Abstract: Methods for securely purchasing, sharing and transferring music files using NFC technology. Method of sharing a music playlist using near field communication (NFC), including assigning a playlist Identifier (playlist ID) to a playlist of music files; receiving an NFC Identifier (NFC ID) from an NFC chip using an NFC enabled device; writing the playlist ID to the NFC chip using the NFC enabled device; storing the NFC ID and playlist ID to a server system; receiving the NFC ID and playlist ID from the NFC chip using a subsequent NFC enabled device; authenticating the received NFC ID and playlist ID on the subsequent NFC enabled device with the server system; and if authenticated, streaming the copy of the music files through the subsequent NFC enabled device without downloading the music files into long-term memory.

Abstract: Methods and systems are described for continuously densifying at least one nanofiber sheet using heat and an applied force that can include both compressive and tensile components. Nanofiber sheets densified using these techniques have a more uniform and more highly aligned microstructure than nanofiber sheets densified using a solvent alone. As a result, the nanofiber sheets of the present disclosure have, for example, higher tensile strength and better electrical conductivity than nanofiber sheets densified using other techniques.

Abstract: A nanofiber forest is described that has been processed to increase a number of nanofibers per unit area (referred to as “areal density” or, equivalently, “density”) compared to the nanofiber forest in its as-synthesized state. This increase in areal density is accomplished by physically manipulating a deformable substrate on which the nanofiber forest is disposed. At a high level, this physical manipulation begins by transferring the nanofiber forest from a growth substrate to a deformable substrate. A surface area of the deformable substrate is reduced relative to a surface area of the substrate when the nanofiber forest was attached. This reduction in area causes the nanofibers in the forest to move closer to one another, thus increasing the number of nanofibers per unit area.

Abstract: An article of jewelry comprising a precious or semi-precious gem; a near field communication (NFC) chip; and a bezel, wherein the bezel comprises an electrically conductive material switchable between a closed configuration defined by a continuous electrically conductive loop encircling the NFC chip and an open configuration defined by a gap preventing formation of an electrically conductive loop continuously encircling the NFC chip. Methods of protecting data using the article of jewelry.

Abstract: A nanofiber structure is described that is composed of a substrate and a layer of oriented nanofibers. Nanofibers of the layer can be oriented in a common direction. An angle of the common direction can be selected so that nanofibers of the sheet are oriented at an angle with respect to an underlying substrate even if the underlying substrate is not planar. The angle can be used to adapt the sheets to demands as a thermal interface material.

Abstract: A method of manufacturing an article of jewelry with a druzy or geode effect, the method including: forming an adhesion mixture by mixing metal particles with a silica, shell, and/or clay with polymer, optionally in a liquid to form an adhesion paste; applying the adhesion mixture to an article of jewelry; applying a plurality of gemstones to the applied adhesion mixture to form a gemstone layer; melting the adhesion mixture without significantly melting the article of jewelry; and cooling the adhesion mixture to bond the gemstone layer to the article of jewelry.

Abstract: A nanofiber sheet is described that is composed of a substrate and a layer of oriented nanofibers. Nanofibers of the sheet can be oriented in a common direction. In some orientations, light absorbent sheets can absorb over 99.9%, and in some cases over 99.95%, of the intensity of light incident upon the sheet. Methods for fabricating a light absorbent sheet are also described.
