Plasma, owing to its reactivity and nonequilibrium properties, is a unique field commonly used in material processing. In recent years, plasma processing with a liquid phase has attracted considerable attention owing to its important advantages, such as high electron density and the availability of a wide variety of reactions in solutions. However, plasma-in-liquid material synthesis is occasionally difficult to control and guidelines are lacking. In this study, we investigated whether the hard-soft acid–base (HSAB) principle, which is often applied in material synthesis, is applicable to the plasma-in-liquid process and demonstrated that organic solvent-derived substances produced by plasma-in-liquid processing reacted with solutes according to the HSAB principle. These results suggest that the HSAB principle may apply to plasma-in-liquid processing.

等离子体因其反应性和非平衡特性，是材料加工中常用的一个独特领域。近年来，液相等离子体加工因其电子密度高、可在溶液中进行多种反应等重要优势而备受关注。然而，液相等离子体材料合成有时难以控制，也缺乏指导原则。在本研究中，我们研究了经常应用于材料合成的硬软酸碱（HSAB）原理是否适用于等离子体液中工艺，并证明了等离子体液中工艺生产的有机溶剂衍生物质与溶质的反应符合 HSAB 原理。这些结果表明，HSAB 原理可能适用于等离子体液中处理。

Atmospheric-pressure plasma-enhanced film deposition with single-filament dielectric-barrier discharges (DBDs) in argon was investigated using allyltrimethylsilane (ATMS) as a precursor. Nonionic deposition in the discharge zone is largely precluded by a rapid cross-flow of the source gas, containing between 50 and 2000 ppm of ATMS. The performed experimental studies show a surprisingly large deposited film mass per transferred elementary charge between 220 and 540 amu. Film growth experiments, mass-spectrometric studies, and kinetic considerations led to the conclusion that the deposition process is a cationic surface polymerization, initiated by ions produced in the DBD by energy transfer from long-lived excited Ar species and propagated by addition of ATMS monomer molecules.

研究人员使用烯丙基三甲基硅烷（ATMS）作为前驱体，在氩气中使用单丝介质阻挡放电（DBD）进行了大气压等离子体增强薄膜沉积。放电区中的非离子沉积在很大程度上被源气的快速横流所阻止，源气中含有 50 到 2000 ppm 的 ATMS。所进行的实验研究表明，每转移一个基本电荷（220 至 540 amu），沉积的薄膜质量就会大得惊人。通过薄膜生长实验、质谱研究和动力学分析得出的结论是，沉积过程是一种阳离子表面聚合反应，由 DBD 中通过长寿命激发 Ar 物种的能量转移产生的离子引发，并通过添加 ATMS 单体分子而传播。

Enhancing discharge energy in dielectric barrier discharge (DBD) is vital for various applications. This study establishes a theoretical formula for predicting enhanced discharge in multi-needle-plate (MP) DBD, accounting for factors like needle count, rotation speed, and voltage frequency. Experiments validate the formula's accuracy, showing that precisely matched parameters result in enhanced discharge power, heightened streamer luminosity, and curved streamer channels. Lissajous figures in MP DBD exhibit elliptical shapes due to residual discharges during voltage fall. Statistical analysis of current pulses and discharge images confirms that dielectric plate rotation increases discharges and extends their duration during voltage fall. Numerical simulations highlight surface charge movement's role in enhancing the electric field and affecting streamer propagation direction in the air gap.

提高介质阻挡放电(DBD)中的放电能量对于各种应用都是至关重要的。考虑针数、转速和电压频率等因素，建立了预测多针板(MP) DBD中放电增强的理论公式。实验验证了公式的准确性，表明精确匹配的参数可以提高放电功率，提高流光亮度，并使流光通道弯曲。由于电压下降时的残余放电，MP DBD中的利萨图呈现椭圆形状。电流脉冲和放电图像的统计分析证实，介质板旋转增加了放电，并延长了电压下降时放电的持续时间。数值模拟突出了表面电荷运动对电场的增强作用和对流光在气隙中的传播方向的影响。

