A flooring arrangement for an aircraft cabin and an aircraft with the flooring arrangement. The flooring arrangement at least one insulating layer for insulating the cabin; a wire mesh disposed above the at least one insulating layer; a carpet layer disposed above the wire mesh, the carpet layer and the wire mesh being in electrically conductive contact; and at least one resistive element connected to the wire mesh, the wire mesh being structured and arranged for being electrically connected to a conductive structure of the aircraft via the at least one resistive element. The resistive element allows transmission, from the wire mesh to the conductive structure, of electrostatic charges developed on the carpet layer, and impedes transmission, from the conductive structure to the wire mesh, of high current events experienced by the aircraft.

Devices and methods related to a chitosan-enhanced melamine sponge are provided. A method comprises grafting chitosan on the melamine sponge matrix via the chemical with two or more carboxyl groups; and crosslinking the chitosan with crosslinker under a heating procedure to make a more robust melamine sponge with a larger surface and smaller pores. The chitosan-enhanced melamine sponge is used to separate chemicals from water as a gravity flow-driven filter, and it can be compressed and backwashed for regeneration.

An environmentally friendly wallpaper with weathering resistance and contaminating resistance includes a substrate layer and a silicone rubber layer composite and connected together. The wallpaper is prepared by a process of calendering and attaching-pressing for patterning-vulcanizating. The process is simple and the production can be constant, resulting in high efficiencies; the entire process is free of harmful substances and polluters. The prepared wallpaper is environmentally friendly and wholesome, and the wallpaper has superior properties such as weathering resistance, contaminating resistance, flame resistance, moisture resistance and mould resistance.
