0 M KOH) with a low overpotential of 260 mV to drive the benchmark current density of 10 mA cm-2 and Tafel slope of 62 mV dec-1, as well as long-term stability and high turnover frequency of 0.0641 s-1 at overpotential of 340 mV. The NiCo-LDH/ZnCo2O4 catalyst was found to perform significantly better than NiCo-LDH, ZnCo2O4, NiCo-LDH/Co3O4, Co3O4, and commercial RuO2 catalysts. The outstanding OER performance of NiCo-LDH/ZnCo2O4 catalyst, which may be attributed to the large specific surface area, accelerated mass and electron transport, and synergistic effect of multiple hybrid materials, makes it a promising catalyst for OER.Developing high-performance materials for the efficient removal of pharmaceutical contaminants from polluted water has gained tremendous attention but is still a huge challenge. Herein, various N-doped porous carbons (NPCs) were fabricated via a facile and solvent-free pyrolysis strategy by using a mixture of melamine, hexamethylenetetramine, Pluronic F 127, and ZnCl2 as precursor. The resulting NPCs featuring large specific surface areas (803-1002 m2/g) and high nitrogen content (3.79-5.24%) were used as efficient adsorbent for the capture of ibuprofen (IBP) from water. Due to the combination of abundant mesoporous and microporous structure as well as high nitrogen content, the adsorption equilibrium was achieved within 60 min and the adsorption capacity was calculated to be 113 mg/g. Furthermore, it was found that the adsorption capacity exhibited a good correlation with the nitrogen content. In addition, the adsorption capacity of the resulting NPC was well-maintained even after 4 cycles due to its superior stability. The study is expected to encourage the rational design and synthesis of versatile heteroatom-doped porous carbons for practical application in the field of environmental remediation.Harmful bacterial flourish with the increase in environmental pollution and pose a great threat to human health. Thus, developing new and efficient antibacterial materials is imperative to reduce the pollution caused by traditional sterilization materials and improve sterilization efficiency. In this study, a new photocatalytic antibacterial material was developed to achieve an efficient antibacterial effect. Ti3C2Tx@CuS composites were synthesized by simple hydrothermal method, by which copper sulfide (CuS) nanoparticles were anchored on the surface of Ti3C2Tx to sharply improve the photocatalytic its antibacterial ability. Ti3C2Tx@CuS exhibits excellent antibacterial activity against Escherichia coli and Staphylococcus aureus with bactericidal rates of 99.6% and 99.1%, respectively. SBE-β-CD solubility dmso Photoluminescence spectroscopy (PL), decay time PL, photocurrent test, electrochemical impedance spectroscopy and finite element method showed that the formation of Ti3C2Tx@CuS heterojunction promoted the separation of electrons and holes, improved the electron transport efficiency, and elevated the generation of reactive oxygen species. Moreover, Ti3C2Tx@CuS has a stronger photothermal effect and causes more heat release than CuS to improve antibacterial performance. The Ti3C2Tx@CuS heterojunction has a broad application prospect in the disinfection and antibacterial fields.In this paper, the novel 3D hollow Z-scheme heterojunction photocatalysts based on Bi2O3 and CoAl layered double hydroxides (Bi2O3@CoAl-LDHs) were prepared for efficient visible-light-driven photocatalytic ammonia synthesis. The synthesized nanohybrid exhibits excellent photocatalytic ammonia synthesis performance (48.7 μmol·L-1·h-1) and structural stability, which is primarily attributed to the fact that Z-scheme heterojunction significantly enhanced lifetime of photogenerated carriers (6.22 ns) and transfer efficiency of surface photogenerated electrons (72.5%). Strict control experiments and nitrogen isotope labeling results show that nitrogen and hydrogen in the produced ammonia come from nitrogen and water in the reactant respectively. Electron paramagnetic resonance (EPR) experiments and density functional theory (DFT) calculations further reveal that the built-in electric field due to the difference between Bi2O3 and CoAl-LDHs is the key to constructing the Z-scheme heterojunction. In addition, results of partial density of states (PDOS) show that Co in Bi2O3@CoAl-LDHs composite is the active site for photocatalytic N2 fixation.Understanding the molecular mechanisms underlying bubble-(bio)surfaces interactions is currently a challenge that if overcame, would allow to understand and control the various processes in which they are involved. Atomic force microscopy is a useful technique to measure such interactions, but it is limited by the large size and instability of the bubbles that it can use, attached either on cantilevers or on surfaces. We here present new developments where microsized and stable bubbles are produced using FluidFM technology, which combines AFM and microfluidics. The air bubbles produced were used to probe the interactions with hydrophobic samples, showing that bubbles in water behave like hydrophobic surfaces. They thus could be used to measure the hydrophobic properties of microorganisms' surfaces, but in this case the interactions are also influenced by electrostatic forces. Finally a strategy was developed to functionalize their surface, thereby modulating their interactions with microorganism interfaces. This new method provides a valuable tool to understand bubble-(bio)surfaces interactions but also to engineer them.Cytoplasmic availability of leukocyte lipid bodies is controlled by a highly regulated cycle of opposing biogenesis- and catabolism-related events. While leukocyte biogenic machinery is well-characterized, lipid body catabolic mechanisms are yet mostly unknown. Here, we demonstrated that nordihydroguaiaretic acid (NDGA) very rapidly decreases the numbers of pre-formed lipid bodies within lipid body-enriched cytoplasm of mouse leukocytes - macrophages, neutrophils and eosinophils. NDGA mechanisms driving leukocyte lipid body disappearance were