In addition, a statistical evaluation is performed to determine the design-relevant strength characteristics with a survival probability Ps of 97.5 % for both materials in the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half of which are heat treated, geometrically measured and then subjected to a burst pressure test to experimentally determine the failure-critical internal pressure. These results are compared with calculated burst pressures.

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"}],"status":"public","_id":"63676","user_id":"85414","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"language":[{"iso":"eng"}],"publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["0264-4401","1758-7077"]},"year":"2026","citation":{"short":"A.

Here, we employ an operando approach, combining a fast electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy to investigate interfacial transformations of Co3O4 nanoparticle electrodes in alkaline electrolyte. We identify two distinct regimes during the anodic sweep prior to the macroscopic OER onset. At lower potentials, the catalyst interface remains mechanically rigid while reversibly associating several OH−/H2O species per oxidized cobalt site. At higher potentials, pronounced softening of the interface occurs alongside further uptake of electrolyte species. This indicates amorphization and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical conditioning treatment can suppress mass and compliance hysteresis without affecting OER activity, suggesting that most incorporated electrolyte species do not participate in the OER. EIS further reveals that OER intermediates form well below the apparent OER onset potential. These results advance our mechanistic understanding of interfacial transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive operando technique for probing electrocatalyst transformations.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["electrocatalysis","Co3O4","EQCM-D","OER"]},{"intvolume":" 289","citation":{"bibtex":"@article{Schumacher_Guevara-Carrion_Kasper_Paul_Elsner_Peters_Wollny_Bluemel_Hoelscher_Brzoska-Steinhaus_et al._2026, title={Aging of polyurethane foam: Experimental analysis and modeling of cell gas composition and thermal conductivity}, volume={289}, DOI={10.1016/j.applthermaleng.2026.129850}, number={129850}, journal={Applied Thermal Engineering}, publisher={Elsevier BV}, author={Schumacher, Daniel and Guevara-Carrion, Gabriela and Kasper, Tina and Paul, Andreas and Elsner, Andreas and Peters, Bettina and Wollny, Wenke and Bluemel, Marcus and Hoelscher, Heike and Brzoska-Steinhaus, Nicola and et al.}, year={2026} }","short":"D.

Aging is primarily driven by gas permeation, wherein the initially present cell gases carbon dioxide and cyclopentane are progressively replaced by nitrogen and oxygen from the ambient, resulting in an increased thermal conductivity and reduced insulation performance. The cell gas composition is measured over 1400 days employing gas chromatography, and the thermal conductivity of the foam is measured over 190 days. Morphological foam characteristics, such as average cell diameter, are determined via scanning electron microscopy and barrier measurements are performed to estimate the effective diffusion coefficient of oxygen. To simulate the aging process, one-dimensional and three-dimensional models are developed for both diffusive mass transfer as well as heat transfer. The present model for the thermal conductivity explicitly accounts for condensation effects, i.e. partial condensation of cyclopentane and carbon dioxide occurring at around 12°C, which significantly influences the insulation behavior of the foam. Sensitivity analyses indicate that an initial cell gas pressure of approximately 0.7 bar yields results that closely coincide with the experimental measurements, where the three-dimensional model demonstrates better accuracy. These measurements and simulations provide valuable insights for evaluating and predicting the long-term degradation of the insulation performance of PUR foams.","lang":"eng"}],"publication":"Applied Thermal Engineering","keyword":["Polyurethane","Foam","Gas permeation","Diffusion models","Thermal conductivity","Condensation","Gas chromatography","Scanning electron microscopy"],"language":[{"iso":"eng"}]},{"year":"2026","citation":{"short":"B.

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."}],"publisher":"MDPI AG","date_created":"2026-02-02T07:18:03Z","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","quality_controlled":"1","issue":"2","year":"2026","_id":"63827","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"61"}],"user_id":"158","article_number":"128","article_type":"original","type":"journal_article","status":"public","date_updated":"2026-02-02T21:38:34Z","oa":"1","volume":13,"author":[{"first_name":"Dominik","full_name":"Metzner, Dominik","last_name":"Metzner"},{"first_name":"Jens","full_name":"Potthoff, Jens","last_name":"Potthoff"},{"first_name":"Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","full_name":"Zentgraf, Thomas","id":"30525"},{"first_name":"Jens","full_name":"Förstner, Jens","id":"158","orcid":"0000-0001-7059-9862","last_name":"Förstner"}],"doi":"10.3390/photonics13020128","main_file_link":[{"url":"https://www.mdpi.com/2304-6732/13/2/128","open_access":"1"}],"publication_identifier":{"issn":["2304-6732"]},"publication_status":"published","intvolume":" 13","citation":{"ieee":"D.

Post-synthetic functionalization involves nitration of phenylene moieties, reduction to amines, and ring-opening of propane or butane sultones to graft sulfonic acid groups via flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization degrees.

This enhances dimensional accuracy in sparse-view computed tomography (CT). However, existing approaches offer no direct means to exploit this criterion for automatic scan-angle optimization. We propose a method that uses a virtual representation of the CT setup, including an STL surface model of the inspected part, to automatically identify taskspecific scan angles. Using elementary vector calculus, the algorithm determines projection directions that generate tangential X-rays for targeted surface segments. To support different levels of geometric complexity, we introduce two variants of the angle-selection procedure. The methods were experimentally validated on two objects with distinct absorption and geometric characteristics. For a steel gauge block, employing the minimum number of task-specific projections required for surface-data completeness substantially outperformed a conventional high-projection scan. For a geometrically more complex test object, surface-related errors were still reduced within the region of interest. The proposed approach – particularly suited for flat surface structures and not accounting for image-degrading factors other than cone-beam artifacts – shows promise for high-throughput dimensional metrology of mono-material parts.","lang":"eng"}]},{"date_updated":"2026-02-13T08:36:12Z","publisher":"Buske","author":[{"last_name":"Topalovic","orcid":"0009-0002-7576-3558","id":"23088","full_name":"Topalovic, Elvira","first_name":"Elvira"},{"first_name":"Laura","full_name":"Drepper, Laura","id":"40689","last_name":"Drepper","orcid":"https://orcid.org/0009-0007-6807-6684"},{"first_name":"Alisa","last_name":"Blachut","id":"37811","full_name":"Blachut, Alisa"}],"date_created":"2025-03-12T06:41:09Z","title":"Kausalität im Längsschnitt.
