Diffusion and infusion resistant implantable devices and methods for reducing pulsatile pressure are provided. The implantable device includes a balloon implantable within a blood vessel of a patient, e.g., the pulmonary artery. The balloon is injected with a fluid mixture comprising a constituent fluid(s) and a diffusion-resistant gas to provide optimal balloon volume and limit fluid diffusion throughout multiple cardiac cycles. The fluid mixture may be pressurized such that the balloon is transitionable between an expanded state and a collapsed state responsive to pressure fluctuations in the blood vessel.

Disclosed is an electrolyte and a secondary battery containing the same. According to the present disclosure, charging efficiency and output may be improved due to low discharge resistance, and gas generation and thickness increase may be suppressed to provide a secondary battery with long-term lifespan and excellent high temperature capacity retention.

Described herein are methods for the bromine-facilitated synthesis of fluoro-sulfur compounds, that include SF.sub.4, SF.sub.5Cl, SF.sub.5Br and SF.sub.6. The methods described herein generally require lower temperature and pressure, produce higher yields, require less time, do not use corrosive or costly reactants and solvents that are commonly used in the synthesis of the fluoro-sulfur compounds, and do not produce deleterious waste products when compared to previously-used methods.

The present application provides a method of preparing sulfuryl fluoride, including the following steps of: S1) reacting sulfur trioxide steam with barium fluoride to acquire a mixed gas of barium sulphate and sulfuryl fluoride; S2) pickling the mixed gas acquired in step S1 with a concentrated sulfuric acid solution with a concentration of 70-98.3 wt. % to acquire a primary purified sulfuryl fluoride gas; S3) passing the primary purified sulfuryl fluoride gas acquired in step S2 through an aqueous solution with a concentration of 2-10 wt. % selected from at least one of the following: sodium sulfite, sodium bisulfite, sodium pyrosulfite, and sodium thiosulfate, to acquire a sulfuryl fluoride gas.

A plant and a related method for the regeneration of fluorinated compounds, particularly sulfur hexafluoride, includes an inlet section designed to receive a gas mixture with the fluorinated compound to be regenerated, an outlet section designed to convey out the regenerated gas, and a fluid dynamic circuit that connects the inlet section to the outlet section and includes filtering elements. The filtering elements have a separation unit where the gas mixture is brought to a temperature and pressure that cause the fluorinated compound to condense while keeping the other components of the mixture in the gaseous state. The condensed fluorinated compound represents the regenerated compound to be conveyed toward the outlet section.
