Okay, so, we did a thing. Writing a post a few weeks later as the manuscript is up in its properly styled electronic form. Here is a new #article on #electrochemical #copolymerization of #hydroquinone and #PEDOT, which is essentially its title. Apart from checking whether it's actually a #copolymer (rather than a composite), we adjusted synthesis parameters, studied charge transfer a bit, and threw in a little something regarding probable use as an #energy storing #ElectrodeMaterial.
There are also bits and pieces of other methods relevant to our ongoing projects, but the most curious thing for me personally (and the one that led me to near-exhaustion a few times when I thought that a fluke is an “aha!” moment) is the possibility of mixing two relatively simple compounds, bashing them with pulsed potential repeatedly and getting an outcome of a nice capacitive/conducting PEDOT response, on top of which we can have however much we want (well, up to about two-thirds) redox response of hydroquinone.
Anyway, we’ve been cooking for 2 years, because each time something happened, it did the result more interesting, until we were finally—well, not satisfied exactly—but sure that it would be compelling as a published article.

Potentials should not be described as anodic or cathodic.

Anodic/cathodic refer to currents only. Other quantities need not apply.

Nomenclature matters!

#Electrochemical #X-ray scattering unlocks secrets of ##redox enzymes

Colleagues have published a new article on #cobaltocenium-containing polymers (well, #polysiloxanes). Our lab has contributed to some #electrochemical characterization. This is also where I realized that, despite the deceptive similarity between ferrocenes and cobaltocenes, the latter are quite capricious, as they prefer #redox reactions in cathodic potential regions. The more challenges, the more interesting the task, I suppose. Anyway, here’s the link: https://doi.org/10.1021/acsapm.4c02238 [ACS / non-OA]

this guy wrote up a very cool introduction to cyclic voltammetry. Highly recommended!

"In this study, we introduce a straightforward and effective approach to produce P-doped hard carbon using #coffee grounds as the precursor, with H3PO4 serving as the doping agent. By varying the concentrations of H3PO4..we aimed to determine the optimal doping level..Our investigation revealed that using 2 M of H3PO4 as the dopant material for hard carbon led to promising #electrochemical performance when employed as an anode material for sodium-ion #batteries."
