Polydimethylsiloxane (PDMS) is hailed as one of the foundational materials for microfluidics. Though a silicone‐based elastomer of many desirable properties, the emergence of microfluidic fabrication techniques, especially soft lithography, has elevated its status to an exceptional one. In this mini review, we look at the salient aspects that make PDMS so special in achieving such a coveted status in the microfluidics community. A methodical approach is followed to touch upon the application of PDMS in various aspects of microfluidics with the advantages, limitations, and some future directions. © 2020 Wiley Periodicals, Inc.

“…So far, most of the storage performance of HVMLI cryogenic tanks studies focused on the self-pressurization and thermal stratification in well-insulated conditions [5][6][7][8][9][10][11][12][13][14][15][16]. In a well-insulated HVMLI cryogenic tank, the heat flux leaking into the cryogenic liquid is very low (generally lower than 3.5 W/m 2 ).…”

High-vacuum-multilayer-insulation (HVMLI) cryogenic tank is one kind of dangerous pressure vessels. One of the worst accidents that may occur in a highvacuum-multilayer-insulation (HVMLI) cryogenic tank is a sudden, catastrophic loss of insulating vacuum (SCLIV). The influence of SCLIV on storage performance for a HVMLI cryogenic tank is experimentally studied in this paper. A test rig was built up and experiments were conducted using LN 2 as the test medium. The cryogenic tank was tested in the conditions of various combinations with different initial liquid level and number of insulation layers. Some important conclusions for storage performance with a vacuum-lost HVMLI cryogenic tank have been obtained. The experimental results show that the numbers of insulation layers and the initial liquid level have obvious effect on the storage performance after SCLIV for cryogenic tanks.

Fire exposure of tanks used for the storage and transportation of liquefied gases under pressure may cause complex heat- and mass-transfer phenomena that may contribute to compromise the integrity of the vessels in accident scenarios. Heat transfer through vessel lading results in the heat-up of the internal fluid and the increase of vessel internal pressure. However, local temperature gradients in the liquid phase cause liquid stratification phenomena that result in a more rapid vaporization and pressure build-up in the liquid phase. These fundamental phenomena were analyzed by a computational fluid dynamic model. The model was specifically focused on the early steps of vessel heat-up, when liquid stratification plays a relevant role in determining the vessel internal pressure. A two-dimensional transient simulation was set up using ANSYS FLUENT in order to predict the evolution of the liquid and vapor phases during the tank heat up. The model was validated against large scale experimental data available for liquefied petroleum gas vessels exposed to hydrocarbon fires, and was applied to case studies derived from recent accidental events in order to assess the expected time of pressure build-up in different fire scenarios
