  • Preparation of concealed marks with core-shell luminophores for customs security check system and application thereof
    Patent number: 11232696
    Abstract: Concealed mark preparation with core-shell luminosphores for customs security check system and application thereof, to address that infrared luminescent materials have not been used in senseless customs clearance field, absorption cross sections of infrared luminescent materials currently available are not big enough, and upconversion luminescence intensity thereof is low, consequently, the luminescent marks are not clear enough to recognize marked abnormal luggage, and provide a following solution: step 1: preparing TiQ2; step 2: preparing Ag@TiO2 composite nanoparticles; step 3: preparing Ag@TiQ2@NaYF4:Yb3+, Er3+ luminescent nanoparticles; step 4: making concealed luggage marks.

  • Portable rapid detection device for heavy metal ions and methods of use
    Patent number: 9696278
    Abstract: A portable rapid detection device for heavy metal ions includes a card electrode and a thin-layer flow cell, wherein a three-electrode system of the card electrode is inserted in a micro-channel of the thin-layer flow cell; and heavy metal ions are detected by using an anodic stripping voltammetry (ASV), a solution to be detected flows by the surface of a working electrode in the micro-channel, and heavy metals are enriched and stripped on the surface thereof.
