Gas flares configured to mix and burn multiple gasses are disclosed. According to one aspect, a gas flare head includes a first and second conduit one inside the other to form an interior region between the conduits. The interior region between the conduits is partitioned into multiple channels by a dividing structure. Each channel is configured to route a gas from a source to a mixing chamber where the gasses are mixed and burned.

The present invention generally relates to multiple emulsions, and to methods and apparatuses for making multiple emulsions. A multiple emulsion generally describes larger droplets that contain one or more smaller droplets therein. The larger droplets may be suspended in a third fluid in some cases. These can be useful for encapsulating species such as pharmaceutical agents, cells, chemicals, or the like. In some cases, one or more of the droplets can change form, for instance, to become solidified to form a microcapsule, a liposome, a polymerosome, or a colloidosome. Multiple emulsions can be formed in one step in certain embodiments, with generally precise repeatability, and can be tailored to include one, two, three, or more inner droplets within a single outer droplet (which droplets may all be nested in some cases).
