| 1 | High-security-level multi-dimensional optical storage medium:nanostructured glass embedded with LiGa_(5)O_(8):Mn^(2+) with photostimulated luminescence显示文摘The launch of the big data era puts forward challenges for information preservation technology,both in storage capacity and security.Herein,a brand new optical storage medium,transparent glass ceramic(TGC)embedded with photostimulated LiGa5O8:Mn2+nanocrystals,capable of achieving bit-by-bit optical data write-in and read-out in a photon trapping/detrapping mode,is developed.The highly ordered nanostructure enables light–matter interaction with high encoding/decoding resolution and low bit error rate.Importantly,going beyond traditional 2D optical storage,the high transparency of the studied bulk medium makes 3D volumetric optical data storage(ODS)possible,which brings about the merits of expanded storage capacity and improved information security.Demonstration application confirmed the erasable-rewritable 3D storage of binary data and display items in TGC with intensity/wavelength multiplexing.The present work highlights a great leap in photostimulated material for ODS application and hopefully stimulates the development of new multi-dimensional ODS media. | Shisheng Lin Hang Lin Chonggeng Ma Yao Cheng Sizhe Ye Fulin Lin Renfu Li Ju Xu Yuansheng Wang | 2020 | Light(Science & Applications)2020，9，1： | 12 |
| 2 | Aircraft engine fault detection based on grouped convolutional denoising autoencoders显示文摘Many existing aircraft engine fault detection methods are highly dependent on performance deviation data that are provided by the original equipment manufacturer. To improve the independent engine fault detection ability, Aircraft Communications Addressing and Reporting System(ACARS) data can be used. However, owing to the characteristics of high dimension, complex correlations between parameters, and large noise content, it is difficult for existing methods to detect faults effectively by using ACARS data. To solve this problem, a novel engine fault detection method based on original ACARS data is proposed. First, inspired by computer vision methods, all variables were divided into separated groups according to their correlations. Then, an improved convolutional denoising autoencoder was used to extract the features of each group. Finally, all of the extracted features were fused to form feature vectors. Thereby, fault samples could be identified based on these feature vectors. Experiments were conducted to validate the effectiveness and efficiency of our method and other competing methods by considering real ACARS data as the data source. The results reveal the good performance of our method with regard to comprehensive fault detection and robustness. Additionally, the computational and time costs of our method are shown to be relatively low. | Xuyun FU Hui LUO Shisheng ZHONG Lin LIN | 2019 | Chinese Journal of Aeronautics2019，32，2： | 6 |
| 3 | Tunable Dynamic Black Phosphorus/Insulator/Si Heterojunction Direct-Current Generator Based on the Hot Electron Transport显示文摘Static heterojunction-based electronic devices have been widely applied because carrier dynamic processes between semiconductors can be designed through band gap engineering.Herein,we demonstrate a tunable direct-current generator based on the dynamic heterojunction,whose mechanism is based on breaking the symmetry of drift and diffusion currents and rebounding hot carrier transport in dynamic heterojunctions.Furthermore,the output voltage can be delicately adjusted and enhanced with the interface energy level engineering of inserting dielectric layers.Under the ultrahigh interface electric field,hot electrons will still transfer across the interface through the tunneling and hopping effect.In particular,the intrinsic anisotropy of black phosphorus arising from the lattice structure produces extraordinary electronic,transport,and mechanical properties exploited in our dynamic heterojunction generator.Herein,the voltage of 6.1 V,current density of 124.0 A/m^(2),power density of 201.0 W/m^(2),and energy-conversion efficiency of 31.4%have been achieved based on the dynamic black phosphorus/AlN/Si heterojunction,which can be used to directly and synchronously light up light-emitting diodes.This direct-current generator has the potential to convert ubiquitous mechanical energy into electric energy and is a promising candidate for novel portable and miniaturized power sources in the in situ energy acquisition field. | Yanghua Lu Sirui Feng Runjiang Shen Yujun Xu Zhenzhen Hao Yanfei Yan Haonan Zheng Xutao Yu Qiuyue Gao Panpan Zhang Shisheng Lin | 2019 | Research2019，，1： | 2 |
