| 10 | Design and fabrication of superconducting transition edge sensor bolometers with background limited noise performance显示文摘We successfully designed and fabricated TES bolometers utilizing Al/Ti bilayer TESs as sensitive thermometers.To reduce the intrinsic noise level and tune the saturation power of a bolometer,the TES thermometer is placed on a suspended SiN platform which is thermally coupled to the heat bath by four long SiN beams with different geometries.The measurement results show that the detectors have background limited noise performance,with a low noise equivalent power(NEP)on the order of10-17W/Hz1/2and have a saturation power of several tens pW at a bath temperature of 320 mK.These detectors are suitable for applications in ground-based astrophysics experiments by integrating absorbers for specific wavelengths. | Qingya Zhang Jianshe Liu Wenhui Dong Tianshun Wang Genfang He Tiefu Li Xingxiang Zhou Wei Chen | 2014 | Chinese Science Bulletin2014，59，19： | 1 |

| 12 | 3D Simulation of Battery Fire on a Large Steel Frame Structure due to Depleted Battery Piles显示文摘Lithium ion batteries(LIB)can rupture and result in thermal runaway and battery fires.In the process of transporting lithium ion batteries using trains,the massive collection of batteries can cause train fire and pose significant danger to the public.This is especially critical when the fire occurs amid a heavily populated metropolitan environment.This paper reports the 3D analysis of a warehouse with possible train fire due to LIB rupture and the fire propagation at a rail yard.Six critical fire cases with the battery train in close vicinity to the warehouse were considered.The six fire cases are the worst-case scenarios of a Monte Carlo simulation of different fire cases that may occur to an actual steel storage facility at the Capital Railyard,Raleigh,North Carolina.A 3D finite element(FE)frame model was constructed for the steel warehouse and the most critical fire cases were simulated.The results indicated that several structural components of the warehouse would experience large stresses and deflections during the simulated battery fires and resulting in instability to the structure.Specifically,members of the roof frame represent the most critical elements and that the members can result in large deformations as early as 4 minutes after the fire starts.Furthermore,effective utilization of fire protection can delay somewhat the fire effects and extend time to failure to 45 minutes and in one of the simulated cases,prevent structural instability.Thus,fire from LIB waste transport using train is a very realistic problem due to the thermal runaway,and the analysis performed in current study can be used as a preventive investigation technique for buildings that may be exposed to the train fire risk. | Nicole Braxtan Jorge Nunez Shen-En Chen Tiefu Zhao Lynn Harris Dave Cook | 2022 | Journal of Architectural Environment & Structural Engineering Research2022，5，3： | 0 |
| 13 | Battery Train Fire Risk on a Steel Warehouse Structure显示文摘Lithium ion battery fire hazard has been well-documented in a variety of applications.Recently,battery train technology has been introduced as a clean energy concept for railway.In the case of heavy locomotives such as trains,the massive collection of battery stacks required to meet energy demands may pose a significant hazard.The objective of this paper is to review the risk evaluation processes for train fires and investigate the propagation of lithium ion battery fire to a neighboring steel warehouse structure at a rail repair shop through a case study.The methodology of the analyses conducted include a Monte Carlo-based dynamic modeling of fire propagation potentials,an expert-based fire impact analysis,and a finite element(FE)nonlinear fire analysis on the structural frame.The case study is presented as a demonstration of a holistic fire risk analysis for the lithium ion battery fire and results indicate that significant battery fire mitigations strategies should be considered. | Jasmine Mira Nicole Braxtan Shen-En Chen Tiefu Zhao Lynn Harris Dave Cook | 2021 | Journal of Architectural Environment & Structural Engineering Research2021，4，3： | 0 |

| 15 | Parity-dependent unidirectional and chiral photon transfer in reversed-dissipation cavity optomechanics显示文摘Nonreciprocal elements,such as isolators and circulators,play an important role in classical and quantum information processing.Recently,strong nonreciprocal effects have been experimentally demonstrated in cavity optomechanical systems.In these approaches,the bandwidth of the nonreciprocal photon transmission is limited by the mechanical resonator linewidth,which is arguably much smaller than the linewidths of the cavity modes in most electromechanical or optomechanical devices.In this work,we demonstrate broadband nonreciprocal photon transmission in the reversed-dissipation regime,where the mechanical mode with a large decay rate can be adiabatically eliminated while mediating anti-PT-symmetric dissipative coupling with two kinds of phase factors.Adjusting the relative phases allows the observation of periodic Riemann-sheet structures with distributed exceptional points(Eps).At the Eps,destructive quantum interference breaks both theT-andP-inversion symmetry,resulting in unidirectional and chiral photon transmissions.In the reversed-dissipation regime,the nonreciprocal bandwidth is no longer limited by the mechanical mode linewidth but is improved to the linewidth of the cavity resonance.Furthermore,we find that the direction of the unidirectional and chiral energy transfer could be reversed by changing the parity of the Eps.Extending non-Hermitian couplings to a three-cavity model,the broken anti-PT-symmetry allows us to observe high-order Eps,at which a parity-dependent chiral circulator is demonstrated.The driving-phase controlled periodical Riemann sheets allow observation of the parity-dependent unidirectional and chiral energy transfer and thus provide a useful cell for building up nonreciprocal array and realizing topological,e.g.,isolators,circulators,or amplifiers. | Zhen Chen Qichun Liu Jingwei Zhou Peng Zhao Haifeng Yu Tiefu Li Yulong Liu | 2023 | Fundamental Research2023，3，1： | 0 |