This special issue highlights renewable energies (REs). Among them, renewable electricity is becoming the most accessible and flexible low-carbon energy source. It can potentially allow achieving a drastic reduction of CO2 emissions that will contribute to our future sustainable society. RE is not limited to the development of high-performance energy devices, such as photovoltaics, fuel cells, and secondary batteries. Importantly, the utilization of RE in sustainable transformation and valorization of widely available yet hard-to-activate small carbon and hydrogen-containing molecules, such as CO2, CH4, and H2O, are vital for the production of low-carbon e-fuels and sustainable chemicals.The transition to a low-carbon footprint using RE is known as the Power-to-X concept. Photochemistry, electrochemistry, and a combination of these technologies have been heavily studied and explored.[1] Microwave and resistive heating is also studied as an alternative low-carbon high-temperature heat source used in chemical processes.[2, 3] Further, thermal plasma technology attracts keen attention for cracking methane to (turquoise) hydrogen and carbon black. Thermal plasma powered by RE minimizes carbon emission, equivalent to CH4 steam reforming combined with CCS.[4]More recently, plasma catalysis has become an emerging low-carbon footprint technology that can benefit from the efficient use of RE to control chemical reactions such as CH4 reforming, CO2 conversion, and N2 fixation.[5] Plasma-generated reactive species initiate chemical reactions at much lower temperatures than conventional thermal catalysis. In the meantime, plasma is generating simultaneously activated species (e.g., radicals) and heat, enabling operation of a catalytic reactor without an additional external heat source. This ability to perform endothermal reactions at relatively low temperatures is in contrast to an electrochemical reaction, such as a solid electrolyte, where the reaction temperature is limited in a narrow window due to the charge transport properties of electrolyte materials. Plasma catalysis is not limited by the combination of nonthermal plasma and heterogeneous catalysts but is closely related to standalone plasma technology for CO2 splitting and N2 fixation, which is also known as plasma conversion. Plasma catalysis has gained recognition as the key research topic in the Gordon Research Conference (Plasma Processing Science) over the decades. Highly cited review articles on plasma catalysis have also been accessible since late 2010.[6-10]This special issue focuses on plasma–catalyst coupling technology for gas

本期特刊重点介绍可再生能源(REs)。其中，可再生电力正成为最易获取、最灵活的低碳能源。它可以潜在地实现二氧化碳排放量的大幅减少，这将有助于我们未来的可持续社会。可再生能源并不局限于高性能能源设备的开发，如光伏、燃料电池和二次电池。重要的是，利用可再生能源对广泛可用但难以活化的小碳和含氢分子(如CO2、CH4和H2O)进行可持续转化和增值，对于生产低碳电子燃料和可持续化学品至关重要。使用可再生能源向低碳足迹的过渡被称为Power-to-X概念。光化学、电化学以及这些技术的结合已经得到了大量的研究和探索。[1]微波和电阻加热也被研究作为一种替代的低碳高温热源用于化工过程。[2,3]此外，热等离子体技术将甲烷裂解为(绿松石)氢和炭黑引起了人们的关注。由RE驱动的热等离子体最大限度地减少了碳排放，相当于CH4蒸汽重整结合CCS。[4]最近，等离子体催化已经成为一种新兴的低碳足迹技术，它可以受益于RE的有效利用来控制化学反应，如CH4重整、CO2转化和N2固定。[5]等离子体产生的反应物质在比传统热催化低得多的温度下启动化学反应。与此同时，等离子体同时产生活性物质(如自由基)和热量，使催化反应器无需额外的外部热源即可运行。这种在相对较低温度下进行吸热反应的能力与电化学反应相反，例如固体电解质，由于电解质材料的电荷传输特性，反应温度限制在一个狭窄的窗口内。等离子体催化并不局限于非热等离子体和多相催化剂的结合，而是与分离CO2和固定N2的独立等离子体技术密切相关，也称为等离子体转化。几十年来，等离子体催化已成为戈登研究会议(等离子体处理科学)的重点研究课题。自2010年底以来，关于等离子体催化的高引用评论文章也可以访问。[6-10]本期特刊聚焦于等离子体-催化剂耦合气体转化技术，由1篇综述、1篇展望和8篇原创研究论文组成。本文介绍了用于CH4和CO2转化的流化床DBD反应器的概念。[11]讨论了等离子体表面相互作用中自由基通量的增加和传热的增强。展望文章描述了从等离子体-催化剂反应场分离产物对提高能源效率的重要性。[12]除了适当的催化剂选择外，产物分离策略对于最大化等离子体诱导的协同效应也很重要。此外，还介绍了等离子体-催化剂耦合碳氢化合物重整技术，如DBD合成CH3OH[13]和热等离子体合成C2H5OH和CH4[14]。提出了利用等离子体-液体界面进行CO2转化[15]，这是验证Rouwenhorst和Lefferts提出的产物分离概念的理想反应体系[12]。通过纳秒脉冲等离子体的化学动力学模型[16]和热与DBD集成系统的过程模拟[17]，对CH4重整的等离子体催化进行了数值研究。从干式甲烷重整反应器流出物中分离CO2通常是能源密集型的，但由于需要较高的CO2:CH4比率，因此必须提高产品收率;本文从应用的角度提供了有见地的信息。此外，还介绍了辉光放电制备合金催化剂[18]、等离子体臭氧发生器净化工业规模废气[19]、热等离子体与催化剂结合固定N2[20]。最后，我们要感谢本期特刊的所有撰稿人、审稿人和《等离子体过程与聚合物》的编辑人员，感谢他们杰出而持续的支持。我们希望这期特刊能提高人们对等离子体催化作为一种新兴电气化技术的认识。此外，我们希望读者获得机械的见解，并找到刺激，有助于从实验室到工业规模的技术转移，这可能涉及多个分散的相对较小的单位。

