Summary: This study focused on the challenge of low dielectric materials in the communication industry. By designing and synthesizing fluorinated poly(arylene ether nitrile) containing carboxyl groups (PEN), and using MOF-3 as a nanoporous filler and crosslinker, cross-linked networks were constructed through simple heat treatment, significantly improving the overall performance of the composite films. The PEN-M-3 composite films exhibited a low dielectric constant of 2.33 at 1 MHz and a low water absorption of 0.126%. In addition, the composite films showed excellent thermal stability (T5% > 490 degrees C) and outstanding mechanical properties (tensile strength > 82 MPa). This research provides a new approach for the design and preparation of low dielectric materials.

Summary: Blending with high-performance thermoplastic polymer PEN can improve the mechanical properties and thermal stability of polybenzoxazine. When PEN loading was 30 wt%, the elongation at break value increased from 1.75% to 3.11%, and the tensile strength increased from 17.99 to 32.19 MPa. However, high loading of PEN led to phase separation and formation of isolated PEN spheres, resulting in a decrease in dielectric constant.

Summary: This paper investigates the electrical performance changes during continuous mode switching between fuel cell and electrolytic modes through experimental research. It is found that the voltage slightly decreases during mode switching, and the two-phase flow phenomenon is similar in different modes. Bubbles are generated and water is consumed in electrolytic mode, while liquid water gathers in the fuel cell mode. The cycle test results show that the voltage of both electrolytic cell and fuel cell decreases periodically, especially under high current density.

Summary: Rapid and accurate chemical composition identification is crucial in chemistry. Optical absorption spectrometry has limitations in identifying complex chemical compositions, especially in nano-scale research. In this study, a machine-learning-based method is developed to identify the compositions of metal nanoclusters (NCs) from featureless spectra. The method achieves good matches and low error values on optical absorption spectra that are difficult for humans to interpret. This work opens up possibilities for precise identification of nanomaterials based on their optical properties.

Summary: This paper proposes a hybrid model for studying the distribution of multi-point discharge plasma in large-scale spaces. The model divides the computational domain and computes separately using a hydrodynamic model and an ion mobility model. The simulation results are verified by experimental results. The study found that the charged particle concentration and current of the double-tip needle electrode are twice as high as those of the single-tip needle electrode. This model extends the computational area of the multi-point corona discharge finite element model and provides an effective means to study the plasma distribution generated by multiple discharge points in large-scale space.

Summary: The Chinese Loess Plateau has been severely impacted by anthropogenic activities, leading to minimal leopard sightings in recent decades. However, a recent discovery shows that the leopard population is recovering, offering hope for biodiversity conservation in human-dominated landscapes. By applying the concept of ecological networks, researchers identified key factors promoting leopard restoration and found that the connectivity of these networks positively influenced leopard survival. This study highlights the effectiveness of establishing ecologically connected habitats and the importance of using ecological networks for conservation planning in fragmented ecosystems.

Summary: Scientific papers are crucial for academic communication, but many of them lack in-depth research and present core content ambiguously, hindering the progression of science and technology. To address this challenge, the INTEGrity vERification (INTEGER) task is introduced to help researchers assess the integrity of their papers and verify the clarity of each knowledge unit. A multi-task learning model utilizing Tucker decomposition and span-level attention mechanism is proposed to accurately identify terms and their integrity. Experimental results show the effectiveness of the model.
