  • Microfluidic chip and a method for the manufacture of a microfluidic chip
    Patent number: 11759782
    Abstract: A novel microfluidic chip is proposed for performing a chemical or biochemical test in a metered reaction volume. The microfluidic chip has a body which defines an inner flow volume. An inlet has been provided to the body for connecting the inner flow volume to the ambient space. A waste channel forms part of the inner flow volume and is in fluid communication with the inlet. A sample channel also forms part of the inner flow volume and is in fluid communication with the inlet. The sample channel includes a first hydrophobic stop and a second hydrophobic stop at a distance from the first hydrophobic stop so as to provide a metered reaction volume there between. An expelling channel is in fluid communication with the metered reaction volume of the sample channel through the first hydrophobic stop. A sample reservoir is in fluid communication with the metered reaction volume of the sample channel through the second hydrophobic stop.

  • Non-combusting smoking article with thermochromatic label
    Patent number: 11197496
    Abstract: A smoking article is disclosed herein. The smoking article includes a shell defining an interior space, a consumable substance within the interior space, a heat source effective to increase the temperature of at least a portion of the shell, and a label attached to at least a portion of the shell. The label includes a base film, a cover film, and a temperature dependent material disposed between the base film and the cover film. The temperature dependent material is configured to transition between a first appearance and a second appearance responsive to the increase of the temperature of at least a portion of the shell.
