The present application provides configurations, components, assemblies and methods for sealing cells of sodium-based thermal batteries, such as NaMx cells. In some embodiments the cells may include an integrated bridge member hermetically sealed to an electrically conductive case and a ceramic collar of the cell to hermetically seal an anodic chamber of the cell. In some embodiments the cells may include the ceramic collar hermetically sealed to an electrolyte separator tube of the cell to hermetically seal the anodic chamber of the cell. In some embodiments the anodic chamber may be defined, at least in part, by the case, integrated bridge member, ceramic collar and electrolyte separator tube. In some embodiments the cells may include a current collector hermetically sealed to the ceramic collar, and a cap member hermetically sealed to the current collector tube to hermetically seal a cathodic chamber of the cell.

A nucleic acid-delivery vehicle for delivering nucleic acids to target cells is provided. The nucleic acid-delivery vehicle comprises a plurality of nanoparticles; and a plurality of nucleic acids. The nanoparticles and the nucleic acids are agglomerated to form a nucleic acid-granulation particle having a dimension of at least 5 nm. Methods of making the nucleic acid-delivery vehicle and kits comprising nucleic acid-delivery vehicle are also provided.

Nucleic acid delivery vehicle and uses thereof

Disclosed herein is a system including a motor comprising a rotor, a stator and a sealing assembly having at least one joint and a monolithic ceramic separator. Each joint of the sealing assembly is a chemical bond joint, and the monolithic ceramic separator is disposed in a gap between the rotor and the stator of the motor such that the sealing assembly hermetically isolates the rotor and the stator.

Hermetic sealing assembly and electrical device including the same

Disclosed herein is a spinel article. The article includes a spinel material, wherein the spinel material has a monomodal grain size distribution with average grain sizes of less than or equal to about 15 micrometers, and a biaxial flexural strength of greater than or equal to about 300 megapascals when measured by a ring-on-ring flexural test as per ASTM Standard C1499-08. Disclosed herein too is a method for manufacturing a spinel article, including calcining a spinel powder; milling the powder in a milling medium; granulating the powder; screening the powder to a mesh size of about 40 to about 200 mesh; pressing the powder to form an article; burning out organics from the article; sintering the article; and hot isostatically pressing the article.

Disclosed herein is a spinel article. The article comprises a spinel material, wherein the spinel material has a monomodal grain size distribution with average grain sizes of less than or equal to about 15 micrometers, and a biaxial flexural strength of greater than or equal to about 300 megapascals when measured by a ring-on-ring flexural test as per ASTM Standard C1499-08. Disclosed herein too is a spinel article manufactured by a method comprising calcining a spinel powder; milling the powder in a milling medium; granulating the powder; screening the powder to a mesh size of about 40 to about 200 mesh; pressing the powder to form an article; burning out organics from the article; sintering the article; and hot isostatically pressing the article.

A transparent, nano-composite material and methods for making structures from this material are provided. In one embodiment, the material is made from a polycrystalline matrix containing dispersed particles of a harder material. The particles are less then about 100 nm. In other embodiments, methods for making structures from the material are provided. In one aspect, the methods include blending precursor powders for the matrix and reinforcing phases prior to forming and sintering to make a final structure. In other aspects, a precursor powder for the matrix is pressed into a green shape, which is partially sintered and exposed to a solution containing a precursor for the reinforcing phase, prior to be sintered into the final material. In another aspect, the precursor powder for the matrix is coated with a sol-gel precursor for the reinforcing material, then pressed into a green shape and sintered to form the final structure.

Nano-composite IR window and method for making same

Articles transparent to infrared radiation and resistant to impact and wear are provided. The article comprises a substrate and a composite coating disposed over the substrate and extending from an interface with the substrate to an external surface. The composite coating comprises a first phase and a second phase. The second phase has a higher resistance to erosive wear than the first phase. The coating comprises a compositional gradient proceeding from a first composition at the interface of the coating with the substrate to a second composition at the external surface, the first composition comprising a higher concentration of the first phase than that of the second composition.

Robust window for infrared energy

There is disclosed a pre-sintering process for reducing non-uniformities in the density of a sintered material comprising (a) providing a mixture of (i) a first sinterable material containing a contaminant the presence of which during sintering of the first sinterable material results in a higher vapor pressure than would occur during sintering of pure first sinterable material and (ii) a second material having a higher affinity for the contaminant than does the first sinterable material; and (b) heating the mixture at a temperature and for a time sufficient to allow the second material to at least partly mitigate the propensity of the contaminant to raise the vapor pressure during the sintering of the first sinterable material. Other embodiments are also disclosed.
