Abstract:
Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for monitoring volatile chemicals. A system includes an radio-frequency identification (RFID) tag composed of a patterned metal. The patterned metal is configured to absorb a volatile chemical. The RFID tag includes a non-volatile memory configured to store identification data. The RFID tag also includes a receiver that receives a signal at a frequency in a frequency range. The frequency is based upon an amount of the volatile chemical absorbed in the patterned metal. A transmitter of the RFID tag transmits the identification data in response to receiving the signal. The strength of the transmitted identification data is based upon an amount of the absorbed volatile chemical.

Abstract:
The present technology provides an illustrative method for preparing shaped nanoparticles. The method includes passing a metal vapor to a shaping apparatus and condensing the metal vapor within the shaping apparatus to form selectively-shaped metal nanoparticles. The method may also include forming the metal vapor by heating a bulk metal. In an embodiment, the shaping apparatus comprises a mesh separator that include a plurality of nano-sized, square-shaped pores or a plurality of shaping cups that includes a plurality of recesses.
Abstract:
Polymers, co-polymers, and monomers using CO2 as a reagent and methods of production thereof are described. Polymerization methods include converting CO2 into a polymerizable monomer by exciting the CO2 with a light source. Such polymers and co-polymers can comprise two or more consecutive repeating units of Formula I:
