Then, we approximate both problems using temporal discretization. Additionally, we introduce a secant form considering the nonlinearity of elasto-plastic constitutive equations, which is approximated by a tangent form. Finally, we obtain numerical primal and dual solutions and their corresponding error approximations of discretized primal and dual problems, allowing to build several goal-oriented a posteriori error estimators on temporal and spatial adaptive refinement by inserting primal solutions, dual solutions and their error approximations as arguments in residuals of both weak forms as well as in the secant form of the bilinear residual.\r\n \r\n \r\n Findings\r\n An elasto-plastic material is investigated in a framework of goal-oriented error estimator by using separately several methods of error representation to deal with either temporal or spatial adaptive refinement, as well as with both refinements leading to an effective reduction of computational effort. Specifically, new error representations based on goal-oriented error estimators are presented and obtained from primal and dual residuals, which use only primal solutions or only dual solutions or a combination of primal and dual solutions as arguments. Error representations obtained from primal residuals and evaluated using only primal arguments do not require the formulation of a dual problem.\r\n \r\n \r\n Research limitations/implications\r\n The effectiveness of the different proposed methods is illustrated by an example of a perforated sheet for adaptive spatial refinement where new mesh adaptation methods of error representation are compared against existing mesh adaptation methods such as uniform mesh refinement, mesh refinement based on gradient indicators and adjoint-based methods in literature. The framework generates a balanced mesh consisting of fine, medium and coarse elements for accurate results, avoiding a numerically costly simulation with only fine elements.\r\n \r\n \r\n Originality/value\r\n All new proposed methods of error representation successfully estimate actual errors during mesh adaptivity. Furthermore, the proposed methods of error representation allow us to obtain significant reduction and equidistribution of spatial error at the end of the mesh adaptivity process. Their application to a framework of goal-oriented error estimation due to time and mesh adaptivity remains an open issue.\r\n ","lang":"eng"}],"user_id":"85414","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"_id":"63676","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0264-4401","1758-7077"]},"quality_controlled":"1","citation":{"bibtex":"@article{Tchomgue Simeu_Caylak_Ostwald_2026, title={Error representations for goal-oriented a posteriori error estimation in elasto-plasticity with applications to mesh adaptivity}, DOI={10.1108/ec-12-2023-0975}, journal={Engineering Computations}, publisher={Emerald}, author={Tchomgue Simeu, Arnold and Caylak, Ismail and Ostwald, Richard}, year={2026}, pages={1–40} }","short":"A.

In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference.","lang":"eng"}],"publication":"Photonics","language":[{"iso":"eng"}],"keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"year":"2026","issue":"2","quality_controlled":"1","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","date_created":"2026-02-02T07:18:03Z","publisher":"MDPI AG","status":"public","type":"journal_article","article_type":"original","article_number":"128","user_id":"158","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"61"}],"_id":"63827","citation":{"mla":"Metzner, Dominik, et al. “Approximating Incoherent Monochromatic Light Sources in FDTD Simulations.” Photonics, vol. 13, no. 2, 128, MDPI AG, 2026, doi:10.3390/photonics13020128.","bibtex":"@article{Metzner_Potthoff_Zentgraf_Förstner_2026, title={Approximating Incoherent Monochromatic Light Sources in FDTD Simulations}, volume={13}, DOI={10.3390/photonics13020128}, number={2128}, journal={Photonics}, publisher={MDPI AG}, author={Metzner, Dominik and Potthoff, Jens and Zentgraf, Thomas and Förstner, Jens}, year={2026} }","short":"D.

Its growing computational demands make energy efficiency a critical concern. Recent studies demonstrate FPGAs’ superior performance and energy efficiency for computing primitive ERIs, but the computation of highly contracted ERIs introduces significant algorithmic complexity and new design challenges for FPGA acceleration.In this work, we present SORCERI, the first streaming overlay acceleration for highly contracted ERI computations on FPGAs. SORCERI introduces a novel streaming Rys computing unit to calculate roots and weights of Rys polynomials on-chip, and a streaming contraction unit for the contraction of primitive ERIs. This shifts the design bottleneck from limited CPU-FPGA communication bandwidth to available FPGA computation resources. To address practical deployment challenges for a large number of quartet classes, we design three streaming overlays, together with an efficient memory transpose optimization, to cover the 21 most commonly used quartet classes in realistic atomistic simulations. To address the new computation constraints, we use flexible calculation stages with a free-running streaming architecture to achieve high DSP utilization and good timing closure.Experiments demonstrate that SORCERI achieves an average 5.96x, 1.99x, and 1.16x better performance per watt than libint on a 64-core AMD EPYC 7713 CPU, libintx on an Nvidia A40 GPU, and SERI, the prior best-performing FPGA design for primitive ERIs. Furthermore, SORCERI reaches a peak throughput of 44.11 GERIS (109 ERIs per second) that is 1.52x, 1.13x, and 1.93x greater than libint, libintx and SERI, respectively.

