The present invention concerns a wall mounted storing construction or system that could hold a number of storing means. A surface of the film is formed with the nanopattern mask, or a nanopattern is machined directly on a surface of the film using E-beam lithograpy such that the biopolymer film exhibits a spectral signature corresponding to the E-beam lithograpy nanopattern. At least one other enclosure encloses electronic components for wirelessly receiving audio and driving at least one driver. A masking layer, the pad layer and the semiconductor substrate are patterned to form a trench therein. A gear reduction unit is also included for establishing high, low and neutral speeds of the first and second output shafts. The amino alcohol A has a structure according to formula where a) R1 and R2, independently of one another, each represent an alkanol group including 3-4 carbon atoms, b) R3 is an organic group including 1-8 carbon atoms, and c) R3 is different from R1 andor R2.
