Web9 apr. 2024 · We and several others have studied the use of AQDS in flow batteries 26–29 and our research has shown that AQDS is one of the most robust and efficient redox materials for repeatedly storing and delivering charge at the negative electrode. 30–32 In addition, the large-scale manufacturing cost of AQDS is projected to be as low as $3/kg. … WebRedox-active organic molecules such as anthraquinone-2,6-disulfonate (AQDS) and natural organic matter (NOM) can act as electron shuttles thus facilitating electron transfer from Fe(III)-reducing bacteria (FeRB) to terminal electron acceptors such as Fe(III) minerals. In this research, we examined the length scale over which this electron shuttling can occur. …

Web2 apr. 2024 · AQDS has a rather complicated photochemistry in aqueous solution, which also depends on the pH of solution. The 3 AQDS transient spectra at pH = 11.7 is given below:. For basic aqueous solution (pH > 11) in the absence of oxygen the pathways of the 3 AQDS decay can be represented using Scheme 2 []:. After excitation AQDS … WebAQDS in 1 M sulphuric acid on a glassy carbon disk working electrode shows current peaks corresponding to reduction and oxidation of the anthraquinone species9–11 (Fig. 3d, solid trace). The peak separation of 34 mV is close to the value of 59 mV/n, where n is the number of electrons involved, expected for a two-electron process. flank steak in a crock pot recipe
