Enhancing the Electrical Conductivity and Long‐Term Stability of PEDOT:PSS Electrodes through Sequential Treatment with Nitric Acid and Cesium Chloride

open access: yesAdvanced Materials, Volume 36, Issue 41, October 10, 2024.
The conductivity of sub‐20‐nm thin poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) films is improved by treating them sequentially with HNO3 and CsCl. The resulting layers show enhanced crystallinity with electrical conductivity of up to 5500 S cm−1, with 85% of this value being retained after 270 d of storage in ambient air at ...

Technical and economic challenges for floating offshore wind deployment in Italy and in the Mediterranean Sea

open access: yesWIREs Energy and Environment, Volume 13, Issue 4, July/August 2024.
Offshore wind development complexity. Abstract Offshore wind is nowadays already well developed in the North European countries. Ninety‐nine percent of the offshore wind turbines are installed on fixed foundations in shallow waters. For areas with water depth greater than 50–60 m, the floating wind is the cheapest and mostly used technology.
