Abstract: Disclosed is a composition comprising: (A) at least one fluorine-containing ketone; and (B) an effective amount of stabilizer which is selected from at least one of the group consisting of an epoxy compound, a nitro compound, a hindered phenolic compound, a ?-diketone compound, a phosphite compound, a salicylate compound, a cinnamate compound, a hydroxybenzophenone compound, a hydroxybenzoic acid compound, an alkoxy methane compound, and an organic thio compound. The composition provided by the present invention has stable performance, and can be used as a fire extinguishing agent, a heat transfer medium, etc.

Abstract: Embodiments of systems and methods for medical treatment using a series of pulsed lasers are disclosed. In an example, a system for medical treatment includes a laser source, an optical module, and a controller coupled to the optical module. The laser source is configured to generate a series of pulsed lasers. The optical module is configured to provide a series of focused laser spots on a patient based on the series of pulsed lasers. The controller is configured to control the at least one of the optical module and a stage for holding the patient to move the series of focused laser spots on the patient to form a scan pattern.
