The comparison with the experimental values of Δf and ΔΓ allows to estimate the stiffness of the contacts between the spheres and the resonator surface. The contact stiffness is of interest in contact mechanics, but also in sensing because it depends on the properties of thin films situated between the resonator surface and the sphere. The simulation differs from previous implementations of FreqD‐LBM insofar, as the material inside the particles is not included in the FreqD‐LBM algorithm. Rather, the particle surface is configured to be an oscillating boundary. The amplitude of the particles' motions (displacement and rotation) is governed by the force balance at the surface of the particle. Because the contact stiffness enters this balance, it can be derived from experimental values of Δf and ΔΓ. The simulation reproduces experiments by the Krakow group. For sufficiently small spheres, a contact stiffness can be derived from the comparison of the simulation with the experiment.","lang":"eng"}],"language":[{"iso":"eng"}],"issue":"11","quality_controlled":"1","year":"2023","date_created":"2025-12-18T17:03:12Z","publisher":"Wiley","title":"Stiffness of Contacts between Adsorbed Particles and the Surface of a QCM‐D Inferred from the Adsorption Kinetics and a Frequency‐Domain Lattice Boltzmann Simulation"},{"title":"Effect of Noise on Determining Ultrathin-Film Parameters from QCM-D Data with the Viscoelastic Model","doi":"10.3390/s23031348","date_updated":"2025-12-18T17:39:52Z","publisher":"MDPI AG","date_created":"2025-12-18T17:05:00Z","author":[{"last_name":"Johannsmann","full_name":"Johannsmann, Diethelm","first_name":"Diethelm"},{"full_name":"Langhoff, Arne","last_name":"Langhoff","first_name":"Arne"},{"first_name":"Christian","id":"117722","full_name":"Leppin, Christian","last_name":"Leppin"},{"last_name":"Reviakine","full_name":"Reviakine, Ilya","first_name":"Ilya"},{"first_name":"Anna M.

It can provide gravimetric as well as nongravimetric information about a film, such as its thickness and mechanical properties. The interpretation of sets of overtone-normalized frequency shifts, ∆f/n, and overtone-normalized shifts in half-bandwidth, ΔΓ/n, provided by QCM-D relies on a model that, in general, contains five independent parameters that are needed to describe film thickness and frequency-dependent viscoelastic properties. Here, we examine how noise inherent in experimental data affects the determination of these parameters. There are certain conditions where noise prevents the reliable determination of film thickness and the loss tangent. On the other hand, we show that there are conditions where it is possible to determine all five parameters. We relate these conditions to the mathematical properties of the model in terms of simple conceptual diagrams that can help users understand the model’s behavior. Finally, we present new open source software for QCM-D data analysis written in Python, PyQTM."}],"status":"public","type":"journal_article","publication":"Sensors"},{"publication":"Results in Physics","type":"journal_article","status":"public","_id":"63229","user_id":"117722","article_number":"106219","language":[{"iso":"eng"}],"extern":"1","publication_identifier":{"issn":["2211-3797"]},"publication_status":"published","year":"2023","intvolume":" 45","citation":{"ama":"Johannsmann D, Petri J, Leppin C, Langhoff A, Ibrahim H.

Based on the discovery of a gradient structure acting at regularity levels mild enough to be consistent with degeneracy-driven limitations of smoothness information, in this general setting it is shown that with some measurable limit profileu∞and some null setN⋆⊂(0,∞), a corresponding global generalized solution, known to exist according to recent literature, satisfiesρ(u(⋅,t))⇀⋆ρ(u∞)in L∞(Ω) and v(⋅,t)→0in Lp(Ω)for all p⩾1as(0,∞)∖N⋆∋t→∞, whereρ(ξ):=ξ2(ξ+1)2,ξ⩾0. In the particular case when eithern⩽2andα⩾1is arbitrary, orn⩾1andα∈[1,2], additional quantitative information on the deviation of trajectories from the initial data is derived. This is found to imply a lower estimate for the spatial oscillation of the respective first components throughout evolution, and moreover this is seen to entail that each of the uncountably many steady states(u⋆,0)of (⋆) is stable with respect to a suitably chosen norm topology.","lang":"eng"}],"user_id":"31496","_id":"63281","language":[{"iso":"eng"}],"issue":"8","publication_status":"published","publication_identifier":{"issn":["0951-7715","1361-6544"]},"citation":{"ama":"Winkler M.

Apart from that, these solutions are seen to stabilize toward some equilibrium, and as a qualitative effect genuinely due to degeneracy in diffusion, a criterion on initial smallness of the second component is identified as sufficient for this limit state to be spatially nonconstant.\r\n "}],"status":"public","publication":"Annales de l'Institut Henri Poincaré C, Analyse non linéaire","type":"journal_article","title":"A quantitative strong parabolic maximum principle and application to a taxis-type migration–consumption model involving signal-dependent degenerate diffusion","doi":"10.4171/aihpc/73","publisher":"European Mathematical Society - EMS - Publishing House GmbH","date_updated":"2025-12-18T20:14:52Z","volume":41,"author":[{"full_name":"Winkler, Michael","id":"31496","last_name":"Winkler","first_name":"Michael"}],"date_created":"2025-12-18T19:08:10Z","year":"2023","intvolume":" 41","page":"95-127","citation":{"mla":"Winkler, Michael. “A Quantitative Strong Parabolic Maximum Principle and Application to a Taxis-Type Migration–Consumption Model Involving Signal-Dependent Degenerate Diffusion.” Annales de l’Institut Henri Poincaré C, Analyse Non Linéaire, vol. 41, no. 1, European Mathematical Society - EMS - Publishing House GmbH, 2023, pp. 95–127, doi:10.4171/aihpc/73.","short":"M.
