Abstract: The present invention relates to a methods and systems for monitoring and/or characterizing multi-component tablets and for monitoring punch and die surfaces and, more particularly, to methods and systems for in-die and out-of-die monitoring and/or characterizing multi-component tablets based on acoustic and vibrational spectroscopy and for detecting and monitoring stiction and tooling material modifications on punch and die surfaces during compaction based on acoustic/ultrasonic waves.

Abstract: A device and system for coupling light into and out of a photonic integrated circuit. The forked grating coupler device applies a forked grating structure to the design of the diffracting lines in an integrated optics grating coupler to make the device compatible with vortex light beams to or from free space, bulk optics, or special optical fiber that can propagate vortex modes. These diffracting lines, which can be grooves, or ridges, or a photonic metamaterial discontinuity arranged in a continuous or intermittent curve, follow the forked diffraction pattern lobes over a two-dimensional surface. The resulting device can therefore absorb or radiate a vortex beam mode at near-normal incidence to a PIC and transform that vortex mode to a transverse electric (TE) or transverse magnetic (TM) waveguide mode traveling along a slab or strip optical waveguide parallel to the surface of the IC.

Abstract: Solid, or highly viscous, organic electrolytes consisting of alkylimidazolium cation with alkyl, PEGylated and fluorinated side chains of different molecular weights were synthesized and characterized (cf. chemical structures in Schemes 1 and 2). The PEGylated/fluorinated imidazolium iodide is a solid organic electrolyte that has a conductivity of about 2×10?5 S/cm at 30° C. The ionic conductivity could be significantly increased (1.11×10?4 S/cm at 30° C. and S/cm at 2.88×10?3 at 90° C.) by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMlml). The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10?4 S/cm to 2×10?4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I?/I3? redox mediators for DSSCs.