| 4 | Interfacial Built-In Electric Field-Driven Direct Current Generator Based on Dynamic Silicon Homojunction显示文摘Searching for light and miniaturized functional device structures for sustainable energy gathering from the environment is the focus of energy society with the development of the internet of things.The proposal of a dynamic heterojunction-based direct current generator builds up new platforms for developing in situ energy.However,the requirement of different semiconductors in dynamic heterojunction is too complex to wide applications,generating energy loss for crystal structure mismatch.Herein,dynamic homojunction generators are explored,with the same semiconductor and majority carrier type.Systematic experiments reveal that the majority of carrier directional separation originates from the breaking symmetry between carrier distribution,leading to the rebounding effect of carriers by the interfacial electric field.Strikingly,NN Si homojunction with different Fermi levels can also output the electricity with higher current density than PP/PN homojunction,attributing to higher carrier mobility.The current density is as high as 214.0 A/m^(2),and internal impedance is as low as 3.6 kΩ,matching well with the impedance of electron components.Furthermore,the N-i-N structure is explored,whose output voltage can be further improved to 1.3V in the case of the N-Si/Al2O3/N-Si structure,attributing to the enhanced interfacial barrier.This approach provides a simple and feasible way of converting low-frequency disordered mechanical motion into electricity. | Yanghua Lu Qiuyue Gao Xutao Yu Haonan Zheng Runjiang Shen Zhenzhen Hao Yanfei Yan Panpan Zhang Yu Wen Guiting Yang Shisheng Lin | 2020 | Research2020，，1： | 2 |
| 5 | A step parameters prediction model based on transfer process neural network for exhaust gas temperature estimation after washing aero-engines显示文摘The prediction of Exhaust Gas Temperature Margin(EGTM)after washing aeroengines can provide a theoretical basis for airlines not only to evaluate the energy-saving effect and emission reduction,but also to formulate reasonable maintenance plans.However,the EGTM encounters step changes after washing aeroengines,while,in the traditional models,a persistence tendency exists between the prediction results and the previous data,resulting in low accuracy in prediction.In order to solve the problem,this paper develops a step parameters prediction model based on Transfer Process Neural Networks(TPNN).Especially,“step parameters”represent the parameters that can reflect EGTM step changes.They are analyzed in this study,and thus the model concentrates on the prediction of step changes rather than the extension of data trends.Transfer learning is used to handle the problem that few cleaning records result in few step changes for model learning.In comparison with Long Short-Term Memory(LSTM)and Kernel Extreme Learning Machine(KELM)models,the effectiveness of the proposed method is verified on CFM56-5B engine data. | Zhiqi YAN Shisheng ZHONG Lin LIN Zhiquan CUI Minghang ZHAO | 2022 | Chinese Journal of Aeronautics2022，35，3： | 1 |

| 7 | Wavelength-Dependent Solar N_(2) Fixation into Ammonia and Nitrate in Pure Water显示文摘Solar-driven N_(2) fixation using a photocatalyst in water presents a promising alternative to the traditional Haber-Bosch process in terms of both energy efficiency and environmental concern.At present,the product of solar N_(2) fixation is either NH_(4)^(+)or NO_(3)^(-).Few reports described the simultaneous formation of ammonia(NH_(4)^(+))and nitrate(NO_(3)^(-))by a photocatalytic reaction and the related mechanism.In this work,we report a strategy to photocatalytically fix nitrogen through simultaneous reduction and oxidation to produce NH_(4)^(+)and NO_(3)^(-)byW18O49 nanowires in pure water.The underlying mechanism of wavelength-dependent N_(2) fixation in the presence of surface defects is proposed,with an emphasis on oxygen vacancies that not only facilitate the activation and dissociation of N_(2) but also improve light absorption and the separation of the photoexcited carriers.Both NH_(4)^(+)and NO_(3)^(-)can be produced in pure water under a simulated solar light and even till the wavelength reaching 730 nm.The maximum quantum efficiency reaches 9%at 365 nm.Theoretical calculation reveals that disproportionation reaction of the N_(2) molecule is more energetically favorable than either reduction or oxidation alone.It is worth noting that the molar fraction of NH_(4)^(+)in the total product(NH_(4)^(+)plus NO_(3)^(-))shows an inverted volcano shape from 365nm to 730 nm.The increased fraction of NO_(3)^(-)from 365 nm to around 427 nm results from the competition between the oxygen evolution reaction(OER)at W sites without oxygen vacancies and the N_(2) oxidation reaction(NOR)at oxygen vacancy sites,which is driven by the intrinsically delocalized photoexcited holes.From 427nm to 730 nm,NOR is energetically restricted due to its higher equilibrium potential than that of OER,accompanied by the localized photoexcited holes on oxygen vacancies.Full disproportionation of N_(2) is achieved within a range of wavelength from~427nm to~515 nm.This work presents a rational strategy to efficiently utilize the photoexcited carriers and optimize the photocatalyst for practical nitrogen fixation. | Wenju Ren Zongwei Mei Shisheng Zheng Shunning Li Yuanmin Zhu Jiaxin Zheng Yuan Lin Haibiao Chen Meng Gu Feng Pan | 2020 | Research2020，，1： | 1 |

