Zuo, Linsen;Wu, Chenjiang;Tong, Lifen;Liu, Xiaobo research published 《 Improving interfacial properties of polyarylene ether nitrile/aramid fiber composite through hydrogen bonding interaction combined with molecular weight adjustment》, the research content is summarized as follows. Aramid fiber (AF)-reinforced composite is a material with high performance and great potential. In this work, polyarylene ether nitrile terminated with phthalonitrile (PEN-t-Ph) is used to modify the AF surface, and hydrogen bonds are formed between the AF and PEN-t-Ph resin, as shown by Fourier IR anal. Then modified AF (m-AF)/PEN-t-Ph composite laminate is prepared by hot-pressing, and the influence of mol. weight of PEN-t-Ph on performance of the m-AF/PEN-t-Ph composite laminate is studied. The PEN-t-Ph were named PEN-1, PEN-2, PEN-3 and PEN-4 according to mol. weight from large to small. And the mech. properties and interface compatibility of m-AF/PEN-n composite laminates initially increase and then decrease as the mol. weight of the PEN-t-Ph resin decreases. The m-AF/PEN-3 composite laminate has the best mech. performance with an interlaminar shear strength of 94 MPa that is 95% higher than the lowest values among the four samples. In addition, m-AF/PEN-3 has the best impact strength of 133.70 kJ/m², and in the dynamic mech. anal. test, m-AF/PEN-3 has a leading storage modulus with 62 GPa at 120°C which is 50 GPa higher than for the lowest sample. In general, the mol. weight of the PEN-t-Ph resin has a greater impact on performance of the m-AF/PEN-t-Ph composite laminates, and appropriate adjustment of mol. weight of the PEN-t-Ph resin will help improve the comprehensive performance of the m-AF/PEN-t-Ph composite laminate and provides a new way for preparing AF-reinforced materials.

Zhuo, Ming-Peng;He, Guang-Peng;Wang, Xue-Dong;Liao, Liang-Sheng research published 《 Organic superstructure microwires with hierarchical spatial organisation》, the research content is summarized as follows. Rationally designing and precisely constructing the dimensions, configurations and compositions of organic nanomaterials are key issues in material chem. Nevertheless, the precise synthesis of organic heterostructure nanomaterials remains challenging owing to the difficulty of manipulating the homogeneous/heterogeneous-nucleation process and the complex epitaxial relationships of combinations of dissimilar materials. Herein, we propose a hierarchical epitaxial-growth approach with the combination of longitudinal and horizontal epitaxial-growth modes for the design and synthesis of a variety of organic superstructure microwires with accurate spatial organization by regulating the heterogeneous-nucleation crystallization process. The lattice-matched longitudinal and horizontal epitaxial-growth modes are sep. employed to construct the primary organic core/shell and segmented heterostructure microwires. Significantly, these primary organic core/shell and segmented microwires are further applied to construct the core/shell-segmented and segmented-core/shell type′s organic superstructure microwires through the implementation of multiple spatial epitaxial-growth modes. This strategy can be generalised to all organic microwires with tailored multiple substructures, which affords an avenue to manipulate their phys./chem. features for various applications.

Zhuo, Ming-Peng;Su, Yang;Qu, Yang-Kun;Chen, Song;He, Guang-Peng;Yuan, Yi;Liu, Hao;Tao, Yi-Chen;Wang, Xue-Dong;Liao, Liang-Sheng research published 《 Hierarchical Self-Assembly of Organic Core/Multi-Shell Microwires for Trichromatic White-Light Sources》, the research content is summarized as follows. White-light-emissive organic micro/nanostructures hold exotic potential applications in full-color displays, on-chip wavelength-division multiplexing, and backlights of portable display devices, but are rarely realized in organic core/shell heterostructures. Herein, through regulating the noncovalent interactions between organic semiconductor mols., a hierarchical self-assembly approach of horizontal epitaxial-growth is demonstrated for the fine synthesis of organic core/mono-shell microwires with multicolor emission (red-green, red-blue, and green-blue) and especially organic core/double-shell microwires with radial red-green-blue (RGB) emission, whose components are dibenzo[g,p]chrysene (DgpC)-based charge-transfer (CT) complexes. In fact, the desired lattice mismatching (∼2%) and the excellent structure compatibility of these CT complexes facilitate the epitaxial-growth process for the facile synthesis of organic core/shell microwires. With the RGB-emissive substructures, these core/double-shell organic microwires are microscale white-light sources (CIE [0.34, 0.36]). Besides, the white-emissive core/double-shell microwires demonstrate the fascinating full-spectrum light transportation from 400 to 700 nm. This work indeed opens up a novel avenue for the accurate construction of organic core/shell heterostructures, which provides an attractive platform for the organic integrated optoelectronics.

