1高压二氧化碳节流排放堵塞实验显示文摘采用透明玻璃管构造了匹配各种运行情况下安全阀内流道的结构,观测了阀前CO2状态对固体CO2形成和堵塞位置的影响;采用针阀代替安全阀,实验研究了安全阀进口干度、阀开度对安全阀及下游管路中流动堵塞的影响.实验表明:排放蒸气和排放液体同样容易发生堵塞和冻结现象,只是前者在阀内,而后者在阀后管道中;阀开度小时堵塞在阀内,开度大时堵塞在阀后管道中.为了保证安全阀的正常有效运行,建议安全阀出口的管路直径不宜太大,而且应避免向上排放和截面的多次突变.当排放CO2蒸气时应安装消除静电的设施.黄冬平 丁国良 Quack HANS 2006上海交通大学学报2006,40,8:6
2Precision micro-mechanical components in single crystal diamond by deep reactive ion etching显示文摘The outstanding material properties of single crystal diamond have been at the origin of the long-standing interest in its exploitation for engineering of high-performance micro-and nanosystems.In particular,the extreme mechanical hardness,the highest elastic modulus of any bulk material,low density,and the promise for low friction have spurred interest most notably for micro-mechanical and MEMS applications.While reactive ion etching of diamond has been reported previously,precision structuring of freestanding micro-mechanical components in single crystal diamond by deep reactive ion etching has hitherto remained elusive,related to limitations in the etch processes,such as the need of thick hard masks,micromasking effects,and limited etch rates.In this work,we report on an optimized reactive ion etching process of single crystal diamond overcoming several of these shortcomings at the same time,and present a robust and reliable method to produce fully released micro-mechanical components in single crystal diamond.Using an optimized Al/SiO_(2) hard mask and a high-intensity oxygen plasma etch process,we obtain etch rates exceeding 30μm/h and hard mask selectivity better than 1:50.We demonstrate fully freestanding micro-mechanical components for mechanical watches made of pure single crystal diamond.The components with a thickness of 150μm are defined by lithography and deep reactive ion etching,and exhibit sidewall angles of 82°–93°with surface roughness better than 200 nm rms,demonstrating the potential of this powerful technique for precision microstructuring of single crystal diamond.Adrien Toros Marcell Kiss Teodoro Graziosi Hamed Sattari Pascal Gallo Niels Quack 2018Microsystems & Nanoengineering2018,4,1:2

11Integrated silicon ohotonic MEMS显示文摘Silicon photonics has emerged as a mature technology that is expected to play a key role in critical emerging applications,including very high data rate optical communications,distance sensing for autonomous vehicles,photonic-accelerated computing,and quantum information processing.The success of silicon photonics has been enabled by the unique combination of performance,high yield,and high-volume capacity that can only be achieved by standardizing manufacturing technology.Today,standardized silicon photonics technology platforms implemented by foundries provide access to optimized library components,including low-loss optical routing,fast modulation,continuous tuning,high-speed germanium photodiodes,and high-effciency optical and electrical interfaces.However,silicon's relatively weak electro-optic effects result in modulators with a significant footprint and thermo-optic tuning devices that require high power consumption,which are substantial impediments for very large-scale integration in silicon photonics.Microelectromechanical systems(MEMS)technology can enhance silicon photonics with building blocks that are compact,low-loss,broadband,fast and require very low power consumption.Here,we introduce a silicon photonic MEMS platform consisting of high-performance nano-opto-electromechanical devices fully integrated alongside standard silicon photonics foundry components,with wafer-level sealing for long-term reliability,flip-chip bonding to redistribution interposers,and fibre-array attachment for high port count optical and electrical interfacing.Our experimental demonstration of fundamental silicon photonic MEMS circuit elements,including power couplers,phase shifters and wavelength-division multiplexing devices using standardized technology lifts previous impediments to enable scaling to very large photonic integrated circuits for applications in telecommunications,neuromorphic computing,sensing,programmable photonics,and quantum computing.Niels Quack Alain Yuji Takabayashi Hamed Sttari Pieirre Edinger Gaehun Jo Simon JBleker Carlos Errando-Herranz Kristinn BGylfason Frank Niklaus Umar Khan Peter Verheyen Arun Kumar Malik Jun Su Lee Moises Jezzini Padraic Morrissey Cleitus Antony Peter O'Brien Wim Bogaertso 2023Microsystems & Nanoengineering2023,9,2:1
