PAW is considered a novel replacement of nitrogen fertilizers for sustainable agriculture. The process optimization for a pinhole plasma jet system (i.e., air flow rate and discharge time) to produce PAW with high reactive nitrogen species content and its application in microgreen production was investigated using response surface methodology. According to optimal conditions (i.e., an air flow rate of 5.0 L/min and a discharge time of 240 min), the highest NO3– (668.16 mg/L) and NO2– (60.59 mg/L) were obtained. Broccoli and radish microgreens treated with optimized PAW show higher growth attributes, such as germination percentage and fresh weight, compared to the control treatment. Additionally, the total protein content of both microgreens was significantly increased under optimal PAW, whereas no significant effects were exhibited in total phenolic compounds and antioxidant capacity. The stability of properties of the optimized PAW over 30 days of storage was determined, which is critical for preserving its effectiveness. This study confirms the ability of pinhole plasma jet technology to produce PAW with improved RNS components, as well as the efficacy of PAW in microgreen growing, taking a step towards its broader use in sustainable agriculture.

This work developed low-temperature and environmentally friendly hydrothermal carbonization approach for synthesizing small-sized carbon nanospheres [C(s) Ns]. It is demonstrated that C(s) Ns act as an efficient supporting material, thereby enhancing the sensor performance of Cu nanocrystals. Compared to pure Cu, the C@Cu Ns show enhanced sensor performance toward glucose, sodium nitrite, and formaldehyde. A comprehensive analysis was carried out to investigate the mechanism of enhanced sensor performances. Furthermore, the effects of Cu loading rates and the sizes of C Ns on sensor performance were systematically examined. In alkaline solutions, the sensitivity of C(s)@Cu-8% [ C(s) Ns with Cu 8 at% loading rate] in detecting glucose and formaldehyde was 1.94-fold and 3.06-fold higher than that of Cu nanocrystals, respectively. In neutral solutions, the sensitivity of C(s)@Cu-8% for detecting NaNO2 was 3.49-fold higher than that of Cu nanocrystals. As applied in actual substances, the obtained C(s)@Cu Ns could achieve the detection of NaNO2 in aqueous solutions and sugar content in Nescafé. This work introduced an economical sensor that features multifunctionality and enhanced performance, the utilization efficiency for Cu nanocrystals was enhanced while maintaining cost-effectiveness. Both the requirements for high-concentration glucose and nitrite detection were addressed.

Atrial fibrillation (Afib) presents significant public health challenges due to its complex mechanisms and elevated risks of stroke and heart disease. This study employs 3D fast-paced organoid models derived from human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to investigate mitochondrial dysfunction and cardiac fibrosis in Afib at the molecular level. Rapid pacing at 3 Hz for 24 h triggered a 50 % decline in peak contraction amplitude and a 55 % reduction in contraction velocity. Multi-omics profiling revealed pronounced mitochondrial injury—succinate dehydrogenase sub-units SDHA–D decreased by 35–60 % and the master regulator PGC-1α fell 48 % together with a 2.3-fold increase in cytosolic cytochrome-c. Profibrotic signalling was activated in parallel (AGTR1 was up-regulated 2.1-fold, TGF-β1 was up-regulated 2.5-fold), driving extracellular-matrix accumulation (collagen-I and α-SMA levels rose 1.9- and 2.2-fold, respectively). Public Gene Expression Omnibus (GEO) datasets further validated the clinical relevance of our model; the organoid transcriptional fingerprint correlated strongly with human atrial-tissue fibrosis signatures (R = 0.71, p < 0.001; GSE128188), highlighting its translational value. Collectively, these quantitative data demonstrate that 3-D fast-paced organoids recapitulate both the functional impairment and synchronous mitochondrial-fibrotic remodeling characteristic of early Afib. Taken together, coupling high-resolution functional metrics with multi-omics read-outs elevates cardiac-disease modelling and can accelerate the development of targeted therapies for atrial fibrillation.
心房颤动（Afib）由于其复杂的机制和卒中和心脏病的高风险，提出了重大的公共卫生挑战。本研究采用人类诱导的多能干细胞来源的心肌细胞（hiPSC-CMs）衍生的3D快节奏类器官模型，在分子水平上研究Afib的线粒体功能障碍和心脏纤维化。以3hz频率快速起搏24小时，可导致收缩峰值幅度下降50%，收缩速度下降55%。多组学分析显示，线粒体损伤-琥珀酸脱氢酶亚基SDHA-D下降了35 - 60%，主调节因子PGC-1α下降了48%，胞浆细胞色素-c增加了2.3倍。促纤维化信号被平行激活（AGTR1上调2.1倍，TGF-β1上调2.5倍），驱动细胞外基质积累（胶原- i和α-SMA水平分别上升1.9倍和2.2倍）。公共基因表达综合（GEO）数据集进一步验证了我们的模型的临床相关性；类器官转录指纹图谱与人心房组织纤维化特征密切相关(R = 0.71, p <；0.001;GSE128188)，突出了其翻译价值。总的来说，这些定量数据表明，3-D快节奏类器官概括了早期房颤的功能损伤和同步线粒体-纤维化重构特征。综上所述，将高分辨率功能指标与多组学读数相结合可以提高心脏病建模，并可以加速心房颤动靶向治疗的发展。

