  • Patent number: 10030338
    Abstract: Embodiments are directed to recycled asphalt shingle pellets having a soft center with a biofuel or bio-oil diluent, and a harder, water-resistant shell coating. It is believed that by using a biofuel, more recycled asphalt shingles material may be used in the formulation of asphalt cement without compromising the performance grade of the asphalt cement.

  • Patent number: 9971136
    Abstract: The invention relates to a method and a system to achieve spatially (e.g. three-dimensionally) confined photomodulation at the focal volume (50) in a ample (55) mounted in a microscope system, comprising two or more laser light sources (41, 42) emitting light (32, 34) of different wavelengths adapted to excite a material in an identical number of independent excitation steps to a higher vibrational state from which the material relaxes, either emitting a conversion light to be detected (“photoexcitation”) or modulating the spectral properties of the material (“photomodulation”).

  • Patent number: 9352055
    Abstract: Functionalized second harmonic nanoprobes for imaging samples and a method of using such probes to monitor the dynamics different processes using a variety of imaging techniques are provided. The functionalized second harmonic generating (SHG) nanoprobes are comprised of various kinds of nanocrystalline materials that do not possess an inversion symmetry and therefore are capable of generating second harmonic signals that can then be detected by conventional two-photon microscopy, and are provided with functional surface modifications that allow for targeted imaging of a variety of biological and non-biological processes and structures such as cell signaling, neuroimaging, protein conformation probing, DNA conformation probing, gene transcription, virus infection and replication in cells, protein dynamics, tumor imaging and cancer therapy evaluation and diagnosis as well as quantification in optical imaging.

  • Publication number: 20150252534
    Abstract: Embodiments of the present disclosure are directed to compositions of and methods for pelletized recycled asphalt shingles used in asphalt pavement. In particular, the recycled asphalt shingle pellets include a soft center with a biofuel or bio-oil diluent, and a harder, water-resistant shell coating. It is believed that by using a biofuel, such as biodiesel, more recycled asphalt shingles material may be used in the formulation of asphalt cement without compromising the performance grade of the asphalt cement.
