  • Patent number: 12059703
    Abstract: A method is provided for coating a surface of a material with a film of porous coordination polymer. A first substrate having a first surface to be coated is positioned in a processing chamber such that the first surface is placed in an opposing relationship to a second surface. The second surface may be provided by a wall of the processing chamber, or in some cases the second surface may be provided by a second substrate to be coated. The first substrate is held such that a gap exists between the first and second surfaces, and the gap is filled with at least one reaction mixture comprising reagents sufficient to form the crystalline film on at least the first surface. A thin gap (e.g., less than 2 mm) between the first and second surfaces is effective for producing a high quality film having a thickness less than 100 ?m. Confining the volume of the reaction mixture to a thin layer adjacent the substrate surface significantly reduces problems with sedimentation and concentration control.

  • Publication number: 20240077448
    Abstract: The disclosure provides a gas permeable electrode and method for making the electrode to create diffusion pathways (or pores) in the metal electrode in a manner that is not destructive to delicate or soft sensing material. A first polymer, which is gas-permeable, is applied as a continuous coating over a surface of the sensing material. A second polymer that is immiscible with the first polymer is applied over a surface of the first polymer (e.g., spray-dry deposition of the second polymer) to form a micro-pattern or a polymeric template. The incompatibility/immiscibility between the first polymer and the second polymer leads to segregation of the second polymer into a pattern of discontinuous bumps, dots, islands or blobs on top of the first polymer. The porous electrode comprises at least one layer of an electrically conductive metal that is deposited over the first and second polymers.

  • Publication number: 20200274080
    Abstract: A film, and a light-emitting device (e.g., an OLED) incorporating the film as an emission layer, have luminescent emitters that are maintained in a desired orientation by incorporating them into a crystalline framework material, such as a metal-organic framework (MOF), covalent organic framework (COF), or porous coordination polymer. The crystal structure in the film has at least one crystallographic axis that is aligned substantially parallel to the planar surface of the film and/or the planar surface of a device substrate on which the film is deposited or grown. The luminescent emitters are held and oriented in the unit cells of the crystalline framework material such that their transition dipoles are substantially parallel to the crystallographic axis, which is in turn substantially parallel to the surface of the film or emission layer of the device through which light is emitted, resulting in improved outcoupling of light.

    Abstract: An array of resonant sensors self-corrects measured values for the effects of environmental conditions, such as operating temperature, pressure or humidity. The resonant sensors have varied frequency responses to N environmental parameters and M chemical parameters. Each of the sensors has a different, non-zero frequency response to at least two of the parameters. The device also comprises at least one detector for detecting frequency responses of the resonant sensors. Individual parameter values are determined for each of the N environmental parameters and M chemical parameters according to the detected frequency responses and a system of equations using calibration terms that relate the frequency responses to the individual parameter values.
