A porous carbon material suitable for incorporation in smoke filters for cigarettes has a BET surface area of at least 800 m/g and a pore structure that includes mesopores and micropores. The pore volume (as measured by nitrogen adsorption) is at least 0.9 cm/g and from 15 to 65% of the pore volume is in mesopores. The pore structure of the material provides a bulk density generally less than 0.5 g/cc. The material may be produced by carbonizing and activating organic resins and may be in the form of beads for ease of handling.

A system () and method for managing communication session is provided. The system includes a mobile node () that is communicably coupled to a first communication network (). Further, the system includes a first proxy-relay (). The first proxy-relay is communicably coupled to the first communication network and performs one or more functions on behalf of the mobile node. The system also includes a first policy-profile repository () that is communicably coupled to the first communication network. The first policy-profile repository stores a first set of policy-profile definitions describing a first set of services in the first communication network that the mobile node is allowed to access and a first set of rules describing discovery preferences for the mobile mode.

A method of preparing a rod for use in the preparation of a smoking article is described. The rod has a first end and a second end. The rod has located therein a solid support. The solid support extends in a linear fashion from the first end of said rod to the second end of said rod. At least a portion of said solid support is coated and/or impregnated with an additive. The rod is prepared using rod forming means, wherein said rod forming means comprises a channel ending in an open exit, wherein material may pass through at least part of the channel and leave via the open exit in the form of a rod.
