Submissions are invited for a Topical Issue of EPJ E “Festschrift in honor of Philip (Fyl) Pincus”
Philip (Fyl) A. Pincus is among the leading theoreticians worldwide working on soft condensed matter, polymers, and complex fluids. His seminal work on the elongational energy of self-avoiding chains forms the basis for the study of polymers in confined geometries. Pincus introduced the idea that polymers under force break up into independent “blobs” (referred to as Pincus blobs in de Gennes' book on polymers) whose size is determined by the magnitude of the external force. In addition, Pincus is among the pioneers in having developed concepts necessary to understand the practical problem of colloid stabilization by adsorbed or grafted polymers. Furthermore, his scaling approach to elucidating the physical properties of polyelectrolytes is world-renowned even though the statistical mechanics of polyelectrolytes remains incomplete. His contributions have received both theoretical and experimental attention. Pincus was among the first scientists to recognize the importance of interfacial problems in soft condensed matter systems from a fundamental physics viewpoint as well as from the practical technological side. He has had a critical influence by having inspired and provided the scientific leadership for the first synchrotron study that was carried out on measuring the concentration profile for polymers near interfaces. In addition to his major contributions to polymer physics, for which he was awarded the American Physical Society's High Polymer Prize in 1992, Pincus has also been a leading scientist in elucidating (together with his students and collaborators) the unique role of electrostatic interactions in membrane systems. He and his collaborators were among a handful of independent “theoretical soft matter groups” worldwide that played a central role in understanding how charge fluctuation effects can lead to attractive interactions between similarly charged membranes. Aside from his numerous seminal contributions to the nascent soft- and bio-matter field, Pincus conducted highly visible research during the early stages of his career in more traditional solid-state physics, magnetism, superconductivity, one-dimensional conductors, and spin-Peierls transitions.
This Topical Issue will cover a broad range of topics of interest to the readership of EPJ E including advances in the understanding of physical and chemical aspects of Soft Matter and Biological Systems. (See: https://www.springer.com/journal/10189)

Submissions are invited for a Topical Issue of EPJ E on “Novel Molecular Materials and Devices from Functional Soft Matter”.
This Topical issue will focus on soft matter materials and devices.
Soft matter can be defined by a large response to weak external perturbations, with physical properties governed by local internal dynamics. It may contain ordered structures at mesoscopic scales, but appear disordered at molecular scales. Because of this, the ordered and disordered aspects of soft matter can be combined to manufacture innovative and original functional materials and devices. Since the range of soft matter materials is very broad, including polymers, gels, colloids, liquid crystals, and many biomaterials, there is a need for understanding their large response functions to combined stimuli.
The most ambitious course of action is then to develop multi-functional materials and devices that exploit two or more rheological, electrical, electronic, photo-physical, quantum chemical, or opto-electronic responses of soft matter. Solving grand challenges for new generations of functional materials demands, beyond understanding, the ability to control structure-function relationships over all length scales — from the individual molecular building blocks to the macroscopic device —. The aim of this Topical Issue is to provide an inspiring platform for the dissemination of the latest developments and discoveries in the design, simulation, modeling, synthesis, construction and characterization of soft matter structures for functional materials and devices.

Submissions are invited for a Topical Issue of EPJ E on “50 years of Small Angle Neutron Scattering at the ILL in Grenoble”.
Small-Angle Neutron Scattering (SANS) has become a workhorse technique to characterise systems from various scientific research areas such as soft condensed matter, biology, materials science, fundamental and applied physics to name but the most prominent fields. The Institut Laue — Langevin (ILL) has been one of the driving forces in establishing SANS as a technique of such importance and D11 remains the benchmark pin-hole SANS instrument. D11, the first SANS instrument at the ILL, was built in the early ‘70s and has been in user operation since September 1972. This special issue is the occasion to celebrate the 50th anniversary of small-angle neutron scattering at the ILL.

Submissions are invited for a Topical Issue of EPJ E on “Quantitative AI in Complex Fluids and Complex Flows: Challenges and Benchmarks".
The Collection deals with- open problems, challenges, and benchmarks for data-driven/equations-informed tools for data assimilation, predictability, (sub-grid-scale) modeling, inpainting, classification, and (optimal) control of Eulerian and Lagrangian problems in complex flows.
The aim is to move from proofs-of-concept to quantitative benchmarks and grand challenges also concerning scaling of the algorithms and complexity of the datasets.
Papers about interpretability, supremacy and usability when applied to realistic fluid dynamics problems in engineering, geophysics, biophysics and other fields would also be welcome.
