Abstract: An optical stack including a periodically varying optical film layer and a grating assembly for reducing moiré is described. The grating assembly includes first and second layers where an interface between the first and second layers define a grating having a peak to valley height and an index contrast. The index contrast multiplied by the peak to valley height may be between 150 nm and 350 nm and the grating has a pitch in the range of 2 micrometers to 50 micrometers. Each of the first and second layers may be viscoelastic or elastomeric adhesive layers, crosslinked resin layers, or soluble resin layers.

Abstract: Optical stacks including a grating structure that generates diffraction in two in-plane dimensions. The optical stacks may include two gratings, which may be one-directional or two-directional, or may include a single two-directional grating. The optical stacks include particles selected to give controlled diffusion of light. The optical stacks are suitable for reducing sparkle in displays.

Abstract: The present disclosure relates to porous electrodes and electrochemical cells and liquid flow batteries produced therefrom. The disclosure further provides methods of making electrodes. The porous electrodes include polymer, e.g. non-electrically conductive polymer particulate fiber, and an electrically conductive carbon particulate. The non-electrically conductive, polymer particulate fibers may be in the form of a first porous substrate, wherein the first porous substrate is at least one of a woven or nonwoven paper, felt, mat and cloth. The porous electrode may have an electrical resistivity of less than about 100000 μOhm·m. The porous electrode may have a thickness from about 10 microns to about 1000 microns. Electrochemical cells and liquid flow batteries may be produced from the porous electrodes of the present disclosure.

Abstract: A sample collection device includes a housing including an exhalation portion and a coupling portion. The coupling portion can be coupled with/to a sample collection tube. An airflow path extends through the housing. The device further includes porous sample collection media partially disposed between within the housing and arranged to occlude the airflow path. The porous sample collection includes nonwoven material and may include polylactic acid, polypropylene, or a combination thereof. The housing can be a single piece, part, or component, or can be multiple pieces, parts, components, or portions. In an embodiment of a two-piece housing, the first part includes an exhalation piece (e.g., a mouthpiece or nosepiece) and the second part includes a coupling end constructed for coupling with a sample collection tube. A method of obtaining a sample using the sample collection device includes breathing into the exhalation piece or portion to collect a sample on the porous sample collection media; coupling the second part or portion with a sample collection tube; and transferring the collected sample on the porous sample collection media into the sample collection tube.

Abstract: A sample collection device including a housing extending from a mouthpiece portion to an air outlet portion. The housing defines an airflow channel from the mouthpiece portion to the air outlet portion. The mouthpiece portion is configured to receive an h exhalation airflow. A porous sample collection media is disposed within the housing and along the airflow channel. A fluid inlet port defines an aperture through the housing and is adjacent to the porous sample collection media. The fluid inlet port is configured to direct id onto the porous sample collection media. A metered fluid dose element is attached to the fluid inlet port. The metered fluid dose element is configured to dispense a metered volume of fluid into the fluid inlet port.
