  • Publication number: 20200362069
    Abstract: Low molecular weight, highly branched polyolefins are provided. Also provided are catalyst-mediated methods of making the low molecular weight, highly branched polyolefins and a catalyst system for carrying out the methods. The catalyst system is a homogeneous catalytic system that includes a single-site organozirconium complex and hydrocarbon-soluble perfluoroarylborate co-catalyst that is highly active for the oligomerization of olefin monomers in non-polar media.

  • Patent number: 10784848
    Abstract: Van der Waals heterojunctions are extended to semiconducting p-type single-walled carbon nanotube (s-SWCNT) and n-type film that can be solution-processed with high spatial uniformity at the wafer scale. The resulting large-area, low-voltage p-n heterojunctions can exhibit anti-ambipolar transfer characteristics with high on/off ratios. The charge transport can be efficiently utilized in analog circuits such as frequency doublers and keying circuits that are widely used, for example, in telecommunication and wireless data transmission technologies.
