‐value synthetic building blocks. One of the most attractive ways to get access to this compound class is the catalytic hydroboration. We describe a new concept for this reaction type that allowed for exceptional catalytic turnover numbers...
Finite elements with Allman's rotations provide good computational efficiency for explicit codes exhibiting less locking than linear elements and lower computational cost than quadratic finite elements. One way to further raise their efficiency is to increase the feasible time step or in...
Messenger RNA (mRNA) is emerging as an attractive biopolymer for therapy and vaccination. To become suitable for vaccination, mRNA is usually converted to a biomaterial, using cationic peptides, polymers or lipids. An alternative form of converting mRNA into a material is demonstrated t...
Antarctic sea ice formation in the Marginal Ice Zone (MIZ) and its mutual effects on ocean biology and chemistry is very sensitive to climate change. The formation of ’pancake’ ice floes and the coupled physical‐biogeochemical (P‐BGC) processes can be modeled by using the continuum...
Herein, we report the synthesis of a series of push–pull imines by considering cyclic diamino substituent at the C‐centre and fluoroaryl substituent at the N‐centre. This has been achieved by a selective aromatic nucleophilic substitution of different fluoroarenes by N‐H‐substituted N‐heterocycli...
A major goal for process and cell engineering in the biopharmaceutical industry is enhancing production through increasing volumetric and cellspecific productivities (CSP). Here, we present 50-deoxy-50-(methylthio)adenosine (MTA), the degradation product of S-(50-adenosyl)-L-methionine (SAM), as a highly attractive&...
A modeling approach for atomic‐resolution studies of sup‐ ported ionic liquid phase (SILP) catalytic systems in silica mesoporous confinement with surface hydroxyl and functional groups is proposed. First, a force field for the Ru‐based catalyst is developed. Second, its solvation behavior w...
Tissue engineering requires the precise positioning of mammalian cells and biomaterials on substrate surfaces or in preprocessed scaffolds. Although the development of 2D and 3D bioprinting technologies has made substantial progress in recent years, precise, cell‐friendly, easy to use, and fast...
1,2,3‐triazoles, the corresponding triazolium salts, and the resulting mesoionic carbenes (MICs) of the 1,2,3‐triazol‐5‐ylidene type are at the forefront of contemporary research. In this contribution, we present a comprehensive study involving eight triazoles, seventeen triazolium salts, two silver(i)‐ an...
Modern research methods produce large amounts of scientifically valuable data. Tools to process and analyze such data have advanced rapidly. Yet, access to large amounts of high‐quality data remains limited in many fields, including catalysis research. Implementing the concept of FAIR data...
Reaction of a phosphane‐decorated benzenedithiol (pbdtH2) with coinage metal salts furnished polynuclear complexes [M2(pbdtH)2] (M=AuI) or [cat][M5(pbdt)3] (cat=unipositive cation, M=AgI, CuI), which were characterized by analytical and spectroscopic techniques and single‐crystal X‐ray diffraction studies. Furthermore, a...
The efficacy of heterogeneous catalysis relies heavily on diffusion and distribution of reactants within catalyst supports. However, the presence of confinement, essential for reaction selectivity, drastically slows down molecular transport. Here, macro‐mesoporous silica inverse opal (SiO2-IO) films were u...
To meet climate change goals and respond to increased global urbanisation, the building industry needs to improve both its building technology and its design methods. Constrained urban environments and building stock extensions are challenges for standard timber construction. Co-design promises t...
Detailed knowledge of the flow characteristics, bubble movement, and mass transfer is a prerequisite for the proper design of multiphase bioreactors. Often, mechanistic spatiotemporal models and computational fluid dynamics, which intrinsically require computationally demanding analysis of local interfacial...
Bubble growth processes are highly influenced by the elongational viscosity of the blowing agent-loaded polymer melt. Therefore, the elongational viscosity is an important parameter for the development of new polymers for foaming applications, as well as for the prediction of bubble growth...
With the growing demand to perform increasingly complex computations such as image, audio or video processing or machine learning on mobile devices, energy consumption becomes a crucial factor for the lifetime and usability of these devices. A common way to reduce the amount of...
Diese Arbeit stellt vor, wie ein Video-Stream mit niedriger Latenz im Webbrowser implementiert werden kann, um eine Echtzeit-Interaktion zu ermöglichen. Dabei werden verschiedene Streaming-Technologien wie Motion JPEG (MJPEG), Web Real-Time Communication (WebRTC), HLS (HTTP Live Streaming) und DASH (Dynami...
Zentraler Gegenstand dieser Arbeit ist der Nachweis der Zuverlässigkeit von Systemen und die Planung der dazu notwendigen Tests. Selbst einfache Produkte können durch mehrere Ursachen und Mechanismen ausfallen und besitzen dazu meist mehrere Komponenten und Subsysteme. Diese Arbeit behandelt die ...
Wie können Städte als komplexe Systeme innovationsoffener und wandlungsfähiger für zukünftige Herausforderungen werden? Die Dissertation adressiert die Systematisierung von kooperativen Innovations- und Diffusionsprozessen zwischen Städten im globalen Kontext der urbanen Transformation und technologieoffenen Stadtentwicklung. ...
