The Roles of Civil Society Associations in Organising the Informal Circular Economy

open access: yesSustainable Development, EarlyView.
ABSTRACT A circular economy (CE) transition requires more than technological innovation and market‐based solutions. It demands a circular society that values informal repair, reuse and sharing practices. This study investigates how civil society associations (CSAs) support such practices in an industrialised setting.

Curvature‐Controlled Polarization in Adaptive Ferroelectric Membranes

open access: yesSmall, EarlyView.
This study investigates PbTiO3‐based membranes that form self‐organized adaptive ripple patterns upon release from the substrate. The domain structure of the membrane is analyzed at different length scales, showing in‐plane domains at ripple crests and in‐plane/out‐of‐plane domains in flat regions.

Needle in a Haystack: Information Recovery in Low Signal‐to‐Noise Piezoresponse Force Microscopy Data

open access: yesSmall Methods, EarlyView.
Reconstruction of low signal‐to‐noise ratio signals enables improved information recovery in piezoresponse force microscopy data, even in data with a substantial amount of noise. Incorporating signal processing errors to detect and Bayesian matrix completion methods to reconstruct low SNR signals substantially alters the apparent PFM switching ...

Redefining Graphene Oxide: The Role of Organosulfate Groups in Charging Dynamics and Colloidal Stability

open access: yesSmall Structures, EarlyView.
This work redefines graphene oxide (GO) as a 2D polyelectrolyte by revealing the dominant role of organosulfate groups in its charging dynamics and stability. Challenging conventional models, the findings offer a predictive framework for the design and optimization of GO‐based membranes, electrodes, and nanomaterials across diverse technologies ...

Nanoimprinted Collagen Plasmonic Sensors

open access: yesSmall Structures, EarlyView.
A process to create collagen 3D nanostructures has been developed based on thermal nanoimprinting using mild conditions. This versatile process is suitable for transferring collagen patterns to both soft and rigid substrates, allowing for applications in various fields, including biomedicine and bio‐organic electronics.
