A series of unstable elastic structures exhibiting “exotic” behaviours is presented. These include the inverse Kapitza elastic pendulum [1], tensile buckling [2], Hopf bifurcation induced by a nonholonomic constraint [3], flutter induced by a piecewise-linear constraint [4], folding of an elastic rod [5], and buckling under a transverse uniform load [6]. These structures are then implemented in architected materials, and a rigorous homogenization technique is developed to determine the equivalent elastic continua, whose instability can in turn be analyzed. Using this technique, it is shown that the implementation of follower microforces leads to the realization of an elastic material that breaks the wall of hyperelasticity and is therefore non-Hermitian [7]. Finally, a nonlinear elastic material, derived through the homogenization of structural lattices, is shown to exhibit a rich variety of instability phenomena, including shear-band formation, disappearance, and reappearance, as well as mixed-mode and compaction localization. Remarkably, both classes of material can lose and subsequently recover ellipticity, leading to restabilization of the underlying lattice and even to the emergence of “islands” of stability [8].

We study the onset of 3D buckling of a slender elastic filament in a viscous shear flow at low Reynolds number and high Péclet number. Using the Euler–Bernoulli (elastica) description linearized about a straight configuration of arbitrary orientation, we show that the 3D stability problem can be reduced to a universal spectral problem governed by an orientation-dependent combination of the elastoviscous number and the shear geometry. Building on earlier in-plane eigenmodes, we solve the 3D eigenproblem and propose a simple analytic approximation of the unstable eigenfunctions as Gaussian wave packets. This yields the central scaling result: for highly flexible filaments, the characteristic wavenumber of the most unstable mode grows proportionally to the square root of this elastoviscous measure. The talk is based on our paper: P. Sznajder, P. Zdybel, L. Liu, and M. L. Ekiel-Jeżewska, Phys. Rev. E 110, 025104 (2024).

From March 24 to 26, 2026, Adolfo Poma, Dr. hab. from IPPT PAN, participated in the CECAM flagship workshop “𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐯𝐞 𝐚𝐧𝐝 𝐌𝐮𝐥𝐭𝐢𝐬𝐜𝐚𝐥𝐞 𝐌𝐨𝐝𝐞𝐥𝐥𝐢𝐧𝐠 𝐀𝐩𝐩𝐫𝐨𝐚𝐜𝐡𝐞𝐬 𝐭𝐨 𝐈𝐥𝐥𝐮𝐦𝐢𝐧𝐚𝐭𝐞 𝐂𝐫𝐲𝐨𝐄𝐌/𝐄𝐓 𝐃𝐚𝐭𝐚”, held at the Muséum de Toulouse (France). During the workshop, Dr. Poma presented his recent work: “𝐸𝑥𝑝𝑙𝑜𝑟𝑖𝑛𝑔 𝐶𝑜𝑛𝑓𝑜𝑟𝑚𝑎𝑡𝑖𝑜𝑛𝑎𝑙 𝐷𝑦𝑛𝑎𝑚𝑖𝑐𝑠 𝑜𝑓 𝑀𝑒𝑔𝑎𝑑𝑎𝑙𝑡𝑜𝑛-𝑆𝑐𝑎𝑙𝑒 𝑃𝑟𝑜𝑡𝑒𝑖𝑛𝑠 𝑤𝑖𝑡ℎ 𝑡ℎ𝑒 𝐺𝑜̄𝑀𝑎𝑟𝑡𝑖𝑛𝑖 3 𝐴𝑝𝑝𝑟𝑜𝑎𝑐ℎ.” In his talk, he introduced an advancement of the GōMartini 3 model, extending previous research to better capture conformational changes in large protein complexes. The approach integrates dynamic contacts derived from all-atom molecular dynamics (AA-MD), reducing the number of Gō interactions while preserving key structural information. This makes the method particularly well-suited for studying megadalton-scale protein assemblies commonly observed in cryoEM/ET data. Its potential has already been demonstrated in analyses of the long-term dynamics of SARS-CoV-2 spike protein variants, highlighting applications in biomedical research.

We’re excited to share the public demonstration of IPPT PAN’s innovative aerostat platform, developed in collaboration with Adaptronica Sp. z o.o. and XY Sensing Sp. z o.o., which tackles today’s airspace monitoring challenges. 🤝 The event brought together representatives from government, the military, and the scientific community, highlighting the project’s significance and real-world potential. 👉 The tethered aerostat lifts advanced observation equipment hundreds of meters above the ground, combining optical, thermal, acoustic, and passive radar systems to provide a complete picture of the airspace — all without emitting signals. While primarily designed for national security, the platform’s applications go far beyond: border and police support, critical infrastructure protection, airport and railway monitoring, and crowd surveillance at major events. Its scalable design also opens doors to environmental research, disaster response, and wildlife monitoring, showing its potential as a versatile societal tool. Developed over five years and funded by the National Centre for Research and Development (#NCBR) under joint programs with the National Science Centre (#NCN), the aerostat’s structural solutions are based on patents granted to IPPT PAN by the Polish Patent Office.
