| 1 | Synthesis of rod-like metal-organic framework(MOF-5)nanomaterial for efficient removal of U(Ⅵ):batch experiments and spectroscopy study显示文摘With the widespread application of radionuclide235 U(Ⅵ), it is inevitable that part of U(Ⅵ) is released into the natural environment. The potential toxicity and irreversibility impact on the natural environment has become one of the most forefront pollution problems in nuclear energy utilization. In this work, rod-like metal-organic framework(MOF-5) nanomaterial was synthesized by a solvothermal method and applied to efficiently adsorb U(Ⅵ) from aqueous solutions. The batch experimental results showed that the sorption of U(Ⅵ) on MOF-5 was strongly dependent on p H and independent of ionic strength, indicating that the dominant interaction mechanism was inner-sphere surface complexation and electrostatic interaction. The maximum sorption capacity of U(Ⅵ) on MOF-5 was 237.0 mg/g at p H 5.0 and T = 298 K, and the sorption equilibrium reached within 5 min. The thermodynamic parameters indicated that the removal of U(Ⅵ) on MOF-5 was a spontaneous and endothermic process. Additionally, the FT-IR and XPS analyses implied that the high sorption capacity of U(Ⅵ) on MOF-5 was mainly attributed to the abundant oxygen-containing functional groups(i.e., CAO and C@O). Such a facile preparation method and efficient removal performance highlighted the application of MOF-5 as a candidate for rapid and efficient radionuclide contamination's elimination in practical applications. | Yihan Wu Hongwei Pang Wen Yao Xiangxue Wang Shujun Yu Zhimin Yu Xiangke Wang | 2018 | Science Bulletin2018，63，13： | 21 |
| 2 | In-situ reduction synthesis of manganese dioxide@polypyrrole core/shell nanomaterial for highly efficient enrichment of U(Ⅵ) and Eu(Ⅲ)显示文摘Radionuclides with long half-life are toxic,and thereby result in serious threat to human beings and ecological balance.Herein,a simple two-step synthesis method was used to prepare manganese dioxide@polypyrrole(Mn O_2@PPy)core/shell structures for efficient removal of U(Ⅵ)and Eu(Ⅲ)from aqueous solutions.The adsorption of U(Ⅵ)and Eu(Ⅲ)were investigated under different kinds of experimental conditions.The experimental results suggested that the adsorption of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy were greatly affected by p H.U(Ⅵ)adsorption on Mn O_2@PPy was independent of ionic strength at p H<6.0,and dependent on ionic strength at p H>6.0.However,Eu(Ⅲ)adsorption on Mn O_2@PPy was independent of ionic strength at the whole p H range of experimental conditions.The maximum adsorption capacities(q_(max))of U(Ⅵ)and Eu(Ⅲ)were 63.04 and54.74 mg g^(-1)at T=298 K,respectively.The BET,XRD,FTIR and XPS analysis evidenced that high adsorption capacities of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy were mainly due to high surface area and rich metal oxygen-containing group(i.e.,Mn–OH and Mn–O),and the interaction was mainly attributed to strong surface complexation and electrostatic interaction.This study highlighted the excellent adsorption performance of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy and could provide the reference for the elimination of radionuclides in real wastewater management. | Wen Yao Yihan Wu Hongwei Pang Xiangxue Wang Shujun Yu Xiangke Wang | 2018 | Science China Chemistry2018，61，7： | 7 |

| 4 | Identification of the Quaternary low gas-saturation reservoirs in the Sanhu area of the Qaidam Basin,China显示文摘低煤气浸透的水库是煤气的忍受其煤气的浸透是不到 47% 的间隔。他们是普通的在在 Qaidam 盆的 Sanhu 区域第四级。由于复杂开始机制和特殊地质的特征,低煤气浸透的水库的记载的曲线被歧义和差异描绘,也就是没有重要木头反应特征。因此,在学习区域识别低煤气浸透的水库是特别地困难的。另外,传统的方法象在岩性学,电的性质,忍受性质的物理性质和气体之中使用关系那样,以及他们的阀值价值,不能有效地识别低 gassaturation 水库。解决这个问题,我们采用决定树,支持向量机器和建立低煤气浸透的水库的一个预兆的模型的不平的集合方法,它能够分类多维、模糊的数据的一个团。根据学习过程和学习结果的可理解性的透明性,预兆的模型被吸收实际水库特征也修订。实际应用显示预兆的模型在在学习区域识别低煤气浸透的水库是有效的。 | Li Xiongyan Li Hongqi Zhou Jinyu He Xu Chen Yihan Yu Hongyan | 2011 | Petroleum Science2011，8，1： | 2 |
