Collisional Decomposition of Sulfr hexafluoride | NIST

Sep 01, 2000 · Abstract. Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6 is large.Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Sporotrichosis | Fungal Diseases | CDC

SymptomsRisk & PreventionSourcesDiagnosis & TestingTreatmentStatisticsThe symptoms of sporotrichosis depend on where the fungus is growing in the body. Contact your healthcare provider if you have symptoms that you think are related to sporotrichosis. Sporotrichosis usually affects the skin or tissues underneath the skin. The first symptom of cutaneous (skin) sporotrichosisis usually a small, painless bump that can develop any time from 1 to 12 weeks after exposure to the fungus. The bump can be red, pink, or purple, and usually appears on the finger, hand, or arm where the fungus has entered through a break in the skin. The bump will eventually grow larger and may look like an open sore or ulcer that is very slow to heal. Additional bumps or sores may appear later near the original one. Pulmonary (lung) sporotrichosisis rare. Symptoms include cough, shortness of breath, chest pain, and fever. Symptoms of disseminated sporotrichosisdepend on the body part affected. For example, infection of the joints can cause joint pain that may be confused with rhe...Get price
