Publication number: 20160263882Abstract: A system and method for creating three-dimensional nanostructures is disclosed. The system includes a substrate bonded to a carrier using a bonding agent. The bonding agent may be vaporizable or sublimable. The carrier may be a glass or glass-like substance. In some embodiments, the carrier may be permeable having one or a plurality of pores through which the bonding agent may escape when converted to a gaseous state with heat, pressure, light or other methods. A substrate is bonded to the carrier using the bonding agent. The substrate is then processed to form a membrane. This processing may include grinding, polishing, etching, patterning, or other steps. The processed membrane is then aligned and affixed to a receiving substrate, or a previously deposited membrane. Once properly attached, the bonding agent is then heated, depressurized or otherwise caused to sublimate or vaporize, thereby releasing the processed membrane from the carrier.Type: ApplicationFiled: May 23, 2016Publication date: September 15, 2016Inventors: Henry I. Smith, Corey P. Fucetola, Katherine A. Mirica, Jay J. Fucetola, Dakota S. Freeman

Publication number: 20130133419Abstract: A method for determining the density of contact trace objects with magnetic levitation is described. The density of samples of glitter and of gunpowder was determined, and the feasibility of magnetic levitation as a possible means of characterizing forensic-related evidence is discussed. The magnetic levitation device (composed of two permanent magnets with like poles facing) and the method described provides a means of accurately determining the density of trace objects that is inexpensive, rapid, verifiable, provides documentation, is independent of the specific apparatus or analyst, and provides numerical values (rather than a comparison between questioned and known samples) that may be entered into a searchable database.Type: ApplicationFiled: August 24, 2012Publication date: May 30, 2013Inventors: George M.
