Abstract: The present invention provides monomers, analogs, and/or derivatives of bisphenols substituted with one or more fluoromethyl groups. These monomers, analogs, and/or derivatives can be used to form oligomers and/or polymers, which in turn can be used to make compounds with dielectric properties suitable for dielectric materials, including for example, use in energy dense capacitors. In a preferred embodiment, the compounds can comprise a polycarbonate of a homopolymer, copolymer, and/or terpolymer of a bisphenol with one or more fluoromethyl substitution groups. In an aspect of the invention the compounds chosen can be selected based on various desired characteristics, including, for example, their energy density, glass transition temperature, dielectric loss, and/or dipole density.

Abstract: A wave energy converter and method for extracting energy from water waves maximizes the energy extraction per cycle by estimating an excitation force of heave wave motion on the buoy, computing a control force from the estimated excitation force using a dynamic model, and applying the computed control force to the buoy to extract energy from the heave wave motion. Analysis and numerical simulations demonstrate that the optimal control of a heave wave energy converter is, in general, in the form of a bang-singular-bang control; in which the optimal control at a given time can be either in the singular arc mode or in the bang-bang mode. The excitation force and its derivatives at the current time can be obtained through an estimator, for example, using measurements of pressures on the surface of the buoy in addition to measurements of the buoy position. A main advantage of this approximation method is the ease of obtaining accurate measurements for pressure on the buoy surface and for buoy position, compared to wave elevation measurements.

Abstract: In accordance with the present invention, taught is a high purity germanium crystal growth method utilizing a quartz shield inside a steel furnace. The quartz shield is adapted for not only guiding the flow of an inert gas but also preventing the germanium melt from contamination by insulation materials, graphite crucible, induction coil and stainless steel chamber. A load cell provides automatic control of crystal diameter and helps to ensure exhaustion of the germanium melt. The method is both convenient and effective at producing high purity germanium crystals by relatively low skilled operators.

Abstract: Discovering high capacity and high rate cathodic materials is of paramount importance for the further development of electrochemical energy storage devices. Reported herein is a perfluoroalkylated polymer, integrated with an electronically-conductive backbone and an electron transfer catalyst unit that can serve as a new type of cathodic material reaching practical specific capacity of 919 mAh/g at 2.5 C discharging rate and over 700 mAh/g at 16 C discharging rate. A prepolarization treatment of the cathodic materials further increases working voltage to over 2.1 V versus Li/Li+ in classical PC/LiPF6 electrolyte solution giving maximum specific capacity of 1028 mAh/g and specific energy of 2159 mWh/g.

Abstract: An improved system and method for reading an upconversion response from nanoparticle inks is provided. A is adapted to direct a near-infrared excitation wavelength at a readable indicia, resulting in a near-infrared emission wavelength created by the upconverting nanoparticle inks. A short pass filter may filter the near-infrared excitation wavelength. A camera is in operable communication with the short pass filter and receives the near-infrared emission wavelength of the readable indicia. The system may further include an integrated circuit adapted to receive the near-infrared emission wavelength from the camera and generate a corresponding signal. A readable application may be in operable communication with the integrated circuit. The readable application receives the corresponding signal, manipulates the signal, decodes the signal into an output, and displays and/or stores the output.

Abstract: The present invention relates to a one-step process for preparation of “in-situ” or “ex-situ” self-organized and electrically conducting polymer nanocomposites using thermally initiated polymerization of a halogenated 3,4-ethylenedioxythiophene monomer or its derivatives. This approach does not require additional polymerization initiators or catalysts, produce gaseous products that are naturally removed without affecting the polymer matrix, and do not leave by-product contaminants. It is demonstrated that self-polymerization of halogenated 3,4-ethylenedioxythiophene monomer is not affected by the presence of a solid-state phase in the form of nanoparticles and results in formation of 3,4-polyethylenedioxythiophene (PEDOT) nanocomposites.