The material responses of both the fiber and matrix are modeled using strain energy functions that account for damage evolution, while a complete linearization of the homogenization process is derived to ensure the consistent implementation of the Newton–Raphson iteration scheme in large deformation simulations. The innovative aspect of this work lies in the constitutive linearization for the hyperelastic-plastic-damage formulation within a mean-field homogenization framework, providing an efficient Newton algorithm for modeling the nonlinear behavior of CFRP. A failure criterion for the hyperelastic model of fibers is introduced, along with a damage saturation variable in rate form for the matrix, effectively capturing damage evolution.

To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car\r\nbodies that combine different materials that require joining. Given the variety of materials, mechanical joining\r\nprocesses are preferred. Especially the current development of the Giga/Mega-casting process concerning\r\naluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car\r\nproduction, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often\r\nused in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a\r\nsolidification-joining correlation for the SPR process across a range of Si contents and solidification rates. The\r\npurpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby\r\nimproving versatility."}],"publication":"Journal of Manufacturing Processes"},{"date_updated":"2026-03-04T11:32:09Z","publisher":"Elsevier BV","author":[{"first_name":"Maik","full_name":"Gude, Maik","last_name":"Gude"},{"last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056","first_name":"Gerson"},{"last_name":"Flügge","full_name":"Flügge, Wilko","first_name":"Wilko"},{"first_name":"Linda","full_name":"Fröck, Linda","last_name":"Fröck"},{"first_name":"Christopher","last_name":"Wald","full_name":"Wald, Christopher"},{"last_name":"Neßlinger","full_name":"Neßlinger, Vanessa","first_name":"Vanessa"},{"last_name":"Dobrindt-Tittmann","full_name":"Dobrindt-Tittmann, Karsten","first_name":"Karsten"},{"first_name":"Juliane","last_name":"Troschitz","full_name":"Troschitz, Juliane"},{"first_name":"Fynn","last_name":"Neubert","full_name":"Neubert, Fynn"},{"last_name":"Hofmann","full_name":"Hofmann, Martin","first_name":"Martin"},{"orcid":"0000-0003-2147-8444","last_name":"Ostwald","full_name":"Ostwald, Richard","id":"106876","first_name":"Richard"},{"full_name":"Mathiszik, Christian","last_name":"Mathiszik","first_name":"Christian"},{"full_name":"Schmale, Hans Christian","last_name":"Schmale","first_name":"Hans Christian"},{"last_name":"Wallmersperger","full_name":"Wallmersperger, Thomas","first_name":"Thomas"},{"id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido"}],"date_created":"2026-01-20T09:06:03Z","volume":147,"title":"Corrosion of adhesively bonded alloys in maritime environments: A review","doi":"10.1016/j.ijadhadh.2026.104264","publication_status":"published","publication_identifier":{"issn":["0143-7496"]},"quality_controlled":"1","year":"2026","citation":{"apa":"Gude, M., Meschut, G., Flügge, W., Fröck, L., Wald, C., Neßlinger, V., Dobrindt-Tittmann, K., Troschitz, J., Neubert, F., Hofmann, M., Ostwald, R., Mathiszik, C., Schmale, H.

So far, investigations involving intimate covalent or ionic bonds have not been a focus. Yet, we show here that an established technique, involving thermocompressional wafer bonding, works well for creating twisted non-van der Waals interfaces. We have successfully bonded z-cut lithium niobate single crystals to create ferroelectric oxide interfaces with strong polar discontinuities and have mapped the associated emergent interfacial conductivity. In some instances, a dramatic change in microstructure occurs, involving local dipolar switching. A twist-induced collapse in the capability of the system to effec8tively screen interfacial bound charge is implied. Importantly, this only occurs around specific moiré twist angles with sparse coincident lattices and associated short-range aperiodicity.