A droplet-based microfluidic device is used to generate multicellular tumor spheroids from A459 cells and alginate hydrogel. Then, they are settled in multiple chambers of a microfluidic platform for conducting high-throughput drug screening assays in different drug delivery conditions. The chambers of this platform are connected to a side channel, which can be used to control drug delivery to tumor models and culture endothelial cells using a hydrogel-free method. Drug delivery is also simulated numerically in different conditions, and the results reveal that the trend of drug internalized concentration in tumor cells can replicate well as the drug is delivered to tumor spheroids through the side channel. Finally, cytotoxicity assays are conducted in different drug delivery conditions using zinc oxide nanoparticles as anti-cancer agents. The results reveal that cell viability depends on the concentration of nanoparticles and the drug delivery method employed. Moreover, the highest level of drug resistance is obtained as the drug is delivered through the side channel in the proposed co-culture model. This model mimics well in vivo drug delivery conditions and can be established easily for preclinical drugtesting applications.

High aspect ratio dielectric etching can lead issues such as pattern distortion and twisting due to uneven polymer deposition on the sidewalls of high aspect ratio dielectric structures. In this study, to reduce charge related issues during the etching of high aspect ratio dielectric structure using a capacitively coupled plasma (CCP) etcher, as a showerhead electrode material, W instead of conventional Si was used and the effect of W inclusion to the polymer layer formed on the sidewall of the etched feature on the etch characteristics of a high aspect ratio SiO2 etching was investigated and compared with the conventional Si showerhead electrode by DC-biasing the electrodes. The results showed that the addition and increase of DC voltage to both electrodes improved etch selectivity of SiO2 over amorphous carbon layer (ACL). In the case of W showerhead electrode, DC-bias voltage to the electrode improved the pattern distortion due to the charge removal in the polymer formed at the SiO2 sidewall by the inclusion of W. It is believed that our findings provide valuable insights into the intricate interplay between electrode material reactivity and the resulting etching characteristics in CCP-based high aspect ratio etching processes.

On-road waste gas generally includes two categories: dynamic automobile exhaust and static asphalt volatile organic compounds (VOCs). The measures for purifying automobile exhaust can start from two aspects: automobiles and roads. This article mainly summarizes the application and main findings of commonly used TiO2 based materials for road exhaust treatment in cement and asphalt pavements. The application methods mainly focus on mixing, coating, and spraying, and summarizes the existing problems and development trends of this technology. The research on asphalt VOCs emission reduction mainly reviews the emission characteristics, evaluation methods, and emission reduction technologies of asphalt VOCs. The emission reduction technologies mainly include warm mixing technology and VOCs inhibitors, and some appropriate suggestions were provided. Finally, based on a profound understanding of on-road exhaust purification and VOCs emission reduction technologies, design of ’on-road waste gas integrated governance’ was proposed. This design can effectively and synchronously reduce the waste gas in the road area, achieving efficient collaborative treatment of on-road waste gas.

Novel films from recycled high-density polyethylene (HDPEr) were decorated with two photocatalysts: black TiO2 (B-TiO2) and Ag-loaded black TiO2 (B-TiO2-Ag). B-TiO2 synthesis and Ag deposition were achieved through chemical reduction of their respective precursors. The films were prepared via extrusion and compression molding, with two photocatalyst incorporation methods evaluated: direct addition during extrusion and film immersion into aqueous photocatalyst suspensions, including plasma pre-treatment. The latter introduced polar functional groups, enhancing nanoparticle adhesion to the film surface. Results confirmed successful Ag deposition on B-TiO2 via chemical reduction, with anatase reduction using NaBH4 increasing Ti3+ sites. Interestingly, two oxidation states of Ag were detected in B-TiO2-Ag. However, nanoparticle aggregation occurred during extrusion, likely due to poor compatibility between the polymer matrix and nanoparticles in terms of hydrophilicity, which plasma treatment mitigated. Regarding mechanical properties, nanoparticle incorporation via extrusion improved the Young’s modulus. Moreover, plasma-treated films exhibited significantly enhanced photocatalytic activity, leading to NOx abatement. In standardized tests, films with B-TiO2 and B-TiO2-Ag achieved NOX removal rates of 30.17 % and 40.80 %, respectively. This innovative approach valorizes HDPEr, offering a sustainable strategy for developing building materials that contribute to atmospheric pollution reduction.

