Abstract ：
Oil/water separation of emulsion stands as one of the most arduous and challenging aspects in oily wastewater treatment which represents a perennial trouble for humanity. Herein, positively charged hydrophobic polymer foams (PCHPFs) were fabricated by water-in-oil (W/O) high internal phase emulsion (HIPE) polymerization followed by quaternization, employing 4-vinylbenzyl chloride (VBC) and 4-tert-butylstyrene (tBS) as the comonomers. The quaternization degree of PCHPFs which can be adjusted by varying the VBC/tBS ratio has an important influence on the emulsion separation performance based on the charge demulsification mechanism. The porous morphologies of PCHPFs were revealed by SEM. The successful fabrication of PCHPFs was confirmed by FTIR and XPS. As VBC/tBS ratio increased from 0.5:1-5:1, the emulsion separation efficiency of PCHPFs first increased to a maximum of 95.9 % at 2:1 and then decreased. Additionally, the PCHPFs demonstrated robust hydrophobicity (water contact angles > 143 degrees), exceptional oil-water selectivity, remarkable oil-water separation capability, coupled with a certain absorption capacity for various oils and organic solvents (5-14 g/g). Given these advantages, PCHPFs are anticipated to emerge as an ideal solution for emulsion separation. Most importantly, the methodology for generating PCHPFs via quaternization in this research offers an innovative avenue in the design of charge demulsification materials.

Abstract ：
Reduced graphene oxide (rGO) is a type of significant electrode material for flexible supercapacitor due to its outstanding mechanical and electrochemical properties. However, low oxidative activity of rGO remains a constraint in developing such devices. In this study, partially reduced graphene oxide (prGO) with enhanced oxidative activity was prepared, into which carbon nanotubes (CNTs) were incorporated to prepare CNT/prGO film with a loosened structure by filtration. Then, polyaniline (PANi) was deposited onto the surface of CNT/prGO composite through in-situ polymerization, resulting in CNT/prGO/PANi composite film. The morphology and structure were investigated via SEM, TEM, XPS, etc. The influences of CNT/prGO ratio and aniline polymerization time on the morphology and electrochemical performance were studied. The electrochemical test results indicated that the CNT/prGO/PANi composite exhibited the best electrochemical performance under the conditions of aniline polymerization for 4 h and CNT/prGO ratio of 3:10. Further increasing the polymerization time or CNT/prGO ratio resulted in short rods-like PANi coated CNTs which merge to form a large flake morphology. The optimized CNT/prGO/PANi demonstrated a specific capacitance of 706 mF cm(-2) (similar to 353 F g(-1)) at 0.1 mA cm(-2), with the specific capacity retaining 78 % of its original value after 3000 charging/discharging cycles at 1 mA cm(-2). Flexible supercapacitors fabricated with CNT/prGO/PANi as electrode exhibited an energy density of 245 mW h cm(-2) at 124 mW cm(-2). These results suggest that flexible solid-state supercapacitors based on CNT/prGO/PANi hold promising potential for energy storage applications.

Abstract ：
The development of modern electronic devices necessitates the creation of materials that exhibit both excellent thermal conductivity and high electromagnetic wave absorption performance. This study focuses on the synthesis of a dual-functional composite material, Co-C@PDA@BN, by incorporating boron nitride (BN) onto a metal-organic framework (MOF)-derived Co-C core through the strong adhesion properties of polydopamine (PDA). The heterogeneous structural interface enhances interfacial polarization, thereby optimizing wave absorption. The thermal conductivity can be improved by adjusting the ratio of Co-C to BN. A composite with a Co-C to BN ratio of 1 : 5 shows a minimum reflection loss of -55.3 dB at 5 wt% and a thermal conductivity of 0.396 W m-1 K-1, while a ratio of 1 : 20 achieves a thermal conductivity value of 0.464 W m-1 K-1 with a minimum reflection loss of -44.9 dB, demonstrating the facile tunability of these two properties. This work provides a promising pathway via heterostructure design to balance thermal conductivity and wave absorption characteristics, which may offer guidance for advancing electronic device technology.

Abstract ：
The electrochemical reduction of CO2 to produce high-value multicarbon products represents a challenging yet highly desirable process, particularly due to the inefficient C-C coupling observed in current electrocatalysts. In this study, Cu2+ and Co2+ were introduced into ZIF-8 as precursors to synthesize a series of Co- and CuCo-doped carbon nanostructure materials with varying Co-to-Cu ratios. X-ray diffraction and X-ray photoelectron spectroscopy (XPS) analyses confirmed the successful doping of metal Co in the form of Co-N-x, while Cu was partly doped as nanoparticles attached to the carbon substrate surface and partly as single atoms forming Cu-N-x. Transmission electron microscopy and energy-dispersive X-ray spectroscopy analyses revealed uniform distribution of elemental Co and Cu on the carbon substrate, with Cu loaded as nanocluster on the surface. Linear sweep voltammetry tests indicated that Cu/CoCu-N-x-C composites exhibited enhanced reactivity toward CO2 reduction compared to other samples. At -0.19 V (vs RHE), the Faradaic efficiencies (FEs %) of C2H4, C2H6, CH4, CO, and H-2 over Cu/CoCu-N-x-C were 29.7, 8.6, 20.2, 9.8, and 31.5%, respectively. The influence of Co and Cu doping modes on the selectivity of electrocatalytic reduction products was investigated. Results showed that Cu/CoCu-N-x-C exhibited a higher FE of C-2 compared to Cu/Cu-N-x-C, with nearly 10 times higher C-2 current density. Mechanistic insights from acid-etching experiments and XPS revealed a synergistic interaction between metallic Co and Cu, promoting the generation of multicarbon products. Co-N-x improved *CO coverage, facilitating subsequent C-C coupling on neighboring Cu-N-x. Additionally, CH4 production was attributed to the (111) crystalline facets in the Cu nanocluster and isolated Cu-N-x. Overall, this research provides an important understanding of the creation of straightforward and effective catalysts for the reduction of CO2. It holds considerable potential for the production of hydrocarbons using carbon dioxide.