| 9 | Graphene/Semiconductor Heterostructure Wireless Energy Harvester through Hot Electron Excitation显示文摘Recharging the batteries by wireless energy facilitates the long-term running of the batteries,which will save numerous works of battery maintenance and replacement.Thus,harvesting energy form radio frequency(RF)waves has become the most promising solution for providing the micropower needed for wireless sensor applications,especially in a widely distributed 4G/5G wireless network.However,the current research on rectenna is mainly focused on the integrated antenna coupled with metal-insulator-metal tunneling diodes.Herein,by adopting the plasmon excitation of graphene and quantum tunneling process between graphene and GaAs or GaN,we demonstrated the feasibility of harvesting energy from the 915MHz wireless source belonging to 5G in the FR1 range(450MHz-6 GHz)which is also known as sub-6G.The generated current and voltage can be observed continuously,with the direction defined by the built-in field between graphene and GaAs and the incident electromagnetic waves treated as the quantum energy source.Under the RF illumination,the generated current increases rapidly and the value can reach in the order of 10^(-8)-10^(-7)A.The harvester can work under the multiple channel mode,harvesting energy simultaneously from different flows of wireless energy in the air.This research will open a new avenue for wireless harvesting by using the ultrafast process of quantum tunneling and unique physical properties of graphene. | Yangfan Xuan Hong Chen Yan Chen Haonan Zheng Yanghua Lu Shisheng Lin | 2020 | Research2020，，1： | 1 |

| 11 | Ab initio electronic transport study of two-dimensional silicon carbide-based p–n junctions显示文摘Two-dimensional silicon carbide(2d-SiC) is a viable material for next generation electronics due to its moderate,direct bandgap with huge potential.In particular,its potential for p–n junctions is yet to be explored.In this paper,three types of 2d-SiC-based p–n junctions with different doping configuration are modeled.The doping configurations refer to partially replacing carbon with boron or nitrogen atoms along the zigzag or armchair direction,respectively.By employing density functional theory,we calculate the transport properties of the SiC based p–n junctions and obtain negative differential resistance and high rectification ratio.We also find that the junction along the zigzag direction with lower doping density exhibits optimized rectification performance.Our study suggests that 2d-SiC is a promising candidate as a material platform for future nano-devices. | Hanming Zhou Xiao Lin Hongwei Guo Shisheng Lin Yiwei Sun Yang Xu | 2017 | Journal of Semiconductors2017，38，3： | 1 |
| 12 | Patterned glass ceramic design for high-brightness high-color-quality laser-driven lightings显示文摘Up-to-date laser-driven lightings confront a challenge of simultaneously achieving good photometric and chromatic performances.Herein,the coupling of“patterned package design”and“phosphor wheel”was proposed and demonstrated effectively to deal with this tough issue,based on a new architecture of CaAlSiN3:Eu2+(CASN:Eu)glass ceramic film(GCF)on Y_(3)Al_(5)O_(12):Ce^(3+)(YAG:Ce)GC plate.The fabricated composite has no interface between the two functional layers and retains the admirable luminescent features from CASN:Eu and YAG:Ce for the microstructural integrity during co-sintering.The studies on laser-microcrystalline interactions reveal that the luminescence saturation is almost determined by thermal quenching for YAG:Ce,but is ascribed to thermal/intensity quenching which are equally crucial for CASN:Eu.Benefiting from the elaborate architecture design,good color chromaticity tunability was obtained,and severe photon reabsorption was reduced.Moreover,accompanied with the rotation induced increase of thermal convection to air and pulse-like excitation,the constructed lighting engine under blue laser driven shows bright white light with luminous flux(LF)higher than 1000 lm,adjustable chromaticity from cool to warm,and improved color rendering index(CRI)approaching to 70. | Qiugui HUANG Hang LIN Bo WANG Shisheng LIN Pengfei WANG Ping SUI Ju XU Yao CHENG Yuansheng WANG | 2022 | Journal of Advanced Ceramics2022，11，6： | 1 |
| 13 | An aero-engine life-cycle maintenance policy optimization algorithm: Reinforcement learning approach显示文摘An aero-engine maintenance policy plays a crucial role in reasonably reducing maintenance cost. An aero-engine is a type of complex equipment with long service-life. In engineering,a hybrid maintenance strategy is adopted to improve the aero-engine operational reliability. Thus,the long service-life and the hybrid maintenance strategy should be considered synchronously in aero-engine maintenance policy optimization. This paper proposes an aero-engine life-cycle maintenance policy optimization algorithm that synchronously considers the long service-life and the hybrid maintenance strategy. The reinforcement learning approach was adopted to illustrate the optimization framework, in which maintenance policy optimization was formulated as a Markov decision process. In the reinforcement learning framework, the Gauss–Seidel value iteration algorithm was adopted to optimize the maintenance policy. Compared with traditional aero-engine maintenance policy optimization methods, the long service-life and the hybrid maintenance strategy could be addressed synchronously by the proposed algorithm. Two numerical experiments and algorithm analyses were performed to illustrate the optimization algorithm in detail. | Zhen LI Shisheng ZHONG Lin LIN | 2019 | Chinese Journal of Aeronautics2019，32，9： | 1 |

