  • Patent number: 10734237
    Abstract: Methods and apparatus for subtractively fabricating three-dimensional structures relative to a surface of a substrate and for additively depositing metal and dopant atoms onto the surface and for diffusing them into the bulk. A chemical solution is applied to the surface of the semiconductor substrate, and a spatial pattern of electron-hole pairs is generated by projecting a spatial pattern of illumination characterized by a specified intensity, wavelength and duration at each pixel of a plurality of pixels on the surface. Charge carriers are driven away from the surface of the semiconductor on a timescale short compared to the carrier recombination lifetime. Such methods are applied to creating a spatially varying doping profile in the semiconductor substrate, a photonic integrated circuit and an integrated photonic microfluidic circuit.

  • Patent number: 10727804
    Abstract: An integrated circuit is a layered device, on a semiconductor substrate, which contains metal electrodes that sandwich a piezoelectric layer, followed by a magnetostrictive layer and a metal coil. The metal electrodes define an electrical port across which to receive an alternating current (AC) voltage, which is applied across the piezoelectric layer to cause a time-varying strain in the piezoelectric layer. The magnetostrictive layer is to translate the time-varying strain, received by way of a vibration mode from interaction with the piezoelectric layer, into a time-varying electromagnetic field. The metal coil, disposed on the magnetostrictive layer, includes a magnetic port at which to induce a current based on exposure to the time-varying electromagnetic field generated by the magnetostrictive layer.

  • Publication number: 20200199092
    Abstract: High aldehyde dehydrogenase 1A1 (ALDH1A1) activity has emerged as a reliable marker for the identification of both normal and cancer stem cells. Herein, is presented AlDeSense, a turn-on green fluorescent probe for aldehyde dehydrogenase 1A1 (ALDH1A1) and Ctrl-AlDeSense, a matching non-responsive reagent. AlDeSense exhibits a 20-fold fluorescent enhancement when treated with ALDH1A1. Through the application of surface marker antibody staining, tumorsphere assays, and assessment of tumorigenicity, the disclosed results show that cells exhibiting high AlDeSense signal intensity have properties of cancer stem cells. Herein, is also reported the development of a red congener, red-AlDeSense. Importantly, red-AlDeSense represents one of only a few examples of a turn-on sensor in the red region using the d-PeT quenching mechanism.

    Abstract: A nonreciprocal device includes a waveguide through which waves at a first frequency propagate with a first wavevector and with a second wavevector in a direction opposite to the first wavevector; a frequency-dependent device that operates within a frequency range and modifies the waves through the waveguide in a way that is dependent on the first frequency; and a set of couplers to couple the waveguide and the frequency-dependent device. Coupling rates of the set of couplers are modulated to enable nonreciprocal coupling, with respect to the frequency-dependent device, of the first wavevector compared to the second wavevector.