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."}],"oa":"1","date_updated":"2026-03-10T08:27:15Z","volume":11,"author":[{"first_name":"Naresh","full_name":"Killi, Naresh","last_name":"Killi"},{"last_name":"Kumar","full_name":"Kumar, Amit","first_name":"Amit"},{"last_name":"Nebhani","full_name":"Nebhani, Leena","first_name":"Leena"},{"first_name":"Franziska","full_name":"Obst, Franziska","last_name":"Obst"},{"full_name":"Richter, Andreas","last_name":"Richter","first_name":"Andreas"},{"first_name":"Bernhard","full_name":"Reineke Matsudo, Bernhard","last_name":"Reineke Matsudo"},{"first_name":"Thomas","id":"30525","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101"},{"last_name":"Kuckling","id":"287","full_name":"Kuckling, Dirk","first_name":"Dirk"}],"doi":"10.1021/acsomega.5c09476","main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/abs/10.1021/acsomega.5c09476"}],"publication_identifier":{"issn":["2470-1343","2470-1343"]},"publication_status":"published","intvolume":" 11","citation":{"apa":"Killi, N., Kumar, A., Nebhani, L., Obst, F., Richter, A., Reineke Matsudo, B., Zentgraf, T., & Kuckling, D.

Extensive research has been conducted to enhance the multiplexing capacity for diverse wavefronts. However, the independence of multiplexed channels is fundamentally restricted in techniques using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing concept is presented based on non‐injective transformation. By employing joint optimization on two metasurfaces, different channels can be independently designed without any constraints on the output wavefronts. To validate this approach, ultra‐compact orbital angular momentum (OAM) sorters are designed. In these experiments, the output beams from different channels can be independently mapped to 2D positions with high fineness. In another application of wavefront‐multiplexed holography, 10‐channel multiplexing is experimentally achieved with minimal crosstalk and without the need for post‐processing. These results demonstrate the independence between channels enabled by the non‐injective transformation in the method. The precise wavefront control and high multiplexing capacity underscore its potential for scalable wavefront manipulation devices.","lang":"eng"}],"publication":"Advanced Materials"},{"publisher":"Waxmann","date_updated":"2025-12-04T18:40:07Z","author":[{"first_name":"Christoph","last_name":"Fröhleke","full_name":"Fröhleke, Christoph"},{"first_name":"Sebastian","full_name":"Habig, Sebastian","last_name":"Habig"},{"id":"54823","full_name":"Fechner, Sabine","last_name":"Fechner","orcid":"0000-0001-5645-5870","first_name":"Sabine"}],"date_created":"2025-12-04T18:39:55Z","title":"Erfassung handlungsorientierter Kompetenzen im Chemiepraktikum - Inwiefern kann die Performanz von Lehramtsstudierenden bei Prozessentscheidungen diagnostiziert werden?","publication_status":"inpress","quality_controlled":"1","edition":"2","place":"Münster","year":"2026","citation":{"apa":"Fröhleke, C., Habig, S., & Fechner, S.

Furthermore, introducing molecular intercalants enabled controlled crystallization into well-defined nanowires that function as Fabry–Pérot cavities. Cavities made from n = 2 to 4 perovskites support efficient and robust near-infrared, room-temperature optically pumped lasing with the threshold as low as 75.8 μJ/cm2, cavity quality factor over 3000, and negligible degradation over 106 pulses. A cleaved coupled nanolaser was fabricated as a proof-of-concept device for photonic applications."}],"file":[{"content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2026-01-08T20:51:12Z","creator":"fossie","date_created":"2026-01-08T20:51:12Z","file_size":5453427,"file_name":"2026-01 Jeong-Hui-Kim - JACS - Hydrogen-Bonded Organic Framework Enables Phase-Pure Layered Tin Perovskite Nanowires for Room-Temperature Lasing (with Purdue).pdf","file_id":"63533","access_level":"closed"}],"ddc":["530"],"keyword":["tet_topic_opticalantenna"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0002-7863","1520-5126"]},"has_accepted_license":"1","citation":{"ieee":"J.
