A gas generator comprises a compartment confined by a casing configured to hold an active material generating a target gas in response to thermal activation, and a heater structure configured and arranged to heat the active material for generating the target gas. The heater structure is arranged outside the compartment and heats the active material from at least two sides.

A composition for generating oxygen includes at least one oxygen source selected from chlorates and perchlorates. An oxygen generating device includes such a composition. Oxygen is generated by decomposing such a composition. In the context, phyllosilicate compounds are used as multifunctional components in the oxygen generating compositions.

The present disclosure belongs to the field of single-atom catalytic degradation of refractory organic pollutants, and provides a single-atom catalyst for activation of persulfate to generate pure singlet oxygen (1O2) as well as a preparation method and an application thereof. The single-atom catalyst of the present disclosure includes supports and single iron atoms loaded on the support; the supports are graphitic carbon nitride nanosheets; the single iron atoms are bound to the supports in the form of a Fe—N4 coordination structure. The present disclosure employs graphitic carbon nitride nanosheets as the supports, so that the single iron atoms have a uniform surrounding environment and the persulfate is only converted into 1O2 when being activated; 1O2 has good selectivity and anti-interference ability, so the single-atom catalyst provided in the present disclosure may have excellent selectivity and anti-interference performance in the degradation of organic pollutants.

A cartridge system comprising a container and at least four cartridges for generating oxygen, a compressor for compressing the generated oxygen, at least one storage tank configured to store the compressed oxygen received from the compressor, an oxygen pressure regulator enabling a uniform flow of oxygen at pre-defined oxygen pressure, an oxygen flow control knob regulating flow ratio of the oxygen being supplied to the patient in an instant, a humidifier means imparting humidity to the oxygen being supplied to a patient, and a display unit displaying a set of information associated with the system and communicatively coupled to the portable oxygen generator system 10 via wireless network. The cartridges may be triggered in a plurality of ways to maintain a continuous outflow of generated oxygen for a longer duration. Further, the operation of the system may be monitored or controlled wirelessly from a distant location.

Presented is a portable hand held e-cigarette shaped oxygen generator and air purifier. The device includes a suction body through which atmospheric air is forcibly introduced within a main body of the device during respiration, a solid oxygen filter adapted for holding solid oxygen, and a solid oxygen filter support having a dual cylindrical structure for housing and supporting the solid oxygen filter. The device further includes a solid oxygen filter support lid mountable over the solid oxygen filter support and is adapted for discharging device generated inhalable oxygen from the main body to a micro filter, a casing embodying the micro filter and operationally connected to a mouthpiece having an extension for mounting a straw. The atmospheric air introduced in the device reacts with the solid oxygen to generate inhalable oxygen after passing the atmospheric air through the dual cylindrical structure of the solid oxygen filter support.

Disclosed herein is a method and device for production of a new long-term storage-stable allotropic modification of oxygen, tetraoxygen O.sub.4, using a combination of known chemical reactions into one technological sequence, including chemical interaction of negative and positive oxidation state oxygen compounds.

The method involves production of dioxygen difluoride by oxidation of molecular oxygen with fluorine, followed by the reaction of dioxygen difluoride with alkali metal peroxide, forming tetraoxygen O.sub.4.

Tetraoxygen is stable in its liquid state up to a temperature of +40° C. and can be used for the oxidation of rocket fuel, long-term compact storage of oxygen, and many other purposes.

Disclosed herein is a method for converting light energy into mechanical energy and/or oxygen storage, purification, isolation, concentration, and/or removed. The method may comprise exposing a mixture of a polycyclic aromatic compound and a photosensitizer to oxygen and light to form an endoperoxide, and decomposing the endoperoxide to reform the polycyclic aromatic compound and oxygen. The polycyclic aromatic compound may be a naphthalene compound or anthracene compound and/or may have a formula
