| 1 | Effect of composite supports on the methanation activity of Co-Mo-based sulphur-resistant catalysts显示文摘The effects of composite supports of CeO2-Al2O3,MgO-Al2O3,TiO2-Al2O3 or ZrO2-Al2O3 on the methanation activity of supported Co-Mo-based sulphur-resistant catalysts were investigated.The catalysts were further characterized by nitrogen adsorption measurement,X-ray diffraction and X-ray photoelectron spectroscopy.The catalyst of 5%CoO-15%MoO3 supported on CeO2-Al2O3,MgO-Al2O3,TiO2-Al2O3 or ZrO2-Al2O3 composite oxides,respectively,showed different catalytic performances of syngas methanation in the presence of hydrogen sulphide as compared with that of the 5%CoO-15%MoO3/Al2O3 catalyst.The Co-Mo/CeO2-Al2O3 catalyst shows the highest methanation activity among the tested catalysts.The enhanced methanation activity may be attributed to the improvement of the dispersion of active metal species and the inhibition of the formation of S6+. | Haiyang Wang Zhenhua Li Erdong Wang Can Lin Yuguang Shang Guozhong Ding Xinbin Ma Shaodong Qin Qi Sun | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 15 |
| 2 | Three-Dimensional Self-assembled Hairball-Like VS4 as High-Capacity Anodes for Sodium-Ion Batteries显示文摘Sodium-ion batteries(SIBs)are considered to be attractive candidates for large-scale energy storage systems because of their rich earth abundance and consistent performance.However,there are still challenges in developing desirable anode materials that can accommodate rapid and stable insertion/extraction of Na+and can exhibit excellent electrochemical performance.Herein,the self-assembled hairball-like VS4 as anodes of SIBs exhibits high discharge capacity(660 and 589 mAh g−1 at 1 and 3 A g−1,respectively)and excellent rate property(about 100%retention at 10 and 20 A g−1 after 1000 cycles)at room temperature.Moreover,the VS4 can also exhibit 591 mAh g−1 at 1 A g−1 after 600 cycles at 0°C.An unlike traditional mechanism of VS4 for Na+storage was proposed according to the dates of ex situ characterization,cyclic voltammetry,and electrochemical kinetic analysis.The capacities of the final stabilization stage are provided by the reactions of reversible transformation between Na2S and S,which were considered the reaction mechanisms of Na–S batteries.This work can provide a basis for the synthesis and application of sulfur-rich compounds in fields of batteries,semiconductor devices,and catalysts. | Shuangshuang Ding Bingxin Zhou Changmiao Chen Zhao Huang Pengchao Li Shuangyin Wang Guozhong Cao Ming Zhang | 2020 | Nano-Micro Letters2020，12，3： | 3 |
| 3 | Injectable silk/hydroxyapatite nanocomposite hydrogels with vascularization capacity for bone regeneration显示文摘Localized and sustained osteogenic-angiogenic stimulation to bone defects is critical for effective bone repair.Here,desferrioxamine(DFO)was loaded on silk fibroin nanofibers and blended with hydroxyapatite nanorods(HA),forming injectable DFO-loaded silk fibroin-HA nanocomposite hydrogels.The composite hydrogels remained homogeneous distribution of HA with high ratio(60%)and also higher stiffness than that of pure silk fibroin nanofiber hydrogels,which provided stable osteogenic stimulation niches for tissue regeneration.Without the scarify of injectability,the hydrogels achieved slow delivery of DFO for above 60 days,resulting in suitable angiogenesis in vitro and in vivo and better osteogenesis than DFO-free systems.Compared to previous injectable silk fibroin-HA hydrogels,the introduction of vascularization capacity further stimulated the osteogenic differentiation of stem cells and accelerated new bone formation.Quicker and better bone healing were detected at defect sites after the injection of DFO-loaded nanocomposite hydrogels,indicating the effective synergistic effect of osteogenic and angiogenic cues.This work provides a simple and effective strategy of introducing angiogenic cues to bone matrices.We believe that the injectable nanocomposite hydrogels are suitable for the regeneration of bone tissues. | Keke Wang Weinan Cheng Zhaozhao Ding Gang Xu Xin Zheng Meirong Li Guozhong Lu Qiang Lu | 2021 | Journal of Materials Science & Technology2021，，4： | 2 |

| 6 | Electric field-driven building blocks for introducing multiple gradients to hydrogels显示文摘Gradient biomaterials are considered as preferable matrices for tissue engineering due to better simulation of native tissues.The introduction of gradient cues usually needs special equipment and complex process but is only effective to limited biomaterials.Incorporation of multiple gradients in the hydrogels remains challenges.Here,betasheet rich silk nanofibers(BSNF)were used as building blocks to introduce multiple gradients into different hydrogel systems through the joint action of crosslinking and electric field.The blocks migrated to the anode along the electric field and gradually stagnated due to the solution-hydrogel transition of the systems,finally achieving gradient distribution of the blocks in the formed hydrogels.The gradient distribution of the blocks could be tuned easily through changing different factors such as solution viscosity,which resulted in highly tunable gradient of mechanical cues.The blocks were also aligned under the electric field,endowing orientation gradient simultaneously.Different cargos could be loaded on the blocks and form gradient cues through the same crosslinking-electric field strategy.The building blocks could be introduced to various hydrogels such as Gelatin and NIPAM,indicating the universality.Complex niches with multiple gradient cues could be achieved through the strategy.Silk-based hydrogels with suitable mechanical gradients were fabricated to control the osteogenesis and chondrogenesis.Chondrogenic-osteogenic gradient transition was obtained,which stimulated the ectopic osteochondral tissue regeneration in vivo.The versatility and highly controllability of the strategy as well as multifunction of the building blocks reveal the applicability in complex tissue engineering and various interfacial tissues. | Gang Xu Zhaozhao Ding Qiang Lu Xiaoyi Zhang Xiaozhong Zhou Liying Xiao Guozhong Lu David L K aplan | 2020 | Protein & Cell2020，11，4： | 0 |
