  • Publication number: 20210253950
    Abstract: The invention provides luminescent lanthanide nanoparticles having simultaneously an improved brightness and an increased lifetime of the excited-state. These nanoparticles comprise terbium ions and ions of a second lanthanide, preferentially europium, and are coated with molecules of chromophore ligand bonded to the surface of the nanoparticle. The ligand is an organic molecule comprising at least one chromophore radical of formula (I) or of formula (II): wherein R is selected from H, CN group or COOH group. The phosphorescence excited-state lifetime is improved by energy transfer from surface terbium ions to core ions of the second lanthanide The nanoparticle may further comprise a carrier molecule of analytical interest covalently attached to at least one ligand molecule.

  • Publication number: 20210060509
    Abstract: A reforming reactor and process of using same in which a flow distributor distributes the process gas circumferentially to the reactive zone. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a flow distributor having two horizontal portions connected to opposite ends of a vertical portion.

  • Patent number: 10544613
    Abstract: This invention is about an improved garage door opener system, with design features for preventing garage door break-in from outside of the garage using an object such as a hanger. Typically, a person pulls down a cord connected to a release handle to release emergency release of a garage door opener, allowing the door to be manually open or closed. An unauthorized person may attempt to pull down the cord using a hanger from outside the garage or to pull or push down the release handle, to open the door from outside and gain unauthorized entrance. The improved garage door opener system provides a mechanism to reverse the pulling direction of the cord and also protects release handle from being accessed from outside the garage, for increased security.
