| 4 | Preparation of Different Lights Irradiated ZnSe/GSH QDs and Their Interaction with BSA显示文摘Using L-glutathione(GSH) as a capping agent,Zn Se/GSH quantum dots(QDs) were prepared under microwave irradiation and irradiated under dark, ultraviolet light and incandescent light, respectively. The properties and interaction of different lights irradiated ZnSe/GSH QDs and bovine serum albumin(BSA) were studied systematically. The fluorescence(FL) spectra results reveal that the quenching mechanism are all the static quenching in nature. The quenching constant(Ksv) and binding constant(K) value of different irradiated Zn Se/GSH QDs and BSA all increased with the change of light types from dark to incandescent light and UV light. The number of binding site(n) is close to 1 at different temperatures. The lighting types influence the enthalpy and entropy changes. The Fourier transform infrared(FTIR) spectra indicate that the light induced GSH ligand will facilitate photocatalytic oxidation on the surface of ZnSe/GSH QDs. The circular dichroism(CD)results show that the α-helicity content of BSA decreases from 60.34%, 59.31%, to 58.79% under UV lighting,incandescent lighting and dark conditions. The interaction results of different lights illuminated ZnSe/GSH QDs with BSA by CD spectra method matches well with that by FL and FTIR spectra. That is, the interaction of ZnSe/GSH QDs and BSA from strong to weak is UV light, incandescent light and dark in sequence. | 丁玲 HE Huan 李世迁 ZHOU Jin HUANG Kuntao CHENG Zhengzai GAUTHIER Mario | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 1 |
| 5 | Microwave Synthesis of CdTe/TGA Quantum Dots and Their Thermodynamic Interaction with Bovine Serum Albumin显示文摘The thioglycollic acid(TGA) as a capping agent, CdTe/TGA quantum dots(QDs) with excellent properties were synthesized under microwave irradiation. The TGA/Cd/Te molar ratios, reaction time, temperature and p H are the crucial factors for properties of QDs. The QDs were characterized by UVvis absorption and fluorescence spectra, transmission electron microscopy and Fourier transform infrared spectroscopy. The experimental results show that when the p H value is 11.5 and molar ratio of TGA:Cd:Te is 1.2:1:0.4 at 100 ℃ heating for 15 min, the resulted QDs exhibit a high fluorescence quantum yield of 78%. The fluorescence full width at half maximum(FHMW) of QDs is around 23 nm. The products are spherical with average size of 3-5 nm. There is a strong coordination effect between TGA and Cd2+. Moreover, the results of interaction between as-made QDs and bovine serum albumin(BSA) suggest that the QDs-BSA binding reaction is a static quenching. The negative values of free energy(△G<0) suggest that the binding process is spontaneous, △H<0 and △S<0 show that hydrogen bonds and van der Waals interactions play a major role in the binding reaction between QDs and BSA. | 丁玲 PENG Zeze SHEN Weizhou LIU Tao CHENG Zhengzai GAUTHIER Mario 梁峰 | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，6： | 1 |
| 6 | Synthesis and Characterization of Poly(terephthalic acid-2,5-furandicarboxylic acid-1,8-octanediol) Copolyester显示文摘Terephthalic acid,2,5-furandicarboxylic acid and 1,8-octanediol were adopted as monomers and antimony trioxide as catalyst,and poly(terephthalic acid-2,5-furandicarboxylic acid-1,8-octanediol) copolyesters identified as PEOT-x,where x is the mole fraction of furandicarboxylic acid in the samples,were synthesized by direct esterification.The molecular structure of the copolyesters was characterized by FTIR and 1H NMR spectroscopy.Gel permeation chromatography (GPC),differential scanning calorimetry (DSC),and thermogravimetric analysis (TGA) were used to characterize the molecular weight,molar mass dispersity,glass transition temperature,and thermal stability of the copolyesters,respectively.The mechanical properties of the samples were also investigated.The number-average molecular weight (M_(n)) of the samples varies from 9 700-18 800 g/mol,and molar mass dispersity (■=M_(w)/M_(n)) from 2.15-3.34.The initial decomposition temperature of the copolyesters is in the 332-356 ℃ range,with maximum decomposition rates at 390-410 ℃,while the glass transition temperature (Tg) varies from 0-33 ℃.Mechanical test shows that PEOT-10 has the highest tensile strength,while PEOT-90 has the largest tensile modulus and elongation at break.The experimental results show that these copolyesters can be synthesized with relatively high molecular weights,good thermal stability,and fair mechanical properties,which makes them excellent replacements for commercial polyesters,such as PET,and these properties can be tuned through the relative amounts of biomass monomer 2,5-furandicarboxylic acid used in the reactions. | 程正载 CHENG Junpeng CHEN Jun XIONG Jing SUN Xin JIA Ruyan YUAN Beibei Gauthier Mario | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，4： | 1 |
