Non-aqueous solution preparation of doped and undoped lixmnyoz

Boyle, Timothy J; Voigt, James A

Title: Non-aqueous solution preparation of doped and undoped lixmnyoz

Abstract

A method for generation of phase-pure doped and undoped Li.sub.x Mn.sub.y O.sub.z precursors. The method of this invention uses organic solutions instead of aqueous solutions or nonsolution ball milling of dry powders to produce phase-pure precursors. These precursors can be used as cathodes for lithium-polymer electrolyte batteries. Dopants may be homogeneously incorporated to alter the characteristics of the powder.

Preparation of thin ceramic films via an aqueous solution route

Patent Pederson, Larry R [Kennewick, WA]; Chick, Lawrence A [Richland, WA]; Exarhos, Gregory J [Richland, WA]

A new chemical method of forming thin ceramic films has been developed. An aqueous solution of metal nitrates or other soluble metal salts and a low molecular weight amino acid is coated onto a substrate and pyrolyzed. The amino acid serves to prevent precipitation of individual solution components, forming a very viscous, glass-like material as excess water is evaporated. Using metal nitrates and glycine, the method has been demonstrated for zirconia with various levels of yttria stabilization, for lanthanum-strontium chromites, and for yttrium-barium-copper oxide superconductors on various substrates.

Methods and apparatus for preparing aqueous specimens for electron microscopy using volatile surfactants

Patent Glaeser, Robert M.; Han, Bong-Gyoon

This disclosure provides systems, methods, and apparatus related to the preparation of electron microscopy specimens. In one aspect, a method includes providing an electron microscopy grid. An aqueous suspension including an electron microscopy sample is deposited on the electron microscopy grid. A portion of the aqueous suspension is removed from the electron microscopy grid. A volatile surfactant is contacted to the aqueous suspension. A thickness of aqueous suspension is allowed to decrease over a period of time. The aqueous suspension is then frozen.

Process for preparing organoclays for aqueous and polar-organic systems

Patent Chaiko, David J [Naperville, IL]

A process for preparing organoclays as thixotropic agents to control the rheology of water-based paints and other aqueous and polar-organic systems. The process relates to treating low-grade clay ores to achieve highly purified organoclays and/or to incorporate surface modifying agents onto the clay by adsorption and/or to produce highly dispersed organoclays without excessive grinding or high shear dispersion. The process involves the treatment of impure, or run-of-mine, clay using an aqueous biphasic extraction system to produce a highly dispersed clay, free of mineral impurities and with modified surface properties brought about by adsorption of the water-soluble polymers used in generatingmore » « less

Encapsulation of biomaterials in porous glass-like matrices prepared via an aqueous colloidal sol-gel process

Patent Liu, Dean-Mo [Richmond, CA]; Chen, I-Wei [Swarthmore, PA]

The present invention provides a process for the encapsulation of biologically important proteins into transparent, porous silica matrices by an alcohol-free, aqueous, colloidal sol-gel process, and to the biological materials encapsulated thereby. The process is exemplified by studies involving encapsulated cytochrome c, catalase, myoglobin, and hemoglobin, although non-proteinaceous biomaterials, such as active DNA or RNA fragments, cells or even tissues, may also be encapsulated in accordance with the present methods. Conformation, and hence activity of the biomaterial, is successfully retained after encapsulation as demonstrated by optical characterization of the molecules, even after long-term storage. The retained conformation of the biomaterialmore » « less
