| 1 | Using coupling slabs to tailor surface-acoustic-wave band structures in phononic crystals consisting of pillars attached to elastic substrates显示文摘The propagation of surface acoustic waves(SAWs) in two-dimensional phononic crystals(PnCs) with and without coupling-enhancement slabs was theoretically investigated using a three-dimensional finite element method.Different piezoelectric substrates,for example,lithium niobate(LiNbO_3),gallium nitride(GaN),and aluminium nitride(A1N),were taken into account.Compared to the PnCs without coupling-enhancement slabs,the coupling between each pillar and its nearest neighbor was largely enhanced in the presence of slabs.The bandwidth of the first directional band gap increased markedly compared with its initial value for the PnCs without a slab(within square symmetry).In addition,with increasing thicknesses of the slabs bonded between neighboring pillars,the first directional band-gap and second directional band gap of the PnCs tend to merge.Therefore,the structure with coupling-enhancement slabs can be used as an excellent electrical band elimination filter for most electro-SAW devices,offering a new strategy to realize chip-scale applications in electroacoustic signal processing,optoacoustic modulation,and even SAW microfluidic devices. | Heng Zhang SiYuan Yu FuKang Liu Zhen Wang MingHui Lu XiaoBo Hu YanFeng Chen XianGang Xu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，4： | 3 |

| 3 | Construction of Photoresponsive 3D Structures Based on Triphenylethylene Photochromic Building Blocks显示文摘Photoresponsive materials have been widely used in sensing,bioimaging,molecular switches,information storage,and encryption nowadays.Although a large amount of photoresponsive materials have been reported,the construction of these smart materials into precisely prescribed complex 3D geometries is rarely studied.Here we designed a novel photoresponsive material methyl methacrylate containing triphenylethylene(TrPEF_(2)-MA)that can be directly used for digital light processing(DLP)3D printing.Based on TrPEF_(2)-MA,a series of photoresponsive 3D structures with reversible color switching under ultraviolet/visible light irradiations were fabricated.These complex photoresponsive 3D structures show high resolutions(50μm),excellent repeatability(25 cycles without fatigue),and tunable saturate color degrees.Multicomponent DLP 3D printing processes were also carried out to demonstrate their great properties in information hiding and information-carrying properties.This design strategy for constructing photoresponsive 3D structures is attractive in the area of adaptive camouflage,information hiding,information storage,and flexible electronics. | Xiayu Zhang Fukang Liu Beibei Du Rongjuan Huang Simin Zhang Yunfei He Hailan Wang Jingjing Cui Biao Zhang Tao Yu Wei Huang | 2022 | Research2022，，4： | 1 |
| 4 | The Circadian System Is Essential for the Crosstalk of VEGF-Notch-mediated Endothelial Angiogenesis in Ischemic Stroke显示文摘Ischemic stroke is a major public health problem worldwide.Although the circadian clock is involved in the process of ischemic stroke,the exact mechanism of the circadian clock in regulating angiogenesis after cerebral infarction remains unclear.In the present study,we determined that environmental circadian disruption(ECD)increased the stroke severity and impaired angiogenesis in the rat middle cerebral artery occlusion model,by measuring the infarct volume,neurological tests,and angiogenesis-related protein.We further report that Bmal1 plays an irreplaceable role in angiogenesis.Overexpression of Bmal1 promoted tube-forming,migration,and wound healing,and upregulated the vascular endothelial growth factor(VEGF)and Notch pathway protein levels.This promoting effect was reversed by the Notch pathway inhibitor DAPT,according to the results of angiogenesis capacity and VEGF pathway protein level.In conclusion,our study reveals the intervention of ECD in angiogenesis in ischemic stroke and further identifies the exact mechanism by which Bmal1 regulates angiogenesis through the VEGF-Notch1 pathway. | Yuxing Zhang Xin Zhao Chun Guo Ying Zhang Fukang Zeng Qian Yin Zhong Li Le Shao Desheng Zhou Lijuan Liu | 2023 | Neuroscience Bulletin2023，39，9： | 1 |

