Electrochemical properties of quinones, antraquinones and their derivatives – potential redox-systems for flow batteries [PDF]
Practical interest in redox flow batteries has arisen in recent decades as a result of intensive development in the field of alternative energy (such as solar and wind) and the control of peak loads in industrial electrical networks.

Why 1,2‑quinone derivatives are more stable than their 2,3‑analogues? [PDF]
In this work, we have studied the relative stability of 1,2- and 2,3-quinones. While 1,2-quinones have a closed-shell singlet ground state, the ground state for the studied 2,3-isomers is open-shell singlet, except for 2,3-naphthaquinone that has a ...

Efficient photochemical activity and strong dichroism of single crystals of reaction centers from Rhodopseudomonas viridis [PDF]
Crystallized reaction centers from Rhodopseudomonas viridis (i) are photochemically active with electron transfer from the special pair to the quinones, (ii) show dichroism giving valuable information on the orientation of the different chromophores and (
