Nanostructures from laser-ablated nanohole templates

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

Production method of a modeled object

A production method of a modeled object includes a fixing step of fixing a thermally expandable sheet onto a tray by entirely or partially fixing a periphery of the thermally expandable sheet placed on the tray by a fixing member; a thermally expanding step of thermally expanding partially the thermally expandable sheet, which is in a state of being fixed onto the tray by the fixing step, by being heated by irradiating the thermally expandable sheet with light by an irradiation unit, while moving the irradiation unit from a first position toward a second position unit; and cooling the thermally expandable sheet, which has been thermally expanded partially by the thermally expanding step, while maintaining the state in which the thermally expandable sheet is fixed onto the tray, while returning the irradiation unit from the second position to the first position.

Powder Particle Layerwise Three-Dimensional Printing Process
20180236686 · 2018-08-23 · ·

Three-dimensional printing processes are disclosed which utilize printable fluids comprising a carrier fluid, a polymeric binder, and nanoparticles. The three-dimensional printing processes are useful for making articles from a build material powder, e.g., a ceramic, metal, metal alloy, or intermetallic powder. The nanoparticles enable low temperature interparticle bonding of the build material powder particles, e.g., by forming bridging bonds between adjacent powder particles, and/or increasing the interparticle friction between the build material powder particles to enhance the structural strength of the as-built article during a thermal treatment over at least a part of the temperature range which has as its low end the temperature at which the structural strength due to the binder becomes insubstantial and as its high end the temperature at which the structural strength due to interparticle sintering of the build material powder becomes substantial, i.e., the article's debile temperature range. Green density improvements are achievable.

Monofilament-reinforced hollow fiber membrane with scalloped lumen

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilament. When the braid is supported on a plasticized PVA cable having a scalloped periphery, the braid can be infiltrated with membrane polymer which, when coagulated, embeds the braid positioning it around the lumen. The embedded spiral weave, free of any circumferentially constricting monofilament, allows the membrane to be biaxially distensible. The membrane has give not only in the axial or longitudinal direction but also in the radial direction. Give in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.