| 5 | Intergrowth mechanism and morphology prediction of faceted Al_(3)Ni formed during solidification by a spatial geometric model显示文摘The interplay and intergrowth characteristic of faceted intermetallic compounds(IMCs)during solidification was originally investigated through the rod-like Al3 Ni crystals in the liquid Al/solid Ni interconnection by using synchrotron radiography,and the diversified 3-D morphologies were reconstructed by synchrotron tomography.A spatial geometric model was established to effectively predict the diversified growth patterns of two spatial crystals.For the two overlapping Al3 Ni crystals,the impeded crystal growth was divided into three different stages,decided by the hindrance form the other crystal.Further,the groove formed on the crystal surface is directly related to the solute redistribution under the critical condition of boundary layer thickness larger than two crystals distance.The closer distance and smaller crystal size indicate the deeper and larger groove,and the morphology changes from hemispheroid to hemi-ellipsoid with the increased opposite and interacted faces. | Zongye Ding Qiaodan Hu Wenquan Lu Fan Yang Yihan Zhou Naifang Zhang Sheng Cao Liao Yu Jianguo Li | 2020 | Journal of Materials Science & Technology2020，54，19： | 2 |

| 7 | Mirror-enhanced scanning light-field microscopy for long-term high-speed 3D imaging with isotropic resolution显示文摘Various biological behaviors can only be observed in 3D at high speed over the long term with low phototoxicity.Light-field microscopy(LFM)provides an elegant compact solution to record 3D information in a tomographic manner simultaneously,which can facilitate high photon efficiency.However,LFM still suffers from the missing-cone problem,leading to degraded axial resolution and ringing effects after deconvolution.Here,we propose a mirrorenhanced scanning LFM(MiSLFM)to achieve long-term high-speed 3D imaging at super-resolved axial resolution with a single objective,by fully exploiting the extended depth of field of LFM with a tilted mirror placed below samples.To establish the unique capabilities of MiSLFM,we performed extensive experiments,we observed various organelle interactions and intercellular interactions in different types of photosensitive cells under extremely low light conditions.Moreover,we demonstrated that superior axial resolution facilitates more robust blood cell tracking in zebrafish larvae at high speed. | Bo Xiong Tianyi Zhu Yuhan Xiang Xiaopeng Li Jinqiang Yu Zheng Jiang Yihan Niu Dong Jiang Xu Zhang Lu Fang Jiamin Wu Qionghai Dai | 2021 | Light(Science & Applications)2021，10，12： | 1 |

| 10 | MOF-derived zinc manganese oxide nanosheets with valence-controllable composition for high-performance Li storage显示文摘Zinc manganese oxide(ZMO)system represents a notable family of mixed transition metal oxides(MTMOs)because of their superiority of the high theoretical capacity,adequacy of natural content,and low cost.However,the methods to match both the reliable synthesis and the designable construction of large-sized two-dimensional(2D)ZMO nanosheets are still considered as grand challenges.Herein,we have successfully realized the preparation of 2D ZMO nanosheets with large lateral sizes up to~20 mm by simple pyrolysis of 2D metal–organic framework(MOF)nanosheets precursor.The growth mechanism of 2D MOF is proposed to be based on the lamellar micelles formed by polyvinyl pyrrolidone(PVP).The obtained 2D and porous ZMO nanosheets exhibit high specific capacity as well as good rate capability.More importantly,the as-prepared ZMO electrode shows a remarkable capacity increment upon cycling(from 832 mAh g^(-1) at the 2nd cycle to 1418 mAh g^(-1) at the 700th cycle,at 1 A g^(-1)).Through simple adjustment of the calcination temperature,the valence state of Mn species in the yielding ZMO samples can be fine-tuned.Through systematic investigation towards these ZMOs containing different Mn species,the extra specific capacity is revealed to be chiefly on account of the arising of the valence state of Mn upon the cycling process.Moreover,it is disclosed that the higher-valent Mn the pristine ZMO contains,the more additional capacity it gains upon cycling.We believe that this work will inspire more detailed analysis on the relationship between the valence state of Mn and extra capacity. | Yu Du Yihan Xu Weiwei Zhou Yaoyang Yu Xinzhou Ma Fei Liu Jinglong Xu Yongming Zhu | 2021 | Green Energy & Environment2021，6，5： | 1 |
