    Abstract: A method of encoding information on a material substrate and a device including the modified material substrate are provided. The method includes providing a material substrate having at least one exposed surface or interior (bulk) location with an initial material state, treating the exposed surface or interior location with an energy source, wherein the energy source encodes encryption information on the exposed surface or interior location to provide a modified material substrate having an exposed surface or interior location with an intermediate material state, and then treating the exposed surface or interior location with an intermediate material state with the energy source to encode decipher information on the exposed surface or interior location to provide a remodified material substrate having an exposed surface or interior location with a final material state.

    Abstract: A system for reducing accidents caused by distracted drivers. The system may form an invisible track using material-impregnated grooves and a radar beam, preventing a vehicle from veering away from a road lane. The material-impregnated grooves (MIGs) within one or more road lanes may include scrap metal. The radar beam may be emitted from a transceiver mounted underneath the vehicle such that backscatter from the MIGs is returned to the transceiver.

    Abstract: Under one aspect, a method of processing a material includes heating a region of the material with a first energy source; exciting an acoustic wave in the material; and transmitting the acoustic wave through the heated region, the heated region changing at least one property of the acoustic wave. The method also can include detecting the change in at least one property of the acoustic wave; characterizing a temperature of the material in the heated region based on the detected change in at least one property of the acoustic wave; and comparing the characterized temperature of the material in the heated region to a threshold. The method further can include, based on the characterized temperature of the material in the heated region being less than the threshold or being above the threshold for an insufficient amount of time, modifying a property of the heated region with a second energy source.

    Abstract: Under one aspect of the present invention, a method for enhancing mobility of an atomic or molecular species on a substrate may include exposing a first region of a substrate to an atomic or molecular species that forms a molecular bond with the substrate in the first region; directing a laser pulse to a second region of the substrate so as to generate an acoustic wave in the second region, the acoustic wave having spatial and temporal characteristics selected to alter the molecular bond; and transmitting the acoustic wave from the second region to the first region, the acoustic wave altering the molecular bond between the substrate and the atomic or molecular species to enhance mobility of the atomic or molecular species on the substrate in the first region.
