  • Publication number: 20190120696
    Abstract: The panoramic-reconstruction temporal imaging (PARTI) system is a single-shot optical waveform measurement apparatus that achieves scalable record length and sub-picosecond resolution simultaneously for ultrafast non-repetitive waveform characterization, in analogy with the wisdom of stitching multiple mosaic images to achieve larger-field-of-view in the spatial domain. It consists of a high-fidelity optical buffer, a low-aberration time magnifier and synchronization-control electronics. For specific measurement circumstances, the PARTI system can also be carried out based on a passive optical buffer, which reduces the system complexity. The PARTI system is configured for real-time single-shot characterization of non-repetitive optical dynamic waveform that evolves over a time scale much larger than that of its ultrafast temporal details, i.e., optical dynamics with large time-bandwidth product.

  • Patent number: 9211506
    Abstract: Disclosed is a membrane surface modification method. The method is applicable to a variety of hydrophobic membranes by doping selected inorganic particles. One act of the method involves the in-situ embedment of the inorganic particles onto the membrane surface by dispersing the particles in a non-solvent bath for polymer precipitation. Further membrane surface modification can be achieved by hydrothermally growing new inorganic phase on the embedded particles. The embedment of particles is for the subsequent phase growth.

  • Publication number: 20150342891
    Abstract: A one-step method for fabricating solidified particles from all-aqueous emulsion droplets involves solidification and drying of the droplets by osmosis. According to this method the fabrication of solidified particles is induced by implementing a high osmotic pressure gradient between the internal phase and external phase of the all-aqueous emulsion. The resultant extraction of water leads to solidification of the emulsion droplets. This approach provides mild conditions for encapsulating bioactive ingredients or other delicate components to conveniently fabricate bio- and cyto-compatible particles because it does not involve the introduction of external energy used in conventional drying. Such conventional external energy inputs are time-consuming, so the method is more efficient.
