| 1 | Rolling up MXene sheets into scrolls to promote their anode performance in lithium-ion batteries显示文摘Although Ti3 C2 MXene sheets have attracted extensive attention in lithium-ion storage techniques,their restacking makes against and even hinders the Li ions diffusion within them,thereby decreasing the capacity as well as rate performance of conventional MXene anode.Here,for the first time,we roll up the Ti3 C2 Tx sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem.Thus,Ti3 C2 Tx scrolls as anode materials in lithium-ion batteries(LIBs)have higher capacity and better rate performance than Ti3 C2 Tx sheets.On the bases of these,high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti3 C2 Tx/Si composite scrolls.The addition of 10%silicon nanoparticles shows the best overall improvement among capacity,rate capability and cyclic stability for Ti3 C2 Tx scrolls. | Jianing Meng Fangfang Zhang Li Zhang Lingyang Liu Jiangtao Chen Bingjun Yang Xingbin Yan | 2020 | Journal of Energy Chemistry2020，29，7： | 4 |

| 7 | SORPTION OF PHENOL AND P-NITROPHENOL ONTO A WEAKLY ANION EXCHANGER: XPS ANALYSIS AND MECHANISM显示文摘X-ray photoelectron spectroscopy(XPS)was adopted to elucidate sorption mechanism of phenol and p-nitrophenol onto a weakly anion exchanger D301.The distribution of specific forms of tertiary amino group on D301 was obtained and effect of free tertiary amino group on phenol sorption onto D301 was discussed. The result indicated that the percent of the protonated tertiary amine group on polymeric matrix was much lower than the reference compound N,N-dimethylbenzylamine at an identical pH value in solution due to the much lower activity degree of hydrogen ion in inner resin phase than in the external solution. Less free amino group on D301 results in less sorption capacity of phenol and p-nitrophenol in an acidic solution. Under the experimental conditions both phenol sorption onto D301 can be explained as solid extraction and the distribution coefficient varies linearly with the content of free amino group on D301. | LI Xiaotao Pan Bingcai Pan Bingjun Zhang Weimin Meng Fanwei Chen Jinlong Zhang Quanxing | 2005 | Chinese Journal of Reactive Polymers2005，14，1： | 0 |
| 8 | Haversian bone-mimicking bioceramic scaffolds enhancing MSC-macrophage osteo-imunomodulation显示文摘The interaction between immune cells and bone forming cells plays a vital role in maintaining the homeostasis of the skeletal system,and is regulated by the three-dimensional structure of tissues.Whether the construction of biomaterials can activate or reproduce this spatial“cross-talk”between immune cells and bone forming cells in bone natural formation process is a prerequisite for successful fracture healing and bone regeneration.Herein,a bone marrow mesenchymal stem cells(MSCs)/macrophages-laden Haversian bone-mimicking bioceramic scaffold was successfully prepared through the biomimetic design of biomaterials and 3D printing technology.MSCs and macrophages were respectively distributed in the cancellous bone and Haversian canals of the scaffold to simulate the three-dimensional structure regulation of the cell spatial distribution and multiple intercellular interaction in natural bone tissue,and worked in concert to modulate the scaffold material-mediated osteo-immune microenvironment.The in vitro study revealed that the pro-inflammatory response of macrophages was more significantly inhibited when distributed with MSCs in the scaffolds at a cell ratio of 0.5:1 for co-culture,in comparison with multicellular culture at other ratios and unicellular culture.Meanwhile,MSCs exhibited the relatively high osteogenic potential,most likely via the activation of certain key signaling pathways mediated by macrophagesderived paracrine signaling mediators(OSM,BMP-2,and WNT10b).This work not only establishes a bionic platform for the regulation of multicellular osteo-immune response and regeneration but also offers a promising tissue-engineered biomimetic scaffold with improved immunomodulatory function for promoting bone tissue regeneration. | Bingjun Zhang Meng Zhang Yuhua Sun Mengmeng Li Fei Han Chengtie Wu | 2021 | Progress in Natural Science:Materials International2021，31，6： | 0 |
