| 1 | Wafer-scale patterned growth of type-II Dirac semimetal platinum ditelluride for sensitive room-temperature terahertz photodetection显示文摘As the lastly unexplored electromagnetic wave,terahertz(THz)radiation has been exploited in a plenty of contexts such as fundamental research,military and civil fields.Most recently,representative two-dimensional(2D)topological semimetal,platinum ditelluride(PtTe_(2))has attracted considerable research interest in THz detection due to its unique physical properties.However,to achieve practical applications,the low-cost,large-scale,controllable synthesis and efficient patterning of 2D materials are key requirements,which remain a challenge for PtTe_(2)and its photodetectors(PDs).Herein,a facile approach is developed to obtain waferscale(2-inches)patterned PtTe_(2)arrays using one-step tellurium-vapor transformation method and micro-Nano technology.PtTe_(2)PD arrays are fabricated with the as-grown PtTe_(2)arrays evenly distributed on a 2-inch wafer,exhibiting high conductivity(~2.7×105 S m^(-1))and good electrical consistency.Driven by the Dirac fermions,PtTe_(2)PDs achieve a broadband(0.02-0.3 THz)response with a fast response speed(~4.7μs),a high sensitivity(~47 pW Hz^(-1/2))and high-resolution transmission THz-imaging capability,which displays the potential of large-area THz array imaging.These results are one step towards the practical applications of integrated PD arrays based on 2D materials. | Zhuo Dong Wenzhi Yu Libo Zhang Liu Yang Luyi Huang Yan Zhang Zeqian Ren Haoran Mu Cheng Chen Junrong Zhang Jie Li Lin Wang Kai Zhang | 2023 | InfoMat2023，5，5： | 1 |
| 2 | Simulation of incompressible multiphase flows with complex geometry using etching multiblock method显示文摘The incompressible two-phase flows are simulated using combination of an etching multiblock method and a diffuse interface(DI) model, particularly in the complex domain that can be decomposed into multiple rectangular subdomains. The etching multiblock method allows natural communications between the connected subdomains and the efficient parallel computation. The DI model can consider two-phase flows with a large density ratio, and simulate the flows with the moving contact line(MCL) when a geometric formulation of the MCL model is included. Therefore, combination of the etching method and the DI model has potential to deal with a variety of two-phase flows in industrial applications. The performance is examined through a series of numerical experiments. The convergence of the etching method is firstly tested by simulating single-phase flows past a square cylinder, and the method for the multiphase flow simulation is validated by investing drops dripping from a pore. The numerical results are compared with either those from other researchers or experimental data. Good agreement is achieved.The method is also used to investigate the impact of a droplet on a grooved substrate and droplet generation in flow focusing devices. | Haoran LIU Kai MU Hang DING | 2016 | Applied Mathematics and Mechanics(English Edition)2016，37，11： | 1 |
| 3 | Highly stable and repeatable femtosecond soliton pulse generation from saturable absorbers based on twodimensional Cu3-xP nanocrystals显示文摘Heavily doped colloidal plasmonic nanocrystals have attracted great attention because of their lower and adjustable free carrier densities and tunable localized surface plasmonic resonance bands in the spectral range from near-infra to mid-infra wavelengths.With its plasmon-enhanced optical nonlinearity,this new family of plasmonic materials shows a huge potential for nonlinear optical applications,such as ultrafast switching,nonlinear sensing,and pulse laser generation.Cu3-xP nanocrystals were previously shown to have a strong saturable absorption at the plasmonic resonance,which enabled high-energy Q-switched fiber lasers with 6.1μs pulse duration.This work demonstrates that both high-quality mode-locked and Q-switched pulses at 1560 nm can be generated by evanescently incorporating two-dimensional(2D)Cu3-xP nanocrystals onto a D-shaped optical fiber as an effective saturable absorber.The 3 dB bandwidth of the mode-locking optical spectrum is as broad as 7.3 nm,and the corresponding pulse duration can reach 423 fs.The repetition rate of the Q-switching pulses is higher than 80 kHz.Moreover,the largest pulse energy is more than 120μJ.Note that laser characteristics are highly stable and repeatable based on the results of over 20 devices.This work may trigger further investigations on heavily doped plasmonic 2D nanocrystals as a next-generation,inexpensive,and solution-processed element for fascinating photonics and optoelectronics applications. | Haoran MU Zeke LIU Xiaozhi BAO Zhichen WAN Guanyu LIU Xiangping LI Huaiyu SHAO Guichuan XING Babar SHABBIR Lei LI Tian SUN Shaojuan LI Wanli MA Qiaoliang BAO | 2020 | Frontiers of Optoelectronics2020，13，2： | 1 |

