摘要:
Ultralyophobe interfaces that are substantially inert to contaminants, thereby resulting in surfaces that are hydrophobic and/or lyophobic. The substrates include a substrate surface and have a bonding layer and a plurality of flexible fibers bound to the bonding layer. The flexible fibers have an elastic modulus and an aspect ratio, wherein as the elastic modulus of the fiber increases, the aspect ratio increases such that the flexible fibers bend upon contact of a liquid surface.

摘要:
A photocatalyst nanocomposite which can be used to destroying biological agents includes a carbon nanotube core, and a photocatalyst coating layer covalently or ionically bound to a surface of the nanotube core. The coating layer has a nanoscale thickness. A method of forming photocatalytic nanocomposites includes the steps of providing a plurality of dispersed carbon nanotubes, chemically oxidizing the nanotubes under conditions to produce surface functionalized nanotubes to provide C and O including groups thereon which form ionic or covalent bonds to metal oxides, and processing a metal oxide photocatalyst sol-gel precursor in the presence of the nanotubes, wherein a nanoscale metal oxide photocatalyst layer becomes covalently or ionically bound to the nanotubes.
摘要:
The invention relates to a method for producing a solid molded article, in particular a ceramic and/or metallic article made of pulverized particles. The invention also relates to stable dispersions of pulverized particles in an aqueous fluid medium, solid molded articles made of pulverized particles, and sintered ceramic and/or metallic molded articles.
摘要:
The invention relates to a casting composition comprising a ceramic powder, an organic solvent, binder, plasticizer and a dispersant, which composition is suitable for producing green ceramic sheets by the tape casting process. The dispersant present in the casting composition of the invention is a polyvinyl alcohol/fatty acid ester having a degree of conversion in the range from 50 to 100%. The invention also relates to the use of such a casting composition for producing ceramic green sheets and a process for producing ceramic substrates using a green sheet thus produced.
摘要:
A method of joining components includes the steps of providing a slurry including a solvent, a ceramic, metal or cermet powder and at least one binder selected from natural monomers or cross linkable polymer compositions. The binder is crosslinked to form a gel. The gel is then placed between the first and at least a second component to be joined. The gel is then sintered to form an article having a gelcast joint binding the first and second components. The resulting joint region will generally have the same strength as the first and second components.