| 7 | Intrinsically stretchable polymer semiconductor based electronic skin for multiple perceptions of force,temperature,and visible light显示文摘As a stretchable seamless device,electronic skin(E-skin)has drawn enormous interest due to its skin-like sensing capability.Besides the basic perception of force and temperature,multiple perception that is beyond existing functions of human skin is becoming an important direction for E-skin developments.However,the present E-skins for multiple perceptions mainly rely on different sensing materials and heterogeneous integration,resulting in a complex device structure.Additionally,their stretchability is usually achieved by the complicated microstructure design of rigid materials.Here,we report an intrinsically stretchable polymer semiconductor based E-skin with a simple structure for multiple perceptions of force,temperature,and visible light.The E-skin is on the basis of poly(3-hexylthiophene)(P3HT)nanofibers percolated polydimethylsiloxane(PDMS)composite polymer semiconductor,which is fabricated by a facile solution method.The E-skin shows reliable sensing capabilities when it is used to perceive strain,pressure,temperature,and visible light.Based on the E-skin,an intelligent robotic hand sensing and controlling system is further demonstrated.Compared with conventional E-skins for multiple perceptions,this E-skin only has a simple monolayer sensing membrane without the need of combining different sensing materials,heterogeneous integration,and complicated microstructure design.Such a strategy of utilizing intrinsically stretchable polymer semiconductor to create simple structured E-skin for multiple perceptions will promote the development of E-skins in a broad application scenario,such as artificial robotic skins,virtual reality,intelligent gloves,and biointegrated electronics. | Dongjuan Liu Pengcheng Zhu Fukang Zhang Peishuo Li Wenhao Huang Chang Li Ningning Han Shuairong Mu Hao Zhou Yanchao Mao | 2023 | Nano Research2023，16，1： | 0 |
| 8 | Pulse repetition-rate effect on the intensity inside a femtosecond laser filament in air显示文摘As intense,ultrashort,kHz-repetition-rate laser systems become commercially available,pulse cumulative effects are critical for laser filament-based applications.In this work,the pulse repetition-rate effect on femtosecond laser filamentation in air was investigated both numerically and experimentally.The pulse repetition-rate effect has negligible influence at the leading edge of the filament.Clear intensity enhancement from a high-repetition pulse is observed at the peak and tailing edge of the laser filament.As the repetition rate of the laser pulses increases from 100 to 1000 Hz,the length of the filament extends and the intensity inside the filament increases.A physical picture based on the pulse repetition-rate dependent‘low-density hole’effect on filamentation is proposed to explain the obtained results well. | Fukang Yin Juan Long Yaoxiang Liu Yingxia Wei Bin Zhu Kainan Zhou Tie-Jun Wang Yuxin Leng Ruxin Li | 2023 | High Power Laser Science and Engineering2023，11，4： | 0 |
| 9 | A DHR executor selection algorithm based on historical credibility and dissimilarity clustering显示文摘The security of the dynamic heterogeneous redundancy(DHR)architecture relies on the heterogeneity of its executors,which also defines the vulnerability of the mimic system.In order to select executors with reliable and significant dissimilarity as service executors,we propose a DHR executor selection algorithm based on historical credibility and dissimilarity clustering(HCDC),which adds two metrics of executor historical credibility and dissimilarity.First,to maximize the difference between heterogeneous executor pools,clustering is performed based on the dissimilarity of the executor.Second,the executor with the highest historical credibility is selected from the heterogeneous executor pool as the candidate pool.The historical credibility is dynamically updated by the negative feedback control based on the results of the multi-mode adjudicator.Finally,the dynamic scheduling algorithm selects the executors from the candidate pool to form the set of service executors.The simulation results demonstrate that,in comparison to existing methods,the algorithm reduces the attack success rate and average failure rate while increasing system reliability. | Sisi SHAO Yimu JI Weili ZHANG Shangdong LIU Fei JIANG Zhigang CAO Fei WU Fukang ZENG Jun ZUO Longfei ZHOU | 2023 | Science China(Information Sciences)2023，66，11： | 0 |
