In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots.}}, author = {{Killi, Naresh and Kumar, Amit and Nebhani, Leena and Obst, Franziska and Richter, Andreas and Reineke Matsudo, Bernhard and Zentgraf, Thomas and Kuckling, Dirk}}, issn = {{2470-1343}}, journal = {{ACS Omega}}, number = {{9}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction}}}, doi = {{10.1021/acsomega.5c09476}}, volume = {{11}}, year = {{2026}}, } @inproceedings{60666, abstract = {{Few principalities were as interwoven with European politics and as prone to dichotomous debate as the East Frisian Jever. At the mouth of the Weser and in the back of the Dutch republic, Jever conjoined the Western and Nordic struggles of the seventeenth century. It proved crucial during the French invasions of the Low Countries and it enabled Denmark-Norway to march on a wider front against Swedish possessions on the continent. When the Danish king in 1677 tried to add Jever to his Oldenburg titles, he was thus locked in a conflict between Spain and France regarding the overlordship over Jever. This revealed larger interests because Jever was connected to the Holy Roman Empire through feudal bonds with the Spanish Netherlands and the Burgundian Circle that unified these Netherlands. The presentation will show how the prima vista dichotomy of French or Spanish overlordship over Jever carried the real debate whether Jever – and thus the Spanish Netherlands – belonged to the Empire or not. In claiming the right to hand Jever to Denmark for an alliance, French Louis XIV not only severed the Spanish Netherlands from imperial support. He also disintegrated them. Spain therefore couldn’t accept foreign overlordship over Netherlandish fiefs and needed Jever to solicit Danish support against the French. Meanwhile, the Emperor fought the intrusion of France’s Réunion policy in the Empire whilst Brandeburg and Sweden meddled to manoeuvre Denmark within the ongoing Nordic struggle. The outcome of the debate (at the imperial Diet as well as the Danish court) would ultimately decide the margins within the Empire to choose alliances.

This study establishes a validated hierarchical methodology to predict tolerance-dependent failure behavior of SPR joints, progressing from coupon to sub-component scale through an integrated experimental–numerical approach. Five critical manufacturing tolerances, including rivet length (±0.5 mm), rivet head position (±0.3 mm), orthogonality deviation (2.8° and 5°), lateral offset (up to 1.2 mm), and flange overlap reduction (up to 7.5 mm), were investigated. Steel–steel joints exhibited a higher sensitivity to tolerances by a factor of 2–3 compared to steel–aluminum joints. A unified effective rivet length concept was developed to consolidate the geometric effects of all tolerances into a single physically meaningful parameter, enabling load-bearing capacity prediction with R2 > 0.95 across all evaluated loading directions. The sub-component validation employing T-joint specimens indicates a 2–3 fold amplification of tolerance effects at critical structural regions, providing experimental evidence for the hierarchical scaling principle. The methodology was implemented in a tolerance-dependent CONSTRAINED_SPR3 formulation, providing >99 % computational efficiency improvement while maintaining a deviation in maximum force prediction within ±7 %.

In many studies on network dynamics, the analysis is restricted to networks with one-dimensional internal dynamics. Here, we show how symmetry explains the relation between dynamical behavior of systems with one-dimensional internal dynamics and with higher dimensional internal dynamics, when the underlying network topology is the same. Fundamental networks of homogeneous coupled cell systems (B. Rink, J. Sanders. Coupled Cell Networks and Their Hidden Symmetries. SIAM J. Math. Anal. 46.2 (2014)) can be expressed in terms of monoid representations, which uniquely decompose into indecomposable subrepresentations. In the high-dimensional internal dynamics case, these subrepresentations are isomorphic to multiple copies of those one computes in the one-dimensional internal dynamics case. This has interesting implications for possible center subspaces in bifurcation analysis. We describe the effect on steady state and Hopf bifurcations in l-parameter families of network vector fields. The main results in that regard are that (1) generic one-parameter steady state bifurcations are qualitatively independent of the dimension of the internal dynamics and that, (2) in order to observe all generic l-parameter bifurcations that may occur for internal dynamics of any dimension, the internal dynamics has to be at least l-dimensional for steady state bifurcations and 2l-dimensional for Hopf bifurcations. Furthermore, we illustrate how additional structure in the network can be exploited to obtain even greater understanding of bifurcation scenarios in the high-dimensional case beyond qualitative statements about the collective dynamics. One-parameter steady state bifurcations in feedforward networks exhibit an unusual amplification in the asymptotic growth rates of individual cells, when these are one-dimensional (S. von der Gracht, E. Nijholt, B. Rink. Amplified steady state bifurcations in feedforward networks. Nonlinearity 35.4 (2022)). As another main result, we prove that (3) the same cells exhibit this amplifying effect with the same growth rates when the internal dynamics is high-dimensional.}}, author = {{von der Gracht, Sören and Nijholt, Eddie and Rink, Bob}}, issn = {{0960-0779}}, journal = {{Chaos, Solitons & Fractals}}, keywords = {{Coupled cell systems, Network dynamics, Dimension reduction, Bifurcation theory, Symmetry, Monoid representation theory}}, publisher = {{Elsevier BV}}, title = {{{Homogeneous coupled cell systems with high-dimensional internal dynamics}}}, doi = {{10.1016/j.chaos.2026.118196}}, volume = {{208}}, year = {{2026}}, } @inbook{60018, author = {{Grauthoff, Fabian and Kreter, Maximilian}}, booktitle = {{Speak Up!
