摘要:
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.

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.

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 treating a sheet of semiconducting material comprises forming a sinterable first layer over each major surface of a sheet of semiconducting material, forming a second layer over each of the first layers to form a particle-coated semiconductor sheet, placing the particle-coated sheet between end members, heating the particle-coated sheet to a temperature effective to at least partially sinter the first layer and at least partially melt the semiconducting material, and cooling the particle-coated sheet to solidify the semiconducting material and form a treated sheet of semiconducting material.
摘要:
A method of making an article of a semiconducting material involves withdrawing from a melt of molten semiconducting material a solid mold having already formed on an external surface of the mold a solid layer of the semiconducting material. During the act of withdrawal, one or more of a temperature, a force, and a relative rate of withdrawal are controlled in order to achieve one or more desired attributes in a solid overlayer of semiconductor material that is formed over the solid layer during the withdrawal.

Described herein are various methods for making textured articles, textured articles that have improved fingerprint resistance, and methods of using the textured articles. The textured articles generally include a substrate and at least two different sets of nanostructured topographical features that are created in or on a surface of the substrate. Each set of nanostructured topographical features will have at least one average dimensional attribute that is different from that of any other set of nanostructured topographical features.
