  • BULK HYDROPHILIC FUNTIONALIZATION OF POLYAMIDE 46
  • 2013
  • Patent (övrigt vetenskapligt/konstnärligt)abstract
    • A modified polymer as result of a bulk functionalization of polyamide 46 (PA 46) is presented, as well as methods for synthesizing the modified polymer. This functionalization of PA 46 is performed to provide a homogenous semi-permeable polyamide 46 capable of different charges and different porosities with particles of nanoscale size in order to replace or improve other polyamide fibers used in the textile industry, filtering processes, selective sorption, controlled release devices, phase transfer catalysts, chromatography media, biocompatible capsules, artificial skins, organs, bone void repair as well as in cell bioreactors and incubators, dental impliments, medical devices, clothing, detectors, perfusion devices, in regenerative medicine, and fuel cells.

  • Waveguide structure
  • 2018
  • Patent (övrigt vetenskapligt/konstnärligt)abstract
    • A waveguide structure for evanescent wave microscopy and/or spectroscopy, comprising an optically transparent core layer, a lower dielectric cladding layer and an upper dielectric cladding layer arranged on opposite sides of the core layer. The core layer has a refractive index higher than the refractive indices of the cladding layers. The upper cladding layer is made of an organic material. A sample well is arranged on an upper surface of the core layer formed by a cavity in the upper cladding layer, the sample well being adapted to contain a sample medium with one or more sample objects. The core layer is made of a first dielectric inorganic material, and the upper cladding layer has a refractive index which closely matches the refractive index of the sample medium. A method for manufacturing such waveguide structure, and a measurement system comprising the waveguide structure are also disclosed.

  • Purification process for trimethylolethane
  • 1996
  • Patent (övrigt vetenskapligt/konstnärligt)abstract
    • A process for combined recovery and purifn. of trimethylolethane from aq. reactions mixts. obtained by reacting formaldehyde with propionic aldehyde in the presence of a metal hydroxide comprises a no. of steps including evapg. the reaction mixt. allowing only trimethylolethane to at least partially crystallize as crude trimethylolethane, evapg. remaining water, heating obtained reaction mixt. and/or obtained crude trimethylolethane, and sublimating trimethylolethane for recovery as purified product