Cancer-targeting carbon quantum dots (CQDs) with red-light absorption/emission featuring inherent biological functionality and deep biological penetration depth are promising for biomedical applications. However, traditional high-temperature and high-pressure synthesis processes result in unpredictable functionalities and uncontrollable optical properties due to the functional group loss. Here, plasma electrochemical treatment is introduced to overcome this issue. The synthesized CQDs in this work have excellent folate receptor cancer-targeting ability, red-light absorption/emission, and pronounced photodynamic therapy effect. The CQDs produced by the plasma electrochemical method preserve most of the functional groups from precursors, thus making them to fully inherit the bio-functionality and photophysical properties of precursors. This work opens new opportunities for plasma-based processes to controllably synthesize functionalized CQDs for diverse biomedical and environmental applications.

靶向癌症的碳量子点(CQDs)具有固有的生物功能和较深的生物穿透深度，在生物医学领域具有广阔的应用前景。然而，传统的高温高压合成工艺由于官能团的损失，导致功能不可预测，光学性质不可控。本文介绍了等离子体电化学处理技术来克服这一问题。本研究合成的CQDs具有优异的叶酸受体肿瘤靶向能力、红光吸收/发射能力和明显的光动力治疗效果。等离子体电化学方法制备的CQDs保留了前驱体的大部分官能团，从而充分继承了前驱体的生物功能和光物理性质。这项工作为基于等离子体的工艺控制合成功能化cqd提供了新的机会，可用于各种生物医学和环境应用。

The use of electricity for the industry's transition to a decarbonized economy requires optimization of the energy transfer to deliver efficient, cost-effective processes. Industrial demand for high-density plasmas over a wide pressure range has stimulated the use of microwave plasma (MWP) applications. In high-temperature processing, when microwaves of the correct frequency are absorbed by the plasma, the plasma particles absorb energy from the electromagnetic field and transfer it to the other particles through collisions, heating them. This rapid heating gives MWP properties that can be exploited to increase the conversion, selectivity, and/or energy efficiency of chemical processes. Here, we address questions raised by industrial users who wish to better understand the limitations of MWP applications.

为了实现行业向脱碳经济的过渡，电力的使用需要优化能源转移，以提供高效、经济的流程。工业对宽压力范围内高密度等离子体的需求刺激了微波等离子体(MWP)应用的使用。在高温加工中，当正确频率的微波被等离子体吸收时，等离子体粒子从电磁场中吸收能量，并通过碰撞将其传递给其他粒子，加热它们。这种快速加热赋予了MWP特性，可以用来提高化学过程的转化率、选择性和/或能源效率。在这里，我们解决了希望更好地理解MWP应用程序的局限性的工业用户提出的问题。

We would like to correct the confusing last sentence of Sec. 2.11 and replace three out of thirty images in Figure 3. The last sentence in this section gives a confusing impression regarding why deep anesthesia was needed if cells were extracted from dead mice. We aim to eliminate this ambiguity in the last sentence of Section 2.11. Unfortunately, an unexpected issue arose during the preparation phase, resulting in duplicate images within the composite figures due to image naming discrepancies. This error occurred in Figure 3a (PAM (60 s) AO/PI, PAM (60 s) + CAR (H&E)) and Figure 3c (PAM (60 s) AO/PI). We have now rectified this issue and presented the corrected figure in this corrigendum.