| 11 | Nonvolatile chirality switching in terahertz chalcogenide metasurfaces显示文摘Actively controlling the polarization states of terahertz(THz)waves is essential for polarization-sensitive spectroscopy,which has various applications in anisotropy imaging,noncontact Hall measurement,and vibrational circular dichroism.In the THz regime,the lack of a polarization modulator hinders the development of this spectroscopy.We theoretically and experimentally demonstrate that conjugated bilayer chiral metamaterials(CMMs)integrated with Ge_(2)Sb_(2)Te_(5)(GST225)active components can achieve nonvolatile and continuously tunable optical activity in the THz region.A THz time-domain spectroscopic system was used to characterize the device,showing a tunable ellipticity(from‒36°to 0°)and rotation of the plane polarization(from 32°to 0°)at approximately 0.73 THz by varying the GST225 state from amorphous(AM)to crystalline(CR).Moreover,a continuously tunable chiroptical response was experimentally observed by partially crystallizing the GST225,which can create intermediate states,having regions of both AM and CR states.Note that the GST225 has an advantage of nonvolatility over the other active elements and does not require any energy to retain its structural state.Our work allows the development of THz metadevices capable of actively manipulating the polarization of THz waves and may find applications for dynamically tunable THz circular polarizers and polarization modulators for THz emissions. | Jiaxin Bao Xieyu Chen Kuan Liu Yu Zhan Haiyang Li Shoujun Zhang Yihan Xu Zhen Tian Tun Cao | 2022 | Microsystems & Nanoengineering2022，8，5： | 0 |
| 12 | Three-dimensional-printed titanium prostheses with bone trabeculae enable mechanical-biological reconstruction after resection of bone tumours显示文摘Reconstruction after resection has always been an urgent problem in the treatment of bone tumours.There are many methods that can be used to reconstruct bone defects;however,there are also many complications,and it is difficult to develop a safe and effective reconstruction plan for the treatment of bone tumours.With the rapid development of digital orthopaedics,three-dimensional printing technology can solve this problem.The three-dimensional printing of personalised prostheses has many advantages.It can be used to print complex structures that are difficult to fabricate using traditional processes and overcome the problems of stress shielding and low biological activity of conventional prostheses.In this study,12 patients with bone tumours were selected as research subjects,and based on individualised reverse-engineering design technology,a three-dimensional model of each prosthesis was designed and installed using medical image data.Ti6Al4V was used as the raw material to prepare the prostheses,which were used to repair bone defects after surgical resection.The operation time was 266.43±21.08 minutes(range 180-390 minutes),and intraoperative blood loss was 857.26±84.28 mL(range 800-2500 mL).One patient had delayed wound healing after surgery,but all patients survived without local tumour recurrence,and no tumour metastasis was found.No aseptic loosening or structural fracture of the prosthesis,and no non-mechanical prosthesis failure caused by infection,tumour recurrence,or progression was observed.The Musculo-Skeletal Tumour Society(MSTS)score of limb function was 22.53±2.09(range 16-26),and ten of the 12 patients scored≥20 and were able to function normally.The results showed that three-dimensional printed prostheses with an individualised design can achieve satisfactory short-term clinical efficacy in the reconstruction of large bone defects after bone tumour resection. | Feifei Pu Wei Wu Doudou Jing Yihan Yu Yizhong Peng Jianxiang Liu Qiang Wu Baichuan Wang Zhicai Zhang Zengwu Shao | 2022 | Biomaterials Translational2022，3，2： | 0 |
| 13 | Towards overcoming obstacles of type Ⅱ photodynamic therapy:Endogenous production of light,photosensitizer,and oxygen显示文摘Conventional photodynamic therapy(PDT)approaches face challenges including limited light penetration,low uptake of photosensitizers by tumors,and lack of oxygen in tumor microenvironments.One promising solution is to internally generate light,photosensitizers,and oxygen.This can be accomplished through endogenous production,such as using bioluminescence as an endogenous light source,synthesizing genetically encodable photosensitizers in situ,and modifying cells genetically to express catalase enzymes.Furthermore,these strategies have been reinforced by the recent rapid advancements in synthetic biology.In this review,we summarize and discuss the approaches to overcome PDT obstacles by means of endogenous production of excitation light,photosensitizers,and oxygen.We envision that as synthetic biology advances,genetically engineered cells could act as precise and targeted“living factories”to produce PDT components,leading to enhanced performance of PDT. | Lin Yu Zhen Liu Wei Xu Kai Jin Jinliang Liu Xiaohui Zhu Yong Zhang Yihan Wu | 2024 | Acta Pharmaceutica Sinica B2024，14，3： | 0 |

