| 1 | Research on Formation Mechanisms of Hot Dry Rock Resources in China显示文摘As an important geothermal resource, hot dry rock(HDR) reserves have been studied in many countries. HDR resources in China have huge capacity and have become one of the most important resources for the potential replacement of fossil fuels. However, HDR resources are difficult to develop and utilise. Technologies for use with HDR, such as high–temperature drilling, reservoir characterisation, reservoir fracturing, microseismic monitoring and high–temperature power stations, originate from the field of oil and drilling. Addressing how to take advantage of these developed technologies is a key factor in the development of HDR reserves. Based on the thermal crustal structure in China, HDR resources can be divided into four types: high radioactive heat production, sedimentary basin, modern volcano and the inner–plate active tectonic belt. The prospective regions of HDR resources are located in South Tibet, West Yunnan, the southeast coast of China, Bohai Rim, Songliao Basin and Guanzhong Basin. The related essential technologies are relatively mature, and the prospect of HDR power generation is promising. Therefore, analysing the formation mechanisms of HDR resources and promoting the transformation of technological achievements, large–scale development and the utilisation of HDR resources can be achieved in China. | WANG Guiling LIN Wenjing ZHANG Wei LU Chuan MA Feng GAN Haonan | 2016 | Acta Geologica Sinica(English Edition)2016，90，4： | 14 |
| 2 | Endothelial CDS2 deficiency causes VEGFA-mediated vascular regression and tumor inhibition显示文摘The response of endothelial cells to signaling stimulation is critical for vascular morphogenesis,homeostasis and function.Vascular endothelial growth factor-a(VEGFA)has been commonly recognized as a pro-angiogenic factor in vertebrate developmental,physiological and pathological conditions for decades.Here we report a novel finding that genetic ablation of CDP-diacylglycerol synthetase-2(CDS2),a metabolic enzyme that controls phosphoinositide recycling,switches the output of VEGFA signaling from promoting angiogenesis to unexpectedly inducing vessel regression.Live imaging analysis uncovered the presence of reverse migration of the angiogenic endothelium in cds2 mutant zebrafish upon VEGFA stimulation,and endothelium regression also occurred in postnatal retina and implanted tumor models in mice.In tumor models,CDS2 deficiency enhanced the level of tumorsecreted VEGFA,which in-turn trapped tumors into a VEGFA-induced vessel regression situation,leading to suppression of tumor growth.Mechanistically,VEGFA stimulation reduced phosphatidylinositol(4,5)-bisphosphate(PIP2)availability in the absence of CDS2-controlled-phosphoinositide metabolism,subsequently causing phosphatidylinositol(3,4,5)-triphosphate(PIP3)deficiency and F0X01 activation to trigger regression of CDS2-null endothelium.Thus,our data indicate that the effect of VEGFA on vasculature is context-dependent and can be converted from angiogenesis to vascular regression. | Wencao Zhao Le Cao Hanru Ying Wenjuan Zhang Dantong Li Xiaolong Ziiu Wenzhi Xue Shuang Wu Mengye Cao Cong Fu Haonan Qi Yimei Hao Yun-Chi Tang Jun Qin Tao PZhong Xiaoxi Lin Luyang Yu Xuri Li Lin Li Dianqing Wu Weijun Pan | 2019 | Cell Research2019，29，11： | 9 |
| 3 | Heat Aggregation Mechanisms of Hot Dry Rocks Resources in the Gonghe Basin, Northeastern Tibetan Plateau显示文摘Hot dry rock(HDR) is an important geothermal resource and clean energy source that may play an increasingly important role in future energy management. High-temperature HDR resources were recently detected in deep regions of the Gonghe Basin on the northeastern edge of the Tibetan Plateau, which led to a significant breakthrough in HDR resource exploration in China. This research analyzes the deep temperature distribution, radiogenic heat production, heat flow, and crustal thermal structure in the Qiaboqia Valley, Guide Plain, and Zhacanggou area of the Gonghe Basin based on geothermal exploration borehole logging data, rock thermophysical properties, and regional geophysical exploration data. The results are applied to discuss the heat accumulation mechanism of the HDR resources in the Gonghe Basin. The findings suggest that a low-velocity layer in the thickened crust of the Tibetan Plateau provides the most important source of constant intracrustal heat for the formation of HDR resources in the Gonghe Basin, whereas crustal thickening redistributes the concentrated layer of radioactive elements, which