Details are in the caption following the image — **Figure 3**

(a) AO/PI staining and H&E staining of GC cells; (b) AO/PI staining and H&E staining of A2780 CP cells; (c) AO/PI staining and H&E staining of SKOV-3 cells. AO/PI, acridine orange/propidium iodide; CAR, carboplatin; CTRL, control; GC, granulosa cell; H&E, hematoxylin and eosin; PAM, plasma-activated medium.

Last sentence of Section 2.11: The mice underwent deep anesthesia before being killed, and all surgical procedures were conducted with utmost care to minimize any potential suffering. Subsequently, cell extraction was carried out following the detailed protocol outlined in Section A.3 of the Supplementary Information.

The updated figure is provided below:

It should be noted that the replaced photos are from the same batch of experiments as all other experiments in the rest of the figure, and all original photos and lab records were double-checked carefully. We would like to assure you that this correction does not impact the overall results or conclusions of our study. We apologize for any confusion or inconvenience caused by this error.

This feature article presents insights concerning the correlation of plasma-enhanced chemical vapor deposition and plasma-enhanced atomic layer deposition thin film structures with their barrier or membrane properties. While in principle similar precursor gases and processes can be applied, the adjustment of deposition parameters for different polymer substrates can lead to either an effective diffusion barrier or selective permeabilities. In both cases, the understanding of the film growth and the analysis of the pore size distribution and the pore surface chemistry is of utmost importance for the understanding of the related transport properties of small molecules. In this regard, the article presents both concepts of thin film engineering and analytical as well as theoretical approaches leading to a comprehensive description of the state of the art in this field. Perspectives of future relevant research in this area, exploiting the presented correlation of film structure and molecular transport properties, are presented.

本文介绍了等离子体增强化学气相沉积和等离子体增强原子层沉积薄膜结构与它们的屏障或膜性质的关系。虽然原则上可以应用类似的前驱体气体和工艺，但调整不同聚合物衬底的沉积参数可以导致有效的扩散屏障或选择性渗透。在这两种情况下，对膜生长的理解以及对孔径分布和孔表面化学的分析对于理解小分子的相关输运性质至关重要。在这方面，本文介绍了薄膜工程的概念和分析以及理论方法，从而全面描述了该领域的最新技术。展望了该领域未来相关研究的前景，并进一步探讨了膜结构与分子输运性质之间的关系。

We doped nitrogen into monolayer graphene using reactive nitrogen species from a dielectric barrier discharge (DBD). After 30 s of treatment, the graphene monolayer had a moderate degree of damage (I_D/I_G = 1.2) and an increase in the N-atom (pyrrolic) and O-atom (mixed) content. During long treatment times (20 min), the treated area increased radially and the graphene was destroyed. Overall, the N-atom content increased with increasing operating voltage of the DBD source. When the graphene was treated with only neutral reactive nitrogen species, the N-atom content and type remained unchanged. Therefore, we hypothesize that the primary reactive species resulting in pyrrolic N-doping from the DBD are neutrals such as N(⁴S) and possibly N(²P).

我们利用来自介质阻挡放电(DBD)的活性氮物质将氮掺杂到单层石墨烯中。处理30 s后，单层石墨烯发生中等程度的损伤(ID/IG = 1.2)， n原子(吡啶)和o原子(混合)含量增加。在较长的处理时间内(20分钟)，处理面积呈放射状增加，石墨烯被破坏。总体而言，随着DBD源工作电压的增加，n原子含量增加。当仅用中性活性氮处理石墨烯时，n原子的含量和类型保持不变。因此，我们假设从DBD中导致吡咯烷N掺杂的主要反应物质是N(4S)和可能的N(2P)等中性物质。
