Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Indicators for energy security

Energy Policy, 2009
The concept of energy security is widely used, yet there is no consensus on its precise interpretation. In this research, we have provided an overview of available indicators for long-term security of supply (SOS). We distinguished four dimensions of energy security that relate to the availability, accessibility, affordability and acceptability of ...

Energy and Security

2010
A substantial amount of scholarly literature about the relationship between energy and security, and how it has changed over time, has been produced before the early 1970s through the 2000s. Relatively few scholarly works were written on energy and security prior to the 1970s, and few scholars paid attention to the growing dependence of the United ...