| 7 | Preparation of Nitrogen-doped Carbon Dots from Coke Powder as a Fluorescent Chemosensor for Selective and Sensitive Detection of Cr (Ⅵ)显示文摘The nitrogen-doped carbon dots(N-CDs)were prepared by using coke powder as carbon source and one-step hydrothermal method.The N-CDs were studied as a fluorescent chemosensor for determining Cr(Ⅵ)in water.The selective,sensitive,reproducibility and stability of as-prepared N-CDs were investigated.The morphology,composition and properties of N-CDs were characterized by a series of methods.The fluorescence quenching of N-CDs by Cr(Ⅵ)was explored.The experimental results reveal that the obtained N-CDs have great hydrophilicity and strong luminescence properties,which demonstrates the successful doping of nitrogen into the CDs.The surface-active groups and emission wavelength range of CDs increase due to the electronegativity and electron donor effect of doping N atom.Furthermore,the N-CDs exhibit good photochemical properties for the detection of Cr(Ⅵ),including a wide linear range from 0.3 to 200μM(R^(2)=0.9935)and a low detection limit of 0.10μM at the signal-to-noise ratio of 3(S/N=3).Moreover,the N-CDs as a sensor was used successfully for Cr(Ⅵ)detection in real water samples with recovery rates of 99.9%-110.6%.This sensor also shows highly reproducibility and stability.The N-CDs fluorescent chemical sensor may be a potential candidate for applying in the field of other fluorescent chemical sensing,catalysis,photoelectric devices and other fields. | 孟娟 LI Shiqian 丁玲 ZHOU Chuang JIANG Rui ZHANG Qingtian CHENG Zhengzai GAUTHIER Mario HU Ya 伍林 | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，6： | 0 |

| 11 | Engineering homologous platelet-rich plasma,platelet-rich plasma-derived exosomes,and mesenchymal stem cell-derived exosomes-based dual-crosslinked hydrogels as bioactive diabetic wound dressings显示文摘The management of diabetic wounds remains a critical therapeutic challenge. Platelet-rich plasma (PRP) gel, PRP-derived exosomes (PRP-Exos), and mesenchymal stem cell-derived exosomes (MSC-Exos) have demonstrated therapeutic potential in wound treatment. Unfortunately, their poor mechanical properties, the short half-lives of growth factors (GFs), and the burst release of GFs and exosomes have limited their clinical applications. Furthermore, proteases in diabetic wounds degrade GFs, which hampers wound repair. Silk fibroin is an enzyme-immobilization biomaterial that could protect GFs from proteases. Herein, we developed novel dual-crosslinked hydrogels based on silk protein (SP) (sericin and fibroin), including SP@PRP, SP@MSC-Exos, and SP@PRP-Exos, to promote diabetic wound healing synergistically. SP@PRP was prepared from PRP and SP using calcium gluconate/thrombin as agonist, while SP@PRP-Exos and SP@MSC-Exos were derived from exosomes and SP with genipin as crosslinker. SP provided improved mechanical properties and enabled the sustained release of GFs and exosomes, thereby overcoming the limitations of PRP and exosomes in wound healing. The dual-crosslinked hydrogels displayed shear-induced thinning, self-healing, and eradication of microbial biofilms in a bone-mimicking environment. In vivo, the dual-crosslinked hydrogels contributed to faster diabetic wound healing than PRP and SP by upregulating GFs expression, down-regulating matrix metalloproteinase-9 expression, and by promoting an anti-NETotic effect, angiogenesis, and re-epithelialization. Hence, these dual-crosslinked hydrogels have the potential to be translated into a new generation of diabetic wound dressings. | Bianza Moise Bakadia Abeer Ahmed Qaed Ahmed Lallepak Lamboni Zhijun Shi Biampata Mutu Mukole Ruizhu Zheng Mazono Pierre Mbang Bi Zhang Mario Gauthier Guang Yang | 2023 | Bioactive Materials2023，，10： | 0 |

| 15 | Polymerization of Butyl Methacrylate Catalyzed by Salicylaldehyde-Imine Zirconium/Al(i-Bu)_3 System显示文摘A new kind of zirconium(Zr) complex containing ligand of salicylaldehyde-imine was successfully synthesized with ZrCl_4·2 THF and salicylaldehyde-imine as raw materials. The ligand was characterized by means of ~1HNMR, IR, and GC-MS, and Zr complex was characterized by means of ~1HNMR and IR, respectively. The Zr complex, combined with co-catalyst of Al(i-Bu)_3, was explored to be effective catalytic system for the polymerization of butyl methacrylate(BMA), to prepare poly-n-butyl methacrylate(PBMA), which was characterized by IR, ~13C-NMR and GPC. Compared with other double-component(MAO/Cat, AlEt_3/Cat) catalytic systems, catalytic system of Al(i-Bu)_3 and the Zr complex provided the best catalytic activity under the same conditions. The influence of polymerization parameters, such as molar ratio of Al(i-Bu)_3/Cat and BMA/Cat, polymerization temperature and polymerization time, was studied with Zr complex/Al(i-Bu)_3 system. With increasing polymerization time from 4 to 24 hour, the monomer conversion increased from 40.14% to 96.56%. Viscosity-average molecular weight(M_v) of PBMA, detected by the viscosity methodology, increased from 12.67×10~4Da to 44.97×10~4Da and lower molecular weight distribution was obtained. According to these results, the Zr complex contained ligand of salicylaldehyde-imine was a kind of readily, long lifetime and high activity catalyst for BMA polymerization. | 程正载 TANG Ran 谢聪 WANG Yun DING Ling WANG Handing YAN Xiaochao ZHU Sanyong Gauthier Mario | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，2： | 0 |
