Corrosion resistant non-polar polymer coatings and methods for applying the coatings to substrates are described, wherein a source of non-polar polymer powder is deposited as a coating onto the surface of a substrate by high temperature thermal spray. The non-polar character of the powder and any additives thereto is substantially preserved during the high temperature thermal spray process by the use, at one or more locations along the thermal spray route, of at least one non-oxidizing shielding gas, at least one reducing gas, or a combination of the two types of gases to displace or react with ambient oxygen. High velocity impact force (HVIF) spraying techniques are preferred. Similarly processes and materials for low permeability and non-corrosive HVIF coatings for steel fuel tanks are disclosed.

Disclosed is a triple metal line 1T/1C ferroelectric memory device and a method to make the same. A ferroelectric capacitor is connected to the transistor through a buried contact plug. An oxidation barrier layer lies between the contact plug and the lower electrode of the capacitor. A diffusion barrier layer covers the ferroelectric capacitor to prevent diffusion of material into or out of capacitor. As a result of forming the oxidation barrier layer, the contact plug is not exposed to the ambient oxygen atmosphere thereby providing a reliable ohmic contact between the contact plug and the lower electrode. Also, the memory device provides a triple interconnection structure made of metal, which improves device operation characteristics.

A stabilized emulsion is mixed with plasticizable matrix material to produce shelf stable, controlled release, discrete, solid particles or pellets which contain an encapsulated and/or embedded component, such as a readily oxidizable component, such as omega-3 fatty acids. An oil encapsulant component which contains an active, sensitive encapsulant, dissolved and/or dispersed in an oil is admixed with an aqueous component and a film-forming component, such as a protein, to form an emulsion. The emulsion is admixed with a matrix material for obtaining a formable mixture or dough. An acidic antioxidant for prevention of oxidation of the active, sensitive encapsulant, and a plasticizer which solubilizes the acidic antioxidant are included in the matrix material which encapsulates film-coated oil droplets containing the readily oxidizable component. The plasticizer, such as glycerol, provides mobility for the acidic antioxidant within the matrix material of the pellets for reaction with any ambient oxygen and malodorous amines.

Disclosed herein are an apparatus, method and system for storing perishable items that degrade in the presence of oxygen and/or humidity and that are frequently accessed by a consumer. The apparatus comprises an openable vessel, which becomes airtight when closed, and an UV light source and fan within the airtight enclosure, which converts ambient oxygen trapped within the airtight enclosure into ozone by circulating the enclosed volume of air around the UV light source after the vessel is opened and then closed. The apparatus is network connected to allow for remote control and monitoring and sends alerts to web applications or mobile applications when monitored parameters substantially vary from their settings.

A feeder for larval and juvenile fishes is capable of delivering a small (ca. 15 mg) precise dose of microparticulate (ca. 100 μm diameter) feed to selected locations, via pneumatic conveyance and control. A source of low-pressure dry gas is used to blow microparticulate feed through a manifold and into a selected one of a number of tubes. A terminal valve at the end of the tube is selectively activated to send the feed to a selected tank or pond. When not in use, the feeder is sealed, and the feed protected from moisture and ambient oxygen.

A chip scale packaging (CSP) light-emitting device including a light-emitting semiconductor die and a layer-by-layer photoluminescent (PL) structure disposed on the light-emitting semiconductor die is disclosed. The PL structure includes a second PL layer and a first PL layer disposed over the second PL layer, wherein the first PL layer functions as a photoluminescent layer and a barrier layer protecting the second PL from ambient oxygen and moisture. The first PL layer includes a less-moisture-sensitive PL material dispersed within a first polymer matrix material, whereas the second PL layer includes a moisture-sensitive PL material dispersed within a second polymer material. With these arrangements, the outermost first PL layer comprising the less-moisture-sensitive photoluminescent material functions as a wavelength-conversion layer and also serves as a barrier layer protecting the inner second PL layer comprising the moisture-sensitive photoluminescent material from ambient oxygen and moisture. Thus degradation of moisture-sensitive PL material can be reduced.

A stream of sub ambient oxygen from an ion transport membrane is injected into an ambient pressure or super ambient pressure oxygen-consuming process through an annular space in between concentrically disposed inner and outer tubes where a high velocity gas is injected into the process from the inner tube.

Thus, a perovskite dielectric layer can be annealed without the need to provide ultra-high vacuum and/or ultra-high purity ambient environments.