compensates for the relatively low heat production of the basal granite and serves as an important supplement to the heat of the HDR resources. The negative effect is that the downward curvature of the lithospheric upper mantle caused by crustal thickening leads to a small mantle heat flow component. As a result, the heat flows in the Qiaboqia Valley and Guide Plain of the Gonghe Basin are 106.2 and 77.6 m W/m2, respectively, in which the crust-mantle heat flow ratio of the former is 3.12:1, indicating a notably anomalous intracrustal thermal structure. In contrast, the crust-mantle heat flow ratio in the Guide Plain is 1.84:1, which reflects a typical hot crust-cold mantle thermal structure. The Guide Plain and Zhacanggou area show the same increasing temperature trend with depth, which reflects that their geothermal backgrounds and deep high-temperature environments are similar. These results provide important insight on the heat source mechanism of HDR resource formation in the Tibetan Plateau and useful guidance for future HDR resource exploration projects and target sites selection in similar areas. | LIN Wenjing WANG Guiling ZHANG Shengsheng ZHAO Zhen XING Linxiao GAN Haonan TAN Xianfeng | 2021 | Acta Geologica Sinica(English Edition)2021，95，6： | 5 |
| 4 | Hydrothermal Systems Characterized by Crustal Thermally-dominated Structures of Southeastern China显示文摘Southeastern China(SE China)is located in the Pacific tectonic domain and has experienced a series of tectono-magmatic events induced by the subduction of the Paleo-Pacific Plate since the late Mesozoic.The subduction formed a series of NE-NNE oriented faults under a NW-SE regional stress field,along which a number of thermal springs occur.Previous studies have focused on the genesis mechanism of specific geothermal fields in SE China,but the general characteristics of hydrothermal systems in SE China remains unclear.In this study,we investigate the correlation between geothermal activity,hydrochemical type and regional faults by studying the distribution of hydrothermal activity and geochemical properties of typical hydrothermal systems in SE China.The hydrothermal systems in SE China have a crustal thermally-dominated structural origin unique to the specific geological and tectonic conditions of the Eurasian Plate margin.The upwelling of the asthenosphere and the widespread granitoids with high radiogenic heat production in SE China provide major heat sources for regional geothermal anomalies.The NE-oriented crustal thermally-dominated faults are critical for the formation of geothermal anomalies and NW-oriented extensional faults have created favorable conditions for meteoric water infiltration,transportation and the formation of thermal springs. | WANG Guiling GAN Haonan LIN Wenjing YUE Gaofan YAN Xiaoxue LI Tingxin ZHANG Wei MA Feng | 2023 | Acta Geologica Sinica(English Edition)2023，97，4： | 2 |
| 5 | 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 |
| 6 | 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 |
| 7 | 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 |
| 8 | Carbon-coated Ni-Co alloy catalysts:preparation and performance for in-situ aqueous phase hydrodeoxygenation of methyl palmitate to hydrocarbons using methanol as the hydrogen donor显示文摘Carbon-coated Ni,Co and Ni-Co alloy catalysts were prepared by the carbonization of the metal doped resorcinol-formaldehyde resins synthesized by the one-pot extended Stöber method.It was found that the introduction of Co remarkably reduced the carbon microsphere size.The metallic Ni,Co,and Ni-Co alloy particles(mainly 10-12 nm)were uniformly distributed in carbon microspheres.A charge transfer from Ni to Co appeared in the Ni-Co alloy.Compared with those of metallic Ni and Co,the d-band center of the Ni-Co alloy shifted away from and toward the Fermi level,respectively.In the in-situ aqueous phase hydrodeoxygenation of methyl palmitate with methanol as the hydrogen donor at 330℃,the decarbonylation/decarboxylation pathway dominated on all catalysts.The Ni-Co@C catalysts gave higher activity than the Ni@C and Co@C catalysts,and the yields of n-pentadecane and n-C6-n-C16 reached 71.6%and 92.6%,respectively.The excellent performance of Ni-Co@C is attributed to the electronic interactions between Ni and Co and the small carbon microspheres.Due to the confinement effect of carbon,the metal particles showed high resistance to sintering under harsh hydrothermal conditions.Catalyst deactivation is due to the carbonaceous deposition,and the regeneration with CO_(2) recovered the catalyst reactivity. | Yinteng Shi Lin Ai Haonan Shi Xiaoyu Gu Yujun Han Jixiang Chen | 2022 | Frontiers of Chemical Science and Engineering2022，16，4： | 0 |
