The above article, published online on 03 February 2020, in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Greg M. Swain; and Wiley-VCH GmbH. The authors submitted a report to the journal stating that the conclusions presented in the article could not be replicated with further experimentation and requesting a withdrawal of their article. Following the author‘s report, the publisher was informed by a third party of evidence of image manipulation in Figure 1A. In addition, a third party indicated that images in Figure 2 and Figure 3 had been reused and manipulated from a previous publication by different authors. The retraction has been agreed to because the evidence of image manipulation and duplication across different articles fundamentally compromises the journal‘s confidence in the data and conclusions presented in the article. The authors agree with retraction.

Among the energy demands, innovative solutions are required to power various devices. Enter paper‐based microfluidic fuel cells (PµFCs) running on eco‐friendly alcohols from biomass. While lightweight and disposable, they mainly rely on costly noble‐metal catalysts for high efficiency. In this context, the concept of photo paper batteries (pPBs), utilizing affordable sunlight‐activated semiconductors to drive alcohol oxidation on paper, opens the possibility to disposable and affordable energy solutions. Our review highlights recent progress in PµFCs fueled by alcohols like methanol, ethanol, ethylene glycol, and glycerol. We explore semiconductor advancements driving anodic reactions and envision the potential of pPBs.
在能源需求中,需要创新的解决方案为各种设备提供动力。纸基微流体燃料电池(PµFC)以生物质中的环保酒精为燃料。虽然这种燃料电池重量轻、可一次性使用,但主要依靠昂贵的贵金属催化剂来实现高效率。在这种情况下,相纸电池(pPBs)的概念利用经济实惠的阳光激活半导体来驱动纸张上的酒精氧化,为一次性和经济实惠的能源解决方案提供了可能性。我们的综述重点介绍了以甲醇、乙醇、乙二醇和甘油等酒精为燃料的 PµFCs 的最新进展。我们探讨了推动阳极反应的半导体进展,并展望了 pPBs 的潜力。

This work presents a fast and sensitive method, with an ex−situ bismuth film screen‐printed carbon electrode (ex−situ Bi−SPCE), for the determination of Cr(VI) through adsorptive stripping voltammetry (AdSV) using Pyrogallol Red (PGR) as complexing agent. The method is based on the oxidation of PGR by Cr(VI) and posterior complexation with Cr(III). To obtain a sensitive and selective method, the effects of various parameters such as pH, ligand concentration of PGR (C <sub>PGR</sub>), accumulation potential, and accumulation time (E <sub>acc</sub>, t <sub>acc</sub>) were optimized.

It is a significant issue to develop silicon/carbon composite anode with high‐capacity and long cycling stability for lithium‐ion batteries. However, the huge volume expansion of silicon during lithiation leads to severe pulverization of silicon, resulting in serious capacity fading over cycles. Herein, nano silicon integrated hard carbon (20Si@HC, 20 wt.% nano silicon) is prepared by pyrolyzing nano silicon in‐situ coated a conjugated microporous polymer (CMP). CMP‐derived hard carbon coating features developed porous structure, which not only deliver a high lithium storage capacity, but also provide enough space for the volume expansion of nano silicon.
