Abstract: Disclosed herein are embodiments of an additively manufactured polysiloxane-based object, as well as composition embodiments for making such object embodiments. Also disclosed are embodiments of a method for making the additively manufactured polysiloxane-based object using the composition embodiments described herein. The disclosed composition embodiments and method embodiments provide objects that are substantially free of contaminants that deleteriously affect structural integrity and that comprise a polymer skeleton consisting of oxygen-silicon bonds wherein the silicon component can further comprise one or more branching groups.

Abstract: A supplemental heating system includes an enclosure that encloses a primary heating device. The enclosure includes an inlet damper, an outlet damper, and an intermediate damper. In an idle state, the inlet damper and outlet damper are open while the intermediate damper is closed. In an active state, the inlet damper and outlet damper are closed while the intermediate damper is open, so that air is circulated within the enclosure.

Abstract: A method of synthesizing multilayer heterostructures including an inorganic oxide layer residing on a solid substrate is described. Exemplary embodiments include producing an inorganic oxide layer on a solid substrate by a liquid coating process under relatively mild conditions. The relatively mild conditions include temperatures below 225° C. and pressures above 9.4 mb. In an exemplary embodiment, a solution of diethyl aluminum ethoxide in anhydrous diglyme is applied to a flexible solid substrate by slot-die coating at ambient atmospheric pressure, and the diglyme removed by evaporation. An AlOx layer is formed by subjecting material remaining on the solid substrate to a relatively mild oven temperature of approximately 150° C. The resulting AlOx layer exhibits relatively high light transmittance and relatively low vapor transmission rates for water. An exemplary embodiment of a flexible solid substrate is polyethylene napthalate (PEN). The PEN is not substantially adversely affected by exposure to 150° C.

Abstract: A method of producing polycrystalline CdTe materials and devices that incorporate the polycrystalline CdTe materials are provided. In particular, a method of producing polycrystalline p-doped CdTe thin films for use in CdTe solar cells in which the CdTe thin films possess enhanced acceptor densities and minority carrier lifetimes, resulting in enhanced efficiency of the solar cells containing the CdTe material are provided.

Abstract: Systems and methods for compensated barrier permeability testing are provided. In one embodiment, a method for testing water vapor penetration through a barrier material comprises: obtaining a first series of resistance measurements from a first moisture sensor located on a substrate surface of a test card, wherein the first moisture sensor is exposed to a testing chamber sealed onto the substrate surface of the test card; obtaining a second series of resistance measurements from a second moisture sensor, wherein the second moisture sensor is isolated from the testing chamber, wherein the testing chamber is defined by a cavity within a spacer element that separates the first moisture sensor from a test barrier; and determining a measurement of water vapor penetration through the test barrier by adjusting the first series of resistance measurement based on the second series of resistance measurement.

Abstract: A test device for measuring permeability of a barrier material. An exemplary device comprises a test card having a thin-film conductor-pattern formed thereon and an edge seal which seals the test card to the barrier material. Another exemplary embodiment is an electrical calcium test device comprising: a test card an impermeable spacer, an edge seal which seals the test card to the spacer and an edge seal which seals the spacer to the barrier material.