| 6 | Probing the dynamic structural changes of DNA using ultrafast laser pulse in graphene-based optofluidic device显示文摘The ultrafast monitoring of deoxyribonucleic acid(DNA)dynamic structural changes is an emerging and rapidly growing research topic in biotechnology.The existing optical spectroscopy used to identify different dynamical DNA structures lacks quick response while requiring large consumption of samples and bulky instrumental facilities.It is highly demanded to develop an ultrafast technique that monitors DNA structural changes with the external stimulus or cancer-related disease scenarios.Here,we demonstrate a novel photonic integrated graphene-optofluidic device to monitor DNA structural changes with the ultrafast response time.Our approach is featured with an effective and straightforward design of decoding the electronic structure change of graphene induced by its interactions with DNAs in different conformations using ultrafast nanosecond pulse laser and achieving refractive index sensitivity of~3×10^(−5) RIU.This innovative technique for the first time allows us to perform ultrafast monitoring of the conformational changes of special DNA molecules structures,including G-quadruplex formation by K+ions and i-motif formation by the low pH stimulus.The graphene-optofluidic device as presented here provides a new class of label-free,ultrafast,ultrasensitive,compact,and cost-effective optical biosensors for medical and healthcare applications. | Bannur NShivananju Lu Zhou Yuefeng Yin Wenzhi Yu Babar Shabbir Haoran Mu Xiaozhi Bao Yiqiu Zhang Sun Tian Qingdong Ou Shaojuan Li Mohammad MHossain Yupeng Zhang Huaiyu Shao Guichuan Xing Nikhil V.Medhekar Chang-Ming Li Jian Liu Qiaoliang Bao | 2021 | InfoMat2021，3，3： | 1 |
| 7 | Interface and surface engineering of black phosphorus: a review for optoelectronic and photonic applications显示文摘Since being rediscovered as an emerging 2D material,black phosphorus(BP),with an extraordinary energy structure and unusually strong interlayer interactions,offers new opportunities for optoelectronics and photonics.However,due to the thin atomic body and the ease of degradation with water and oxides,BP is highly sensitive to the surrounding environment.Therefore,high-quality engineering of interfaces and surfaces plays an essential role in BP-based applications.In this review,begun with a review of properties of BP,different strategies of interface and surfaces engineering for high ON-OFF ratio,enhanced optical absorption,and fast optical response are reviewed and highlighted,and recent state-of-the-art advances on optoelectronic and photonic devices are demonstrated.Finally,the opportunities and challenges for future BP-related research are considered. | Haoran Mu Wenzhi Yu Jian Yuan Shenghuang Lin Guangyu Zhang | 2022 | Materials Futures2022，1，1： | 0 |
| 8 | High tolerance detour-phase graphene-oxide flat lens显示文摘Flat lenses thinner than a wavelength promise to replace conventional refractive lenses in miniaturized optical systems.However,Fresnel zone plate flat lens designs require dense annuli,which significantly challenges nanofabrication resolution.Herein,we propose a new implementation of detour phase graphene flat lens with flexible annular number and width.Several graphene metalenses demonstrated that with a flexible selection of the line density and width,the metalenses can achieve the same focal length without significant distortions.This will significantly weaken the requirement of the nanofabrication system which is important for the development of large-scale flat lenses in industry applications. | SHIBIAO WEI GUIYUAN CAO HAN LIN HAORAN MU WENBO LIU XIAOCONG YUAN MICHAEL SOMEKH BAOHUA JIA | 2021 | Photonics Research2021，9，12： | 0 |

| 10 | Molecular events in the jaw vascular unit:A traditional review of the mechanisms involved in inflammatory jaw bone diseases显示文摘Inflammatory jaw bone diseases are common in stomatology,including periodontitis,peri-implantitis,medication-related osteonecrosis of the jaw,radiation osteomyelitis of the jaw,age-related osteoporosis,and other specific infections.These diseases may lead to tooth loss and maxillofacial deformities,severely affecting patients'quality of life.Over the years,the reconstruction of jaw bone deficiency caused by inflammatory diseases has emerged as a medical and socioeconomic challenge.Therefore,exploring the pathogenesis of inflammatory diseases associated with jaw bones is crucial for improving prognosis and developing new targeted therapies.Accumulating evidence indicates that the integrated bone formation and dysfunction arise from complex interactions among a network of multiple cell types,including osteoblast-associated cells,immune cells,blood vessels,and lymphatic vessels.However,the role of these different cells in the inflammatory process and the'rules'with which they interact are still not fully understood.Although many investigations have focused on specific pathological processes and molecular events in inflammatory jaw diseases,few articles offer a perspective of integration.Here,we review the changes and mechanisms of various cell types in inflammatory jaw diseases,with the hope of providing insights to drive future research in this field. | Ruyu Wang Haoran Wang Junyu Mu Hua Yuan Yongchu Pang Yuli Wang Yifei Du Feng Han | 2023 | The Journal of Biomedical Research2023，37，5： | 0 |
