Among other things, a gas storage system includes a group of capsules and an activation element coupled to the group. The group of capsules are formed within a substrate and contain gas stored at a relatively high pressure compared to atmospheric pressure. The activation element is configured to deliver energy in an amount sufficient to cause at least one of the capsules to release stored gas.

An environmentally responsive Paecilomyces lilacinus microbead and its preparation method and application are provided. The Paecilomyces lilacinus microbead includes a capsule core and a capsule wall; wherein, in the capsule core, Paecilomyces lilacinus spore powder, a vegetable oil, glucose, peptone, a cellulose nanofiber, sodium citrate, and a surfactant are combined to form an emulsifiable capsule core; and in the capsule wall, chitosan, gelatin, polyvinyl alcohol, glycerol, and water are combined to form a water-responsive shell. The environmentally responsive Paecilomyces lilacinus microbeads can stimulate the dissolution of polyvinyl alcohol in the shell according to the moisture content in the soil, so that the water in the soil flows into the microbeads. The cellulose nanofibers in the microbeads absorb water and expand, blocking the holes in the shell, resulting in the inability of spores to flow out.

Various examples of systems and methods for making microspheres, microparticles, and emulsions are provided. In one example, a system and method for forming microspheres comprises: pumping a dispersed phase liquid and a continuous phase liquid into a levitating magnetic impeller pump to subject the dispersed phase liquid and continuous phase liquid to a high shear environment within the impeller pump's pump chamber. In another example, a system and method for forming an emulsion comprises: pumping a dispersed phase liquid and an inner aqueous phase liquid into a levitating magnetic impeller pump to subject the dispersed phase and the inner aqueous phase to a high shear environment within the impeller pump's pump chamber.

A reactor for forming fully coated particles having a solid core, the reactor comprises a reactor vessel which is configured to receive particles, and a gas phase coating mechanism that is configured to selectively introduce pulses of gas phase materials that form a coating on the particles. The reactor also includes a sieve (16) that is located within the reactor vessel, and a forcing means that is configured to force the particles through the sieve (16) in use. The sieve is configured to deagglomerate any particle aggregates formed in the reactor vessel upon forcing of the particles by the forcing means through the sieve.

A preparation method of the microcapsules for low-temperature well cementation to be used to control cement hydration heat includes: (S1) a shell material, and added into deionized water, then the resultant mixture being stirred in a thermostat water bath so as to completely dissolve it into a homogeneous and stable shell material solution; (S2) a core material and an emulsifier being put into a three-necked flask and stirred in a thermostat water bath so as to uniformly emulsify and disperse them, forming a stable oil-in-water core material emulsion, while adjusting the pH value of the emulsion with a pH adjuster; (S3) the three-necked flask containing the core material emulsion being transferred to a water bath, and then the shell material solution being dropwise added into it with stirring, after reacting, a solid-liquid mixture being poured out so as to naturally cool it to room temperature.

There is provided a composition comprising a slurry of capsules, the capsules having shells comprising silica and said shells encapsulating phase change materials (PCM); and a cementitious binder. There is also provided a method for preparing said composition.
