A storage media comprises: a substrate comprising at least one plastic resin portion, wherein the plastic resin portion comprises poly(arylene ether) and a styrene material selected from the group consisting of polystyrene, styrenic copolymer(s), and reaction products and combinations comprising at least one of the foregoing styrene material(s), and at least one data layer on the substrate. The data layer can be at least partly read from, written to, or a combination thereof by at least one energy field. Additionally, when the energy field contacts the storage media, the energy field is incident upon the data layer before it could be incident upon the substrate.

The present invention describes the preparation of maytansinol by methods that minimize processing steps, and reduce solvent volumes, making the process more efficient, and scaleable. This process comprises a step of converting bridged acetals of maytansinol to maytansinol. The simplified processing also aids in lowering the potential for human exposure to chemicals. Also provided is an isolated C3 to C9 bridged acetal of maytansinol.

The result is a thermal spray powder of four distinctly different phases making the powder a four-phase blend.

A ceramic forming batch mixture including inorganic batch materials, such as sources of alumina, titania, and silica, a pore former combination including first and second pore formers with different compositions; an organic binder; and a solvent. Also disclosed is a method for producing a ceramic article involving mixing the inorganic batch materials with the pore former combination having first and second pore formers of different composition, adding an organic binder and a solvent, forming a green body; and firing the green body. A green body having a combination of first and second pore formers with different compositions is disclosed, as are several methods for firing to produce ceramic articles such as aluminum titanate.

A method of co-producing acetic anhydride and an acetate ester includes pyrolizing acetic acid at elevated temperature to produce a first ketene stream, the first ketene stream being a vapor phase stream comprising ketene, acetic acid and water; cooling the first ketene stream to condense acetic acid and water therefrom, thereby generating (i) a weak acid aqueous stream and (ii) a ketene feed stream; feeding the ketene feed stream to an acetic anhydride reactor where the ketene is reacted with acetic acid to produce acetic anhydride; concurrently with step (c), feeding the weak acid aqueous stream to an esterification reactor wherein acetic acid in the weak acid stream is reacted with an organic alcohol to produce an acetate ester. Preferably, the organic alcohol is selected from organic alcohols which (i) form acetate esters which esters and optionally alcohols provide azeotropic mixtures with water and (ii) wherein the azeotropic mixtures have a water content greater than the amount of water generated by reaction of the alcohol with acetic acid to facilitate azeotropically separating the acetate ester from the reaction mixture.

There are disclosed sulfonic acid precursor compositions, as are methods of using these compositions in, for example, photolithography. The compositions are of formula I or formula II:

A process for preparing 3-amino-3-cyclobutylmethyl-2-hydroxypropionamide of the Formula I:or a salt thereof involves providing a compound of the Formula VI described herein in a solution comprising predominately dimethylsulfoxide (DMSO) and converting this compound directly to the compound of the Formula VIII described herein without working up or isolating the intermediate compound of the Formula VII described herein.

A nonaqueous electrolytic solution that can provide a high energy density nonaqueous electrolyte secondary battery having a high capacity, excellent storage characteristics, and excellent cycle characteristics and suppressing the decomposition of an electrolytic solution and the deterioration thereof when used in a high-temperature environment includes an electrolyte, a nonaqueous solvent, and a compound represented by general formula (1):wherein R1, R2, and R3 each independently represent a hydrogen atom, a cyano group, or an optionally halogen atom-substituted hydrocarbon group having 1 to 10 carbon atoms, with the proviso that R1 and R2 do not simultaneously represent hydrogen atoms.
