  • Zwitterionic compounds as gas chromatographic column stationary phases
    Patent number: 11353435
    Abstract: A gas chromatographic (GC) column using a zwitterionic compound and methods of use thereof are disclosed herein. The volatile free acids were observed to strongly retain on these zwitterionic compounds-based columns with excellent peak symmetry. By carefully tuning the structures of these zwitterionic compounds, different selectivity toward volatile free acids was demonstrated. These stationary phases possess a wide working range with thermal stabilities at higher temperatures.

  • SYSTEMS AND METHODS FOR INVERTING THE CHIRP Z-TRANSFORM IN O(n log n) TIME AND O(n) MEMORY
    Publication number: 20210397674
    Abstract: Embodiments of the present disclosure describe an efficient O(n log n) method that implements the Inverse Chirp Z-Transform (ICZT). This transform is the inverse of the well-known forward Chirp Z-Transform (CZT), which generalizes the fast Fourier transform (FFT) by allowing the sampling points to fall on a logarithmic spiral contour instead of the unit circle. Thus, the ICZT can be viewed as a generalization of the inverse fast Fourier transform (IFFT).

  • Microrobotic tentacles with spiral bending capability based on shape-engineered elastomeric microtubes and methods of manufacturing same
    Patent number: 11197726
    Abstract: Elastomer-based soft-robotic micro-tentacles capable of winding around and holding microscale objects and methods of fabricating same are provided. To realize the thin, highly deformable microtubes, a fabrication technique based on in situ thermal solidification of PDMS dip-coated around a cylindrical template and direct peeling of the cured structure is presented. This process is capable to asymmetrize the microtube's cross-sectional shape and enable the microtube to bend up to a single turn. To amplify the bending into a life-like, multi-turn spiraling motion, a semi-analytical model to shape-engineer the microtube and turn it into a micro-tentacle was produced. As a result, a hump is added to the microtube to enable the multi-turn spiraling motion.