Abstract ：
A latent microencapsulated catalyst (LMC) is a promising material to prepare one-component silicone rubber curing in industry. In this study, polystyrene (PS) with varying molecular weights and narrow molecular weight distributions (1.07-1.44) was meticulously synthesized via atom transfer radical polymerization (ATRP). Then, the synthesized PS was used as the wall material and a Karstedt catalyst was used as the core material to prepare different sizes of LMCs with a core content of about 20 wt % by a solvent evaporation method. The chemical structure, surface morphology, and core content of the prepared LMCs were characterized. Furthermore, the curing characteristics of one-component silicone rubber with different LMCs were investigated. Comparative analysis revealed that LMCs prepared from PS derived via ATRP exhibited superior attributes compared to those generated using commercially available PS, including a smaller particle size, more concentrated particle size distribution, heightened thermal responsiveness to temperature fluctuations, accelerated curing rate, and prolonged room temperature latency. Notably, the ATRP-derived LMCs demonstrated exceptional stability, ensuring steady storage with a latent period exceeding 2 months at room temperature.

Abstract ：
Recovery and separation of anthropogenic emissions of electronic specialty gases (F-gases, such as CF4 and SF6) from the semiconductor sector are of critical importance. In this work, the hierarchical porous UiO-66-Br-2@PS/DVB-packed column was constructed by a high internal phase emulsions strategy. UiO-66-Br-2@PS/DVB exhibits a superior selectivity of CF4/N-2 (2.67) and SF6/N-2 (3.34) predicted by the IAST due to the diffusion limitation in the micropore and the gas-framework affinity. Especially, UiO-66-Br-2@PS/DVB showed significant CF4 and SF6 retention and enabled the successful separation of CF4/N-2 and SF6/N-2 with a resolution of 2.37 and 8.89, respectively, when used as a packed column in gas chromatography. Compared with the Porapak Q column, the HETP of the UiO-66-Br-2@PS/DVB-packed column decreased and showed good reproducibility. This research not only offers a convenient method for fabricating a hierarchical porous MOF-packed column but also showcases the prospective utilization of MOFs for the separation of the F-gas/N-2 mixture.

Abstract ：
The long-term objective of tandem reaction is to investigate 'intelligent' tandem reaction systems akin to living cells. Here we've prepared an 'intelligent' droplet microreactor for the tandem reaction using droplet microfluidic technology constructing a photoresponsive microfluidic tandem reaction system. The method leverages a three-phase emulsion's 'two membranes and three phases' structure to segregate incompatible reagents, and introduces a stimulating surfactant to control the structure of this emulsion structure for intelligent reaction sequence control, enabling efficient, orderly tandem reaction within the same system. Validating this concept, we applied the droplet microreactor to the condensation-reduction cascade reaction, as envisioned, incompatible condensation and reduction reactions, were coordinated by cycling the UV light on /off for a smooth cascade reaction. Compared to batch reaction, the droplet microreactor showed sixfold catalytic efficiency enhancement and > 99 % reaction selectivity. Our work offers novel insights into realizing intelligent cascade reactions.

Abstract ：
A series of polymers are simply synthesized by the copolymerization of vinyl functionalized polyhedral oligomeric silsesquioxanes (POSS) with vinylimidazole based linker by modulating the molar ratio of two monomers. The synthesized POSS-based polymers are capable of catalyzing the cycloaddition reaction of CO2 with a variety of epoxides at atmospheric pressure without solvent and co-catalyst, producing cyclic carbonates with conversion up to 97.1 %. Noteworthy, the reaction kinetics studies have demonstrated that the POSS-based polymers are able to significantly reduce the activation energy of cycloaddition reactions of CO2. In addition, as a heterogenerous catalysts, the POSS-based polymer can be recovered and recycled 5 times without reducing catalytic performance.

Abstract ：
In this work, a series of N-doped porous carbons (NPCs) are prepared via high internal phase emulsion (HIPE) template, followed by growing polyaniline (PANI) arrays and subsequent carbonization/activation. As evidenced by SEM and N2 absorption/desorption results, the NPCs have interconnected hierarchical porous structures with abundant micropores and mesopores inside. The morphology and porous structures of NPCs can be tuned by changing aniline concentration and polymerization time, respectively. With the increase of aniline concentration or polymerization time, the porous structure of NPC becomes more and more serried, however too high aniline concentration (>0.75 M) makes the porous structure become sparse, which is because excess PANI will nucleate itself and make it detach from the surface of NPC. As a result, the specific surface area (SSA) of NPCs first in-creases to 1769 m2/g and then decreases. Electrochemical performances of the obtained NPCs are evaluated in detail. The test results indicate that both aniline concentration and polymerization time have notable influence on the specific capacitance of NPCs. The specific capacitance of NPC obtained under optimized conditions reaches up to 241 F/g at 1 A/g with a retention ratio of 97.8% after 10, 000 cycles at a high current density, proving its excellent energy storage capability and cycling stability. In two-electrode system, the NPC provides an energy density of 27 Wh/kg at a power density of 400 W/kg and remains a high energy density of 19 Wh/kg at a high power density of 10002 W/kg.