| 9 | A fluorescent film sensor for high-performance detection of Listeria monocytogenes via vapor sampling显示文摘Foodborne Listeria monocytogenes poses serious threats to public health.Fast and sensitive detection of the pathogen at the point of contamination is thus crucial to halt the spread of bacteria-related diseases.Herein,we report for the first time a fluorescent film sensor to detect the biomarker of L.monocytogenes,3-hydroxy-2-butanone.The sensor demonstrated unprecedented sensing performance for the analyte with a detection limit lower than 0.05 mg/m^(3),response time less than 1 s,full reversibility,and excellent selectivity.Further study showed that the sensor can be used to monitor the growth of L.monocytogenes with much-improved sensitivity.The superior performance of the sensor is ascribed to the specific binding,efficient charge transfer emission,and porous adlayer structure of the specially designed sensing fluorophore-based film.Our work paves the way to develop a portable detector to meet the needs for on-site and real-time detection of foodborne pathogens. | Rongrong Huang Meiqi Li Dehui Lin Yangtao Shao Congdi Shang Qianqian Liu Guijun Liu Nan Li Rong Miao Haonan Peng Yanli Tang Yu Fang | 2023 | Aggregate2023，4，1： | 0 |
| 10 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 12 | Distributed Multi-Cell Multi-User MISO Downlink Beamforming via Deep Reinforcement Learning显示文摘The sum rate maximization beamforming problem for a multi-cell multi-user multiple-input single-output interference channel(MISO-IC)system is considered.Conventionally,the centralized and distributed beamforming solutions to the MISO-IC system have high computational complexity and bear a heavy burden of channel state information exchange between base stations(BSs),which becomes even much worse in a large-scale antenna system.To address this,we propose a distributed deep reinforcement learning(DRL)based approach with lim⁃ited information exchange.Specifically,the original beamforming problem is decomposed of the problems of beam direction design and power allocation and the costs of information exchange between BSs are significantly reduced.In particular,each BS is provided with an inde⁃pendent deep deterministic policy gradient network that can learn to choose the beam direction scheme and simultaneously allocate power to users.Simulation results illustrate that the proposed DRL-based approach has comparable sum rate performance with much less information exchange over the conventional distributed beamforming solutions. | JIA Haonan HE Zhenqing TAN Wanlong RUI Hua LIN Wei | 2022 | ZTE Communications2022，20，4： | 0 |

| 14 | Deep reinforcement learning and 3D physical environments applied to crowd evacuation in congested scenarios显示文摘To avoid crowd evacuation simulations depending on 2D environments and real data,we propose a framework for crowd evacuation modeling and simulation by applying deep reinforcement learning(DRL)and 3D physical environments(3DPEs).In 3DPEs,we construct simulation scenarios from the aspects of geometry,semantics and physics,which include the environment,the agents and their interactions,and provide training samples for DRL.In DRL,we design a double branch feature extraction combined actor and critic network as the DRL policy and value function and use a clipped surrogate objective with polynomial decay to update the policy.With a unified configuration,we conduct evacuation simulations.In scenarios with one exit,we reproduce and verify the bottleneck effect of congested crowds and explore the impact of exit width and agent characteristics(number,mass and height)on evacuation.In scenarios with two exits and a uniform(nonuniform)distribution of agents,we explore the impact of exit characteristics(width and relative position)and agent characteristics(height,initial location and distribution)on agent exit selection and evacuation.Overall,interactive 3DPEs and unified DRL enable agents to adapt to different evacuation scenarios to simulate crowd evacuation and explore the laws of crowd evacuation. | Dong Zhang Wenhang Li Jianhua Gong Guoyong Zhang Jiantao Liu Lin Huang Heng Liu Haonan Ma | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 15 | Response of ecosystem carbon storage to land use change from 1985 to 2050 in the Ningxia Section of Yellow River Basin,China显示文摘Regional sustainable development necessitates a holistic