Abstract: A container to hold a quantity of high surface area material. High surface area material has a surface area of greater than about 20 m2/g. The container may be structured in various ways to dispose the high surface area material in the vicinity of a local environment to cause a beneficial effect on that environment. The container may include a moisture permeable wall. The high surface area material may adsorb moisture, and contain and/or emit or off-gas one or more active agent. An exemplary beneficial container may be used for one or more of the following: to control moisture; regulate temperature (e.g., provide either heating or cooling from ambient); promote tissue healing in a human by application of a medicine or treatment agent in vapor phase; destroy microbes and/or bacteria; and destroy or sequester a ripening agent associated with a foodstuff.
