Realization and evaluation of the triple point of sulfur hexafluoride
Metrologia, 2021In this study, we realized the triple point (TP) temperature of sulfur hexafluoride (SF6) at the National Institute of Metrology (NIM), China. To this end, we designed an iso-thermal and immersion type apparatus with an open cell with a height of 18 cm ...

Chemistry - An Asian Journal, 2021
Sulfur hexafluoride (SF6) is considered as a potent greenhouse gas, whose effective degradation is challenging. Here we reported a computational study on the nucleophilic activation of sulfur hexafluoride by N-heterocyclic carbenes and N-heterocyclic ...

Background Perfluorobutane (PFB) and sulfur hexafluoride (SHF) have different physiologic characteristics, but it is unclear whether hepatocellular carcinomas (HCCs) show similar wash-in and washout patterns to both contrast agents at US.

Archives of Otolaryngology - Head and Neck Surgery, 1983
After almost 40 years of experience with antibiotics, treatment of otitis media (which, in the preantibiotic era, was the most common suppurative head and neck infection) still occupies the single largest time effort of the otorhinolaryngologist.1However, the type of fluid and the nature of the complications have changed substantially. Instead of doing

Detecting Decompositions of Sulfur Hexafluoride Using MoS2 Monolayer as Gas Sensor
IEEE Sensors Journal, 2019The adsorption and gas sensing properties of monolayer MoS2 to five kinds of sulfur hexafluoride decompositions (SO2, SOF2, SO2F2, H2S, HF) were explored using the density functional theory combined with the nonequilibrium Green’s function.

IEEE Transactions on Terahertz Science and Technology, 2020
Diffraction of terahertz radiation on ultrasound in liquefied sulfur hexafluoride at room temperature was observed for the first time. The dependences of the diffraction efficiency on the sound frequency, angle of incidence, and amplitude of radio ...