Convection-enhanced delivery enables local administration of therapeutic agents to brain tissues by overcoming the challenges posed by the blood–brain barrier. However, its efficacy is limited by the lack of control over the delivery pathway. To address this, we propose infusion and iontophoresis for directional delivery of compounds in the brain (IIDD). This IIDD strategy involves the insertion of a cannula for drug infusion, along with two plate-shaped electrodes serving as the cathode and anode and positioned at predetermined sites in the brain. Iontophoresis generates an electrical path for controlled, directional transport of the injected compound. We tested it with gadobutrol, a clinically approved, negatively charged gadolinium-based contrast agent. We observed that increasing the duration of application of current (fixed current of 10 μA) facilitated significantly better migration of gadobutrol toward the anode than simple diffusion by convection-enhanced delivery alone. Simulation data derived from three-dimensional finite element modeling were consistent with the experimental findings. This further confirmed the feasibility of infusion and iontophoresis for directional delivery of compounds in the brain.

Nano-enabled surface coatings are increasingly used in consumer products; however, their full life-cycle impact remains poorly understood, particularly for materials such as nano-TiO2 that possess persistent ecotoxicity. A comprehensive life cycle assessment (LCA) was conducted for a laboratory-prepared surrogate of a commercial nano-TiO2-based car wax, integrating experimental measurements of material losses across synthesis, formulation, use, and disposal stages. The laboratory-scale synthesis of TiO2 via a modified sol–gel process revealed an average Ti recovery rate of 82 % during particle formation and only 44 % retention within the final wax matrix. The use-phase application results in a total loss of 98.9 %, with only 1.1 % of the initial TiO2 remaining on the coated surface. The life-cycle inventory was developed based on these empirical data and modeled using the ILCD 2011 midpoint+ and USEtox. While the midpoint results highlighted acetone and energy inputs as major contributors, USEtox integration revealed dramatic increases in endpoint indicators: freshwater ecotoxicity rose by 1,972 %, and non-cancer human toxicity by 4.9 %, driven by the inherent properties of nano-TiO2. This study offers one of the first integrated LCA frameworks that combines nanospecific experimental data with toxicity-adjusted impact modeling.

We present a straightforward method to fabricate free‐standing Ni(OH)2/NiOOH nanostructures by etching three‐dimensional nickel foam (NF) in HCl or H2SO4. Acid corrosion liberates Ni2+ ions that interact with Cl− or SO42− to form Ni hydroxide and oxyhydroxide phases directly on the NF substrate. The resulting hierarchical porous network uniformly embeds Ni(OH)2 and NiOOH throughout the conductive foam, providing abundant active sites for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) intermediates. This architecture enhances specific surface area, ionic mobility, electrical conductivity, and charge transfer efficiency, leading to superior catalytic performance. In alkaline water electrolysis, the Ni(OH)2/NiOOH electrode achieves 20 mA cm−2 at only 1.61 V in a two‐electrode setup and remains stable for over 12 h. It also demonstrates exceptional corrosion resistance in unpurified seawater compared to bare Ni and bimetallic NF. Comprehensive characterizations and electrochemical analyses confirm that the modulated surface structure, robust catalyst‐support interactions, and enhanced mass transport yield a highly efficient, durable, and cost‐effective bifunctional electrocatalyst. Our synthesis is scalable and environmentally benign for sustainable energy.
我们提出了一种简单的方法，通过在HCl或H2SO4中蚀刻三维泡沫镍（NF）来制备独立的Ni(OH)2/NiOOH纳米结构。酸腐蚀释放出Ni2+离子，与Cl−或SO42−相互作用，直接在NF衬底上形成氢氧化镍和氢氧化氧相。所得的分层多孔网络均匀地嵌入Ni(OH)2和NiOOH在导电泡沫中，为析氢反应（HER）和析氧反应（OER）中间体提供了丰富的活性位点。这种结构提高了比表面积，离子迁移率，电导率和电荷转移效率，从而导致优越的催化性能。在碱水电解中，Ni(OH)2/NiOOH电极在仅1.61 V的双电极设置下达到20 mA cm - 2，并保持稳定超过12小时。与裸Ni和双金属NF相比，它在未净化的海水中也表现出卓越的耐腐蚀性。综合表征和电化学分析证实，调制的表面结构、强大的催化剂-载体相互作用和增强的质量传递产生了高效、耐用和成本效益高的双功能电催化剂。我们的合成是可扩展的，对环境无害的可持续能源。