| 15 | Ultra-stable and color-tunable manganese ions doped lead-free cesium zinc halides nanocrystals in glasses for light-emitting applications显示文摘All inorganic CsPbX_(3)(X=Cl,Br,and I)perovskite nanocrystals have made unprecedented radical progresses for opto-electronic applications,but their instability and toxicity of lead impede their wide applications.Herein,we report the first precipitation of leadfree Mn:Cs_(2)ZnX_(4) nanocrystals in glasses.Efficient green and red photoluminescence are realized from these Mn:Cs_(2)ZnX_(4 )nanocrystals in glasses.By adjusting the size and halide component in these nanocrystals,coordination environment of Mn^(2+)ions can be tuned,leading to tunable photoluminescence with improved quantum efficiency.It is illustrated that in-situ precipitation of these Mn:Cs_(2)ZnX_(4) nanocrystals in glasses significantly improves their thermal-,chemical-,and photo-stabilities,making them promising for light-emitting diodes with stable chromaticity coordinates. | Kai Li Ying Ye Wenchao Zhang Yao Zhou Yudong Zhang Shisheng Lin Hang Lin Jian Ruan Chao Liu | 2022 | Nano Research2022，15，10： | 1 |

| 18 | Diverse foraging strategies of breeding Swinhoe's Storm-petrel in the productive marginal sea of the Northwest Pacific显示文摘Understanding the foraging behavior is essential for investigating seabird ecology and conservation,as well as monitoring the well-being of the marine environment.Breeding seabirds adopt diverse foraging strategies to maximize energy gains and cope with the intensified challenges of parenting and self-maintenance.Such tradeoff may stem from the heterogeneity of food resources and the constraints of central place foraging.Nevertheless,abundant marine productivity could alleviate the energy limitation for seabirds,resulting in a consistent foraging approach.Here,we investigated the foraging strategy during the breeding season of a cryptic small-sized seabird,Swinhoe’s Storm-petrel(Hydrobates monorhis),in the Yellow Sea,a productive marginal sea of the Northwest Pacific.Using GPS tracking,we evaluated habitat preference,quantified the foraging strategy,and tested if environmental conditions and individual traits influence foraging trips.We found that Swinhoe’s Storm-petrels preferred nearshore areas with shallow water and engaged in primarily short foraging trips.Distinctive southeastward and southwestward strategies emerged when combining trip metrics,including foraging direction,duration,and maximum distance.The bathymetry,proximity to the coastline,and sea surface temperature differed in two foraging strategies.Foraging strategies exhibited flexibility between individuals,potentially explained by wing morphology,in which longer-winged birds are more likely to embark on longer-distance foraging trips.These findings highlight the impact of environmental factors and individual traits on seabirds’foraging decisions in productive marginal sea ecosystems.Our study also provides valuable insights into the foraging ecology of this Asian endemic storm-petrel. | Yachang Cheng Lei Zhu Lin Xue Shisheng Ma Nan Jia Shaoping Zang Zhihai Cao Jing Yuan Yang Liu | 2024 | Avian Research2024，15，1： | 0 |
| 19 | Proteomic characterization of four subtypes of M2 macrophages derived from human THP-1 cells显示文摘Macrophages are widely distributed immune cells that contribute to tissue homeostasis.Human THP-1 cells have been widely used in various macrophage-associated studies,especially those involving pro-inflammatory M1 and anti-inflammatory M2 phenotypes.However,the molecular characterization of four M2 subtypes(M2a,M2b,M2c,and M2d)derived from THP-1has not been fully investigated.In this study,we systematically analyzed the protein expression profiles of human THP-1-derived macrophages(M0,M1,M2a,M2b,M2c,and M2d)using quantitative proteomics approaches.The commonly and specially regulated proteins of the four M2 subtypes and their potential biological functions were further investigated.The results showed that M2a and M2b,and M2c and M2d have very similar protein expression profiles.These data could serve as an important resource for studies of macrophages using THP-1 cells,and provide a reference to distinguish different M2 subtypes in macrophage-associated diseases for subsequent clinical research. | Pengfei LI Chen MA Jing LI Shanshan YOU Liuyi DANG Jingyu WU Zhifang HAO Jun LI Yuan ZHI Lin CHEN Shisheng SUN | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，5： | 0 |
