HOT PCCP article

The article A review of stimuli-responsive polymer-based gating membranes was selected as a 2024 HOT arcticle in PCCP

Back Cover

Back Cover: In article Unusual Shell Morphologies of Responsive Amino Core-Shell Microgels Induced by pH During Shell Synthesis highlight the impact of the reaction pH during the formation of responsive amino core-shell microgels. While very fuzzy shells with particulate structures are formed at acidic or intermediate pH, denser core-shell microgels together with a secondary species are formed at alkaline conditions. The results point out the possibilities and importance of pH-control during synthesis of pH-responsive microgels.

Since 2014, the European Spallation Source ESS in Lund is under construction. Using a linear accelerator, neutrons will be generated which allow for example the investigation of soft matter structures and the study many new physical processes. In order to analyze the samples with the highest possible efficiency, researchers are developing special sample environments.

In an interview with Welt der Physik, Thomas Hellweg from Bielefeld University explains these special environments and how samples can be studied with neutrons in general.

New Research field "Smart Microgel based Membranes"

Within the framework of this new research line we have published recently two works.

These works show the high potential of microgel based membranes for different applications e.g. in electrochemical cells or catalytically active systems.

April 2021

BMBF instrumentation project: “FlexiProb” sample environment for the ESS:

Aim of the project is the development and implementation of dedicated soft matter sample environments for small angel neutron scattering instruments at the ESS. The project is in collaboration with the von Klitzing group at TU Darmstadt and the Müller-Buschbaum group at TU Munich.

In this context, 3 publications were issued in Appl. Sci. 2021, 11(9),:

Part I: The In Situ SANS/DLS Setup: https://www.mdpi.com/2076-3417/11/9/4089

Part II: The GISANS setup:https://www.mdpi.com/2076-3417/11/9/4036