Zhu, Ruomeng;Zhang, Pengling;Zhang, Xinxin;Yang, Mei;Zhao, Ruiqi;Liu, Wei;Li, Zhongyue research published 《 Fabrication of synergistic sites on an oxygen-rich covalent organic framework for efficient removal of Cd(II) and Pb(II) from water》, the research content is summarized as follows. A key matter in heavy metal removal technol. is to develop the adsorbents with efficient adsorption sites. In this study, an oxygen-rich covalent organic framework (JUC-505) was functionalized by carboxyl (-COOH) groups to form synergetic effects aiming for the removal of Cd(II) and Pb(II) ions. JUC-505-COOH shows a high Cd(II) uptake of 504 mg·g^-1 surpassing most of the reported porous adsorbents. Meanwhile, the kinetics study shows a rapid adsorption process at a high initial concentration (100 mg·L^-1), and the equilibrium can be reached within 5 min. We investigated the adsorption mechanism in-depth by d. functional theory calculations, proving the synergistic effects of surface complexation and hydrogen-bond, which are from the post-modified -COOH groups and the in-situ oxygen atoms of JUC-505, resp. Moreover, under the interference of common ions in natural water, the removal efficiency of Cd(II) is almost insusceptible, which sheds lights on the potential for the application in the natural water purification In addition, the Pb(II) uptake (559 mg·g^-1) and the adsorption kinetics also surpass most of the reported porous adsorbents.

Zhu, Lei;Liang, Gaolei;Guo, Chuanpan;Xu, Miaoran;Wang, Minghua;Wang, Changbao;Zhang, Zhihong;Du, Miao research published 《 A new strategy for the development of efficient impedimetric tobramycin aptasensors with metallo-covalent organic frameworks (MCOFs)》, the research content is summarized as follows. Two bimetallic CoNi-based metallo-covalent organic frameworks (MCOFs) were prepared and explored as the sensitive platforms of impedimetric aptasensors for efficient detection of tobramycin (TOB). The two CoNi-MCOFs were constructed using metallophthalocyanine tetra-amine (MPc-TA, M = Co²⁺ or Ni²⁺) and 4,4′-(1,10-phen-anthroline-2,9-diyl) dibenzaldehyde (PTD) as building units and further coordinating to the secondary metal ions (Ni²⁺ or Co²⁺) by phenanthroline. Interestingly, the immobilization ability of CoPc-TA-PTD(Ni) to TOB-targeted aptamer is higher than that of NiPc-TA-PTD(Co) due to its stronger binding interactions to aptamer. As a result, the CoPc-TA-PTD(Ni)-based aptasensor shows the superior TOB detection ability, giving a low detection limit of 0.07 fg mL^-1 and satisfied sensing performances, such as high selectivity, good reproducibility, and excellent stability. Also, the aptasensor shows the acceptable applicability for detecting TOB in milk or chicken egg. This MCOFs-based sensing strategy could be extensively applied to detect other analytes by anchoring the corresponding probes.

Zhou, Wu;Ye, Zhiping;Nikiforov, Anton;Chen, Jun;Wang, Jiade;Zhao, Liang;Zhang, Xiuwen research published 《 The influence of relative humidity on double dielectric barrier discharge plasma for chlorobenzene removal》, the research content is summarized as follows. The influence of relative humidity on the elec. characteristics, the generation of the active species and the chlorobenzene removal performance was studied. The results show that both the peak-to-peak current and the discharge power decreased with the increase of relative humidity under the same peak-to-peak voltage. A reduction of electron temperature was observed with the addition of water vapor, affecting the electron impact processes. It was observed that excited states of N2 and O were affected by the water due to the quenching effect. A decrease of chlorobenzene removal efficiency was achieved from 81.7% to 70.7% as the increase of humidity. However, carbon balance anal. depicts the yields of CO2 in humid air were higher than that in dry air due to the help of radical OH, especially in RH = 40%, and highest energy efficiency with 4.4 g kW-1 h-1 was also achieved at RH = 40%. Chlorine balance indicates that the product HCl is more easily generated in the presence of H2O. A difference in the chlorobenzene degradation pathway was revealed. Fewer kinds of benzenoid byproducts were found in dry air, which was in agreement with the plasma diagnostics results. Radicals generated in humid air promoted the total oxidation process, resulting in fewer kinds of ring-open byproducts and higher CO2 yield.

A novel, environmentally friendly electrocatalytic process was developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing alkali halide salts. The gem-dihalides had the same or different halogens on the same carbon, depending on the reactant and inorganic halide salt used. An electron-withdrawing group, such as carbonyl, located at the α-site of mono-halogenated carbon, was essential to the reaction. The electrosyntheses were performed under ambient conditions without inert gas protection and displayed yields of about 80%. This method avoided the classical haloform elimination reaction. However, when the aqueous solution contained NaOH, two α-mono-halide ketone mols. had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination.
