Abstract: The present invention relates to a near-field acoustic platform capable of synthesizing high resolution, arbitrarily shaped energy potential wells. A thin and viscoelastic membrane is utilized to modulate acoustic wavefront on a deep, sub-wavelength scale by suppressing the structural vibration selectively on the platform. This new acoustic wavefront modulation mechanism is powerful for manufacturing complex biologic products.

Abstract: In accordance with a method for performing frequency subchannelization, a digital signal is received at an original sampling rate. A plurality of multirate frequency channels is produced by dividing the digital signal into an integer number of multirate frequency channels such that a sampling rate of each of the multirate frequency channels is proportional to a center frequency of the frequency channel. Signal processing is performed on each of the multirate frequency channels. The original sampling rate is reconstructed using the multirate frequency channels.

Abstract: Disclosed is a sulfide-containing solid electrolyte material with an organic coating, as well as densified pellets containing this solid electrolyte material, a solid electrolyte thereof, and a solid state battery containing the solid electrolyte. According to aspects of the disclosure, the coating comprising a compound of Chemical Formula (1) or Chemical Formula (2) is formed on the surface of a sulfide-containing solid electrolyte material, e.g., the organic coating may comprise a compound having a thiol with a long hydrophobic tail, such as 1-undecanethiol. The coating provides densification of sulfide-containing solid electrolyte materials, and facilitates the ionic and lithium atomic diffusion coefficient at sulfide grain boundaries during pressing, thus achieving the densification of sulfide solid state electrolyte.

Abstract: A method of sensing attributes of an area, a scene or an entity of interest includes receiving at one or more receiving units a signal transmitted from one or more transmitting units, measuring one or more attributes of the received signal; and using, at least in part, wave diffraction principles for sensing. A method, system, and/or device for focusing signal waves, such as for RF field programming, via, at least in part, exploiting principles of diffraction.

Abstract: Phonon engineered, lanthanide doped upconverting nanoparticles with very low phonon energies and tunable methods of synthesis that adjust OA:OM ratio and reaction temperature are provided. Low phonon energy KPb2X5 (X=Cl, Br) upconverting nanoparticles, both doped and undoped, exhibit dramatically suppressed multiphonon relaxation, enhancing upconversion emission from higher lanthanide excited states and enabling room temperature observation of avalanche like upconversion by Nd3+ ions. Intrinsic optical bistability (IOB) of the materials can provide bit level functionality to all optical computing. The IOB of Nd3+ doped nanocrystals, which are either bright or dark at the same excitation power based on power history, illustrate the functionality. High contrast switching and IOB are enabled via the photon avalanche process, which sustains population inversion between the ground and the first excited 4fN states of Nd3+ ions. The IOB of these nanocrystals can be controlled by temporal pump modulation and can store information.

Abstract: Supercooled water or solutions can be destabilized by the nucleation of ice. Constraining water in a constant-volume (isochoric) container minimizes destabilization through thermodynamic, kinetic, and fluid dynamic means, significantly enhancing supercooling stability. Methods and devices are used for stable and transportable supercooling of aqueous solutions or suspensions, and the stable and long-term preservation of biological matter that may be stored therein.
