A pour-out member or, for example, a container has a pour-out port 1a through which a viscous fluid is discharged, wherein a hydrophobic layer of fine hydrophobic inorganic particles 20 is selectively formed on an upper end surface of a base member forming the pour-out port 1a. The hydrophobic layer formed on the pour-out port 1a of the pour-out member is not removed or broken through the repetitive use, and stably exhibits a function of preventing the liquid from creeping over extended periods of time.

A stamp for micro-transfer printing includes a body and one or more posts extending from the body. At least one of the posts has a non-planar surface contour on the distal end of the post having a size, shape, or size and shape that accommodates a non-planar contact surface of a micro-transfer printable device.

The disclosure relates to a superhydrophobic surface. Methods of fabrication are disclosed including laminating an optically transparent polymer sheet with hydrophobic nanoparticles such that the nanoparticles are partially embedded and partially exposed. The resulting assembly remains optically transparent. Additional methods include the lamination of nanoparticles to flexible fabrics and the production of molded articles using nanoparticle-treated molds.

An article having a textured surface and a method for manufacturing such an article is provided. The article comprises a polymeric layer coated on at least a portion of the article, a plurality of cavities formed in the polymeric layer, wherein each cavity in the plurality of cavities have a size between about 50 microns to about 2000 microns, and wherein a majority of the plurality of cavities have encircling perimeter ridges, and a plurality of channels formed in the polymeric layer between the encircling perimeter ridges.