| 15 | Adaptive Graph Convolutional Recurrent Neural Networks for System-Level Mobile Traffic Forecasting显示文摘Accurate traffic pattern prediction in largescale networks is of great importance for intelligent system management and automatic resource allocation.System-level mobile traffic forecasting has significant challenges due to the tremendous temporal and spatial dynamics introduced by diverse Internet user behaviors and frequent traffic migration.Spatialtemporal graph modeling is an efficient approach for analyzing the spatial relations and temporal trends of mobile traffic in a large system.Previous research may not reflect the optimal dependency by ignoring inter-base station dependency or pre-determining the explicit geological distance as the interrelationship of base stations.To overcome the limitations of graph structure,this study proposes an adaptive graph convolutional network(AGCN)that captures the latent spatial dependency by developing self-adaptive dependency matrices and acquires temporal dependency using recurrent neural networks.Evaluated on two mobile network datasets,the experimental results demonstrate that this method outperforms other baselines and reduces the mean absolute error by 3.7%and 5.6%compared to time-series based approaches. | Yi Zhang Min Zhang Yihan Gui Yu Wang Hong Zhu Wenbin Chen Danshi Wang | 2023 | China Communications2023，20，10： | 0 |
| 16 | The complexation of insulin with sodium N-[8-(2-hydroxybenzoyl)amino]-caprylate for enhanced oral delivery:Effects of concentration, ratio, and pH显示文摘Permeation enhancers(PEs),such as N-[8-(2-hydroxybenzoyl)amino]-caprylate(SNAC),have been reported to improve the oral absorption of various macromolecules.However,the bioavailabilities of these formulations are quite low and variable due to the influences of enzymes,pH and other gastrointestinal barriers.In this study,we revealed that SNAC could interact with insulin to form tight complexes in a specific concentration(insulin≥ 40μg/mL)-,ratio(SNAC/insulin≥ 20:1)-and pH(≥ 6.8)-dependent manner,thus contributing to a significantly high efficacy of oral insulin delivery.Specifically,absorption mechanism studies revealed that the SNAC/insulin complexes were internalized into the cells by passive diffusion and remained intact when transported in the cytosol.Furthermore,the complexes accelerated the exocytosis of insulin to the basolateral side,thereby enhancing its intestinal mucosal permeability.Eudragit;S100-entrapped SNAC/insulin microspheres were then prepared and exhibited an apparent permeability coefficient(P;) that was 6,6-fold higher than that of the insulin solution.In diabetic rats,hypoglycemic activity was sustained for more than 10 h after the microspheres were loaded into entericcoated capsules.Further pharmacokinetic studies revealed an approximately 6.3% oral bioavailability in both the fasted and fed states,indicating a negligible food effect.Collectively,this study provides insight into the interaction between PEs and payloads and presents an SNAC-based oral insulin delivery system that has high oral bioavailability and patient-friendly medication guidance. | Huixian Weng Lefei Hu Lei Hu Yihan Zhou Aohua Wang Ning Wang Wenzhe Li Chunliu Zhu Shiyan Guo Miaorong Yu Yong Gan | 2022 | Chinese Chemical Letters2022，33，4： | 0 |
