摘要:
Described herein are various methods for making textured articles, textured articles that have improved fingerprint resistance, and methods of using the textured articles. The methods generally make use of masks comprising nanostructured metal-containing features to produce textured surfaces that also comprise nanostructured features. These nanostructured features in the textured surfaces can render the surfaces hydrophobic and oleophobic, thereby beneficially providing the articles with improved fingerprint resistance relative to similar or identical articles that lack the texturing.
摘要:
A method of forming an article from a glass sheet (20) having a glass-sheet bonding surface (24) and a glass carrier (10) having a carrier bonding surface (14). At least one of the glass sheet and carrier bonding surfaces is coated with a surface modification layer (30), and then the glass sheet is connected with the carrier via the surface modification layer. From the perimeter of the glass sheet and the carrier while connected, there is removed a portion of the surface modification layer so as to expose a portion (19, 29) of the bonding surface on each of the glass sheet and the carrier. The glass sheet and carrier are then heated at a temperature ≧400° C. so as to bond the perimeter of the glass sheet (26) with the perimeter of the carrier (16).

A method of making an article of a semiconducting material involves selecting a target thickness for the article and then submerging a mold into a molten semiconducting material for a submersion time effective to form a solid layer of semiconducting material over an external surface of the mold where the thickness of the solid layer is substantially equal to the target thickness. The submersion time is selected to be substantially equal to a transition time, which is determined from a plot of solid layer thickness versus submersion time for a mold having particular attributes, including mold composition, mold thickness and initial mold temperature. The transition time, and thus the submersion time, corresponds to a maximum in solid layer thickness in the solid layer thickness versus submersion time curve for the particular mold.

A microfluidic device is described herein which comprises a micron-sized deep flow channel and a sensor. The micron-sized deep flow channel is configured such that a sample solution and a reference solution flow side-by-side to one another in a single sensing region of the sensor. The single sensing region is divided into a detection region and a reference region which are contiguous to one another and which are respectively interfaced with the sample solution and the reference solution that flow side-by-side to one another in a longitudinal direction within the micron-sized deep flow channel.

Superoleophobic substrates and methods of forming same are disclosed. The methods include providing a laser-ablatable substrate comprising glass and directing a laser beam to the substrate surface and laser-ablating at least a portion thereof to form an array of spaced-apart micropillars having sidewalls. The laser beam is provided with sufficient energy to form on the sidewalls an irregular rough surface with re-entrant microscale and nanoscale features that render the substrate surface superoleophobic when coated with a low-surface-energy coating.

Composite carbon electrodes for use in, for example, Capacitive Deionization (CDI) of a fluid stream or, for example, an electric double layer capacitor (EDLC) are described. Methods of making the composite carbon electrodes are also described. The composite carbon electrode comprises an electrically conductive porous matrix comprising carbon; and an electric double layer capacitor, comprising an activated carbonized material, dispersed throughout the pore volume of the electrically conductive porous matrix.

A method of forming a templated casting involves incorporating a liquid feedstock into the channels of a honeycomb substrate to form a feedstock-laden substrate, and directionally solidifying the liquid feedstock within the channels.
摘要:
A glass substrate having an oleophobic surface. The surface is substantially free of features that form a reentrant geometry and includes a plurality of gas-trapping features extending from the surface to a depth below the surface and a coating comprising at least one of a fluoropolymer and a fluorosilane. The gas-trapping features are substantially isolated from each other, and trap gas below droplets to prevent wetting of the surface.