understanding of spatiotemporal variations in ecosystem carbon storage(ECS),particularly in ecologically sensitive areas with arid and semi-arid climate.In this study,we calculated the ECS in the Ningxia Section of Yellow River Basin,China from 1985 to 2020 using the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST)model based on land use data.We further predicted the spatial distribution of ECS in 2050 under four land use scenarios:natural development scenario(NDS),ecological protection scenario(EPS),cultivated land protection scenario(CPS),and urban development scenario(UDS)using the patch-generating land use simulation(PLUS)model,and quantified the influences of natural and human factors on the spatial differentiation of ECS using the geographical detector(Geodetector).Results showed that the total ECS of the study area initially increased from 1985 until reaching a peak at 402.36×10^(6) t in 2010,followed by a decreasing trend to 2050.The spatial distribution of ECS was characterized by high values in the eastern and southern parts of the study area,and low values in the western and northern parts.Between 1985 and 2020,land use changes occurred mainly through the expansion of cultivated land,woodland,and construction land at the expense of unused land.The total ECS in 2050 under different land use scenarios(ranked as EPS>CPS>NDS>UDS)would be lower than that in 2020.Nighttime light was the largest contributor to the spatial differentiation of ECS,with soil type and annual mean temperature being the major natural driving factors.Findings of this study could provide guidance on the ecological construction and high-quality development in arid and semi-arid areas. | LIN Yanmin HU Zhirui LI Wenhui CHEN Haonan WANG Fang NAN Xiongxiong YANG Xuelong ZHANG Wenjun | 2024 | Journal of Arid Land2024，16，1： | 0 |
| 16 | Self-powered flexible fingerprint-recognition display based on a triboelectric nanogenerator显示文摘In the time of Internet of Things(IoT),alternating current electroluminescence(ACEL)has unique advantages in the fields of smart display and human–computer interaction.However,their reliance on external high-voltage AC power supplies poses challenges in terms of wearability and limits their practical application.This paper proposed an innovative scheme for preparing a feather triboelectric nanogenerator(F-TENG)using recyclable and environmentally friendly material.The highest open-circuit voltage,short-circuit current,and transferred charge of SF6-treated F-TENGs can reach 449 V,63μA,and 152 nC,which enables easy lighting of BaTiO_(3)^(-)doped ACEL devices.Using a human electrical potential,a single-electrode F-TENG is combined with ACEL device for self-powered fingerprint recognition display.These works achieve self-powered flexible wearable ACEL devices,which are not only efficient and portable but also have good application prospects in the human–computer interaction,functional displays,and wearable electronic devices. | Wandi Chen Haonan Wang Yibin Lin Xinyan Gan Heng Tang Yongai Zhang Qun Yan Tailiang Guo Xiongtu Zhou Chaoxing Wu | 2024 | Nano Research2024，17，4： | 0 |
| 17 | Spectroscopic stimulated Raman scattering imaging of highly dynamic specimens through matrix completion显示文摘Spectroscopic stimulated Raman scattering(SRS)imaging generates chemical maps of intrinsic molecules,with no need for prior knowledge.Despite great advances in instrumentation,the acquisition speed for a spectroscopic SRS image stack is fundamentally bounded by the pixel integration time.In this work,we report three-dimensional sparsely sampled spectroscopic SRS imaging that measures~20%of pixels throughout the stack.In conjunction with related work in low-rank matrix completion(e.g.,the Netflix Prize),we develop a regularized non-negative matrix factorization algorithm to decompose the sub-sampled image stack into spectral signatures and concentration maps.This design enables an acquisition speed of 0.8 s per image stack,with 50 frames in the spectral domain and 40,000 pixels in the spatial domain,which is faster than the conventional raster laser-scanning scheme by one order of magnitude.Such speed allows real-time metabolic imaging of living fungi suspended in a growth medium while effectively maintaining the spatial and spectral resolutions.This work is expected to promote broad application of matrix completion in spectroscopic laser-scanning imaging. | Haonan Lin Chien-Sheng Liao Pu Wang Nan Kong Ji-Xin Cheng | 2017 | Light(Science & Applications)2017，6，1： | 0 |