not related to loss of cell viability, 5-lipoxygenase inhibition, ATP autocrine/paracrine activity, or biogenesis inhibition. Proteasomal-dependent breakdown of lipid bodies appears to control NDGA-driven leukocyte lipid body reduction, since it was Bortezomib-sensitive in macrophages, neutrophils and eosinophils. Our findings unveil an acute NDGA-triggered lipid body catabolic event - a novel experimental model for the still neglected research area on leukocyte lipid body catabolism, additionally favoring further insights on proteasomal contribution to lipid body breakdown.As an extreme type of partial auditory deprivation, single-sided deafness (SSD) has been demonstrated to lead to extensive neural plasticity according to multimodal neuroimaging studies. Among them, resting-state functional magnetic resonance imaging (rs-fMRI) offers valuable information on functional connectivities (FCs). However, most previous SSD rs-fMRI studies assumed that the extracted FC remains stationary during the entire fMRI scan and neglected dynamic functional activities. Existing fixed window-based dynamic FC analysis also ignores dynamic functional activities under different temporal terms. Additionally, due to the cost constraints of using MRI machines, using data-driven methods for unbiased hypothesis investigations may require more effective sample data augmentation techniques. To tackle these challenges and problems together, in this study, we proposed a dynamic window with a random length and position to extract participants' dynamic characteristics under different temporal terms and to exemporal gyrus, amygdala, and orbital gyrus played significant roles. These findings suggest that networks and regions related to higher-order cognitive functions showed the most significant FC alterations in SSD, which may represent a compensatory collaboration of cognitive resources in SSD.Convolutional neural networks (CNNs) are state-of-the-art computer vision techniques for various tasks, particularly for image classification. However, there are domains where the training of classification models that generalize on several datasets is still an open challenge because of the highly heterogeneous data and the lack of large datasets with local annotations of the regions of interest, such as histopathology image analysis. Histopathology concerns the microscopic analysis of tissue specimens processed in glass slides to identify diseases such as cancer. link2 Digital pathology concerns the acquisition, management and automatic analysis of digitized histopathology images that are large, having in the order of 100'0002 pixels per image. Digital histopathology images are highly heterogeneous due to the variability of the image acquisition procedures. Creating locally labeled regions (required for the training) is time-consuming and often expensive in the medical field, as physicians usually have to annotatethe strongly annotated data. Classification performance is evaluated on the student model at the patch level (using the local annotations of the Tissue Micro-Arrays Zurich dataset) and at the global level (using the TCGA-PRAD, The Cancer Genome Atlas-PRostate ADenocarcinoma, whole slide image Gleason score). The teacher/student paradigm allows the models to better generalize on both datasets, despite the inter-dataset heterogeneity and the small number of local annotations used. The classification performance is improved both at the patch-level (up to κ=0.6127±0.0133 from κ=0.5667±0.0285), at the TMA core-level (Gleason score) (up to κ=0.7645±0.0231 from κ=0.7186±0.0306) and at the WSI-level (Gleason score) (up to κ=0.4529±0.0512 from κ=0.2293±0.1350). The results show that with the teacher/student paradigm, it is possible to train models that generalize on datasets from entirely different sources, despite the inter-dataset heterogeneity and the lack of large datasets with local annotations.The UV/chlorine system has been regarded as an efficient oxidation technology for the removal of aqueous micropollutants. However, the roles of the possible radical species for this system on the elimination under environmentally relevant conditions/real waters were still largely unknown. Herein, the specific roles of radical species in the UV/chlorine oxidation degradation of gemfibrozil and naproxen as representative micropollutants were quantified by a steady-state kinetic prediction model considering the effects of water matrices. Overall, the model predicted results are consistent with the experimental data well. •OH and reactive chlorine species (RCS, such as Cl•, ClO•, and Cl2•-) contributions to gemfibrozil and naproxen degradation were water matrix specific. In pure water, both primary reactive species (i.e., •OH and Cl•) and secondary species ClO• dominated gemfibrozil and naproxen degradation, and their individual and the sum of the contributions to degradation rates reduced with pH increase of frocies in micropollutant removal by UV/chlorine oxidation under real water matrix.Sulfate radical (SO4•-) based oxidation shows great promise in wastewater treatment and subsurface remediation. For the first time, we demonstrated that SO4•- could induce the transformation of ammonium (NH4+) to nitrophenolic byproducts. Using high-resolution mass spectrometry in combination with 15N labeling, mono-nitro and di-nitro phenolic byproducts were identified in a sample containing 1 mM NH4+ and 10 mg/L natural organic matter (NOM) following heat activated peroxydisulfate (PDS) oxidation. At PDS dose of 1 mM, the formation of p-nitrophenol and 5-nitrosalicylic acid reached 0.21 and 0.30 μM, respectively, in 12 h and then decreased; the formation of 2,4-dinitrophenol and 3,5-dinitrosalicylic acid increased monotonically, reaching 0.37 and 0.62 μM, respectively, in 24 h. One-electron oxidation of NH4+ to form aminyl radicals (•NH2) was the first step of the transformation. link3 The reaction of •NH2 with oxygen was a key step in propagating radical chain reactions, leading to nitrogen dioxide radicals (NO2•) as a key nitrating agent.
