| 1 | Surface curvature-confined strategy to ultrasmall nickel-molybdenum sulfide nanoflakes for highly efficient deep hydrodesulfurization显示文摘Size-controlled synthesis of two-dimensional(2D)catalysts with low stacking numbers and small nanoflake lengths is crucial for promoting the catalytic performance in diverse heterogeneous catalysis.Herein,we report a facile and general“surface curvature-confined synthesis”strategy to modulate the slab lengths and stacking numbers of 2D transition metal sulfides by controlling the strain induced by different surface curvature of supports.An efficient NiMo sulfide with shorter slab length(average 3.71 nm),less stacking number(1–2 layers)and more edge active sites is synthesized onto ZSM-5 zeolites with the average size of 100 nm,which shows superior kHDS value of dibenzothiophene(14.05×10^−7 mol/(g·s)),enhanced stability up to 80 h,and high direct desulfurization selectivity(>95%).This design concept is also proved to be generally applicable to modulate the slab lengths and stacking numbers of other 2D catalysts such as MoS2 and WS2 nanoflakes,which shows great potentials for developing more ultrasmall 2D catalysts with controlled sizes and excellent catalytic activities. | Xin Kang Jiancong Liu Chungui Tian Dongxu Wang Yaorui Li Hongyan Zhang Xusheng Cheng Aiping Wu Honggang Fu | 2020 | Nano Research2020,13,3: | 5 |
| 2 | The confined growth of few-layered and ultrashort-slab Ni-promoted MoS_(2)on reduced graphene oxide for deep-degree hydrodesulfurization显示文摘Hydrodesulfurization(HDS)is an essential process in clean fuel oil production,however,the huge challenge is the synthesis of the catalyst with plentiful active sites.Here,we have shown the design of few-layered,ultrashort Ni-Mo-S slabs dispersed on reduced graphene oxide(Ni-Mo-S/rGO-A)based on anchoring[PMo_(12)O_(40)]3−clusters and Ni^(2+)on polyethyleneimine(PEI)-modified graphite oxide.Structural characterizations(transmission electron microscopy(TEM),X-ray absorption fine structure(XAFS),etc.)show that Ni-Mo-S slabs with predominant monolayer and partial substitution of edge Mo atoms by isolated Ni atoms have rich accessible edge Ni-Mo-S sites and high sulfurization degree.All virtues endow it with plentiful edge-active sites,and consequently,the enhanced performance for hydrodesulfurization of dibenzothiophene(DBT).The hydrodesulfurization proceeds via a more-favorable direct desulfurization(DDS)route with a reaction rate constant(kHDS)of 48.6×10^(−7)mol·g^(−1)·s^(−1)over Ni-Mo-S/rGO-A catalyst,which is 4.3 times greater than that over traditional Ni-Mo-S/Al_(2)O_(3)catalyst and at the forefront of reported catalysts. | Dongxu Wang Lei Wang Yanqing Jiao Aiping Wu Haijing Yan Xin Kang Chungui Tian Jiancong Liu Honggang Fu | 2022 | Nano Research2022,15,8: | 2 |

| 5 | Carbon Dots-in-Zeolite via In-Situ Solvent-Free Thermal Crystallization:Achieving High-Efficiency and Ultralong Afterglow Dual Emission显示文摘Organic afterglow materials are highly desirable for optoelectronic applications,but they usually suffer from complex preparation process,low quantum efficiency,and short lifetime due to the ultrafast deactivation of the highly active excited states involved.Here,we succeeded in achieving solventfree thermal syntheses of high-efficiency afterglow CDs@zeolite composite materials by simply grinding the solid raw materials of zeolite and precursor CDs at room temperature,followed by thermal crystallization.This method afforded maximum embedding of CDs into growing zeolite crystals,as well as strong host–guest interaction to surpass the nonradiative transition of CDs,thus producing composite materials with ultralong dual emission of thermally activated delayed fluorescence and room temperature phosphorescence with a record high lifetime of 1.7 and 2.1 s,respectively,and the quantum yield of 90.7%.Furthermore,in a preliminary experiment,we applied the composite materials in alternatingcurrent light-emitting diode supplementary lighting,which exhibited a promising potential in optoelectronic applications. | Hongyue Zhang Kaikai Liu Jiancong Liu Bolun Wang Chengyu Li Wei Song Jiyang Li Ling Huang Jihong Yu | 2020 | CCS Chemistry2020,2,3: | 1 |
