Abstract: A cobalt-containing phosphate material can comprise lithium (Li) (or, alternatively or additionally other alkali metal(s)), cobalt (Co), phosphate (PO4), and at least two additional metals other than Li and Co (e.g., as dopants and/or metal oxides), and can have a molar ratio of Co to a total amount of Co and the additional metals (e.g., as dopants and/or metal oxides) of at least 0.2, at least 0.3, at least 0.5, at least 0.7, or at least about 0.75. The cobalt-containing phosphate material can have a molar ratio of Co to a total amount of Co and the additional metals (e.g., as dopants and/or metal oxides) ranging from 0.2 to 0.98, from 0.3 to 0.98, from 0.3 to 0.94, from 0.5 to 0.98, from 0.5 to 0.94, or alternatively from 0.5 to 0.9, from 0.7 to 0.9, or from 0.75 to 0.85.

Abstract: A method for preparing stable dispersions of high strength polymers where the polymer particles are micron-sized or submicron-sized and dispersions and dry powders prepared from this method. The method includes swelling the high strength polymer particles and mechanically milling them to reduce particle size. Films, coatings, and other useful articles can be prepared from such dispersions and powders.

Abstract: A device for infusing liquid into material samples includes a container assembly configured to contain multiple material samples submerged in liquid. The material samples have pores containing air or gas. A pressure source and a vacuum source are both operatively connectable to the container assembly and alternately communicable with the container assembly to force the liquid to at least substantially fill the pores. The samples are thus ready for further processing, testing or use. A method of filling pores in material samples with liquid includes supporting multiple material samples within liquid in an airtight container assembly. The method further includes alternately applying a vacuum source and a pressure source to the container assembly, thereby replacing air with liquid in the pores of the material samples.
