US Classification:

4147521, 41422202, 414217, 414806, 901 40

Abstract:

A method of conveying a glass substrate utilizing an improved non-contact lifting device. The non-contact lifting device employs the Bernoulli effect to create a pressure differential across the glass substrate. The Bernoulli device of the present invention comprises an increased holding or lifting power, and reduces the opportunity for contact between the device and the glass substrate if the device is tilted with respect the plane of the glass substrate surface.

Abstract:

Methods of continuous fabrication of features in flexible substrates are disclosed. In one embodiment, a method of fabricating features in a substrate web includes providing the substrate web arranged in a first spool on a first spool assembly, advancing the substrate web from the first spool and through a laser processing assembly comprising a laser, and creating a plurality of defects within the substrate web using the laser. The method further includes advancing the substrate web through an etching assembly and etching the substrate web at the etching assembly to remove glass material at the plurality of defects, thereby forming a plurality of features in the substrate web. The method further includes rolling the substrate web into a final spool.

International Classification:

C01B 31/12
H01G 11/34

Abstract:

The disclosure relates, in various embodiments, to methods for forming activated carbon comprising (a) providing a feedstock mixture comprising a carbon feedstock, at least one activating agent chosen from alkali metal hydroxides, and at least one additive chosen from fats, oils, fatty acids, fatty acid esters, and polyhydroxylated compounds to form a feedstock mixture; (b) optionally heating the feedstock mixture to a first temperature, and when a step of heating the feedstock mixture to a first temperature is performed, optionally holding the feedstock mixture at the first temperature for a time sufficient to react the at least one activating agent with the at least one additive; (c) optionally milling and/or grinding the feedstock mixture; (d) heating the feedstock mixture to an activation temperature; and (e) holding the feedstock mixture at the activation temperature for a time sufficient to form activated carbon.

International Classification:

C03C 15/00

Abstract:

A method etching a glass material comprises providing an etchant comprising 10-30% HF, 5-15% HNO, and at least 10% HPOby volume constituted such that the ratio HF:HNOby volume is in the range of 1.7:1 to 2.3:1, providing a glass material to be etched, and contacting the glass material with the etchant. The etchant desirably has no other acid components. The method may be performed with the etchant temperature within the range of 20-30 C. The glass material may be an aluminosilicate glass. Ultrasound energy may be applied to the etchant, to the glass material, or both.

International Classification:

C03C 15/00

Abstract:

Methods for forming vias in glass substrates by laser drilling and acid etching are disclosed. In one embodiment, a method forming a via in a glass substrate includes laser drilling the via through at least a portion of a thickness of the glass substrate from an incident surface of the glass substrate. The method further includes etching the glass substrate for an etching duration to increase a diameter of an incident opening of the via and applying ultrasonic energy to the glass substrate during at least a portion of the etching duration. The applied ultrasonic energy has a frequency between 40 kHz and 192 kHz.

International Classification:

C22B 11/02
C22C 5/06

Abstract:

Described herein are methods of making metallic or elemental silver in the solid state. These methods generally include a step of forming an at least substantially solvent-free solid state reaction mixture that includes a silver-containing compound and an organic acid, followed by heating the reaction mixture at a temperature and for a time effective to form metallic silver from a cationic silver species of the silver-containing compound. Also described herein are metallic or elemental silver produced by these methods.
