Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.

A reinforced composite assembly includes a first sheet made of carbon fiber and having a first perimeter, a second sheet made of a non-carbon fiber material and having a second perimeter, wherein the second sheet is disposed atop the first sheet within the first perimeter, and a metallic plate having a third perimeter, wherein the metallic plate is disposed atop the second sheet within the second perimeter. The metallic plate has a plurality of holes formed therein about a perimeter of the metallic plate and defining a plurality of respective bridge portions between each of the holes and an adjacent outer edge of the metallic plate, and/or a plurality of extensions extending outward from a main portion of the metallic plate. A first arrangement of thread stitching secures each of the bridge portions and extensions to the second sheet or to the first and second sheets.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.