| 17 | Development of a highly-specific ^(18)F-labeled irreversible positron emission tomography tracer for monoacylglycerol lipase mapping显示文摘As a serine hydrolase,monoacylglycerol lipase(MAGL) is principally responsible for the metabolism of 2-arachidonoylglycerol(2-AG) in the central nervous system(CNS),leading to the formation of arachidonic acid(AA).Dysfunction of MAGL has been associated with multiple CNS disorders and symptoms,including neuroinflammation,cognitive impairment,epileptogenesis,nociception and neurodegenerative diseases.Inhibition of MAGL provides a promising therapeutic direction for the treatment of these conditions,and a MAGL positron emission tomography(PET) probe would greatly facilitate preclinical and clinical development of MAGL inhibitors.Herein,we design and synthesize a small library of fluoropyridyl-containing MAGL inhibitor candidates.Pharmacological evaluation of these candidates by activity-based protein profiling identified 14 as a lead compound,which was then radiolabeled with fluorine-18 via a facile SNAr reaction to form 2-[^(18)F]fluoropyridine scaffold.Good blood-brain barrier permeability and high in vivo specific binding was demonstrated for radioligand [^(18)F]14(also named as [^(18)F]MAGL-1902).This work may serve as a roadmap for clinical translation and further design of potent 18F-labeled MAGL PET tracers. | Zhen Chen Wakana Mori Jian Rong Michael A.Schafroth Tuo Shao Richard S.Van Daisuke Ogasawara Tomoteru Yamasaki Atsuto Hiraishi Akiko Hatori Jiahui Chen Yiding Zhang Kuan Hu Masayuki Fujinaga Jiyun Sun Qingzhen Yu Thomas L.Collier Yihan Shao Benjamin F.Cravatt Lee Josephson Ming-Rong Zhang Steven H.Liang | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 0 |
| 18 | Preliminary Investigation of Preparing High Burn-Up Structure in Nuclear Fuel by Flash Sintering Using CeO_(2) as a Surrogate显示文摘The high burn-up structure(HBS)is characterized by the grain size of 100-300 nm and a porosity of up to 20%,which is formed at the rim of the nuclear fuel pellet due to 2-3 times higher local burn-up during the in-pile irradiation.HBS is considered a new potential structure for high-performance fuels.However,it is difficult to prepare HBS by conventional sintering methods.In this study,flash sintering was used to prepare HBS using CeO_(2)as a surrogate for a preliminary investigation.A new experimental configuration for rapid sintering of CeO_(2)pellets was provided,in which the green body can be rapidly preheated and pressure-assisted by the induction heating electrodes.An insulated quartz tube was used as the die for the flash sintered samples,allowing the current to flow through the sample and providing a stable condition for applying an external pressure of approximately 5.3-7.0 MPa during flash sintering process.Using an initial electric field of 141 V cm-1 and holding for 1-7 min at the maximum current density of~98 mA mm^(-2),CeO_(2)ceramics with a grain size of 114-282 nm and a relative density of 75.4-99.7%were prepared.The densification and microstructure evolution behaviors during flash sintering in this new experimental configuration have been discussed in detail.This new experimental configuration may provide a promising approach for preparing UO_(2)ceramics and their HBS. | Tongye Li Jing Yang Chong Yu Yihan Liang Yang Li Xinfang Zhang | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，12： | 0 |
| 19 | A low-carbon economic dispatch model for electricity market with wind power based on improved ant-lion optimisation algorithm显示文摘Introducing carbon trading into electricity market can convert carbon dioxide into schedulable resources with economic value.However,the randomness of wind power generation puts forward higher requirements for electricity market transactions.Therefore,the carbon trading market is introduced into the wind power market,and a new form of low-carbon economic dispatch model is developed.First,the economic dispatch goal of wind power is be considered.It is projected to save money and reduce the cost of power generation for the system.The model includes risk operating costs to account for the impact of wind power output variability on the system,as well as wind farm negative efficiency operating costs to account for the loss caused by wind abandonment.The model also employs carbon trading market metrics to achieve the goal of lowering system carbon emissions,and analyze the impact of different carbon trading prices on the system.A low-carbon economic dispatch model for the wind power market is implemented based on the following two goals.Finally,the solution is optimised using the Ant-lion optimisation method,which combines Levi's flight mechanism and golden sine.The proposed model and algorithm's rationality is proven through the use of cases. | Renwu Yan Yihan Lin Ning Yu Yi Wu | 2023 | CAAI Transactions on Intelligence Technology2023，8，1： | 0 |