| 6 | 术前低蛋白血症会增加克罗恩病一期肠吻合术后腹腔内感染性并发症的发生风险显示文摘目的:本研究旨在探讨术前低蛋白血症对克罗恩病(CD)患者一期肠吻合术后发生腹腔内感染性并发症(IASCs)的影响。方法:2007-2015年期间所有行肠切除一期肠吻合手术的CD患者纳入研究。采用单因素和多因素分析评估术前低蛋白血症(白蛋白<30 g/L)与术后IASCs发生风险的关系。结果:共计124例患者纳入研究,其中117例(94.4%)可以获得术前白蛋白水平的数据。13例(11.7%)患者术前合并低蛋白血症。相较之下,术前低蛋白血症患者CD诊断至手术的间期更长(P=0.012),术前服用5氨基水杨酸的比例更高(P=0.013),术中发现小肠梗阻的比例更高(P=0.015)。共有24例(19.4%)患者术后出现IASCs。单因素分析显示,术前低蛋白血症患者术后IASCs风险更高(P=0.012)。多因素分析证实,术前低蛋白血症是术后IASCs的独立危险因素(OR=4.67,95%CI:1.28–17.04,P=0.02)。将术前白蛋白水平作为一个连续型变量进行多因素分析,亦可得到相同的结果(P=0.019)。结论:对于行肠切除一期肠吻合的CD患者,术前低蛋白血症提示术后IASCs发生风险增高。改善术前营养状态或可降低术后IASCs的发生风险。 | Xuanhui Liu Xianrui Wu Chi Zhou Tuo Hu Jia Ke Yufeng Chen Xiaosheng He Xiaobin Zheng Xiaowen He Jiancong Hu Min Zhi Xiang Gao Pinjin Hu Xiaojian Wu Ping Lan | 2017 | Gastroenterology Report2017,5,4: | 1 |

| 10 | Incidence and risk factors for incisional surgical site infection in patients with Crohn’s disease undergoing bowel resection显示文摘Background:Patients with Crohn’s disease(CD)are often reported to be at a high risk for incisional surgical site infection(SSI).The aim of this study was to identify the risk factors associated with post-operative incisional SSI in CD patients after bowel resection.Method:CD patients undergoing bowel resection between 2007 and 2015 were enrolled.Demographic and clinical features related to post-operative incisional SSI were analysed using both univariate and multivariate logistical analyses.Results:Of all eligible patients(n=159),123(77.4%)were male,with a mean age at surgery of 33.4611.8 years.A total of 35(22.0%)CD patients developed post-operative incisional SSI.Post-operative incisional SSI was more likely to happen in patients who had penetrating type of disease(P=0.018),underwent bowel resection for the indication of chronic fistula(P=0.005)and had an intra-operative finding of fistula(P=0.001).A greater proportion of patients with post-operative incisional SSI were found to have anemia(P=0.019)but elevated levels of white blood cells(P=0.027),neutrophils(P=0.006)as well as an elevated percentage of neutrophils(P=0.005).Multivariate logistic regression analysis showed that anemia(odds ratio[OR]:3.31,95%confidence interval[CI]:1.05-10.46,P=0.041),an elevated percentage of neutrophils(OR:2.85,95%CI:1.23-6.59,P=0.014)and an intra-operative finding of fistula(OR:3.76,95%CI:1.53-9.21,P=0.004)were significantly associated with the risk for post-operative incisional SSI.Conclusions:Anemia,elevated percentage of neutrophils and intra-operative finding of fistula are predictors for the development of post-operative incisional SSI in CD patients undergoing bowel resection.Favorable pre-operative nutrition status and low inflammatory status may lessen the incidence of post-operative incisional SSI. | Tuo Hu Xianrui Wu Jiancong Hu Yufeng Chen Huashan Liu Chi Zhou Xiaowen He Min Zhi Xiaojian Wu Ping Lan | 2018 | Gastroenterology Report2018,6,3: | 0 |
| 11 | Toward memristive in-memory computing:principles and applications显示文摘With the rapid growth of computer science and big data,the traditional von Neumann architecture suffers the aggravating data communication costs due to the separated structure of the processing units and memories.Memristive in-memory computing paradigm is considered as a prominent candidate to address these issues,and plentiful applications have been demonstrated and verified.These applications can be broadly categorized into two major types:soft computing that can tolerant uncertain and imprecise results,and hard computing that emphasizes explicit and precise numerical results for each task,leading to different requirements on the computational accuracies and the corresponding hardware solutions.In this review,we conduct a thorough survey of the recent advances of memristive in-memory computing applications,both on the soft computing type that focuses on artificial neural networks and other machine learning algorithms,and the hard computing type that includes scientific computing and digital image processing.At the end of the review,we discuss the remaining challenges and future opportunities of memristive in-memory computing in the incoming Artificial Intelligence of Things era. | Han Bao Houji Zhou Jiancong Li Huaizhi Pei Jing Tian Ling Yang Shengguang Ren Shaoqin Tong Yi Li Yuhui He Jia Chen Yimao Cai Huaqiang Wu Qi Liu Qing Wan Xiangshui Miao | 2022 | Frontiers of Optoelectronics2022,15,2: | 0 |
