A delivery apparatus includes a volatile agent source, a controller, and an emanator material. The volatile agent source stores a volume of a volatile agent such as a fragrance. The volatile agent source includes an outlet for delivery of the volatile agent from the volatile agent source. The controller controls a delivery rate of the volatile agent from the volatile agent source. The emanator material is disposed at approximately the outlet of the volatile agent source. The emanator material absorbs at least a portion of the volatile agent and maintains the volatile agent until the volatile agent evaporates into an ambient environment.

A process is provided for synthesizing synthesis gas from carbon dioxide obtained from atmospheric air or other available carbon dioxide source and water using a sodium-conducting electrochemical cell. Synthesis gas is also produced by the coelectrolysis of carbon dioxide and steam in a solid oxide fuel cell or solid oxide electrolytic cell. The synthesis gas produced may then be further processed and eventually converted into a liquid fuel suitable for transportation or other applications.

A method for delivering a beneficial agent is disclosed in one embodiment of the invention as including a water collection chamber. A water-transporting membrane is provided to communicate with the water collection chamber. An extraction chamber receives water through the water-transporting membrane, expanding the extraction chamber. A dispensing chamber, containing a beneficial agent, is configured to contract upon expanding the extraction chamber. This causes the dispensing chamber to expel the beneficial agent through a subterranean delivery channel, such as a rigid hollow spike. In certain embodiments, a rate adjustment mechanism may control the rate that water is received through the water-transporting membrane, thereby controlling the rate the beneficial agent is expelled. The water-transporting membrane has features that repel osmagent from passing through to the water collection chamber. The method features steady rate performance without refreshing the water chamber and low temperature sensitivity.

Alkali metals and sulfur may be recovered from alkali polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte solution includes an alkali polysulfide and a solvent that dissolves elemental sulfur. A catholyte solution includes alkali metal ions and a catholyte solvent. Applying an electric current oxidizes sulfur in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Sulfur is recovered by removing and cooling a portion of the anolyte solution to precipitate solid phase sulfur. Operating the cell at low temperature causes elemental alkali metal to plate onto the cathode. The cathode may be removed to recover the alkali metal in batch mode or configured as a flexible band to continuously loop outside the catholyte compartment to remove the alkali metal.

摘要:
A device and method for atomizing a liquid for delivery to a target zone are presented. The liquid atomization device may include a liquid reservoir to contain a liquid, and a liquid pathway to receive at least a portion of the liquid from the liquid reservoir. The liquid pathway may include one end communicating with the liquid reservoir, and another end communicating with a target zone. Two electrodes may be placed in the liquid pathway to accommodate the liquid therebetween. An AC power source may be connected to each of the electrodes to generate an alternating current through the liquid, thereby atomizing at least a portion of the liquid for delivery to the target zone.
