Abstract :
The development of green and easily regulated amphiphilic particles is crucial for advancing Pickering emulsion catalysis. In this study, lignin particles modified via sulfobutylation were employed as solid emulsifiers to support Pd nanoparticles (NPs), thereby enhancing the catalytic efficiency of biphasic reactions. Sulfobutylation of lignin effectively adjusted the hydrophilic-hydrophobic balance, resulting in controlled emulsion types and droplet sizes. Pd NPs were loaded onto lignin with a 50% sulfobutylation ratio through the in situ reduction of active functional groups, further stabilized by the cross-linked network structure of lignin. In the hydrogenation of nitrobenzene, the Lig-50S-0.6Pd catalyst exhibited superior activity compared to traditional Pd/C catalysts, which is attributed to the high retention of active sites and increased interfacial area. This work underscores the potential for designing lignin-based amphiphilic particles and developing Pickering emulsion-enhanced reactions.

Abstract :
The development of diverse microstructures has substantially contributed to recent progress in high-performance electromagnetic wave (EMW) absorption materials, providing a versatile platform for the modulation of absorption properties. Exploring multidimensional microstructures and developing tailored and gentle strategies for their precise optimization can substantially address the current challenges posed by relatively unclear underlying mechanisms. Here, a series of 2D/1D heterogeneous NiO@PPy composites featuring hollow hierarchical microstructures are successfully synthesized using a straightforward strategy combining sacrificial templating with chemical oxidative polymerization. This strategy offers a facile and effective approach to fine-tune the microstructure by adjusting the thickness of the polypyrrole (PPy) coating. This enables the continuous optimization of the dielectric properties and specific microstructures to maximize EMW absorption. Remarkably, the optimized 2D/1D hierarchical hollow NiO@PPy composite demonstrates an ultrathin thickness of 2.3 mm, a wide effective absorption band spanning 5.89 GHz, and a strong absorption intensity of -71.65 dB at a minimal loading of only 10 wt.%. The proposed mild and controllable preparation strategy not only provides insights for further tailoring the optimal dielectric properties of specific structures to enhance the absorption capacity, but also enriches the exploration of the underlying absorption mechanisms from the perspective of microstructure regulation.

Abstract :
Ultrahigh-resolution polymer materials with good thermal stability and high interface contrast have a wide range of application prospects in photolithography and nanomanufacturing processes. Here, we report a series of comb-like homopolymers based on polystyrene sulfonate imidazolium salts (PSSM-(i)imi), achieving efficient self-assembly under solvent-free conditions and obtaining sub-3 nm hexagonally packed cylinders and sub-4 nm lamellar nanopatterns with high interface contrast. The sulfonic acid groups in the main chain of the homopolymers are connected to imidazole groups containing hydrophobic alkyl side chains through acid-base mixed electrostatic interactions. The electrostatic interactions enhance the incompatibility between the two functional groups, while the alkyl side chain can precisely control the domain spacing and nanostructure of the pattern, regardless of their molecular weight. Through the effect of temperature fields, the thermal stability and spatial orientation of the homopolymer nanostructures were further studied, promoting the practical application of nanopatterned materials.

Abstract :
Covalent organic frameworks (COFs) are crystalline, porous semiconductors that have attracted significant interest in photocatalysis. The double chain edge structure of one-dimensional (1D) COFs enhances stability and minimizes energy loss, while varying linkage orientations create diverse optical band gaps and charge transfer properties. However, dimensional and isomeric COFs are rarely explored in photoinduced electron transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization, leaving their structure-activity relationships unclear. Herein, we synthesized 1D TA-COF, 1D TF-COF, 2D TA-COF, and 2D TF-COF to evaluate their behavior in oxygen-tolerant PET-RAFT polymerization. Notably, 1D TA-COF demonstrated optimal photocatalytic performance (79.4%, 16 h) owing to efficient charge separation, while isomeric 1D TF-COF exhibited lower productivity (41.5%) due to hindered electron transfer. Additionally, 2D TF-COF outperformed 2D TA-COF (51.0% vs. 36.7%, 16 h), highlighting the considerable impacts of dimension and isomerism on performance, with dimension playing a more dominant role due to the electron delocalization characteristics determined by topological structure.

