2024年12月18日 · The phase, composition and structure of the prepared materials were characterized by transmission electron microscope (TEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and powder X-ray diffraction (XRD). The AQS, RGO and AQS/RGO on functionalized carbon cloth (FCC) electrodes were established.

2018年6月1日 · In this study, 1,5-naphathalene disulfonic acid (1,5-NDA) doped PEDOT/MXene composites were prepared by in situ chemical oxidation method. Two redox-active dopants, phosphomolybdic acid (H 3 PMo 12 O 40) and anthraquinone-2-sulfonate (AQS), are introduced to further increase the supercapacitive performances.

2021年5月5日 · Here, we introduce a simple, fast and efficient strategy to compound sodium anthraquinone-2-sulfonate (AQS) with reduction graphene oxide (rGO), obtaining the AQS/rGO hydrogels.

2020年2月21日 · We synthesize 15 salts and measure with UV–vis spectroscopy their solubilities, falling a wide range of 1 mM to 1.2 M. We further perform single-crystal X-ray diffraction (XRD) to understand the impact from the solid structure of the salts. The results reveal insights into the design of highly soluble molecules for aqueous RFBs.

The amorphous structure was con rmed using X-ray diffraction (XRD) patterns, in which the strong characteristic peaks of highly crystalline AQS disappeared for the AQS/G composites (Fig. 3d).

Reduced graphene oxide (RGO) loaded with sodium anthraquinone-2-sulfonate (AQS) was prepared using one-pot hydrothermal synthesis. The phase, composition and structure of the prepared materials were characterized by transmission electron microscope (TEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and ...

结果表明，rf和aqs显着加速了细胞向u( vi )的电子转移，从而增强了还原性u( vi )。 SEM、FTIR、XPS和XRD进一步证实了沉淀物的形成，表明钙镍矿[H 2 (UO 2 ) 2 (PO 4 ) 2 · 8H 2 O]成为腐烂链球菌细胞表面的主要产物。

2018年10月1日 · 本文首次将蒽醌-2-磺酸钠 (AQS)作为有机氧化还原活性材料进行研究，并加入高导电性的石墨烯纳米片以提高电子导电性，其中AQS的-SO3–官能团具有优异的亲水性，促进了AQS与还原氧化石墨烯 (rGO)在分子水平上复合，并形成了互相连接的三维干凝胶 (AQS@rGO)。 该复合材料在1 A/g电流密度下具有567.1 F/g的高比电容，在10 A/g循环10000圈能够保持89.1%的比容量。 第一性原理计算表明AQS与rGO的相互作用形成空间电荷层，极大促进了二者之间 …

2013年8月1日 · The results indicate that biotransformation of lepidocrocite cannot be measured in the absence of ETMs and phosphate in this study. In the presence of exogenous ETMs (AQC and AQS), XRD analysis of the solids remaining after lepidocrocite bioreduction showed a decrease of lepidocrocite peaks and an increase of green rust peaks (Fig. 2 (a)).
