A polymorphic reconfigurable multi‐electrode device based on electrically bistable nanostructured metallic films. The adaptive reconfiguration properties of the nanostructured network under specific input voltages drive the reprogrammability of the device. This system can be employed for the implementation of polymorphic devices, which can be used both

Stretchable Energy Storage with Eutectic Gallium Indium Alloy
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

Exact solutions for pairing interactions [PDF]
The exact solution of the BCS pairing Hamiltonian was found by Richardson in 1963. While little attention was paid to this exactly solvable model in the remainder of the 20th century, there was a burst of work at the beginning of this century focusing on

Economic Viability of Photovoltaic Systems Providing Frequency Containment Reserve
This article investigates the feasibility of photovoltaic (PV) systems providing frequency containment reserve (FCR) in the Netherlands. The economic analysis demonstrates that a PV plant can profitably participate in FCR without battery storage by maintaining an active power reserve.

Finnish 20th Century History in Oral Narratives
The heritage about family’s past history progresses similarly to that of the established history. Both are created in a certain context and from a certain standpoint. Family heritage is formed through narrative history on the personal level, mediated by people’s and their contemporaries’ recollections.

Structural problems without structural solutions? Youth leaders' perceptions of their community
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with