| 10 | Moderate Fields, Maximum Potential: Achieving High Records with Temperature‑Stable Energy Storage in Lead‑Free BNT‑Based Ceramics显示文摘The increasing awareness of environmental concerns has prompted a surge in the exploration of leadfree,high-power ceramic capacitors.Ongoing efforts to develop leadfree dielectric ceramics with exceptional energystorage performance(ESP)have predominantly relied on multicomponent composite strategies,often accomplished under ultrahigh electric fields.However,this approach poses challenges in insulation and system downsizing due to the necessary working voltage under such conditions.Despite extensive study,bulk ceramics of(Bi_(0.5)Na_(0.5))TiO_(3)(BNT),a prominent lead-free dielectric ceramic family,have seldom achieved a recoverable energy-storage(ES)density(Wrec)exceeding 7 J cm^(−3).This study introduces a novel approach to attain ceramic capacitors with high ESP under moderate electric fields by regulating permittivity based on a linear dielectric model,enhancing insulation quality,and engineering domain structures through chemical formula optimization.The incorporation of SrTiO_(3)(ST)into the BNT matrix is revealed to reduce the dielectric constant,while the addition of Bi(Mg_(2/3)Nb_(1/3))O_(3)(BMN)aids in maintaining polarization.Additionally,the study elucidates the methodology to achieve high ESP at moderate electric fields ranging from 300 to 500 kV cm^(−1).In our optimized composition,0.5(Bi_(0.5)Na_(0.4)K_(0.1))TiO_(3)–0.5(2/3ST-1/3BMN)(B-0.5SB)ceramics,we achieved a Wrec of 7.19 J cm^(−3) with an efficiency of 93.8%at 460 kV cm^(−1).Impressively,the B-0.5SB ceramics exhibit remarkable thermal stability between 30 and 140℃ under 365 kV cm^(−1),maintaining a Wrec exceeding 5 J cm^(−3).This study not only establishes the B-0.5SB ceramics as promising candidates for ES materials but also demonstrates the feasibility of optimizing ESP by modifying the dielectric constant under specific electric field conditions.Simultaneously,it provides valuable insights for the future design of ceramic capacitors with high ESP under constraints of limited electric field. | Wenjing Shi Leiyang Zhang Ruiyi Jing Yunyao Huang Fukang Chen Vladimir Shur Xiaoyong Wei Gang Liu Hongliang Du Li Jin | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 11 | Achieving high dielectric energy-storage properties through a phase coexistence design and viscous polymer process in BNT-based ceramics显示文摘In the last few decades,dielectric capacitors have gotten a lot of attention because they can store more power and charge and discharge very quickly.But it has a low energy-storage density(Wrec),efficiency(h),and temperature stability.By adding Pb(Mg1/3Nb2/3)O3(PMN)and(Bi0$1Sr0.85)TiO3(BST)to a nonstoichiometric(Bi0$51Na0.5)TiO3(BNT)matrix,the goal is to change the phase transition properties and make the material more relaxor ferroelectric(RFE)by lowering the remnant polarization Pr and keeping the maximum polarization Pmax.A viscous polymer process(VPP)is used to improve the electric breakdown strength,which is also a key part of being able to store energy.By working together,ceramics with the formula 0.79[0.85BNT-0.15PMN]-0.21BST(BP-0.21BST)are made.The phase structure has been changed from a rhombohedral phase to a rhombohedral-tetragonal coexisted phase.This is beneficial for RFE properties and gives a Wrec of 6.45 J/cm^(3) and a h of 90%at 400 kV/cm.Also,the energy-storage property is very temperature stable between 30 and 150C.These results show that process optimization and composition design can be used to improve the energy storage properties,and that the dielectric ceramic materials made can be used in high-powder pulse dielectric capacitors. | Yule Yang Juanjuan Wang Ruiyi Jing Wenjing Shi Leiyang Zhang Chao Li Xinyu Zeng Fukang Chen Gang Liu Xiaolian Chao Yan Yan Li Jin | 2023 | Journal of Materiomics2023，9，6： | 0 |
| 12 | Stable,intense supercontinuum light generation at 1 kHz by electric field assisted femtosecond laser filamentation in air显示文摘Supercontinuum(SC)light source has advanced ultrafast laser spectroscopy in condensed matter science,biology,physics,and chemistry.Compared to the frequently used photonic crystal fibers and bulk materials,femtosecond laser filamentation in gases is damage-immune for supercontinuum generation.A bottleneck problem is the strong jitters from filament induced self-heating at kHz repetition rate level.We demonstrated stable kHz supercontinuum generation directly in air with multiple mJ level pulse energy.This was achieved by applying an external DC electric field to the air plasma filament.Beam pointing jitters of the 1 kHz air filament induced SC light were reduced by more than 2 fold.The stabilized high repetition rate laser filament offers the opportunity for stable intense SC generation and its applications in air. | Yaoxiang Liu Fukang Yin Tie-Jun Wang Yuxin Leng Ruxin Li Zhizhan Xu See Leang Chin | 2024 | Light(Science & Applications)2024，13，2： | 0 |