| 18 | Ionization Engineering of Hydrogels Enables Highly Efficient Salt‑Impeded Solar Evaporation and Night‑Time Electricity Harvesting显示文摘Interfacial solar evaporation holds immense potential for brine desalination with low carbon footprints and high energy utilization.Hydrogels,as a tunable material platform from the molecular level to the macroscopic scale,have been considered the most promising candidate for solar evaporation.However,the simultaneous achievement of high evaporation efficiency and satisfactory tolerance to salt ions in brine remains a challenging scientific bottleneck,restricting the widespread application.Herein,we report ionization engineering,which endows polymer chains of hydrogels with electronegativity for impeding salt ions and activating water molecules,fundamentally overcoming the hydrogel salt-impeded challenge and dramatically expediting water evaporating in brine.The sodium dodecyl benzene sulfonate-modified carbon black is chosen as the solar absorbers.The hydrogel reaches a ground-breaking evaporation rate of 2.9 kg m−2 h−1 in 20 wt%brine with 95.6%efficiency under one sun irradiation,surpassing most of the reported literature.More notably,such a hydrogel-based evaporator enables extracting clean water from oversaturated salt solutions and maintains durability under different high-strength deformation or a 15-day continuous operation.Meantime,on the basis of the cation selectivity induced by the electronegativity,we first propose an all-day system that evaporates during the day and generates salinity-gradient electricity using waste-evaporated brine at night,anticipating pioneer a new opportunity for all-day resource-generating systems in fields of freshwater and electricity. | Nan He Haonan Wang Haotian Zhang Bo Jiang Dawei Tang Lin Li | 2024 | Nano-Micro Letters2024，16，1： | 0 |
| 19 | Raman amplification at 2.2μm in silicon core fibers with prospects for extended mid-infrared source generation显示文摘Raman scattering provides a convenient mechanism to generate or amplify light at wavelengths where gain is not otherwise available.When combined with recent advancements in high-power fiber lasers that operate at wavelengths~2μm,great opportunities exist for Raman systems that extend operation further into the mid-infrared regime for applications such as gas sensing,spectroscopy,and biomedical analyses.Here,a thulium-doped fiber laser is used to demonstrate Raman emission and amplification from a highly nonlinear silicon core fiber(SCF)platform at wavelengths beyond 2μm.The SCF has been tapered to obtain a micrometer-sized core diameter(~1.6μm)over a length of 6 cm,with losses as low as 0.2 dB cm^(−1).A maximum on-off peak gain of 30.4 dB was obtained using 10 W of peak pump power at 1.99μm,with simulations indicating that the gain could be increased to up to~50 dB by extending the SCF length.Simulations also show that by exploiting the large Raman gain and extended mid-infrared transparency of the SCF,cascaded Raman processes could yield tunable systems with practical output powers across the 2–5μm range. | Meng Huang Shiyu Sun Than S.Saini Qiang Fu Lin Xu Dong Wu Haonan Ren Li Shen Thomas W.Hawkins John Ballato Anna C.Peacock | 2023 | Light(Science & Applications)2023，12，10： | 0 |
| 20 | Polarized Water Driven Dynamic PN Junction-Based Direct-Current Generator显示文摘There is a rising prospective in harvesting energy from the environment,as in situ energy is required for the distributed sensors in the interconnected information society,among which the water flow energy is the most potential candidate as a clean and abundant mechanical source.However,for microscale and unordered movement of water,achieving a sustainable direct-current generating device with high output to drive the load element is still challenging,which requires for further exploration.Herein,we propose a dynamic PN water junction generator with moving water sandwiched between two semiconductors,which outputs a sustainable direct-current voltage of 0.3 V and a current of 0.64μA.The mechanism can be attributed to the dynamic polarization process of water as moving dielectric medium in the dynamic PN water junction,under the Fermi level difference of two semiconductors.We further demonstrate an encapsulated portable power-generating device with simple structure and continuous direct-current voltage output of 0.11 V,which exhibits its promising potential application in the field of wearable devices and the IoTs. | Yanghua Lu Yanfei Yan Xutao Yu Xu Zhou Sirui Feng Chi Xu Haonan Zheng Zunshan Yang Linjun Li Kaihui Liu Shisheng Lin | 2021 | Research2021，，1： | 0 |
