In-situ measurements of the optical absorption of dioxythiophene-based conjugated polymers

open access: yes, 2011
Conjugated polymers can be reversibly doped by electrochemical means. This doping introduces new sub-bandgap optical absorption bands in the polymer while decreasing the bandgap absorption. To study this behavior, we have prepared an electrochemical cell

Optically detected X-ray absorption spectroscopy measurements as a means to monitor corrosion layers on copper [PDF]

open access: yes, 2008
XANES and EXAFS information is conventionally measured in transmission through the energy-dependent absorption of X-rays or by observing X-ray fluorescence, but secondary fluorescence processes, such as the emission of electrons and optical photons (e.g.,

Membrane and Electrochemical Processes for Water Desalination: A Short Perspective and the Role of Nanotechnology

open access: yesMembranes, 2020
In the past few decades, membrane-based processes have become mainstream in water desalination because of their relatively high water flux, salt rejection, and reasonable operating cost over thermal-based desalination processes. The energy consumption of
