| 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 | Classification of brain arteriovenous malformations located in motor-related areas based on location and anterior choroidal artery feeding显示文摘Objective Surgical management of arteriovenous malformations(AVMs)involving motor cortex or fibre tracts(M-AVMs)is challenging.This study aimed to construct a classification system based on nidus locations and anterior choroidal artery(AChA)feeding to pre-surgically evaluate motor-related and seizure-related outcomes in patients undergoing resection of M-AVMs.Methods and materials A total of 125 patients who underwent microsurgical resection of M-AVMs were retrospectively reviewed.Four subtypes were identified based on nidus location:(I)nidus involving the premotor area and/or supplementary motor areas;(II)nidus involving the precentral gyrus;(III)nidus involving the corticospinal tract(CST)and superior to the posterior limb of the internal capsule;(IV)nidus involving the CST at or inferior to the level of posterior limb of the internal capsule.In addition,we divided type IV into type IVa and type IVb according to the AChA feeding.Surgical-related motor deficit(MD)evaluations were performed 1 week(short-term)and 6 months(long-term)after surgery.Results The type I patients exhibited the highest incidence(62.0%)of pre-surgical epilepsy among the four subtypes.Multivariate analysis showed that motor-related area subtypes(p=0.004)and diffuse nidus(p=0.014)were significantly associated with long-term MDs.Long-term MDs were significantly less frequent in type I than in the other types.Type IV patients acquired the highest proportion(four patients,25.0%)of long-term poor outcomes(mRS>2).Type IVb patients showed a significantly higher incidence of post-surgical MDs than type IVa patients(p=0.041).The MDs of type III or IV patients required more recovery time.Of the 62 patients who had pre-surgical seizures,90.3%(56/62)controlled their seizures well and reached Engel class I after surgery.Conclusions Combining the consideration of location and AChA feeding,the classification for M-AVMs is a useful approach for predicting post-surgical motor function and decision-making. | Yuming Jiao Hao Li Weilun Fu Jiancong Weng Ran Huo Yinyan Wang Shuo Wang Tao Jiang Yong Cao Ji Zong Zhao | 2021 | Stroke & Vascular Neurology2021，6，3： | 4 |
| 3 | Multiply accumulate operations in memristor crossbar arrays for analog computing显示文摘Memristors are now becoming a prominent candidate to serve as the building blocks of non-von Neumann inmemory computing architectures.By mapping analog numerical matrices into memristor crossbar arrays,efficient multiply accumulate operations can be performed in a massively parallel fashion using the physics mechanisms of Ohm’s law and Kirchhoff’s law.In this brief review,we present the recent progress in two niche applications:neural network accelerators and numerical computing units,mainly focusing on the advances in hardware demonstrations.The former one is regarded as soft computing since it can tolerant some degree of the device and array imperfections.The acceleration of multiple layer perceptrons,convolutional neural networks,generative adversarial networks,and long short-term memory neural networks are described.The latter one is hard computing because the solving of numerical problems requires high-precision devices.Several breakthroughs in memristive equation solvers with improved computation accuracies are highlighted.Besides,other nonvolatile devices with the capability of analog computing are also briefly introduced.Finally,we conclude the review with discussions on the challenges and opportunities for future research toward realizing memristive analog computing machines. | Jia Chen Jiancong Li Yi Li Xiangshui Miao | 2021 | Journal of Semiconductors2021，42，1： | 2 |
| 4 | 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 |

| 11 | 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 |

| 13 | Method for designing organization decision support system framework显示文摘The concept of organization decision support system (ODSS) is defined according to practical applications and novel understanding. And a framework for ODSS is designed. The framework has three components: infrastructure, decision-making process and decision execution process. Infrastructure is responsible to transfer data and information. Decision-making process is the ODSS’s soul to support decision-making. Decision execution process is to evaluate and execute decision results derived from decision-making process. The framework presents a kind of logic architecture. An example is given to verify and analyze the framework. The analysis shows that the framework has practical values, and has also reference values for understanding ODSS and for theoretical studies. | Fan Jiancong Liang Yongquan Zeng Qingtian | 2006 | Journal of Systems Engineering and Electronics2006，17，4： | 1 |
| 14 | 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 |

| 20 | Risk factors for recurrence of colorectal conventional adenoma and serrated polyp显示文摘Background Removal of colorectal polyps during screening could reduce the incidence of colorectal cancer(CRC).However,there is a lack of data on risk factors associated with recurrence of polyps,including conventional adenomas and serrated polyps(SPs).This study aimed to determine risk factors for recurrence of colorectal polyps and their subtypes based on the characteristics of the patients and polyps.Methods A total of 1,165 patients diagnosed with conventional adenoma or SP in the Sixth Affiliated Hospital of Sun Yat-sen University between January 2013 and December 2019 were enrolled in this study,including 668 cases with conventional adenomas,385 with SPs,and 112 with coexistence of adenomas and SPs.Univariate analysis and multivariate logistic regression were used to identify potential risk factors for polyp recurrence.A nomogram was established according to risk factors and the performance was evaluated using calibration plots.Results During a median follow-up of 24 months,recurrent polyps were observed in 531(45.6%)cases.Male,age≥50 years,body mass index(BMI)≥24 kg/m^(2),at least three polyps,smoking,alcohol consumption,family history of polyps,and family history of CRC were independent risk factors for polyp recurrence.The Harrell’s C-index of the nomogram developed with these parameters was 0.69 and the calibration plots showed good agreement between actual polyp recurrence and nomogram-predicted recurrence probability.In the subtype analyses,conventional adenomas had the same risk factors for recurrence as all polyps,while smoking,alcohol consumption,family history of polyps,and family history of CRC were not risk factors for SP recurrence.Conclusions We identified several risk factors for recurrence of colorectal polyps and found that some of them could increase the risk of adenoma recurrence but not SP recurrence,including smoking,alcohol consumption,and family history of polyps/CRC,which might help us to understand different etiology and biology between conventional adenomas and SPs. | Zengjie Chi Yanyun Lin Juanni Huang Min-Yi Lv Junguo Chen Xijie Chen Bin Zhang Yufeng Chen Jiancong Hu Xiaosheng He Ping Lan | 2022 | Gastroenterology Report2022，10，1： | 1 |
