Provided is a three-dimensional object formation powder material used for three-dimensional object formation of forming a three-dimensional object by stacking up a plurality of powder material layers each bound by a resin and having a predetermined shape. The three-dimensional object formation powder material contains particles in which a plurality of cores are fixed by a water-soluble resin.

A porous metallic coating is provided. The coating is characterized by a combination of optimized properties that improve coating performance, as measured by heat transfer efficiency. The porous coating has optimal ranges for properties such as porosity, particle size and thickness, and has particular applicability in boiling heat transfer applications as part of an air separations unit. The porous coatings are derived from slurry-based formulations that include a mixture of metallic particles, a binder and a solvent.

The present invention provides a method for coating seeds with biological materials such as bacteria, fungi (e.g., yeasts and molds), parasites, recombinant vectors, and viruses. The method comprises (a) applying a moistening liquid to seeds to moisten seeds, wherein the moistening liquid comprises a moistening polymer, and (b) coating the moistened seeds with an effective amount of a dry composition, wherein the dry composition comprises biological materials, one or more disaccharides, one or more oligosaccharides, one or more polysaccharides, one or more carboxylic acid salts, and one or more hydrolyzed proteins. The coated seeds may have an initial water activity (Aw) below 0.4, and the microorganisms on the coated seeds have initial viability of at least 5 logs of colony forming units per gram of seeds (CFU/g seed). Also provided are coated seeds.

A three-dimensionally printed article is comprised of a hydroxyethyl methylcellulose (HEMC) having a DS of 1.7 to 2.5 and an MS of at least 0.5, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxyethoxyl groups. The HEMC may advantageously be used as a support material when making a three-dimensionally printed article using a build material such as a different thermoplastic polymer such as a poly(acrylonitrile-butadiene-styrene), polylactic acid, polyethylene and polyprophylene. When the HEMC is a support material it may be easily removed from the build material by contacting the three dimensionally printed article with water, which may be at ambient temperatures and a pH that is neutral or close to neutral.