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 development of multifunctional therapies with targeted release materials is desirable for overcoming the high aggressiveness and poor prognosis of triple-negative breast cancer (TNBC). Herein, we have designed a self- assembled supramolecule (BSD), in which SWNTs can be wrapped by triple-helix beta-Glucan (BFP) in a self- assembled manner, and doxorubicin (DOX) is attached onto SWNTs by means of it-stacking and hydrophobic interactions with high drug encapsulation efficiency (89.3 %). BFP could significantly improve the dispersion and stability of SWNTs and DOX, and reduce toxicity. BSD provides a drug-targeting mechanism due to the pH- responsive and near-infrared radiation (NIR) thermal-responsive release of DOX, and BSD displayed excellent photo-thermal conversion effect and cyclic stability, and exhibited higher antitumor activity under near-infrared radiation than chemotherapy alone. Photothermal therapy mainly blocked the synthesis of nutrients required for tumor DNA replication, while chemotherapy markedly induced oxidative stress production, which ultimately exacerbated DNA damage of tumor cells. As a result, the combined effect of chemo-photothermal therapy ultimately promote tumor cell apoptosis and suppress the growth of primary tumor and metastasis to the lungs in vitro and in vivo. This study provides a promising pH/NIR thermal-responsive sustained prodrug for combined chemo-photothermal therapy against aggressive triple negative breast cancer in practical therapy.

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 :
Electronic grade hydrogen peroxide plays a crucial role in the fabrication of large-scale integrated circuits. However, hydrogen peroxide prepared by the anthraquinone method contains impurities such as lead ions (Pb2+) and phosphate, which can seriously affect the yield of the circuit. Traditional adsorbent materials have difficulty in solving the problem of simultaneous adsorption of trace anions and cations in hydrogen peroxide due to the single adsorption site and poor adsorption kinetics. In this study, UiO-66-NH2 was prepared by introducing a -NH2 group on the terephthalic acid ligand, and a series of hybrid matrix hollow fiber membranes with different UiO-66-NH2 contents were prepared by loading it on polysulfone (PSF). This initiative not only improved the pore size and water flux of hollow fiber membranes but also enhanced the removal efficiency of ions from hydrogen peroxide solution, thereby facilitating practical application. Among them, UiO-66-NH2@PSF-1.5 showed the best adsorption of phosphate and lead ions with adsorption capacities of 3.099 and 2.160 mg g(-1) and reached the removal efficiency of 67.1 and 60.1%, which fully confirms the practicability in the purification of electronic chemicals. This work innovatively proposes that UiO-66-NH2@PSF hybrid matrix hollow fiber membranes have great potential as simultaneous adsorbents for cations and anions in the efficient purification of electronic grade solvents.

Abstract :
To address the challenge of controllable and precise regulation of the phase behavior of block copolymers, this study proposes a novel strategy to regulate the self-organization behavior of PS-P2VP block copolymers through supramolecular self-assembly. PS-P2VP was synthesized via the RAFT method, and three POSS molecules with different non-covalent interactions were synthesized and used to form complexes with the PS-P2VP copolymers. Characterization techniques such as NMR, GPC, FT-IR, TGA, DSC, SAXS, and SEM, along with theoretical methods, were employed to analyze the impact of POSS on the phase behavior of PS-P2VP. The results demonstrate that POSS is particularly effective in modulating the self-assembled phase behavior in the lamellar phase of block copolymers, with BPOSS-Cl showing the most significant modulation, enabling the complexes to achieve third-order peaks in SAXS measurements. This conclusion is further supported by theoretical calculations. The study not only reveals the mechanism by which POSS regulates the self-assembly behavior of PS-P2VP but also provides a promising direction for advancing autonomous phase selection in block copolymers.

Abstract :
The development of dual-functional composite materials that integrate efficient electromagnetic wave (EMW) absorption and thermal conductivity is a crucial advancement in addressing the issues of electromagnetic pollution and heat accumulation in electronic devices. In this work, NixCoy-C/PAM hydrogels derived from mixed metal MOF-74 were successfully fabricated by in situ radical polymerization with the assistance of an external magnetic field. The properties of NixCoy-C/PAM were optimized by varying the ratios of cobalt and nickel metals as well as their oxides, thereby providing opportunities for the creation of advanced electromagnetic wave absorbers. When the Ni/Co ratio was increased to 1:1, Ni1Co1-C/PAM demonstrated superior EMW absorption performance at a filler ratio of 3 wt%. This configuration exhibited a minimum reflection loss of -57.8 dB at 8.64 GHz with a thickness of 3.6 mm, alongside an effective absorption bandwidth extending up to 5.81 GHz with a thickness of 2.3 mm. Furthermore, magnetic orientation within the filler facilitated enhanced heat transfer by establishing high-efficiency thermal conductive pathways. This study offers valuable insights into designing polymer composites characterized by improved thermal conductivity and robust EMW absorption capabilities.
