Abstract:
The present invention relates to a monolithic aerogel comprising organic material and crystalline metal oxide particles, wherein the crystalline metal oxide particles are in a range from 3 to 20 volume percent, based on the total volume of the monolithic aerogel, wherein at least 70 mole percent of the crystalline metal oxide is ZrO2.
Abstract:
A carrier tape includes a longitudinal strip having a plurality of component receiving pockets positioned therein. The pocket depth is greater than a thickness of the longitudinal strip. Adjacent pockets are spaced apart by a distance less than approximately five times the thickness of the longitudinal strip. Sidewalls separating adjacent pockets have a height greater than the pocket depth minus a height of a component which the pockets are configured to receive. The carrier tape is produced by providing a rotatable tool and a nip roll having a conformable outer circumferential surface opposed to the tool. The outer circumferential surface of the tool includes projections for forming the pockets. A polymer web is introduced into a nip between the tool and the nip roll, and embossed with the projections on the circumferential surface of the tool.
Abstract:
The present invention relates to an erosion resistant construction comprising an element of an aircraft comprising an aircraft skin segment having an external surface, and a deicing mechanism associated with said aircraft skin segment capable of heating said external surface to temperatures in excess of 65°C, a tape comprising at least one layer comprising a crosslinked elastomeric polymer, and an adhesive layer, wherein the tape is bonded to the external surface of the aircraft skin segment by the adhesive layer.
Abstract:
Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.
Abstract:
Sample processing devices that include transmissive layers and control layers to reduce or eliminate cross-talk between process chambers in the processing device are disclosed. The transmissive layers may transmit significant portions of signal light and/or interrogation light while the control layers block significant portions of signal light and/or interrogation light. Methods of manufacturing processing devices that include transmissive layers and control layers are also disclosed. The methods may involve continuous forming processes including co-extrusion of materials to form the transmissive layer and control layer in a processing device, followed by formation of the process chambers in the control layer. Alternatively, the methods may involve extrusion of materials for the control layer, followed by formation of process chambers in the control layer.
