  • Patent number: 11254156
    Abstract: An approach to printing a nickel precursor ink on a wide range of substrates for electronics and magnetic applications is disclosed. The nickel ink reduces to elemental nickel following heating. The ink was printed using an ultrasonic aerosol printing technique. By sintering the nickel precursor ink in the presence of a homogeneous magnetic field, the reduced nickel complex formed continuously aligned nickel nanofibers axially aligned with the direction of the magnetic field. The fabrication of aligned interlayered nanofiber films provides opportunities to produce structures with enhanced isotropic electrical and magnetic properties. The resistivity of the film was found to be as low as 0.56 m?·cm, and the saturation magnetization was measured to be 30 emu/g, which is comparable to bulk Ni. Magnetic anisotropy was induced with an easy axis along the direction of the applied magnetic field with soft magnetic properties.

  • Publication number: 20210394080
    Abstract: The current disclosure provides a method to improve the performance of evaporators and condensers by maintaining the vapor velocities on the heat exchange surfaces within a desired range. This is accomplished by providing a constant or tapered narrow gap for vapor flow in the heat exchangers. The shear induced by the vapor over the heat exchanger improves the evaporator performance by disturbing the liquid film flowing over the heat transfer surface. In the condenser, the vapor shear helps to remove the condensate in the form of film and droplets, and also removes the non-condensable gases from the heat transfer surfaces as the vapor condenses out and increases the concentration of the non-condensable gases over the heat transfer surfaces. Parameters identified include minimum gap and the taper angle between the cover plate and heat transfer surface.

  • Publication number: 20210219924
    Abstract: An integrated bioinstrumentation system, combining an accurate and robust quasi 1D computational model with experimental peripheral measurements, is designed to extract information on other quantities of interest, for which the direct measurements are not feasible. The system is able to quantify and visualize the distributions of a cardiac output (CO), aortic blood pressure (BP), flow, velocity, and aortic arterial compliance, based on a peripheral analysis of a pulse transit time (PTT) measured at the available peripheral sites. A preliminary calibration stage extracts the arterial properties from simultaneous measurements of a pulse transit time, and an upper arm blood pressure. Obtained transfer functions, linking noninvasive peripheral measurements to the aortic pressure, cardiac output, aortic compliance and others serve to quantify the indicators of cardiac morbidity and mortality.
