Abstract: A bipolar membrane composite including a first membrane, a second membrane, an optional additional membrane, a first ion exchange material, a second ion exchange material, and a catalyst. The bipolar membrane composite being configured to create an acidic solution and a basic solution when exposed to a main flow of fluid and an external current supply.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems and methods that include an airflow conditioning device. The airflow conditioning device includes a channels defining airflow pathways through the airflow conditioning device. A heat and moisture exchanger is disposed in the airflow conditioning device with a plurality of air-permeable barriers separating the airflow pathways. The airflow conditioning device includes air-permeable barriers with a layer of a microporous film and a water vapor permeable resin layer adjoined to one or both of the surfaces of the microporous film as either a continuous microporous coating or a discontinuous coating.

Abstract: A textile laminate as described herein comprises a water vapor permeable outward facing protective membrane comprising an inner surface and an outer surface and a textile attached to the inner surface of the membrane, wherein the textile has a surface having a pattern of high regions and low regions. The outer surface of the membrane has a surface topography comprising a pattern of high and low regions that are dimensionally coordinated with a pattern of high and low regions on the surface of the textile.

Abstract: Self-lubricating fastener devices with interlocking rails or interlocking members of a polymer and a slip system additive with a roughening agent and lubricant dispersed throughout the polymer are provided. Methods for production of self-lubricating fastener devices and their use in liquid-resistant or liquid-proof articles are also provided. A particular advantage is the ability of the devices to repeatedly reestablish a self-lubricated surface, even after solvent cleaning.
