A method of forming a layered structure comprising a domain pattern of a self-assembled material utilizes a negative-tone patterned photoresist layer comprising non-crosslinked developed photoresist. The synthesizer also includes a charge pump that is coupled to the phase detector. One side of the insulating-filler layer comprises a first surface with relatively high pile, including regions of no pile or relatively low pile interspersed among regions of relatively high pile. In one embodiment, the distribution device is a receiver unit and the end user characteristic is viewer location. The methods and systems may include any one or more of an audio event receiving step, a signal discretization step, a masking step, andor a transcription step. The micro-emulsion retains the original active properties of the essential oils in addition to the specific individual properties of the solubilizing agent or the mixture thereof with the lipophilic vegetable materials.
