  • Publication number: 20180356303
    Abstract: Transparent nanocomposites may be used as force sensing materials, either as a transparent piezo-resistive material for resistive force sensing or a transparent dielectric material for capacitive force sensing. The common aspect of these nanocomposites is to engineer the refractive index of the binder to the index of the fillers so that when incorporated into a force sensor the nanocomposite films are optically transparent.

  • Patent number: 10033014
    Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on thews-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

  • Patent number: 9601971
    Abstract: A cooling device for cooling an air-permeable winding braid of an electrical machine is provided. The cooling device includes a baffle and a fan, which is arranged for blowing a stream of cooling air substantially perpendicularly onto a first surface portion of one side of the wind braid, wherein, in the region of a second surface portion of the side of the winding braid, arranged alongside the first surface portion, the baffle is arranged substantially parallel to and that a distance from the surface of the second surface portion such that a partial stream of the stream of cooling air is formed in the channel that is formed by the baffle and the second surface portion, and so, on the side of the winding braid that is opposite from the first-mentioned side, the other partial stream of the stream of cooling air, penetrating the winding braid, flows away from the winding braid without any return flow.

  • Patent number: 9476175
    Abstract: Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.