| 11 | Boosting the efficiency of quantum dot–sensitized solar cells over 15%through light-harvesting enhancement显示文摘How to improve the capacity of light-harvesting is still an important point and essential strategy for the assembling of high-efficiency quantum dot–sensitized solar cells(QDSCs).A believable approach is to implant new light absorption materials into QDSCs to stimulate the charge transfer.Herein,the few-layer black phosphorus quantum dots(BPQDs)are synthesized by electrochemical intercalation technology using bulk BP as source.Then the obtained BPQDs are deposited onto the surface of Zn–Cu–In–S–Se(ZCISSe)QD-sensitized TiO2 substrate to serve as another light-harvesting material for the first time.The experimental results have shown that BPQDs can not only increase the absorption intensity by photoanode but also reduce unnecessary charge recombination processes at the interface of photoanode/electrolyte.Through optimizing the size and deposition process of BPQDs,the champion power conversion efficiency of ZCISSe QDSCs is increased to 15.66%(26.88 mA/cm2,Voc=0.816 V,fill factor[FF]=0.714)when compared with the original value of 14.11%(Jsc=25.41 mA/cm^(2),Voc=0.779 V,FF=0.713). | Han Song Haoran Mu Jian Yuan Baiquan Liu Gongxun Bai Shenghuang Lin | 2023 | SusMat2023，3，4： | 0 |
| 12 | Effects of water adsorption on active site-dependent H_(2)activation over MgO nanoflakes显示文摘Understanding the effect of H_(2)O adsorption on reactant activation is of great importance in heterogeneous catalysis,which remains a grand challenge particularly in oxide catalyst systems with structural complexity.Herein,the effect of D_(2)O adsorption on D_(2)activation over MgO nanocatalysts at different temperatures has been investigated by transmission Fourier transform infrared(FT-IR)and temperature-programmed desorption(TPD).Two sets of hydride and hydroxyl species produced from D_(2)dissociation at more active and less active Mg-O pairs can be observed by FT-IR,which all desorb via the product of D_(2)as confirmed by TPD experiments.We find that the physically adsorbed D_(2)O overlayer does not affect the dissociation of D_(2)since D_(2)may pass through the molecular layer and access the surface-active sites.When D_(2)O is partially dissociated on the MgO surface,D_(2)can only dissociate at the remaining active sites until that dissociated-ODw groups from D_(2)O occupy all active sites.These findings provide a fundamental understanding of the effect of water adsorption on D_(2)activation on oxide catalysts. | Aiyi Dong Kun Li Rentao Mu Conghui Liu Rongtan Li Haoran Jia Le Lin Qiang Fu | 2023 | Nano Research2023，16，7： | 0 |
| 13 | Detection and surveillance of circulating tumor cells in osteosarcoma for predicting therapy response and prognosis显示文摘Objective:Osteosarcoma(OS)is an aggressive,highly metastatic,relatively drug-resistant bone tumor with poor long-term survival rates.The presence and persistence of circulating tumor cells(CTCs)in the peripheral blood are believed to be associated with treatment inefficiency and distant metastases.A blood-based CTC test is thus greatly needed for monitoring disease progression and predicting clinical outcomes.However,traditional methods cannot detect CTCs from tumors of mesenchymal origin such as OS,and research on CTC detection in mesenchymal tumors has been hindered for years.Methods:In this study,we developed a CTC test based on hexokinase 2,a metabolic function-associated marker,for the detection and surveillance of OS CTCs,and subsequently explored its clinical value.Twelve patients with OS were enrolled as the training cohort for serial CTC tests.Dynamic CTC counting,in combination with therapy evaluation and post-treatment follow-up,was used to establish a model for predicting post-chemotherapy evaluation and disease-free survival,and the model was further validated with a cohort of 8 patients with OS.Results:Two dynamic CTC number patterns were identified,and the resulting predictive model exhibited 92%consistency with the clinical outcomes.This model suggested that a single CTC test has similar predictive power to serial CTC analysis.In the validation cohort,the single CTC test exhibited 100%and 87.5%consistency with therapy response and disease-free survival,respectively.Conclusions:Our non-invasive test for detection and surveillance of CTCs enables accurate prediction of therapy efficiency and prognosis,and may be clinically valuable for avoiding inefficient therapy and prolonging survival. | Haoran Mu Dongqing Zuo Jie Chen Zhigang Liu Zhuo Wang Liu Yang Qihui Shi Yingqi Hua | 2022 | Cancer Biology & Medicine2022，19，9： | 0 |
